There are times when you need to be brave and part off, and times when you pick the quicker and less stressful option and grab the hacksaw! For me personally this would be one of those times. I've made a small bit of wood that fits snugly over the bed under the chuck to protect it for exactly these times.

Maybe they were put off by the previous comment and didn't want to deviate this thread off track, or decided not to engage as sometimes it just isn't worth it when the person asking has been disagreeable to converse with.

Thank you

If the mileage lines up then maybe there isn't any skullduggery at play. The MoT's could be because someone was trying to correct a pesky fault, like emmissions. But it does suggest it has had niggles in the past. Could be fine now of course.

My grandad complained for years that I had nabbed his good phillips screwdriver when we were restoring my Morris Minor. About five or six years later I took the glovebox out to get to some wiring and there it was, tucked into something holding a clip back. It had done about 35,000 miles jammed in there.

That isn't a rare car; if thats the model you are after there must be a hundred out there that don't have black marks over their history.

Personally, if in doubt, walk away. The dealer will have an explaination, but what dealer wouldn't?

Ah, thats cunning. Thank you

Whilst idly browsing the internet I found mention of Rex Tingley's Valveless design of locomotive.

I can't find mention of how he achieved this "valveless" operation. Can anyone enlighten me please?

Hopefully this link will help. They list the designs there that they have plans for.

I worked for Boeing, and yes we did.

Do you need to cast the bores in? Could you leave one or both out of the casting process?

I've not long finished a 3" Southworth pump from blackgates, purchased a few weeks ago. I can't speak for others but it was quite swiftly dispatched in my case.

Was a pleasure to build.

I know its a lot flimsier but I remember the feeling of horror when I first saw a Seaking taking off from up close. As the tail rotor takes up the torque the tail boom flexes slightly, and all the rectangular rivet arrangements on the tail boom deform enough to make it look like a diagonal line has been scribed from one corner of the sheet metal to the other in each "box".... hard to describe but you would know it if you saw it. It makes sense of course, but still unnerving!

Some sort of industrial mimeograph machine or similar? The belt drives are intriguing?

Did you already see the PDF downloads here?

EDIT - just noticed the PDFs are not there, just tells you to go find them...

You say it had eased itself back to normal; are you saying then that it had physically stopped turning? I don't think the viscosity of the oil is the problem here.

If the lubricator was of the oscillating type (not sure of the exact name, but the type LBSC used to specify) then the cylinder would have just lifted off its seat if it was blocked; it would have still kept turning. If it is of a less forgiving kind then a physical blockage or stuck valve may have caused it to jam solid, but I would suspect its the ratchet or clutch giving you the issues here. Failing that, a mechanical issue with the pump itself. But in my opinion (and I'm still very much an inexperience amateur) I don't think the viscosity of the oil would cause the issue you are describing.

I suspect the pump body itself had something in it which caused it to jam.

Looks great Steve, nicely made.

Their school also teaches them about finances, pitfalls with finance and such. Why oh why oh why can't they teach them something useful instead, like Latin, playing the recorder or how oxbow lakes are formed.

They teach those things at my kids school, albeit CAD rather than technical drawing. I guess it rather depends on the school. That means we get the chance to pass on our skills.

What a lovely piece of work, well done.
