More grinding
I’ve been sent a couple of useful links on grinder jigs that you can make.
There’s also a useful book in the Workshop Practice Series, called Tool and Cutter Sharpening which describes lots of different grinders and some instructions for building your own jigs.
And you can also buy part kits for Quorn, Kennet and Worden grinders.
I’ve found an even more expensive tool grinder, a second hand “JONES & SHIPMAN 310T TOOL & CUTTER GRINDER” for £5500 from BWMachineTools
