Parting Tool Holder

I finally got round to making my first tool holder for my lathe. I bought the parting tool from Arc with the block that fits the standard holder and it worked ok but the extra overhang always bugged me so decided to make this based loosely on the type you can buy for Dickson style toolposts. I decided to make it to a fixed height since it is dedicated to a single cutting tool but if it turns out that some fine adjustment is necessary I can always put a screw through the top of the "hook". The main chunk is cold rolled steel, the hook and the clamping bar are silver steel - the clamp bar was hardened with torch and oil quench.

Nice work, but I think you will miss the height adjustment. may be you could have a shim below if needed.

I like the touch with the producers name and year. Is it punched or engraved?

The less overhang the better, that is why I avoid QCTP's.

William, I've worked with many different tool holding systems & all their have pros & cons, never really found QCTP's a problem. keep up the good work.

Normally, I advocate absolute rigidity, but in the case of parting tools, a little flexibility could be an advantage, in that it will allow the tool to "give" when the going gets tough, and avoid a dig in.

The holder that I was given, many years ago, is slotted, and when being used in the rear toolpost, it can be seen to yielding slightly. At the risk of asking for problems, dig ins are almost unknown.

Brief use so far suggests the height is right but as you say I can always shim it if it needs to go up a bit. Can't shim it downwards though! If it turns out to be too high I can take a bit off the hook. The letters are very inexpertly done with a cheap set of punches.
