Recently bought an old jig grinder for planer/thicknesser & jointer knives...
Has a sliding carriage...
For lineshaft drive...but came with a 1/2HP Century electric repulsion start/induction run motor...
Yes I certainly do think you should use it....
Sandstone is a very gentle & forgiving abrasive for edging tools...works very well and the slurry generated hones beautifully...
Get some 2mm sheet metal and make a half round bath for it
A bit of 50X50 angle around the top....
A couple of pillow...
I've an early design of flashtapper...
Run upto 20mm tap...
I've got several mechanical hacksaws...and a lineshaft driven surface grinder...
Oh, and I've a pedestal grinder...a large one with a 18" capacity...thats for lineshaft running too...
They're OK for home use...not suitable where there's employee's...as you'd never get insured for em...
Like I says...theres minimum guarding (if at all), no instabrakes and certain types of cutter blocks are known for nipping finger ends off and throwing knives...
I take it you were one of those watching it
It was actually a bit more than £200
But I don't like discussing 'how much' on forums...nor anywhere else for that matter...
