    Upshur's opposed twin engine

    This is what I thought it meant, but this is very fishy. Using models created from the Upshur drawings, I placed one side of the cam right up to touching the cam follower, but not yet lifting it. Then I placed an overlay of the same cam on the other side of the cam follower, but with the cam...

    Upshur's opposed twin engine

    I have the engine reassembled, and it looks really good. Looks like a John Deere tractor!!! I am puzzled by the notes regarding the valve timing on this engine. The note says "Viewed from the flywheel end of the engine, set the left (1 piston) on top dead center. Loosen the distributor rotor...

    Upshur's opposed twin engine

    This is the green paint glossed out after the oven had cooled down. My main concern was "Would a powder paint from Emerald Coatings flow and gloss out using an oven from Eastwood?" The question has been answered in a most satisfactory manner. Tomorrow I will start putting everything back...

    Upshur's opposed twin engine

    Today I'm figuring out how far powder paint goes. I paid $26 per pound. With my trusty teaspoon I put 10 tea-spoonful's into my powder paint gun bottle. I painted everything multiple coats---the reason being that I can only spray what faces the opening in the spray booth. I turned the aluminum...

    Upshur's opposed twin engine

    So here we are, one cam J.B. Welded to the shaft, other cam with set screws wiped with greasy q-tip inside so it won't stick to the J.B. weld, and the gear wiped inside with grease so it doesn't stick to the J. B. Weld. This seems like such a simple thing, but it took me two hours to do this...

    Upshur's opposed twin engine

    Not a lot got done at the Rupnow house today. We did make one cam with a hub and set screws. I thought a lot about loctiting the cams in place and trying to see if I got it right, but its a major job to do that and then find out I got it wrong. My powder paint is at my front door and I haven't...

    Upshur's opposed twin engine

    It's the FINAL COUNTDOWN!!! I am still confused about the cam positions relative to each other. The cams, gears, and crankcase are as Upshur drew them. (I did add a hub onto one side of the cam gear to lock it to the shaft.) I am running the engine the opposite direction to what Upshur...

    Powder painting a flywheel

    I was into Princess auto yesterday. They sell the powder gun. They do not sell powder.

    Upshur's opposed twin engine

    Hi Roy--I need two of the 90 degree sparkplug boots for the engine I am currently building. The sparkplugs are very small 1/4"-32 plugs (I may have bought them from you) the porcelain measures 0.180" diameter x 0.350" long and the brass part on top of the porcelain measures 0.160" diameter x...

    Powder painting a flywheel

    Yes, I bought the paint powder from Emerald Coatings. Seemed like very nice people to deal with.

    Upshur's opposed twin engine

    And there it is boys and girls!!! a "throttle lever position fixer". There is a coil spring inside that #10 shcs that presses on the head of the throttle screw, keeping it from moving randomly. It is easy to turn it if I want to, but will not turn "by itself". I think that was the last thing I...

    Powder painting a flywheel

    Gordon---Brings back memories.---when I was a kid my old granny lived in Niagara Falls on the Canadian side. One time my mom and I took the train or bus (I can't remember which) down to Niagara for a visit with my Granny. Mom and I and Granny and her boyfriend went across to the American side...

    Three piece mold for sparkplug boots

    Junkyards in Ontario won't let you go in and scrounge anymore. It's been that way for over 25 years. Too many liability claims on their insurance. I used to love going thru junkyards looking for treasures in my hot rod building days, but now you get arrested if they catch you in their yards...

    Powder painting a flywheel

    I have googled powder paint in Canada till my fingers hurt. It's not that easy. 95% of the people advertising Powder Paint in Canada are selling product that originates in United States. We really do only sell pine trees and beaver pelts here. That being said, I went out today with a mission...

    Powder painting a flywheel

    Now that I know that my powder paint system works, I'm down to the nitty gritty of finding a cheap source for powder paint in Ontario, Canada. My Canadian dollar is only worth 73 cents American money. Shipping from America to Canada is about $50. So a half pound of powder paint costs 15$ in...

    Thanks Andrew---That's not the thread I was thinking of, but it shows everything I would have to know to create my own molds.----Brian

    Three piece mold for sparkplug boots

    At some point over the last ten years, on one of my small engine forums, someone had posted plans for a three piece mold to cast your own sparkplug boots from silicone. I'd like to have a closer look at that post now, but I can't find it. Does anybody have a link to that post?---Brian
