It basically turns your lathe into a cylindrical grinder. Good for making arbours and such.... Albiet a light duty cylindrical grinder....
It a achieves a super fine and precise finish that turning alone can not do.
D1-x mounts are great. I've helped a couple of members with ill fitting chucks, as sometimes offshore ones don't fit the standard taper very well. One machine had the taper machined and ground at the wrong angle! I have no idea... but we fixed him up, as there was just enough meat to correct it.
D1-x has to be the fiddlest fit on the planet! it pays to buy a expensive but accurate backplate for your chuck when mounting a new one. many headaches avoided that way.
So in a way, it's like a surface grinder for round work? With some limitations, one could perhaps make a ground rod using such an attachment!
I see now why others are not afraid to use it on their lathe. It isn't a convenient bench grinder at all. It's a real attachment!
Although my aversion has disappeared, I think I'd still cover my ways......
This is my second learning in one day! (The other being a reverse tumbler.) Who says new tricks cannot be taught to old dogs!
Thanks guys!
Sort of but not really - surface grinders are designed for such precision and lathe is not - it would be more similar to a milling table used for a grinder to make flat-ish surface or maybe using tool cutter and grinder for such work.
Also your lathe has to be in great shape - any excessive wear on the bed will make grinding of longer shafts to good precision a pain.
So tool post grinder for a lathe is a light duty a bit less precise alternative to cylindrical grinder. Given that in time of industrial revolution new cylindrical grinders were very, very, very expensive and took a lot of room a TPG was a great alternative. I guess I can compare it to a milling attachment - it will not turn you lathe into a mill but was (and for some is) a great alternative to a mill. Main difference is that milling is rather common operation for most shops while cylindrical grinding is rather specialty - common only in some shops. So TPG with its low price and tiny foot print at a cost of accuracy and "heavy duty" was and still is a great accessory.
Wow.for that you need one of these....a Jones Shipman 520 that came out of the Mercer indicator plant in England. Probably the smallest cylindrical grinder there is. The work head takes 8mm ww collets and I've got both the ID and OD grinding heads (OD head is sitting there askew, its not mounted). There a guy in Australian that has one, only other one I've ever heard of

Well Mcgyver, I really enjoyed your Habegger videos. I think if you ever did a walkthrough (make than a running-through) on the 520, that would certainly be of interest.
Just curious, did you acquire it via a machine shop connection vs. an auction or home based individual with discriminating taste?
Ha ha I totally understand that! However my finances and space limitations will keep that in check somewhat.one minute I didn't know such a thing existed, the next, I just had to have it!
