Last time we left off with the plane body and tool holder joined together. Next it was time to make the adjuster. What would a new plane be without a little bit of solid brass? Much like on the wood lathe I started with a piece of square stock since my step-dad didn't have any round. How much does a piece of brass cost? Mom cooked the family and I dinner so I made money on the deal. After turning a cylinder I needed to knurl the end for the "grip". Odd shapes? Another thing the CNC excels at.
The adjuster and the tool both need grooves to mate together. This gets done in the lathe. Just as a side note, if you ever decide to do some turning on an allen wrench, their pretty hard; like laughed at a tool steel cutter hard. Like made a solid carbide tool wince a little. However brass cuts like butter. I love working with brass almost as much as wood. I went with #10-32 bolts for the control so that one turn of the knob moves the iron 1/32".
Next the body was set in the vise at 30* to mill for the handle locations. I chose 30* because it looked right. It felt right. A couple of holes drilled and tapped for 1/4"-20 bolts to attach the handles and we almost have a working model.
I made a second blade out of another allen wrench, and milled it down to 1/4" wide. The handles where turned on my wood lathe on a mandrel. Currently they are poplar and two different shapes so I can feel out what I like the best. When I have a design I like I plan to turn them out of laminated walnut blanks. Why not Rosewood or some other fancy exotic? Because I don't have anything exotic laying around the shop other than pen blanks. Remember the point of this exercise is to put as little money into this thing as possible. I'm sure I will have plenty of time in it, especially after I pay my step-dad back for all the time he has put in it, to not justify buying some beautiful turning blanks for the handles.
So, why no pictures of the finished product? Why no video of the plane in action? I have encountered a small problem. Mainly to do with the irons. I think that possibly the metal lathe ways are not perfectly square to the head stock, or my technique on the work sharp is not perfect. Most likely the second of the two. The issue I ran into is that the blade does not stay engaged in the wood. As the plane moves forward the cutter ramps out and rides above the surface. The back of the iron is not perfectly parallel to the sole of the plane. What to do now? Ah, but I have a plan.
Stay tuned. Next time we cover the fix for the problem (I sorely hope as I haven't had time to make it back to my step-dad's shop to try my fix), the final details of the plane, and a nice long video of this bad boy in action (again I hope, see above hope for reference).
