Schumacher, If it's the same as Big Jim's design then the dimension of the bar are accurately meassured by Big Jim to perfectly fit inside the brush hood so that the hood shape will not deform. That little hole might help too.
Still wonder why they look exactly the same

well i'm sure if big jim measured it accurately then any mug on the street could do the same. just grab hold of a pair of verniers or micrometer and the tolerances would be ok.
what about the play between the brush and the hoood? surely no one can account for that.

That right! Anyone with a caliber can do that but there was no manufacture ever produce the aligment tools with the right dimension until Big Jim talk about it in other forums (and I don't have a milling machine at home). That's what I had been told. Anybody please correct me if I'm wrong.
The play between the brush and the hood can be correct by align each hood individually after the initial alignment like Merciless said.

Trips, I had one with both and what happens is that when you do the one for upright brushes you have very little material left on the sides. When the hole was put in there the material mushroomed out thus causing more work because you have to bring it back into specifications. So we have eliminated it, however that can be changed if there is enough demand.

Actually, the lack of a hole in the narrow dimension is what makes your alignment bar more desirable to me. I think the hole through the narrow dimension weakens the bar too much for my liking.
Thanks for the reply, and if you want my opinion, the bar looks perfect as is.

Dave, we are still trying to finalize everything. I should know more next week.
Schumacher, you are correct. The hard part is finding the correct size.
In regards to brush slop in the hood that is one of the reasons for alignment. You could always pinch the hoods where the brush comes out to help minimize the shift. Just be careful on Epic hoods so that you don't screw up the brush dampner.
Trips, I agree with you about the hole. Thanks for the input.

Are any of you familiar with the tool that Racer?s Edge has been making for years? It?s really a gage for checking rather than an alignment tool. You do not want to bend the brush hoods. Alignment needs to be done by loosening up the screws and moving the hoods. The big handle sticking out of your tool could move the far hood before you get it tightened down. Make a gage like the Racers Edge for the trinity big brush and you will have something nobody else has.

It works just like the trinity tool. I have one of those, and it works quite nicely, plus you get an 1/8" diameter shaft so you can put the motor together without the armature, then slide the 1/8" shaft through both bushings/bearings to make sure they are on center line.
See without that bar, you could have the brushes straight, but have them both off to one side or the other.
