    Re: Toymakers Twin Engine Dragster.......Not just to look at!

    I understand what your saying but............IVO had his 2 450 Cubc Inch Nail Heads hooked up this way, power I'll never match. My feeling is that all the REV (or what I call a slave) engine is doing is assisting the main engine, not transfering full power to the rear end thru the main engine ring gear or ring gears as ea flywheel will have double gears installed. It's like a grammer school science project, thats my hypothesis (I think thats the word I'm looking for) and we will see. No turning back now ;D Rocky

      Well said and thumbs up on your fab work. There is that extra special feeling when building something this epic with your fingers crossed at the end!
      I'm exited for you on this great project.

        Great work - if every "inventor" knew what the end result would be before he started - we would be without many great inventions!

        Worst case scenario if the ring gears turnout to be problematic, you could rig up something using a 4x4 transfer case chain drive or similar. What do the multi engine tractor pullers use?

          I believe they use special gear boxes like Garlits tried on his "Side Winder" but I'm not sure.

            Yep, it's on the ground and ready for the frt axle build but here's the way we got here from where we last left off.

            Lee welded what he could after I completed the front frame bracing.






            The RH rear end bracket was a little more than a 1/2 RD cut as it had to follow the contour of the center section, so I make a little "Widget" to transfer the shape to the plate. Mark your project with line to follw to keep the shape transfer correct. I've used this metHod before on wheel tub projects and works really well and I have layout dye but a good "Magic Marker" works great!


            Once I was happy with the rearend alignment the rearend housing was welded to the brackets after they were bolted to the frame, I used 3/8" bolts for now but they will be increased to (4 per side) 7/16" when finished.

            My alignment tool is all scrap pieces including some old pistons;)
            With this all done I cut some old axles mounted the wheels, and put her on the ground!



            And this ones for you Tom:D

                Another part of the build done, I machined the frt kingpin bosses and bent the axle for the car today. I'm the luckiest guy in the world as I thought I trashed the front axle when I cut the wrong King Pin inclination But luck would have it that I was using the bottom of my 48 F1 axle as a jig so I recut the fishmouths and it fit the Top perfect, should go buy some Lotto tickets:D Original Plan........

                Revised;).......



                Loaded up the car after we finished the front end this week and my son took it to Fomosa today, I can't wait to get there tomorrow night!

                  The dragster looks really good assembled. 8)

                  What sort of machining did you need to do for the kingpin bosses? I get that you had to bend the tube to meet the shape of the F1 axle and fishmouth the ends, but I'm not sure what was machined. I presume you're talking about bushing installation, but I'm not sure.

                  Good bit of luck on being able to use the top side of the F1 axle. ;D

                  EDIT: I'd love to see some detail of the final front axle mount.

                    I had to machine the kingpin boss' (the part the kingpin actually goes thru) out of some round bar. I'll post a followup next week after we get done with the March Meet. I want to thank all the BangShift member support, your interesrt as well as the HAMB has helped me get this far! Rocky

                          It looks just as neat in person. I look forward to seeing it running.

                              Yep, my wifes car, that's my story and I'm sticking to it ;D The car is a late 60's Logghe car I believe and also apart right now, here's a photo of it @ Eagle field in October.

                                  Kinda got stalled after the March Meet, even robbed some parts from the Twin but were getting back on track. I had to remove the small chamber heads off one of the engines for our other Digger so I drug some "461's" out from under the bench, cleaned them up and cut the guides down for Positive seals. I found I'm going to have to make an oil return line off the heads to help get the oil out of the valve covers and the positive seals will help with oil control or lack of.


                                  With our HAMB Dragster needing it's front wheels and tires we bought a set of 17" for our Logghe Car and I put the 18" on the Twin. I think they represent the era perfectly.

                                  With Eagle Field closing in I've had to change my goals to have the car running with the Strombergs so my first step is to finish the intakes. With the runners, mounting and logs all attached I cut out the valley cover out of 10g metal and tach'd it to the intakes while they were bolted to a mock up engine using gaskets. Next weldedthe seam to seal it up, then fabbed the distributor mounting.




                                  Finally finished and back where they belong!
                                  Plans are to get it running real soon and post some YouTube videos! Rocky

                                      Back on Track!

                                      Well after a busy Spring season of events I'm back on track with the Twin, the Twin is on all 4's and made an appearence at the Dos Palos, CA Car show Sat. June 18. We fired it regularly and video'd Fire in the Pipes after dark. Here's some photoss and now it's time to take it apart and get it ready for our Oct 8th Eagle Field Hot Rod Gathering. More to come!

                                          I haven't given up :D

                                          "Hair Pins" and brackets are done and waiting for my son to weld them up, I couldn't wait and welded the Hairpins with the mig but Lee will Tig the rest.


                                          The rear mount is a "Stub" that goes thru the upright and into the x-member.




                                          I really happy with the look, a Radius Rod would of worked but the Hair Pins are the look it needed. Although not an issue with my as there is no front suspension, the "Torsion" arms would have to be slotted for the bolt that that holds them to the axle to eliminate binding.

                                          Blew the rearend apart, took the measurements and ordered the axles today, Lots to Doooooo!
