Me thinks a valve spring compressor? Shantel doesn't like the engine coughing???
Mike's DIY spring compressor is muy bueno! Thanks again, Mike!
You can probably buy our cylinder plates for less than the rental and return shipping. $39 each

I have already sent drawings to a local machine shop to make my own wobble test fixture.
I would be interested in one if you want to get a price for two. The more they make, the lower the set-up cost per piece and I bet several people would be interested at a reasonable price.
Would you be willing to post your drawings? That would be appreciated!

If you don't use the Lycoming tool pressure plate and remove the valve springs, the dimensions for a DIY tool are given at the end of Lycoming's applicable Service Bullletin SB883C

This is what the Lycoming pressure plate looks like, as it is installed and the screws tightened it depresses the exhaust valve springs. The valve springs do not need to be removed.
A cheap machinists guage clamped in the reference hole works much better than the screw and feeler guage method for getting the wobble number.
If I owned one of those ridiculously overpriced tools, I would modify it to use the dial indicator per the directions in the SB.
