« Part 1: Router Table Spindle Lock - Improved Part 2 of Shop Made Jigs, Fixtures and Solutions series Part 3: Hexagons, Octagons and Math...oh my! »

Continuing with my router table obsession:

I was flying from Orlando, FL to Fort Myers, FL the other day and this idea popped into my head. I like to make keepsake boxes and with this setup I can adjust the router’s height while the router is on without the danger of raising it too high.

I used a universal choke kit that I bought at Advance Auto Parts for about $12. The digital caliper is from Harbor Freight and was less than $10. The springs help take the slack out when raising the bit height. A pin holds it in place. The spring tension can be released by removing the pin and moving the hard maple arm toward the caliper for lowering the bit.

I have some ideas to improve the design that I will be working on. The family is demanding my attention so I have to go for now.

That is so sweet and simple. You zero the digital caliper then move the height with your hand crank and read the distance directly on the caliper readout. The graduations on the unit dictate the accuracy. Come to think of it you could use a dial indicator caliper too. The thought of taking an angle grinder to cut off the unneccary stainless bits make my blood run cold.

I haven’t been able to get accurate readings repeatedly. The caliper doesn’t move smoothly so the readings tend to jump. the cable flexes too much. The commercial units measure the movement mechanically at the source then send the reading electrically to the read out.
