Bushing a plate bearing for barrel arbors

Rich, whats going on with your tool rest? That missing chunk would drive me nuts! Good turning though!

[Neverenoughwatches]

I didn't have any brass bar....so a two pence piece provided me with some material to make a mild bronze bush. Hopefully i have enough diameter left when its rounded up.

It bloody well is just now, the previous owner cut two slots in it , god knows why . Dont ask why i have it back to front, its just giving me a better tool height to get in close....it might actually not be for this lathe.

Its not big enough and it looks way too coppery to be as durable as bronze. Nice little practise though, I don't think I've ever seen anyone on youtube turn a cylinder the right way, all the ones I've  watched in the past use the whole of the cutting edge held flat on the rest instead of running off meat from the middle of the cylinder using just the center of the cutting edge..nice to see the shavings curl off, yesterday really peed me off lol.

Slightly off topic: What make collets do you have Rich? I have several of those marked with the 2 c's and a code 2807 as well, but I don't know who made them. Do you?

My lathe is a Wolf Jahn it came with mostly all of the cc collets also with the 2807 code. There were a few wj with it.  So my lathe wasn't something just floating around Ebay, i picked it up from Leeds, the seller's past father was a watchmaker and his grandfather as well. I turned up at his father's home as the seller was clearing out his old man's possessions before he put his house on the market. The old boy had a full watchmaker's and jeweller's workshop in his converted garage. If i had known i would have taken a big wad of cash with me and bought the lot. So my lathe either belonged to an 80year old watchmaker or a 100 year old watchmaker....so i figure the collets are correct.  The only lathe collets that are an exact match for the WJ that i know of are Bergeon and Hinchcliffe. So the cc could be from the two C s in Hinchcliffe .......possibly? 

8mm that is.

Anyone know if this is a lathe graver ?

[AndyGSi]

It looks like a graver but can't quite make out the working.

[nevenbekriev]

Yes, it is for balance (type) pivots. The tip is rounded by design.

It is held on the T-rest this surface up

Thanks Andy, this one has Glardon stamped on it with a little fish symbol

Thanks Nev,It has a nice round edge on the base that glides on the rest.

Thanks guys, I also found a chunky graver that I sharpened up, I think its carbide.....just reduced the shaft of this carbide drill to fit in the drilling sleeve  of my lathe, it cut it like butter as it did also some blue steel.

Lol yes I have Case, this time around it has unleashed the turning beast in me .....soon be time to have a go at my first balance staff......after I've aquired some brass material to finish off this project that is .

Morning Case , I've just seen some cc collets...listed as Crawford

Thnx. I've never heard the name Crawford in relation to watchmaking tools.

I have several lathes at this moment and am figuring out what to keep and what to part with.

To help make that decision I'm making a list of which collet I have fits which lathe. My Wiskum lathe came with 1 Leinen Collet, 2 WJ and 16 CC 2807 marked collets. With 1 or 2 exceptions, most of those also fit in the headstock of my Boley-Leinen and Wolf Jahn lathes. A few also fit the 8mm Lorch. Recently I was fortunate enough to find a small mixed batch of collets (lorch, wolf jahn, bergeon, SA (?) and cc). There are some small variations in length and thread pitch, but I figure I can easily make additional drawbars if I need to. The tapers look identical or close enough so I guess/hope that won't be a problem.

Crawford is correct for the cc collets, I've heard it before .  De Carle's lathe book list most brands and the differences between the collets, when i get home i will post that page

Ah ok, that collet list is not far into the book, it should answer some questions you might have .

I believe they are all b8 collets, but with some differences?

I'll do a search for the b8 standard and see if the taper is standardized..

I did have a seller once tell me that all the tapers are the same. The taper and keyway would be the important bits for the same millimetre collets leaving just the drawbar to be matched up. Looking at this list the taper is not specified so they might all be the same.

Though De Carle states this ! 

Coincidentally i have 5 internal step chucks for an IME lathe, so i need to think about making a drawbar for them.

I'll press one in a piece of clay and use that to check the taper angle and get back to you on this.

There's a few besides that i think we might get away with.... same pitch thread but 2 microns under in diameter Boley and leinen is so very close for fitting the wolf drawbar.

Play-doh tells me the taper angles match on WJ, Bergeon, SA, Lorch, Leinen and Crawford.

There are indeed some small thread variations, so there's no 100% match on that but the wj drawbar fits most of them.

Great to know this Case. I'm in a dilemma to buy these collets for my Boley and Leinen A2 . I've talked the seller into letting me buy just one to see if they fit. Its a lot of money for the set....almost double what i paid for the lathe, there is no drawbar so i need to arrange that. But so so tempted, just cant decide if their usefulness will be worth the outlay or if i can find another option that will do the job as well....i keep looking at the big ER colllets to see if I can make them work.

We've gone off topic a little here ,but since i started this thread i assume if I'm happy about it then thats ok.  A couple of hours got me this,  future watchroom tidied up and the big lathe carted upstairs and installed with a temporary set up. Another half hour to get an old florry light put up.

Jealous of that lathe, but the table looks about to sag at the knees!

Its a lovely lathe......haha the table is very deceptive...the legs aren't wood... its a fully welded box steel one piece frame ...more than boss of the job...but still a tiny wobble under the 80 odd KG load of the lathe and motor.

Ha....Just figured out what the notches in my lathe rest are for....possibly.....but what I'm using them for. Sharpening a graver with a diamond wheel in the lathe...the lathe came with a number of accessories, burrs and the like and a small diamond wheel. These bend easily when pushing the graver upto grind...the notch act as a stabiliser....not in the case I show, as the wheel is two sided . But in the case of a one sided wheel it will apply, may not be exactly on the nose but i think its on those lines with my lathe.
