Thread: New 72x2 Grinder WIP in Aus.

Thought I might as well do a progressive post for my grinder WIP
So some of Aussie member may benefit from sources etc
progress so far

1st I spent the last couple of months searching the net for every grinder I could find to plagiarise for my design.
I have narrowed it down to a couple of design options,

My final design criteria is as follows:
VFD operated - for more control
Direct drive 1.5kw/2ph motor - 3 phase
8" & 4" wheel on a swinging mount
A platen between the wheels for flat work
a small wheel attachment with a 2", 1" & 1/2" wheel options
5" drive wheel - crowned
3" tracking wheel - crowned
Strut Type spring -15kg/33lb
50x4mm box section body & arm mounts x 3 off
40x5mm box section wheel & tracking arms

finally budget about $1300 Aus.

I have done a couple of drawings for design scale etc

motor -$ 185 delivered Connon motors in Victoria
VFD - $155 eBay seller 2 year warranty ( the rest have only 1 year for $137)
