When I put a picture frame together with 4 mitered corners I use a clamping fixture with 4 v-blocks and a draw bolt in the center. But when I put hardwood trim on the outer edges of a top it is always a challenge getting them all to stay together to clamp up properly. I cannot use the frame fixture because there is no space in the center. I used to air nail the pieces on but then that left holes to fill.
So I tried this and it worked pretty good so I thought I’d share it with everyone.

I make sure the center part is square and put it face down on the bench and then cut all the trim pieces to fit precisely without gaps.

Then I glue the perimeter of the center piece and the mitered surfaces of the edge trim. I place the pieces against center section and put one clamp to keep them from moving while I contain all the trim with a double bungee cord.

I let it sit for a bit and then flip it over so I can see how flush the trim is to the surface and add clamps in all the critical areas until the glue is dry.

After is is dry, I just sand the top to make sure the center and trims are flush before finish routing the edges.

There are probably a lot of ways to do this but I found this saved me a lot of grief over the old way I used to do it. The bulk bungee cord I bought at a flea market for another project and it really worked out good because it maintained pressure on all 4 corners. I usually dry fit it with the bungee cord on it to make sure the miters are all correct. They are a lot easier to recut without glue on them!!

Hi Jim, I have wondered if this type of method could work.

Thanks for sharing this hand hint Jim

Jim, Veritas makes a “4 way speed clamp” that does what you are doing. Much easier. I use them for most all of my miter cut clamping

I thought about doing the same but, I’m so slow. I think I’m the vice president of the “Procrastinators Club of America”. Not too sure cause I haven’t opened the letter yet.

Hi Sam. I figured there are lot of other methods. Do you use clamps after taping the trims together?

Good thinking Jim. Ratchet straps work well also.

Hey Jim, that is a great method to use for trim. I will have to add that to my arsenal.
One thing I thought I should mention is to be careful glueing your end grain with you edge piece. When you have two different grains going in two different directions and you lock them in place with glue, you will experience splitting and your miters will come apart. However with plywood it will not matter. Hard to tell on your pic if you are using ply. One thing I have done is glue the miter and not the edge of the end grain plus add a spline in the miters to hold them together, plus it adds a nice touch to each joint.

Hi Drew. I have made a ton of tables this way- gluing the corers with the side solid pieces and have not had one split or come apart in any way. I usually use plywood for the center, but in this case I scrapped the plywood and used solid wood. This was cabinet grade plywood that I had left over from a job I finished and the customer bought the wood at the Home Despot. It had such a thin outer ply that I could have sanded through it before I knew it. Time will tell on these if the expansion of the sold does break the corner. I’ll keep an eye on them during seasonal changes. I have not done any spline joints yet but have been thinking about….............Jim
