Nice improvements you have made. I like that jig, but will just have to wait til I need it for something, you know? If only it could make the Wiley Coyote black circles… ;=)

A good post William, I’ll have to give this a try. For a 1/4” pin to keep the table on my drill press square to the drill bit I use an old broken 1/4” straight cut router bit. It works if you only need a short pin.

if the only demand is that the two ends of the line is meeting each other
then both a triangle and a square looks like a circle :-)

nice jiig William

Am I the only one who puts things up so I’ll know where it’s at? Only to forget where I put it?

All. The. Damn. Time. And it’s frustrating as hell!

DavidGrimes,
It can make Wiley Coyote circles.
Here’s what you do. Set it for a four foot circle. That ought to be big enough. Now set a piece of wood large enough up high, maybe on a set of sturdy sawhorses. Climb up there and cut your circle, but here’s the catch for making it a true Wiley E. Coyote circle. Stand on the INSIDE of that circle while you cut it.
It may not be exactly what you have in mind, but I guarantee you, once you finish the cut, you’ll feel enough like Wiley E. that you’ll have no desire to come any closer to anything he done.
By the way, that was a great response. I love it. I wouldn’t have thought of that one. Were you watching Looney Toons before posting last night?

Devann, a router bit wouldn’t be ling enough for my purposes, but your suggestion did make me think of the several broken quarter inch drill bits I have in a can at the shop. I was planning on sharpening the broken end on a couple of them, but I’ll bet one of them is long enough for what I need.

Dennis, good point. So I guess to answer my topic title question, not all circle are round and my jig won’t work.

dspahn, I am glad to know I’m not the only one, because I seem to do it more and more every year that goes by. I’ll bet if I just stopped everything and went though every can, nook and cranny, and cubby hole in my shop, why, I’d feel like it was Christmas morning I’d fnd so much stuff that I’d forgotten I had.
Let’s see if you’ve done this one.
Have you ever given up on finding something, went and bought a new one, then found the thing you went and bought as soon as you got back to the shop while looking for something else?

Yep! Been there, done that. Then there’s the corollary to these, of which I’m also a victim: You will never find a use for that thing you kept for a long time, thinking it might be useful, until immediately after throwing it away.

Great jig William. Maybe you will dance a jig when you get those wheels made. Great going.

Good hardware stores and even the big box hardware section sell 1/4” pins that are very straight and smooth with beveled ends. I forget what they are for. They might get as long as 2”. McMaster, of course, would have whatever length you want, I imagine.

dspahn,
Another one I have often dealt with. I’m glad to know I’m not alone.
As for the “need as soon as I don’t have” thing though, I have an answer for that one. It’s my legitimate excuse for being such a packrat. I don’t throw away or get rid of NOTHING (within reason of course).
Here’s another one for you.
Read my “on another note” below.
Why is it that if you know exactly what you need to purchase to do a job, you can no longer find that item sold anywhere locally?

SuperD,
I will dance a jig when we get the entire project done. Now I guess you want video of it.

GredD,
Yes, I though about that. It’s another one of those cases though where I have several pieces of 1/4” rolled steele rod at my shop, somewhere.

.

And on another note, I figured out a way to drill those holes perfectly.
Years ago I had a drill guide made by Sears and Roebuck. It was a perfect solution on things that are too large to place under a drill press. Actually, I used it when I used to do mechanic work when I needed to drill out things such as broken head bolts, for example, and wanted to be sure to keep my drill perfectly straight. It’s the perfect solution.
So I went down to the big orange nightmare (Home Depot) to see if they have one. They did not. DRATS! That’s my luck. Of course the local Sears has no idea what I’m even talking about.
So back to the house to get online.
I done a search for portable drill guide, because I thought that was what they were called. Immediately on my screen pops up one made by General Tools at Home Depot. It says my local store has thirteen of them.
Now aint that something. I aint driving back down there for nothing, so I give them a call with the part# and SKU#. And I wait.
And wait.
And wait.
Then the guy says he’ll call me back as soon as he puts his hands on it.
And I wait.
Finally I get that call back. Their inventory computer says they have thirteen of them too. The problem is they cannot find them nowhere in the store.

So anyway, I’m sitting here considering several ideas, of my own and KTMM’s.
KTMM is supposed to be here tomorrow. If I get time this evening though, I may go to the shop and work on an idea I formed in combination of my own ideas, and from the responses I have gotten here.
With a tiny bit of trial and error, I think it’ll be quite easy to set up a pattern, use a pilot bushing, and cut everything we need to do with a straight router bit.
