This
is my homemade tool for compressing the rubber suspension cones. This tool has been used
literally hundreds of times. It consists of an old piece of threaded rod of
11/16"Whitworth Coarse rod with three nuts. Any size metric or whatever will do as
long as it is a Coarse thread. (Fine takes longer to use) About 5" from the right, I
have arc welded a 1/2"AF bolt with the head sawn off to the rod. It MUST be straight.
The washers and tube spanner are just packing. The Two top nuts are tack welded together
and also to the rod. The 3rd nut is free to move. The 1/2" nut at this end is purely
to protect the thread when it's not in use.
TO USE
Remove the 1/2" AF nut and drop the tool down
to the rubber cone, carefully screw the tool into the cone, taking care to keep it
straight. Use a spanner on the double nuts to screw the rod home.
Settle the washers down to the cross-member, The
bends in the big washers are caused the first time you use the tool, (which
indicates the pressure involved) after that, just turn
them until they are snug. Now, carefully screw the free nut down to the washers and as you
continue to tighten it the rubber cone is compressed, et voila! - out it comes.
This is a very cheap tool that has been in
continual use for nearly 40 years. The factory tool (Churchill - the only one made
at the time) was about £15. Equivalent now to about £300!
