    Default scissors knurling tool print HERE

    Some of this is duplicated in my post on how to post pdf files, I aplologize for the rehash.

    I needed a knurling tool and so I drew up the plans and it is this weekends project. In my searches for plans I noticed several requests, but none to be found. In the spirit of the this site's freedom with information and projects, I want to share my plans with all of you here on HSM. So here they are; Evan is graciously hosting the plans as a printable pdf file. Scissors Knurl

    Please note: the axel drawings numbers are for holding the center of the scissors at the centerline of my 13" Grizzley in a 4way tool post. Other than the axel the drawings should be universal.

    As YOD has pointed out, they are also available in this month's ENCO Hot Deals cat. for 28 bucks... But where's the fun in that?

    I bought one of those for work about two weeks ago and let me tell you, I feel like a fool for using the old style knurl for all these years.


    Thanks for the plans, when the shop is slow, I will have the guys make some up for each lathe.

    If anybody else has plans for similar small projects they would like to share I will be happy to host them on my site in the same manner as Rusty's. I will be putting that knurler on my ever growing list of things to do.

    One suggestion, add a hairpin spring to that design to hold them open against the nut. I have a smaller Boyar Shultz sissor knurler that is made on a different principle, and I generally like it better, but the main point is that it has a spring to hold it open and BOY does that make it more convenient.

    The spring is definately a good idea. I built mine a little different. Mine will self align to the centerline of the part and I am not sure that this one will.

    ..........Great set of plans. I bought a scissors type from ENCO. Not the Eagle Rock at $128 but the cheap ones. It works but is sloppy and the knurls do not track in line. The 2 arms are pivoted on a shouldered bolt and the fit is rather casual. The top knurl is about a 32nd behind the bottom knurl. BTW, the knurls supplied with it are crap. Plus the knurl axles are merely pressed into the arms making it a PITA to change wheels.

    I substituted 1/4" drill blanks for the axles, then ground a slot in the side of each to accept a steel shim in the form of an arm that is attached via a button head hexscrew.. This locks the axle in place, yet swing it up out of the slot allows the axle to be simply pushed out for wheel changing.

    I had a couple folks e-mail me about the mod to the scissors knurl, so I'm posting a photo:



    On the left side of the arms you can see the additions. I should have put them on the right side. I pressed out the issue axles, reamed the holes and as mentioned above, used .250" drill blank material for the new axles. With a slot ground in each end, the steel sheet metal 'keeper' sits in the slot and keeps the axles from working out.

    Loosen the buttonhead setscrew and push the keepers out of the slot and then you can push the axles out to change knurl wheels. Since some of the knurl wheels I have are 1/4" wide I made spacers. Merely drilled and reamed some 1/2" drill rod with a 1/4" hole and then parted them off like fat washers.
