WOOD magazine review

Good all-around value-priced mortiser

Review Summary

+Pluses: It makes accurate mortises and it’s easy to use, but not flashy. The 14-651’s rack-and-pinion fence provides smooth, quick adjustments, and we like its multiposition handle hub. A wraparound door opens wide for easy access to the chuck. The included riser block adds 1-3/4" to the 3-1/4" stroke for mortising taller stock.
Although the hold-down and chisel lock in place with setscrews, the hex wrench for the job is conveniently machined onto the end of the chuck-key handle. –Minuses: We found the Delta’s inline handle grip less comfortable to use than right-angle grips—requiring greater exertion to force chisels into the wood.

Good Tool

Review Summary

This mortising tool work very well if you fists make a couple of adjustments. First is to make sure the hold down is parallel to the bed so that the chisel pulls out easely, second is to have a small space between the bit and the chisel, about the thickness of a dime. The machine will cut fast and true, and well worth the price. It is strong enough not to bend or twist when using it with a very hard wood or the bit is not quite sharp enough. I love it......

14-651 mortiser

Review Summary

My first mortiser but I am very happy with it. Just got done doing 16 1/2" mortises in hard maple with no problem. I made sure the chisel is sharp before I started but that should be standard with any machine. I can't see ever being disappointed.

Delta benchtop mortiser

Review Summary

My first mortiser. Wish I had not bought it. Cheap fit and finish. Put the 3/8 inch in and tried it on a piece of old oak and could not get it to work at all, so I knew the old oak was very hard so put a piece of Lowes 2x4 in and didn't do much better. I had to play with the keyways for several hours just to get the chisel/motor to go up and down somewhat smoothly and 90 degrees to the table.
Although the bits and chisels felt sharp I researched how to sharpen them so ordered the correct stones and sharpened all bits and chisels. Didn't seem to make much difference. Put an engineers square on the table and the right side is 90 degrees but the left side is about 3 degrees off. Since its all one piece I can't do anything about this problem. Work piece hold down does not sit level with the table when tightened meaning taking the chisel out of the work piece very hard. I do like the head turning feature and the spacer for higher work but not have used them since I went back to the router and table saw for mortise and tenon operations. If you read this DELTA, please have one of your engineers tune one and send it to me and I will send this one back, Not gonna hold my breath on that one but if you do then maybe I can do another review and give you a better rating.

Delta Benchtop Mortiser

Review Summary

I got lucky and bought this used on Craigslist...it had never been used so was in like new condition. The previous owner had assembled it so, I read directions and went at it. I cut 20+, 1/2" mortises in white oak with no problems. As with any mortiser, there was a bit of clean up required with a chisel but the mortises were accurate and looked great afterward. I have since cut mortises in walnut, red oak and maple with no issues.
I make sure the chisels are sharp and take my time on the feed rate. I find it easy to position the bit where needed and alignment, hold down, etc. are easy enough. I have never used another mortiser so I don't have any way to compare to others. For me this has been a welcome addition to my shop. I have successfully cut mortises with a router, and drill press and chisel, but I find this a more satisfying method. I like being able to cut the mating tenons on the table saw with no need to radius the mating tenons to fit.
