Do not pin or set screw the axle.
Axle must be solidly tight. You will get some weird flex and gyrating if loose.
The best way I have found is turning a step on a spacer and press bushing into stay method.
In mine I was able to up-size the seal and that gave me the meat (metal thickness) to work with.

That axle is tight.
Stepped spacer.
Bushing pressed into stay.
Trapped between rocker side and step shoulder. And by trapped I mean just enough clearance to rotate freely on the stepped spacer.

I said set screw for the axle as I seen it being done, and it might have been on the Triumph search. Some do odd different things. I looked at it as the extra measure to help secure the axle distance between the rockers. Just say you have 7" distance needed for everything, even that little extra clearance for free movement, you tighten up the axle nut to that key position, and I thought the set screw just help held all in that position just in case the axle nut backed off for some reason.
Not done, just a thought, so eliminating that thought.
Now on to the brake stay set up. I see what you did, that is the ticket. Just turn the OD of the spacer down enough to hold the bushing on the end. Nice tight fit so bushing is not rolling on spacer, spacer cut to correct length hold the brake stay in it's positon, no side to side movement.
I see this all working. Now I will get to the drawings and material and see if I can make it work. I have to have enough metal at the lower end of the brake stay for the larger bushing dia.
I need to do this, getting this nasty feeling in my stomach, like I may not have enough material for such a correction.

The nut does need some kind of safety back up.
A lock nut, a castle nut and cotter pin, ect.
Something that if the nut gets loose it dont fall apart.
I suppose a set screw in the right place could do the same thing.

The Dewalt 1/2" bit took forever to punch through, but got it done, started on the 5/8" step.
Now I checked it out, if I go to a 1" hole in the brake stay, than I have 3/16" thick distance to the outer edge of the pattern. And I corrected myself, press fit bushing into brake stay and let the bushing roll on the stepped spacer.
I did some looking for spacer's, did not make up my mind yet, as the available size varies on what type of material, so first I need to find one large enough for what I need.
If I go 1" OD on bushing with 3/4" ID so I have 1/8" wall on bushing, well the spacers wall thickness will only be 2mm thick for the 1/2" distance the brake stay and bushing take up, than the spacer steps up in OD and a thicker wall, but for only 6/16" of an inch, the total length for the spacer is 7/8".
More drill press time.

Still on the drill press, but when I was thinking about it all I do believe that the meat of material should be on the step spacer, if the flanged bushing is to revolve on it.
So I have the flanged bushing with a 1" OD and a 7/8" inner dia., custom cut to 3/8 " long for the brake stay, bushing press fit into brake stay.
The 1 1/8 " OD spacer with the 17mm ID will have 1/2" of a end turned down to the 7/8" dia. for the brake stay bushing. This basically gives a little over 1/8" thick spacer wall where the flanged bushing will ride. I am still looking over McMaster site for what is needed.

sounds like you have got it figured out.....I would not want any less than 1/8 wall on the spacer, that said, there is very little clamping force on the axle bolt/nut. But you don't want a thin spacer compressing and making for a loose axle bolt. There may be torque figures for the bolt. maybe Rex has a figure. On my setup the spacer for the wheel bearings was about 1/8 wall if I recall correctly.
I do not like, or trust nyloc nuts......I use castle nuts and cotter pins, maybe old school, but things stay together.

Rex, just hold the drawing of your setup in front of the mirror, than you see what mine is.
The idea of stepping down the spacer creating a lip to hold the brake stay/bushing in position is a solid way to do it. The flange of the stay bushing will be facing out ward towards the rocker, but for alignment the brake stay's position is up against the factory seal spacer, in fact for the final alignment step of it all that factory bushing might need to be shaved a little, or shimmed out away some. The location on the spacer step will solve that issue.
3 1/2 hours on the drill press and not even half way yet, and a hard day today, so maybe tomorrow I will get more done.
Hope all have a good night.

A 17mm fine thread would be around 150 ft/lbs.

So it did take another 3 1/2 hours or so to get the 5/8 " holed drilled, but the drill bit does not even looked used, okay some people can tell you it was used.
I was wondering about that torque setting, thank you Rex and Larry.
Help me understand why the Brake Stay bushing can not ride on the axle.
How do I keep the brake stay in alignment, the inner side rides up against the factory bearing seal spacer, right now all says that is dead on the mark, and the outter side of the brake stay is help by the larger dia. spacer that is between the rocker and the brake stay.
I ask because I made the brake stay with 3/8" clearance around the bushing hole, that is is if it was 3/4" OD.
Now, well if I go 7/8" OD on the stay bushing, we have a heavy 1/4" material left, if I go to the 1" hole we have only 3/16" of material around the bottom/sides of the hole. With this being 3/8" thick steel would this 3/16" be enough material around the bushing hole for the brake Stay ?
I thought I had the step spacer ordered, but in the end I have to order 5 of them minimum, and at 36.00 each, I had to pass on it, but most of the other hardware is on the way here.
I ask this because, if a steel spacer is riding the axle and the brake stay bushing rides the spacer, axle still gets wear from steel spacer. My mind says it would be more wear than that of the brake stay bushing riding on the axle.
I do pray this 3/4" hole drill's much easier than the past holes, a I am getting a bit worn out with it.
I hear you about the step spacer, a very solid idea, Bammmm! just hit me upside the head......The overall distance the spacer covers the axle is side to side strength, plus the step design gives side strength in holding position. This is far more than the 3/8" wide brake stay would cover. Yes it would have side support, but just not the same overall axle support. I am good, I see why and how it is better than the other way. I am sure each way works, just one is a better method than the other. I will spend more time trying to find my step spacer material today.
Thank you all and have a great day, Hump day it is, in enjoy it my friends.
