Gents,I bought an aluminium cutting wheel for my drop saw and can do most jobs with this. Want to rip 1/2" off of say 1 3/4" angle and thought Triton work bench with cutting wheel installed would be good to go to rip lengths off angle to size. I was told to make sure the rpm of the cutter does not exceed the recommended rpm on Alum cutting blade.Checked drop saw..3800 rpm, large Makita circular saw 4,100 rpm. The large blade for the drop saw is rated to 5000rpm.The bloke at the hardware basically talked me out of the work bench but having come home and checked the values I can not see why this set-up would not work. Any suggestions.Happy Festive Season to you all.Mitch.www.thebutterfly.info

Hi Mitch,I have been using a Matika compound saw with the alloy disk. Very accurate, and allows good control over the speed you cut at. It is limited in the length you can cut, however I have not really found this t be a problem as most cuts are across 2.5 box or less. I always cut with a goodly amount of cutting oil, and also give the blade a spray before starting. It makes the cut cleaner and keeps out the heat. This has worked well for me.Cheers!L.Magner

G'Day Lloyd,Thanks Mate, I've been doing same with large drop saw (with Alum cutting wheel). The fellow at the Hardware told me my larger Makita circular saw could be mounted in the same table that comes with the little saw. Seeing as my saw will fit and does not exceed rpm values then I think it should work for those long length cuts. Hope your getting some flying in.Cheers,Mitchwww.thebutterfly.info

If anyone was contemplating it .... don't use a grinder disc!In *non-ferrous* cutting a grinder blade will 'fill' with the cut metal, this in turn will melt and bind the wheel up, ever seen a 2.5 kW grinder bind up on a job? Very messy, both for grinder and operator.Cheers,Nick.

Hi folks, I have been told by a welder mate that to use a cutting/grinding wheel on aluminum one has to put candle or bees wax on it to stop what Nick is talking about. I personaly have not tried this yet as I was only told about it a week or so ago. Happy festive season to all Des Garvin

Nick, you have to coat both sides of the disc from the centre out with the wax not just the cutting edge. Des Garvin

If you tap the cutt'n edge while its spin'n with an old file it'll make it more serrated and won't melt the alu or gum up.Ignorance is bliss............but only till you realise you were.

Somebody forgot to give me all these hints. Mean while I will continue on using my metal cutting disc as I always have. Does not seem to bind up all unless I start going crooked.A drop saw is definately the best though if you have a good qwuality one.Tim McClure
