Regarding the two slices of plywood used to construct this log cutting jig. The clamp will rest on the first slices and the second is only to keep the clamp away from the fence, so it doesn't catch. More exactly, the second slice of plywood offers the smooth surface wanted to move the log along the fence.
The bar portion of the clamp will lay on the edge of the plywood and will be secured to it at both ends. Since the clamping parts of the clamp stick out from the bar, a cut will have to be cut out of both slices of plywood. The non-moving edge, sufficient to permit the bar to sit flat on the plywood and so that the shim slice of plywood can mount flush to the slices supporting the clamp.
Similarly, a lengthy notch must be cut for the moving part of the clamp, so that it can move up and down the distance of the bar. Leave at least an inch and a half (1-12") at the end, for the end of the bar to rest on.
To construct this jig, or sled, you want:
1) A bar clamp lengthy sufficient to clamp both ends of the logs you are going to mill into boards (this doesn't ruin the bar clamp and it can be eliminated and used for other things).
Keep in attention, equipped with a three base clamp, this jig can be closed down to hold a log only a few inches lengthy. As such, you can usage a four base bar clamp, if you don't mind the excess.
If wanted, the sled could be adapted to usage weightier duty half or three quarter inch pipe clamps. From the time when your pipe clamp jaws don’t reach out as distant as the bar clamp jaws, it would be easier to cut some logs on the left. However that would add weight and be more difficult to handle.
2) Two slices of 3/4" plywood a couple inches longer than the clamp you choose.
The slice of 3/4" plywood the clamp bases on is two edges wide. The second slice, which rides against the fence, is two and three quarters (2-3/4") wide and the same distance as the other, give or take an inch or so.
3) Two 1-1/2" (1-1/2") screws to mount the clamp to the two inch (2") slices of plywood.
4) Depending on how you want to join the two slices of plywood together, you'll want about four 1-1/4" screws or nails. I also glued mine, but, with screws, that shouldn't be necessary.
Once you've assembled your log‐cutting jig, you just want to:
1) Mount your fence to the table.
2) Place your log on the table and roll it to a place for your initial cut.
3) Clamp the‐log, tightly.
4) Fit on the band saw and dirt assortment, then start cutting, while holding the clamp alongside the fence and down to the table.
5) After the first cut, loosen the clamp, turn the log so the flat side is down, re-secure the log, then re-position the fence and create your next cut.
6) With two square edges, ninety degrees to each other, you can finish‐cutting the log into boards fair using the fence or other re‐saw guide.
