Bar corner joint of oak

Hello everyone,

I'm new here, and have been reading a lot. I have built bar tops for customers before but not of this size or environment and I am trying to decide the joining of this corner.

The bar is 18" wide made of 3 sections to form a "L". The length of the pieces are: 6' butt to a 22.5˚ miter, next piece is 3', mitered on both sides to a 7' long section forming the "L".

The material is 3/4" flat sawn solid oak, 3 1/2" wide planks, alternating grain (smile up, smile down to minimize cupping), glued and joined using biscuits for alignment. There is an apron on the back of the bar to conceal the plywood base and the nose has a beefy apron which I am going about to add a 3'4" round over. The bar will be sitting on top of plywood base with a sheet of rosin paper between the two. I plan on drilling 1/2" holes through the plywood then fastening the bar top down with screws centered through the 1/2" holes with fender washers so the top can move. That's what I am working with. The bottom of the oak will be sealed along with the top. I haven't figured that part out yet.

The bar is going in a coffee shop. Sometimes it is really hot in there, especially when I go for coffee in the morning as the equipment heats up the space quite a lot over night when they are closed and shut off the air.

I am having a hard time deciding on a joint type for the bar corners. I was thinking about doing a blind spline. Not sure if I should glue it.

What do you think? I've read everything from gluing the outside 3" of the corners and bolting the pieces together, to just countertop bolts, biscuits (yuck). I want the corner to stay together if possible due to drink spills and hopefully pull my finish over the joints and not have it crack. I suppose that would be gluing the spline.

Any suggestions would be greatly appreciated.

Thanks,

Tom

I would suggest giving some details of what you are trying to do and asking the question you want answered.

After reading all of the post I didn't really know what the question was or cared.I just got bored and tired of trying to take everything in you were saying to answer a simple question.
Welcome to the forum.

That's a little uneededly harsh dude. Guy was trying to give all the pertinent details to the project at hand so a good answer could be given that applies to his situation. No need to be so rude because you didn't care to read

To the op: personally I would try a splined miter, but I don't know how well that would hold up through the heat swings and drinks spilled. I'd imagine properly done and with a good finish the join shouldn't really tear itself apart, but I don't have much experience in that area

I made a bartop that was from QSWO and mitered at a 90 (45 x 45). I used biscuits and pocket screws and West System Epoxy to glue the joint. Finished both sides of the bar equally to keep it balanced.

Thanks for all the replies! I was just trying to be full disclosure with my post about the project so we all knew what we were working with.

The bar will be assembled in my shop and finished there too then transported to the site for an after-hours installation.

So the blind spline it is. I actually feel good about it too now that a few have suggested it to me. I am just setting up my guide to cut my miters and have a 1/4" kerf slot cutter for my router with a bearing which will set the depth at 3/8" deep. So the spline will be decent in size.

As far a finish goes, I'm not crazy about epoxy. I know a lot of people dig it, but it just looks so plastic-like. I know it is highly durable, but the look isn't for me and I never liked applying it either because it is so messy. I was considering system three's spar varnish, which is similar to epoxy. The shop owner said that is what he would like me to use. I've never used it before but it seems like a good product. 4-6 hrs curing time, thinnable. Apparently another patron which is also a woodworker turned him on to it. It has uv protection in it too. I suppose I could sway the owner to something, but I really don't want to go epoxy.

Thanks again for the replies and warm welcome! :smile:

All the best,

Tom
