Hi,

Is it the top shoe pivot that is (often) in the wrong position?

On the two I've had rectified it was the bottom hole. Not out by a lot, less than 1mm

Yes. As far as I am aware they are always consistently inboard of where they ought to be based upon the Indian cases I have & others that I have worked upon.

Besides the Jockeys Boxenstop rear brake set up, trimming the shoes or relocating the mispositioned hole there is a solution that I intend to prototype & would offer for sale if the test vindicates my firm belief in the idea. I am by trade a design engineer so believe the best process is to prove a product prior to release, but would sub £40 attract buyers of a non-bling product to extend the life of any OEM type brake shoes used with any case or front drum brake?

Any positive feedback could well accelerate the process, that is, kick my @rse into gear....

I would go for 1. I have 3 cases which are out. 1 uses a jockeys set up which is spot on. The 2nd one also has a jockeys set up but try as I might I can’t get it satisfactory. The 3rd one had me skimming the shoes to fit but will need it doing all over again when the shoes need replacing.

I’d have one too please although I’ve only got one sil case you never know when it’s needed in dealing with other clubmates engines

Go on then count me in for one, I got 3 Indian casings
all with crap rear brakes !!

Looks like theres a few arse kickers.... Im in!

Gulp!

Thank you for the positive feedback, the result being that I've committed (or I should be... ) & ordered some material to get things underway.

I'm putting the 'cart before the horse' in some senses, as I really ought to model this stuff up on SolidWorks or a 3D CAD first, but fag-packet sketches must do for now.

Because I don't want to over-egg the amount that the pivot position holes need to be adjusted to come right on the SIL cases, I really would appreciate a little more help. The first two SIL cases I grabbed & measured from bore to hole position (pivots if in place would do just as well) showed a variation of about 1.0 mm with the upper hole being 'inboard' What would be great is if anybody would verify that.

The designed product should allow for a variation of greater than 1.0 mm but it would be ridiculous to allow for, say, 2.0 + mm if that has never been the case (excuse the pun ). It's a bit 'swings & roundabouts' if setting is crude rather than fine.

Thanks again & TYIA

Sorry no blocks on the bench, my SIL casings are in bikes.
Gonna be a while til i have hubs off

WTNo1.... Is the prototype complete yet????

Was hoping for one to fit this week....

The material from which the key components will be manufactured, arrived on Friday afternoon. There are other proprietary items that need sourcing, but they should be relatively widely stocked & promptly available.

As soon as I have prototypes, there are considerations I hope to discuss with somebody I have in mind, concerning certain aspects relative to trading & the ownership of my design. Any discussion should be brief & not protract the release of the first small batch of kits. The fact that I intend to do things properly shows how serious I am, which, I hope you agree, would also be in the end users' best interest.

If this initial product works out as a sound engineering solution to a particular problem, there will be other products to follow with similar intentions.

Please bear with me & I will do my best to supply my design in an actual form rather than just the virtual, as it is now. It is also my intention to have any manufacturing of all of any future products carried out in the UK where possible. There are many good reasons for doing so, one of them being that we may all feel perhaps a tad more pride in our nation's manufacturing capabilities for once.....

Keep at it.... Is eagerly awaited!!

You are a beaut

It would be extremely useful if somebody would have confirmed the amount that the top pivot point was machined out to the norm. However, I have a fully built race engine under the bench that I will pull the hub off tomorrow to give myself another guesstimate. That SIL case will then become the mule for the test to get the prototype kit under way.....
