Topic tags/keywords: question taper angle

The project I am working on requires 4 circle-ish shapes that are about 6 inches in diameter and the thickness tapers from 3/4” to 1/32” or so. I am using poplar because this part will not be seen, but it will act as a spacer between two pieces of oak. If that was not clear, perhaps this would help: If I had a thickness planner I would shim up a board to give me the angle/taper I needed and then use that as the reference surface for my pieces.

As I do not have a thicknesser, I tried to use handplanes but removing that much material is taking a whole lot of work and clamping it is tough as I am trying to taper the face of the board. When I shim it up, to get the line I want to be flat, the support below the piece is not great, the thin edge is hard to register against a dog or stop without the stop getting in the way of the plane. Handplanes seem to be a no go as the piece is just too thin on one end to clamp safely and still give me access to the face of the board.

My only other thought is to rough cut off the waste (or most of it) with a handsaw (the piece is too tall to run through my bandsaw’s 4” resaw capability) and use a rasp or file to true the face.

Before I embark, any other ideas?

how about a router instead of a thicknesser? you can create a frame that will sit above your work piece. the work piece will lay underneath the frame and will be shimmed to give you the required taper. than using a router sled on the frame route the waste out. sort of like thicknessing end-grain cutting boards, only at a taper.

Belt sander with a coarse grit will take away most of the stuff.

If you have a router you could make Stumpy’s horizontal router stand (or something similar) and use that. Would work great i think.

Build a router sled and elevate one side of the workpiece.
