Mike You might try and contact Richard Williams who has built one of the PMD engines. Have a look at FloridaAME Home Page and go to Gallery, then Multiple cylinder engines, then about half way down on the right hand column you will see his details. It's a while since I had any contact with him...

Attached is a wiring data sheet from Parvalux to help you. The capacitor you require is 2.5Mfd. I note that your SD21 motor has only a maximum power of 20 Watts (2800rpm version, 1400 rpm version is only 8 watts). I would have thought that this would not have been powerful enough to drive your...

Here's a link to Jan Ridder's compression tester: http://www.ridders.nu/Webpaginas/pagina_compressiemeter/compressiemeter_frameset.htm And here's Brian Rupnow's compression tester: Dave The Emerald Isle

What you describe as a 'Bush' is known as a Gib Strip. It is used to remove play in (this case) the cross slide. The cross slide should have a number of set screws that bear against the gib strip that should be adjusted to remove sideways play, but not so tight as to prevent free movement of...

Norman The file uploaded contains errors. Why I don't know 'cause the original file opens clearly on my laptop. If no one else comes up with the goods, let me have your email address and I'll send it directly to you. Dave The Emerald Isle

Is this the one, Norman? DewhurstSwDiag.jpg Dave The Emerald Isle

Ahh so, JB. Seems like my coil windings are wrong. I got my (bum) info from the owner of the two full size ones shown. I'm not going to do anything to it at least until after Doncaster. Will need to get some more cotton covered wire to do a rewind. Dave The Emerald Isle

Following on from bobcjohn's suggestion, I thought I would test the dynamo by trying to use it as a motor. First I checked the continuity from brush holder to brush holder. Power switch open, open circuit; power switch closed 0 ohms. All good so far. I hooked up a 12v car battery charger and...

Tony Here's Daniela's email address: Daniela Filová <[email protected]> Dave The Emerald Isle

Only a small detour then? Dave The Emerald Isle

JB. I'll try my 'artificial canvas' first and if not successful, I might try you r suggestion. Have you watched this video Bob The lever on the bridge piece is the on/off switch. The other (larger) one adjusts the phase (I think) but to be honest I don't have a clue! Come up and see it at...

Rod I bought the kit off eBay, and as far as I know it was just a feeler for eBay sales because they have not advertised there since. The Polish company can be found here: https://www.danielasteam.com/e-generator-kit If you look at their finished article and mine, you will understand why I...

I've recently completed making an Edison dynamo from about 1890. This has been an on/off project for a couple of years filling in during other jobs. It started off with me buying a set of castings from Poland. At the time, I had no idea what an Edison dynamo was or looked like, but it...

OK, Joe. I think those castings were supplied by Heinz Kornmuller of Classic Motors, Austria. Unfortunately for you, he has retired. It might be worth contacting Engineer's Emporium. They may have taken the design off him. It's not shown on their online catalogue, but that doesn't mean they...

Steve Do you have the tap for the cylinder thread that you would part with? If so, I would like it + 4 engines. Dave The Emerald Isle

Daimler or Karl Benz? If you really mean Daimler, I don't know but if you could mean Karl Benz, then have a look at https://www.ts-modelldampfmaschinen.de/gussteilesaetze-verbrennungsmotoren/verbrennungsmotor-karl-benz.html There was a build article of this engine some time ago. Have a look at...

I know that Richard Williams in OR built one of these. I don't know whether he is still with us, but his email address is [email protected] Maybe worth a shot. Dave The Emerald Isle

Not very helpful to your cause, but you might be interested in this pic. A model poses with the full size (and owner) at Antique Powerland, Brooks OR (just south of Portland) Dave The Emerald Isle

Or consider two piece construction. Use the correct size rod for the stem, put in the groove/cross drill for the retainer, cut off a bit longer than required. The extra length is reduced so the head won't slip up the shaft then silver solder a piece of stock to that. Hold the stem in the...

They were still building vessels with triple expansion engines and low pressure turbines in the 1950s. I know because I sailed on one in my later Merchant Navy career. Dave The Emerald Isle
