Ripster cut his rubber sheet to mod his and rearranged them to get the weights he wanted where he wanted. I'm not sure you're going to be able to find a uniform weight sheet without using another board as a donor. at that point, you might as well just buy one that's uniformly weighted.
The "Ripster repair" I'm talking about is when his dog tried to eat his spacebar, not the mod. His mod article confirmed, though, that the weight is all in the sheet.
My whole point is to investigate whether Topre, directly or indirectly, ever sells parts... We could order replacement sheets - possibly for boards they don't even sell in our market. Imagine being able to buy an 86U, then mod it to uniform 45g with a $10 sheet of rubber mailed from Japan. That beats sitting here in North America, looking at UK suppliers, pining for them to carry a 45g 87U for only $350.
Then there's the whole issue of replacement keys for shinyness or damage.... One supposed feature about these boards is their long, long service lifetime. It would really suck to have to throw it away well before the 50M keystrokes (or whatever) just because you cracked the J key and couldn't order a replacement.
