Micro channel wb with limited tools
 

Hi, I’ve wanted to build my first wb for quite some time now, but I don’t have a mill. What I have is an old but sturdy drill press and an old and weak lathe with some extra functions such as mounting a small cutting wheel.
I’ve bin thinking on how to use this fore something else than a #rotor block, and I think I might be able to make a simple micro channel wb a bit like cathars block, but since I’m a newbie at working with metal, I’d like some comments on it.

My plan is to drill two large holes with a “flat edge” drill, and then saw slits between them with the lathe. Then I would mount another block onto it, and then drill between the blocks to create an O-ring channel. And then mount a plexi top on it. Do you think it’s possible to make it, and do you think it would perform ok?

Another question. Does a nozzle have to be round, or could it be rectangular?

No, the nozzle doesn't have to be round. In fact, we recently discussed a triangle, oval and rectangle.

Your pics don't show up for me.

By the description, drilling an o-ring groove is probably a bad idea, but otherwise, you've got a good design.

You could make only the base in copper, and other two layers in plexy, and try to leave enough place for silicone/goop/other sealing material (make it without the o ring, seal like #Rotor's block).

just thinkin'...;)

Cheers!

Why? Do you think the corners will be to sharp?

Does the O-ring need to be pressed against the backplane of the groove to be able to handle pressure?

Would it be easier to make the top in copper, and solder it on with silver solder?

i plan to have 9.5mm from the edge o the grove for my waterblock, should this be enough for a sealant ? (not an O-ring)

If that's your remaining option, yes.

Otherwise, you'd have a groove that has extra openings on the outside wall, and that's potential for a leak.

I dunno, maybe you could test it. Your main obstacle will be drilling perfectly straight in copper, which is hard enough to do. Personally, I wouldn't even try it.

Ok, thanks allot fore your help. I think I’ll try and do it without the O-ring, and see how that goes.

Cheers!

What kind of cutting disk are you planning on using, and where did you buy/ will you buy it?
