Re: Grub screws

On some automotive alternator applications, the pulley is pressed onto the shaft, no key or other retaining method. With the correct fit, obviously works.

Re: Grub screws

A keyway is a far better bet. If you have only light loads, might get away with your plan, but not recommended. You do not mention shaft size. For a small shafts, a through pin is acceptable, for larger shafts, definitely a keyway.

Re: Repair Shaft Seal Surface?

Possibly grind it a few thousandths undersize? Might be able to drill a hole in a shaft saver if you have an internal support for the sleeve.

Re: Adjustable versus sized reamers.

Personally, I have never had good success with the six bladed adjustable reamers.

Re: Is the live steam hobby in decline?

A comment reflecting back to the original posting. As a member of the Cumbers and Toltec RR, we were always concerned about our membership and its gentile decline. What we found after a little research, was that almost every activity, be it golf or RR or something else, was suffering the same declin...

Re: Albrecht chucks -Tomico ID mic parts

Any clue what the chuck taper is for the Quick Switch 200 one? I have a loose Quick Switch 300 shank with Jacobs taper. Assume standard Jacobs?

Re: Collet Chuck

Yes, some collet chucks are mounted in place of the chuck with no draw tube. I have an Allison one built that way.

What you need to find is some literature or picture to see what your complete unit looks like - and figure out if an adapter of some sort is needed to mount it to the spindle.

Re: Castor wheels for the mill

Shipping container floors are solid; think fork lifts, pallet jacks, and very heavy items. Not going to punch through.

Air pallets are a good tool, I have used them to move 50,000# items. Watch out for floor drains!!

Re: Castor wheels for the mill

Ditto the idea of putting a locking pin in swivel castors so you can make them non swivel; did that on an engine hoist with good results. On my big drill press and mill on castors, I provided for jack screws near each castor, when screwed down, they prevent the equipment from shifting and can also b...

Re: How are "proper" bevel gears cut?

Somewhere, and I am unable to find it at the moment, or remember the name, there are plans for a combined feed and indexing device that allows true bevel gears to be cut on a common shaper. I had thoughts of making the device once. Obviously a very slow process as only one tooth is cut at a time, bu...

Re: Drilling small holes

Kieffer makes his own taps and dies, if I remember the article correctly. Special gearing to get the necessary TPIs. Only limit is patience.
