Parts Shaker

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.

Shortening the Diff

I have a Ford 8.8 inch diff from a EF/EB Ford Falcon with a Limited Slip Differential. I want to shorten it down to suit the 323. Due to the RX7 LCA in the front, the front tyres(205X50X15) now protrude from the front guards by 65mm. Making the overall front track width 1,675mm. With 225X50X15 tyres on the rear and the standard diff the rear is 1,610mm. Meaning that the rear track width is 32.5mm narrower on each side. To widen the rear when I shorten it, I'll make the rear axle 65mm wider than the standard rear axle. The standard 323 Diff width is 1,338mm and the Ford 8.8 is 1,547mm for a total difference of  209mm. So the Diff needs to be shortened by 209mm - 65 =  144mm or 72mm per side.

Suspension Design Solid works

To assist with integrating the Mazda RX7 S4 FC front suspension into my Mazda 323, I've decided to see if I can create a solid works model for the suspension and then one for the Mazda chassis to see what fabrication work is need to integrate it. Looking online into engineering tutorials I found a site called Grab CAD community and a tutorial on there around spring design in solid works which looks fairly strait forward. https://grabcad.com/tutorials/tutorial-how-to-model-a-suspension-spring-in-solidworks-and-show-design-intent The main issue I have is the Lower Control Arms (LCA's) are a rather complex shape and will require me to up-skill in SolidWorks to be able to reproduce them. I'm in the process of sandblasting the part and taking some better images from which to model it. *UPDATE -- 1FEB17 nearly finished sketching the LCA and spindles
