Congratulations! You gave me the incentive to tackle the same thing tomorrow.
Got a pile of goodies from Robert today: 2 mini rebuild kits, grand rebuild kit, another delrin cap, and of course I can't order anything from Robert without a
mod jumping in the shopping cart

.... Yep, I snagged the Tropical Green Blem grand he had up there...
I have an old mini that I need to rebuild, and a grand that probably needs some TLC too... Those will be the weekend projects. I hope I have the same success as you!
