problem with 1 3/8 drill bit for IT system.
« on: January 26, 2010, 12:01:39 PM »
my driller drilled out two thumb slugs and put the IT system in with no problem. then the next two the slug went in but wouldnt turn at all. so we plugged them and they worked so we thought the problem was because we were drilling into an existing thumb. but then we did a plugged ball today and had the same problem. any thoughts? cause any little bit helps. also there has been no problem with smaller drill bit

what type of drill or mill you got?

I encounter some when the machine shake too much and the pitch change due to the vibration.
When drilling plugged thumb holes make sure drill is sharp and drill it slow
keep checking for gage for movement.

you going to have to replug the hole and redo it.

and next time before and hammer the safty molloy and can put the top sleeve and the installer and turn it. If it stuck or kind of hard to turn then hole pitch move due to movement.

Use can try using a smaller bit as a pilot hole and follow up with the 1-3/8

We just tried sanding out top sleeve and it cracked a little. should we drill out top sleeve and see if the slug will fit into ball without it and then put a new sleeve in. that way we know the problem is the sleeve


problem is not the sleeve

next time do what tburky suggest it may work

I have found that some of the time the top sleeve will cock slightly when installing and cause the slug to bind. before i glue in the ball-it i use the installation tool for the ball-it as a guide to keep the sleeve from cocking

slow the machine down.

if the top and bottom of the holes are not square then you will have an issue with the thumb being very tight. drilling into different materials will cause this. Also trying to drill to fast and forcing the bit will cause the bit to "walk" a little.

Odds are the ball-IT is off center slightly. Like some have said, this causes the slug to push to one side of the hole.

Very interesting someone said the outside diameter of the colored slugs are different. I've been saying that since I got this kit when it first came out. I have gone exclusively to clear slugs for my customers. But even in some cases, two slugs of the same color can have different outside diameters. This can be a pain in the a** when drilling additional slugs for someone, so I just make sure to check that the slug goes in and out smoothly on their ball before putting a hole in it.

Otherwise, you end up reaming out the sleeves to fit one slug, and then the other slug ends up having wiggle room.

Got off subject a little there, but hey, GOOD LUCK! The IT really is an incredible system once you know how to avoid the common and not so common problems.

should we use standard plug or can you use the one hour plug? and we took out the top sleeve and can see a gap to one side. is it possible to buzz out that one side to make it fit?

yes we watched the trouble shooting video. and it only says something about drilling into a thumb hole. nothing else about it not fitting.

I guess I'd go SLOW with a 1 3/8 to about 3 1/4 deep and then use the bit supplied with the kit.

Its not about how slow the bit feeds but the speed at which its spinning. The larger the bit the slower it should spin to work properly. If your machine is spinning at 400 rpm its bordering on too fast.

so we plugged and redid two that were messed up and did what you said. the first one came out perfect. the second came out super tight and wouldnt work. he used one hour plug instead of full plug. so should we try drilling out the slug and plug that is still in the hole and full plug it and try that. also i changed my pitches from 1/8 reverse to 1/16 forward and 3/16 right. so i have access slug in it along with the one hour plug. so should we try drilling all of it out?
