Don,
Working fine here mate, i'm guessing probably something to do with your security settings, but best to have a word with Lincs_Sniper or DaveL on that one, i'm sure they'll get to the bottom of it for you.

Please don’t go knocking the uses of the guard, its bad enough Sam has to use that lathe.
After watching the demonstration myself, I shuddered at the noise that gearbox made as he turned a thread.
I take it your lathe is gear driven and not belt driven Sam.
The noise that gearbox made, reminded me of the Harrison L5 lathe, as noisy as they came, with its noisy gearbox.

great videos guys nice to see how its done.i know im always slagging off rapids .sam in no way am i slagging you or your work off.i just don t understand why theoben dont thread cut them in the factory as standard surely they must realize that most folk would rather have them screw cut to try different silencers. thanks again for the videos keep up the great work.

Verminshooter29,
Theoben do now offer their Rapids with screwcut barrels from the factory and have done for a short while, they do listen and catch on eventually.
Replay...
Bet those 2 Axminister lathes belonging to Colin and myself have turned out more quality, saleable airgun, shotgun, rimfire and fullbore components in the last 12 months than yours will do in a lifetime.
Most lathes are capable workhorses these days, its all down to the man stood behind it, which is probably where yours falls short.

Only having a friendly josh with another turner, good to see the video posted to show people how it's done, wish one of our customers had seen it, might have understood when I told him I couldn't re'm/c thread on the end off his 4ft long undercarriage leg that had last foot bent 45deg, mind you he also didn't understand when I told him it was m/c'd when straight and in softened state then bent, then hardened and tempered, he just walked off muttering about us getting newer machines.

Hehehe, yep, some people just don't apreciate how much work actually goes into some things. (should've shown dialling in with a 4-jaw and DTI for a barrel with eccentric bore!)
Watching somebody else do it in a video like this makes it look easy anyway, so most (non engineers) probably still won't fully appreciate the process...
I shortened, recrowned and screwcut a centerfire this morning and fitted a mod that i'd made from scratch, now that might've made interesting viewing from start to finish.
As for your customer, bulldog, tell him to get himself a BIG die set!

When playing with various barrels in my lathe I've found a simple way of doing this. I have a 3mm dia ground rod, dead straight, and made two 4.5mm PTFE sleeves to fit over it. A couple of wraps of insulating tape either side hold the sleeves in place while I push it down the barrel, the rod pokes out the end and a DTI can be used on it. If the choke is tight push the rod and one sleeve through from the back end and slide the sleeve onto the rod from muzzle end.
How do the professionals do it ? Come on, share the secrets !

Spot on basically.
You'll find the majority of modern barrels are much easier as the bore line runs, more often than not, concentric to the outside diameter.
If thats the case then simply dial in off the o/d of the barrel or blank and start making swarfe.
If I do get an eccentric bore then I have a range of bore pilots and will dial in off the pilot, simple really, but takes time.
I've had a delivery of barrel blanks this morning from a well known barrel maker, each and every one has been perfect.
(Boy do I wish that was the case with some of the old rimmies that come in)

This is so slow on the old type centre lathe-a CNC lathe with self centreing jaws would do this job in less than a minute if block tooling was used.Set up time would vary with operator but would be less than 1 hour.

Just watched this for the first time. My lathes are MUCH older than the one used, but would give better results as I would have the compound slide set at half the thread angle (the corect way to screw cut) to apply a cut, and would use a verdict gauge to clock up on the bore. Other than that, nice video.
Glasses are much better than the perspex guard, especially if coolant is being used.

Now, you say that and technicaly you are correct, I was trained to do that, but once out of the training school stopped doing it, 30+ years in the aerospace industry and I've not had a complaint yet (apart from cutting the threads a bit tight)
