    Hi Peter, Thanks for the advice. I'm going to...

    Hi Peter,

    Thanks for the advice. I'm going to grind with the OD of the wheel, not with the face.

    The chuck has a small bevel (maybe 0.3mm wide) where it fits over the step in the backplate. ...

    I would need a 300mm (12") diamond wheel to grind that, something that I don't have. The tap holder is a good idea, I did not know that they even existed.
  3. As I wrote, I am not set up for inside grinding,...

    As I wrote, I am not set up for inside grinding, and don't have diamond tooling. I am confident that getting a precision polished surface and angle on a small bit of carbide is not easy.

    Hi Buck,



    Exactly. I have no qualifications or training as a machinist, and don't have much face-to-face contact with people who do. That's why I ask so many questions here. It really helps...

    Both sides of the wheel are dressed at an angle (about 1 degree) exactly for this reason. The wheel gets wider as you move away from the rotation axis towards the periphery.

    There are probably...

    Best orientation for grinding a faceplate?

    I want to true the chuck backing plate of my cylindrical grinder. This mounts in the workhead and holds a 130mm (5") grip-true chuck. My question, should I grind this with the workhead in the...

    Hi Buck,



    I didn't know that one could buy off-the-shelf TC bushings. Good to know.

    I like your idea about cutting off the end of a solid carbide tool that has a center mark already. I'll...

    What I need is shown on the second page of this catalog (first item). But the prices are not reasonable, so I am hoping that there is a less expensive source. As you can see from the cross-section,...

    Where can I purchase or order a reasonably-priced MT2 hollow-point (female) carbide dead center (60 degree)?

    I am sure that Franz would provide a quill to match your machine head's bore, ground and/or lapped to size if needed.

    Peter, I'm not an expert. But the machine looks like it's almost new and not used much. So assuming that the geometry is in good shape, I think the price is perfectly fair for a machine with an...

    Yes, at this point it makes sense to get the machine back together and running. You can work on the long-reach head later.

    By the way, I think the vertical spindle itself is sealed well enough...

    Here's a photo of the diamond dressers I have collected for my cylindrical grinder. If anyone would like to comment on which would be best suited for particular tasks, I would be interested to hear....

    I remember having to assemble that part of couple of times before getting it right, and that there was a hex-sided piece operating a cam. Is it possible that this part is the wrong way around?

    Chris, it is easy but the support plus vertical table is probably around 150kg (and might be somewhat more, I am not sure). So you will need a decent lifting system.

    That's problematic because the taper on the rear has already intruded into the wall of the MT2 socket, so there is not enough meat. Also, the steel is hardened which means that turning it with CBN...

    Hi Buck,



    Fair enough, I owe a lot more than that to you and the others here. But I didn't take any photos of that grinding.

    However I do have a few photos from a couple of weeks back. ...
  22. Why is the back of the grinder tailstock quill tapered like this?

    My cylindrical grinder's tailstock came with this taper on the back of the quill. I thought it was deliberate, but am starting to think it was done to cover up grinding dings/crash marks. Is that...

    It's looking good. Since you have all of the painting supplies at hand, and are getting nice results with a brush, at this point it might make sense to degrease the base and paint that as well.

    Correct. Catalysts and catalysis have nothing to do with capacitors or electrolytic capacitors. So in post #12 you should have written "electrolytic" not "catalytic".

    I know these as "electrolytic capacitors" rather than as "catalytic capacitors". Is that really what you mean to say?
