On the subject of calipers vs. micrometers, the caliper is a good guide, but it is the micrometer, used only with the ratchet, that is absolute. Caliper readings can be aided by supporting with the right hand, whilst drawing the jaws together across the work with your left thumb and fingers. I...

Oscillators are serious engines, and were used in full sized ships such as Brunel's SS Great Eastern. This used screws powered by "conventional" horizontal engines, but the paddlewheels were powered by oscillators. It was the largest ship ever built (1854), only surpassed in size, forty-one...

Shipping shouldn't cost too much. BA is still very much alive in England, and Reeves 2000 sells fasteners of this type. They are made on sliding head automatic lathes, and their quality is a cut above what you can usually buy. They also sell "model engineers' special set screws" which are bolts...

Ha! I've got a mk1, just about ripe; the castings have been weathering for about 25 years! -Andrew

Derek, your need is noted! Another three requests will make it happen... -Andrew For all you other guys, have you started yet?

John's still around, and I'm sure he would have no objection, unless they start being copied. He still supplies them, you see!

Additional, and for everyone - I know that you US guys will have your own people, but for everyone else looking for pushrod tubing (and I have no commercial connection) the company is Coopers Needleworks of Birmingham. They hold an amazing range, and will sell by the metre. For those in th US...

The original plans were dye line prints, so keep 'em out of the light until you need them, otherwise they will fade and become illegible. I'm not sure how John C is reproducing them these days; the other guys here will be able to tell you... I had to chuckle when I read your sentence "when I...

Hello gpcoe! I'm sorry I didn't respond- I would simply not have seen your mail; it's not a case of apathy, I can assure you. The first batch was for five, the foundry made six (a common foundry stunt) and bearing in mind the cost of fuel there and back, anything less than five or six crankcases...

Thanks, Joe! I'll try to get some more of the conrods, cams, pistons etc. I'd forgotten how much I'd done!

All good suggestions. No one has mentioned Reeves 2000- very fast dispatch. Another good plan is to befriend a CNC shop. The "Multibore" collets modern lathes use cannot grip anything shorter than 2-3" long, so consequently lots of bar ends go straight in the scrap bin. Any jobbing workshop will...

Hello Bob! Where are you based? UK? -Andrew, [email protected]

Yeah, well after mucking around with that faceplate, I gave it to my Dad to use, and bought another one to preserve the set up for him. He's working quick on the project- it's only taken twenty years for him to start it! I've done my case, crank, covers, cylinders and cams. Still a long way to...

Thankyou for posting the photo, Joe... My camera has packed up, otherwise I would have done it myself. When I did the bores and screw cutting on mine, it took nine hours- four of which were spent on the faceplate set up.

I've got four more, guys!

Cost including postage is £54 for the UK, postage for the US was pretty shocking, and brings it, all in, to $92.60 stateside. The only way around this is if you yanks know any servicemen that are serving in the UK at present. And now the photos! I can't for the life of me work out how to upload...

Sorry to hear about the health, Joe- I had an accident four years ago, paralysing my left arm. I've nearly completed three ETW ic engines, and started another steam engine since then! And I still can't squeeze a tube of toothpaste... have you contacted John Chenery about the drawings yet? We...

You've always been "in" Joe. Postage in the UK for this size and weight is set rate, for the US, if weight is a factor, I'll be prepared to rough the interior of your case FOC, to get costs down.

Update. Five cases have now been cast in LM25 aluminium, and heat treated to "TE" (precipitation treated) specification. I am expecting them to be here over the course of the next week. Photographs will follow shortly! Thank you for bearing with me.

I use multi link belts on a Britan lathe, with no trouble at all. When I worked in an auto shop, we used power twist for all replacements. They are a pain to link up, but faster than a headstock strip. On the flip side, my Dad once bought an ML7 which had been using steel studded multilink...
