Posted this over at VE. Though someone AK would benefit.
I recently was lucky enough to find a Dual 1229 and a Miracord 45 for next to nothing. I already own a great 1229 and figured I would use the 1229 for parts. The Miracord was a learning experience to get it up and running. The 1229 needed a cartridge carrier, a joining nut #218-150, item #172 (someone PLEASE) and a outer gimbal because the tabs for multi/single were snapped off. Made a joining nut that works until I can find a cheap parts machine. Ordered the cart. carrier. The outer gimble proved to be quiet a challenge. Clean breaks where they snapped off. I have used Xylene and Toluene because of the painting and restoration work I do on furniture and other items. Either chemical will melt plastic and I have used the xylene to repair broken dust covers. It actually welds the plastic and leaves no bonding agent between pieces. It works EXCELLENT on dust covers. The problem with any glue is that it leaves a substance between pieces being bonded that will always fail. Whereas Toluene or Xylene has a carrier that evaporates and leaves only the plastic itself that has melted and reformed. My thinking said this should do a good job on the plastic tabs on the outer gimbal. Worked perfect..... and I have actuated the single/multi lever multiple times and it appears it is almost as good as new. I took a small artists brush and cleaned the broken pieces and also the collar they broke from. Use a very minute amount to clean the grease or any residue on the pieces. Dab with a paper towel. Next brush Xylene on both pieces (collar and broken piece) and let set about 20 seconds. The first application softens the parts edges where they broke. Again apply Xylene and let set for 20 seconds. Apply a third time to both and join together (if in fact you see the edges have dissolved or softened enough). It's a very delicate procedure to get them to align properly. NOTE!!!!!!! DO ONLY ONE SIDE AT A TIME!!!! The plastic will soften and then begin to firm up fairly quickly. After both sides have been repaired, firmed up and appear to be almost solid take the artist brush with Xylene and start smoothing the plastic collar (inside and out) where the repairs were made. You will see black plastic starting to melt and actually come off on the brush. Keep using fresh Xylene to smooth collar. This is also important because of small minute holes in the repaired cracks. The additional Xylene actually will soak into these hole and further strengthen the bond. I absolutely take no responsibility for those who try this. But it worked GREAT for me! I did have single breaks on each side and it involved only one piece per side. I'll be happy to answer any questions.
