RepRap - 3D Printer
Here's my journey of building a Reprap 3d Printer. Took about two weeks to get to the point where I was printing and I am still tweaking things to get good prints but it's working well enough to share :)

Timing Pulleys
I am working on a project for my Enco Mill Drill Lathe - it's a Power Feed driven by a Parallax Propeller and EasyDriver - part of the project involves making some Timing Pulleys to hook it all up! So this post is about the Timing Pulleys! Check out some pictures and videos!

When I was designing my "Ultimate Workbench" I had initially wanted to build in a router table - but then I got to thinking that I already have a router table in my CNC machine! I just needed a way to manually run boards if I wanted to - and here's how I built the manual router table for my CNC machine
First - I wanted something that would be quick to set up and take down, so I came up with these "mounts" for lack of a better word... basically I took a piece of steel and bolted it to a piece of the same extrusion I built the machine from, and then I bolted two pieces of support MDF on to those. Basically what I ended up with was a assembly that I could lay on the CNC machine and slide it into place - doesn't get much easier than that :)
After that I took a piece of white melamine and screwed it (from underneath) onto the mount assemblies - I used the white melamine because I figured it would give me a nice sliding surface
I then routed a channel for the fence - I figure that since I did that using the CNC then it HAD to be perfectly parallel to the machine - so I am pretty sure that my fence is perfectly parallel to the machine... I used a 1/2 router bit and nibbled away at it until it was a nice and tight 3/4"- I will glue and clamp the fence in the slot perfectly perpendicular to the table - future plans are to maybe rout a slot and have another sliding fence onto of this one...
I am clamping the mounts for now - just to be safe, but without the clamps it doesn't move because all the pressure is against the fence, which pushes the mounts into the machine... There is a small chance of movement though so I may build in some quick knobs or something that I can completely secure the thing quickly - but for now clamps work :)
One thing to note - I will probably use the back side of the fence to use as a straight edge to clamp boards to for jointing :) BONUS! :) I haven't tried it yet but I don't see why I can't clamp a board to the parallel fence and run the router in one direction to rout the edge to be perfectly straight - better than a jointer if you ask me!
Ok so that's it for this one - I'll probably be making some upgrades - maybe a sliding fence attachment or t-track miter slot, etc so keep an eye on this one :)
I'll also set up the camera and take some video of me running a few boards through so stay tuned ;)
