Unless you are doing this on an ongoing basis it seems to me it is just as cost effective to have your local machine shop pop them in for you. My guy gets $20.00 to do them, and I do maybe one or two engines a year max, so I just let him do it. Plus, he does them daily and knows how to get them right, something I might screw up doing it infrequently.

I like owning tools, some of which sit for long periods between use, but this is one I don't feel the need to buy.
