POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Today I made a small forest of goofy little trees, two aluminum and two 12L14. The star means they're Christmas trees. I see others knurl the trees, which is a nice touch, but I was too lazy and also thought with the taper I'd probably ruin them in the process. The star was made from a half inch diameter brass round held in a spin indexer, so I could get the outline and then part off a bunch of 'em. The cuts are axial, then I drilled a small mounting hole at 36 degrees spaced appropriately, then parted off to designed thickness. There is a small nub on the apex of the tree that fits the mounting hole in the star, held with epoxy.

Something on the small side...

Learning this stuff as I go, first project is cutting teeny valve gear parts for my HO scale locomotive from 0.02" brass sheet. The siderods have crankpin bearings that make nice radii along the rod, so I'm working with the rotary table. Did some experimentation with various workholding, came up with this:
View attachment 471396

The workpiece is a 2x2" sandwich of 1/4" aluminum and the 0.02" brass glued together. I need to be able to slide the work up and down the X axis to center each crankpin for cutting the radii, so I made a self-squaring fence (has a small key cut in the bottom to fit the t-slot) and a clamp cut specifically to fit the sandwich. Not shown are the 0-80 screws I install in each of the drilled crankpin bearing holes to further stabilize the part as I cut it from the sheet. Haven't actually cut anything with the setup yet, but I have high hopes... :big grin:

I would definitely like to see a write up. Making HO scale stuff is of interest to me (I collect N, but my brother is all HO, and I've never thought of making my own posts, really).

I've been keeping track of what I do here:

It's all 3D printing to date, but I'll do a post on my valve gear milling endeavor when I get a successful part, in a week or so...

Edit: I may make a thread here, if it's of interest. I'm a neophyte at this, so all I say should be taken with a grain of salt. :big grin:

LOL From my childhood, burned into my memory is my Mother admonishing me to "Stop touching the walls!" (bold indicating high volume). She was very "house proud".

I've never been very graceful and at 3/4 of a century old, I use the walls quite often. When I do, I recall and chuckle at her admonishment. He who laughs last . . .

Nice work there.

Knurling a cone requires a knurl of the complimentary angle (cone shaped roller).
Although they are available to buy, I don't think I've ever seen such a conical knurl (tool) in the real world.
Not a vey common tool, IMO. Even an eBay search for "conical knurl" didn't find one.

You're judgement to not knurl was :beer:
 
Holy crap, it's so cool. Most precise thing I've ever made. First thing I ever knurled. Terrible chamfers, but I'll take it. 0XA toolholder. Now to make three more.
