Re: any pics stefan?

2004-08-11 by ballendo

Hello,

You may want to have a look at Markus Zingg's THP setup. He has nice 
board holding clamp which sounds similar to what Stefan has 
described...

Three rods, with half their ends cut/filed away for a short distance, 
and "slider" with three rod-sized holes. With the slider at the top, 
the rods "spring apart to grip the board. pushing the slider down 
towards the board increases this pressure.

If a hole were made in the tank "lid" from which these three rods 
project, then the slider could be actuated without touching any "wet" 
parts...

Just some thoughts on a full moon night<G>
