  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

While I was setting up a PM 835 yesterday, I noticed this part drop down, I think it came from the quill when I was rotating the head to the vertical position. I asked Matt, and he tells me that it is included in all Mills and he has no idea what it’s for. Anyone here have any thoughts?

Depth stop rod on the side of the head, see red arrow. Should be like a half moon semi circle with a flat.

That looks like a good guess. I never have figured out how those things work.

On my BP clone I use that rod to hold a cool mist nozzle

OK, another dumb question what is that structure molded in the back of the mill used for? It looks like a large rod should fit into it. But it is very roughly casted and it appears that they used a lot of Bondo it to try to shape what was probably a very rough cast part

For the back of the casting bridgeport mills have a brouch attachment so you can cut keyways
The little rod is supposed to hold a indicator but i have never had much luck with them it would be nice to do keyways but just using a brouch with a press is easier
