Aluminum Angle Kit 9

Snowmageddon 2011 hit and I was unable to buy a replacement blade for my band saw until today.  I bought the same metal cutting blade as before, but not without scouring the internet and a local machine shop.  I was really tempted to get something really nice like a bimetal or carbide blade (these seem to be around $30 online).  The local machine shop offered to weld a bimetal one for me for about $80–they aren’t really set up to do this for customers.  I was too impatient to wait for an online order, so I settled with the Lowes one again.

The new blade cuts just as good as before, but made an annoying clunking sound once per revolution.  I traced this down to a piece of dull metal sticking out in front of the teeth at the weld–this was smashing into my aluminum once per revolution.  I ground this off with my dremel tool and it was working great.

I started going back to parts I cut to size a week or so ago and finishing the more complicated cuts.

The curves were supposed to have a 1″ radius.  I found a conveniently sized container with the same dimension and traced that.  I need to figure out what everyone else uses for these types of cuts.  I did consider cutting out a bunch of circles on my CNC machine.

Its fun after reading other peoples’ build logs to finally be building parts I have seen before.  By the way, I have no clue how that yellow protractor thingy is supposed to help me.  I probably need to see someone who knows what they are doing use it.
