Re: re vac forming

Mario,

I looked in Don Ross's newest book "Flying Models Rubber, CO2, Electric, &
Micro Radio" and he has some pictures and explanation about a vacuum forming
machine / kit made by Douglas E. Walsh, 272 Morganhill Rd., Lake orion, MI
48360. Looks like a very nice setup and it can be gotten as a 2 stage unit.
I searched for a number on the ATT web site and got what looks to be a
direct match with a phone number of 248 391 8290.

Hope it helps,

Tim
[Denver, CO]
