Several for me at different dovetail angles and a couple going to the states.
I’m going to surface grind a master prism to scrape in the angle
Heat treatedCast iron ? Are you going to weather them or have them stress relieved ? I have being trying scraping recently, oil flaking especially, not easy but not incredibly difficult either.

Heat treated
Scraping is easy ,correcting geometry and adjusting geometry for sag and droop takes skill
I think a lot of people are doing cosmetic scraping which means nothing or scraping in a cross slide but it’s pointing in the wrong direction.
I’ve said here before doing a apprenticeship as a machine tool fitter was probably my worst ever career mistake and Im still bemused by it almost being trendy and gutted that I sold most of my stuff for peanuts before it became trendy![]()

I made this today, not quite finished but just about. I then have to make a couple of rollers for it so hopefully I can do that on the CNC lathe if I figure out the difference in the codes from the old control to the new one![]()
It is a bow roller, goes on the front of a boat and is used for lifting the anchor to keep it away from the hull.what is it / what's it for?
Scraping is still used on class cnc machines and big plain bearings.Yes i have noticed that myself, its like the whole knife making thing, its a trendy lost art resurrected. My trade is fitter and i did ask in the tech why scraping was not taught anymore, i was told there was no need for it anymore. But it is something i would like to know.
A few weeks ago I got a Hand Picture Frame Cutter.








, rather to cut a bit off a larger piece of mild and thereby potentially rendering it useless for the next 'project'. Had I just done that, the job would have been done in half the time.....
Schoolboy error 
] attacks of cramp in my hands which can be a result of the drug cocktail. I stopped there, as it's no fun working when I have these, sometimes even letting go of a tool can be...interesting.
I know I could have just used three mounting screws for the box, but if I have to head-butt it......

. I decided that I'd have a go at cutting the grass - after all, it wouldn't matter if i couldn't let go of the mower would it? And I can do the wiring another day, or if it's wet tomorrow 






A silly thing, saved from the rubbish bins.

This box, the contents and the box next to it have been dumped, don't start me on that.
The tools are long gone. But I found the box hidden in a local skip.
Sadly, the box was broken. But that was mainly due to worm.

The front was saved and cleaned up, the worm arrested.

Frame made, yes the wood was recycled, from a window frame.

The box front was cleaned and waxed with a hard wax. Bee's wax from a local bee keeper. The frame stained and waxed.
What I did not show was the little metal springs, what lock the wood together. Made from a broken band saw blade. They keep the front in the frame and will allow the different aged woods to move and stay together.
