  1. V-8, V-12 and V-16 engines from Cadillac built at the same frame time are very similar. When I'm looking here at the Lincoln engine, I'm wondering if the same engineers designed the Lincoln and Cadillac engines!
  2. A tiny spring...No rocket science, isn't it? Well, if only I would have fingers' size in relation to the spring! It went twice in the air, found it on the floor both times, a luck! Now, the hand brake lever is functional; I hope that after the plating (only the tiny rod is painted), there will be enough play at the handle and pawl to let the spring doing his job, because his strength is rather limited! I will go now to the other side of the transmission: one cover must be done plus the brake and clutch support which is bolted to the transmission. I think I will need again the help from Ale
  3. Only a small detail is missing; otherwise, the hand brake lever is complete. What's missing? A tiny spring which is located between the movable handle and the fixed one. With the spring, the pawl is pushed down, securing the lever when the hand brake is activated. As you can see, the rod is screwed into the trunnion. I wanted to skip that complication, but I quickly realized that this is need, otherwise the rod cannot be inserted into the guide near the pivoting point.
  4. Thanks Randy! Do you know why most of the modelers don't go that far into the details? They don't have the time; what they are beginning should be ready the next day!
  5. It seems that my expectation about a workable hand brake will come to reality. I did the pawl, out of steel as brass may be too weak. Indeed, I made two pieces. As the first one did not please me, the second one was refined, somewhat shorter and the geometry modified a bit. When the lower part of the hand brake lever will go to the left, the pawl is preventing the movement. On the contrary, the pawl allow the movement and the hand brake can be set without using the handle at the top of the lever, which will be done shortly. The hole on the lever just above the pawl is for the rod actuating t
  6. Thanks for the comments! Another small item added: the ratchet for the hand brake. At first glance, it's an easy part, but not for a model. First, I wanted to have it wide enough for strength, but the starter motor said no: I'm too close. The plan B was to have a thinner plate to satisfy the starter motor and a wider element with the teeth. But, how to do the teeth? On my basic machine, I cannot mill a curved segment and be sure that the distance between teeth is the same. As I intended to do the part in two pieces, the solution was easy: to mill the teeth on a straight piece with
  7. The hand brake lever is looking a lot like a sculpture from the Swiss Giacometti, but has no value compared to his "marvels"! For the moment, there is just the profile from that lever and the lower part is far from finished: there will be a fork for the pawl. I will first doing the upper part and then the lower one. On the real car, this lever is about 20" tall from the axle to the end...Imagine that is a car from today!
  8. Sometimes, I'm wandering from one element to another one, without relation between both. After the frame was ready, I was faced with the same question: and now? There are still hundreds of parts to be made, the choice is large enough! This time, I decided to finish one element: the transmission. The closing cover was just not yet done, not a big deal. This small part let me do many errors by not paying attention at what I was doing. I first did the flat part from the cover with a thick brass plate. Easy. Then I did the holes for the screws. As the location for the holes is done just with
  9. Pat, you certainly know that I cannot build a scale model without functioning elements! Sure, the steering box will be added as well as the column and wheel. The hand brake will come maybe soon as I'm doing right now the cover for the transmission. You will ask: what is the relation? Well, the shaft for the hand brake is part of that cover. Clutch and brake pedal will be added; the goal is that the brakes at each wheel will be functioning. We'll see once if I'm too ambitious or not...
  10. Years ago, I had thousands owner's manuals, catalogs and shop manuals for GM vehicles. For 3 or 4 years, I sold the whole inventory to a man in Germany. Yesterday, by searching something else, I found some Chevrolet leaflets. Why did they not go to Germany, I don't know. Here is what I have for sale: Folder 1960 Chevrolet Corvette 1960, 8 pages, 12.8" x 5", $ 15.00 or best offer Leaflet 1960 Chevrolet, all models, 8 pages, 10.6" x 6.9", $ 10.00 obo Leaflet 1964 Chevrolet Chevelle IN FRENCH, 14 pages, 11.4" x 8.7", $ 10.00 (Only one available) Leaflet
  11. Pat, something is missing on my parts: the thing to put the grease. I still don't know if I will ad them; there are maybe about 60! Anyway, thanks for your comments. Finally, the frame is ready: I fabricated the supports for the transmission and silver soldered them to the second cross member. With that done, it was rather easy to put the cross member into the frame (thanks its elasticity, I had not too much trouble to insert and remove it several times times) and soft soldering it. The rivets are not yet in place as you can see. The rubber bushings at the rear transmission was a
  12. With a lot of guessing and silver soldering, the brackets for the rocker shafts are done. I also added the thread to attach the exhaust support. My first guessing was not right, the first shaft was too near from the cross member (or the shape from the cross member is not quite correct). I had to tilt up the special tool and add a spacer on the bracket's flange. With that, the second shaft was much too high (it would have been above the frame); I had to modify the tool to have it at the "right" place. Then the job was cut, adjust, solder, let cool to handle it, verify that both shafts are st
  13. Thanks Auburncoupe for the good part which arrived recently!
  14. The parts arrived to the customer, in good condition. Thanks Auburncoupe!
