Here’s today’s progress on the Biesmeyer style fence for my dinky toy saw. The spring clamps are clamping the cam handle together prior to working it into shape. The socket head cap screws on the top will secure the fence to the clamp. I was going to use plain hex cap screws but I thought the socket heads would look better and either way they are going to be counter-bored below the surface.
I already tried the clamp with the MDF cam and it clamps completely solidly tight. I’ll probably go to a Maple or oak cam later on. You can see in some of the photos how the ¾”dowel is in there acting as a plunger for the cam to press. I’m likely going to need to bush the holes with at least steel bushings or they will wear oval and I want the pieces that wear out to be replaceable not the ones that aren’t.
I’m going to build a micro-adjuster next for it because I don’t believe as nicely as it slides around that it will be an ‘adjust by bumping’ type of fence. This fence is very heavy.
p.s. If you ever use carriage bolts then you need to use the thing that is lying on top of the fence by the cap screws to prevent the square on the carriage bolt from rounding out the hole.
I tried the fence out with the clamping assembly attached in one place by the cap screw and clamps in two other locations and all I can say is: ‘That dog will hunt!’ It is heavy but it glides over the table and it locks right in square again. And, the longer fence face even gives a better cut without the wobble at the beginning and end of the cut. It is so smooth sawing against it with the Melamine faces but I am still intending on installing thread inserts and using a removable face so as not to wreck the body of the fence itself. At this point I would be willing to say; ‘It worked’. I have my Biesmeyer fence now.
