How did you get the second stage connected to the first stage or are the matex gears setup to stack? Looks like I will need to create a connecting rod between my two stages and was thinking I might need to have bearings on that connecting rod. I like the cooling fins you put in. I'll have to remember that when I do mine.
12p3phPMDC said:the matex gears "mate" together--1 side is female and the other is male it will not be easy to attach pulleys on these gearboxes--you will need to find someone to broach the pulley for you. you will also need bearings to support the sun gear. If you went single stage with that HXT it would still fit between the cranks.
kfong said:Thanks for the info, now I have a some idea of what I need to do. I still want to try putting them side by side. I like the setup as narrow to the frame as possible. I'll have to put bearing blocks for the sideloads and will use a freewheel and chain, but plans may still change as they always seem to do.
