R7s test jig

Here you can see my R7s test jig. It is made from one holder on each side made of paxolin that holds two 10mm stainless steel bars. There is a paxolin slider that can be fixed by a screw.

I hade made a simialr one for fluorescent, but it was to flimsy and unstable and so it was ultimately scrapped. However i am nu Building a new one for uorescents with a solar profile as base.
