Hi, this will be a blog about creating a M4A1 based early M50 sherman.

As the base kit I used Eduard's boxing of former Tasca M4A1 sprues, as it is my favourite sherman type and a joy to build. It also helps that this type of intermediate M4A1 was a base for many early M50's.

The M50 specific parts were designed by me, at first as an upgrade for late model M50 from MP models, but then it evolved into an idea to be able to make an M50 with virtually any sherman kit that has 75mm turret. For reference I used drawings and photos from dr. Manasherob's Lioness and Lion of the Line vol.2 book.

Parts were printed via shapeways in their frosted ultra detail resin.

3D M50 conversion includes mantlet, bustle extension, gun travel lock, remanufactured loaders hatch, smoke dischargers as well as empty mounts seen on very early photos of M50s, early infantry telephone box and exhaust deflector. Last part may not be exactly suitable for this type of medium as one of my examples got warped, the other one is ok but it is still on its sprue.

There was also some trial and error around the fillets that meet the original leftover bustle and lower edge of the butle conversion and these details I had to redo with Millput.

Bulk of the sherman is built, now I'm adding small details, welds and so on. To complete the build I will use some pe from old Eduard's PE set for italeri M4A1, commander's all-around vision cupola (preferably bought as a sprue from Asuka) and Bronco's T54E1 tracks.

The resin that the conversion was printed in is semi translucent, so untill I shoot it with primer, it is a little hard to photograph, so bear with me please.

I shaved off al the rivets from the lower hull bottom, but I couldn't be bothered with redoing the reinforcement profiles to the welded style, too much work with visibility on the completed model close to 0.

Glad to see 3D printed parts are getting some love! It looks great so far, can't wait to see how it turns out!

Yes Alan, I think that 3D printig is the future, with the improvement in materials and printers there is a lot to look forward to.

Besides I find 3d modelling less tedious than scratchbuilding, even if in the end it takes more time to complete.

No Timothy, they were not all M4a4 based.
IIRC M4A4 and M4A1 were the earliest, then there where M4 composites, M4 late (large hatch) and even M4A1 Large hatch, basically they used what they could get for the conversions.
All of the above can be seen in photos in Lioness and Lion of the line books.

Cheers,
Greg

Looking good. I think I'll be getting back to my M50's in a month at the earliest. I've got all the parts, only a few other projects are on the table now.

Being able to render your model and be able to see that this component you just added is out of proportion to the rest of the model, then being able to just resize it rather than starting over making a new component can be a timesaver, too.

Got some more work done on my M50!

The turret's almost finished now, just needs welds around mantlet sealing strips and bolts for loaders periscope brush guard. All around vision cupola comes from Tasca sprues purchased separately, these sprues also had the searchlight, FDA steps, rear pintle mount etc. I broke off the 3D printed loaders hatch securing hook, so a replacement was fabricated and placed on a printed base.

IMG_5098 by Grzegorz Ziecina, on Flickr

The hull got a bit more neglected, but I'm catching up on that also. Most work left is located around the engine deck: all the OVM and such. I also have to dress up front hatches and it'll be ready for primer!

Lights and horn brush guards come frome an old Eduard PE set dedicated to Tamiya's M4A3. cover for the horn is thin aluminium foil with four lovely PE bolt heads from old Mig prod. set (without the connectors!). Resin MG barrel is from Eureka XXL.

Rear hull was also detailed: 3D printed infantry phone box, exhaust deflector and gun crutch. Rear stowage tray comes from aforementioned sprue from some late Tasca Sherman, it lacks some details, so these had to be scratchbuilt, together with gun cleaning rods which arangement differs from original as there were 5 segments for French CN 75-50 gun cleaning rod instead of four segments for US 76mm M1A1 gun.

Blanked off cutout in rear upper hull got welds from milliput, though not much of these is visible with remaining details in place.

Spare track brackets again come from Eduard's PE set, track links ale from Bronco workable set I built for this M50.

On the left sponson aft of the turret there is a gun cleaning rod bracket normally mounted on M4 105mm and M4A3 105mm howitzer tanks. I have no Idea why, but most early IDF M4A1 based M50's seem to have this fixture. Also it took me a while to actually find out what it was that I saw in the photos.

Thanks Steven! There are still some interesting details to add to this, which I'll be doing shortly. Here's to hoping it won't be another year before next update

Greg,

Where did that year go? Your tank is looking great, nice job on the added details. I'll save some pictures so I know what to do when I get back to my M50's.

I've been side tracked by earning a living and some Syrian war projects.

Nice work Grzegorz, thats going to look great with some color on! I have not used any 3D printed parts yet, I noticed some faint lines on the parts in your photos, do they disappear under a coat of paint, or do you have to sand them a bit?

Greg,

Should there be welds on the barrel clamp bases? Or were those bolted on?

Thanks Randy, good to hear from you!
In 2 weeks my son will be 1 year old, so I know where my year went

Barrel clamp bases should be welded as far as I know. It's just that I thought I'll get away with leaving the smallest of welds (for example around smoke dischargers brackets)
I guess I'll have to break out the greenstuff and weld it all... I find it difficult to work with such small amounts of milliput, it just doesen't stick.

Thank you John!
Yes, the parts should mostly be sanded a bit, it may depend wether it represents cast part (you'll add texture anyway so why bother?) or rolled plate or sheet metal which should be smoother. I think that with a bit of sanding and mr. surfacer the parinted parts will look good enough.

Thank you for your kind words Gary, Israel and Patrick!

Greg

Greg,

I spend a lot of time with a friends 18 month old, so I know you have your hands full! Elli just got big enough to reach to the near center of my desk so I have to put everything away when she's visiting.

I pay the extra to get the extra fine printing. A little less finishing work.

I bought some of these Shapeways sets in low and high bustle versions and an assorted bunch of Sherman kits with a view to doing some of the early M50 configurations too. I think they look very nice.

Randy, I'll go and try the finer option for printing next time I order!

Thanks Peter, glad you liked the sets!

This time gyus, you didn't have to wait for the update a whole year fortunately!!!

I regard the build finished, added a bunch of welds, minor details and OVM. Might have to add some rolled tarps, a duffel and some backpacks along the road.

I'll sculpt most of it from milliput, but does anyone know if WWII vintage standard US backpack will do on an early IDF sherman?


Added the towing pintle bracket, had to scratchbuild the latchy kind of thingy for it and add welds. Stowage rack got some tidown loops made of stretched sprue.

IMG_5363 by Grzegorz Ziecina, on Flickr

Dressed up the driver's and co-driver's hatches with 0.3 wire and old PE bolt heads grom MIG sets without connectors. Welds were added to sealing strips around the mantlet and smoke dicharger brackets. Also added some rear view mirror hinge parts that are on most of the early IDF M50's. Small, tiny detail barely visible in photos, I'm glad I could identify it at all.

IMG_5356 by Grzegorz Ziecina, on Flickr

IMG_5361 by Grzegorz Ziecina, on Flickr

IMG_5360 by Grzegorz Ziecina, on Flickr

Added all of the OVM, mostly using PE that came with Eduard's Sherman. I also made missing welds on the rear deck and attached towing line, which required the second clamp to be repositioned so the line would not interfere with 105mm cleaning rods rack below it.

IMG_5357 by Grzegorz Ziecina, on Flickr

IMG_5359 by Grzegorz Ziecina, on Flickr

Last but not the least, M50 dressed up in Bronco's tracks general shots. I changed the main gun barrel to a DEF model item , I liked muzzle break's sharpness more than on the Barrel Depot item.

What would cleaning rods for a 105mm be doing on a M50?

Timothy, I haven't got a slightest clue! Maybe they used it for something else? Maybe it was fited by previous owners for another reason?

But they are there in the pictures, always empty though.

How do you make your periscope guards Grzegorz? They all seem so perfect! Do use a jig to bend the shapes, and do you solder them or just glue? Excellent job, bring on the paint!

Thanks John!
Periscope guards are quite easy to make actually! They were glued together with Cyanoacrylate.
Here's how I made them:
First I drilled 4 small holes in the discs that contain the periscope. they mostly have 4 indentations around the periscope, but the ones to make, must be outward of the existing ones. Now would be a good moment to add 4 bolt heads in place of the existing holes (I did that at the end but now it will be easier)
I bend the side elements to fit in the holes (did that by the eye, once I had shape that I liked I bent more parts to match the first one. A jig for this step would be most helpful I think).
Now the sides can be glued in the holes with just a drop of CA. Last thing to do is cut straight sections of wire and attach them between the side trapezoids. (I might have made a mistake here and glued them too far apart, in reality the horizontal bars seem to be closer to eachother. There also might've been more than one design for that part)

Cheers,
Greg
