DIY wblock - just drilled - pls. help!
 

I need your help people!

situation:

I want to make a wblock with tools I have, so the only way is drilling the copper block.

The thickest piece of copper I could find is 10 mm.

The block will be drilled on my pillon drill.

I'm not making a great performer, just want to make it performs as best as can.

the tubing is 1/2", pump is micro Jet 200 Gph, Lancia prisma heater core.

I dont have that much copper to try everything that crosses my mind, so this is what I'm thinking:

No. 1. all holes equal, 3 mm dia, base thickness 3 mm, connecting channels 7 mm dia

or...

No. 2. progressively bigger holes toward the end of the block, 3 mm dia, 4 mm dia, 5 mm dia, base thickness in the middle 3 mm.

Will this configuration make the water flow more equal in all the channels, considering lesser resistance?

any suggestion welcome!!!!

thanx !

If anything, you'd want to do the opposite of what you suggested in #2.

See this thread

Also, at the bottom of page 4, you'll find a link to a pic of a block by xjinn. You could make that.

Good God!!!

Thanx BigBen!!!
