Just gauging interest at the moment.
I have built myself a workbench/table/soldering station for use when working on and under the playfield.
As you can see, when placed over the table it provides a horizontal surface to work from, place nuts, screws, bolts etc. as well as tools you are using. It has beading along the long sides to stop items from rolling off, but open at the ends so small fiddly items can be slid off the end.
This fits perfectly on standard sized tables, being perfectly horizontal on Stern tables. I am working on an adaptor to allow it to be horizontal on older games. As can be seen from the last picture it also stands horizontal on a flat surface (meaning I can now solder on the dining room table without fear of burning it!)
£30 with attached soldering iron holder - £25 without holder.
PM me if you are interested.
