Thanks all, I'll definitely pass on this one

Looking to buy my first metal lathe and found this Heald 70 which the guy says is a lathe. All the information I have found, which isn't much, says Heald made boring machines not lathes. It looks to me like this particular machine can rotate the work piece or the tool so it's both? Can...

Seems to be plenty of bright folks on the forums here and I'm hoping someone can point me in the right direction. I have a couple crusty tricone bits, one has a cone with some slop, another has a cone that won't turn 360 degrees. How would one go about pulling the cones to gain access to the...

I appreciate the guidance. The bores are 3-5/8" and 3/4" , 3-5/8 looks common, 3/4 not so much. I'm just going to have to tear into it and see what I can figure out, I'm not going to pay $400 for a rebuild kit on general principle

I have a united states air compressor MK series that I am about to rebuild. I understand Collins equipment sell parts for them however their prices are extremely high. I am wondering if anyone has successfully located parts like piston rings, crank bearings , rod inserts by size rather than...

The tank and base are from an old Curtis compressor, if you look up 20s-30s Curtis compressors you will see an identical tank. The tank is very heavy duty, it weighs 3x what a newer tank of similar size would wiegh. That said I dont think I will be using the tank, when I opened the petcock it...

Your right, that is for sure a match, I appreciate it. On mine there is nothing connected to the centrifugal unloader, I assume that has been disabled in favor of a check valve? I'll have to get in touch with Collins Equipment and see if I can get parts, the compressor works reasonably well...

I believe the MK9281 is a serial number. I scraped some paint off and found the base of the pump has D-200 cast into it. D-# would be consistent with Curtis compressors. Anyone know anything about a Curtis D-200 ?

Attaching two pictures 1) a parts diagram for the United States Air Compressor MK series 2) a Picture of the head of the compressor in question Notice the connection between the two cylinders, on the MK series it is opposite of the air intake. In the picture of the compressor the connection...

Thanks, can't say I disagree but...the numbers dont match up to any info I have found on the MK series

I have tried to acknowledge the potential risk and redirect this thread to helping me figure out the make/model of the compressor. The compressor has been in use for roughly 75-80 years, it wasn't sitting in the corner of a barn rusting it was actively being used in a garage shop, I don't...

I appreciate the advice and plan on keeping my eye open for a tank...I would really appreciate someone trying to help me identify the compressor.

Here it is minus several pounds of dust and grime. I am not finding any info on the model mk-9281 , if any knows anything or can point me in the right direction please let me know.

The owner claimed it was all original and I have no reason to suspect he would be lying to me. A simple google search of antique curtis compressors showed multiple pictures of identical tanks on 30's- 40's Curtis compressors

Got it home, posting a few better pictures. I noticed one of the tank supports has "Curtis" stamped in it, the pump has a plaque that says "MK 9281".
