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.

If you went single stage with that HXT it would still fit between the cranks.

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.
