VISE IT legality
« on: December 30, 2009, 07:39:50 AM »
How does the VISE IT system get around the "no interior void" USBC rule?  I believe I read that the USBC specifies that when using a slug you must drill through the bottom so that there isn''''t any isolated voids in the ball.  If you didn''''t drill through and there was a gap between the hole bottom and the slug then there would be a void making the ball illegal.  Well in the IT system it looks like there would be a void around the female screw molley that is in the bottom of the hole once the slug is screwed into it.
Can somebody that is familiar with the IT system give me some insight on this?

im not sure if im making myself clear or not, the void i see is the space between the outer edge of the inserted end and the hole, installed at the top of the hole is the black sleeve which does not go all the way down. So i believe the void is that gap between the outside edge of the insert and the edge of the whole, at the depths below the black sleeve. Does anyone understand what i am saying?

I understand what you are saying.. they are saying that the space is not technically enclosed (which is true) so it isn't a void.. on the side of the slug there is a vent hole that would make the space you are talking about not an enclosed void...

When installing an IT you drill the 1 7/16" hole for a 1 3/8" thumb to the specified height on the drill bit, then the extra 1/2" hole buried down so it can hold the bottom piece of the IT.  After putting the retaining ring at the top of the hole, one inserts the bottom piece of the IT.  The safety device that is inserted into the bottom of the hole HAS A SMALL HOLE IN IT.  This is to inspect the bottom of the hole.  Since one can inspect the bottom of the hole, no void exists in the ball.  

Hopefully this clarifies any misconceptions.
