Hello to you all!

Long time reader, and I hope soon to be builder.

Just have a quick question.. You lot seem to hate/dislike the "V Wheel" way with V bearings and steel profile as a linear guide.
Over at other forums this seems to be the preferred option..

And the supported round rails often get shot down aswell.

This has me looking at the hiwin type rails, but I dont really think I will need it!

What would be the stronger option between supported rails (for example SBR20) and the v wheel solution? Using the standard w2 wheels with 3/8" bore. I realize that much depends on the steel profile, but for the example lets say you use perfect hardened steel in 90degree angle for full contact with the wheel?

The machine Im planning should work with hardwood and plastics.. But overkill is always better if something else shows up!

Thanx
the madman
