Northern Industrial Mortising Attachment - For Wood Use Only
Great- Spacers needed
Unfortunately I have a very old drillpress with a rather small collar with which to attach the mortising fixture. However, having machining experience and a small but old metal lathe, I was able to adapt the fixture to my equipment. After this, and other modifications, the fixture performed well.
Modifications required: First, the holes in the base which hold the J-bars were undersize and I had to drill them to size, apparently it got by quality control. Not a big deal, but the average guy might not have the equipment to do that. Second, I had to cut the drill shanks so that the drills fit the distance between my chuck and the end of the chisel. Again, no big deal.
All in all, it works well. The few samples I've made work and look great.

Mortising chisel set
I just received this tool and for the price I feel it was a good investment. But I found that the fit and finish of some parts was lacking I had to tap out all of the set screw holes as they were full of gunk and other debris to the point that the set screws would not work, the chisel holder needed the bore cleaned and deburred ,the chisels need sharpening before they will function properly. So though this tool is worth the price it is not a ready to use as it comes out of the box.

Mortising Attachment Ease
This is a very sturdy attachment to my drill press. Very easy to make mortise joints with. I can't see drilling all the holes and chiseling them out any longer. I had perfect mortises right from the start. For the price this was a great addition to my work shop.

hollow mortise chisel
Good price and shipped quick. I did have a problem fitting the plastic spacer on the drill press as described in a previous review even though my drill press fit the specific measurements noted by the manufacturer. This problem was solved by runner 4 layers of duct tape along the inside of the spacer. With the first use, I noticed that the chisel made an ease cut through maple with a 1/4" bit as well as 3/8" but the edges where not entirely squared. Part of the circular drill bit shows up in the profile of the square chisel bit. Knowing this, I still consider this set a good value and great time saver for stop mortise joint but would consider a different machine for through mortise joints. I also constructed a new fence to ensure an accurate cutting line as the plastic fence in the set was not entirely straight.

The overall experience is very favorable. After lowering the speed on the drill press, I cut some holes on soft pine. The results were favorable. I used the same cutter on my oak project and was delighted withe the results. The cuts were cleaner on the hard wood than on the soft pine! The installation of the attachment took abou 1/2 hr.
And I can say that the overall results were excellent.

Awesome Mortising Attachment
I bought this Mortising Attachment to build a baby bed for my daughter. It worked great and is a good value. There are a total of 128 mortise and tenon joints in the bed and I found this Mortising Attachment to be very durable. It fit my drill press well and made accurate cuts. I recommend clamping the pieces down well because the wood will pull up when removing the chisel because of the tight fit. Overall this is an excellent tool.

Northern Industrial Mortising Attachment
While it took a bit of fussing to fit the attachment to the arbor on my drill press, I finally got it to work. It takes a good amount of pressure to get the chisel to cut into the work piece, I figured out that placing the drill bit at just the right depth in the chisel is is the key to getting this tool to work right. The price of this attachment is unbelievable compared with the cost of buying an expensive mortising machine from a national woodworking chain. I am now making professional looking projects with the best joinery possible.

System will not fit larger chuck drill presses, so be careful your drill press will fit unit. I had to return unit. Quality of components was however very good.

Solid looking build, collar too large
This mortising kit didn't fit my Shopsmith Mark V. The collar is too large for the Mark V spindle and none of the inserts that shipped with it were the right size to adapt to it. I bought this mortising attachment before I bought the Shopsmith, so I wasn't able to check for size before hand. I dug around and found the Shopsmith mortising attachment and it obviously did work.
The build quality seems very good. Double check your spindle size before ordering.

A Great strong product. Found it's parts sharp, well oiled and Durable. Only, when I tried to install it on to my new 79.00dollar drill press off brand. I found the various collars supplied to adapt to the size of the diameter of the chuck mount, to be too small. I'm in a 'pickle'-but found a way to use strips off an old shirt cut to length, to be a good way to safely make up for the space discrepancy. It's been working fine since.
