Cutting Aluminium Sheet

Looking back through the search function I found this -

Can anyone reccomend where to get any thin 115mm aluminium cutting discs from. Struggling to find any on ebay and Screwfix seem to be out of stock.

Cheers

Dave

Don't know where you can get the discs from but I would urge caution with cutting ali with abrasive discs. If you must take this route be sure to wear a good face mask, aluminium builds up in the human body and has been linked to altzheimers disease.

If you have a 50ltr compressor or bigger I'd say use a body panel saw that takes hack saw blades. You just need to clamp to a table or worktop with a straight edge on top as a giude,makes realy nice curve cuts too. I did a whole set of body panels with half a hack saw blade.

I think we're pretty safe making a few cuts in aluminium That kind of advice is a little dramatic. I've built a dozen furnaces making aluminium powder for both the automotive industry (paint additives) and also for the European Space agency (solid rocket boosters) and the industry isn't filled with lunatics and mentalists.

Although its also worth mentioning that even the government doesn't rate the research.
"It appears that the aluminum content of the brain is less an issue relating to exposure to aluminum than an issue of a blood-brain barrier defect"

Hi Dave

I bought a pack of these Cutting Disks

I know they are maked for stainless but they cut through alloy like butter & made short work of my alloy sump chop
Finding them very durable on all metals & do not clog to badly with alloy like some of the slitting disks I have used in the past.

If you don't fancy using a grinder, a decent jigsaw should be more than able to cut the alloy.
Given a little diligence, quite a straight cut can be produced & can easily be fettled with a flap disk.

Take care using abrasives on alloy .... Decent eye protection is a must, Spent a miserable week once because of alloy particals in my eye .... Didn't care for that too much either

Dust mask too .... I am in the same boat as ASh & David, too late for me

I don't see why advisding the use of a good dust mask is "dramatic". Surely it is just good sense to look after your health so any process that causes dust or fumes in the atmosphere should give cause for using a good facemask just like any process causing sharp particles in the air should be good cause to use safety glasses surely?

Thanks for the info guys.

I think it is good advice to wear a face mask when grinding anything but the Alzheimer's - Aluminium link is all but a myth, there has been no conclusive study which links the two.

I have looked into it in depth as I use aluminium pots to brew beer and wanted to be sure it was safe. There was one study with rats that linked very high aluminium intake with a kind of neurofibrillary tangle but when viewed with an electron microscope were found to be different to those associated with Alzheimer's.
