Washboard replacement

[WayneS]

We have manage to break one of our Perspex washboards.

I am thinking of replacing them with Polycarbonate but have read somewhere that it does not like UV.

Does anyone have any advice on whether Perspex or Polycarbonate would be best.

Thanks in Advance.

i would have thought polycarbonate was better,its tougher,,you can dril tap,bend it and i'm sure when we used it you could get a uv or semi uv resistant type.we have used it in our doghouse and thats been in the sun etc for over 5 years with no sign of crazing,
it might be worth trying a local sighnmaker for some,they quite ofte use it and often have offcuts

I don't know the answer to your question but why is a Bavaria 33 not a proper boat?

Certainly I'd prefer polycarbonate over acrylic.

It's stronger,
though not naturally UV resistant you can obtain treated material
it can be obtained in tinted varieties
it's half the weight of glass and slightly lighter than acrylic of similar section
it's almost indestructible.

However obtaining solid sheet in small quantities, is fairly challenging. The multi-wall variety is easily available, being used for DIY conservatories etc.

Mick, Just tougue in cheek for all the AWB bashers....

I find it a fantastic boat, having come from a MAB of all MAB's.

Thanks for the feedback Orizaba and Charles.

I will see what PC I can find out there.

If you have any trouble please give me a shout, I am about to get some bits from a local plastics company and would like to test their PC cutting.

Two other differances between perspex and polycarbon is that perspex is more rigid than polycarbon for the same thickness so the chance of polycarbon being pushed out is greated depending in thichness.

Polycarbon tend to be softer and scraches easer

I am a fan of polycarb after replacing all the deadlights on my coachhouse. Easy to work and pliable enough to bend round a camber. No crazing or clouding after three years. I got 8mm offcuts from a local glazier.
But for washboards? Polycarb does scratch easily and washboards would suffer from sliding in grooves and being stowed.
I would go for perspex.

I replaced four of my windows because they were badly crazed. They were ¼" thick tinted Perspex. As an experiment I tried to break them to see how brittle they were - I was impressed how strong they still were, and could only break them by putting in a vice and really leaning on them.
