Well here it goes I’m not sure if this is the right place to put this post, it’s more about getting the right information for 1) Safe operation when using a mortising machines. How to get the best performance from the one you have or gathering information if your about to buy one. I picked up a Shop Fox about 6 months ago and I feel I am not getting the most from it because of the finished mortise when it comes off the machine (prior to clean up). Maybe I expect more from the machine then it is designed to provide or maybe I need to improve the way I use it. I think it so that is what this is all about. The second part of this topic should be about storage and care of bits and how to sharpen them possibly the quality as well. If enough information is presented here it will save someone from an accident or save them money or both. Here are a few photos to start of this discussion. ShopFox Mortise Machine
Here is a not so great through mortise

And last another not so great Mortise.
Another not so good mortise.
So can any one coment on these and tell me what was done incorect and how to do it correct next time?
Thanks for your input.

I just came across a modified Delta machine. The head is mounted backwards and the table is adjustable up and down.Modifcation to Delta Mortiser

I like the photo above. I have a Delta and I have a similar vice. Going to have to take a look when I get home.

I’ve been thinking about adding one of these to the shop so I’m hoping this conversation takes off.

I wonder if your drill is adjusted a bit short, causing it to rub inside the chisel and heating it up? I have the same machine you do and it produces great mortices for me.

I have a Powermatic and had the same problem until I played with the distance as Ed has suggested. Also, everything has got to be kept soooo sharp. I was just reading some other post on another topic on the site which stated that prep is everything and this is no exception.

edp, I found that was one problem I had. I did it just as someone told me… “Leave 3/16” at the shoulder then tighten the bit then raise the chisel up”. I burned up the bit anyway. I knew it was not going well it was foolish thing to do that will not happen again. I had this machine about 5 years ago and did not have a bit of trouble, One thing that was strange was the bit was to long for the chisel and bottoms out in the chuck leaving the bit more then 3/8” below the lowest point of the chisel. I did not have the same trouble with the ones that came in a box as a set.

Hey Chip, I spoke to a guy at Woodcrafters and he said a good way to keep them sharp was to sharpen a dowel the same size as the chisel on your sander, kind of like a pencil and run the dowel in your drill press and put tooth paste on it because it is an abrasive and use it to clean the chisel and it acts like a hone. I haven’t tried it yet but I know it works on my table saw to for rust and makes it shine.

I had a hard time keeping my chisels sharp. I bought to cone shaped stones made for sharpening these chisels. They come as a set from Rocker. See link below After using these to sharpen. I take the burr off of the outside with a water stone. This method has worked for me. Good luck.

that is very interesting. My machine has a conical shaped sharpening stone on it for the chisel and the results have been less then wonderful so maybe I’ll try that idea. thanks!

I’ve used the diamond cone stone in a drill press and bring it down into the chisel being held by my hand. Just lightly touch and bring back up, Do the outside on a sharpening stone. I reference an article in woodworking magazine on a reply to Mark’s blog It talks about sharpening and honing , and also clearance between the chisel and the auger.
