Scale-Master Posted September 5, 2013 Author Share Posted September 5, 2013 Once I got the rear body section mounting points established so I could put it on and take it off the frame and have it line up the same every time, I went back to setting up the rear suspension. I made the upper links that determine where the rear wheels would reside in relation to the wheel well openings. More brass… I also made the outer CV joints and stubs to mount the rear rotors out of aluminum. The CV boots will be soft and dyed black like the tires. The mold has already been made from this aluminum master I turned for them. Quote Link to comment Share on other sites More sharing options...

Scale-Master Posted September 8, 2013 Author Share Posted September 8, 2013 Thanks Guys! The fuel filler is made of brass, aluminum and some soft rubbery plastic that was a tube I had lying around from a paint brush bristle protector. Heating over a candle and bending it like sprue worked well. The filler will be installed in the trunk. Quote Link to comment Share on other sites More sharing options...

Scale-Master Posted September 12, 2013 Author Share Posted September 12, 2013 Thank you Scott. I cast the CV boots out of a rubber-like elastomeric resin and made half-shafts out of brass. Here is one CV/axle assembly and a “loose boot”. The inboard CV joints are already installed on the pumpkin. Here are both sides installed into the car. There is enough flexibility for the rear suspension to work. Top: Bottom: Quote Link to comment Share on other sites More sharing options...

mopar_guy1 Posted September 13, 2013 Share Posted September 13, 2013 (edited) looks incredible Mark! just fabulous scratch building! makes me want to throw in the towel!! You? Throwing the towel..?? You are way too modest. Your work is as amazing as his... I've been doing models since 1980, and I would never imagine attempting building something like you both do. Your work is amazing. I was even surprised to discover another dude that makes something on the same level as your cuda. Yes, Mark's work is magnificent....And so you are....

Scale-Master Posted September 13, 2013 Author Share Posted September 13, 2013 Thanks guys. I had the privilege of meeting Bill and his humbleness was refreshing. No reason to compare, I think Bill’s workmanship is exceptional too. Here’s more boots… Since I was making CV boots, I decided to make the steering rack boots as well. I turned a master from aluminum and cast soft rubber-like accordion boots. Quote Link to comment Share on other sites More sharing options...
Alyn Posted September 13, 2013 Share Posted September 13, 2013 (edited) Mark, the boots look great. With all those ribs, I'm surprised you're able to get them off the aluminum form. The rubber must be quite flexible. Great work in any case. Edited September 13, 2013 by Alyn Quote Link to comment Share on other sites More sharing options...

The rubber must be quite flexible. Great work in any case. Thanks Alyn, But I think you may be missing the process I used to make copies. The aluminum piece is the master. I made a two part RTV mold off it, then I cast the rubbery elastomeric resin from the RTV mold. Yes, the elastomeric stuff can be very gooey and flexible, it depends on the ratio it is mixed. It is actually easier to get the parts out of the mold if I mix it on the firm side. Quote Link to comment Share on other sites More sharing options...

Scale-Master Posted September 17, 2013 Author Share Posted September 17, 2013 Thanks Steve, means a lot coming from you. After I made a few steering rack bellows, I decided to make the rack, but I needed to make the cross member/mount for the rack first. All these assemblies are made of brass, (except the boots). Once I install it into the frame with the engine I can get measurements to determine where the steering shaft will go. This one has some “working boots” on it so I’m not worried if they marred during the building. Quote Link to comment Share on other sites More sharing options...
Scale-Master Posted September 18, 2013 Author Share Posted September 18, 2013 The rack and pinion gears were cut from aluminum and the teeth section of the rack was cemented to brass guides. The rack teeth had to be pitched to match the input angle of the pinion. It does work. It will be snug fit but the steering shaft should clear the alternator… Quote Link to comment Share on other sites More sharing options...

sjordan2 Posted September 20, 2013 Share Posted September 20, 2013 (edited) Astonishing stuff. Just to brighten your day, looks like there's a new Caterham in the pipeline, introduced today at the Singapore Grand Prix -- the AeroSeven Concept, due for production about a year from now. http://www.ultimatecarpage.com/car/5675/Caterham-AeroSeven-Concept.html Edited September 20, 2013 by sjordan2 Quote Link to comment Share on other sites More sharing options...
