Good bit of thinking re cam bushes !
Cant be much holding back the motor rebuild now ?

Cam bushes are reamed to size.

Clock it.

Cut it.

Tantalisingly close to getting the bottom end built back up. Waiting on some new big-end shells as the one's I bought previously appear to be 0.003" too big. Three thou doesn't sound a lot, but in engineering terms it's 30% bigger than what it should be.. Annoying to say the least.

You got some useful kit at your disposal there Will !
That will be one sweet ride, far superior to how it left Meridan !

Yeh, I'll second that!

Can't wait to see it.

Don't worry folks, I've not given up!

There are a few issues putting the stoppers on progress at the moment, which has pushed the expected completion date the back end of July. It's mostly to do with reproduction parts being totally wrong and having to rework a lot of it. Still. Onwards.

Sounds like a good thing - you've got 3 kids as it is ..............

WOW.. Such a long time since any kind of progress was made here.

But, that is all about to change as the 6T project is about to be pulled back to full bore, with the aim to have her finished for the end of July. That's little over 5 weeks away!!

So far, the crank and rods are at the machinists to be re-worked. Not the workshops fault, but more poorly made new parts. Should be picking it all up on Saturday morning.
The barrels have been bored and honed to size, so they'll be off for powder coating when I pick them up..
Engine re-build can continue then.

Still a few more things to get, such as an exhaust system.

More to come in the following weeks.

Great news will, hope it all goes well, as that is a tight schedule.

Spoke to the engineering firm who's doing the work on the rods for me. Turns out there are two compounding factors. The big-eng shells are a mile out, but so are the rods. Normally the issue could be sorted by matching the rods to suit, but the rods are already at the top limit. Bugger! So i've been left with no option but to buy two brand new con rods. At £140 a piece, that's a hell of a dent in the budget and will probably mean the paint job will have to wait a while longer. Still. At least I'll be able to enjoy some of the summer on it with a virtually brand new engine!

New rods fitted to the crank. You have no idea how happy this makes me feel.

During the week more parts have arrived, which means I can really get cracking with the engine build again. Once the 250 is off the bench, the 6T will be back on and the re-build will be back under way. Oh yeah!

Looking good !
Does my memory fail me or are those shiney new uns look a fair bit more substantiail than originals ?

Nice to see you smiling again Will, which also means we will be back to regular instalments, can't wait.

They are indeed. The same rods are used in race engines of similar design. I went for them for a couple of reasons. Firstly, they're about £60(each) cheaper than 'Carillo' rods and secondly they're used in race engines which sustain far more stresses than what I'm going to throw at it. Don't get me wrong, she'll be being ridden hard, but not as hard as a race engine.

Oh yes!

Yet more issues with poorly made parts. Yet again, it's a bearing that's the issue. Why bother making something that's wrong? What is the point? Grr
