I do glue line rips on the Forrest all the time (and have come to expect it). I can't speak to the CMT but I sure like the idea. I can...however...speak to the Delta 6" bench top jointer. Model 37-070 if memory serves me correctly. I had one...it was my first "large" purchase after my Sears direct drive table saw. It lasted one week...the saw lasted three weeks. The jointer did a wonderful job of carving curves...no matter what I did, not matter how I adjusted it, it always cut curves on sticks longer than 2'. That thing cost me about $150.00 in lumber as I tried and tried and tried to "get it right" I never did. I boxed it up, took it back and bought a JET 6" on the way home...I've never looked back.
To me, that little jointer is an insult. I spent so much time annoyed with myself because I simply could not get a straight board. I trusted the tool...it was a Delta...and Delta make nothing but the best right? Nope....as I've since learned, many others have had identical problems with that machine and the only people who get decent results are the people who use them on small sticks. I was so PO'd about the whole thing that I've never bought another Delta tool...I have no doubt that they make good tools, but I'll not patronize any company that puts out crap like that and markets it to the folks who know least about it's capabilities.
Just my $0.02
