If you are
constructing a frame for a tyre jump it needs to be fairly substantial so
that it doesn't blow over in the wind or get knocked to pieces by a big dog
like Jamie. The design can vary according to the materials you
have at hand but it mustn't have a crosspiece above the tyre.
To make the frame I used the same
principle as in the simple jump construction shown left,
but in
the tyre jump the uprights are longer.
Mine measure 118cm.

For our jump I've used slightly different feet but this
is only because the uprights are lighter than in the original tyre and I
needed some extra struts to give it strength.
The
pipe insulation was easily bent so that the ends could be taped together to
form a hoop. I was a bit stumped as to how I should
suspend the tyre as pipe insulation isn't as tough as a motorbike tyre.
At first I tried to suspend it on chains but the chain pulled through the
insulation when I tried to tighten it up. As Sasha is the only one likely to use it I decided that I could simply tape
it in place with duck tape.

Finally I wound some of the tape
round the bottom of the hoop so that a stray paw would be less
likely to damage it. After a lick of paint the tyre jump was
finished and it was time to try it out on Sasha. The trouble
is she's so quick that we couldn't catch her actually going through
it. The finished jump is shown left and our attempts to catch
Sasha going through it are shown below.
