Sherman Conversion

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

Hi all,
thought I better put myself in the firing line. Im not a master modeller but wanted to try and convert my Mato Sherman into a Regular 75mm Sherman II as used by 4th Armoured Brigade in Normandy. I havn't settled on County of London Yeomanry or 44th RTR yet but theres plenty of time.
So far its a work in progress ! Ive used the Mato Hull, Tamiya Turret and the Base of the Mato 76 turret cut to fit the Tam Turret (quite and easy fix actually) Was Contemplating keeping the cropped 76 Barrel and after endless hours sanding decided its too thick. currently Experimenting with filing down the Airsoft Barrel. Also trying to approximate the 75 mantlet out of the 105 with a lot of card, filing, filling and swearing :crazy:

Now Ive started work on the rest of the turret, with an extra stowage bin of the back, removed the rear fume extractor/ventilation port. Bodged up a loaders hatch and handle.

Might have to settle for a bought Mantlet or even go for the Cam net over the front to hide the knock up job. WIll see how it goes.

Any thoughts or opinions
cheers all
Nick

More work today, Tried shamfering (spelling ??) down an Airsoft barrel by putting it in a drill and using coarse grit paper and a file, sort of worked, but now wish I hadnt got rid of me old Dads lathe :'( .
"Commander" by the way is out of my RC P47 thunderbolt he's been temporarily grounded pending warmer weather :thumbup:

More to do, including,
Take apart suspension (did contemplate the Split spring arm mod thing) Cast a couple of resin wheels for spares. (Might be able to produce a handful of these for interested parties...though I havnt perfected the technique yet.
Work on the Mantlet once the Milliput has completely set and see if a presentable mantlet emerges, Im also trying another method to
produce one, so watch this space for results
Clear out Drivers and Co-drivers compartments, pending a crew. Oh and no doubt loads of other stuff, keep ya posted :D

Trial cast in resin of road wheels. Im doing Bubbajo's suspension conversion too, becoming something of an obsession this conversion.
Tank crew turned up in the post today. They are yanks but may convert to Brits with a lil attention (and some more TIME !)
Photo shows the Original wheels, the silicon rubber moulds and the resin reproductions (with a quick spray of Green) not a bad cast, should be fine for spare wheels as stowage.

More work this evening,
Come to an acceptable conclusion on the mantlet, and the Crew seem really pleased though the skipper is still trying to figure the plans by the looks of things !
DSCF1899a.jpg

Also stripped the suspension right down and sprayed having succesfully completed 1 complete unit split as per Bubbajoes technique ! Boy needs a lot of patience :crazy: I used Humbrols canned spray Light Olive Green, which isnt quite the shade I was after but I think it will weather up well. The finish is really very good out of the can.

Things are progressing. Man If I had any idea how much work in terms of man hours this thing was going to take, Id of stuck with the out of the box look !!! :O
So... oops Tamiya upper hull arrives (well it was cheap as chips and I thought..why not ?) Set to work trying to construct the drivers and co-drivers compartments, after re-angling the Glacis plate from 47 to 56 degrees. Not such a difficult task, as I downloaded a printable protractor and used it as a cutting template.
http://www.ossmann.com/protractor/
Struggled to find a scale plan and looked at thousands of pics for reference...then remembered my 21st 1/18th Sherman was sat there as an ideal model to work from. Sometimes I amaze myself how thick I can be.

Next to the Mato Hull for comparrison, The Tamiya hull is a good fit but you need to shave off about, rough guess 1.5mm off each side of the Mato lower.

With the Turret on for checking fit

Primed to see how rough the sanding had been, and little helpers are keen to get on with the job.

Suspension finished. Ive left the centre suspension units unmodded for now. I figured they would lend a bit of strength to the undercarriage and not detract too much from the effect produced by Bubbajoe's mod.

With reference models, 1/18 to the left and 1/76 matchbox firefly, I built in mm let me see 1979/80ish !!

So now it looks like a sherman again ! sort of. More work to do over the weekend. :D

Nice job on your Sherman. The Mato has lots of room for improvement, but it does provide a good starting point

IF those Shermans start showing up on the island you might want to consider this suspension modification. They are close to being prototypical and you don't cut the traction bars. Tailend Charlie come up with the idea, and I added a few ideas of my own. Seems as some of you guys are still unable to get on to RCU, and since the Firefly is a Brit tank I thought I would share.

I'm on my fourth Sherman.

Thanks YHR, thats remarkable work you've done there, I note that you say the 1/18 wheels are a closer to scale ? They do look better on your Firefly. Think that may be a project too far for me though. Resin wouldnt be up to the job of Road wheels would it ?

As long as you use bearings or at least metal bushings you would probably be OK with Resin
