Hi Ted

Thanks for the comment but yes for me itâ€™s a bit of bling but I was told once that one of the reason for holes and slots is two fold and why even hi performance road cars have them

1 it prevent pad glazing at high temps

2 also as the pad rubs and heats up to high temperature the pad material produces a hot layer of vapour that sits between th disc and pad surface and hole and slots allow this gas to escape so you have better pad contact

But you are right for me itâ€™s bling as with the twin disc front and to now in progress rear disc I think the bike braking is much improved

Also now Iâ€™ve got the Dresa rear swinger fitted and once the brakes are sorted, time to fettle the suspension a bit as I just love to improve things from standard

Maybe father Xmas will drop down the chimney I nice pair of JSS piggyback shocks and a race tec front end kit with springs and emulators and also a nice set of adjustable spring preload units

I guess that the engineeer in me

Best wishes Al

Loving the Solid Works shots mate, that looks great. In retrospect i did too many rows on Chewys but its all alearning curve and more info has come to light since I did them. In fact, just now!! ;D
I hadnt even considered the following : "with a second set of three that are pitched so the total pad area other than the outside and inside edges are covered and holes are only 6mm with plenty of space between holes to insure disc integrity". Like I say I copied a photo but, It'll be better next time.

Yours will look brilliant if you end up doing them like that. I've managed to get everything I need for the twin disc set up now so I'll be having a good read in the next couple of weeks and cast an eye. I'm a bit knackered until I get the pipes back from being 'Middle Class' Ceracote'd and get my air box from the states, it's en route so looking forward to a box of 'shiny' coming.

Soon as they're on I can get it in the hall under the stairs for the winter and get the 550 on the ramp.

I feel for you mate re your back, that sounds a right arse hat of a scenario to be in. Bad backs are utter misery, I feel for you mate. At least you're going straight in and getting it sorted, best way bud but thats going to knacker you for bit i shouldn't wonder? Does this mean more cottage printing while you're malingering until Christmas? ;) ;D

Stiff upper lip mate and go steady. Keep me posted on disc designs etc, they look spot on at the min, just the right amount of cool with function as well as form. They'll look wicked on spoked rims mate. Spot on.

Best of luck with it all Al and stay sharpe.

Cheers buddy

If you need any info feel free to just ask a I will see if I can help in any way

Now hopefully found a CNC guy that does not seem too expensive and he is like my printing business (vat free) so I am looking forward to seeing the parts for real

Trouble is my position at work as a principle manufacture engineer means my site responsibilities are huge so it donâ€™t leave me much â€œHomerâ€ time for this type of project even though I have access to a toolroom so sometimes itâ€™s just easier to bite the bullet and get made plus it supporting a local lad who is just starting out as a business and pay for it with my
3d printer business profit

Also as a plus side all he needs is my model file so no engineer drawing

Catch up soon

Best wishes Al
