Roughing out a head on the relief carving machine. This is a mouse guided machine that allows you to carve sculpture into a 3X3 inch block of material which can be foams or soft woods.
It is very rough right now(10 minutes into it) but will get much better when I switch bits and do some fine scaling to improve the features.
The subject is a angry,snarling and frustrated person, probably an overworked writer or some such......

I have this as one of my entries on the Hackaday contest:

Check out this project and the other machines I have built and give me like on the project!

Hi Folks,
The HackaDay prize contest has started and I would like to ask your support for my projects. And it won't cost you anything.

By giving my project a "like" I get 1$ in seed money to move the project forward add new features, make redesigns and better functionality. I started this year off with some new and fresh machines and ideas to build machines that help people make.


If you like machines and what I am doing, please consider supporting me. I have 5 machines entered, many I have already shared a bit with you.
Here are the links to the projects:

Working with my 3D printed freeform carver machine. Spent about 20 minutes roughing out this head. needs about another hour with some finishing detail and will be done.
Fun for the whole family.........Sculpt anything you like....Or anyone!
Got this machine in the Hackaday contest:

I added a photo interrupter sensor to the manual drives so they can be tracked. The photo shows the TTL DRO I designed for my other machines reading the sensor from the axis. I like the TTL DRO as it uses a VFD display which has high visibility and easy to read in any light level. I also have a arduino/LCD version.
The optical wheel has just one slit to count a single rotation of the handwheel, but more can be added for any desired resolution.
This make it easier to repeat parts and operations done on the lathe.

3D printed mini lathe-New spindle/Headstock motor assembly.

I made a whole new spindle assembly for the mini lathe using a 775 DC motor. Normally on these machines I had been using brushless DC motors(the type normally found in printers), but they can be more costly and harder to find and buy reasonably and more difficult for people to reproduce this machine.
I selected the large 775 motor as it has massive torque and infinite variable speed using an inexpensive off the shelf speed controller.
The motor has been fully enclosed in printed parts and rigidly mounted to the base for machine mounting.
It is directly interchangeable with a common footprint so either motor can be used on the lathe.
The new motor has more torque, higher RPMs and is cheaper(8-10$) as well as being readily available from many sources.
The arbor adapter can still hold all the same accessories as the original.
The second photo shows the old version motor for reference.

Turning a part on the new 3D printed manual lathe. Works great and fun to crank the knobs once in a while......I will be back on my joystick operated ones next week though........
