Hi Ian

Thanks for reply.
Spindle 1.5kW or 2.2Kw depends on what profiles I use mainly 30x60 or 40x80 both IR.
Normally I would weld the frame, but time is factor here so will use extruded aluminium IR as quick and cost effective solution.
IMO Vallder profile is ok for 6040 size machine and light Kress.
I like your workmanship, attention for details. Please share your rc models job.
I do make mold for sailplane avionic panels.

Cheers
Tom
