Well I got the tubing set I ordered from Novacycles.com it is a basic Dedaccia Crmo OS package with lugs and bottom bracket. I think it is a perfect blend of price and set up for a beginning builder... meaning if I screw it up it won't hurt so bad in the wallet.
After ogling the tubes and lugs I decided to get started on boring out the lugs to fit the tubes with the recommended "slopy fit". After eating my lunch sitting on the garage steps and thinking about all the things that could go wrong here... I took a few deep breaths and got started.
in the photo's you will see the lugs clamped in the vice, I used a dremel to grind out the sockets (typically needed to take off about .001 of an inch to make the tubes even enter the socket. The 1st lug (the lower head lug) took me about 1.5 hours just to grind out enough to fit the tube with the slightly sloppy fit. I learned qucikly how easy it is to snag or spin the grinder outside of the working area on the lug (see the two grind marks on the point in the vice).
The next lug was the top tube/head lug and I tried a couple different bits on the dremel and found that the sand paper bit works best for removing more material (but the stone shoots lots of sparks for the dramatic effect) it only took me about an hour on this one.
Not pictured is the seat lug and bottom bracket, I ended up doing them on Sunday evening and was able to bore and finish the outsides in under 2 hours.
I think everything fits pretty well and I have the right "sloppy fit" I need for silver brazing. Tonight I will start mittering the tubes which I think will be a more tedious process but we will see.
