Hi.
Ok - we use Danage foam targets for our targets. We have a system to maintain the targets, by drilling out the weared out center, to drill out replacement centers in a reserve foam matt and put them into the targets. This system is a relative cheap way to prolong the lifespan of a 44x44 foam module. Because each core drilled out of the reserve foam matt, costs appr. 25 DKK (2,71 GBP) (if 10 cm in diameter). The thing is that we drill the cores out by hand, and that is a hard job. How to do it in a easier way. Maybe we can pick each other's brains and come up with a good solution that is inexpensive. I have been looking at drills that can be mounted on a regular drill machine - but they are quite expensive. Plus they have a center drill, that makes a hole in the center.... (Maybe that's why it is called a center drill....).
Since this is a leverbow community, another thought of course also crossed my mind: To use lever action to press a circular blade through the foam. But how much force is needed to press through 245 mm foam?? The disadvantage with this is also that this would not work on a vertical surface like the foam wall - only on the reserve foam matt.
So come on clever guys and girls! Somebody have a great idea?
