Steve Bralla used to make and sell tools used to help align the wing spar pin bushings during assembly. He contacted me recently and said he had lost access to the machine shop. He graciously offered me the opportunity to take over the product line, and I am now in production. I will add them to my website shortly (www.mmfabrication.com) If you need one, please contact me through the website.

And a big "Thank You" to Steve!

Mark, In 2002, I bought one from Spindleburger that shipped with my trailer.. I made my own "improved" version and sold the one I bought.

Mine was made of black Delrin (as is the original) with the reinforcement a pressed in stainless steel pin. I made the outer large diameter a bit longer and have that cross drilled at 0 - 60 - 120 degrees for 6 handle hole options total, though the handle is rarely used. The 3 cross drilled holes provide plenty of purchase for turning to assist initial pin alignment.

On the face of the handle portion, in line with the eccentric end of the tool, I drilled a small dimple, filled with white paint, it shows where the eccentric is when the tool is fully inserted. This proved to be invaluable when using the tool to show which way the wing needs to be moved.

best,
