clearance on my 10f

There is something funny going on with my atlas.? when the top slide is inline with the cross slide the handles interfere with each other.? All the round handles are 4" in diameter so i havent put the wrong handle on as i have been rebuilding it.?
?
All that is different is i put a different micrometer collar on that hasnt altered the length of anything.? even if it did it would still collide at a different spot.
?

开云体育The handle that you have on the compound is the one that belongs on the cross slide. ?The compound should have a similar handle except that it would be smaller and with two handles instead of the one. ?No idea where that extra handwheel came from.On Feb 1, 2025, at 7:57 AM, hedgesben via groups.io <hedgesben@...> wrote:

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. |

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.? |
