I have not left the key in the chuck and turned on the machine after the first time 60 years ago.
Exactly! It should be a self correcting problem.

Re: Milling a helix

Interesting that your machine doesn't run if not operated regularly. What does it do, Glenn? Mine simply did nothing at all! It seems to have various issues. The most recent, nothing on the control panel would operate and the coolant pump started running as soon as power was applied. Before that, t...

Re: Milling a helix

I've found mine DOA any time it sits unused for any extended period of time. The new deal is to run it at least every couple of weeks, even if only to run it through it's start up cycle. The start up cycle is one that I created where you give a few pulls on the lube plunger, reference the axes, and ...

Setting the angle is the real challenge, as marks on machines are not accurate enough to be reliable.
Sweeping an accurately positioned sine plate or bar with a DTI in the spindle should be plenty accurate. No?

With such a nice lathe, I hope Patio is up to the task to use it well.
Pat's got a real good grip on running it.

Re: Milling machine vise/CNC vise

For some manufacturers a CNC vise has the fixed jaw closest to you and on a milling machine vise the fixed jaw is the jaw farthest away from you. Another possibility is that some manufacturers call a CNC vise a vise that has no "ears" for the hold down studs so that multiple vises can be placed on t...

Re: How to square a 1/8” plate on the mill?

Machine the first edge using the X axis. Turn the plate ninety degrees and then indicate the machined edge using the Y axis so the edge is parallel with the Y movement of the table. Then use the X axis to machine the edge parallel to that axis. Now flip the plate to the left or right and indicate th...

Re: G0678 CNC Conversion Build Log

Someone added a folded sheet metal tray with a drain to mine of similar dimensions to your extension.

The table was made with drains as is my Bridgeport table.

Certainly nowhere near as nice as yours, but it works very well at catching the coolant.

Re: Custom Size Lapping plate

I have 11" x 15" plates with 1/4" squares, and also smaller ones I have made for specific jobs that are a diamond pattern. DSC01015.jpg DSC01016.jpg You can't just make one plate though, as they need to be lapped together to get them flat. Normally, you groove both sides of one plate and only one si...

Re: G0678 CNC Conversion Build Log

That's a REALLY nice conversion that you have done! I switched to using form taps for anything 1/4" and smaller. No swarf to pack the flutes and plug up the bottom of the hole causing tap breakage. Different tap drill sizes needed, and Moly Dee tapping fluid is the way to go, but other than that, I ...
