[pure-silver] Re: WTB Dry Mount Press

All a lot easier said than done. These imperial nuts are tough to get even
in the US (little to no chance here in Germany). These nuts are very thin
(just 3 mm). There is no nylon replacement nut available and there is no
space or clearance to add any washers or add counter-nuts. Also, since the
housing is aluminum and the bolts are steel, I'm not sure if grease could
make things worse and cause corrosion? I remember side strip on automotive
doors falling off, because the door was aluminum and the fasteners were out
of steel.

Anyway, none of these action should be required for a press, retailing
around $2,000. It functions well as a dry-mount press, and I don't know of a
better one, but the mechanical design leaves something to be desired as far
as quality is concerned.
