The Home Machinist!

In no way am I anything close to a bearing expert, but the bigger bearing manufacturer's all have engineering specifications for most common bearings and what they can withstand for radial and axial loads. Surprisingly off the shelf standard ball bearings have some pretty high ratings for those radi...

Like anything in our shops your going to get what your willing to pay for. I do know the Te-Co clamping kits are hardened to where I wouldn't want to try milling them. Unfortunately it seems the price goes way up for anything larger or smaller than the standard BP table slot size. But as already men...

I can't say for sure with that machine, but it's more than common where two set screws are used in the same hole. The second is used to lock the first in it's position and keep it from loosening. Have you checked for that?

It's complicated and there's many that used almost an industry wide common signal standard while a very few other manufacturers use the less standard for there systems. Heidenhain for sure and I think maybe it was Acu-Rite? used a far less common signal type. But there were probably others. About al...

That steeper angle also may have been a work around to gain extra surface contact area. For some items on models and the non scalable laws of physics they work against us. So you need to sometimes cheat a bit to get it to work. And my limited information matches up with Russ's, under 8-10 degrees is...

Personally I wouldn't trust any copper scrap that is going to have steam pressure on it. And bed rails? I learned more than I wanted to just trying to drill them. It's just about worthless in a home shop. I can't afford any free material that's going to burn up more in tools than just buying the cor...

On that machine no, but hydraulics are hydraulics. If other hydraulically driven functions are working normally and at the same usual speeds then the filter, intake screen and pump should be fine. Broken line or fitting is my best guess. Figuring out which one IF you can get to it shouldn't be hard ...

Just machine a set of tee nuts to fit your table slots, then drill/tap for the size of bolts the rotary table uses. Just be careful NOT to tap right through the tee nuts. You want the bolt threads to jam against the incomplete thread so your not jacking the tee nut up against the tee slots upper lip...

It's not easy to find short bodied key less chucks. And a drill chuck that's decently accurate keyed or key less isn't that easy to find today. And there's no durable, accurate and cheap chucks that's for sure. But a key less including even the Albrecht's still can't hold every drill you might be us...

That's certainly a reasonable cost for something this obscure. But there's not a hope 27, 28, or 0.9mm are all going to work or be even close to being anything close to interchangeable as the OP seems to think. In round numbers there's a .013" difference per full turn between a 27 tpi and 28 tpi thr...

I don't own one of the Starrett's (yet) so I can't say for sure. Looking at pictures though they appear surface ground so there likely hardened. If so I guess the precision term fit's in with that surface grinding. But at least they seem not to have changed the quality or how there being made. The k...

Yes it could well be metric, not a 100% certainty of that though. As already mentioned, thread standards obviously changed over the years. Also certain industry's used common standards within that industry. There was a constant thread pitch size of 26 tpi used and called I think either a Cycle or Br...
