The use of MDF was only to get the size of what I will/would like to sand cast in aluminium, it was cheap and easy to work with. The drive sprocket I did up in CAD then printed it out, my dad was visiting and had his scroll saw so we had a play with it, they turned out very good, but again will try to cast it all somehow.
The wood working if you mean the wooden lower hull, was to mainly to see if I could do it. But as you can see as part of the build the hull is 3mm aluminium plate (was freeby) The S-tank hull has been scraped for now but will plan on starting it again after the Sherman is finished.

I can see however that your material choice is lowering in quality as the build progresses, For your suspension bogies I would have used metal for the arms rather than plywood ,( and I avoid MDF altogether in tank building ). I can see how money (or lack of) will be a big factor in material choice, its the same for me. have a look at the tracks on T068, they can be built to any width to accommodate any wheel, if you can find treadmill, hardwood and 4mm bolts then you can make a very strong durable track. you could design a track that would mesh with your first sprocket, that would be authentic and workable. keep up the very good work Neil R On Mar 11, 2:36 am, Pete <[email protected]> wrote: > Neil, > Try this link for my tank site (not updated for a long time)http://www.angelfire.com/mech/sherman/. > And this one for the controllershttp://secure.oatleyelectronics.com/product_info.php?cPath=81&pro duct... > 6&osCsid=9d8ee84c2e2d01343bacd89272ce62a2 > > Will let you know how mine go when I get them, (mail takes 3-4 weeks > to get to me) > > Petewww.angelfire.com/mech/sherman > > > > > > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] > > On Behalf Of neroc > Sent: Thursday, 10 March 2011 18:19 > To: R/C Tank Combat > Subject: [TANKS] Re: speed controler kits > > Pete , here in the UK we are on the look out for reliable affordable > esc`s but i cant find the esc that you list, maybe its my computer but > it cant find the controller you quoted, and I cant get your > anglefire.com sherman link to work either. > > this is a shame because Im interested in both. > > Neil R > > On Mar 6, 2:00 pm, Pete <[email protected]> wrote: > > Frank, > > Thanks for that, I have just ordered my C6C (cant find my V1 in > > garage/mans land), and will be ordering my controllers shortly, and > > will let you know how it goes. > > > Pete > > > -----Original Message----- > > From: [email protected] > > [mailto:[email protected]] > > > On Behalf Of Frank Pittelli > > Sent: Sunday, 6 March 2011 02:35 > > To: [email protected] > > Subject: Re: [TANKS] speed controler kits > > > That looks like a decent reversible motor controller, which should > > be relatively easy to build.
