Well I've started and it's all Mike's fault for extolling the virtues of cabinet scrapers so I managed to get hold of a Record 080 which is great but I really, really like the look of the Stanley 12.
Materials will all come from my stash of stuff, hopefully I can make the blade from an old circular saw blade so nothing lost if it doesn't work out, I could always have another try.
Only had 3mm steel so that will have to do for the base and sides, decided to cut dovetail joints after all how hard can it be? Wish I hadn't as I really struggled in metal to get them close so the joints need a bit of work though it's solid enough I'm not happy with them. I will need to weld some parts so might try a bit of filling, not sure yet.
Anyway this is where I am so far, I'll keep posting progress, warts and all if anyone's interested.
