If I remember, the ratings are for 100% load capacity upright, about 70% sideways, and about 30% upside-down. If you look at the static and dynamic load ratings for y our SBR16 blocks you'll see they far exceed the weight of each of your axes - and you'll have four per axis.

A work bed is nice, and sacrificial piece of MDF allows you to cut through leaving nice clean cuts. Also allows you to easily fix work pieces on by simply screwing them down. Some Bondo and work board surfacing makes it like new again.

Thanks Louie, that helps a lot. It helps that I have a lot of materials to work with, so Aluminium 10mm machined base will go in and then an MDF spoil plate for the time being

Cheers,
