The tires came from a Maitso diecast notchback, but they were a little skinny, so I widened them.  I had to cast the tires in resin so that I could widen them and then had to recast then back into rubber (I use a product from Reynolds called Task 14 and it comes out more "rubbery" than most kit tires). In order to get them done, i had to cast two separate molds (the first to make it in resin and then the second for the master). The original mold had he tires set in a plug that I can use to chuck-up in the lathe and machine the tire and separate each half.  It wasn't until i was too deep into it that i realized I should have cast three molds (two for the resin tire since it is directional). Here are pics of the masters once I widened (the center is just some type of butyrate plastic I had bought from Small Parts, Inc. and machined to the proper ID and OD:

Here are masters for the censors of the Fuchs wheels that I also got from the Maitso diecast:

And then the wheels (machined outer and inner sleeves, with cast centers) and cast tires:

I'll try taking some pics later of the resin plug I used for one of the tires and also put the originals next to the new ones for comparative purpose.

I love the idea of the center's being the classic Fuch's design yet modernized with low profile tire's and wider barell's...going to fit the look perfect.  Should be pretty cool to see these two style's mixed and I think your going to do it justice.  I never really thought about machining plastic pipe to the correct diameter for wheel's....not in a precise way such as a lathe or home made dremel drill lathe thing like I am going to try.  Keep up the good work

Thanks, Gents!!! I really appreciate the kind words!

I can't find one of the resin plugs I used to make e tires, but I do have one of another tire I did. In the pictures, you will see what seems to be a plug and that is pretty much what it is. I basically machined a plug so that I could slide the tire onto, then once I pulled the resin out, it gave me material to clamp in the three-jaw chuck, in the lathe. Despite my best efforts to have the tire on the plug and trued, it still wobbled once I took it out of the mold. What I didn't realize until later, is that I could chuck in with the tire in the chuck, true the plug part and then reverse it back to machine it. The other thing I realized is that the tires aren't perfectly round either, so once you have the pieces to glue and piece the tire back together for the master, I couldn't get it exactly now I wanted it (good enough for gov't work, though):

Here are pictures of e upper and lower control/A-arms mounted:

The aluminum tube in the last picture is to set the proper distance between the arm attachment points. Then a pin is slid through the two brass pieces, as well as the aluminum piece and should be pretty straight and makes soldering a little easier.

The way it was supposed to sit:

LOL! Not really, Bill. A lot of this has been done in the last month or so, just haven't been able to get to posting pics.
