This was a factory built Caterham model from Tamiya I bought in 2002 so I could display it next to the Red Super Seven I built and heavily modified/detailed to show the difference between what the kit builds straight from the box and the changes I did.
I took it apart and I am going to make it Left Hand Drive along with some other upgrades. I had already begun tinkering with it when I took this picture of it looking like a pile of junk.
If you want to "read ahead" you can see more of this in the June 2017 issue of Scale Auto in the article titled From Right to Left.

I usually start with the wheels and brakes on these reworked or fabricated Sevens, this one is no exception.
I milled these cross-drilled directional carbon rotors from raw stock I cast out of aluminum impregnated resin.

This is the steering rack from brass tube and sheet stock. The inner workings of it are made of rod and tubing.

Painted and assembled. The tie rod halves are pinned so the ends can pivot when the rack is slid side to side. I made the bellows by machining a master and casting them with rubber-like resin that was dyed black.

The front control arms are cast in Zamac as the exact same parts for both sides so the sway bar receiver (on the upper arm) ends up being different from side to side instead of mirror imaged. So I filled them in and reshaped and drilled them to accept the sway bar.
Also the shocks snap onto the lower arms leaving the bottom of the shock eye open, not realistic but easy to assemble. To make it so I can install closed loop shock eyes I cut out the mount from the A-arm and drilled a hole to use hardware like the real cars. I added a brass section to beef up the parts before cut out the shock mount, and to make it look like the beefier optional part.

One of the fenders was slightly damaged during the tear down. (In fact I found several pieces that were broken or cracked at the screw-together points when they were taken apart; probably due to the tightness of the original assembling.)
I also thought they would look more accurate if all the mounting holes were the same. Straight from the kit two "holes" on each fender are actually slots for ease of assembly. I filled them in and redrilled them while fixing the broken piece. I also filled in the holes for the side marker lights and the rather obstinate ejection marks on the underside.
I added seven evenly spaced but different sized holes (larger to smaller front to rear) for letting air out at higher speeds.

To limit the size and therefore amount of debris that could get through those holes I made rock screens from some fine steel hydraulic filter material. Holes were drilled through the screens and then correlating ones into the fenders.
Small clamps to spread the load were made from 0.004 thick sheet plastic.
The screen assemblies are just sitting loose next to their final placement. Mounting hardware will be made later…

The timing belt had rotted and disintegrated (not that I was going to use it…) so I milled a new one from a black zip-tie. Learning from the last time I was able to make this one even thinner so it will wrap around the cogs easier.
http://i.imgur.com/aVCToBE.jpg
I made this jig for the last Super Seven I built to preload a memory into the belt. It will stay in it for a few days in direct sunlight when possible, (instead of a week like last time). It isn't critical for the belt to hug the jig; the teeth will engage the cogs and lock it in place on the model.

Really nice work. What sort of machines do you use to make the parts? With limited space in the future I can see me going down the route of 3d printing rather than a small and probably poor quality mill and lathe combo. Unless that's all that's required for model making.

Scale-Master
07-24-2017, 09:55 AM
I use a Sherline mill and a lathe. I do 3D design as well but have not found an affordable printer that provides the level of quality I want and outsourcing it is cost prohibitive too.

The distributor cap was milled from white resin I dyed gray and poured as a blank. After milling it was polished so it looks like the raw plastic of a real one.
The boots are made of brass.

The front shocks needed to be reworked because the open snap-fit lower eyes didn't look real. This one came off the factory built car I've disassembled.
http://i.imgur.com/V7rwhoQ.jpg
I had a fresh set of shocks left over from another kit. I cut off those lower eyes and replaced them with brass ones. Then I cut the pistons off all four top pieces and replaced them with aluminum rod. The holes that hold the set pins were filled and sanded smooth. The springs were painted with R/C car body paint to flex and I made Koni decals. The snubbers were made from silicone and BMF was used for the spring tensioners. (The rears will be compressed when they are installed.)

The aluminum body side panels have to be installed very early on in the construction of the car. The ones from the factory built car were somewhat bent and dented so they have been straightened out.

The aluminum floor panels are made with holes in them for them to be screwed on to the frame. I didn't want to have those screws showing so I filled in the ½ dozen holes. I had to make some new rivets to replace to ones that got lost during the filling. I dirtied them up following the bottom of my car since it has similar panels.

You bet. I had some of the parts for this one on display at the last GSL. Plan to have this done in time for the next.

I was able to get the half shaft stubs out of the rear end, but the differential cover and drive shaft would not come off without serious damage, so I had to work with them as one piece.
I hand milled (my fingers turning an end mill) the U-joint bearing caps to make the recesses then made retaining clips for them from wire. The dampener flange was cleaned up and drilled for the bolts I milled. Balancing weights were also added.
The differential was textured to look like a cast unit then detailed with more machined hardware including an acid treated fill plug. A custom decal was made for the plug tag and a vent line was added along with a guide and clamp.
