An update on how my diplomat 430 is going. Well I fitted new roller end caps and it seemed to improve the firmness.. I was going to make a new shaft I had round bar ready to make it with but I found the end caps to be fairly tight.
The shaft has a bit of slap in the bracket so I made up that tool that deejay recommend but i found it hard to slide it along the bedknife cause the reel was getting in road. (have to modify the bolt to clear reel)
I gave the lawn a hit but it was to wet so i just made a horrible mess

seems like if you let the lawn get away on you and you mow it its more prone to getting those lines.
I casted a pair alloy roller end caps at work I am just waiting on the machinest to finish them off. I took pics of the manufacture process for anyone who cares
