Thank you for the time you put in to this reply. We pretty much went with as you suggested: "some sort of plug in it and call it a day"
The problem
We wanted to go through the T-Handle but we just could not find a 90 degree tool that with the bit attached would fit inside the hole of the tube...
Yeah, there is no hole between the t-handle and the main shovel shaft. I've pulled off the end caps hoping that was the case but if that was then the rattle would be up in the handle piece and not isolated to the shaft.
That's what I was thinking "right angle tool" but I haven't yet found that tool. I'm going to head up to my ACE Hardware and maybe they have some kind of tool for that. Another person local suggested a demel tool but not sure if that would work because 1. I need to put it inside that 1.25" hole...
Thank you. Yes, we have this option of drilling on the outside of the shaft but we were hoping not to have that hole exposed. The shovels are powdercoated. We have a decal on the shaft that we could use to cover the hole but we are really trying to figure out a way to not have a hole exposed on...
I have a shovel ( actually 500 of them ) that were manufactured with welder's slag rattling around inside the 1.25" pipe. We've since fixed that issue but I'm trying to figure out how to either remove that slag or immobilize it ( ie: squirt some kind of adhesive inside to get it to stick to )...
