We scrapped one because of a cracked block - frost damage. That one looks OK. Nice engine Richard

Technically, it doesn't. It measures straightness, roundness and concentricity. You can infer cylindricity from those figures, not measure it Richard

OFF-TOPIC When working on experimental Stirling engines, we used to get the pistons checked by the metrology department, including cylindricity. They always pointed out, cylindricity is something they couldn't measure. They can measure straightness, they can measure roundness, they can measure concentricity - but they had no 'cylindricity' measuring tool Richard

They're impressive, those blocks. I didn't get them to unpack the crankshafts they had in a box Richard

Did you enjoy Cov Classics? Richard

If that was some time ago, their whitemetalling man has moved to Coventry Classics. Richard

Apologies - you are right. I hadn't read the whole thread

Indeed. If it's a Marine JP you are going to have to take the flywheel off, and when you refit the gear housing you must get the fuel pump timing right Richard

Not really. There are several versions of the JP manual to trap the unwary. The reprints we sell have the plunger pump added at the back Wait 'til you try and work out a part number... Richard

Last time I dealt with a Fuzhou gearbox on one of the Kingfisher engines it had broken the spindle to the oil pump Richard

I'm warning against my idle, untested speculation. From the bits of theory I remember the engine is one mass/spring/damper system with the damping coming from mainly from the engine mounts. This system is going to have a (or more likely many) resonant frequency which is determined by all of those. You cannot change the mass, the springing and damping come from the engine mounts So, in theory, if you've got an engine that's going into resonance at an undesirable cruising speed, you could change the frequency by having different types of mount front and rear On the other hand - I'm speculating idly and R&D do this for a living. Go with the R&D set up Richard

Do they - and is that a good thing? After all, the engine can't wag at different speeds at each end of the block - it's a single solid item My guess (WARNING) is you end up with a different resonant frequency for the complete engine. And it might be that you completely upset the resonances in the setup to your advantage I've never done it, I do wonder if different stiffness mounts front and back would be a good thing Richard

Oooh no - that's not right Things go wrong, and they still go on running Without engine mounts Richard

Attached to what - a skyhook?

Kick the pin a couple of times at 90 degrees, then pull it out using the mooring line through the loop Richard

We sell them fairly often along with the metal cased lip seals Richard

OOh, no. Not horses Sheep! All we like sheep Richard

Sure? And where have you been for the last couple of days... Hannibal Lecter style I think I've got a large dog cage somewhere, would that be useful? Richard

The tub says add hot water Richard

'Ere - you've nicked my duck! I say mine - he joined Melaleuca at the bottom lock of the Delph nine. Looks like he's joined Delhi's crew Richard

In your picture, the data plate is just above the hydraulic pipe on the right hand side, below the sump pump. It's a brass plate Richard

I'm minded to take them to Braunston then sell them to the highest bidder Richard

It was, Daisy won! The queen with her crown was genius Richard
