Re: titan machinery milling machine defect

I agree with John.

There's no way a precision surface on which the machine depends for accuracy should look like that.

Even if it actually worked to get it trammed, the rough surface would wear out shortly and it would probably be worse than it originally was.

Re: Wanted 5C Collets

A 5C collet can pull down quite a way from the stated measurement . Yes, it can pull down, but when you do that, you may find that the work isn't being held securely because the collet is gripping only at the face. 5C collets, unlike ER collets, are not very tolerant of under-/over-sized workpieces...

Re: Wanted 5C Collets

You might want to make up split sleeves with an OD of a collet you have and an ID of the needed sizes. I made some when the only collet I had for my mill was 5/8" and all my end mills were 1/4 and 1/2. Put a shoulder on it so that it won't fall into the collet and knurl the end to make it easy to pu...

Someone in this thread:

says keep adding it in until it won't dissolve any more.

Re: 3-Phase plug / socket

OK, thanks.

I need to test the motor and a friend is using L15-20 for his 3-phase outlet, so I'll be good with that.

3-Phase plug / socket

I have a 3/4 hp 3-phase motor, and a static 3-phase converter. I will eventually be building a rotary phase converter out of an old 1-1/2 hp 3-phase motor. What is the "standard" 3-phase plug for this sort of application? I understand that I could use anything I wanted and it wouldn't matter as long...

Re: Small Diameter Slitting Saw

I drill six 1/8 holes into a 0.75" drill rod blank at a calculated hole circle to give me 12 degrees rake at 0.5" dia. Then I turn down the cutter to final size exposing the teeth; then mill a straight relief behind the teeth. The blank can be easily made hollow ground, it looks like a washer and m...

Re: Small Diameter Slitting Saw

There are little saws available for Dremel. They are very thin. They attach to an arbor (you could easily make your own). The ones I have are about 3/4" diameter. Maybe there are some smaller. Probably not good for cutting steel, but might work on aluminum. Horror Freight has them as small as 3/4" h...

Re: machining should square

I took Chief's crazy suggestion, pulled the guards off, chucked up one end of the shaft (too lazy to get out the collets and I was machining the other end anyway), and put the other end in the live center. 20190411_204728.jpg I gave it a light cut and that made an improvement. Then I swapped out the...

Re: machining should square

Maybe make another inner washer that has a reasonably long bore and is a snug slip fit. That way it is shaft located and square, and the shoulder isn't responsible for squaring. If, like like with my 7" grinder washers, you are using a larger hole wheel anway, you should have plenty of bore length ...

Re: machining should square

I find it hard to believe that the shoulder on a turned shaft wouldn't be square - seems like it would be hard to make a shaft with an out-of-square shoulder. I'd be looking hard for something else! I pressed the washer against the shoulder and turned the other end of the shaft and I could feel and...
