It's raining today and I was looking for a project to do.
Our annual remits this year for FK class included the option to change the (generally very) average PS4002FK hardware over to the better copper kits that are available but sadly this was defeated by democratic vote (you know, the same process that got your President elected).
So I have resigned to simply blueprinting them.
I had a go with the Backtrack tool but it really lacks the strength to do more than just line it up if it doesn't require bending, but much of the problem to me also seems to be the loose fit of the brushes so it really needs reshaping.
This requires some tooling but custom making something would be expensive if you don't have your own tool shop.
Eventually I utilised the following I had lying around.
- JDS C-Can Bushing And Endbell Alignment Tool - JDS-5002
- JK C-Can Blueprinting Tool - JK-BPTool
- Koford Brush Hood Alignment Tool - KOF-M148
I used an old endbell clamped in place as a template to drill the JDS can tool, and carefully tapped the holes with the actual screws I was going to use from the endbell (use oil to lube and make sure holes are deep enough)
Once assembled it needed a .7mm shim (feeler gauge) to support it and 10mm of spacers at the back. The 2mm shaft is an interference fit so can be tapped so as not to protrude out the back.
Now, I can panel beat these into about as good as they will ever be, and it's fully legal adjustment.
Turns out I was glad it rained today...
