very good job
Thank you! I appreciate the feedback!
Looks great. Liked and shared. All my best.
Thank you so much! It is appreciated!
Excellent job man, looks great...
Thank you!
That shaft turned out really nice. I have a mixture of conventional and cnc machines and I love them all. I would do my taper shaft keyways exactly the same as you did because thats what the clutch told you to do.
Thanks for the video.
Thanks for watching! I’ve worked in CNC and Manual environments, and of course my shop now is all manual.
What kind of work do you do with your machines?
The way you did the woodruff key seat works, as would doing it along the axis of the shaft, the end result is identical if both are done properly
Nice job! I have a milling attachement for my lathe but found it's super flimsy and likes to come loose.. I'll use it if I really have to but I got a mill and that's much safer
Thanks for the comment. I have a Bridgeport Series 1 and other machines, but I decided to do this just for fun on my small lathe using this milling attachment. I agree that they are a last resort of sorts for milling, although there are a few neat things you can do with them. Thanks for watching!
And I agree that both orientations of doing the keyseat would come out ok. I just like doing it the way I showed.
@@MaineMachinist I have the same milling machine, my lathe is just an old Advance 14x40.. I'd be a lot more comfortable with the milling attachment if it had a better locking system for the angle rather than tightening the pivot nut.. something more like the locks on a compound.. real easy to break cutters and parts when it moves on you.. Even if the nut had a left hand thread it would be an improvement
@@Rx7man I also have the much larger and beefier Palmgren 400. You could probably use that on the 14x40 because it fits well on my larger Logan 6560 machine. I have a video comparing the sizes of the two milling attachments and the features of the 400
Part turned out great. Nice to see vintage machinery being put to use. Do you have much wear in the bed ways that you need to compensate when cutting a long shaft diameter?
On this particular machine it actually turns a long diameter very very well. The machine has some wear but is remarkably accurate. On my larger Logan lathe I have a lot of wear near the spindle. I did a video showing ways of checking a bed for wear with that lathe shown since it was a good demonstration. On that machine I have to compensate. I usually take a test cut and measure, and make some marks along the piece with a sharpie, then use the compound set at 29.5 to feed very gently in as I go along. Emory cloth for the final finish to blend it nicely.
Shaft turned out great! Love that you did it old school. What metal did you make the shaft out of? 4140 or?
Looking at the chips coming off I am going to guess 1144 stressproof?
It was actually 1045 TGP
There was a piece leftover from a previous job and we figured it would work fine for this application and save the customer some money.
On a side note, VW Purist, I have one more video tomorrow to upload that’s tractor related and then we’ll be digging into some Air Cooled content again. Thanks for watching
