TOS-KURIM CNC Upgrade

Yes, that's the right kind of voltage and current for the diode bridge - and CPC is a good place to buy stuff. A lot of their stuff is identical to Farnell (sister company) but inexplicably sometimes a lot cheaper. You need to bolt it to some form of heatsink but unless you plan to push the spindle to its limit and keep it there for hours, it won't need much. I just fastened mine to the steel backplate and it's been fine. I have something similar on mine which I scavenged from the original VFD in my 1983 Shizuoka.

I think I mentioned earlier that I repurposed a 110V site transformer for my machine. If you are feeling flush / tight for space, that's an option. https://www.screwfix.com/p/carroll-m...mer-110v/43658

Here's my transformer / rectumfrier / VFD installation. The relay next to the rectumfrier is a time delay jobby to allow the caps to charge over a second or two. The caps themselves are hidden behind my Centroid Acorn board further down.


For the caps, I used a couple of these in parallel https://cpc.farnell.com/vishay/mal21...P=TREML007-005. You could probably get away with one if money is tight.

That cap you linked to is FAR too small. It needs to be about the size of a coke can, speaking technically.

Here's my cabinet. No, it's not a textbook example of cabinet installations but it works.

Doesn't seem to matter what I do here, I can't get the photo orientation right. What's the trick? It seems to be using the iPhone metadata to determine the orientation.
