After a long period of low activity, driven by some personal issues and competing activities (a couple of bathroom remodels) I’m working on the Locost in earnest again.
I’ve re-built the build table, making it: 1) sturdy enough to support the car with the drivetrain installed, 2) level without the levelling feet, and 3) low enough so that I can more easily work on the chassis and, especially, weld on the top of the chassis. My excuse for burning holes in the top surfaces of the top tubes is now gone.
I had the engine and tranny mocked up in place and was about to fab and tack-weld the engine mounts when I decided that, although I knew the depth of the shallow(er) Race Craft oil sump I planned to use, I wanted to actually see it in place when I finalize the engine location. So, I ordered the sump. I’ve pulled the engine from the chassis, mounted it in the stand and, with the help of my friend Woodinville Dick and his brother, turned it upside down so I can access the sump.
While I was tracking down some rubber lube that I need to use when I mount the sump, I’ve worked out the positioning of the front four suspension A-arm mount brackets. I have them C-clamped in place so that I can tack-weld them. Now I’m working on the lower rear mount brackets, which require mocking up the lower A-arms to get the angle right.
The jury’s out on the upper rear brackets. I have been planning on using removable brackets made from aluminum plate that I can remove and replace so I can play with anti-dive geometry. But something is whispering in my ear, I don’t know whether it’s the little angel on my left shoulder or the little devil on my right, that I should dispense with that complication and simply weld brackets where the book says to.
When I get the suspension mounts at least tack-welded in place I ‘ll be able to fab my A-Arms. Then, with the wishbones in place on one side, I can work out my steering rack position.
But first I’m going to flip the chassis over and weld in the steel panel that goes in the bottom front bay, just behind the radiator, and the sheet steel floor panel in front of the driver to which the brake and clutch pedal assembly will be mounted.
And then I’ve got to determine whether I want to use aluminum or steel sheet for the rest of the cockpit floor panels. And if steel (cheaper but about 20 lbs. heavier), go ahead and cut them to shape and weld them in place.
