Pet Forum / Aquaria / Marine Reef / July 2004making circles
well I am not sure if you lot will think this is of any use but. I was chatting with a guy about milling large holes and needing large cutters. He suggested that if I got a rotating table and a 6mil cutter I could cut any size hole. so to cut a perfect round circle all I need to do is hold the router and spin the work around under it then it will cut a perfect circle. I was thinking about DIY skimmers David > well I am not sure if you lot will think this is of any use but. > [quoted text clipped - 6 lines] > > David core drills. a fly cutter is used for metal or wood large holes. that won't work well for glass. > > well I am not sure if you lot will think this is of any use but. > > [quoted text clipped - 9 lines] > core drills. a fly cutter is used for metal or wood large holes. that won't > work well for glass. that's my point if you turn the work you don't need loads of different drills just a router ? be hey its was just a suggestion David > > > well I am not sure if you lot will think this is of any use but. > > > [quoted text clipped - 18 lines] > > David no. a router won't work for glass. it may for acrylic, but it's a lot easier to get a hole saw than to get a precisely turning table and be able to mount and secure a glass tank such that the center of the hole is exactly over the center of rotation. iow, no it won't work. > > > > well I am not sure if you lot will think this is of any use but. > > > > [quoted text clipped - 28 lines] > > iow, no it won't work. no it wont work for glass I would use a glass cutter. But it would work for Acrylic. not seen many glass skimmers. I was thinking of two bits of ply with nut and bolt in the centre some double sided tape but then I am into DIY and like to have fun my tank is 6 foot long how do you think I could spin it around :-) come on be serous smile a bit please. David A decent sized glass shop will have a water cutter, this will cut your circles for you. There is no way to do it out of glass by scoring and breaking AFAIK. There is no reason a skimmer needs to be round, it's just looks neater and more professional as it is the industry standard. Just do it out of square stuff if you need too.

To find hundreds of places with abrasive waterjet cutters, visit: Job shop listings: ================== http://www.waterjets.org/waterjet_jobshops.html http://www.waterjets.org/waterjet_jobshops.html http://www.omax.com/job_shop_match.html Note: Ask to make sure they have experience with cutting brittle materials first. For glass cutting, the machines must be capable of low-pressure piercing.
