I've searched all over for these plans. Does anyone have a link to them so I can download a copy of them. Or do I have to buy them from Brian. I'm looking for a set of plans to finish off the winter. I just finished a Farm Boy from plans I purchased from Howell's company. Thank you, Merry...

I'm having trouble getting the engine to run. It seems as though I'm losing compression back through the intake valve. I have tried seating it with course grinding compound and also real fine compound. Neither has worked. What else could be defeating my efforts. I have noticed if I run the...

I'd like to know the thickness of the Delrin bracket? I'm guessing it's about .250 . This is the one for "not using spark saver". Also the coil I got from Howell only has one terminal on it besides the spark plug wire. The TIM 6 has a connector for a plus and a minus. How do I connect it to...

I had the misfortune of breaking a 2/56 tap in cast iron flywheel on my Farmboy engine. Low and behold I tried an old trick I learned in my old place of employment. Get hold of an American made official #1 dart. I picked at the little tap and to my surprise I was able to back it out. I don't...

I'm looking for the part and place where the 2 #44 drilled and countersunk holes go on what mating part of the Governor Weight Fulcrum Hub? For the life of me I can't find where the tapped 2/56 holes are. Could it be on the Governor side Flywheel? It's not shown on either flywheel as a .412...

I am making the valves for a Farmboy engine. I would like to know if I should machine the valve major diameter .375 out on the end of the shaft and have the small .125 dia. near the chuck to part it off when finished. I'm leaning to having the .125 turned on the end of the shaft towards the...

I'm looking for the article written in one of the Home Shop Machinist magazines or on this forum or one of the other forums. I read the article and didn't print it out , now I can't locate it. Does anyone know where it is so I can copy it. I need to put a thrust bearing in it and I don't know...

How do I go about cutting the cam for the Farmboy engine? The article in home shop magazine is way above my understanding. I was thinking of offsetting the cam in my 4 jaw chuck but don't understand how far off center it needs to be. Anyone cut any cams for one of these Farmboys lately?

I bought a Grizzly 4" rotary table with index plates yesterday. I doesn't come with a manual or instructions on how to set up the index plates or use the table. My mistake for not asking. But I need a chart or something as such to set up the index plates for cutting different divisions on it...

Just finished my first project since I retired 2 years ago. It's a Jerry Howell plan for a Super Stirling Cycle Fan. I didn't know if I had the equipment to do it but I did. It was fun building it and more thrilling when it actually ran yesterday. I ran into some glitches ,but I over came them...

I want to know if I can put another upper insulating gasket on top of the 2 already there to get clearance for my Displacer body to keep it from hitting the bottom of the hot cap. I need from what I measure another .050 and the gasket material is .062 approx. I checked all my parts dimmensions...

I'm building the Jerry Howell Super Stirling engine. Can I substitute brass/bronze for the Stainless Steel on the 2 rotors of the main crankshaft. I believe they are 1.250 in dia. I just don't have any access to it and besides it's a real bear to machine. Thanks Boot
