    Jim builds his second v-8

    Doubt I have enough power and speed reduction for a wheel that large. At work I had a tool and cutter grinder that used 7 inch wheels. My spindle is 3/8 inch dia. I made a bushing 3/8 to 7/8 for the cut-off wheels. I think 4 inch wheels max it out. 0.005 is a heavy cut maybe too heavy but the...

    For a rough pass I infeed about 0.005 pretty darn slow, maybe 10 seconds. I hand feed really slow too so it's time consuming. I sneak in a thou or two for the finish pass. I then make a pass or two with no infeed to let it "spark out."

    Got all bearing surfaces resurfaced. I have a Dumore toolpost grinder. I have a hard time finding wheels large enough to do a crank so I've resigned to using cut-off wheels designed for angle grinders. The one I used on this job is an A46 grit 1/16 inch wide. I dress it of course with a diamond...

    Fix'n up the old crank. Gonna have to make some non-standard bushings.

    Bronze bushings and shells on the mains.

    Good idea. Rods were from plate I picked up at the scrap yard. I don't really know the analyses. I outta pick up some better material for the second run.

    Aluminum. Think maybe the sleeves, pistons and rings are ok. I got an earlier v8 I've been running for a long while, 5 gallons of fuel or more. It's built the same way and running nicely. Always ran it though on premix. On this one I depended on the splash system. Gotta rethink my that...

    Jim builds his second v-8

    Bad day in Jim's shop. I'm not sure if it's totaled but close. It got running really poorly so I ran a compression test and found the front 2 cylinders to have about 40psi while the back 2 came up to 75psi or so. Middle cylinders all tested somewhere in the middle. Curious to find the cause of...

    Interested in hardening a hall effect sensor, check out the picture. It works.

    Regarding the thermostat question: I've got none. I've got a thermometer though. Its an old school glass Celsius job. The bulb will just slip down the fill hole in the radiator. Regarding the ignition question: The wires are not joined, I used a piece of silicon zip cord from the electronics...

    You can see by the picture I've temporarily added the radiator. I used a small fan too to move air through the radiator. I ran it for 15 minutes with the temperature stable about 85 degrees C. I thought the idle was a little fast then so I slowed it down some and not long after started making...

    Not so Art. My heads have a 5/32 water passage running lengthwise full length. Water enters the heads from the back of the block then exits through the intake manifold to the radiator.

    My hope was to be able to idle it forever. Not happening yet. Some builders at the shows have huge radiators, way to big for scale (heater cores maybe). Your Demon radiator looks really appropriately sized for scale. I thought mine was somewhat large but not too bad but I'm leaning towards...

    Thanks guys, Steve, you have any overheating issues with the Demon?

    Jim builds his second v-8

    Well, here it is again. I was running it on premix but now dippers have been added to the rod caps, oil has been added to the crankcase, the headers have been bolted on, fuel is straight camp fuel. I've run about 10 tanks through it, each taking about 6 minutes. It doesn't smoke and I haven't...

    Jim builds his second v-8

    Yeah, needs a lot of clean-up. Had it looking somewhat nice for the names show but hadn't yet run it enough. Got no splashers on the rod caps yet so I've been running it on pre-mix. Maybe I'll do that tomorrow. Won't rev well yet either. Got some trouble in the distributor cap too cuz a cylinder...

    http://www.youtube.com/watch?v=mnWk2udR96k I've been away from the Forum for a while. I have made some progress. Here's a video of the first run. It needs some tweaking but it's showing some possibilities.

    Crankshaft went kaboom, please help

    What a beautiful engine. Its a sweetie. Silver solder will work. You need a couple of thousands clearance for the solder. Flux the parts well. Flux will not flow into the joint too well so you'll need to coat them both well before assembly. I'd ream the hole for an exact fit then over bore part...
