I stole Greg's(RCLogger) carpet rail idea for the track pads so I can't take any credit there, the only thing I did differently was weld nuts to the links instead of using K1 type chain. I've done a little more work to it in the last few days so when I take some more pictures I'll post them up. As far as my TIG skills... just when I think that I'm getting better someone lets a seagull into the shop

but thanks for the vote of confidence! I've put in a few 8-9 hour days on it in the last 2 weeks so it has been coming along quickly.
Thanks
