Started this a few days ago, but haven’t had much opportunity to be in the shop to get it finished. I ran into an issue of my own making. I saw it coming, but thought “Ah maybe it won’t happen.”
I used a piece of 3/4” AC for the bottom of the torsion box. It was a little warped but thought it would get pulled back when it was glued and screwed to the MDF that already had the center cells glued to it. Figured the 3/4” MDF with the grid was pretty rigid and the plywood would just conform. Well nope. Wasn’t happening. Put a bow in the top of about 1/8” or more at the center. I should have used another piece of MDF or a 1/2” sheet of finish grade ply, but I had the 3/4” AC and wanted to use it so it wasn’t hanging around the shop.
Now I was at a loss to try and figure out how to make this not a total loss. The 3/4” AC was glued and screwed and wasn’t coming off. It was either fix it or cut the whole thing up. Cutting slots across the plywood that went 2/3rds thru the board relieved most of the stress that caused the bow, but not 100%. The remainder was done by rabbeting the maple skirts to fit over the edge of the top. Had to router the edge of the MDF to accept the rabbet.
Well I lived and learned from my hasty laziness. Here’s some pics of the unfortunate event that just added more work to something that shouldn’t have been that much work :)
Finally got a chance to use my miter saw station for some fabrication.
I realized I forgot to buy some pipe so I could make longer clamps for glueing the edges to the darn thing. Had to jury rig it, but it actually worked pretty well.
Made a nice little purchase from CL the other night. Sold my 12” Ridgid miter saw to a soon to retire NYC cop who makes wood toys and stuff to sell at fairs and picked up this Shop Fox mortiser from a different cop for $170 including the set of Grizzly bits that have yet to be used. Think it was a good score. I’ll be using it to build my workbench, when ever that may be :)
Oh one more thing. Picked up some flat neodymium magnets to make a jig for setting the knives on the jointer. Bought extra and used one on the fence to hold up the lever. Works great! :)
