Wax?? What A great idea. After sitting in class for A couple of years to become A Dental Lab Tec and working with wax I never gave it A second thought for my hinges, shame on me.
I figured A photo was worth the trouble so I went out and tossed A hinge together so you could see it, something about A 1000 words.
I cut the slots and trial fit the controls surface so it is all lined up. Install the hinges and controls, ailerons or stabs then drill the hole for the tooth picks. I cut the picks taper off. I will be using wax from now on but have been using oil on the brass pin for years. I drop about two or three drops of medium CA in the pick hole and it flows along the hinge all by itself so I don't put any glue on the hinge itself. Insert the pick and move on to the rest of the hinges. I try to only drill the pick hole through the hinge about half way through the wood on the other side to keep the CA from flowing out the other side. I do everything from the bottom so you can't ever see the pick bump, even after sanding they tend to show A little after covering. Cutting the slots takes more time then installing the hinges. Also showing you two types of hinge slot guides, on the left is for hinge pins and on the right is for flat type. These are used so you have your hinges centered perfect. Good luck, it's easy!!
