[AT] haybine roller repair

[szabelski at wildblue.net]

OK, looks like the material is now available commercially. Turns out they now have several competitors who have been cutting into their product line and military sales.

The following are made by Raychem (TE Connectivity) who at one time was sole source to the US military because they were the only manufacturer who could qualify to meet all the nuclear, biological, and chemical agent requirements. 

S-1125    This is a two part mix that we used to use for sealing cables and filling in gaps and such. You get 5 packs, 10 ounce each, plus mixing cups and sticks for about $110.

RT-555.   This is an adhesive tape that melts under high temp that we used for sealing cables. You get 25 feet for about $90.

Like I said previously, expensive.

Subject: [AT] haybine roller repair

Anyone here ever successfully repaired any rubber covered 
rollers--specifically ones on a hay conditioner? Seeing some cracks, 
loose areas, and even a chunk or two missing out of the ones on my New 
Holland haybine. The machine isn't worth sending them off to have 
recovered. Looking for any repair methods that actually work that I can 
do here. I've had things such as FlexSeal, bed liner paint, vulcanizing 
cement suggested. Wonder if the vulcanizing cement would be the best, 
especially on sealing up some cracks. McMaster carries some urethane 
casting compounds, wonder how that would work?

If you have any ideas, toss them out there.

Thanks,
John Hall
