  1. Thank you for sharing your story. Stay on, time is not relevant but health and life is. Love to hear about your project, as mine is getting ito a decisive stage. There is still some work to do on the body design like moving the radiator back over the front axle.... but the project is so much fun and pleasure, so I enjoy and let it be a neverending story.
  2. Hello Marc, doyou have some actual pics? You should have some improvements after 1,5 years Id love to see. karsten
  3. Thank you Terry! Fantastic explanation and work you have done here.
  4. Starting to do maintenence on the F6 engine I discovered that some valve guides are burned. One valve has a 3 mm long fracture on the shaft. Does somebody have information about the valve guide material and if the fracture is to be considered to become a valve failure, breaking appart?
  5. The bigger sprocket is a new part manufactured and hardened on the older ones basis. No weldings as it is a security part that transmits the brake power from the drums installed on the same drive shaft.
  6. I also changed the sprocket size increasing two more teeth as I had chain to compensate the length. The beautiful shifting mechanism runs smooth and is ready to go. I have to reconsider some shifting rod position and the pedals, but this should not be too difficult.
  7. The gearbox was a complete mess. The gears grinded and a pound of metal pieces sedimented. I could tell the day I opened it in El Paso 's yard that there was nothing left there. It happened to be wrong g. As one of the main tasks I started to dismantle the transmission and was truely exited about the engineering behind it. A two floor transmission. The upper half the shifting gears, the lower the differential with separetad lubrication system. Beautifully manufactured and well thought. The differential was about mint. A heavy oil, more grease protected the conical gears from rusting. The bearings top. So I had to focus only on the bearings and grinderd gears. In total 3 that had to be made. In Mexico we may have a lack of high tech skilled machine operators, but we have a surprising good fundus of artisians knowing how to mill a gear with their 80 year old machines. Even the cutter for the gear modul was in a dusty forgotten wood box from the shops grandfathers time. These guys made a terrific job. The parts matched 1:1 immediately and testing was successul. The bearings were brought together from several shops arround the country, as they are also rare and discontinued. So, despite leaking oil through some unaccessible joints, the gearbox has become a proud piece of prewar engineering, designed and build when Titanic was on the drawing board. Same as the engine. The F6 T Head was designed 1910. Up to now I have only one major problem unsolved; The wheels, the metal rim is totally corroded. To make new ones cost over 1000 US a piece. I have to figure out what to do here and maybe someone has an old Seagrave truck and wants to sell the wheels. Anyhow. In a few month I will have this issue on my time frame.. Meanwhile I will prepare to change the engine from the 1929 Seagrave truck to the 1919 Speedster chassis. I am very exited about this step.
  8. Time flies and my chassis will be 100 hundred years old this 2019. There have been some improvements but still a way to go. The gearbox is compleete and installed. The chassis clean an looks like mint. Next step is to install the F6 T head. Have all spares together and look forward for a great time.
  9. Hello Dave, I went to El Paso to pick up the chassis . It is a long and very interesting story, close to an adventure as it had to be passd over to MX . I was very lucky to find this 1919 seagrave pumper, as my later 1929 model has the exact same chassis dimensions wirh drive shaft. Indeed a wonderful project which ends up in passion. I dismanteled everything. Now that I am rebuilding and giving fresh breath to this unique automobile I can imagine the intense job it was manufacturing it at that time. It is easy to be said: 1919, but refering to the technological improvings they were at the very beginning of combustion engines. But fire engines seemed to be far ahead of its period. Be Safe Karsten
  10. Thanks for the advice. Enclosed some other pictures. Cronologically they are mixed up. but should give an idea. End of this year I will assemble the gearbox and chain drive. If there is time left I will extract the F6 Engine from my 1929 Firetruck and installit in this 1919 chassis. Up to now everything works well. Of course gears and sprockets had to be made, change hugest bearings, the brakes completely overhauled and left as they are. I intend to change just the needed parts. A difficult problem are the wood spoke wheels. I am goint to flush them with Abatron Liquid wood, hoping to gain strenght and stability. This also should be end of the year. If I have time left this week and Liquid wood arrives, I may try on the worst wheel. Hopefully this will work. The anti - sag tension basr will be removed as soon as I can calculate the total weight on the beams. I am afraid, even if I took out the 1000 kg water pump made out of solid brass, that the beams may collaps. I love the 2 layer gearbox. State of the art. These engineers did know what theiy were doing 1910...1919. The upper layer is the shifting mechanism, the lower layer the differential. Fantastc solution. Compact but still outstanding big. I wonder how the oil is going to be used, as there is no connection between the layers and it seems to be 2 different oiling systems. Maybe somebody knows about how this works. More pictures soon Thanks for passing by Best regards Karsten
  11. Unfortunately I cannot upload more images.
  12. July 2018 The speedster project goes on. Up to now all parts have been brushed and cleaned. At the moment I am trying to recover the wood spoke wheels. The rims are in an awful shape, but can be made. This wll,give me the chance to mount 700x24 tires. Enclosed some pictures of the job done somfar.
  13. Hello Chase! I am sorry to hear about your delay having your project done.This kind of things happen once a while so you should not loose hope.. But, If you intend to sell parts of the seagrave engine, I would be proud to integrate them into my project.
  14. Al, The ALF was the one I was looking for 2012...2014. Unfortunately without luck. Then I bought the Seagrave. ALF / Simplex are not so massive in design as Seagrave and in my oppinion are just beautiful. The Seagrave F6 Engine is an extrem workhorse and expects an even massive and good finish all arround . As soon as we have the details over I share and hope for comments how to do some things better. At the moment I have to decide if I leave the old patina on chromed parts or to polish them up and chrome again. I think I will leave the patina as it gives the worn out look of a well used classic car. What do you think? I found a museum close to Frankfurt: www.central-garage.de . It has the original Simplex engine drawings hanging in the shop... Hilarious!! Also the Mercedes Benz Museum in Stuttgart and Museum Sinsheim are woth to take a closer look as they have a lot of expossés of our main interest and good for ideas! Best regards karsten
  15. Hello Al, yes, I would like to keep thespoke wheels , as together with the F6, chain transmission it matches my idea of the speedster. Even considering the wheels with the 40x8 tires are huge. My wheelbase is 4,400 mm and I am considering cutting off 400 mm to shorten it. But this is beeing analyzed with some CAD drawings we are making. The proportion has to remain so it does not look weared after all.
