Admit it guys, who doesn't like putting their hands all over a big fat knob? Now grow up and get your mind out of the gutter! What else would you need a knurler for, but to make various control knobs and such?
Presented here is my own design for a scissor type knurler. It draws upon existing designs and is geared toward small hobby machines like my own. Additionally, there are no complicated parts.
I've attached what drawings I created, and do note that I only use these to assist in the machining. Sometimes I take liberties when I discover something isn't as simple as I thought while looking at the 3D model.
Here's what we're building:
I made parts for this over the course of ... well, I don't remember how long it's been but it's finally done and working so I'm going to skip the build details and just show some pictures.
Some important changes I made, and some I should have:
- Instead of making custom shoulder bolts I made sleeves through which standard fasteners passed
- I made the centre line of the tool the same as the part but the top of the tool should be on the centre line instead.
- Distance between upper and lower arm could be greater, especially for larger diameter parts.
- Slot length in arms should be greater, especially if overall capacity is increased
- Slots for knurls need to be sized to what's available to you
Ok, enough of that boring crap. Here are the pictures...
And why would we build a knurler if it weren't for the need of knurled knobs?
I've gotten tired of my current setup for adjusting the blade guard/guide on my bandsaw. Because of the minor hassle I probably don't keep it as close to the work as I should.
So these were the first actual knurled part I've ever made. Nifty knobs - 4140 steel too if I recall correctly where the stock came from.
