I went to a local factory that makes custom kitchen counters and scored a 1mx30cm piece of some anonymous grey laminate from their scrap pile for free. It's not the famous ebony star, but nevertheless gives a low friction surface and was a huge improvement over the previous material I was using, Teflon on melamine. So +1 to the tips below about going to kitchen places. I paid nothing but brought a little money just in case they asked. I had called in advance explaining that I just needed a scrap of laminate for a project and asked if they had a "bin to raid".

Question on some other stuff:

What would be a good source for inexpensive hex bolts (i.e. 150mm M10 stainless steel). They're about $6ea at Bunnings, but can anyone recommend either locally (Perth) or online a place that can sell them at a significant discount to that? I need enough of them to make it worth my while saving a couple of bucks...

Also, carbon fibre tubes for dobsonian trusses. I've Googled and found a few places that sell 1M lengths. Anywhere longer tubes can be bought at a reasonable price?

Alternatively, since I'm aware CF is still crazily expensive, where's a good place to buy Aluminium tubes for the same purpose?

I've seen it at Small Parts and Bearings in Capalaba (Brisbane). They're a hobby and parts shop (eg remote cars/helis etc), so maybe try something equivalent in Melbourne?

UNC Bolts etc

The Fastener Warehouse is pretty good for UNC fasteners. They are in Brisbane and sell on eBay.

Protective mirror coating, where to get in Oz

I am researching making my own mirror and coating it with silver. So far I have found the chemicals to do it and the how.

One more thing I would like is a coating I can apply myself after the silvering is done.
I could try and get it from the US. Surely there must be something available here. I get my glasses coated, they ask a bit of money for it, but they must use some stuff to coat.
Any ideas?

Coating glasses (lens ) with magnesium flouride mostly I think, is a completely different process as it is to let light through, and chemicals than is used for coating mirrors, which is a thin reflective coating of silver or aluminium over coated by silicon monoxide, as Stephan mentioned.

Where did Stephan mention it? I can't find it in this thread.

Where can I get silicon monoxide, how is it applied?
