incomplete mitre plane model

[neil schlosser]

I started a mitre plane model using sketchup. I thought I posted a thread on this yesterday, but now I can't find it. I have a basic idea of how I want to build the plane, but there are a few things I'm not sure on.

What I have so far: probably all steel construction, 2" iron, 20 degree bed, simple wedge or screw cap, no adjuster

What I'm not sure of: the length, how heavy I want it to be, which toe design, whether I should rivet or weld, how the bed should be built (considering wood)

There are actually 2 models there, to accommodate my two toe ideas. They will be secured by a screw running from the top and threading into the 3/8" bar stock on the toe. I can't figure out how to get Sketchup to let me cut a slot right now, so it's not in there.

If this link doesn't work, just search for mitre plane, only a few models will come up.

I appreciate comments and suggestions on the plan so far, as I've never owned a mitre plane. I'm hoping to throw together my wood prototype next week, if all goes well.

I think the sides should be flush with the sole so that when you adjust the mouth, you don't have gaps at the sides. Sort of more like a conventional 9 1/2 block plane.

As you likely already know welding will introduce all sorts of movement to your tool and post welding you'll have to do some grinding to flatten and square everything up. I would likely only consider the TIG process for this tool.

My thought would be to lower the bedding angle if you can.

It's kind of cold here today, and I don't want to be outside too much, so I played around with it some more. I made some modifications to pull the sides down flush with the sole, and it looks pretty good that way. I have to change a few thicknesses on things if I want to use rivets, but that should be minor. But it also corrects the problems I had with how to keep the toe lined up with the plane.

I had considered going with a lower bed angle (12 or 15 degrees), but went back to the traditional 20 degrees because I thought the iron might slip with the lower angle. I may use the lower bed angle if I can be convinced that it won't be a problem. I'm still avoiding putting an adjuster in.

Are you leaving the end of the plane you push on square? It is a lot better if you make the end a half round(half of a circle). It won't hurt your hand as much if you make it round.

The front end is usually left square.

I did a search titled" a miter plane I made" at the top of this forum. This sent me to a google listing. Select the one that says "A solid silver miter plane"-or words to that effect. There is a picture of an authentic 18th.C. reproduction of a miter plane I made for a retiring vice president of Col. Williamsburg. It has the round rear,and square front end,and the wedge type you might like to see.

That is a beautiful plane George.

I'll be watching this thread as I have a hankering to build a miter plane also. Although I think I'd rather make one from wood. I decided to make a shoulder plane infil befor making the miter plane. I have a few more evenings before I will have it done.
