Is this the answer to a Lambda block's prayer?   The video looks very impressive and I wonder if anyone has had any experience with it.

Amazing demonstration video.  

I've got an early Alfa 750 block that is U/S with a head stud turning - looks like this technology could be a much cheaper, easier (more at-home) way to fix the problem than a full strip down and machining / heli-coiling at a shop.  Might give that a go.  Looks like it could take the tension of a head bolt, and if it won't I've only wasted 25 and the cost of a head gasket.

I bought the kit from Frost, read the small print you have to heat the item to be repaired
and you certainly can't get enough heat into anything bulky with a blowtorch.

I gave it up as a bad job, after several rather futile attempts

Would you call an engine block bulky?

Shame.  If it sounds too good to be true...

I'm sure it wasn't being sold by Laser when I saw an actual demonstration at the Silverstone Classic Car Day 2 years ago, doing exactly some of what was shown in the video, including repairing threads in aluminum using only a blow torch, somewhere I have the spec sheet for this product and it has a low melting point for use with the  blowlamp, but it was as strong as shown once repaired.
I think it was a couple of Germans who were selling it at the time, and there were a lot of mightly impressed people.
I'll have a look and see if I can find the spec sheet.

Further research.  A pdf is available at        http://www.lasertools.co.uk/news/pdf/4707_PIS.pdf     The melting point of aluminium is 660C so the block would need to be heated to 400C.   I guess you could do this with an oxyacetylene flame but it would be safer to find someone with a big oven.  The demo is on a small block not something the size of a Lambda and I would be very nervous of melting the block itself.  I will have words with my local wizards and report back.

I saw the coke can demo at a model engineering show.  As quick and easy as in the video - if you ever needed to repair a coke can  Wink
