What intrigues me about these things is that someone knew both engines well enough think the two halves could be mated.
I wonder if anyone out there is making dog slow K1100 engines with Austin cylinder heads?
For every Triton, better frame and better engine, there's the possibility of a Norumph. The latter occasionally come up on Ebay as a Brit bike special, and presumably get sold to the gullible who haven't done their research.
We did indeed, ******** if i can find any photos of it though.... i know they exist, because i can see them in my head (maybe on your fb? cant be bothered to look especially), me preheating with the oxy propane, then you welding.... weird? Only thing ive add to whats been suggested, is to make sure it cools slowly. I built a insulated box full of vermiculite for another job (definetely for another job, 100% didnt spend time at work building a box just for my cylinder head, no sir, that would be wrong.....) which it went into immediately after we'd finished. was still nice and warm 12 hours later, so defo will have cooled nice and slowly.... to be fair, if youre anywhere nearby, youre very welcome to borrow the cooling box, id need it back after though, it does actually still get used occassionally!

a local guy here did that and made his own 16vlave head for it , it won a few races i think , cant remember his name at the moment , but I will , he was a local engineer.]

For slow cooling I've got a fibre glass welding blanket and a Hot water tank jacket to wrap it in, hopefully that will be enough ?
Thanks for the offer of @sasquar but I'm a bit far away from you.
With Tritons etc my personal favourite was always a Norvin, the featherbed with a Vincent engine. Saw a really nice one for sale in Sheffield at 'the bike specialists' when me and a mate went to pick up his new bike.

yep, still needs a final skim when i get one of those 'round tuit' things and finalise the build details......
@Popcorn no worries, couldnt actually remember where you were in the world, your quite right, geogrophy is not our friend on this one! Im sure that your welding blanket and jacket will be more than adequate!

Will do, blocks just about done just waiting for one more set of plugs to be machined to fit.
Stripped my gearbox and sent the mainshaft of to be ground down and a new bush made for a pinion support bearing housing.
Have you looked on Turbominis ? There's a lot more information about this conversion on that forum. turbominis.co.uk
Also check out Turboharrys website. harry.htm

Is there not a bearing that fits the end as it is - or are they not uniform enough in size here?

if you look at the welded head it has been peened that helps to get rid of residual stresses it easy done immediately after completion of the weld

Progress yesterday finally welded the head up, the amount of contaminants was unbelievable. Had spent ages cleaning the head, grinding out the water ways and finally giving it a wipe over with acetone. Warmed it up for a good 40 minutes on the camping stove, set the r-tech to 190amps, 40% cleaning, 2.4mm tungsten and 2.4mm 4943 filler rod with 8lpm argon. Probably would have been better with a 3.2mm tungsten but the garage gremlins seem to have had them away, anymore cleaning action just melted to tungsten into a massive ball.
