This was one of those days where you spend 1.5 hours setting up for 15 minutes of cutting. I was really careful, and got the drill press table level, then installed a stop block parallel to the bit, then tilted the table, got my workpiece all set up, decided to move the stop block for more repeatable work placement, was 100% ready to go… and had to move the table up, because the bit couldn’t plunge that far. π
Raise the table (which messed up all the alignment, but I could set the plunge depth properly), re-level, redo all the alignment, stop block, tilt &c, and then I was pretty much ready to cut.
What with one thing and another, I decided that doing the rake angle at the same time as the splay angle was called for. So I gritted my teeth, added some indicator arrows to the block so I could confirm I’d done it right, and ran off a test block.
With a success under my belt, I cut 5 more blanks (5″ chunks of 2×4) on the table saw, and got started drilling the holes.
Here’s what’s sitting under all that swarf.
I did all the right-hand holes first, so I didn’t have to shift the jig around.
Then I swapped the jig (you need to rotate 30ΒΊ for one hole, and -30ΒΊ for the other), and cut the other side.
With all the holes drilled, I needed to cut them lengthwise with the table saw, to turn them into clamps. Let me be the first to say that a cross-cut sled is not the right tool for this job. But, I don’t have a working fence at the moment, so I had to make do. I still have all my fingers, but I hated this part a lot.
I was pretty excited to see whether my clamps would work.
And, after scouring the shop for enough clamps to finish the job (you can never have enough clamps), suddenly I had a fairly sturdy 6-pole truss!
Setting up to cut pole clamps is still a real pain. I really need to figure out how to cut them using my CNC’d jig (or a variant thereof), or else pole seats are going to continue to be a barrier to entry for future builds.
I decided not to take a photo of the slight misalignment of the pole holes. I think it’ll still work ok once I get them installed. And if not, I’m not moving the drill press table anytime soon. π
