Topic tags/keywords: jig question

Hey guys I have been wanting to build a cnc router for some time now but never got around to it. I think I have seen that you can build your own for much cheaper than to buy one outright. Unfortunately a year ago I became disabled and I cant work right now so I need to build or get one for cheap. woodworking is great therapy for me.

I found this (Milescraft 1298 3D-Pantograph Router Stencil Tracing Jig ) and think it might get the job done. I have to look for someone using it in a video to see it in action. it’s only about $45 on amazon. well within my price range. Any thoughts on it?

Any info is apreciated. I kinda want to build my own cnc router table. that way I can input the image I want to etch into the wood and I can size the table to fit whatever size projects I’d like to do. just dont know what kinda money I will spend.

The least-expensive, biggest bang-for-the-buck CNC router I know of is a ShapeOko, an opensource hobby-level mill.

The basic machine has a roughly 8” x 8” x 3.5” working area and will mill plastics and soft woods (and hardwoods slowly), but it’s easily expanded, and there are a number of options which are well documented on the wiki:

http://www.shapeoko.com/wiki/

People have upgraded the machine up to 1.2×1.2M, hugely increased the rigidity of the machine, and added routers all the way up to a Dewalt DWP611 and Bosch Colt PR-20 (as well as a several kilowatt Chinese spindle) and have cut maple and exotic hardwoods at production speeds as well as aluminum.

A popular configuration is to build the basic machine ($599, though if one is comfortable sourcing electronics this can be much less expensive), then upgrade the Y-axis to 1M by purchasing 2 new rails ($43.68), then double up the X-axis w/ one of the replaced rails, leaving one to spare—- I’d also add metal spacers (a 10 pack each of 1/4” and 1” spacers will fit out such a machine for a few dollars).

You can see my machine (and my notes) here: http://www.shapeoko.com/wiki/index.php/User:Willadams

and I posted my first real project to the ``Dream Toolbox’’ thread: http://lumberjocks.com/topics/48863 (just foam, but that’s a challenge in-and-of-itself)

I’ve tried to put everything I could find into the ShapeOko wiki—- let me know if anything is confusing (or wrong) or missing or could be improved.

Software is a separate concern, w/ a lot of options, but most people seem to be able to find options which work for them.

Wow! Nice looking machine Will. I didn’t know that little ShapeOko could be so nice. Good job!

I got a deal on a CarveWright, which is a bit different in concept than the usual 3 axis machine. I also made sure the upgrades were in place, as well as fabbing a dust collection shoe. It performs well after I figured a couple of things out.

The CNC world isn’t just a pushbutton/turnkey exercise most of the time. You need to wear a technical hat sometimes too… If you don’t wear a DIY technical hat, best to buy a machine with plenty of tech support.

I’m building a CNC router now. When done, I will have around $1500 invested. I’m going very slowly because I am the designer and doing a lot of research. I’m trying to keep the cost down by using off-the-shelf materials and making rather than buying some components.

Since then I’ve finished up that project (milled it out of basswood and flocked it) and done another small one:

Currently bogged down documenting the new SO2 diagrams—- making them interactive w/ highlights—- see Wheels and Carriages and the first two Z-axis diagrams at

The best site for DIY CNC Router information is http://www.cnczone.com/

There are forums for building your own & for manufactured cnc machines.
Anything & everything cnc is discussed.
