Hi Guys, I have started on this old partially started M26 hull. I acquired the hull a few years ago in a trade. The Hull was started by another model maker a number of years ago as a custom project, but the project never proceeded beyond the lower hull, and remained in this partially started condition for a number of years.

I have been anticipating this build for some time and I feel that I'm now up for it . For this build I will need to complete the hull, scratch build the turret, and tool up the suspension components, Bow hatches.......ect.

The tank's hull is made out of 1/8th inch thick sheet styrene. Overall the tank appears to have the correct scale, and dimensions. The complex lower hull angles have also been built into this tank.

M26 hull in Raw form.



















The tank's hull was built with an internal wooden frame that acts as support, and anchors several steel angle frames that were to be used as mounting points for the wheel axels. I will be machining my own suspension and torsion bars so the angle frames were not needed and were removed.









When the tank's hull was first built the tank had its fenders built into the structure. These fenders were removed, and sheet metal fenders will be fabricated later. While I was removing the plastic fenders I left 1/4 of an inch of plastic sticking out of the tank's side hull. These strips will be the mounting points for the new fender fasteners.





The tank's rear was built up, and the recess for the final drives have been completed.









The lower portion of the tanks front has also been reworked and is now ready for the next step. In addition to the lower front, the angle frame slots were removed, and two styrene plates were added to the hull sides to create the indent that present on rear portion of the M26 hull. The under hull is now ready for its detailing.









Now that the lower hull is mostly in one piece, the next step is to work on the tank's top hull. More progress to come!

I have made a lot of progress on the tank hull. The tank's upper hull structure has been completed.



The tanks 30.cal , and front air filter blisters have been sculpted onto the tank's front plate.





All of the top hull structure has been sculpted and completed. For the tank's front portion this would include the hatch locations, armored turret ring, top ventilator cover, turret ring blister, and hatch mount extensions. Now that the structure is complete the fine details can be installed.











On the tank's rear portion I have completed the major hull components for the grill work. The grill work themselves will be fabricated after the turret.







To finish up the Lower hull I will now be working on the welds, escape hatches, and access caps. Once these are complete the hull will be ready for the suspension.

To get an idea of what the hull will look like with the turret I placed one of my Sherman Jumbo turrets on the tank's hull.

*Note* This will not be the turret that I will use on the model. Once I have a nice break in the weather I will then be able to fabricate the correct M26 turret.





Another update will follow in the next few days

I completed the tank's lower hull details. These would include the welds, escape hatches, access caps, and drain plugs.









On the M26 the tank's hull was made out of several pieces of both rolled and cast steel. The whole front portion was a single cast assembly that was welded onto the rolled steel plates. The tank's rear portion was comprised of three cast sections that were welded together, and then attached to the tank's hull. To make the cast pieces stand out from the rolled steel panels cast texture was added to the cast sections

















Now that the lower hull mods have been completed, I can now start on fabricating the tank's suspension and running gear.

Thanks, The hull is about, 37 inches long and 15 inches wide (without the fenders).

I have made some progress on the suspension.



I have created and installed the tank's torsion bar swing arm mounts.
Even though there are no M26 kits on the horizon, I will be adding the M26/ M46 suspension to the product line once the suspension is complete. The running gear and suspension will be offered as one complete set, in case there are any other people who are willing to tackle an M26.









The tank's final transmission drives have also been mostly completed and installed. The final drives need a few more smaller details (hull mounting brackets, and oil fillers) to be complete. So here is a sneek peek







In addition to the last of the final drive parts I will now be working on the Bump stops and the return roller mounts. More progress to come!

I have made some more progress on the tank's suspension this week.



I have completed and installed the tank's volute spring bump stops and return roller mounts.







The tank has two types of bump stops. One version is for the swing arms







The other version is for the front Idler wheel swing arms,





I have also added the oil filler caps to the final drives completing the sets. The final drive sets have been added to the product line.

I have made more headway on the suspension.



I have completed the tank's main road wheel swing arms.





The tank's swing arms that connect to the shock absorbers have the shock absorber mounting plate bolted to the rear portion of the swing arms. On the real component all swing arms have a small mounting plate casted into the rear portion of the arm that the shock absorber mount would bolt to. On my resin swing arms I also built in this feature. All of the components also have their grease fittings installed. Once the tank is painted all of these fittings will be painted red.





All of the road wheel swing arms and shock absorbers have been assembled and installed on to the tank.













I will now be focusing on the tank's front road wheel and idler wheel swing arm cluster. Once the cluster is completed I will then be off on the road wheels.

I have completed and installed the final swing arm suspension components.





Before I was able to install any of the cluster components I needed to finish the front swing arm mount. Once complete I was then able to proceed with the installation



The cluster comprises of two swing arms and one shock absorber. The first road wheel and the front idler wheel are both mounted on the large swing arm. The second smaller swing arm connects to the bottom of the large swing arm and it is used for more tension and support for the large idler and road wheel swing arm. For added support the smaller swing arm has a shock absorber mounted to the top of the swing arm.











The front idler wheel connects to the swing arm with a smaller adjustable mount. On the real tank the mount is adjusted with a large hex nut and castle washer positioned on the rear portion of the large swing arm.







With the cluster and the suspension out of the way I have now started on the tank's running gear. I have already completed the tank's small return rollers.



The M26 used the same return rollers found on the M4 Sherman HVSS suspension. The only difference is that the M26 used a different roller hub cap. I already offered the HVSS idler wheels for the Sherman when I was building my T-28 super heavy tank, so I had a good starting point for the new wheels.

My first idler wheels had the M4 HVSS style hub caps molded in. They also were casted flat with no back detailing or structure. While building this model I decided to retool my old idler, with the back structure and detail molded in and with removable hub caps.

I currently have the M26 style hub caps mold created , and I have the M4 style hub caps on the way. Once ready the current M4 rollers will be replaced with the new tooled versions.







The separate hub cap allowed me to mold in a counter sunk divot into the road wheel center. This allows me to install the wheel with a broad head nail. The nail allows the wheel to be mounted securely, yet will allow the wheel to spin freely. The nail head is then concealed with the rein hub cap.









All of the return rollers have been installed and the model is starting to grow outward in it's appearance.











I was also able to add the final smoother cast texture to the front armored plate, more info to follow after the completion of the running gear!



Currently I'm working on the tank's main road wheels. More info to follow!

I have completed and installed the tank's main road wheels. Both the wheels and the return rollers are installed temporarily. They will now be removed so that I can apply the tank's Base coat to the lower hull and the road wheels.







Each road wheel contains two wheels, a center hub, a separate hub cap, and a steel shaft retaining pin. In addition each road wheel is assembled with 10 M3X16 Hex bolts and 10 Nuts.











I designed the hubs with a similar retention system that I used on the return rollers. The hub itself is hollow which contains a space for a steel retention shaft. The shaft secures the wheel to the swing arm, but allows the wheel to spin freely. The resin hub cap then conceals the shaft, and is also in the same position that the real hub cap mounts to the hub. Because of this the seam that is left between the hub and the hub cap is present and is true to the real M26.















Because of the separate hubs the wheels mount to the tank in a very realistic way. It almost makes me want to display the tank with the wheels off!









Due to the design of the wheels they are a lot lighter than the my Late M4 VVSS dish wheels, but take a longer to cast a complete set of 28 wheels compared to 12 for a M4.











Now with the Wheels out of the way the next component that I will be working on now will be the drive sprockets. Once they care complete I then can start producing the masters for the track: Much more to Come!

Thanks for the compliments, They are much appreciated.


I have made some headway with the project







The tank's lower hull and running gear was primed and painted with their base coat



























The All of the Tank's wheels were installed permanently. to their swing arms and idler mounts. The inner rubber tire sections of all the wheels were painted in Black; these sections are difficult to paint once the model is fully detailed and built.



As I mentioned before the wheels are mounted permanently to the tank, but they will be able to spin and roll freely, due to their axle design.











I have just completed The tank's main drive sprockets. Both The drive sprockets and the suspension have been added to the product line.

The Drive sprockets will work for the M26 series, M46, M47 Pattons, and the T30 Heavy / Super heavy tank series.



http://www.eastcoastarmory.com/ustankparts.htm







































The Sprockets are mounted to the tank's final drive mounts with a 1/4 inch steel shaft and spacers. Like the road wheels the sprockets will also spin freely. The large spacer keeps the sprockets in perfect alignment with the road wheels.















With the completion of the sprockets I can now fabricate the Track Masters, which will be molded several times over to produce the necessary links required. I will also now be moving upward to the tank's fenders which will be fabricated out of sheet steel and brass. More info to follow!

It's been a while since I had any progress, but I have been working on the tank's side fenders and fender detail.



Like most late war tanks (comet, Chaffee, JS2) and post WWII tanks (Patton, M60, Centurion, T55) the M26 has a very elaborate and complex fender / storage container design. Because of this the fenders themselves are going to be a very important focal point.

All of the fender components are scratch built and are constructed out of soldered sheet steel and brass. The parts are then mounted to the hull via steel fasteners.

The part of the fenders that was constructed first were the fender support / mount arms. The arms feature the correct "spot weld" seams that are present on the real vehicle. The arms were first attached to the hull with fasteners and glues. Epoxy was then added on top of the fasteners giving the arm more strength, and covering the fasteners with accurate weld seam detail. Small resin hex heads will be added to all of the corner extender points, but this will be after all of the sheet metal fabrication is completed.





















The sheet metal fender panels where then cut, shaped and mounted to the suspending arms. The panels themselves have the side skirt mounting holes drilled into them. The tank's functional storage boxes will be fabricated and soldered directly onto these panels once they are complete.























The next fender parts that need to be created will be the front two fenders and the front and rear mud flaps. Once they are complete it will then be off to the fender storage boxes! More info to come

Thanks Guys, I have made some more progress on the tank's fenders and completed the mud flaps. The tank now has its width complete.





The tank's front fenders were completed first. Unlike the other panels that are simple straight panels of steel the front portions bend inward and overhang the front armored plate. The panel's corners also angle outward from the tank. These panels will also receive 3 stiffener crimps. These crimps will be created out of half round styrene and will be added later.







To mount the tank's front and rear mud flaps to the tank, I had to fabricate the mud flap mounts. The mud flap mounts were installed to the tank with small fasteners and have epoxy weld bead detail added to them





The tank's rear mud flap mount was particularly difficult to fabricate.













Like the rest of the tank's fender components the mud flaps are created out of sheet steel. the mud flaps feature real pressed stiffener crimps. The mud flaps attach to these panels via fasteners.













The tank's rear fenders were very complex to fabricate, I added the distinctive X crimp. The part of the fender that connects to the tank's hull had to be sculpted out of sheet metal. On the later M26A1 and M46, large turn buckles were added to the front and rear portions to the tank's fenders. These were not present on the early production zebra T26.











The tank's storage lockers will be next followed by the tank's turret! More info to come.

Thanks Jesper, This tank without a doubt will have the most elaborate sheet metal work of any of the 1/6th scale tanks that I have built.

As a quick update I have created the sheet metal fender boxes. The fender box interior tool posts have been created and added. The boxes are all sheet metal construction. The tool boxes have a gutter that runs around the edges of the box interior. The gutters are fabricated out of a 1/8th inch brass channel that is soldered into place. I have completed 3 of the gutters, but I ran out of brass stock and have to place the boxes on hold until I can resupply :@.













Once the gutters are complete, the box lids and lid details will be constructed thus finishing off the boxes and fender details.

yeah, sorry about the load times. on other forums the forums divide the thread into pages by the file size of the thread and not the number of posts (like the way Kit Maker Network does it)8-|

I have completed 1/2 of the tank's fenders.



The storage boxes have been completed with the exception of the working latch handles which will be casted in resin shortly. The storage box lids are also all brass / steel construction and all components are soldered together.







The storage container inner lids feature the ridgidity straps and the condensation vent details.











The remaining fender details were added. These would include the rear armored first aid kit container, front fender rigidity crimps, and fender tip hex bolt head details













I will now focus on the fender details on the tank’s other side. Once that is wrapped up I can finally start on the turret

Just a quick update, I completed the tank's right side fenders. With these out of the way





The tank's sheet metal work is now complete. Now that the tin work is completed I can say that this tank has had the most complex and intricate sheet metal work of any of the 1/6th scale tanks that I have built second only to the BRA Jag (which is all sheet metal construction).





The right hand fender boxes were completed and mounted to the fenders. The right hand side boxes and fenders have numerous foot loops soldered to the boxes and to the fenders.













The tank's front horn and brush were also added to the tank. The horn's power cord will be added along with the head lights later.







It is now off to the tank's 90mm turret! More progress to come

I have some progress on the tank's turret.



The tank's turret is fabricated out of a 1/4 inch plywood skeleton. The plywood is then thoroughly coated and soaked with fiberglass resin. The fiberglass resin transforms the wood to plastic.



















The turret's basic body work and shape has been completed. The casted in details for the copula, loaders hatch, and other fittings have been "casted" into the turret's surface.













Currently the turret's surface is far too rough and sanding and filling will be required to finish the turret. The sanding will be the next procedure that I will perform on the model. More info to follow shortly!!

I have finished up the turret body work, and I added cast texture to the surface.







I also built and mounted the armored mantet drum top covering. The mantlet, when installed will then go over this plate. The plate is secured to the tank via slot screws as per the real vehicle.













I'm now fabricating the tank's gun mantlet and gun barrel. more progress to come.

I have made some more progress on the tank's turret.


I have also completed the tank's turret loaders hatch and added it to the product line. The hatch will work for many US tanks of the period including the M4 Sherman, the M4A3E2 Jumbo Sherman, 76mm turreted shamans, and M46 / M47 Pattons.

http://www.eastcoastarmory.com/ustankparts.htm











I have also completed many of the turret details. including the
commanders copula









Retracting 50.cal pintle mount.





Rear turret bustle 50.cal storage racks and pintle.









On the turret's front the gunner's scope, range finder, search light, lift hooks, and loader hatch retaining hatch was added.







The last piece of detail that I added was the foul weather driving hood rack. The rack is all scratch built out of sheet steel and brass.







The Muzzle brake master is completed and is currently in molding. More info to come!

Thanks again guys. I have made some more progress on the tank.







I have added more new parts to the product line. Many of these parts will work on other vehicles besides M26 Pershings.
http://www.eastcoastarmory.com/ustankparts.htm

M3 90mm gun double baffle muzzle brake. This component will work on the M36 and M36B1 Jackson Tank destroyers.







M26 Pershing family Spent shell port hatch kit. This kit will also work on the M46 Patton family.













M26 family T80-E1 Live Track. The track is fully articulated and is very realistically detailed. The track is almost identical to the T80 track that is used on the M4 HVSS suspension. To transform this set for Sherman use I only need to make a different center guide tooth.











The tank's turret detailing is almost complete.



The turret spare track rack was fabricated out of sheet steel. A length of spare track will be mounted once the tank is finished.









The tank's engine removal studs were also added. These studs are only found on early production M26 Pershings.





The remaining turret details have been added. These would include the MP-48 spring antenna base, 50.cal travel lock, and the spent shell port hatch.







The only components that are left on the turret are the track tension jacks. Which will be done very shortly.

Just a quick update I have completed the tank's turret detailing.



I added a second MP-48 spring antenna base, and the tank's track connector ratchet jacks.









I have also added the jacks the product line. These jacks are used to tighten up the space between the two tracks when they are being re connected to insert the last connector block. These jacks are used on all US fully tracked AFV from the 40's to today. These make a great diorama accessory for your tankers.









Now that the turret detailing is mostly complete I will now start on the tank's rear wall detailing. This would include the exhaust manifold, tail lights, how hitch....ect. More info to come!!
