I'll do them for free without a part file. I just program it off the drawing. Start and stop tangent points of the radii would be helpful, but not re...

The nut didn't back off. It has a conical angle on the underside that makes it look like it did.

What did your helper say to the HR girl?

[Toolguy]

Glad you're still with us, Boslab! You went for a hell of a ride on that one! I say - Whatever doesn't kill you, makes you meaner. Best Wishes.

The mandrel is to support the tube and give the cutting wheel something to push against. You would have clean, square ends right on length....

[Toolguy]

Maybe a tubing cutter with a 6mm mandrel inside the tube. Just big enough for a slip fit, not press fit. You could possibly turn a 3/8" bar on the...

My vote is for S7 at around 55 Rc, also. You get it as drill rod for a fairly low price. When heat treating, bring it to full hardness, then draw it back,...

Sorry- I don't have any paperwork on them. I used machine spindle oil in mine, and they have been fine for years.

I see you have a few ettco tapping heads. Might you have the user/service manual for the ettco 1B or might you know what the recommended Oil to fill...

You have to draw it to 3D print it.

Where do you put the gas in?

Edit- I know it's not done yet, just kidding. Great looking engine!

Did anyone notice that the 1st bag was already leaking before she put it in the other one?

The 300 straight 6 was one of Ford's best engines. Not great on mileage, but lots of power and would go forever.

[Toolguy]

It's not linear. The velocity component is squared, which makes it more important than the weight component. There are upper and lower limits on what...

I got a Shop Vac hangup pro and hung it on the wall. It has a looong hose. I turn it on and off with a remote from Woodcraft Supply. Then just take the...

Here she is in English. https://www.youtube.com/watch?v=eEK9tPSSZpQ

Great vid, BF! Never seen that before. That guy is truly a musician!

[Toolguy]

That one goes to about 1 inch (25mm). Paul needs one that will do 3.5 inches.

[Toolguy]

Yep - always do a first article inspection, like Jerry says. Same goes for manual machining, but if you don't do CNC right, it's just a faster way to...
