Spline Grooves In conference tables3/18
Good morning! I am looking for some information regarding spline grooves to help align and strengthen the two edges where sections of conference table tops meet. Currently, I use biscuits, and its done by hand. I would like to move to a spline material. My question is what kind of material/thickness/supplier should i use? Also, what would be the best tooling for the groove? I would prefer to avoid wood, due to taking up capacity in the shop. If i could buy some plastic strips or Masonite, that would be preferable. The setting is a high volume shop. Thank you!
I have used masonite in a 1/8" routed groove successfully to align panels within a few thousandths. Dominos also work well. Both are far better than biscuits.
I second the dominos. There is nothing quicker for location and alignment. I have never tested them for strength but I bet they are way better than biscuits which suck!
Great, I will try that. Thank you guys! Do you have a supplier you use regularly?
In using solid wood for a table top, the wider the boards are the more likely they may react to expansion and contraction. That happens across the grain, so your "bridges" should not be screwed tightly to each board. You could screw to each board if you use a slotted hole, which would allow for any movement.
