Egilman Posted April 29 Author Share Posted April 29 Thank you John, Short easy update today, I added the front Wheels & Tires to the chassis since the front Axle are now complete... I used the ones I drew up earlier cause there is really nothing to add from what I had... But, I did incorporate the front end Wheel Camber to the installation... This make her compliant with the real car.... Next: on to the Rear Axle, now that the Front wheel are on she has to have the Rears installed as well.... Onwards....

Egilman Posted April 30 Author Share Posted April 30 Ok, Short update: (adding something I forgot last time) The Speedo Gear to the Right Front Wheel.... I figured I should add it now, so I split out the right wheel as it's own part and added it... I know it's a small detail but it would be noticed if it was missed.... Now, going to pay particular attention to her Rear End.... Onwards.... 1 Quote Link to comment Share on other sites More sharing options...
Egilman Posted May 2 Author Share Posted May 2 (edited) Well, another Update... Rear Axle... We start with the spring plates and model the clamp... Front side.... Rear side... Of course the spring plate is the upper part with the shackles sticking up, and the clamp is the lower portion which has the Lower shock bracket and rear jacking plate incorporated into it.... Between the two of course is the outer casing of the Axle Housing with the large flange serving as the Brake Backing Plate...... It was done this way to allow rotational adjustment to the Axle Housing without affecting the compression line of the spring... Adding a jacking point was a brilliant idea... Mounted to the Rear Springs.... And the backside... Not quite finished, there are more details that will need to be added as the complete Driveline get designed, but this is where it starts.... Overall view... Next up, the Differential housing.... Onwards!!! Edited May 2 by Egilman Quote Link to comment Share on other sites More sharing options...
Big John Posted May 2 Share Posted May 2 Dang complicated design work in them olden days isn't it? 1 Quote Link to comment Share on other sites More sharing options...
Egilman Posted May 2 Author Share Posted May 2 1 hour ago, Big John said: Dang complicated design work in them olden days isn't it? Yep, it was a bit confusing until I figured out what a grease cup was doing connected to the Rear Axle mount plates.... {chuckle} The lower clamp piece wasn't the normal idea of a clamp, more like a bearing cap... This was so the axle housing could turn in the spring mount as the suspension moved up and down.... Effectively keeping the springs from taking any torque.... All the forward thrust went to the thrust Crossmember without the springs interfering.... A good design, I wonder why they went away from it....

Egilman Posted May 3 Author Share Posted May 3 Ok, the Rear end... Front... Rear... Mounted... Reverse low angle... Beginning to look like something I think.... The ubiquitous shot.... Onwards!!! Quote Link to comment Share on other sites More sharing options...
Egilman Posted May 5 Author Share Posted May 5 Short update, Blocking out the Transmission.... In the chassis.... Now I get to work out the details..... And the overall... Onwards.... Quote Link to comment Share on other sites More sharing options...
Egilman Posted May 6 Author Share Posted May 6 (edited) Another short update.... The vagaries of engineering... {chuckle} I ran into a problem with the transmission, parts that I now have info for wouldn't fit on the design the way it was configured.... And I had reached the point in detailing where I couldn't just back it out, and rework it... This is where I finally had to stop and reconsider the design... And what it should look like in real life... Yeah there are issues... So, I started the reconstruction.... This is what was.... This is now.... The differences are subtle, but they make all the difference in the finished model... Everything in the pics has to fit on the model.... This redesign should allow me an easier, more accurate path to the finished transmission.... Restarting the detailing process as we speak.... Onwards.....

Egilman Posted May 9 Author Share Posted May 9 Well four days of working on this, I think I'm calling it done or at least done till something needs adjusting to fit other parts.... I painted it yellow for a beauty shot.... And mounted to the axle/differential... The car was all yellow, with black painted trim but only on the outside surfaces.... Anyway, the Tranny in it's position... And the overall shot, I know too far away to see the differences but I assure you they are there... I'm figuring that it is 95% accurate to what was on the car.... Anyway on to the thrust bushing.... Onwards.... Quote Link to comment Share on other sites More sharing options...
Egilman Posted May 14 Author Share Posted May 14 Well it's been an interesting few days.... It's time for another update.... I know in my last posting I was going to be working on the thrust structure... To do that, I have to get the Differential Housing, Transmission, Driveline Thrust Tube and the Thrust collar to line up properly... So what I do it create a sketch of the layout where each part can be recognized for what it is as well as it's position in the car overall and relative to each other... This is that sketch... Trust me it's all there... (I know a bit skimpy on the lines but what I need to know is present), And indexed to the cars model origin point, so what ever drawing I put this sketch in it will always be in the same model space just by dropping it on the origin point... But when I started adding parts, I found out that they weren't lining up very well... You can clearly see when the layout sketch is shown inside the car, the transmission is way too high... Too much angle for the Differential Housing which drives the Tranny height as well as angle.... I know when looking at the car it looks like it sits fairly lever, and it essentially does... The engineering of it is a bit different... She carries a 1.23 to 1.36 degree forward lean when sitting on all four tires... and the Axle drop angle is only about 3 degrees more or less, so these are such shallow angles that they won't show up in perspective laden photographs... As a result I've spent the last few days redrawing the Differential Housing and Transmission... this is what I've come up with.... You can now clearly see that the Driveline drop angle line runs right down the middle if the Thrust tube.... Just the way it should.... Now I won't bore you with the details of the re-engineering of these things... the Differential Housing was a piece of cake compared to the Tranny... And I'm done with the Tranny, I'm happy to say that I believe it is now approximately 98% accurate... Thanks to the many images I have access to... There is it.... Looking good now, it does match the pics very closely.... Phew I'm tired... Anyway, here is an overall shot, I'm going to get some sleep.... Enjoy... Will start on the thrust bearing when I wake.... (it may take a while) {chuckle} Onwards!!! 1 Quote Link to comment Share on other sites More sharing options...
Egilman Posted 16 hours ago Author Share Posted 16 hours ago Ok Thrust Bearing and Driveshaft Tube... Now on the car the swivel part, (the ball shaped sections) had a black oilskin cover that pretty much obscures the retainer plate and most of the backside details underneath... There was just enough exposed on the current car to give me a pretty good idea of what is underneath... It's pretty straightforward but as far as the reinforcing ribs on the retainer plate, they are pretty much what my engineering background thinks they should be, it is how I would have designed it.. The retainer plate is kinda lite construction as it is only meant to keep the tubes in place... Here is what she looks like with the Tranny and Rear End... Closeup in the frame... The real change is the clamp on collar around the driveshaft tube, it takes the truss rod in the center and the diagonal braces on the outside which slip over a pin that goes through from one side to the other being pinned in place making the complete driveline package a simple bolt in part... It slips into the thrust bushing, bolted to the springs and then the collar retainer is bolted in place... Most of the assembly of the driveline sans engine takes place on the bench... Here is the overall... The intermediate brake shaft crossmember is turned off so you can see the installation of the collar better... Gonna take a day or two, then it's on to the Truss Rods and Diagonal Braces... From there probably on to the Brakes & Rear Wheels... Gradually getting back to where I was before... Onwards!!!

Big John Posted 11 hours ago Share Posted 11 hours ago Fantastic attention to detail EG! This is what I love about this forum is getting to see how some of these classics were designed and built, far beyond what you can find on the net. Model On!
