| Subject: | More files from the Galacticly inept Piet builder |
To paraphrase Forest Gump, I'm not a smart man...but I know where to find advice
from Tony Bingellis...
The photo below show my progress attempting to make the center section "U" fitting.
I made some progress from A to B to C.
Just like the public defender said in the movie "My Cousin Vinnie"... I'm getting
better...
A is my first attempt without the guidance of Tony.
B is my seconds attempt AFTER reading page 48 and 49 of the Yellow Bingellis book.
One of the two bends has too little radius.
C is a decent fitting needing more polishing of the edges with some 200 grit sandpaper.
I'm trying to get all these pieces ready for 'Tools' Toolapalooza 2014 coming up
Feb 20-24 in GA. I'm going to see about getting some welding experience on
some scraps of 4130 and if I'm lucky get these fitting done that weekend.

Yeah, I'd expect about as much since most people have figured out that
you're the same Jim Hyde that came onto the list and threw a hissy fit
about our generous hosting provider, Matt Dralle.
I haven't been watching the list very closely, but I haven't seen or
heard of any sort of formal apology for that tirade. My guess is that
we're not going to see one, but I'd be happy to be proven wrong.
