Today I'll be making self locking height adjustment knobs for my Aloris style quick change tool holders.
This is a quick and easy project that I kind of wish that I'd done sooner.
I will be using 360 free machining brass to make beautiful adjustment knobs that look nicer, and work better than the typical jam nut style knobs that come on most tool holders.
Not only is this project relatively quick and easy, but it's a lot of fun too.
The project involves both the metal lathe and the milling machine, and I'll bounce back and forth between the 2 machines.
I'll start off on the lathe, where I'll turn down the stock before giving it a nice knurled texture using a scissor style knurling tool.
Then I'll drill and tap for the 3/8x24 tpi thread on the tool post.
Next, I will head over to the milling machine for some milling, drilling, tapping, and will even get to use the slitting saw.
Once I'm finished at the milling machine, it's back over to the lathe for finishing touches, and separating the parts from the stock using a high speed steel parting tool to perform the parting operations.
I really enjoy projects that make use of multiple machine tools, interesting work holding options, like v-blocks and machinist's jacks, and then produce an immediately useful tool at the end of the project.
The diversity of machining techniques and instant gratification in the result make these some of my favorite jobs in the hobby machine shop.

Who am I?
I'm a hobby machinist, with a passion for old machine tools and manual machining.
I am here to share and learn.
Being self taught, much of my limited knowledge, has come from others sharing their experiences online, just as I am doing now.
My hope, is that by putting my work in front of much more knowledgeable machinists, we can all learn something new together.

My Lathe: MSC / Prince 9517350 - 13x40 Manual Metal Lathe
My Milling Machine: Bridgeport Variable Speed Series 1 "J Head"
My other Milling Machine: Brown & Sharpe No. 2 Plain "light type" Universal Milling Machine
