Hi X-Bird,
Those are great suggestions, thank you. I was considering welding that little sprocket on to the shaft, but it may be too much for my little welder. So I'll try your suggestion first about predrilling and using nail polish. If that doesn't work, yeah, I agree with you, there is clearly too much unsupported shaft. I'll probably buy new supports in that case and make an entirely new assembly for it.
As for the support bearing on the end, that may not work because the sprocket is so small that the chain would likely rub against it. Maybe if there were a small collar and then a support bearing, so it wouldn't rub against it. Really, I wish they had a wider selection of jack-shaft sprockets; 10 tooth to 20 tooth is less desirable than say 20 tooth to 40 tooth. Even 15 to 30 would be better.
Thanks for your reply!
