Andy Pickard, a turning mate from Devizes was bending my ear the other day to try out some Yorkshire Grit, all the way from God's own county (apart from Otley which he said is a sh*te hole ) so I thought I'd give it a go. I found a pretty nondescript and uninspiring bit of English Walnut which I mounted in the lathe to turn the inside and part of the exterior:
It was then sanded to 240g only, and a sealer applied (I used Polyvine matt acrylic) after which a dab of YG was applied with a paper towel all over with the lathe stationary:
It's then burnished using the same paper towel with the lathe running at about 500rpm. As the YG cuts, it makes a 'hissing' noise which gradually diminishes as the abrasives in the paste gets broken down leaving a surface equivalent to a 600 or even 800g finish. Any excess is then removed with another clean paper towel at a slightly higher lathe speed of around 800rpm:
....after which you can apply a finish of choice:
I reversed the bowl in the chuck using the Ax Wood Jaw Plates to turn the underside and foot:
...and repeated the same process with the YG and wax:
It's good stuff, even if it does have to come from Yorkshire - Rob
