Drill press upgrades

markfrazier16137@...
 

Now , before some ya-hoo jumps on me about off topic and not lathe related. I made the aluminum collar for this project on my South Bend 9 inch lathe. I am posting this because it is possible that someone else might be interested in this and ALSO, I am incorporating this same idea to a DRO for my South Bend lathe tail stock but it will be easily removable. Now down to business.


 I wanted to share with you the drill press upgrades I made for about $15 that is money well spent. The first upgrade is a knob upgrade. The wimpy little knobs that came on the drill press were hard on my old arthritic hands. I ordered the nice big red knobs from McMaster Car for about $ 8. The next upgrade was a DRO made out of a 4 inch digital caliper. I do a lot of set depth hole drilling and this is so much more accurate than what came on the drill press. I bought the caliper at Harbor Freight on sale for $6. I found you can’t drill them ( very hard) so I used my Dremel with a cut off wheel and cut off all the points and about a half inch of the rear tang on the sliding piece. I then used a carbide burr in the Dremel and ground two notches for the anchor points. The two nuts on the one screw let me adjust the anchor point for a nice smooth operation. I made the aluminum collar on my lathe. I am going to use this same idea to put a DRO on my lathe tail stock but it will be easily removable. If you have any questions let me know. The photos are in my projects folder.

Thanks for the follow up on Ed. Life is so short and we never when it going to come. It's not like the commercial on TV, "Your will have a heart attack tomorrow". Our prayers will go up for him and his family. 
Again Thanks

Ed had gone into the hospital around June 1 for a triple bypass. While in there he suffered some strokes.
He was released toward the end of June and went home and to therapy.
 
Around July 2 he had an onset of Crohn’s disease. He developed Pneumonia. and was put into an Induced coma. He had to be put on kidney dialysis for several days. (The kidneys are ok now)  However the Crohn’s is causing a lot of issues.
Ed has lost 30 pounds and has been in the ICU until last Saturday.
He was transferred to Regency Hospital Acute Care.
He is, however slowly recovering.
 
Now if you want you may send cards to his home and his wife will bring them to him.

Do not eliminate the possibility of worn out motor bushings.  Things do change as they warm up.

 

With the cost of labor, most motor shops do not deal with small motors.  Our throw away society.

Thank you everyone,

Didn't at the time think of "ALL CAPS" as shouting but I do see your points. I believe my mind set at that moment was an imperative plea for help. The motor is a 110/220 vac motor wired to run on 110. Having reviewed your comments and help I would like to say no the bull gear is not engaged, the motors armature spins freely even though it has plain bearings w/oil cups. The counter shaft and lathe spindle both rotate freely even after running for a long time. The belt(s) do seem to be slipping and this slow down occurs within seconds of starting the cut (10-12). So everything being said I would once again like to thank everyone for their time and help. I will address the capacitor issue via a motor shop in the immediate future.

Sincerely,

Steve Karvelis

The PIN in the bull gear SHOULD be engaged in the cone pulley.

You didn’t give the motor voltage.

Is it 220Volts?

If you have a bad connection it may be running on 110V?

 

Any large drag, like a defective bushing” would cause the motor to overheat.

 

We are going to need some more information to be of much help.

Thanks

Rick

Also consider moving the right end leadscrew support and gearbox or left end support, or see which fits the best. South Bend did more precise fitting on the lathes with power feed and with gearboxes than on the plain lathes.

The right end leadscrew supports and taper attachment bed clamps were fitted in place by pouring Babbitt into the cast iron piece around the end of the leadscrew and the rod that connects to the attachment.

I'd look at a stretched or slipping belt

More belt tension, or belt dressing in a spray can can be helpful

then I'd try testing the capacitors

If the pulley is loose on the motor shaft belt tension can keep them

I had a similar issue some time ago and I found the take up nut that controls the axial play on the spindle was too tight and after running a bit it would heat up the rear journal. The expansion caused even mot tightening and eventually it would lock up?
