Seems every so often I'm making a hitch insert for one purpose or another. So I decided to make this jig to pilot the pin hole in the center of the 2" square tubing. I needed to make a couple inserts with clevises on them for the grass fire rigs, took just about half hour to lay out and make the jig; but now I can set up to drill the pin hole in a couple minutes. Note the bolt to push the tubing into the corner and secure it. You have to compensate for the slight centerline offset in your layout. And if your tubing has a pronounced weld inside, put it away from the corner you push in to.

Simple and very effective. I like the angled clamp screw. I don't many people would think of why that's so important.

Well done.
 
Good setup. Well worth the time and effort to make a good jig for any type of fab work. Especially if you do a lot of it.

When I lived in NC we worked a nice sechule and when we worked our three day weekend. We only had to work two days out of the next seven and still got our 40 hours with the way it worked out. A lot of times on my days off I would go help a friend that worked in the plating, coating rack business. They would build racks to hold anything from sunglasses to JD tractor or combine parts that went through the plating or paint lines.

I built a lot of jigs for him. For when you had to build 500 racks to hold X model JD lawn tractor frames for a trip through the plating (paint) process plant. You did not have time to measure, cut, drill and assemble each rack seperatly. Without good Jigs whats took only days would have took weeks.
 
I'm a big believer in drill jigs.

Any time I have to hand drill anything that needs to be straight and centered, I'll make a jig on the Bridgeport.

Me trying to hand drill something straight... Ain't gonna happen!
 
Now if I could only find that jig I made, last week, a year ago or 4 years ago. I know I put it away in a good spot, if only I COULD REMEMBER!!!!LOL. Nice work Doug. gobble
 
Thank you all for the kind comments. Many times I've heard "work smarter not harder". Dad always said if you want to find the easiest way to do something ask a lazy man. I might be closer to that last one than the first.
 
Can you also get a scrap socket from a junked truck or SUV? There is noting like doing cobbling in your shop. Made greaseable trailer wheels one time. You just couldn't tap the wheel for the 1/4 fitting. Drilled a bit cross eyed hole and then soldered a correct thread nut to the wheel tube. Repainted and screwed in the fittings. Almost looked factory. Many of us wish we had a shop like yours. Talent!
