Mustardmit Posts: 14 Group: Members Member #3,894 Joined: February 28, 2009	Those compressors you've used, are they "Laser" brand like the ones I'm trying to use to squash up a new (standard) nearside front coil spring prior to putting it in? It sez on the bit of paper "This operation uses up to 1100kg of pressure..." but it's scaring the bejayzuz out of me. Can they take it? I have about 1 1/2" of squashing to go and one of the 'hooks' looks like it's almost off the spring (the other side is firmly on though). There are no signs of bending but I'm crapping myself that something could go suddenly or shatter.

There are no signs of bending but I'm crapping myself that something could go suddenly or shatter. yeah mine were the type with the 2 hooks at either end, looks like they are for larger diameter springs as only one of the hooks sits properly on either end, the other one just sort of touches the coil. The hooks seem to be pretty up to the job, its the lead screw i was worried about as mine started to bend and catch on the hook at the nut end. Plus they got stuck alot, both when taking off the old springs and putting in the new ones, alot of the time i had to just beat it with a hammer to get them off. I dont think i would use the same set again after the pounding i gave them, at �13 a go its worth just getting a new pair next time, or a proper good set if i was going to be doing it often.
