How to USE & CHOOSE Spring Compressor

Hi guys!

THANKS A LOT for ALL your concerned replies! I finally bought a pair of the cheap taiwan made compressors. If i had the bucks to cough up i woulda bought a better made compressor (for SAFETY reaons!). It has a max opening of 10 in. but has no locks (i will figure out some kind of lock to use). Whats funny is (its really NOT funny) that the few times i used the clothsline "compressor" i got it done with no drama, and the one time (my first and only time) i used a simple wallmounted (non-hydraulic) compressor had the spring fly off, narrowly missing my face and missing someone elses newly painted car by inches (begginers luck?). Of course i`m NOT endorsing the clothsline method...my luck could run out... Again, THANK YOU ALL for all the VALUABLE info,tips and precautions! patrick
