Ok, I have made the same mistake three times now. Need advise.

I have been making veneered tops with a routed decorative edge. To achieve this, I have been glueing solid wood to the substrate around the perimeter prior to veneering. After the glue up the solid wood needs to be flush trimmed.

I have been using a straight cutter with a top bearing, mounted in a router table. I have a fence, mounted high enough to let the solid wood slip under.

My problem is, getting a smooth cut, sometimes I wobble the substrate and end up with an under cut (aka divot). I have thought about placing the router outside the fence and pushing the wood through from the opposite side, but this sounds precarious. Especially since the bit now will sit away from the fence.

The other problem with this method, is I need to glue opposite sides, flush trim, then glue up the other sides, then flush trim. It would be nice to do all the trimming at once.

Anyone have a better way to do this?

TIA, Carl

When I apply edgebanding I make it about 1/32 or less thicker than the substrate and have it proud of both faces. I'll edgeband all the way around before flushing and just hit it with a beltsander to flush things up. If you have 1/64th or less to get rid of it comes off really fast. Steve

Sorry to be so late responding, but haven't been around for a while.

After struggling mightily with edge banding, I found a suggestion from another woodworker to work very well. I made an auxilliary base for the router out of 3/4" plywood (for stiffness), about 12" long and as wide as the router base. Drill and countersink holes to mount the router at one end of this base and a knob at the other end. Drill a hole about 1" diameter through the plywood under the router collet. Starting at this hole and continuing to the closest end of the plywood, remove about 3/16" of the bottom of the plywood. This creates a rabbet under about 2/3 of the router.

Mount a 3/4" or so mortising bit in the router and mount the router onto this plywood jig. Use a business card to set the bit depth just slightly higher than the bottom of the plywood jig.

Machine edge banding slightly wider than the panel and glue in place. With firm continous downward pressure on the jig handle (to keep the router and jig from tipping over) slide the mortising bit over the edge banding, trimming it just thicker than the panel. The fastest way to bring the edging flush with the panel surface, in my experience, is a card scraper.

Don,

Thanks for your reply. Your timing is perfect, and idea is great.

I read your reply last night (12/24), and today had some trimming to do. 1/2" banding. So I simplified your idea. One board with 2 holes screwed to the bottom of the router. And a good bottom cleaning bit. Worked PERFECT. Best I have done yet. Fast to set up, and best of all, the work (heavy tabletop) can be clamped.

I uploaded two pics:

Happy Holidays (I really mean Merry Christmas), Carl

Carl,

Your jig looks great.

Don, thanks for posting your idea.

I have a router jig somewhat similar except the router sticks out horizontally with a flush trim bit, this jig uses a small laminate trimmer as the weight of a full router would cause a problem since it hangs out over the edge of the board you're trimming.

Carl, You can upload pictures to your posts now in case you didn't know.

Sincerely
Darryl Keil

Thanks Darryl,

I will use the upload/attach next time.

Funny thing about my router/jig. I was using my freshly tuned hand plane to get the wood down. Nothing feels better than hand planing. The progress was looking perfect. However, I am afraid to use it as a final edge, fearing a divot, so I finish it with the jig.

So what do you think happens? The router tears out the loosey goosey mahagony. I found that back cutting prevented it AFTER I messed up a show edge. Maybe I will remember all this NEXT time I do this

Happy Holiday's y'all, Carl
