Hi guys,

This is a very interesting concept i worked on a few years ago with a few problems popping out, the biggest one was opening the computer when it was cold.

Humidity is not a problem...

I love the brute force approach :D

First check if it works and install a recovery filter.

According to what more experienced guys say - yes.

But you have to remember that the amount of HF that will form is small and has a lot of surface to corrode - think of this as a steel pipe...

Hey there,


About the HF acid forming problem - you could buy a special filter which is normally used on acid contaminated systems after a rebuild. I think it would do its job in filtering,...

The exhaust manifolds runners are 38mm ID, 42mm OD. Thats about 1.5". The exhaust valves have the same surface area as a 37mm circle so the exhaust runners if anything are too small for their length...

4x4 from a Sierra, 66% rear, 34% front, LSD read diff,
New suspension front / rear (mcpherson strut on the front using rose joints, independent double wishbone on the rear using rose joints)

The cams remained stock (248*, 9mm lift), if i haven't sold the sierra i would installed different ones, the engine was intended to rev to 8000rpm.

I heard about the back pressure theory a lot,...

Hi there guys!

I think some of you noticed i don't play with overclocking or cooling no more, its a little sad really but i no longer have fun in building xtreme coolers any more.

Maybe if...

I remember being hit by 110 and 220V. 220V is much nicer ;)

R508B is a mix of R23/R116 46:56

Hi there guys,


I'm in the middle of fixing my trusty old cascade and i ran in to a problem with the head exchanger and torch. I have no access to a oxy-propane/acetylene torch and my old MAPP...

Hi there guys,

I once experimented with automobile fuel injectors, you can buy ones with banjo fittings on the inlet and a copper oring on the outlet side. I don't think even adapting stock...

Teflon based seals could help with the Oring problem, at least as long as different thermal expansion rates of Lexan and Copper wont chew the oring away.

That's a really mean machine you're building there.

I love the heat exchangers, would you be willing to share with us the technique you use to coil them so neatly ? Or is it just the fact you're...

I think a mixture of nitrous oxide and hydrogen would be better ;);)


I think i saw once in Poland mixtures of N2 and H2. It was used as a inert gas for MIG welders. Gotta check it out next time...

Interesting. Does this gas mixture have a name ? Is it commonly available like CO2 + Argon mixes?

If it sits in the "sump" it shouldnt do any damage. Leave it for yourself as a bench compressor or sell it to me dead cheap, i always wanted to have a go at dual stage compressing ;)

I'm sorry if i broke the rules. This wont happen again.

I did a search on safety, looked for it in the forum stickies, and made a search for it. Only one result for the first 10 pages. I...

Hey

i used to use propane as the shielding gas, set at a low flow (flame about the size we get from a firelighter) and lit up at the evaporators exit, the propane feed was routed through the...

Thank you very much for your help!!

Hi there

The victim i was asked to look at and help with wirering is a 3 Phase Tecumeseh compressor. It lacks any starting equipment and connectors.

It has 3 connecting pins, C, S, R like a...

Thank you Michael.

Maybe some scaling up would be a good idea if i were to find some decent parts ;)


A little OT on refrigerant soak in to the oil.

When i began to build phase change...

R14 has problems with oil, to be more precise it carries a lot of oil and with time passing by clogs the evaporator. Afaik you can use silicone based oils, maybe experiment a little with propane and...

Incredible project, reading this thread was like reading a good book, i couldn't wait for the next page :)

I also found out that my theoretical thoughts about auto cascades were proven right, and...
