my parting tool holder
I was given several (9) of these when a friend retired from his tool making job sometime ago.

I took a photo of the tool holder so that I could make one later ....err, make that yesterday, and this is what I ended up with.

the photo of the one I copied shows serrations across the plate which are obviously to ensure the blade doesnt move once clamped.
Not having an easy way of putting in serrations I resorted to using 10mm grub screws that can be tightened after the plate is firmly done up.
The flat bar is pinned with hardened dowels and welded for good luck... bitofputtyherewilldisguisethecrapyweld...lol still in the learning stages of welding

I threw one of those parting tool holders in the scrap bin not long ago, would have given it to you if i knew you needed one. Worst parting off tool i have ever used. The holder you made looks good.

Nice one!
I consider them the best parting tools I've ever used..... I even made a miniature replica of mine to fit the little lathe....
What do you dislike about them snapatap?Cheers, Joe

Good work and that welding looks fine to me.
One thing I find when parting is I often seem to find I'm parting close to the chuck and luckily my parting tools have very little on the side between the parting tool and the chuck. Maybe using CS hex screws for the Mark II version ?

Although the pictures show tipped blades, the inclined holder also works well with HSS parting blades with a tapered cross section.
As the blade is narrower at the bottom, tilting it forward means it is also narrower behind the cutting edge.
So, there's no need to grind the desirable side clearance, as it's already there.
These are what I was taught to use at a TAFE evening course.

Hi Joe,
Thanks for that note. I did wonder if that was the reason why when I thought about it later. Anyway it still looks goodBest Regards:
