Where can I get a card with the proper drill sizes for metric taps and sizes to turn to for metric dies? I have broken several taps using the guesstimation method. Phelonius

What would be a good design of reversing gear for a slow turning long stroke two cylinder double acting engine? Phelonius

Thanks for all the answers. The only one I can disregard is the one about siphoning water from the body of water the boat is in. salt water in the bay is not a good boiler water. phelonius

It would seem to me that with two cylinders and crank throws offset at 90 degrees, if it is a double acting engine, rpm could easily be slowed to 30 RPM or less. Considering that every 90 degrees of crank rotation begins another power pulse, this should be ideal for a slow turning engine. In...

What works better on a flame sniffer, short stroke, or long stroke engine? Slide valve or reed valve? Phelonius

How does one figure how big a boiler to build for a given engine? I would be looking at between 60 and 100 psi, and wondering how to figure one that would generate enough volume of steam to do the job without getting too big to be practical. For instance, a small home made stem engine in a...

The only flame licker I have seen used a reed valve. The one shown here seems to use a slide valve. Good work. Pheloniousp

The trick to getting an oscillator to run slow is to have a heavy flywheel or multicylinders. This one not only can run slow but starts without manual initiation and even reverses by the turn of a valve. No castings though. It is made from brass square stock, and a bronze crankshaft...

I guess a hot air balloon would not have fit in the garage. Phelonius

My next one will have an overhead set of rotary valves. I am ready to build but cannot find any tiny sprockets and chain to turn the valves. Phelonius

I intend using it to make a crankshaft for a 4 cylinder steam-compressed air engine. Any comments about it? Bore 5/8" stroke 3/4" What about rings? Phelonius

I would really like to send videos but do not yet have that skill. I am using a Mac Book laptop. Any help would be welcome. The controller is a 3/4 square brass bar with 3 holes bored lengthwise. One is for the inlet of pressure and one for the exhaust. The third hole has a 1/4" rod with a...

I once did this to run a briggs and stratton engine. I made a needle valve drip gasoline onto a piece of aircleaner foam at the intake. T'werks good! Can it get any simpler? Phelonius

Plans? I don't use no stinking plans! I just cut away everything that does not look like an engine. Phelonius

I was wondering why my frisbe seemed to be getting larger, then it hit me! Phelonius

I am retarded chief bos'ns mate USCG. (That's Uncle Sams' confused group and our motto was simple apparatus or something that sounded like that.) I have been a soldier,Steel mill laborer, ran a liquid oxagen plant, Been a cat skinner, logger, the aforementioned chief bos'ns mate, commercial...

This one I call the wiggler. It is a 4 cylinder oscillator. The first photo shows to the right, the control valve that does on, off, fast, slow, forward and reverse functions. the second photo shows details of the main bearings. The number 2 and number 4 frame members also serve as...

I recently built one of those using a titanium poppet valve made from a piece of aircraft scrap. It was not dependable. My problem was that the valve seat was 360 brass and as the engine ran, the titanium was peening the seat causing it to get out of adjustment. As the seat peened the valve...

I am always needing six inch rules. Mine tend to evaporate just before I need them. Phelonius

Someone should market software that could enable ordinary users to do such a trace. It would do to scammers what caller ID did to obscene phone calls. Phelonius
