Lathe Hollowing Tool w/ Pistachio Handle

This is a little hollowing tool I made out of necessity. It is cold rolled steel with a piece of carbide in the end and the handle is made from a piece of scrap pistachio. It had some cracks in it that did not clean up so I filled them with epoxy and sawdust. It has a brass ferrule made from a plumbing nut in the recycle bucket.

I tried it out tonight on a piece of dry Jarrah and it chattered a bit, but it did not even try to turn in my hand. With the tip back from the line of the straight part of the bar, it is neutral to twisting.
I’ll try it on a few other pieces before doing any modifications. Being that it is only 5/16 rod and I milled the bottom flat, that did not leave a lot of mass . So if it still chatters, I will weld another piece of 5/16 along the top for stiffness and taper the end for clearance inside a piece..

Cheers,............and good night!!!!!!!............Jim

Very nicely done—it’s great to be able to make your own tools, especially a speciality tool that you design for your own personal needs!

Sweet tool Jim! You always extremely clever with you innovations. Tell us how well it serves it purpose. I’ll have to buy one from your future runs.

-- Thanks for all the lessons!

Jim, you have a way of coming up with items that I’ve never heard of :) this is another I’ve never heard of nor know what it is or used for, but it looks nice. :)

Edit in: I’m thinking this is something that is used on a lathe? If so then that’d explain it as I don’t have one.

Nice one Jim, the trick with these is in the sharpening around 50 to 60* & rolling of the underside bottom. not sure what your shaft thickness is & length is will contribute to chatter when your deeper in your cut if not stiff enough, most of mine run thru a collet where you can adjust the length extended so as to have just enough for the depth your working on,
Guess this is a lead in to some hollowing projects coming up? :)
keep us posted Mate
Cheers

Well done Jim, it looks professionally made. It is almost a twin to my small hollower. I bought mine with two other complimentary tools. They are perfectly sized for smaller work.

It certainly DOES look professionally made… because it WAS! :-) Great job, and great satisfaction making your own tools to suit your needs.

Thanks for all the nice comments. I never thought of what I wrote for a title. It has a pistachio handle and not for hollowing out pistachios! I changed it to be more exact.

Hi Paul, I have box full of little pieces of carbide I saved when I was a tool maker. This was a 1/8” square piece that broke off something years ago. I drilled a hole and brazed it in and it can be sharpened with a Green wheel. You don’t always need diamond to sharpen carbide.

Hi Pete, thanks for the guidance for that end angle. I have it at 45 degrees now. I can easily change it. I’ll post new pictures of it if I add the rail on top for stiffness!!

Hi Joe, Randy and Picklehead. This tool is for getting around the corner inside of small pieces being hollowed out on the lathe. Straight tools just won’t reach around the corner and when I made that flying saucer, I had to use a lot or Rube Goldberg tricks to get all the wood out of there. Now I’ll do it the right way!

Cheers, Jim

green wheel, you don’t always need diamond to cut carbide

Hi Pete, thanks for guidance on that angle. I take it to mean the included angle of the tip. I have it about 45 degrees now and I can easily change that. I wish it was adjustable but I think if I weld a rod over the top, it will be plenty stiff. I’ll have to repost it in this project so you can see how it looks and how it works.

Great looking DIY tool. I like the pistachio handle on this tool. You certainly have a lot of ingenuity about you and I appreciate you posting your jigs and tools for to see. Take care and have a great weekend.

Nice looking hollower Jim. What did you use to do the bend? You did a good job on that. All my hand made lathe tools are straight and most have 1/2’’ shafts or larger, then tapered to prevent chatter. They work well to about 6’’ deep depending on wood and moisture content. I use cold steel and 0-1 hardened for most cause of good deals. Let me know how that 5/16’’ works for the hollower. Nice choice of wood too.

Thanks Mike and Dave for the nice comments!!.

Dave, I used an acetylene torch to heat the rod to bend it. You can bend the O-1 with it and it won’t harden if you don’t quench it. I have a 5/8 shaft bent tool but it is too big for small jobs and I usually hit the back side when extracting it so I needed a little one. I don’t think this will go more than 4” deep if that but I need to get rid of that chatter.

Really a fine tool.
I love the approach to the tools: ‘if I need it, I’ll make it’, so much you Jim.
