I am working on scraping the compound on my EE and have run into a problem measuring for parallel on the dovetails of the compound. I am following Connley's book and following the sequence he recommends. The scraping itself seems to be going fine. But when I tried to check parallelism of the compound dovetails a standard mic is too thick at the frame/lock side so that it does not allow the anvil to make good full contact with a dowel pin in the dovetail. I have jury rigged a solution that seems to work. But, I am wondering if there is a better way to do this. Obviously a caliper will reach across the pins and make good contact, but there is no way I could rely on that measuring device for a tenths reading. It looks like I am within a tenth of parallel using this system.
I do not like the fact that you have so many potential sources of error with the vise jaw on which is stacked the dowel pin and then measured with a tenths DTI on a surface gage. I have switched things around left to right etc. to try to make sure that errors are not adding up to throw me off. The vise jaw is parallel within a tenth. The dowel pins measure spot on the same.
Please see pics.
