With a stack of wood shims under the oil pan, the bell housing was removed so I could work on the rear of the engine. The flywheel was stuck fast on the crankshaft and without provisions made for jackscrews to remove it, a shop-made puller was needed to separate them. The reason for its enormous...

Nice work on the gaskets. I do something similar on my Tormach. For a work table I used a piece of two inch thick formica covered table top. A heavy metal bracket bolted to its bottom allows me to mount the table in my vise and most the top is surprisingly normal to the spindle axis. For a...

A bowl gasket and heat insulator mounting block were machined while waiting for the delivery of an 8-80 tap and die set. Model engine carb adjustments are traditionally sensitive especially when using gasoline. Every cold start seems to require some re-tweaking regardless of how well the engine...

I bought the cabinet back in the mid-90's from, I think, Eastwood. I remember purchasing a spare nozzle at the same time, as I thought they might wear out quickly, but I'm still running with the original one. The glass bead media I use was purchased from the local Harbor Freight at the same...

I'm using Sprutcam which imports native SolidWorks files directly. The version I'm using (SC-7) is some 22 years old now. At the time it was only few hundred dollars and was the most affordable continuous 4 axis CAM programs available. I've used it for all my camshafts. Many have likely never...

Actually, none. I'm willing to spend the time to let the machine do it. I've learned it's best to keep my hands away from the parts if I can. - Terry

The carburetor and its 'fixins' should be the final parts for this build. George designed a carburetor specifically for this engine, and I wanted to stick to its internals as closely as possible. The recirculating fuel loop I want to use though will require the addition of a fuel bowl. My fuel...

One or two things to check for with lathe CNC: 1) make sure that both you and your software(s) are using the same definition for depth-of-cut, i.e. radius or diameter, and 2) make sure that both you (during zeroing) and your software(s) are using the same definition for tip of tool. I ran into...

Peter, Thanks for the info. I was familiar with the clamp 'gizmo' but even a miniaturized shop-made version of it wouldn't have fit in the space I had to work with around my water pump inlet. It does make a professional looking clamp though. The spring clamps in the photo you provided are the...

The hardware needed to mount and connect the radiator to the engine was completed next. Threaded inlet and outlet hose barbs were turned from 303 stainless and Loctite'd into the tanks. Aluminum-to-stainless bonds are challenging for Locite, and so the parts were pre-coated with the...

I just checked out the PICTIM (hadn't before heard of it before your comment) on their website. There's no automatic timing advance, but they claim it's a possible future addition. I think the only programmable feature is a jumper to convert between a single spark firing mode and a multi-spark...

You might think about LH threading the rod on one and RH threading it on the other. That way you can adjust its length and therefore the initial advance setting insitu. - Terry

I'd forgotten that Jerry provided for a mechanical linkage between the throttle and distributor to provide mechanical advice. Therefore, I'd set it up as he suggests with 0 deg BTDC and then get the advance from the linkage when running. - Terry

The rotor and the trigger positions are independent and set separately. First, set the trigger position. Rotate the Hall mount and/or the distributor rotation so the Hall device triggers at your desired initial timing setting for cylinder #1 which may be, say, 10 deg BTDC for cylinder #1. Use a...

For a radiator, I decided to reuse the strategy I came up with for the Offy's coolant system. My argument was that I felt the volume taken up by the fins in the core of a scaled radiator might be put to better use holding additional coolant. These fins can take up as much as two thirds of the...

Really nice work and I also appreciate the effort put into documenting it. Something to think about before you get too far into brass gears. There's a lot of stress on the tiny teeth of those gears in that gear tower stack. I machined my gears from Stressproof. Ron Colona in fact had one of his...
