When you are in a situation where the proper tools are not available, sometimes you have to MacGyver it.
I have done a lot of MacGyvering in my lifetime.
In the shop, make sure you have duct tape on hand. It can solve a lot of problems. Just make sure it is a temporary solution. When time permits, make sure the proper solution is applied and the duct tape removed.
One of my recent MacGyvers involved soft ground. At a Vintage vehicle show parking was on grass. It had rained recently and the ground was soft.
This created a problem and caused my vehicle to sink.
I looked around the area and a solution presented itself.
It worked quite well and had no environmental impact.
