Default Depth gauge jig

I did a fair amount of handheld routing today cutting dadoes and rabbits in some oak plywood that will eventually become two benches with three cubbies each.

One thing that bugs the heck out of me is setting the depth stop on my plunge router. For some reason, I wrestle with it every time and it wins most of the time. Maybe I am just a wimp, but I have a hard time getting the depth just right while working against the springs.

So, come tomorrow, I plan to do some jig building and create a board with some of my favorite depth settings. That way I should be able to just sit the router over the appropriate dept and plunge it until it bottoms out. If I was after 3/8 inch, it should be right on the mark. Of course my jig will only be as good as my accuracy setting it up. I will figure that out when the time comes. May have to use a forstner bit and carefully drill each depth setting.

I will post up my handiwork.
Mike

Hi Mike - not sure what kind of problem you're having. "working against the springs". I just loosen the plunge rod and plunge mine down to the top of the work surface and lock it. I then just put a spacer equal to the depth I want between the plunge rod and turret and lock the stop rod in that position.

The problem with experience is I usually get it immediately after I need it.

Mike, after watching one of Bob Rosendahl's live router demos 17 or 18 years ago, I went out the same day and bought a set of brass setup bars. They can't be beat for accurate standard size(1/8, 3/16, 1/4,3/8,1/2) setups or any combination of those sizes stacked! Most plywood dados I do are either 1/4" or 3/8" so makes it very easy to do as John suggested. I am still using that same set of setup bars today!

I have found that hand tools are the best choice when I want to make mistakes at a slower rate of speed.

I don't suffer from insanity. I enjoy every minute of it.

Those little brass bars and playing cards are my preferred set up tools as well. I use my fingers to see.

Learning is an exciting adventure

Or just bottom the bit out on a flat surface, then zero out the depth guide and adjust accordingly.

By all means get a set of brass set-up bars. In the meantime use the thickness of your drill bits to set the plunge depth. If necessary use playing cards for fine adjustments.
