lol so had I. What do you expect on a Saturday night?
Sorry Gollum, I'm way too touchy. I don't drink at all really. Maybe I should start, I'm sure I'd be a much nicer guy then.
Chilly's heads are all 'round the best. I'ts not just cos of his name either, but the design is ideal. The stepper that dave uses is ok, but it's not as effective in 'case mount' or sideways mounting due to the loss of efficiency. In 'bench mount' it's virtually identical performance though. The spiral doesn't lose efficiency much at all. That's the main reason I like it better.
The mach head is just a waffle pattern in a small space, and funny enough it gains a lot of efficiency if you mount it 'on the bench' over a 'case mount' but most ppl aren't into having a bench covered in PC parts lol
The chilly tubes are very good for Dry Ice, as the temps move a little faster. The mousepot is far better for LN2, as the mass makes it so your temps stay where you put them and don't move as fast, but for Dry Ice they're just too hard to get to temp. Jason said it himself about his tubes. Still good, but not as ideal.
It's all about what you want I suppose. For Phil, the Chilly head is ideal to offer for a conversion as it works as well in a case as it does on the bench.
Baker's head was great, but really it's the same deal. His design was even better on the bench than chilly's but fell a little flatter when side mounted.
I mean, you're only talking a couple degrees of loss, but every little counts.
Ah well, I'm babbling about it, you can tell I've bee researching the benefits of each head design, and the physics behind why lately. I need to get out more.

No worries. I see where you were coming from and I was in the wrong. No hard feelings.
That's some good info on the heads btw.

A little off topic - but surely it can be copied? or made different enough locally without infringing any rights?
There are loads of engineering firms in the midlands (local to me) that would be more than happy to run a few off (probs 10 minimum) at a very reasonable price.
Of course there was 'HOOD' who came over here from wetandchillychips who alos has some CNC equipment.

There's a bit of a question mark as to whether his is copyright or not. He says it is though so I respect that. I'm assuming he's patented it and just leave it at that. The spiral is his.
There's plenty of other designs though, and I'm still revising mine so it's viable to machine at a decent cost, but we'll see about that.
When you take into account materials, machining, and the mounting system itself, it's really hard to get the price down to the point where it's cheaper than just buying one from someone who get's larger runs done.
You can check into it, but after looking at it myself, I'm struggling even with the small independent machinists who are willing to do it on the cheap.

IIRC you would be able to copy some sort of basically similar design, but Reggie has implemented several changes to increase the surface area to make the heads as good as they are today, and i dont think he releases the drawings of the evaps now to avoid people copying it.

Just a thought on the whole copying idea reggie uses a right hand thread it it were a left hand thread would it be a copy no
Also as for costs yes they do seem expensive if the mods were done on mass basis the cost would be less instead of buying individual parts as you know you can get the basic head and mounts landed on your door for roughly £100 odd then you need the gas the brazing tools vac pump and time,an a/c engineer would charge £25-40 an hour a modification and tune takes roughly 12 - 16 hours to now you do the math

Exactly - you need to do it on mass and you're the only a/c engineer I know. So perhaps you and Phil should offer some cheaper heads which you (or someone else) could mass produce and sell. I'm sure EP is big enough to make the cost smaller than chilly1 prices.

Or work with ECT to have the Mach2 units come with better cooling heads as standard, a sort of interim upgrade before the Prometeia Mk3 comes out.
