Hi Joiner 8
I used a cheap bench grinder when I started out and learn’t to sharpen with it ok they are a bit aggressive on your tools. There no need to go for a Record just look for the cheapest one you can find they all work the same. If you can find one with a wider wheel that would be better for doing finger nail grinds.
I moved over to the ProEdge by accident when I set up Olivers Woodturning. I got the Sorby rep to come and teach me how the ProEdge worked, then decided to bring the display unit home while we were shut for the Christmas break (2014) just so I knew how it worked should anyone start asking me questions about it.
It has never left my workshop it’s so quick and simple and the cutting edge it gives is great. As it’s so quick to sharpen your tools your not temped to try and make those extra couple of cuts with a tool that is blunt, so improves your work.
But like all things it’s down to budget and with a bit of work the cheap bench grinder will do the job.
All the best
Ed
