[Boatanchors] [Hammarlund] Needed for SP-600

[Al Klase]

OK, OK, I've been trying to stay out of this.

My original Hammarlynd SP-600 cabinet has 10-32 threaded mounting holes, 
so he probably doesn't need J-nuts. This is a standard rack-mount 
situation, so it won't hurt to order fifty or a hundred of the 
appropriate screws and washers.

Once you get beyond the local hardware store, you'll want to check out 
McMaster Carr http://www.mcmaster.com/ They are easy to work with and 
have almost everything. If nothing else, their website is a good 
reference to what exists.

What you need is are "countersunk finishing washers." These are normally 
used with an "oval head machine screws." A flat-head will work but 
doesn't look as pretty.

Many finishing washers are stamped out of sheet stock, and can end up 
damaging the paint of the panel. I much prefer to use plastic (nylon) 
finishing washers. That's what I put on my SP-600 years ago when I 
cleaned it up. I don't remember exactly what the originals were. They 
come in black and white.

My two cents,
Al
