Step 1: Pre-cuts and Base Assembly

(Pre-cut materials for easier assembly):

- One 16"x22"x3/4" rectangle (Base)
- Two 2.75"x8"x3/4" blocks with 45 degree angle cut on one of the 8" sides (Base Track A and B)
- Two 2.75"x4.5"x3/4" blocks with 45 degree angle cut on one of the 4.5" sides (Base Track D.1 and D.2) 
- One 4"x4"x3/4" block with 45 degree cuts on two of the sides (Base Track C)
- One 2.75"x3"x3/4" block (Tracer Arm)
- One 2"x7"x3/4" block (Main Slide)
- One 2.75"x14"x3/4" block (Main Arm)
- One 2.75"x6.5"x3/4" block (Spindle Arm)
- Two 2.75"x1"x3/4" blocks (Spindle Arm Spacer A and B)
- One 2"x7"x3/4" block (Spacer Arm)

- Two 2"x1"x1/8" blocks with half pipe cut outs (use 1" PVC pipe to measure)
- One .974"x1.31"x1/8" "C" shaped ring
- One 1.018"x.50"x1/8" ring
- One 3.25"x4.25"x1/4" block (with four drilled 3/8" holes in each corner)

One 1/16" thick Angled 3/4"x36" (cut down into two 10" pieces)

Take the 16"x22"x3/4" pre-cut board (noted above) and cut a 3/8"x6"x3/4" groove to allow a 1/4" bolt to slide up and down (start the groove 1" from the top of one of the 16" sides and center of board at 8")

Draw out and drill nine 3/8" holes to creat a 6"x6" grid in the middle of the board

Install the1/4"-20 furniture nuts to the back side of all nine holes.

Super glue the 1/4" washers on the front side of the board over all nine holes.
<p>I like this design, but i have a question. How does the &quot;engraver&quot; lift up between each letter without creating some type of offset error? Does the whole arm lift up? I need to engrave panels with text and symbols. Could this be done with a 1:1 picture of the design?</p><p>...I hope my question makes sense..... lol</p><p>Jim</p>
<p>May I use your concept for a project I am working on? I am hoping to be able to reverse engineer a template for hex-a-pod legs and need a way to duplicate the pattern once the first one is correct.

This is fantastic! It's like a 'sketch-a-graph' for builders! You've put a lot of thought and innovation into this.
So this is the exact thing I started trying to make and you might say I was failing terribly so I'm going to give this a look over soon.
Very cool project. Can you add some video of this in action please? <br>
