To test that everything works before I commit to wood. I printed up a test jig. It needed a little refinement to open up the bores (3d printing is not perfect for dimensions, esp of circles). But then. I could test fit everything.

And it works.

It works better than I ever dreamed it would. The bar in the image slides easily, but with just a quarter turn of the bolt. It locks on place. A quarter turn is all it takes. From free moving to locked. Now I need to buy the wood.

A red 3d printed block. Going through the block in one direction is a polished steel bar. The edge of a bronze bushing is just visible in the block. On top of the block in the far corner a thick washer and a hex drive bolt is visible. The whole assembly is on a wooden workbench.

After I finished work on my primary project yesterday afternoon, I had a bit of time left until the 3d print finished. So I decided to have a play with my new self made sensitive drilling attachment.

Aim was to drill a 0.5mm hole in some brass.

I achieved that with minimal breakage. I've just had a chance to test the hole with gauge pins.

500µm pin fits.
600µm doesn't git.

I'm considering that a big win.

Here is my latest machining project. In the upper left corner it shows a letter holder with handle attached. This four inch, single line letter holder is what my letter sets come with. I made two six inch letter holders so I can stamp book bindings and I made dual line letter holders so I can stamp multiple lines at the same time. The letter slots are tricky because of the small size and tight tolerance. My instructors loved I was making this for practical use. #Machining #LeatherCraft #CAD

Seven pieces of brass. The top shows a single line, four inch, letter holder with letters inserted and handle attached. The next two are single line letter holders, each six inches long. The bottom three are double line letter holders, each four inches long. One is placed on end to show the slats the letters slip into and the threads the handle screws into.

it has been a wild week, on saturday i rescued a beautiful kitty from the middle of an 8 lane highway, on tuesday and wednesday my boyfriend and i dragged home two bridgeport cnc mills that we plan on refurbishing. now i’m sitting on the couch, getting ready to go get some groceries, which is, thankfully, the only thing i have to do today.

i hope to get back to outfit posting soon, lately i’ve just been wearing my “get dirty” clothes, which are now very dirty!

This was on my kitchen counter for 10 weeks filling me both dread and panic that the relative would email. Finally the panic overpowered the dread and I could move forward (#adhd)

And it was simple. #machining "mild steel" was not an issue. Workholding was not an issue--just short enough that a 3-jaw grip and the depth of the headstock were fine

I made him leave me 2 gears to test-fit and I'm glad I did since they turned out to vary by 1-2 thou. Got both fits to "sliding without side shake"
