  • works great

  • It worked but…
I used this mortising setup on a drill press. But based on my experience I can’t imagine how it would work in a hand drill unless you’re mortising balsa wood. I found it takes extreme pressure to push the chisel thru fairly hard pine, and you have to clamp down the workpiece with 3or 4 clamps to keep it from riding up when you retract the chisel bit. Overall it got the job done but took me hours to set it up and get it working right, so I left off one star. ... show more

  • Not worth it.
Does not work as advertised. Directions are not helpful. I don’t give many bad reviews so use this review.

  • Drill press to motis machine
After getting it set up I was able to make very decent motis and tendon joints. Great for a hobbiest woodworker on a budget.

  • Great product but crummy packaging
Product worked great AFTER I found additional bolts that had slipped out of the box during shipping. Sort of sloppy way to treat a good product.
