Hey guys, im making a guard for my yz rear brake system. Figured i'd post it here because im sure some of you would be interested.
Okay so firstly i was looking at buying one of these, then i saw the price  $85 plus delivery. So i headed down to the local Aluminium retailer and went digging in the off cuts section and found exactly what i needed. Some 6mm thick plate. (Same as what b&b and force use)
In total, it cost me $6.70 for a plate 300x200x6
I created all the drawings i needed in Solidworks (i like to work off a plan). Here is the initial design i came up with.
After multiple (4) reviews i came up with a design i was happy with. This way all the slots line up with where they would sit on the swing arm.
Next i used contact adhesive to temporarily stick the cutout piece of paper (1:1 ratio) onto the plate using one of the factory cuts as a datum point.
I then centre-punched all the drill holes and internal fillets following all the centre points that were on the CAD drawing.
Then i traced the edges of the cutout with a scriber. And finally peeled the paper off the alloy plate. The adhesive was removed with brake cleaner.
I then took the plate to the shed and cut out the plate into a rough blank.
Then took to the file and cleaned up all the cutouts.
Today i spent a while cutting the slots and then sanding and polishing the guard part. I think it looks pretty good. Best bit is, i made it and didnt buy it.
Tomorrow i will cut this piece out and then drill mounting holes.
I will keep you guys updated as i continue!
