By Doug Azary - I wish I had one of these slate chassis construction blocks years ago.
I only got this one 3 years ago from a friend and he had owned it for about 15 to 20 years.
This block is set up to make 4 inch and 4.5 inch wheelbase chassis. If I need to make anything
other than that, I have to rig up something, as I don't have any other set up holes drilled
in the block yet for other wheel bases.
The picture also shows what Doug calls a 'jig motor' - he says:
I have now built myself a 'jig motor'. In case you don't know what that is,
it is a motor that you use when scratchbuilding a chassis. It is totally made
up of junk parts that will never be used again. You screw it to the particular
motor bracket you're using on the chassis and it doesn't matter if acid flux
gets spilled on it or if the endbell partially gets melted from the hot soldering iron.
In times past I've usually used the motor that I was going to run in the car as the
jig motor and have inflicted minor injuries on these various power plants. It's not
that I'm sloppy, it's just that sometimes stuff happens!
