That´s good to know mate. I really like your Ami, so hoping to see it running next summer.

So, what's it gonna be? Bookends or paperweights?

I'm not sure, but we must think along similar lines because I was wondering what I could use them for!

Maybe not a cheap option but it may be possible get them welded. After they are cleaned up machine the cancer away and substitute missing meat with a copper gasket to keep same compression ratio

I didn't realise they could be repaired like that, although I have a budget of almost nothing (I say 'almost' because I know there's some change in my trouser pocket I could put towards it) so I couldn't afford to have anything like that done, plus i have a load of engines for spares I don't really need to.

Well, I would most likely only do that if it was the very last head on earth.

I have a head with a stripped plug thread, I know I could have it helicoiled but how good is that? Is it as strong as the original ally thread?

I wounldn't use helicoil but an insert or get the hole welded and cut a new ''original'' thread.

So this evening i have stripped another pair of heads down to be cleaned up. Apart from a slightly out of shape pushrod tube these look fine. I'm taking the barrels in to work tomorrow to be shortened by .50mm each, and I'm going to have a stab at lightening the rockers. This will probably make absolutely no difference and/or I'll end up with a selection of scrap rockers to go with my selection of scrap heads and barrels, but it keeps me off the streets eh?

Next question, can anybody give me a list of what I'd need to throw that old tin-top box away and replace it with an LHM disc box? or, can I convert a disc box drums and use that instead? I want to use a light flywheel and isn't it the case that the drum boxes are the type which have to be used with the heavy flywheel?

You can fit drums to a disc box-you need to fit the drive flanges from a drum box to it but I *think* that's it IIRC.


(Oh, and the drums, wheel cyls etc would also be good I guess!)
