One of the assembled panels.

These will be painted white with an antique glaze, eventually.

For those taking notes, the tools used on the CNC were a 5/8” diameter Low Helix Up Spiral (2” Active cutting length) for the bulk stock removal and a 5/32”R Plunge Double Ogee bit from Magnate for the profile details.

A 1/32” Onion Skin was left to connect all the pieces which were later separated with a utility knife.

It’s not a sport until someone loses a finger.

I’m glad it worked out, but I hope you got both a discount and an explanation as to why they couldn’t do the moulding.

My current CNC project is in aluminum so it does not qualify as a wood poject.
I am replicating a pot metal lever that cranks an antique revenue stamp machine, however, replicating it as a 3D model for machining has been a challenge.

I didn’t realize that pot metal could be cut on a CNC. I thought it was usually molded. What do you use to cut it?

lumbering_on, I am not machining pot metal, I am machining an aluminum replica of the pot metal part.

He said his project was aluminum. The original he is copying was pot metal.

Ooooops, I didn’t see that he had already straightened out the misunderstanding.

I think you are right, machining pot metal on a CNC would probably generate a lot of shrapnel.

Sorry, I just noticed that when I re-read your post. I’m not a tool-and-die maker so I thought I was missing something – apparently, it’s reading comprehension.:(

Hans,
Replicating nearly anything as a 3D model is definitely challenging.
Is this being done in Fusion 360?”

The modeling in Fusion 360 has been a challenge because I still fall back on the way I did things in Creo even though the basic concepts are the same the methodology and terminology are quite different.

The reasons I am trying this in Fusion 360 are I want to learn how to use it as FREE version of Creo is too limited and Fusion 360 includes CAM. I hope to become as proficient in F360 as I am in Creo so I can eliminate using Creo altogether!

More CNC fun…

Doors by outside supplier, panel inserts in house on our CNC.
Since these are paint grade, they are in MDF. We did a couple others in Alder.
