Drilling a hole in a bar?

Use a magnet? Rare earth magnets are mighty strong.

 

Cobalt drill bit maybe?

 

Thanks all, lots to ponder.
I rarely run across anything larger than 20" OD...so
I was thinking a threaded fixture, kinda like a "door-stopper" with a spring on one side and a wing-nut on the other, to tighten it down. The spring would have an insert at the desired length. A short, stout spring would have some flexibility, and a wood dowel to stick in it would /could be considered a consumable item. I'll have to play with a few ideas.
lukem has a good idea, I'll look into strong magnets, that may work without any drilling. BTW.........
How do magnets work?

 

I'm going to try a magnet so I don't have to use he wing nut
to hold the 17" rod on the bar.
Still have a stud to go in the 1/4" hole in the bar.

Ordered 2 earth magnets, 1" diameter circle ,
Will post when I make the new 17" rod.
Will be easier on & off.

Like you idea using a door stop spring.
The rods I've made are from broken graphite fishing poles.
Light & tough

 

If you have an old computer hard drive laying around you can salvage two very strong magnets from it.
I prefer a strong spring mounted to a bar nut.

 

Yea, good point
one slip & your chain & rod could be toast.

 

Hi all, 1st post.. lukem is correct, the neodymium magnets are very strong! There is a firewood measuring tool on ebay that uses one. It looks to be only about the size of a quarter and is rated a 48 lbs pull force. I made one using an old fishing pole and a magnet off a trouble light but its pretty bulky. The results are good though, nice consistent lengths (17") with no pre-measuring.

 

Welcome

 

I dont use these. Just saying I'm not into things hanging on my bar.
