bradders Posted January 22, 2017 Author Report Share Posted January 22, 2017 Inbound for tomorrow morning "What's in the box"? A lathe chuck "Ok" Didn't realize I'd packed the Allen keys in my carry on, so the TSA now have a tool kit, as I could've undone something one the plane :-) Link to comment Share on other sites More sharing options...

bradders Posted January 27, 2017 Author Report Share Posted January 27, 2017 How are you getting on with the TBAS Mark? Pretty good so far thanks Installed the other day and already teaching myself. First jobs were a couple of .22 barrels and I'm very happy with the results All just a matter of chasing the circle Link to comment Share on other sites More sharing options...
JR FIREARMS Posted January 27, 2017 Report Share Posted January 27, 2017 Lathe porn! Good to hear. Are you making use of the angular adjustment for dialing the bore? Link to comment Share on other sites More sharing options...

JR FIREARMS Posted January 28, 2017 Report Share Posted January 28, 2017 Fair enough, I was just wondering as i know Paddy generally only uses the angular adjustment for truing actions. Link to comment Share on other sites More sharing options...
bradders Posted January 28, 2017 Author Report Share Posted January 28, 2017 The main benefit for me is with shorter barrels that can't be successfully mounted between chuck and spider. I don't generally chamber with a steady as I prefer to do it at the chuck, which is more cost effective unless you are truing a lot of actions. But as with anything it is a tool to be used when it has an advantage or is more convenient ETA: I did also get a set of their double pilot indicator rods for bore dialling, which are very nice :-) Link to comment Share on other sites More sharing options...
JR FIREARMS Posted January 28, 2017 Report Share Posted January 28, 2017 Fair point. It's nice to always have the options and tools to hand. It's better to have and not need, than need and not have lol. I forgot he does those. You certainly treated yourself! :-) Link to comment Share on other sites More sharing options...
nicklock Posted February 3, 2017 Report Share Posted February 3, 2017 Blimey, I think that chuck setup weighs more than my entire lathe... Link to comment Share on other sites More sharing options...
bradders Posted February 23, 2017 Author Report Share Posted February 23, 2017 A short vid to show the dialling in of a chamber using the Truebore Alignment System and dual bushing indicator rods.

MJR Posted February 24, 2017 Report Share Posted February 24, 2017 Did you find a significant time saving over other methods? And are you still using a spider on the outboard side? Link to comment Share on other sites More sharing options...
bradders Posted February 24, 2017 Author Report Share Posted February 24, 2017 There was a bit of initial 'chasing your tail' while getting used to it, however the more you do use it, the quicker it gets.For long barrels through the headstock I would still use the spider, if only to take the stress/weight and stop any potential for shift.However while doing shorter barrels through the headstock that aren't long enough to reach the spider, it's a vast improvement Link to comment Share on other sites More sharing options...
MJR Posted February 24, 2017 Report Share Posted February 24, 2017 Thanks. There's always a bit of a learning curve with something new, i'm sure it will get quicker with use. My only observation would be that the set up moves everything further away from the headstock bearings. What increase in length is there over a std chuck arrangement?

bradders Posted February 24, 2017 Author Report Share Posted February 24, 2017 About 2 3/4" I don't think the bearings would be a huge factor based on load, but time will tell......and bearings aren't particularly expensive anyway Link to comment Share on other sites More sharing options...
skunce Posted May 3, 2017 Report Share Posted May 3, 2017 I would like to thank bradders for taking time to do this write up on machining an AR barrel. It motivated me to machine up my first AR barrel that I chambered in 20 Practical. I closely followed your method and ended up with a properly functioning and accurate rifle. I've machined many bolt action barrels in the past and enjoyed the challenge of doing my first AR barrel. Your write up was very helpful and interesting.

Forlorn Hope Posted May 29, 2017 Report Share Posted May 29, 2017 Thanks for posting this, it's a fascinating insight. I had no idea how big barrel blanks were, what's the outside diameter? Link to comment Share on other sites More sharing options...
