I broke one of the lamms* on my loom and need to make a replacement. It is a piece of wood, 1″x42″ and just under 1/2″ thick. I have some 1/4″ plywood that is long enough, and two pieces glued together would be the perfect thickness.
1. How do you cut even strips off a sheet of plywood, when there are no straight edges to press against the fence?
2. My tablesaw has a clear plastic blade guard. If I cut a narrow piece of wood, the fence can’t get close enough to the blade unless I lift the blade guard, which I don’t want to do. There is room to use both fence and blade guard if I inserting a spacer between the workpiece and the fence–but again, how do I get an even strip of wood to use as the spacer?

*A lamm is a bar between a shaft and the treadles, used to center the pull from the treadles. The picture shows a lamm tilted from the pull of the last treadle. You can’t see it, but the lamm is suspended at its midpoint. So, even though the treadle is off to the side, its pull transferred to the center.

Fasten the plywood to a wider straight piece of wood with screws, a few nails or even some good double back tape. You could even use a couple of spots of glue with a piece of paper between the main board and plywood. The paper joint breaks apart pretty easily and cleans up with a scraper and or sandpaper. You could also use a router and a straight piece of wood to true your plywood. There's a lot of ways to do this.
*the easiest solution is to straighten an edge (jointer, handplane, sander) and then rip it. now you know first hand why people hate the cheap american blade guards. since you don't want to remove it, set your fence so that the offcut to the left of the blade will be 1".
*What other kinds of blade guards are there?

*Can't imagine how it posted twice. Delta and Biesemeyer make a European style guard and there's the Brett guard sold by HTC. I've also seen people mount a piece of wood on the splitter which covers the top of the blade.
