If you can think of a way to tension the blocks without using sliding bearing blocks, you can use unpocketed 1/8" tube to support your bearings. A lot of teams ran cantilevered wheels off of Toughbox Nanos last year which are made of the same stuff. This could save you a little weight and a lot of strength considering how aggressive your pocketing is around the bearing blocks.

I don't understand that part. We use sliding blocks in 1/8", what would the issue be?
In fact, we use 1/8" purely because of the sliding blocks, and it's usually the only 1/8" on our robot!
Every single team in FRC has had a rookie season. All those... have stories. Some are sad, some are funny, some are inspiring - but all the teams have stories to be told... Each year is a chapter in the team's history book with stories to be told and shared. - JaneYoung [more]
