Now you made me feel self-conscious about the 2"W x 1/4"T copper bar I was cutting last weekend. Lengthwise. 😉
Copper bar i have been looking for some. 🙁 got any more ?
No, sorry, only had about a 6" piece but you may still be in luck. I bought mine at the Langely Metal Supermarkets. In your area:
Victoria
(250) 544-4000
2111 Keating Cross Road
Victoria, BC V8M 2A5
or
Nanaimo
(250) 751-2323
2266 McGarrigle
Nanaimo, BC V9S 4M6
Fun place for those with the illness to just browse around. The staff appear to understand. 🙂

Funny i work on bertram place right beside the car auction 🙂 Maybe we can meet up and i can get some cut ? You have more tools ? I have hardly any tool's.
( ps if you need help with other stuff pm me or email me )
Also checkout http://www.onlinemetals.com ...There's some stuff that's cheaper importing, duties and taxes included, compared to Metal Supermarkets 😉

Why would it be a no-no?
jleaman said:How do you get the ends of that metal finished now ?
Is it good to sand blast it to give it that nice finnish?
You can do sandblasting, but before you need to prepare the surface anyway. The easiest way is to use a beltsander with 80-120 grid. You can leave it like that, or blast it later.

Everybody keep in mind... you CANNOT do this with just any aluminum. You must use "free-cutting" grades. Purer alloys of aluminum are gummy and will not cut like this.
Poobah,
Can you shed a little light on which alloys we should choose?
Thanks

yup im on the island ( for some reason i thought you were because you posted the one in vic )
What did you pay for your copper plate ? Are you able to get scrap stuff / what thicknesses ?
Herm and others,
Cutting plate is a little scary at first... it just doesn't seem natural.
You want to make sure your piece has no burrs or anything else that might hang you in the middle of a cut. Be well prepared for the shavings... there will be a lot.
NOW... POST 15 IS BAD NEWS . That piece between the blade and the ripfence is much wider (from blade to fence) than it is deep )front to back). Compound that with a soft fence so the workpiece can **** or twist; the piece will jam and kick. At best you'll ruin your blade... at worse you'll ruin your body. BAD JU-JU.
Bob Ellis,
I'm sure there are cheaper alloys, but I used 6061-T6. Just check to make sure they are described as "free cutting/free machining". These will be more silver in color and less white... a fine line there I guess. If your are using scrap... test a piece first. If it is "gummy" you'll figure it out. I believe it is the 300 series in particular you want to avoid... but don't chisel that in stone.
And guys... you can use your routers with carbide too!

Don't be ridiculous, I do it almost every day. Did you notice a wooden board I'm using to push the aluminum piece?

Agreed. Look twice cut once. In poobah's post it's Look once accuse immediately.

Peter,
There is a right way to do that... and that ain't it.
You can make a fixture where all the wood you have shown is screwed together into one piece with a 3/4" x 3/8" strip on the bottom to fit into the slots on the table. Think about it... damned handy to...
Peter... I can see you have "hands" and a Kung-Fu grip on that metal... you know you're safe and so do I. But that is NOT what you teach others.
Nothing personal dude...

Sandblasting or glass bead blasting. I prefer glass bead blasting as it results somewhat smoother surface.
I have got good results also with "gummy" alloys, using ethanol as a cutting fluid.poobah said:
