Re: Buying new twist drills (ugh)

Yes, but you might use them tomorrow! Almost every one of the drills in my indexes has been used at one time or another. I am guessing that if you buy a whole set, it will not cost more than buying half a set individually.

Re: welding aluminum intake manifolds with Hobart 210mvp spool gun

Done relatively little of each, but I would opt for the TIG in your situation. if you do not want the face the learning curve, then stay with the prop shop.

Re: Rotary table use

Make your own clamps. I have made several styles of short clamps for the exact purpose you describe. Remember that we have the tools to make the tools to make....

Re: Mobilmet 766, replace periodically or just top up?

How much do you add periodically? If for example, you are adding 10 gallons a year, then you are effectively replacing the oil over a number of years.

I would tend to agree that if you have not noticed a loss of performance, then there is not a big need to replace the oil.

Re: Indicating Rough Cast Iron

It is going to be an approximation no matter what you do. I like to use the best average for the outer portion of the wheel. If the hub is too off center, you can always turn it a bit to true it up. Try a few setups and go with what looks best.

Re: Heat treat oven

If the temp controller works, than the Variac is probably unnecessary unless you wanted to reduce the heat up rate significantly.

fyi, I think a Variac is a variable transformer and not a resistor.

Re: The Preacher's Buggy or some such?

Not what you were looking for, but there are stories of Ford sending out people to check his cars in wrecking yards to determine which pieces were least worn, and adjusting manufacturing accordingly.

Re: AW Haydon synchronous motor

As far as I know, those motors are practically indestructible. No capacitor is required - just 24 VAC - and not many amps at that. No polarity. Confirm you have 24 V at the terminals - if so and it does not go, look for another.

Re: Monitor replacement

Well patience prevailed. I finally got a good monitor a few weeks ago. Dynapath got a batch of good VGA ones and the borrowed monitor has gone back to its original job. I have no desire to restore the CRT version, but I may offer it to your repair outfit as inventory.

Re: Motor and VFD for LeBlond 13" roundhead Regal

The higher HP comes in handy at higher speeds; if you are in the lower ranges, most any HP will remove enough metal (or break something), but as you turn faster, the extra HP comes into play.

Re: Motor and VFD for LeBlond 13" roundhead Regal

I had a 13" with a 1 hp and now have a 13" with a factory 3 hp. Go with the higher HP, you will never regret it.
