Parting Tool Holder

[rossbotics]

I been working on my small lathe doing a few things to it I been wanting to do, I made a new tool post holder for it a while back along with a boring bar holder but never made a parting blade holder, until yesterday.

I had this 1/16” X 1/2" X 4 ½” HSS blade in the drawer that I thought would be about the perfect size for this little creature, so I sit down and did a little drawing and this is what I came up with, this parting tool holder has a tongue protruding out on the right side so it can be clamped in the tool post just like a tool bit, this is also how the boring bar holder is clamped, the parting tool holder is made from O-1 steel which is hardened and ground, the holder has a .055” Dp. X ½” Wd. Slot milled and ground at just the right height so the top of the parting blade is on center of the machines axis, it has a flat plate with six 4-40 flat head screws clamping the blade tightly in its seat.

Below you will find a few photos of the machining process and the tool installed in the lathe.

As always thanks for looking and happy machining.

rossbotics,

Very nice, clean workmanship as always! That is a great addition to your new tool post. I could not tell from the pictures if the tool itself is inclined or has zero rake. By the way, I sure like the tool post with the corner removed from the tail stock end. That side sure can get it the way at times.

Thanks old_toolmaker
The blade is at a o-rake, yes the clearance on the right hand side of the tool post really does help, need all the clearance you can get on these little machines

Doug,

Nicely Crafted! I also think that creating extra room for your live center is a good idea!

Thanks for sharing,

rossbotics,

Thanks for the reply. I am now thinking of making a rear parting tool holder. I like your clamping mechanism.

[rossbotics]

That sounds cool making a rear one, I made the clamping mech. so I could work really close to the chuck.

rossbotics,

Thanks for the reply. I am now thinking of making a rear parting tool holder. I like your clamping mechanism.

For me a rear parting tool has been the way to go, the smaller the lathe the more you need one. No more dig ins and I can now part off 2 inch steel discs with power feed. As long as you have a crosslide that will accept one.

olderdan,

Another option for those who do not have a suitable cross slide for a rear parting tool would be to make a new cross slide. A few years ago I re-purposed a production cross slide for an 11" Logan lathe.

Nice modification, I happen to have done a similar thing using a Myford super 7 slide on my SB.

Not a quick job but well worth it especially if you mill in the lathe, more on my builders page.
I have done so many mods to this lathe over the years I now think I should have put them in one place.
