Re: countershaft bearings

 

@Bill in OKC too.... my friend is a model engineer and through him i know of a couple of others but its a dying art? mainly because here is no engineering in the uk anymore.? In fact everyone is getting sick of me saying that if i win the lottery ill visit the states and raid all the garage and estate sales


Re: countershaft bearings

 

On another forum (Home shop machinist) it was suggested that "caster bearings" may work for the countershaft.

Re: countershaft bearings

 

With a little help you should be able to build a new countershaft. Which, of course, would be easier if you have access to a second lathe. I get the impression that model engineers are pretty common there, though that could just be my selection of reading material...

Would it be reasonable to ask of local acquaintances if someone? could make a new modified countershaft for you? Or are you the only person you know with a lathe??

Re: countershaft bearings

 

That's why I suggested OP call Clausing. They will know what the OEM part numbers are. Though since he lives in the UK, Tony might know at lathes.co.uk there have been a couple of authorized copies.

Once you identify the Atlas part number, Clausing can tell you what is the manufacturer's SKU or part number, then you can cross reference to 21st century parts that are currently available.

Pain in the butt, but it is better than a non-working machine.?

Once you have part numbers you can order from anyone, anywhere. I am sure they have bearing shops in the UK. I was able to find such places in Turkey, Saudi Arabia, and Germany when I was in those countries.?

I wouldn't be surprised to find the correct bearings are obsolete. But there should be cross-reference charts that will help you find the the new versions.??

You're in the UK , so this should be familiar to you: https://www.lathes.co.uk/atlas/page12.html

It mentions that the Craftsman lathes (also made by Atlas) used oilite bearings rather that the cage bearing. Might find some parts info if you talk to Tony

Re: countershaft bearings

 

Another option is to modify it to take a readily available bearing as seen here:

I think I'd call Clausing and see if they have the parts, or at least modern part numbers.?

Re: clearance on my 10f

 

I have the ?same arrangement my 12" Craftsman 101.07403 standard change gear lathe. ?My compound handle got broken for reasons I'd rather not discuss right now. ?This feed screw now has the larger cross feed handle.?
?
For me, its SOP to always have the compound set at 90* from the cross slide, parallel to the ways. ?With the carriage clamped for taking facing cuts, I can easily take a precise amount off by advancing the compound using the graduated index collar.
?
For threading, my SOP is to also have the compound set as above. ?The first few passes are taken with the tool directly plunged into the work. ?Subsequent passes (for right hand threads) are taken with the compound advanced a few thousandths and the cross slide again plunged to increase the thread depth. ?For left hand threads, retract the compound. ?
?
Proceed in this manner with advance and plunge until the required thread depth is obtained.
?
?The advantage of this method is you're still putting most of the cutting on the tool bit's leading edge, but there's no confusing calculating to allow for the compound's 29.5* offset. ?(As if you could really set the compound to exactly 29.5*)?
?
I first read about this setup in one of the British model engineering magazines, and after trying it, I won't do it any other way.?


Re: clearance on my 10f

J Martin is right. Until you can get the correct handle, you may be able to eliminate the interference by setting the compound for 29 1/2 degrees, as you would for threading.

thanks for that.? the handles i have are what the lathe came with although they have been changed at some point in its life as some of the handles are picadore (a british make) Looks like ill have to try and find a new handle.? ?
