The Home Machinist!

I have a few I can send you. They are NOS stainless steel Albany Products about 30-40 years old. We are in the process of cleaning out my dad's shop and I grabbed some out of the drawer before we wrapped up the drawer unit. I can't pull any more out as the drawer unit is wrapped and taped. I think I...

I have an inspection sheet for a Clausing 5900, with detail of each test (printed) and the results (hand written in pen). It has the serial number written right on the inspection sheet. I think the inspection report is actually part of the owners manual. On the other hand, the inspection sheet for m...

Would you wrench your back on that?

One thing. If you silver solder, DO NOT use a steel backer. Not unless you want it to become part of the hinge. If you gas braze or TIG, it most likely won't be a problem, though. That was my first thought about that, but I suspect that you could use a steel backing plate with spacers to hold the p...

Yes, that is something that CNC can do. I looked at laser engraving for a project and the setup charge was $75, and this was going to be for a one-off piece. Do you have a local makers club in the area? Maybe you can contract with them. It might cost a lot less than an engraving shop and the money w...

I don't care about the wheel size...for a riding car, it matters not to me...

The smaller wheel size for scale is probably an advantage with the lower center of gravity.

This needs to be emphasized. The goal when tightening a bolt is to achieve a specific amount of tension in the shank, not to reach a specific torque. The torque is just a convenient but indirect (and inaccurate) indicator of tension. I remember the head bolts on a car that tightened to a specific (...

The lug nuts look like this: 21260489_dag_6112121_pri_larg.jpg The taper is only there for use with the spare tire - the flat washer rests against the wheel. I don't have a dial or beam wrench, so I used a click wrench and kept lowering the setting until the nut moved before the click. I realize tha...

The lug nuts on a Toyota Sienna are M12 x 1.5.

The manufacturer spec is 80 ft-lbs, which produces a predetermined (but unknown to me) bolt stretch.

The dealer put them on with 130 ft-lbs.

Is there any way with just that information to calculate if the bolts have been excessively stretched?

I remember years ago when the movie "Das Boot" came out.

A friend, who was an expert in German arms said that the only thing he could find that was wrong was that the grips on the captain's pistol were wrong. The PISTOL was correct, but the grips were wrong.

I bought my can of nickel-based anti seize 35 years ago and still have more than half of it left. It will probably outlive me (and I'm younger than Bill). I can see how, if you were to exceed the melting point of nickel, it would weld things together, but that temperature is above anything I work wi...

If the alternative to a 7/8" collet is to put a 3/4" shank 7/8" end mill holder in, then you probably would be better off with the collet, as the overhang will be far less.
