car ramps

[John Niolon <JNiolon@uss.com>]

oil change bandits are running me off....  35 bucks for an oil change on my
Tahoe is too much...   so I'm going back to home done...   got some plans
for a set of ramps... but before I build I'm wondering if there are any
tips/tricks/cautions/recommendations from the group..   Plan on using 2"
square tubing and angle iron for the material and will be used on concrete
driveway...

make me smart guys !!!
