Creating a custom rear axle adjustors or the TT250/Hawk250 etc

the stock axle adjuster on the csc tt250 suffers from a few flaws

1 its small and weak
its small sizes means smaller surface area, resulting in the bolt focusing pressure on a smaller part of the swing arm.

My swing arm has warped a bit due to this. I'm sure its happened to other too. I've never torqued to 35ft.
~ill post a pic after removing the axle~

2 it doesn't line up with the scribes
because it has play as it sits on the axle it might tilt a little in each direction, so its not quite lining up with the scribe. I have to use tape measure to align the chain.

2a the scribes are very faint

the scribes are not easy to see on the swing arm, as a result I have to use a tape measure.

3 it lets in dirt
by exposing the slide in the swingarm dirt gets in. this shouldnt impact anything imo.

How I've gone about resolving this
I've created a beefier design out of cnc'd aluminium (6061).
the design holds on to both the bottom and top of the swing arm, meaning it will always be level.
it should do a better job of distributing the forces hold the axle in play too.
Also it seals the dirt:P

What do you guys think ? I'll be sure to keep the thread up to date as I test out the new adjusters. i'll incorporate your ideas before I get it milled.

(side note: i love my csc tt250. the stock chain is garbage and needs frequent cleaning and adjustment which inspired this )
