After getting the std brakes off the car it is obvious that the std spindle is going to be way to small being 17.4mm at the front and 25mm at the rear with two flat sections and a taper in between. The std FD HUB is a uniform 32.5mm so a sleeve will need to be made up to fit over the 323 spindle. To this end I've been working in Solid Works to CAD up a design for the sleeve. I will use an M33 3mm thread on the end to secure it and will be TIG welded to the standard Spindle.



I've build a parts shaker to knock the edges and burrs off the laser cut parts. I used an old thermo fan from the Mazda and cut 3 of the blades of to unbalance it. I screwed this to a piece of wood with 20ltr bucket on it that hangs from the roof. I'm running the thermo fan from an old ATX power supply that I had lying around. I experimented with both wet and dry sandblasting grit as a medium, the wet medium seemed to work quicker but also the part start to rust. I left the parts in the shaker for about 4-5hrs by which time the edges where smoothed off and some of the surface treatment had lifted. I then coated the parts in Phosphoric Acid (Rust Remover) and coated them in Pentrol pending welding together once dry. If funds allow I'd like to purchase a powered coating gun and powder coat the sub-frame as I have an old oven in the shed I can use to cook it off.
