An M.G. Locost Build

We did it! We got the Locost on all four wheels. This has been one of the longest phases of the project, taking a basic Locost frame and turning it into something that we can roll up and down the street. Of course we haven't actually done that yet, rolled it up and down the street, but we haven't ruled it out yet, either.

According to our highly-detailed yet wildly inaccurate build plan we are almost exactly 50% complete, but that's something we hope to disprove by whipping through the final stages of the build with a can-do attitude and an experienced hand, assuming we can find anything like that around here.

Obviously a big moment when we finished up the brakes and bolted on the rear wheels, especially since up until now we'd only assumed we had enough clearance for the tires. Our original drawings showed the rear tires clearing the outboard trailing link nuts by only 1/4", but we figured what the heck, the drawings were probably off anyway, and worst case scenario we can get bigger wheel spacers or smaller tires. Now, with the car on the ground, our actual, measured clearance after torquing the rear wheels: 1/4".

Just like we drew it up

With the chassis together we were able to take measurements of things that we only guessed at before, like the wheelbase. Ours measures 90-3/4", which seems shorter than I remember from our PowerPoint drawings, but it is in fact adjustable, should that be even remotely necessary, by lengthening the rear trailing links. Our front track measures 52-1/4", a half inch wider than our rear track of 51-3/4", which measures exactly that and pretty much had to, since we used a stock 49-1/4" MGB axle and a pair of 1-1/4" wheel spacers.

Our driveshaft definitely needs to be shortened. The distance between the rear transmission flange and the front differential flange is 21", give or take 1/16", so we're thinking the driveshaft should be 20-3/4" fully compressed. The U-joints and extension take up about 8" of that, so the actual driveshaft tube will barely be a foot long. This is going to be a job for a machine shop, not because we couldn't do the welding ourselves, because we totally could, but because we don't have the equipment to properly balance it.

  Who needs a hood anyway?

Ground clearance with our fake shocks is six inches front and rear. We think the front end will be lower with actual shocks, since the lower A-arms aren't quite parallel with the ground right now, but it won't drop below 5" in any case. What's more certain is the hood bulge, which is going to be every bit of 2" high at the front of the engine, based on where the nose meets the valve cover. Of course the carburetors sit just as high, but we'll worry about clearance for those later on. Or never.

The next highest point on the engine is the thermostat housing, which might need a slight bulge of its own. The upper radiator hose, which attaches to the housing, may just clear the underside of the nose. If we'd mounted the engine even a little bit higher, we'd have a problem, but we're okay where it is now. If the hose rubs against the fiberglass nose, no big deal, since we're mainly only concerned with clearance issues if they make noise.

A little disappointing that it doesn't run yet

Everything else is looking pretty good, and so far we haven't come across any other clearance issues. Very promising. With the chassis more or less complete we now have phase four of this project in the books. We hope you like the pictures so far. For those of you wondering, and even for those who aren't, the entire project has a total of seven phases, and the next one is our favorite: Getting the car running. We really like being able to sit in the car, but we really don't like not being able to turn the key.

That's so awesome! Sitting in a car you entirely made from a pile of steel tubing, and some parts from an old little car. I can only imagine the feeling of accomplishment and pride as this last picture was taken. Not to be forgotten is your great journalism and way of conveying your thoughts to us.
