Drilling straight holes in spars

I recently purchased a Skybolt project. I have researched drilling straight holes in various threads and have seen some jigs, “U” shaped made out of welded material. Someone used a milling machine to make a jig out of aluminum. I am used to working with wood and have a pretty good wood shop, however I don’t weld, nor do I have access to a milling machine. Has someone come up with a way to make appropriate jigs out of wood? Are there retail jigs available that have been used and recommended? The jigs I’ve researched don’t look like they have the accuracy needed to drill necessary holes. I’m talking about 1/4” holes for ”I” strut, 1/4 “ holes for internal flying wire fittings, etc..

lower and upper wings have been built. I’m currently making wing benches as the upper wings need to be glued together. (I have Steen Aerolab backing blocks to glue wings together). The fuselage is complete and was professionally welded by Steen Aerolab.

Any help would be appreciate.

George
