In his defense that stupid app turns sigs back on after updates sometimes.  I always have to remember to check.

Looking more and more like a bike  

so .... last post was 15 Ap17; how'd it turn out; assuming your riding now?

.... spiffy shop you have there; looking out your log house, hardwood floor, living room window; my wife wouldn't let me work on my bike in the living room ....

Metal in the frame; do you know exactly what it is?...was just looking up duc frame metal spec; is it 4130 cromoly? or E420M UNI 10296-1. shorthand for alloy steel, or 450 which is a factory's designation for a particularly complicated alloy ...

ALS450, arguably chrome molly, but a far cry from the 4130 used on racing bicycles and some Verlicchi frames used on some special edition high performance Ducati trellis frames (think TT2 for example).  ALS has chrome molly content, but little enough to still cut and weld like mild steel.

right confirmed what Iv been learning, thanks. From what I've learned corme moly is 90,000 strength; 40 k stronger than the ALS 450, 50k; but somewhat more brittle; so for a road moto frame crome-moly doesn't work as well .  CM wouldn't flex and more brittle. The 450 would be a European designation (?). Cromoly is also harder to weld and would more expensive, thinner, lighter due to strength ...

That's a friends house. He and we, his 'friends', have converted one of his three living rooms into a work place/man cave. The rest of the house is occupied by old and/or grumpy hunting dogs and decorated with weapons and whisky. He's single and expects to stay single 

The bike is finished and runs great. Suspension better than ever, new T-drive discs, painted plastics. The harness is old and probably next on the to-do list. I now have another couple of things to fix or hide after a 350 feet slide on a wet track day - lost the front wheel when braking from 110 mph. 

I can't remember anything of what I found here while researching frame material, but I had the frame welded twice last year with good results. I believe the welder did it as if it was 'ordinary' steel...
