| (...) If the material is failing, I doubt filling the holes will help (perhaps, *maybe*, with a very strong glue, but I still doubt it). The problem is getting anything to bond the plastic nearly as strongly as the plastic bonds to itself. I don't (...)

| (...) This time I heated it for 10 minutes and let it cool in tap water for a fair while. The gear lasted noticeably longer - almost to the end (it's operating a elastic wind-back mechanism). But then it snapped. The gears always crack at the (...) (19 years ago, 22-Jun-05, to lugnet.parts.custom, lugnet.parts.mod, lugnet.technic)

| (...) Bummer. My suggestion would be to "gang" more gears side-by-side. You could use metal gears, like meccano or something, but you'd always have a weak point at the plastic/metal interface. Or you could do all the mechanicals in metal, and just (...) (19 years ago, 21-Jun-05, to lugnet.parts.custom, lugnet.parts.mod, lugnet.technic)

| (...) I "doped" the gear and it still broke. I think it might have lasted a bit longer though. I put it in boiling water for 5 minutes then in iced water for 5 minutes. Didn't use it until about 15 minutes later. Any other suggestions? Jack (19 years ago, 21-Jun-05, to lugnet.parts.custom, lugnet.parts.mod, lugnet.technic)

| (...) I also have finished this set and I also like the boom extension, but the main problems for me seem to be that the boom extension doesn't move smoothly, and the outriggers follow the same pattern as the ones from earlier sets (8862, 8460). (...) (19 years ago, 19-Jun-05, to lugnet.technic)
