I didn’t even think of the pocket hole jig. I’m going to do that this weekend. Great idea. Your frame looks great too.
Just finished the build and it went pretty smooth. Here are some problems and solutions I had. The screws are many and sometimes difficult to figure out. A few extra pictures or a picture of what will be used next can help eliminate the confusion. The chain layout threw me off. Just need a little more clarity or more pictures. I also would like to think of a better way to create that tension. A weight and pulley might work for an even tension throughout the routers travel. The chain tension on calibration doesn’t do small increments. Securing the wires is a must to break the tension from the connectors on the motors and the control board. I used wire staples.
I used my pocket hole drill bit to counter sink all the holes on the front about 3/4 of the way through. I don’t think I will plunge this deep.
Lastly, the sled is still a problem. I think we should offer a sled template in the kit and offer a printable template with drill holes laid out for the router, and markings for the ring and the brick placement.
Here we are completedwith the first cut.
Also, the handles have to be removed. There is a plug that will not come out unless you drill it. I used a small bit to mark center and then a large bit to drill it out. I didn’t have an Allen wrench big enough for the bolts so I used a flat head screw driver. They are in really tight.
Router sled maiden voyage
In the discussion of drilling straight, another neat trick:
Great discussion! With the three boards to stiffen up the plywood, do you think the plywood backer thickness could be down sized or even removed?
One goal of the new frame design was to eliminate the plywood as a structural component. I would keep a sheet of something there (nothing stiffens better than a large sheet) but I see no need for something thick. All the sheet is doing is keeping the frame from shearing and so even the thinnest board would likely work. The least expensive 4x8 sheet of wood material you can find would be sufficient, in my opinion.
@madgrizzle with keeping the frame from shearing in mind, I have done a quick Sketchup model of a concept frame.
I believe this frame would eliminate the need for the plywood backer. In place of the backer is (2) 2x6’s held in place with a dado joint with bolts thru the joint to a flush tee nut and 2 tie downs acting as cross bracing. The reason I would like to eliminate the backer is to make a frame that could be collapsed into movable pieces. I am a Graduate Architect and would like to move the frame between the office and home. I would also use a piece of waste (most likely 4’x8’ rigid foam insulation) between the frame and the work piece but didn’t include that into the images. Any feedback is appreciated.
Good to see an approach from the architect’s viewpoint! Could a single sway brace take the place of the two cable/turnbuckle members? That would add to the lumber to carry, but would reduce the adjustment needed at each setup.
As a graduate architect, you certainly know more about it than I do (just a lowly electrical engineer)… The whole goal is to get it square so if you think it will work doing that, go for it. Certainly seems to be a good away to make it adjustable to dial it in square.
Also, I like the dado idea. I did that with my new frame (used 2x6 for legs and notched it so I could full recess unistrut pieces that span the width of the frame (one at top of work area and one at bottom). My frame is complete and utter overkill…
square is overrated, you need the top beam parallel to the ground and the right
distance out from the workpiece, but (as long as you adjust for the reduced top
height), it doesn’t matter if the legs are vertical or at a 45 degree angle as
viewed from the front, you just shift the workpiece to the actual center of
where you are cutting.
Philosophically, that’s true. But if your frame is square, odds are your top beam is square. If your frame is not square, odds are your top beam is not parallel to the ground.
How square is square? How square is the ground? How round is round?
I couldn’t help it, I had to.
parallelograms have the top parallel to the bottom, without a square in sight
making the sides the same length is critical, making sure it doesn’t lean, much
Good point. Square is overrated.
Kit just arrived and I was looking through bolt together frame assembly. Just curious why you selected three 10’ and two 8’s. It looks like one 10’ and four 8’s would do the same cuts without as much scrap. While cost of wood is only a few bucks cheaper, it’s an easier haul from the store…
