LHD Gulf Seven

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.

Re: LHD Seven

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.

Re: LHD Seven

I milled a set of aluminum hubs for the front brakes. The parts at the bottom of the photo have been acid dipped to create the finish.

Re: LHD Seven

The front hubs are assembled. Again acid was used to make the final finish.

The studs are the only thing I used from the kit and are a press in fit.

Re: LHD Seven

And the finished assembled rear hubs, studs and rotors. No paint, just treated/raw materials.

Re: LHD Seven

These four corners are ready to be bagged until final assembly of the car.

Re: LHD Seven

I masked off the FORD lettering and filed off the "bolt detail" and drilled for the new hardware then textured the cam cover.

Re: LHD Seven

The lettering was repainted after the final dark metallic gray color was applied.
(The texture looks a lot coarser in the photos than it actually is.)

Re: LHD Seven

I machined the bolts, washers and fittings and installed them by press fit. (Some of them may have to come out later to mount some brackets.)

Re: LHD Seven

I milled the oil cap for it from aluminum; I'll make the decals for that later. This subassembly will be bagged until needed.

Re: LHD Seven

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.

Re: LHD Seven

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.
