bolts have threads on the out side and nuts have threads on the inside :Doh:

just remember its righty tighty. and lefty loosy. unless its the other way

looks like you adopt the old fashioned engineering practices if it breaks then make it stronger , then the next weakest thingy breaks , then its over weight and and pulls like an Acto powered nissen hut :)

Ah yes, Lefty Lucy etc... works fine unless you're underneath the nut in which case it's Righty Lucy - unlesss it's a left-hand thread of course...

TBH, I find a good dose of oxy-acetylene cures most nut/bolt related problems. And a good fire extinguisher cures most oxy-acetylene related problems :palm: And if all else fails, it's out with the Birmingham Screwdrivers :hammer:

Which is when you add a turbocharger, or a supercharger (whichever you haven't already fitted). Or a bigger engine. Or even both... Of course, that's when the whole "weakest part" cycle starts again :zap:

I should probably draw the parts up in SolidWorks; I believe that COSMOS (which I have a copy of, somewhere) does stress/strain analysis, so i could probably use the CNC to lighten the bracket up again without losing too much strength. Or, I could have a beer. Hmmm Beer. :drool:

Have a beer....... I'm getting headache! :palm:

AdeV:
I have now "finished" the brackets (I may use the CNC to pocket them out to make them lighter in future - or maybe not):

So, the idea is, the big block bolts to the engine; the small one to the alternator. The stud is fixed in place in the small block, and passes through the slot on the large block. The inside flange nut (!) is then wound down the stud, pushing the alternator outwards until the belt is tight. The outer nut is then tightened against the block to make a lock-nut effect, preventing the inner nut from working loose (time will tell - but it's no hassle to put a 2nd nut on the threaded bar, if the single one tends to work loose.

Tomorrow, I will fit it to the engine and, all being well, that's another bug crossed off the list.

That looks rather nice, and technical. :thumbup:

Well done! :clap: :clap:

The last alternator belt adjuster I saw, was a curved slot, in a curved piece of 1/4" steel..... And the alternator was a dynamo.

Guess things have moved on a bit......... :)
