The angle will be fine, Im around that, but my grit is too coarse.. the grinder is a standard, around 28001/min, with this 180 grit diamond wheel. I could try to hone it ba hand, but im too newbie to even try that.You definitely want the wheel grinding onto the edge, not off it.
I use a 1500 grit flat disc at 400rpm for general scraping. What angle are you using? Try to keep 2-5 degrees negative or so.
I agree with PeteBlade is definitely not sharp enough. It looks like it's skating across the face. The multi-line scratches are where the iron shavings are rolling under the edge of the blade.
How are you sharpening?
Don’t forget shrinkage!
Great to see you're back on this @Pete. Looking forward to future posts.
I’m sorting it for Pete and putting it in with one of my orders so hopefully £150Great work on the cast mould!
I am interested to know what that part will cost to get cast.
I am also pretty interested to know how much it generally cost to get one off parts casted in the UK.
Get it in a small crate or on a pallet we can ship it no problem. We are customs agents as well these days which helps.80KG - no I hadn't![]()

Ah, not just pingfeckits, expensive pingfeckits! The vacuum bags for shrinking clothes are handy, dismantle inside one to trap the PFs when they make their desperate bid for freedom... they can even be gagger taped - oops, GAFFER taped (Freudian slip there) in place when driving complicated parts out.OK so I found out why some other machines have a little control knob on the gearbox and others don't. The control knob is a reversing control for those rare times when you might need to run the mill in reverse, it allows the feed gearbox to turn the correct way with the motor running backwards.

This machine has a nifty double sprag clutch system where one clutch works directly on the gearbox and the other is driven through an idler gear so it does it all automatically. Turning the input pulley anti-clockwise causes the lower sprag to drive and the idler-driven upper sprag to slip and the gearbox input turns anti-clockwise. Turning it clockwise causes the lower sprag to slip and the upper sprag to drive but because of the idler in the train the input shaft still turns anti-clockwise.

I have to replace the rollers and needles in one section of this because they are worn out from constantly idling (and low oil level). Oh, and if you're reading this and considering taking this lot apart - clean your bench and floor first because the needles and rollers fly out everywhere.
