Machining alum parts- wheeeee

[GeneMpls]

I have quite a lot of scraps from my renter next door- he goes thru
a lot of alum- mostly .25 and 1.0 and the left overs go into his scrap
barrels. I have just started machining it. Not sure what grade it is.

I am setting up a wide format printer for the shop (Roland TF-640 (64"))
and build my own takeup reels and IR heaters on the output and extra
media rollers on the input side. I have a bunch of 80/20 extrusions
coming Monday so I figured I would make some alum brackets to
adapt to the machine and different pieces. Hardest thing is holding
down- I used .25 hardwood pins and screws. And some wax he gave
me. Not up to his standards but pretty good for me... and FUN. Gene

Gene, You sound like a kid at Christmas :)
Yesterday WAS a great day for learning new stuff though--dialing in a new 90 VBit and "waterline" marks were horrible--finally after a year I pulled up Paul Z's VBit angle test and found out the bit was actually about 87 degrees!--also found out my 60Vortex Vbit is probably about 63degrees!! Never knew that as I've been pretty lucky I guess.
STILL haven't done metal yet--looking forward(kinda) to it:)
