it’s been a while since i posted anything, busy at work and at home. I have some Vanagon stuff to post and I’ll get on it as I can.
This post is about a bit of fiberglas grating I picked up to use as a bridging ladder. I’ve been looking for off cuts of the is material for quite a while now and last week I finally found some. The source is interesting but I really can’t say where. This kind of bridging ladder is commonly used in the UK and Europe but I don’t see it being used much over here in Canada. Here is a link to a UK source.
What I found was slightly different as what you see on that link, it has extra webbing on one surface and a very coarse anti slip grit embedded on same surface. Also it had been partially cut, annoyingly so as it screwed up a neat division into two long usable pieces. And it is about 38mm thick, major grid size is about 1 1/4″ square. You have to love the mix of measurements.
I cut it it to get one good strip and gave it a test. You can see how it bends but doesn’t break.
They left over strip, still with the partial cut in it, was strong enough to make a ramp.
And the un cut section supports well.
I have to explain why i want something like this. On logging road spurs you often find water drainage trenches cut across the narrow road. Seems to be the norm nowadays instead of installing a culvert. The trenches can be deep and steep sloped, either by design or by the drainage water eroding the sides. Sometimes the shape of the trench makes a perfect tank, I mean, Vanagon trap. You only need a little help to get across and I think even one bridging ladder will do.
