Thanks to all that were interested in the Z axis. It was sold to the first responder. Now I'm sorry I had to dissappoint some folks. It goes to show that there is a lot of interest. Thanks Stan Shuford s...@shuford.com On Fri, Aug 15, 2014 at 10:39 AM, Stan Shuford s...@shuford.com wrote:

Brandon, I'm thinking you are getting too fancy if you are adjusting this thing up and down manually. A flat board captured on the sides would create the same motion. You've got a U shape going on right now with your 2 sides and center piece so a captured board makes sense. Also I think you

Hello All, As long as people are looking at possibilities of a z-axis, I always thought that there was some potential in the Angle Ease devices. I'm not sure what the patent covers but for home use, there is no issue.

Hello Tim I have always though that the Angle-Ease-router base is an awesome jig, but I feel that the biggest problem with the plunge routing set up on the Legacy, is the lack of plunge depth (3) , the A-E-R would be great for getting the most out from your router bits, but it too lacks

Hi Curt, to clarify, I said look at it for inspiration, not that the angle ease in it's current form works for us. For example the lamination technique used to hold the router is interesting. The way the threaded dowel pins are used is great for mdf construction. The way the router holding

Tim, I do plan to use a lead screw to raise and lower the router. I just haven't incorporated it into the sketchup yet. I have the locking bolt centered because I want it's force directed between the two angled cuts. The idea is to draw the two angled surfaces together and generate enough

Hi Brandon, You have a cool job! Your statement about over engineering was pretty funny. There's always a huge gap of knowledge between engineers and machinists. I've had the life experience to have both in my toolbox. Now when I design something I step back and look at it from the machining

I haven't considered the pitch of the lead screw. Ideally, it would be one of Legacy's 1/4 per revolution. However, it will likely be whatever I can find at a local hardware store. I keep going back and forth on the orientation of the plates. When I did the sketchup, I invisioned the router

5/8 acme is not available from most suppliers. I have only found one so far. However, you can find 2 start version from mcmaster that are either close or right on to 4tpi. The problem then becomes finding a match nut. If you have a nut it can be used or modified to make the lift work. Finding

In my opinion because I use a plunge router a z axis is only for much greater reach the plunge distance on my router is enough for most operations. That is on the vertical plane but if your router can be tilted to 90 degrees then a z axis is very important for all vertical operations Bill

Bill, What do you think is the proper tpi using a 7-10lb router? I have a PC 7310 on my model 200 that I added a 4tpi screw to control the z axis. Even at this little weight, I can feel the router wanting to drop easily. I have a lock on my axis and I use it with all cuts that are the same
