Access All Areas and Practice What You Preach......
It's the weekend again and a double shift on the Robot done.
This Saturday morning was dedicated to fabrication once again
and my attention was drawn to the rear end of the Robot.
There was quite a large space to be filled and I had discussed
with Adam various options in the past but probably not the one
I chose in a surge of inspiration.
Practice What You Preach.....
Earlier in the year I had tried to sell a mains powered 9"" angle grinder
with a view to someone converting it into a dc powered weapon.
No takers so by means of demonstration and to fill a space on the Robot
I thought I would show how it can be done.
The Grinder which is faulty by the way was stripped to it's component
parts-armature/stator/geabox and casing and a suitable doner dc motor
was found in the workshop.
This was not a straight forward fit, the brass lugs that hold the brushes in
place had to be cut off and the stator had to be sliced in two just before
the gearbox and a universal joint was fitted between the dc motor and
what remained of the stator, the dc motor stuck out of the original grinder
casing too much so I found an old tyre off something I cant remember what
that was a snug fit and screwed it in place using the casing holes and screws.

Access all Areas......
Sunday -Adam and Niall were due a noon so I thought I would have a bit of a
tidy round, It's been a very cold day and I thought none of us will be wanting
to stand outside so I will make a little space in the anex next to the workshop
for Niall to do his soldering ect, I put in a little work bench and a lamp and made
it cosy.
Unfortunatley due to transport delays Adam and Niall couldn't make it today but
the new electrical prep area came in handy for me to test the grinder.
So the question was-will the grinder shake itself to bits due to badly aligned
motor/stator joint-no-it was perfect-no vibration, just a gentle grinding noise
from the grinder gearbox-probably needs some grease.
I turned my thinking to how to mount it on the Robot and once again the
advantages of keeping bits came up trumps.
Adam and myself had gone halves to a trolley jack early in the build but
had to discard the idea, now though the jacks body was perfect for brackets
to hold the grinder in place and by next Saturday I hope to weld it in place
and the fabrication will be 99% complete
