    Magneto power?

    In your opinion would a standard 4 cyl. tractor magneto fire 2 plugs per hole? Want to build a v8 but can not find a 8 cyl. magneto.

    Car engine (airplane?)

    Have had this picture for a while and curious if anybody knows what make it is? Looks like the crankcase is end plates with tin riveted to the bottom. Had someone on an other site suggest it is actually an airplane engine.

    How to make a key way?

    How does one cut a key way with out using a broach? the only way I can think of is drill a hole and file it square. Is there a easier way? I have a pile of pulleys and flywheels off various items but none of them are keyed. Thanks, Jon

    Rupnow Klockwork and Jacob ladder projects

    So I decided to try and build these two projects. Being a sheet metal guy I cut them on a laser and will ream the holes on the mill. My question is: The only aluminum drop material I had available to me was some stuff that was scratched up. So I sanded the parts but am curious what...

    Air compressor oil?

    Just picked up a 5hp 22 gallon China made air compressor. The guy got rid of it because it took forever to fill up. In fact the thing vibrated most of the fittings loose and that is why it takes so long. Anyways I want to give it an oil change after I pull the head to check the valves. What oil...

    Free parts idea

    Was stealing an electric motor and foot control off of a sewing machine I got for free for my tiny drill press and decided to turn it over to see all the parts. Wow was I amazed - crankshafts and connecting rods everywhere. Not sure what all the bushings are made of yet but the must be good...

    Have been looking at this engine lately. Cam looks like it should have a narrower lift on it. What is your opinion?

    Ford x-8 engine

    Has anybody ever built a model of a Ford x-8 engine? Saw a picture of one this morning and it looks unique. I would probably make the cylinder, head and valve cages as separate pieces but that is just me. http://www.mtfca.com/discus/messages/118802/179880.html?1293791886

    How does this run?

    Looks cool but how can it run? Doesn't it have pressure at both sides of the piston. I do not see a valve box. https://minneapolis.craigslist.org/hnp/atq/5424583187.html

    Weekend project idea

    Saw this on a surplus website for sale. Can not believe they would charge $27 for it. Might be cool to have it on the table at the next engine show. Next challenge would be how small could you make it?

    Piston trip igniters

    Has anybody built a model engine with piston trip igniter? Was looking at an old Patent drawing and the engine had this on it. I understand the concept of less moving parts but it puts ignition after TDC. Can't believe the engine would run very well.
