Worked well, read the instructions
I bought the jig with the full accessory pack, glad I did, it offers many more options. I found an old piece of 1x12, planed it down to 5/8" and cut it to 5 11" long pieces. Yes, you must always cut a test piece (can be short). You'll also need a backer piece to avoid tearout. Read the instructions twice, they don't make sense until you do it but you need the info. Watched the video. Yes, you hold the jig "backward," pushing it away from you into the router bit. Carefully read each step,and thought about it before doing it. Result: Perfect box first time (except for slight warp in the wood, my fault). Joints are snug, uniform, everything I had hoped for. In this case I didn't even need to adjust the "fit" setting! I'm using it to store disks and belts for my old Craftsman sander.
Hesitated to spend the money but...
After purchasing this jig and watchting the video three times I have made three boxes with very little problem. Watch the video to familiarize yourself with the jig.It really makes it easier to get started. The book should be kept handy for all explanations when the handy quick reference guide doesn't answer all questions. There is a small learning curve to get the fit just right but one set up run through and adjustments made should give you good parts. I have found that you can plan around the set up for the half blind dovetails and you can make differnt size boxes without changing the setup since both parts are made at the same time. With the through dovetails you will have to go through two set ups no matter what but still not that much of a problem .All in all I am happy with this purchase and plan on buying the accessories that give you more flexibility in making other joints.
