Someone with a CNC mill locally can mill your table top flat leaving a very nice finish on it. It won't be ground, but they can make it look pretty with the right facemill.

If you do get the top reground or planed, the table top is very thin, person has to be very careful how you support the top. It will require shimming underneath the table top to keep it from dipping down when going across it with a tool that is removing metal. Rather you grind it or plane it, the pr...

Yeah, I bet that is a bear to true up. I have a 8" Yuassa super spacer with a adjustable 3-jaw chuck, I'm almost certain it has 4 adjusting screws, I'll have to look. Have a 6-jaw Bison chuck that has 4 adjusting screws that are not spaced at 90 degrees apart, it's spaced like 40-50-40-50 degre...

Look for a failed pressure relief valve, dumping all of the hi pressure oil to the reservoir. Stuck shuttle valves if any. If there is any electrically operated valves, could be a bad or weak solenoid.

I'm not about to go measure that vessel while it is under pressure. I'm going to be safely behind a containment wall just in case it does blow! As far as I recall, there is no requirement of the code to measure the expanded diameter when at test pressure. There are calculations that will tell you an...

Any air compressor tank found here in USA and most parts of the World has to have the ASME tag attached certifying it passed hydro testing at the factory. All tanks are 100% tested, no batch testing allowed that I'm aware. Safety factor at test pressure is 1.25:1, of course, it depends on what secti...

Over the past 40 plus years, My dad and myself have made many arbors like this one. We would use drill rod if we had it, if not, we always had a supply of 4140/45 heat treated in the 28-36 HRC range we would use. Never had any issues doing so. Most of the time, these arbors would get used one time a...

That's a unique looking chuck for a 3-jaw. I've seen 4-jaw universal chucks with that feature and have a couple of 3-jaw chucks with the adjustment between the back plate and chuck.

Thank you sir for the clarification.

Logan would be my guess. It's a little heavy for a South Bend, the numbers don't look like SBL. One other could be Sheldon, they use a similar numbering on their stuff. Ken

I have a bottle of red Dykem that is almost 20 years old. So far it hasn't faded. I do keep it in a reasonably 70-85 degree shop year round. Ken

One tip we used to use when checking threads by M.O.W. Take a dab of grease and apply in the thread where the wires will be placed and do this at 180 degrees from each other. Now, place the wires in the thread, the grease will hold them long enough to get a measurement. Haven't yet lost a wire using...
