    Incompatible DRO Scales?

    I am putting a DRO on my 2nd milling machine and ran into a bit of an issue. The scales are not able to be read by my new DRO. The new DRO does read the scales on my other milling machine, so I believe there is no issue with it. My old DRO will not read the new scales either. I have tried...

    Just a home hobbyist looking for carbides.

    I'm struggling a little bit in finding several carbide inserts for my machines. Application is just general purpose around the shop. I have been looking the carbide charts up and down, and have a handle on the shapes and angles, but the size and other variables escape me. Anyway, 1st on the...

    Finally bought a J Head Bridgeport!

    I have been casually brousing the forum on and off for a while, but now I need to get specific and serious with my research.:D I picked up this mill at the estate sale of my wife's uncle, but he never had gotten around to setting this up and running it. As luck would have it, I did speak...

    Lathe jaw pads for holding hydraulic valve spool.

    I am going to attempt to convert this two way valve spool to a 3 way operation by machining the undercut area one one of these spools. I have to make sure that I do not mar the surface in any way, and wonder what the best method would be for chucking it in my lathe? Brass shim stock? Aluminum...

    2x72 Belt Grinder Belt/Motor Speed

    Hello all, I am build a 2x72 belt grinder using a DC treadmill motor. The 1.5 hp motor I have is rated at 90V on the tag. No RPM is given. I am driving it with an 120V SCR speed control fed through a bridge rectifier. I get a maximum of 108V at present. This gives me a motor speed of 6700...

    Help with some information on a "compact" milling machine?

    This may be an exercise in futility, but what the heck... So my dad calls me and tells me about this milling machine he saw in a local classified ad. Mill is in Grand Junction Co, and dad is in Moab, UT a few hour away. He went to see it and talked to the guy - an established machinery...

    Good source for Tesa cutterhead blades - Inca 570 Planer/Jointer

    It has been quite a while since I bought any replacement blades for my Planer, and I wondered if anyone here knows of a good(cheap) source for HSS or carbon blades. The ones I would need are 260mm in length. Tersa is the brand name, but I would be open to aftermarket sources also. Thanks

    Disassembling a LeBlond quick change box

    Not quite sure how to get this the rest of the way apart. The nuts on the right and left don't seem to do anything obvious. But I am sure they are there for a reason. I am assuming that I need to fabricate a wrench of sorts that will index into these two rectangular holes. Then i can...

    Replaceing a motor starting capacitor in a 1hp single phase motor.

    I am rebuilding the 1hp Dayton motor on my 1917 SB, and want to replace the capacitor. Is is a 540-648 uf 110v capacitor. I can find one of those, but the capacitance range was a little surprising to me. I am used to seeing specific values, not a range. But, I can more easily find a...

    Rockwell 25-700

    While i was in the barn taking some pics of my current project, I snapped a few of my other lathe. I have serial # 1297478. Wonder how old it is? I am in my early 40's and My dad had it in his shop at his coal mine when I was just a boy. Years later, I was able to acquire it.

    Restoring my 1917 Southbent O Series.

    Restoring my 1917 Southbend O Series. I recently had the opportunity to acquire this lathe for free.:D It was stored at my work and we where moving out of the location and I hated to see it just discarded or left behind. I was sort of indifferent about it, until the drive home. The more I...

    Help identify an old Leblond, or Southbend.
