True Bore Alignment System

[urbanrifleman]

I think I'm going to buy one of these Truebore alignment systems. I have a Gator six jaw Chuck that I think is the one that goes with it. I don't know about chucks and what fits what.

I'm pretty sure my Standard Modern 1334 and my Acer 1440 take the same chuck size. But I honestly don't know that much about parts and machines.

I've tried to call the company that makes the True Bore and their voicemail is full. I sent an email I'll see if I hear back.

Does anyone know of a dealer that sells this other than the guy that makes them? Or a similar alternative?

You might want to watch the video below. He didn't think the 1440 machines had enough mass to use the TBAS.

The manual for it lists the chucks that fit. I like the idea of it... but I've heard too many people say it needs a hefty machine.

Also, any tapered sections of barrel (muzzle end) create an interesting problem.

I have one. Ive used it on both my grizzly 14x40 (1500lb single phase) and my victor 16x60 machine (3500lb 3 phase. Works well in both, some people complain about trying to part of with one in a lighter machine and getting chatter, ive never had that issue not that I part off on barrels that much but i use a thin HSS blade at a slow speed when I do. never a problem.

I have one, it runs great on the 16” Victor. I can run it on the 1340GT as well, but the speed and feed when parting has to be dialed in and a HSS blade used or it will chatter a little. I have never experienced any issues turning, threading, boring, or chambering on the little lathe though. I made aluminum sleeves with a slit to fit the barrel contours on the Mazek, I just put a screwdriver in the slit, spread it, and slide it back and turn it loose. I dont use it all the time, but it is nice when truing a 700 action.

Put the live center in the bore while parting?

I like the theory behind it, and think it would be handy in some instances, but I don't think I'd ever buy one.
Two reasons:
1) barrel whip of the unsupported end when turning at speeds over 1000rpm could be terrible.
2) holding on the muzzle end of a barrel to cut the crown/threads/sight tenon, is not feasible without profiled soft jaws.

I guess you could, I find myself cutting to length with the bandsaw and rarely use a parting blade anyway. I sometimes cut a relief groove with one, but not often.

I rarely part at the tenon.

 

[cb186]

I part the tenon "coin" off after I have indicated the barrel, as I want to see how straight the barrel is, before cutting the end off.
700rpm, .004"/rev, 1/8" carbide parting tool.

Well, I was pretty serious about buying one but if I can't get the guy to return my phone calls I'm not sure I want to waste my time.

As a Machinist, I think this system is a good example of a asinine solution to a common problem, that being how to true a barrel for chambering. In particular, in a lathe with a long headstock.

True, it is innovative. But telling people…..”this is great, except due to the excessive overhang and out of balance condition, you might have to spend $20,000 on a lathe upgrade”.

There are many more options in barrel set up that are simple, far less

expensive, and works on the machines that multitudes of Gunsmiths already have.

asinine solution

Asinine solution? Hmmm. Are you sure that is what you meant to say?

You say this is "asinine"?

 

[urbanrifleman]

I do find it a bit funny that everyone has been scrambling to find these tiny headstock machines, and with on Youtube video, that is all out the window... Now you can get a MONSTER!!!!

I spoke to Gordy this morning trying to find a way to contact that Nate guy. Still no ideas!!

 

[LVLAaron]

He's a small business. I emailed him a while back about something and got a quick reply... give it a few days. What's your actual question, if that chuck will work on it?

The max chuck diameter is 6.3 inches.

I think both of my lathes take the same size Chuck a D5? And the Gator six jaw has three connectors on the back.

D1-5.

The spindle on your lathe will have 6 cam holes... some chucks only use 3 (every other hole) -

??? It's an adjective so what's the problem?

Personally I'd give a lot of consideration to what this man says. If you've already made up your mind about it I don't know why you even started a thread.

When the negatives outweigh the benefits, yes.

But if it offends, I will substitute impractical.
