small lathe bores/cleans up holes to fit steel tubes , then

braze with dbl headed torch .

Its the best technology for airplanes .

So why not use it ?


MIG the lugs then grind them and bore them .
you can CRS them , work harden them .
100,000 psi steel tubes , brazed into lugs .



Its the lightest .strongest .

Even when you're short , as Reynolds
bicycles was in WW II , for Crome ,
the tubes were still very strong
w/o that crome .

BTW Dont buy welders from www.longevity-inc.com

I paid $650 for model 518 , heavy heatsink is the only
thing fastened to fragile transistor legs . They break off .

Also , 2 relays handle 90 amps each , instead of a large
front panel switch , as others do .

Simon K does not like to talk tech about his welders ,
he knows their junk .
