Strange request I know but I need some advice on how to make beach pebbles out of coloured concrete, or resin. I do a lot of fishing and want to give a pebble weight a go. It needs to be around 2oz - 5oz in weight, casterable and look just like a stone on the beach granite or sand coloured and smooth but i need to incorporate a swivel and loop to attach it to a line so i cant drill into a normal pebble...........If anyone has any ideas to try I would really appreciate, it as this forum is a last resort and im fishing a competition in 3 weeks

There are ways to cast a pebble in resin or concrete, none that simple as you'd need to make a mould ideally from rubber ( cold cure is easiest) and if resin, add in powdered leading to get the weight (trial and error as the chemical reaction in setting will change the final weight a bit). A company called Tiranti's are on the web and do mail order of all you'll neeed including a booklet on how to do it. Process for concrete is much the same except the mould could be made in fine casting plaster with a good release agent.
My advice -don't do it.
It's a crazy complicated task to produce a pebble. Lots of stages can go wrong, the mould not being 'true' enough to hold the casting material, the mould not coming off (in the case of plaster), the casting material not setting and finally the weight not being achieved.
If I were you I'd pursue drilling a pebble that suits - it's GOT to be easier than all this. Jewellers do it and people who do crafts with stone (lamps etc). It's not something I've much experience of but the basic principle is: diamond tipped drill bit on a slow speed with water and NO hammer action.
Gook luck
