    Upshur's opposed twin engine

    Yes Jason, in a perfect world you are probably right. My world isn't perfect all the time.---Brian

    Upshur's opposed twin engine

    The throttle lever on this engine is a bit funky. The only thing holding it in place rotationally is God and the plastic gas line. I have designed a "throttle keeper" (the yellow part) which clamps onto the near side gas line with a #5 shcs.. This throttle keeper holds a #10 shcs which is...

    Upshur's opposed twin engine

    And here a (at an almost microscopic scale), are the rotor shown in place and the distributor cap setting on top of a pill bottle. That center bolt on the distributor cap was supposed to be a #2-56, but I stripped the threads, so went up to a #4-40 stud instead. The distributor cap is 1.060"...

    I do like the look of those a lot better. Maybe I will give Roy a call and see if he still has any. Somewhere on one of the forums I attend, someone posted plans for a three piece mold to make your own very similar sparkplug boots from silicone. Does anybody have a link to that thread?---Brian

    I will check out some of the electrical supply places around Barrie. That connector doesn't look like it would be difficult to source, but I'll find out.---Brian

    Upshur's opposed twin engine

    And this is all the work I'm going to do today. The brass has been sized to fit into the groove in the top of the rotor and glued in there with J.B. Weld. Tomorrow I will see whether or not the J.B. Weld is going to stick to the rotor.

    Yes, that is what I'm looking for. I think they may have them at Canadian Tire. I will have a look tomorrow.---Thanx

    Upshur's opposed twin engine

    Here is a bit of an odd question. I am using a 1/4"-32 sparkplug in this engine. The end which the wire attaches to is 0.160" diameter x +/-0.075" long. Does anyone know of a sparkplug boot that fits over this size of sparkplug or is it a flat/split wire terminator that snaps over the reduced...

    Upshur's opposed twin engine

    After a two month break away from this engine, it is now time to buckle down and try to make it run. Really, the only thing left to sort out is the valve timing, and finishing off the distributor and rotor. The mystery nylon that I made the cap and rotor from is exactly that---a mystery. I...

    Powder painting a flywheel

    So there we are boys and girls--my very first powder coated items. They turned out beautiful!! The powder coating is not difficult to apply at all. The hard part is coming up with the $700 or so that it takes to buy the powder paint gun kit and the bake oven (in Canada). You can save $230 for...

    Powder painting a flywheel

    As far as calibration on the thermometer is concerned.--I put the thermometer in my wife's kitchen oven and set the oven for 400 degrees. After 20 minute the thermometer read 400 degrees. That is all the calibration the thermometer needs.

    Powder painting a flywheel

    WOWZA!!!---It doesn't get much better than this. This is the flywheel that I just powder painted and baked in the Eastwood oven. This is everything I had hoped for. In about fifteen minutes I am going to powder paint the other flywheel. Sparky--I have a good friend who is an electrician---I...

    Powder painting a flywheel

    I just ran out to see what's happening in my Eastwood oven, and the powder paint is flowing out beautifully. In fifteen more minutes I will take it out of the oven and snap a picture of it. I will do the second flywheel later today, and if it turns out as nicely, I will call Eastwood and cancel...

    Powder painting a flywheel

    Today I absolutely HAD to try this out. Eastwood tells me they are sending me a new oven, no charge, but not until the end of November. The Eastwood oven I currently have only goes to 355 degrees maximum, not 400 degrees which the literature says is required. I have talked to numerous sources...

    Powder painting a flywheel

    If my voltage supply was low enough to present problems with my oven, then all the other electrical things in my house would be acting weird---and they are not. The oven I bought a few years ago is lined with fire brick and is much to small to heat treat things in.

    Powder painting a flywheel

    I spoke to Eastwood again today regarding the new oven they are sending me. Found out that the ovens are back ordered and won't be in until the end of November.---POOP!! This doesn't really hurt me too much. I guess I will go back to working on my model engines. I will keep you posted about how...

    Powder painting a flywheel

    It's been an exciting, rewarding, and expensive August and September. For less than $800 I have a dedicated powder paint booth with fan, a powder paint kit including gun, s.s. wire to hang parts, a roll of heat proof masking tape, a selection of powder paints, and a selection of heat resistant...

    Powder painting a flywheel

    Okay---New News!! I have spoken with the rep at Eastwood, tried a couple of things he suggested, and oven still won't go above 355 degrees. They are sending me a new oven, no charge. I asked them to PLEASE plug it in and check that it goes to 400 degrees before they send it.---They were very...

    Powder painting a flywheel

    Maybe rock and roll will be postponed for a bit. I can not get the bake oven from Eastwood up to 400 degrees F. I have followed all the correct procedures and everything is set up to what Eastwood specifies in terms of dedicated circuit, no extension cord, and settings on the oven dials. The...

    Powder painting a flywheel

    And here we are---ready to ROCK AND ROLL!!!! The flywheel has been wiped down with acetone. I added a 1/8" aluminum plate to the bottom of the fixturing just to keep things from flopping around when I move from the paint booth over to the bake oven. The flywheel is not fastened to the shaft--it...
