Cheers,

I've got a quote for the latest design, and the cost has dropped a fair amount, which is great.

I'm looking to start taking orders, on an ad-hoc basis, in the next week or 2.

I'd also think that the design (without a middle plate and slits) will be less restrictive. And i still think it will work great for pelts.

Yeah, it would be less restrictive, and I have now eliminated the middle plate, but some aspects of a middle plate are now built into the top plate, to save costs.

But as has been said before, restriction is not necessarily a bad thing, if it aids cooling. Just because a block is not restrictive doesn't mean its going to be a top performer.

And although you might be right about the pelt, I doubt it. The circles would only cover about 60% of the surface of the TEC, which is definatly not a good thing.

If you put a 45x45mm pelt on this block, you'd actually be able to see part of the peltier sticking out of the side of the block, not only not under the cooling section, but not even touching copper.

The design is easily adaptable though, just add more circles.

any vague estimates of possible prices yet? :)

ah, i wasnt aware the block was that small.
Of course - it would be good for pelts if you made it larger (more circles).

You are using a lathe, right?
I'd imagine that is much cheaper than machining.

Thats very much the point, machining grooves like the WW is too expensive for me.
