I’ve been procrastinating finishing the cab restoration on my Flight 2000. I have successfully made it structurally sound, refitted the front panel, made it square again etc. The front was held together with screws - like a lot of them. So i’ve rebuilt that corner using fiberglass resin.

I still have some work to do before i paint. One task is redrilling the leg bolt hole since they were filled in with the resin. What is recommended to do to make sure the holes are drilled and aligned properly. Def not free handing these. Are there jigs that people use? Strap a leg to the cab and use that? Hoping to not f up my edge and have to redo lol

Make a drilling jig that fits around the corner with holes drilled on a flat in the right spacing. Here's a cross section.

Keep in mind that resin is brittle and will chip.

There is an existing 3D print on Thingiverse https://www.thingiverse.com/thing:3348794

or

Place the leg plates on the inside of the cab and use the holes as guides

I thought cabinet makers had a jig for drilling corners?

Definitely make a jig to guide the outside. Also place a block on the inside so the bit doesn’t blow out the cabinet.

Here is my jig strapped to my alien star cab. made from a 2x4 with a 45 degree notch cut on one side with a table saw, then drilled proper spaced holes on a drill press for vertical accuracy. I later added the sleeves for durability and reuse-ability, but just the wood worked great for a one cab drill. On alien star (and most gottliebs) the holes are pretty close to the bottom of the cabinet and that thin plywood piece you see on the bottom made the holes the correct height with the cabinet sitting on my work table.

I’ll see if i can’t get the tech college my wife works at to 3D print me one. Otherwise i will just have to make a wooden one myself. Good excuse to buy a drill press

I printed this one and the hole is 3/4" which is too big in my opinion. I think it's a good idea if modified to the correct size.

I believe the correct drilling size is 1/2"

Ok i have an update! I know some of you guys have been losing sleep wondering about this cab and its lack of leg bolt holes....

A friend of mine (And fellow pinhead) had a thread going about converting a new stern cab over for a Sys 11 game, and completely rebuilding a head for it. Did a great job in fact. I had no idea he had those skills. So i send him a complementary text, and ask him what his thoughts were on making a jig for my leg bolt problem.

A few days later he drops this on my front porch:

Huge shout out to tomtest for making this up for me!! He even epoxied in metal sleeves to keep the bit from wandering. I’ve been procrastinating finishing this cab restore because of these holes lol.

Tom would like everyone to know his wood working skills are not for hire. But you should still go check out his cabinet thread!

Very nice! I was really happy with using a tie down strap to hold mine securely in place while drilling.

Yes i really liked how you did that. Going to use the same method to secure mine to the cab too
