landman Posted November 18, 2019 Posted November 18, 2019 Now that I have most of what I need, I'll try to scratch up one of these using a 442 block, some 3D printed carbs as a base. Here's the preliminary fact gathering thread. http://www.modelcarsmag.com/forums/topic/138992-oldsmobile-ow43/
landman Posted November 19, 2019 Author Posted November 19, 2019 Started tonight. Used a 442 block with a 3D printed weber manifold. Used plain rectangular srip for the heads ars they will hardly be visible once the stuff is added. Added coolant outlets and inlrets. I will use three injector stacks for the three air breathers. will fabricate the caps.
landman Posted November 19, 2019 Author Posted November 19, 2019 Made the cam covers using square rods and half round. The marks are the location of the bolts. They did not look right so I redid them with narrow ribbing to represent the ribs on the real thing.
landman Posted November 19, 2019 Author Posted November 19, 2019 Made some caps for the breathers. Had to move my tubes further apart to clear them.
landman Posted November 20, 2019 Author Posted November 20, 2019 (edited) With the outboard cam covers held in place by tape, I could obtain an overall width measurement . I was able to find a good picture of the gear train of the OW-43 which will serve as a template for all those covers. I printed three slightly different ones and I think the one in the photo fits best. I wonder whether there's a cover like that at the back. Edited November 20, 2019 by landman Typo, as usual.
landman Posted November 21, 2019 Author Posted November 21, 2019 Reshaped the heads to give a wider angle between the cam covers to match the image. Bit by bit we are getting there.
landman Posted November 21, 2019 Author Posted November 21, 2019 (edited) Cut the pattern out of a sheet of .040 then glued it to another one to give a proper thickness. Punched some "covers" for the ends of the cams. Edited November 22, 2019 by landman
landman Posted November 23, 2019 Author Posted November 23, 2019 The front cover is taking shape. I had to quit because I was getting cross-eyed.

landman Posted November 23, 2019 Author Posted November 23, 2019 (edited) Pecked away at it a bit again this morning. Edited November 23, 2019 by landman
landman Posted November 24, 2019 Author Posted November 24, 2019 Trial fitting the components to see if it will look the part.
landman Posted November 24, 2019 Author Posted November 24, 2019 Pretty well complete. Still need to do some plumbing and wiring as well as deciding what to do with the exhaust.
landman Posted November 25, 2019 Author Posted November 25, 2019 Project complete. This is supposed to be a representation of Oldsmobile's OW-43.
