Recently I rebuilt the BRS mount on my Mk 3, moving it forward and down and reducing the part count. While finishing up other projects, I've put off trimming the gap cover to fit the BRS's new location until yesterday and got a nice surprise.
If you are an HFT customer and you receive the e-mail sale flyers you've probably seen the diamond coated cutoff wheels they occasionally offer at a discount. Normally they sell for $9.95 for a package of five, but on sale they are marked down to $1.99. These little wheels slice right through .06 Lexan like the proverbial hot knife and the butter. And, better yet, they last. I cut about 30 inches with the diamond wheels buried in the cut, plus a fair amount of trimming and it showed no sign of wear or build up of sludge to the wheel. When I went after the aluminum angle that frames the gap seal the wheel began to show some wear but was still hanging in after a couple of inches of .06 aluminum.
I'm not a share holder or agent for Chinese commerce, but these little buggers are really nice and dirt cheap at the sale price.

Why would you use a Diamond wheel to cut Aluminum ????
Seems like it would just "Gum" it up....
They make stuff that coats an abrasive wheel so that it won't gum up
Sometimes WD-40 will work too....

Way back in the beginnings of Vamoose, some "friend" told me to use a router
to cut thin sheet aluminum, so I gave it a go. It worked ! ! ! Cut that
there alumineeum like cheese.........but cleanup was a beast. Man, did that
ever make a mess. Lar. Do not Archive.

The problem with trying to cut aluminum with a router is that you have to do conventional cutting (going against the rotation of the cutter). The chip is carried around to the material and gets friction welded to it. Router bits are usually reverse spiral, too, and that doesn't help the problem either. If the cutter is buried in the material you can climb cut and that helps a lot, but if you come far enough out and the cutter grabs, watch out.
As for cutting aluminum with a diamond wheel, the edge began to break down, but it didn't gall up at all. My only excuse is that I was working on the floor of the hangar, my back was killing me, and what the heck, I've got about 50 of the little buggers, so I just plowed on through.
You're right, WD40 is a great cutting lubricant as a quick and dirty method, but kerosene with it's oily base seems to stick a bit better.
Ah, memories. Cutting 2" aluminum tooling plate with a worm drive saw, a carbide blade, and a spray bottle of kerosene in the Kansas summer sun. Way too much fun.

"Way back in the beginnings of Vamoose?" -- I didn't think routers
had even been invented that long ago --

Right now, the bird lives in California, and the Lar lives in New Mexico.
Not likely to change for a month or 3. Do not Archive.
