« Part 1: Metal working for the wood lathe Part 2 of Making a few tools for the wood lathe series Part 3: Heat treating the tool blanks (for 01 tool steel) »

I am now at the stage where I am satisfied with the basic shape and can move on to the heat treating.
Because it is so labour intensive and messy for just 2 tools I am going to send these out.
Basicially the technique is to wrap the steel then slowly bring it up to a temperature where the metal becomes ductile and the grain structure can be re aligned. It is held at a specific temperature for 1-3 hours then slowly cooled and quenched in hot oil to give the metal the hardness and ductility required.
I am trying for a RH of about 6200.

Heres a shot of the tools ready for the heat bath:

Here’s a close up showing the shape of the tips: The more finishing I do now the less labour intensive it is after heat treatment.

Finally here is a close up showing the taper I ground into the steel to allow the tool to pass through the kerf as it penetrates into the depth of the wood without binding. I wanted a strong tool so I made the depth 1-1/4” and the back is 1/8”. I don’t want any chance of it bending in the cut at 300-500 rpm.

I like both tools, that scraper looks like it will really come in handy. Should do the job. So should that rounded skew. They work great. jockmike

Great job Bob. They look like they will be great to use.

What is the anticipated cost to have the heat treating done on the outside?

Did you see Phillip Edward's post on making a forge for heat treating his plane blades? Pretty cool…

Oh my. Is it wrong to get excited when I see that skew? That’s JUST the thing I’m looking for. I hope you hate it, Bob! :) Great info, by the way!

You guys are to kind.
I have made a few tools before this and have had very good service from them.
Once you get a basic set up the metals cutting and refining is pretty easy and of course the reward is a custom tool at a fraction of the usual retail prices. Bob ,with your skill set this stuff will be a piece of cake. Jockmike the scraper is an addition to a pair of larger one I used for bowls . I wanted something with a longer reach for some boxes I will be making and the centered blade allows me to use it for spindle work instead of using 2 or 3 tools. Karson, I don’t know what the cost will be as I have usuallly done my own hardening in my shop but wanted to try a pro job to see what I am missing. I’ll let you all know the cost tomorrow. Doug I will get over to that site in the AM .
Never enough tme and always more to learn. Mot, come down some Saturday with a sketch and we’ll do one or two up for you too.

wow! Yeah, I’m with Bob… just more and more inspired to make stuff to work wood, I’ll never actually get around to doing any real woodworking. I have a friend up north who I”m trying to get some tools (and kitchen knives) out of. I”ll have to point him to this link and (make the handles myself) otherwise I’m likely to get sucked in… and… maybe I’ll end up making projects for the woodworker, instead of being one!... Nah, if I’ve learned anything over the years I’ll just add more and more things to my plate. I need a bigger plate. (or a fully financed early retirement!)
