Thanks for comment guys, still struggling with the base, having a very nice machined piece of aluminum can't figure out how to cut it with the dremmel ...very hard material especially if you no have a clue about.
Match , help please , I have standard cut disks , brown color, diamond coated ones and those with fiber , what speed , dry or wet and which one ?
Googled steampunk; interesting stuff , over the years I've had collected many nice pieces akin that trend.
Maybe later I'll post some pics of my favorites waiting some build to fit.
Old, I'm planning a boat lamp 12V 3 left's Q3s in series based ..
Aluminium can be a bugger...I assume it's an alloy of some sort, and not pure? (pure is a royal pita). Forget the grinding disks entirely. Aluminium can collect in them and cause them to come apart, and considering the speed at which a dremel can turn, that could be a very bad thing. Speaking of speed, you want to use a fast(er) setting along with a high speed cutter. They come in various shapes, but my most used one looks like this:
Not sure what size/shape of a cut you need to make, but for larger stuff don't forget a good old hacksaw and/or holesaw. Most of my rough cuts are done via a sawsall with a multi-puropse blade. I feel your pain...aluminium galls and gums up tools something terrible, so remember:
Many thanks Match. I've not many if any hability with the rotative tool , total begginer. I have one of those from the link below but I'm not so sure what materials can cope , tried soft aluminium 2 mm and work but I'm afraid of try something more stiff..
I don't know what metal or allow this thing is , is shiny like the day was machined , feel like SS and look as hard, working on it appear as a mix of porcelain , lead , SS , glue , kill almost instantly one diamond coated , a nightmare...
By the way I figure out a solution much more elegant , easy and better in all aspects , one wood ring which is aimed to hang curtains...I'll update with the result...
