I have a 30" long, 1/2" thick piece of plywood. I want to attach a 30" x 1/8" x 1/2" pine strip to one of the long edges. I only have 3/4" pine to cut the strips out of and it's got a bit of a curve, so my plan is to glue it to the edge in its natural curve then trim it flush to the plywood with the router:
The only router I own is a trim router. I could freehand this but with only 1/2" to rest on it's difficult to keep it from wobbling, and also the cuts will have to be cautiously slow.
I have a very no-frills, basic table I made for it. I am more than willing to add features to it since this is a problem I'd like to find a long term solution to (there is a fence too, not shown, that's just some extruded aluminum angles with a wood face, but I actually prefer just clamping wood to the table for fences because I don't have a good fence adjustment solution with a wide position range yet):
I'd be running the board, with trim attached, past the bit like this:
But I'm not sure how to stabilize it (trim not shown in next pic):
How can I do this? The problems I've had while testing:
- Freehand, difficult to keep stable as mentioned above.
- I tried putting the fence in but with the trim sticking out past both the plywood faces, I couldn't figure out how to make that work.
- I also tried just carefully holding it vertically on the table. That was about the same as free hand, a little worse because it's easier to hold the router straight than it is to hold the plywood straight. Holding too high tended to pivot away from the bit, too low into the bit. Plus this was about as slow as doing it freehand.
My goal is to have a way to do this quickly and cleanly, and as perfectly flush as the flush trim bit normally gets it. I want to put the piece on the table, zip it past, and be done. I also want to be able to do this in the future so I don't mind investing time into jig building / table upgrades.
