pringles, I as well use a number of boring machines for joinery. On my last frame had the chance to see a chain morticer in action. They are simply faster. I found them heavy and my back had issues after extended use. I fixed that some what with a block to stand on. I like the accuracy of the hand crank machine, that is achieved with cleanup by hand tools. I am looking forward to how you make your decision and what your choice will be.
My brother made a hand crank boring machine from scratch, he had $100 in parts tied up in it, no labor number. Tim
