No it does not matter what the dia. is, its basically a paper alignment tool.

I am not seeing it. Wouldn’t the bullet need to be turned the other way with the bottom against the screw? Otherwise wouldn’t it crinkle the tail portion? Or a short screw from the bottom?

No, bullet nose in on the screw, paper is aligned on the fence, then with some dexterity you start the roll then pick up both and finish the roll and base tuck. Trick is how much paper you leave out to grasp to get the rolling going.

I received a few email questions asking how the jig is used. Here is a short video that demos how I use it.

It is not a panacea that greatly simplifies the process -- it is just a jig to 1) Align the paper 2) Provide consistent placement of the paper in relation to the nose. However, the trough for the bullet helps keep it in place before starting. Also, the jig can now be set up to roll with either hand (I used to make 2 different models that were mirror images of each other). This video shows me using it with my left hand to roll. By removing the bolt, placing it in the other holder and flipping it around you can roll with your right hand.

The two holes on the sides are so it can be attached to a larger board if desired.

ingenious. I've got to order one; anything to make loading easier/faster, and more consistently. Great design, Doug.

Ok. That makes more sense. I was assuming it stayed on the tray and you just rolled it in the little trough pulling the paper
