Neil, cool old saw! Sold my Super Rex back to Rick Helsel and he's got it running again, says it quite a beast!
I think i have seen pics of that Helsel super, never knew it was yours...
This one i will be demonstrating during lunch break at the home town of the original owner, it has gathered some interest already and may well be the start of more ''show and tell'' stuff at our future race meets.
I sent him the pics and he was totaly delighted to see it restored and can't wait to see it cut a block off.
I'm keeping it as it was used ie, solid bar and 1/2 inch chain but i may modify a bar by shortening it for simplicity.
