Here's a LOT of drilling pilot holes, then bigger holes and flipping side to side to avoid splintering as the bigger drill bit otherwise would possibly tear out wood as it drills through the bottom surface of the wood. As you can see, I have 2X4 "backstop" but it's sooooo full of holes already but flipping side to side is even better.
If you look at the picture with the 4 legs and their attachment bases, 3 are the same type of 3-lobed smaller knobs - those will eventually get a Cotter Pin for having the same placement "detent" when the launch pad gets set up. 1 of the legs has a bigger 2-lobed knob to get more leverage to be tighter and that leg will be adjustable for uneven ground (which is all ground and grass fields) and not have pre-set "detent".
2 of the Leg "Bases" have some neat "character" spots that I'm making sure I'll have visible, and again, those spots were soaked with 2 applications of Thin Wicking Cyanoacrylate to fill all gaps inside and bond everything together. The "Bases" are pretty good dense Red Oak that I've made a really nice bow from the same plank (that was all the non-character portion - "plank wood bows" cannot have "character wood" or they'll snap") - it's sooo nice and dense I sorta wondered if I should keep it for add-on bow handles, but I have too many bows around the house already, so no real loss there.
The Legs are Mahogany remnants from our prior window-sills. I'm glad I kept the wood since it's been fun using on other projects like vertical platform for digital TV antenna, it's nice and heavy which is what I want for this launch pad.
Drilling the holes to connect the Zebrawood Platform to the Bases of the Legs is a bit of a slow careful chore in aligning, marking, pilot-hole drilling, then re-drilling the Zebrawood a little bigger to accommodate the Brass Wood-Screws bigger diameter non-threaded section under the heads, etc.
Because everything is being drilled with a handheld drill and marked "close enough but not identical" each leg, it's base and where it attaches to the Zebrawood platform are all slightly different, thus each is getting labelled "A, B, C & D".
The legs still need a bit of shaping, then the legs and their attachment bases will get sanded and finished with either the Gunstock Oil or Shellac.
Hopefully all of that makes sense.
