[DeTomaso] Tapered ring compressor

[Thomas Törnblom]

I have two of these fixed size compressors, 4" and 4.030 but had to get another one for my new 4.040 pistons. This time I bought an adjustable compressor. It looks just like the other ones but it is sliced and has a big hose clamp around it to set the size. I haven't tested it yet but I hope it will work just as well as the other ones.
