Just a little video I made today... It's finally warm enough to start getting some work done in the shop...

I can't wait to get my new 11x26 lathe this year... the 1" Spindle Bore is going to come in soooo handy...

It's been decided that I am going to be farming out most of the grunt work and just do the finsh work in house... My hands and back are going to the crapper...

Hey! The best stuff comes from small garage shops!
There's only time for detail not volume. Cool

Mine is honestly true. Mr. Green

Joe - I really liked the video. I don't own a lathe, but your procedures (and the reasons for them) were absolutely clear, even to someone like me with little experience. Good job!

Thanks guys.

No matter how many of theses parts I make... I ask myself one question before I finish them... "Would I put this on my own gun?" If the answer is no... then it's not ready for an air gun buddy...

This was Take 4... I really hate to hear my own voice on tape.... Duh, studder, studder, pause, pause... Razz

I have a few more.... I just don't talk in them...

Fantestical Pete! Thank you!

I'm not even awake yet and I see the benifets... So I found a set on eBay that covers the full range and ordered them. Mr. Green

yer won't have to grip them on a machined / finished surface and risk putting jaw marks on them...

Thanks Pete!

I've been so busy I hadn't gotten a chance to fit those expandable arbors to the sizes I needed.... I'm down for a week... the sharpening service has most of my carbide cutting tools till next Monday...

So I took some time and fitted two of the arbors today using my index-able bits... and all I can say is "DAMN"... I got the best "off the lathe" finish on these friggin monster brakes for the Lamo Bull Barrels...

I put a taper at the chuck end of the arbors to make sure the work is dead center and turned down the rest to the ID size of the brake.

Using the arbors also dampens the harmonics of hollow pieces and gives a much smoother finish.

No touch up sanding at all...
