On shocks that load the spring even when the collars are all the way out, a cheap spring compressor is a pair of ratchet lashing straps... not tie downs. Tie downs have hooks. What you want is lashing straps that have a free end that gets wrapped around the "cargo" and then threaded back through the ratchet.
So you feed that free end of the strap through 4 or 5 coils of the spring, then thread it into the ratchet. Do the same on the the other side of the spring with another lashing strap. Slip a piece of carboard or something between the ratchets and the spring so you don't accidentally scrape the spring when you tighten the ratchets. Go a couple clicks at a time on each side, and the spring compresses. When you're done, point everything away from your head, your kids, your dog, and your china collection - release the ratchet - it will go "pop", and then you just take the lashing straps back off.
Even cheap straps will put 150 pounds a piece on the spring with no problems - and that's more than enough to compress a MC shock spring.
