Double Barrelled!

Standard

A fair mix of emotions yesterday when I found a Bristol Hercules cylinder on ebay. Great that parts are turning up, and I scored a barrel to compliment the Centaurus I already had.

But absolutely gutted to find the seller had a piston and sleeve, already sold!! That would have saved me some grief. I’m trying not to think about it. So close!!

Still, I have access to a complete engine in Donnington, a sleeve, barrel and a few heads so there’s a fighting chance of getting everything I need. Worst case, I’ll make a piston and get the sleeve I do have hard chromed and ground back to size.

They look like a pair of robots on the bench, almost have a personality if their own! Before anyone suggests it though, I’m not making a V-twin. It’s been done already!!

Shed faries…

Standard

The shed faries have been busy while I’ve been in London this week. Bob has finished the second flywheel and it’s really starting to look like a big end. A BIG end!

It’s just a mock up at the moment, nothing has been pressed in. But you get a good general impression. The next step is to line bore the main journals and crank pin hole. That’s a fair job in itself, the tracing paper will come out again for that.

We’ll try the faceplate to start with, but it’s a heavy weight to mount and spin eccentricly. Counter weights will definitely be required. For now though it’s worth admiring progress, the steel is very tough and Bob’s taken the job forward well. Thanks Sir!

Flywheel 1 down to size

Standard

Bob and I have been busy and flywheel 1 is now down to size. The thickness and diameter are to the drawing so its out of the lathe to make way for the other wheel. Once we have a matching pair they can be bolted together.

Taking the half moons out in the miller will be slow going as it’s tough stuff, but little by little we’ll get there.

I held the conrod up to the wheel to get a sense of scale. It’s going to be a monster of a single!!

Finished baffle

Standard

A good day is when you make something. Or try to at least. As the sun sets the world is a difference place, as something exists that didn’t before.

So a good evening round Nicks ensued as we drew a baffle on the laptop and set the machine to cut it from perspex. (After a trial with some wood). The long suffering Emma provided Pizza and by the time I rode home the big Honda had a new baffle.

Does it work? I think so, but it was raining and dark. I haven’t ridden it since either! But I’m ringing the bell as it’s not my imagination, definitely an improvement. It may not be the final version as its a bit thick, but it will certainly do for now. 🙂

Clear as Mud

Standard

Well perspex actually, or something close. A little job for the new VFR1200X Crosstourer (did I mention I picked one up recently?). Anyway, I did 🙂

A very nice man called Terry gave me a brand new screen for it, and a set of genuine Honda fog lights too! (More of which later). The screen is great but the third I’ve tried, and they all give a wind buffeting which is quite annoying.

Think of a car with one back window open and you get the idea.

The forums state that a standing wave is formed by air coming up through the gap where the forks go. I tried sticking my hand there and it did make a difference. Time to make a baffle!

I ordered some perspex from an online retailer, but when I turned up to collect it the industrial unit was empty! Lucky a nearby until made point of sale stuff out of various plastics and agreed to sell me some.

Thanks to Helen and the guys at Prestige POS, I might use your services again! Their cutting machine is a little larger than Nick’s!
