My son inherited my grandfather's old wood lathe. It came with a steady rest that featured 3 rubber rollers. . .
If the original were rubber, I wonder how desirable hard rollers would be?

Re: Sticking acetal tires on steel bearings

You definitely need sealed bearings. Open bearings are only for inside sealed chambers. . . You'd think so, but every bench grinder I've ever had used shielded bearings (no actual seal contact with the inner race) and they last a very long time. Same with my router and table saw. None of these were...

Re: Boring Head Questions

I think GlennW is probably right. If after a lot of work on the head you screw up a hole it just makes sense to make a few bars that size since the bars were going to be home-made anyway. If you have room, you could bore both holes to a standard size.

Careful there! The only thing worse than chinese tools/tooling is that made in India. It is possible to get good quality from Taiwan, though.

Re: Source for high-strength metric bolts

Ordinary socket head cap screws from reputable manufacturers, metric or imperial, are high-strength parts.

Re: Is this any good for way oil?

Actually, way oil viscosity varies with the application. Flat/box ways often use a lower viscosity while Vee ways use higher. The ever-popular Mobile Vactra No. 2 is ISO-68, or roughly 30W. Although it isn't necessarily the best for Vee ways, it is readily available, not terribly expensive and works...

Re: Machinist's Level help

Go ahead and use it. Accuracy means nothing, sensitivity is what matters. Unless you consider coolant drainage, for which a carpenters level is adequate, a lathe needn't be level at all. Just flat. Therefore you can 'level' your lathe with the bubble a couple of graduations off center, so long as yo...

Re: How to increase tightness between splined pieces?

You've probably finished by now, but it might be possible to shrink the receiver. If it is steel, heat the bore to red/orange quickly with an OA torch from the inside, then let cool. Spun bearing seats in auto hubs have been tightened up this way. Get it hot enough the first time because subsequent ...

Re: Has anyone built a guide for a center drill.

You've got 4 to do. If they're all the same, just set up the steady and don't change anything between parts. If they're not the same, well.... you've only got 4 to do. You'd have 'em done by now! In my opinion, nothing's broken/nothing needs fixing.

Re: Annular cutters

Quality annular cutters, properly held, will make a very accurate hole. No need to start with 1-7/8 and bore unless you need a tolerance measured in single-digit thousandths. Hand-held drill, no. Gooddrill press or mill, yes.

Re: Millrite Clamping kit T nut help.

I bought a Te-Co set from Enco many years ago that works perfectly with my Millrite without modification. The nuts are: 1" base, .62" step width and the overall height is .625". The bolts are 1/2". You don't need or want T-nuts to fit very close in the slots, that just makes them hard to move/positi...
