have a question about the aluminum block you've made,
how are you sealing off the top plate? do you make a channel for an O-ring and screw it tight or...
i've got a copper block, and copper HC, i want to make an alum NB block since i have access to alot of alu (no more copper ), just not sure how to mount a top plate, copper i can solder, i mean my dad can solder but aluminum you cant. im also wondering if i use an aluminum block and a copper block, it i will get that terrible battery effect ppl keep talking about.
thx

I just use clear RTV silicone, no O rings. Use some 400grit sand paper and sand the top a bit to creat some tiny channles for the silicone to settle in and apply a thin layer of it and tighten the screws. I don't know about the battery effect. I used to get a lot of slim build up but I started using methenol and it is pretty much stopped. I use brass heater cores and barbs with the AL blocks and don't have a problem anymore with the methenol.
