I use to work out in the "field" ............
No I did not pick cotton ........
No I did not plant corn ....Don't get me wrong, I love our Mom and Pop farmers, (sadly said as we lose them too regularly).
The "field" is a place where you go to do work away from a home base.
In the late 70's, 80's, and early 90's most of my work was out in the "Field".
This jig was the perfect tool for cross cutting plywood without a table saw, or just cutting off the last 2" of a 4'x8' piece even with a table saw at your disposal. I have used the concept for cutting diagonals and drop cuts. It has been used during my solid surface phase, and now more reguarly use in cutting face plates for audio video components.
Here is the before and after photo of the console/credenza with the adding of the "plate around the face", correctly stated the faceplate around the components.
The jig used here was with a router but the concept is the same. It's construction can be found in the thread "Plate around the face" here in jigs and fixtures. In this thread I will show you the simple making of a straight edge for the circular saw.
I feel fortunate to have had the opportunity to work with some very skilled craftsmen who took pride in their work and were willing to share.
I truely believe we need make our own jigs if possible.
I like making my own jigs because understanding the way they are made allows me to modify them for multi purposes, besides, I make things with wood and why should I buy something I should MAKE!
Since the 70's I have probably made jigs using this CONCEPT... 35 to 70 times. I made two in the last week, one for a little 4 1/2" worm drive Rockwell and one for the trim router.
