It's now a year later since I was active on the forum.
Wifey made me a present of polystyrene sheeting for my shed last Christmas. The upheaval of lining the walls and roof left the shed in an unusable state. and on it goes... I wonder if she was telling something? Anyway, now I'm back to running my redesigned in Aluminium Rockcliff model A.

I'm desperate to get a quiet as possible spindle that can handle bit sizes in the range 3/4" (1/4" shank) to 0.050" (1/8" shank). The 3/4" is a router bit and may only ever be run in my 1020W B&Q router.
I stumbled upon a series in cnczone (http://www.cnczone.com/forums/457977-post54.html) where a fine engineer (Herbertkabi) has designed and published his work.

He is adimant that he will not make spindles for others, so I'll just have to call in some favours with my colleagues and get help to make my own.

This thread is about Mach3 control of DCBLMs. If Mach3 outputs a PWM, is it reasonable to assume that it has similar parameters to the Radio Controller Modules??
In which case if it does, then the conclusion to this thread is YES.
