Oh I definitely understand that I'm not going to get the kind of performance that I would out of a 600 class machine.
I never said 600 machine. Within the same size (450) there is a great variation between brands.
I just want to get it as good as I can. I'll try some extra flybar weight and see what happens with it. I'm guessing a wheel collar on each end is a good place to start?
I guess that you could start with a wheel collar (assuming you have plenty of those on hand), but experience tells me you are going to need a lot more weight than just a wheel collar. You might end up with too many. A proper flybar weight might be the ticket. The weight needs to be concentrated as far as possible from the main shaft. If you add a lot of wheel collars, the weight is going to be distributed instead of concentrated.
As for the thin skin, I'm not taking sides, just advising you to ignore some posts and take with a grain of salt the others. There are a lot of keyboard experts.
