Drilling upwards through 1" steel plate with a hand-held electric drill is not easy whilst lying on your back. I have to admit that previously this had proved painful and was taking about half an hour per hole.
Bearing in mind, I might have to drill 30 or so holes this way, I felt it was time to think of a better way. For years, there have been stands to convert an electric drill into a pillar drill of sorts but they were designed for drilling downwards (easy!). However, if you play about a bit, it can be adapted for 'skyward' drilling.
And the result is below:

Frankly, I'm really quite pleased with myself for this idea!
