SV: Burgess vibrator

Hello John,

A Burgess vibrator is something … If
you really want to make one, I can send you the details.

May I be so blunt to ask you to put me on the send list - I’ve
been thinking of building some sort of polishing “tumbler” as I
cant afford to by one now - my budget was eaten by my new rolling
mill.

Being a self taught silver-smith - my problem is that I don’t
know what everything should look like. Your advice would be
valuable!

Best Regards
Lars Dahlberg

I use my mate’s mill!

don't know what everything should look like. 

So am I. But you don’t know how a thing looks - I’ve never
seen a professional polishing vibrator - I just know what it is
supposed to do, which is polish hard to get at items like chain.
Well, here you go;

Get a rectangle of wood about 6x4"by about 3/4" thick and
another similar piece but only about half an inch thick. You
will need a model-motor 4-6 volts, (modelers shops keep all
sizes) 4 springs, fairly light, about 1/2" dia., (I got mine from
the local village garage) You will need a battery charger (I use
the one for the car) and a domestic light-dimmer control. Get an
assortment of around 80 ball bearings from 2mm to 6mm diameter.
Oh yes, a rubber band and an empty Kodak slide box or similar.

Drill shallow holes at each corner of the two pieces of wood to
fit the springs tightly. Fit a disc or something similar to the
motor shaft, and fit a nut and bolt to a hole in the disc to act
as an eccentric weight. Mount the motor securely to the
underside of the upper piece of wood - shaft DOWNWARDS. Connect
the motor to the charger power supply. It doesn’t matter much
which way around you have the leads. Pickle your chains and wash
very thoroughly, dry well. Place in the slide box together with
the ball bearings, strap the box to the top ‘plank’ with the
rubber bands and clamp the bottom 'plank to the bench - it wants
to go walkabout, and switch on. Advance the control very slowly
and you will find a position where you will get maximum jiggling
on the springs, neither too fast nor too slow. Go out to the
corner coffee shop and buy yourself and friend one. Or a beer.
(It makes a hell of a row! The polisher not the beer.) When you
get back you should find your chains beautifully polished.

And if you have any further questions, don’t hesitate to mail me
direct at the address below. But do let me know how you get
on, eh?
