Bernie,

the standard 3 jaw chuck for a Taig has soft jaws. You can easily turn steps on those with your lathe. For accuracy you have to true them on the spindle. You might have done that when you first assembled the lathe. The 3 jaw chuck comes with a washer specially for this purpose. There is information on the web on how to machine steps on your soft jaws. I did it for mine (actually I bought an extry set of jaws, they are cheap enough).

Thanks again. Ren I watched the video and it answered a lot of my questions. Bob thanks for the info. Jan I did true up my jaws when I got the lathe. I took probably a lot more time than it should have but it is pretty much dead on. I am still doing some research and will study some more videos. Thank you all again for your help. I probably should have did a lot more of this back when but I could always send it out and have it done. Have a slew of caps and barrels to practice with. I just didn’t want to practice on Becker’s or these older clocks.

Hey Bernie, thought I would throw this at yah too. I have not done this but I have read it somewhere. What about using a chunk of wood. If you have a faceplate, OR use your wood lathe to turn a small diameter knob on the end of the chunk of wood for your 3 jaw. Mount it on your taig and use that to turn out a recess in the wood for your barrel, it should be concentric to your headstock, if thats what you call it, just big enough in diameter so you have to press it into the wood recess, or at least hold it enough for boring. I imagine that you would want to bore the cap with the barrel by putting the 2 together and fitting it all into whatever your going to hold it with. Not sure if this would end up being a one off set up but if you start with the smallest diameter first you could adjust to do all 3 barrels for a one clock. just me thinking this mourning 🙄 , William

Great thoughts William. Will have to ponder that for sure. Would have to have one for each barrel because these are very different sizes but I think would work rather well in a one of.

That is a great video Chris!
Thanks,

Here we are attempting to do everything carefully, whilst the creators are just throwing them together, kinda burst my bubble, like someone telling me that Santa doesn’t exist 🙄

Can you imagine sorting jewels all day, every day or drilling the same holes, or being a screw polisher! I’d go INSANERER 😆

I wonder if the little Elgin honeys in the jeweling department ever made a calender, 1950’s style 😈

Yes, I think it’s a combination of factors, including…. respect for the item, need to preserve certain extinct parts, lack of knowledge and ALL of the correct tools, lack of constant experience etc etc

These guys were doing this one task 8-10 hours a day for years, they could do it in their sleep probably, I shudder to think that I have to go and count, hole size and sort a million jewels again today Can I get a transfer to the screw polishing department 😆
Oh yeah, and did you notice the “old style” supervisor walking up and down the isles? No chance of fluffing off or having a chat, your world is a 1 inch diameter peep hole..
At least we can throw on some tunes, crack a beer, have a cig…..Luxury

Well today I bought a dial indicator with 22 different indicator points, found a set of 80 carbide bits from 80 up, and a Taig 4 jaw chuck. So should be good to go. If I like the dial indicator I will probably order a second one. Can’t go wrong for $27. The bits ran me $81 and the chuck $75. Thanks for all the info and help guys. I appreciate it.

Bernie you’re making out like a bandit, that’s a pretty nice haul for a decent price. Here, in beautiful downtown espana, they’d charge you that much just for looking *rip off*, s’cuse me, I have a cold 😆

Have you set it up yet and successfully zeroed in your work, I know you have

Not yet Chris. They will be delivered on Monday and Tuesday. It will be interesting to see how the carbide bits work as I have a couple of seth thomas wheels to repivot. Also have 4 or 5 hermle barrels where I just replaced them with new ones that I can practice on putting bushings in with the new chuck. So going to have some learning time. Here are some pic’s of what I got.

Bernie, I’ve been looking at the same carbide set, you’ll have to lemme know how you find them, please

Again, I’m probably preaching to the choir, but these carbide bits, while they will cut through anything, also tend to break like pretzels, very easily, I broke three on the same job a while back 😥 ten cuidado hermano mio va lentamente 😆

I know Chris. You have to be careful and don’t put a lot of pressure on. To me most times they break when trying to muscle them thru the cut. If you break them off inside the arbor you are up creek without a paddle. 😆 I will let you know how they work out.

I posted a while back about a oil clutch kinda gubbins to avoid breakage with these drills, basically a piece of drill rod with a hole drilled to a snug sliding fit on the drill bit apply a fairly think oil and use this to hold the drills when drilling, if you’re drill snags it’ll harmlessly spin in the rod rather than break in your job, if you do break inside a hole the carbide is brittle enough to shatter so a bit of tender hammer and punch work can sometimes break them up enough to be able to remove them,

I have a self centring four jaw chuck, works on the same principles as the three jaw scroll chuck, I do have soft jaws with steps turned on them for boring out barrels and wheels
