Not-a-number Posted February 20, 2020 Author Share Posted February 20, 2020 I have a challenge for you guys. Im look for OEM parts to design around. Starting with Shell bearings and Con Rods. Bearings: Big End. 45mm Diameter. 35mm wide Mains. 60mm diameter 28mm wide Con Rod: 180mm long 45mm bearing (49mm? bearing dependent) 35mm wide Ive found Subi main bearings in the EG33 are 60mm diameter but they dont look wide enough. Old 911 looks close too. Same problem with the big end. Lots of 45mm diameter but not wide enough. The conrod length is super long. Ford Model T or Flathead are 7in which would be fine. But journal diameter is too big. Hoping you guys can help figure out a combo. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post Not-a-number Posted March 8, 2020 Author Popular Post Share Posted March 8, 2020 Managed to buy an original set of pistons and rods on ebay. Look in perfectly good condition to me! Good enough to use to get things going. Theyve been machined out for shell bearings already. 39 Quote Link to comment Share on other sites More sharing options...
Popular Post Not-a-number Posted June 7, 2020 Author Popular Post Share Posted June 7, 2020 Pretty well detailed now. Bearings, seals, cam timing, compression ratio all realistic. Now need to do waterpump, oil pump and drive to supercharger. Dont have drawings for any of that though so need to wait until the Bugatti Trust is open again. 41 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Not-a-number Posted June 7, 2020 Author Popular Post Share Posted June 7, 2020 Since a majority of the engine is modeled and most patterns have been printed I am going to move on to the car (since I dont have a workshop at the moment to do casting). The Ol' man has offered to have a go at making a chassis. I just need to provide him with tooling. The first approach is to try and make it using the original method. Which was to form sheetmetal over a mandrel to produce a C channel type chassis rail. The mandrel is out being manufactured now. 27 Quote Link to comment Share on other sites More sharing options...

Popular Post Not-a-number Posted July 16, 2020 Author Popular Post Share Posted July 16, 2020 So I said I wasnt going to cast things in the US but ive changed my mind Got access to a lot more resource here, more sand options, binders, filters, foundries etc. The sand binder ive got has a lot longer working time and a much longer shelf life. So I should be able to do bigger moulds at home. Out door spray booth. Acetone vape on the patterns. Doesnt work the best on PLA but still blends it together a bit to make it stronger. In theory. First casting will be the cam tree. Using Duratec primer which is super high build and like chalk so easy to sand. 30 Quote Link to comment Share on other sites More sharing options...
Popular Post Not-a-number Posted July 17, 2020 Author Popular Post Share Posted July 17, 2020 For aligning the two halves I have one pattern with holes going right through, other half only about 15mm deep. Clamp the two parts together, align, and run a reamer through into the 2nd part. Then install dowels on the lower half. 30 Quote Link to comment Share on other sites More sharing options...
Popular Post Not-a-number Posted July 20, 2020 Author Popular Post Share Posted July 20, 2020 Did the first mould. Patterns worked well but the sand started going of way quicker than I hoped. Less than 10mins. So theres some voidy areas inside that would be no good for casting. Can still use it for the first mould assembly though. Did a runner system. On the printer now. 22 Quote Link to comment Share on other sites More sharing options...
