The ruling to state that you have to enter a dragster is not something that we have come up with.
Silverline have stated this, and they are paying for the hall for the arena to go in to do so.

1 dragster per team is perfectly fine, and I understand your points of view. Even just a belt sander with abit of wood strapped to the side to make it go in a straight line is perfectly fine. No moddification of the actual power tool is needed, no expensive equiptment is needed.

So far the winning dragster is only using very cheap angle grinders, infact almost everyone is. The more expensive hand tools are not worth buying, the cheap versions dont lack in speed and power, only quality (whiuch isnt really needed for this application )
I believe the gadget show will also be there filming and have an entry in the drag racing
