Rest of Nibbling Chisel also known as plane irons

Phil Smith

>Bill mintioned below that he sent the nibbling chisel out for heat treating when we have an order sufficient for treating. Well here is most of the rest of the heat treating order.

Early last year Wiley Horne inquired if we were interested in making some CPM 3V plane irons for infill planes. Well here is the result of that initial request which would up with long infill plane irons and a couple of plane irons for a LN 4 1/2 for Wiley, and short infill plane irons for Steve Elliott along with some plane irons for LN No. 4 1/2 and for a No. 5 bench plane and couple of plane irons for wooden block planes for the guys in East Tennessee. Most of the machine work was done by a machinest friend Burce Norton along with some outside work at a local machine shop for initial blanchard grinding to rough thickness before heat treating along with finish grinding on the surface grinder after heat terating.

I had posted pictures of the irons earlier before heat treating and surface grinding.

The irons have all had the initial bevel ground to about 27 degree and are ready for finish honing of the back and honing of the bevel.

We also made 4 irons out of CPM M4 tool steel which should give us a significant bump in performance over the 3V. They are currently out for finish surface grinding. I will post pictures of those at a later date. Next step is to make a couple of irons out of CPM 10V to see if we can get another bump in performance over the M4.

Below are pictures of the short infill plane plane irons back side. I will post additional pictures of the other plane irons.

East TN irons back along with

>Back of East Tennessee plane irons. Notice the pile of grit in the back ground that is the grit from grinding wheel used to establish the bevel on the plane irons. I used a 7 inch 46 grit very soft pink wheel on a 3450 rpm grinder to remove most of the steel and then finish ground the bevel with a 100 grit wheel that Bill special ordered to put on the finish bevel. Used about 1/4 off the 46 grit wheel putting the initial bevel on the irons. On a good night I can grind to the edge and go directly from the grinder to 1 micron diamond and a cast iron lapping plate. Two of the irons have the back polished with 1 micron diamond and the bevel sharpened with 1 micron diamond. I included a walnut test shaving on the LN 4 1/2 iron.

Thanks for a great project!!

>Hi Folks,

Phil Smith, Bruce Norton, and Bill Tindall are three extremely reliable, trustworthy, and detail-conscious people. Which is what you want when the finished blades need to mic to the thousandth. They're highly qualified engineers and scientists, and are used to tight specs. Actually, Bill Tindall was not involved in the blade making directly, but he has to be mentioned prominently because his own work in making the 3V chisels, and ploughing through all the details of diamond media sharpening, has been an inspiration for the rest of us. Course, he should also be mentioned for skinning out that roadkill deer on the way to the opera, too. Anyway, the blades are now on their way to Steve Elliott, who is getting his branding arn hot. Steve and Bill were the guys who worked with Paul Bos on the heat-treat schedule for 3V. Steve is also doing edge-durability testing of the various blade steels, as well as tests of plane tuning and setup. Me? I just came along for the ride.

If any of you diamond media sharpeners or motorized sharpeners (it takes that to deal with CPM3V or M4) are interested in custom blades, I encourage you to contact Phil Smith.

In a more general sense, our little project also shows that you can organize and successfully carry out a fairly complex project with your fellow WoodCentralians! Whether it be blades or something totally unrelated. There is a tremendous skills base on this forum.

Thanks again to Phil Smith and Bruce Norton for making the difficult look easy.

Wiley
