  1. Hello, Today, at last, I completed the drawing of the simplest head gasket of the Cleveland engine. Next in line is the more complex head gasket. The Cleveland has two head gaskets, one for the inlet and exhaust "chamber", and one for the head to the cylinder. I am sorry for the quality of the picture, during conversion from DWG to PDF to JPG, it got blurry. I need to investigate to improve that process. To day I started early, 07:00 hr and managed to get the Ford model A engine running, but oh boy is that engine tight. So after running the engine for 30 minutes at l
  2. Hello Terry, Thank you very much for offering your expertise! I am impressed by the quality of the drawing and molds, they look wonderful. To be honest, one of the many problems with the Cleveland, are the brake drums. This type of drums, I only saw these fitted on a 1903 Mitchell. They did not came with the Cleveland when I bought it. I postponed the manufacturing of them, hoped I would find them some day. But after looking for them during 20 odd years I gave up. So I could make molds of wood (the proven but old fashioned way), instead I am thinking about drawing them in 3D. But, as
  3. Hello Mike, At my former job, my department used AutoCad (2D) for years. A few engineers where quite good with it. But some years ago, we needed to draw our designs more and more 3D. So we changed to Fusion 360.... well, that took quite a while, courses and effort, before they mastered it. But, I must say, the results where marvelous. A few years ago I gave it a try, and very soon lost the battle 😒. As I need drawings for the head gaskets and drawings for bell-cranks (to have them water or plasma cut), I think 2D is OK for the near future. Later (when mastering 3D) I hope to make 3D mol
  4. Hello, I got a bit distracted by finishing the rebuild of the Ford model A engine. Took a lot more time and effort than I previously anticipated. For example, the carburetor: I am fond of Tillotson carburetors for the Ford, always driven them with the Tillotson model X and have good experiences with them. Sold my last one to a friend (should not have done that...) As they are a bit rare in the Netherlands, I ordered a "rebuild" one on Ebay. Big mistake, the carburetor looked good (at first glance) but when put on the engine, it leaked petrol like a sieve. Well, disassembled the carb, no gasket
  5. Hello, Today I spend a lot of time, taking measurements of the position of the con rod in relation to the sump. Well, the idea of yesterday of making some kind of oil catcher will not work. I was mistaken by the position of the drip oiler on the engine, it drips on the wrong side of the con rod. Redirecting the oil, by some kind tubing seems not possible, there is not enough room into the crankcase for it. I turned the con rod up side down, oil hole to the bottom of the engine. Well, the distance between the oil hole and the sump is just 1 3/8". The con rod also turns into the right
  6. Hello Mark, Looks nice and shiny, well the inclusion, I would be "creative" with the oil grooves😀, I would use it as is. Keeping in mind that the bearing is used for an accessory shaft. I guess that the load is not an impact load as with a crankshaft or con rods. If used for a crankshaft or con rods, I would re-pour it, but not for this application. Regards, Harm
  7. Hello Terry, I think that is a real possibility, as there is an oiler just above the rotational returning point of the con rod. So if I keep the hole up (as Cadillac did) and I make some kind of "oil catcher "and screw that into the hole, oil supply is guaranteed. Well, tomorrow I will take some measurements, to proof that this will work as described. One of the pictures I got from Roger Weiss shows an Oiler on top of the engine. Regards, Harm
  8. Hello Al, Thanks, but I really have no idea. Maybe they screwed in some kind of oil scoop? I still have to measure the clearance between the lowest point of the crankshaft and the sump. Regards, Harm
  9. Today, after searching the web, I found a nice detailed picture of a Cadillac con rod. It seems to answer my question about the threaded hole in the Cleveland con rod. To me it looked like an oil hole. See picture below, red arrow point to the oil hole. Gentleman, do I assume this right, that it is an oil hole? Picture copied from a 1903 "Instruction Book for the Cadillac Automobile" Regarding the counterweights, I could not find another crankshaft from that period, with this bolted on counter weights. Regards, Harm
  10. Hello sir, That is a nice set of molds you have made. Keeping the mold, the shell and the Babbitt at temperature is indeed very important. I use a fairly large cast iron ladle (drawback: its heavy), this keeps the temperature of the Babbitt long enough stable for pouring. When I did my first pour (longer ago than I want to remember 😁), it really looked terrible, but after a while I got the hang of it. I just kept on trying. The car still runs on that Babbitt bearings. Good luck with your second pour. Regards, Harm
  11. This morning I took a picture of the hole in the con rod diameter about 5/16", it has a very fine thread in it. Did not figure out yet what kind of thread it is. As you can see, the connecting rod sides are machined, but left with a really very rough finish. Threaded hole in connecting rod. (Somehow I have the idea that the hole was later machined there.) Here are all the counterweights parts. Counterweights weighing 4.33 Lbs each. Assembled counterweights with the crankshaft. Side view of the assembled counterweigh
  12. Hello Ed, Thanks for your advise. No the engine does not have a scupper, looking at the con rod cap it did not have one originally. The only strange thing I can see, the con rod has a threaded hole (about 3/8") to the bearing like and oil hole, but why threaded? Did some oil catcher of some sort was screwed in that hole? Could that be some kind of scupper, mmm interesting. Time to find out how deep the con rod goes into the sump. Maybe I can design something acting like a scupper. I will take detail pictures tomorrow. Regards, Harm
  13. Hello Mike, Yes, I was aware that that you had the same weather, saw it on the weather radar pictures. After the weekend thaw will set in here, and temperatures will rise to 50F, but they also predicted a lot of rain. But first we will have some bitter cold nights. Mike, thank you for the Douglas Motorcycle link. The way they assembled the con rods, and the con rod bearings at the crankshaft is very ingenious, really very clever. I guess these motor bikes were expensive in their time? The bearings for these engines are split roller bearings. I had a very enjoyable afternoon a
  14. Hi Al, No snow at all. Saturday morning the 6th the temperature was about 40F and it rained a bit. Late in the afternoon it became windy and colder. At night the temperature dropped fast, and "windy" became a storm and it started to snow. And it stayed till Tuesday morning. At this very moment its 18F outside... Regards, Harm
  15. Hello, The last week of January I spend at completing the Ford model A engine. I rebuild the distributor, oil pump, water pump and starter motor, also new valves etc. Went well, until I put in the adjustable valve lifters. They are impossible to adjust easily, the problem is that the square on the lifter body falls below the lifter guide (with the valve in closed position), so it is impossible to put a spanner on it. Luckily, a lot has been written about it, so I do "What the Romans did" and follow the advises given . Last Friday and Saturday I cleaned the Babbitt bearing of
