What NC Software are you using? Also what control board did you choose for your CNC? I really like seeing what other guys build and I知 thinking about building small CNC Lathe or modifying a Grizzly mini lathe.

Also did you teach yourself Fusion 360? I致e got 30+ years of 2D autocad experience, designing machenery and connectors. Now I知 no longer in that line of work but I致e been teaching myself how to use Fusion 360. It was daunting for a bit, as I would design 2d sections in AutoCAD and import them as sketches into Fusion. Now I知 rapidly getting used to making sketches in Fusion so I think I致e made it past the tipping point. You have inspired me to think about making a replacement stock for my Axis II.

I am using LINUXCNC to run the machine. The setup is a bit more challenging vs Mach 3-4. (Or so I've read)

The 'control board' isn't really a thing in this setup. You can find what I have in my CNC here:
http://www.migration.g0704.com/G0704_electronics.html

Linuxcnc sends step signals out the DB25 parrelel port. They hit the C10 breakout board. The get split out from there to each axis Digital Stepper Driver (Keling brand). Essentially, I bought the Hoss recommended Heavy Duty Digital package when I put this machine together 5 years ago.

I taught myself both CAD and CAM.

The first stock (220 swift) was done in FreeCAD. The friend who's Dad it was made for did 99% of the CAD on that one.

I did all the CAM using a program called CAMBAM. It is easier to learn than Fusion360. However, price and functionality were worse.

FreeCAD is way harder to use. I learned sketches and 3d models in that software. Porting those skills over to Fusion360 w has been a breeze.

The CAM in Fusion360 was the harder part. CAMBAM is much more limited, so you get good fast...not realizing you know very little of true 3d CAM.

CAM is all about knowing your recipes. I used a few test pieces for this stock. One was just 2x4 pine. The other was hard maple, just not the laminated tiger maple Blanks.

I think I've gotten a decent handle on CAM for this project. We'll see.

Man sorry to hear that. What is your router Budget? We have a few Porter Cable 3.5hp models at the shop that are very solid workhorses.

I just want to know where that woodworking shop full of tools is that can be rented for $5/hour.

When I used the CNC machine to cut out the 220-Swift stock (back in 2014) I had made a clamping bracket out of deck-board mahogany. I used this to squeeze clamp the trim router I had (borrowed) onto the spindle of the mill-head. This arrangement worked well enough for the project, but caused a few small issues. I had to slow the acceleration parameters in the control software to overcome the additional weight I had added to the Z-axes. In addition, only small cuts could be made...half due to the trim router limited horse power...and also due to the kinda precarious nature of the clamp mount.

Almost immediately after finishing that stock, I bought some scrap aluminum and fashioned a more robust mount for the larger router I had been given.
This new mount actually replaces the metal cutting mill-head for when I am working on a wood project.
The back plate has the Z-axis bolt pattern cut into it, and the bottom plate has a hole cut to fit the router.
Another mahogany deck-board clamp was made to mate the router to the aluminum plate bracket.

I tell all this back-story and show all this detail to get to this point.
The NEWest router is even bigger...and the mounting plate that I made for it is does not have a big enough hole in it. The 1/4" thick 6061 aluminum mounting plate...needs a bigger hole cut in it.
There are lots of ways to accomplish this...jigsaw, grinder, etc.
I decided to take the router mount off the CNC machine and replace it with the Mill-head...and cut the hole out that way.

I cut both the aluminum plate and the mahogany clamping blocks with the Metal cutting Mill-head.

After all that - trim router, clamp blocks, aluminum mount, bigger router, broken router, redo mount, etc...
But...thats all finally done. Whole evening gone just getting this done.

I dont know if folks are actually reading this.
Please let me know if this is too detailed - or has too many pictures - or is too hard to follow.
I am enjoying the project, and I would like for anyone interested to also be able to enjoy reading about it.

Well I guess as a bona-fide tax payer.....you're welcome! LOL

My neighbor has a 24x40 woodworking shop with all the toys, just not as big as those. 14" planer, 6" jointer, 52" Delta Unisaw, drill press, 48" drum sander, shaper, wood lathe, and yes.....more clamps than you could ever possibly need.

Have you ever thought about using your existing cnc machine to build another larger one. I致e seen some really cool plywood designs that seem to work great.

I知 enjoying this very much! I知 a complete DIY弾r and builder. Avid gunsmith & builder, I make custom knives and build tools like my 2x72 belt grinder. I知 also 100% disabled and have only one arm/hand to use, so building and following others gives me a great deal of confidence. I am a HUGE fan of watching others go through a big project, and the pictures and subsequent stories are wonderful! So I値l say to the OP, thank you very much for sharing this with us.

It is a very special thing to build something on your own. Anything, whether it be a tool, part or machinery...gives one an amaizingly fulfilling sense of accomplishment. It brings a healthy pride that can be shared with, and even help others in their own life. Again I say thank you, and keep it up!

I appreciate you sharing your story. I am just beginning to consider making my own knives. I need a belt sander and I知 considering making my own. Would you mind posting a picture. I壇 love to see it. Maybe start a thread and share some knives too.

Thanks!

Progress continues:

I have ALMOST completed the right side of the stock.
You can see in the picture below that it is very close to finished. 'half-finished'.

However, this wouldn't be the my kind of project unless I made it more difficult than it should be.
The CAD model was actually completed ~3 years ago. My CAD skills were lesser then, so my friend (220-Swift stock mentioned earlier) did the CAD work.
We decided that we could get an 1/8" bit into these front barrel ports. They are purely cosmetic...but were included in the design and shaped and sized for specific reasons.

Well...now that I am actually cutting the thing out, I am realizing that I do not have any 1/8" router bits.
I do have 1/8" 2-flute carbide ball nose end-mills. These would work, but I cant hold an 1/8 inch tool in a 1/4" router collet.

Out in the garage, I happen to have the Roto-Zip that I borrowed from my FIL about 2 years ago. And...it takes 1/8" bits.
All I need to do is attach the Roto-Zip to the CNC machine...

So, I'll just whip up another clamp mount - measure, CAD, CAM, run code...

Couple minutes later...
I have another 'spindle' in another mount. (There may have been some belt sander work for final perfect fit)

Portal CAM G-code made and run:
