alloy rods - anyone tried them yet?
new product at Frosts:
http://www.frost.co.uk/item_Detail.asp?productID=9220
If I understand correctly, they are like lumiweld/technoweld but easier to use.
wondering if anyone has tried them?

I'm interested as well, I have been considering trying this when I get around to doing the cut&shut on my efi plenum.......

I've used the Technoweld product and it works very well.
Main problem is getting enough heat into the workpiece. Bigger parts are very difficult to get hot enough for long enough. Aluminium conducts heat
very well and the joint area cools too quickly to melt the rods.
I think you'll have difficulty with the EFI plenum - it's way bigger than anything I've ever done. I would suggest finding a local
TIG wleder who'll help you out.

Interested in the manifold approach - any pics + more detail on the construction would be appreciated.

We used lumiweld to fit some lugs to a bike frame and they were still on two years later when the bike was sold. Welduk sells some stuff
here that's supposed to be even easier to use.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Nice work Mark.
I'm pleased to hear it's possible to do bigger stuff and impressed with the quality of your work.
What sort of temperature did you set the oven at?
The Technoweld rods should melt around 300 Celsius (I think) so I guess you were set at the upper end of a domestic oven range - say
220-240'ish
Did you take any precautions to stop the manifold cooling once you had removed it from the oven?

hmmm, 300 degrees ...... mine has a special mode that will take it up to something like 350 for cleaning. If i could just override the locking
mechanism this could get interesting!

I bought a bernzomatic blowlamp off ebay the other week and on mapp gas it will melt aluminium, so it should be up to alu brazing. The HST2000 or
whatever rods are used at 270* according to some reading I found on them.
