Thanks Nic 8)

So, I finished laying up first AV Bay tube last night and wanted to give the Sumo Slicer a go tonight. For those of you who are into fine craftsmanship, look away now!

Used some plastic conduit clamps? To hold the flexible attachment end in place.

Attached that to some wood and bolted it to a pivot point.

Used a bit of 6x2 as the SpaceManMat Sled and pulled the wheels off my spare shed chair, drilled some corresponding holes in the sled and used them as the Ramjet Rollers.

Once the Cryo Cutter blade was in place, cranked up the juice and let rip.

Lol, fantastic result. I'm loving the names you've given things, although I do wonder how many Jase Juices you drank before coming up with them? :D

That is an awesome solution!!! I've got to make myself one of those. Until now I never had a use for the flexible extension for my Dremel.

Ciao,
Mike
