I have been using Elmers wood glue (is this a mistake?) Thane: In answer to your questions on glues for flange rebushing, I suggest that any wood glue is suitable if properly used. Especially when gluing felt, the amount of glue is very important. Flange bushings will work fine without being glued in at all; however a light gluing makes them less likely to be pushed out when pinning. Renner flange bushing cloth is the only type I would ever use. It is extremely dense, making for a very solid bushing. It has a nice strong "shoe lace" type point on one end that's easy to pull through the parts without breaking off. And, it is also pre-glued on the back side. To rebush, just pull it through the part, leaving about 1/2" of the end exposed. Then apply a light coating of moisture (read: spit) to the back side--enough to wet the surface but not enough to soak through. Then pull the wet portion into the part, and insert the correct size centerpin for clamping while it dries for 10 minutes under a lamp. The moisture activates the existing glue coating on the cloth; no additional glue is required. A certain percentage of the time when pinning, the pin will catch the bushing on the far side and push it out. To avoid this, insert a smaller pin through the bushings and birdseye to act as a pilot. This small pin is easily (and safely) inserted by hand, and holds the parts in alignment. The actual pin is then pressed into place, pushing the pilot on out the other side as it goes with no chance of catching the bushing. >What is acceptable for the tech. exam? The type of glue you use is not scored, only the end result (neatness, trimming of cloth, firmness, flange friction, etc.). If you use white or yellow wood glue instead of the pre-glued Renner cloth, be sure to use only a trace so there's no chance it will contaminate the inside of the bushing or the sides of the shank fork. For step-by-step instructions on this and other field repair jobs, see the PTG Technical exam source book, and the new PTG book, PACE Technical Lessons 1-7. Bill Spurlock
