Afternoon Gents 1973 Silver Shadow SRH16373. Solid rear discs. Does anyone know of an on-car disc machinist who's lathe fits onto the REAR hubs?. I had two blokes over here and both have giving me bad news- their adapters simply don't fit over the big hubs. I'm Bris based but would be open to a nice road trip to an interstate city. Certainly not looking forward to the horrid alternative.... | ||

A machinist friend of mine made an adapter for me, to allow the connection of an on-car disc skimmer to the hubs. It WAS hanging on the wall of my garage in Somerset, UK, but I can't find it now - a photograph might be helpful. It may be on a loan which has extended to permanence - I last used it about ten years ago. It's a substantial bit of steel so it's not easy to lose it. But it is possible. Alan D. | ||

Sorry Nick. Can't assist here, but will look forward to seeing if Alan posts an image of the adaptor, would be interesting to see. | ||

The oddly sized hubs dims are a damm nuisance with RR cars. Fortunately my local RR man has an adaptor to fit the mobile brake guys machine. Ask a RR specialist Note when facing discs on the car the wheel bearings must have no lash. The front is easy, just adjust to slight preload. But rears you can't. Light damaged on a parallel disc can be cleaned up with a flexible grinding pad , a light touch though. Also using the car with modern pads helps keep the disc clean. Safety note. Naturally one wants to spin the hub, be careful with fingers , chop lumps out. Done that. | ||

Hi Gents Alan- your adapter would be worth good money as no RR mech in Bris, Syd or Melb has an economical answer. Just did the ring-around. Seeing as it's a minor vibration on highway braking, I'm happy to leave it as is for now. | ||

Hi Bob, thanks for your advice- always welcome mate. | ||

""Can't assist here, but will look forward to seeing if Alan posts an image of the adaptor, would be interesting to see."" I've searched the garage and workshop - can't find the adapter. It may be on a forgotten "permanent loan", but ...... Alan D. | ||

I was right - "permanent loan". The chap who borrowed it has now bought a universal adapter which will take almost any type/size of wheelhub - 500GBP from the Swedish manufacturers. Here goes to try to post some pictures. You may be disappointed because (A) it's a bit rusty, and (B) it's a very simple bit of kit. This skimmer is bolted to the wheel ONLY and therefore the condition of the bearings is (almost??) immaterial, I think. The mechanism must be supported to stop the skimmer revolving instead of the hub/disk. The five big holes take the wheel studs, the four small holes are the interface to the machine. Alan D.   | ||

Hi Alan That's an excellent piece, would be a 5-minute job for the machinist- if only you were in Oz!. How much does it weigh?. Maybe we could work something out?. Nick | ||
| Nick Adlam Frequent User Username: crewes_control Post Number: 52 Registered: 12-2015 |
I was thinking of maybe hiring it from you?. | ||

Remember the adapter has to fit the skimming machine as well as the car, so you need to make sure they are the same brand etc. If you can borrow one of the adaptors from a local skimmer you may be able to get a machine shop to make you one which will match the skimming machine and make the other end fit your car. Or perhaps he has one which would have space on the rim to get a machine shop to drill holes to suit RR&Bs? | ||

Hi Paul One machinist showed me his lathe's adapters, including one that is universal (virtually any stud pattern) which can be mounted using bolts threaded into the 4 holes on Alan's adapter. A little unwieldly admittedly, but the only alternative I've been given is new discs- and we all know how much fun that is!. Of course, I would clean all mating surfaces so everything lines up nicely. | ||

Hi Nick, You always like something different and out there LOL Here are my thoughts, but please correct me if wrong or already attended to. I wouldn't be machining on the car. I would be removing the lot which would then give me opportunity to inspect all bearings and re pack or replace if sus. Just saying  | ||
| Alan Dibley Experienced User Username: alsdibley Post Number: 20 Registered: 10-2009 |
Nick, it weighs about 9lbs/4kg. But I look after four Shadows/Ts for me and my friends and occasional others, and every new Shadow in the group needs the rears skimmed, after the hydraulics have been sorted, so I am loath to let it out of UK. And the four driving holes are positioned to mate with the particular Swedish machine it was built for (I don't know the make - it is a few miles away from here). All(??) disk skimmers have adapter plates available to allow use on any hub, I think. ************************************* ""One machinist showed me his lathe's adapters, including one that is universal (virtually any stud pattern) which can be mounted using bolts threaded into the 4 holes on Alan's adapter."" ************************************* But if you have an adapter already, you don't need mine???

Hi Pat, the rears were pulled back in 2012 (13,000 miles ago) and the bearings were replaced and discs machined amongst many other things during a major recommissioning. The previous owner was good on maintenance but was a somewhat spirited driver and the disks have now slightly warped again- seems to be common with early Shadows. The fronts are still good. Just being fussy I guess, the brakes are quite smooth, but not perfect, especially when pulling up from the highway- with passengers too, of course!. Alan, that's fine- totally understand. A machinist who visited had an adapter that could bolt up to your adapter. Unwieldy, yes, but doable. | ||

Took a few photos of my adapters, but they are too big as usual and I'm mobile atm. Put them on FB for now just for ease. Hope they help. Pat, if time and cost is not an issue yes it would be best to change everything for new. https://m.facebook.com/BentleyWales/photos/a.1043805645655607.1073741830.137933226242858/1044499318919573/?type=3&source=54 https://m.facebook.com/photo.php?fbid=1044499288919576&id=137933226242858&set=a.1043805645655607.1073741830.137933226242858&source=54&refid=13 https://m.facebook.com/photo.php?fbid=1044497695586402&id=137933226242858&set=a.1043805645655607.1073741830.137933226242858&source=54 Hope that works. :/ | ||

Nick & Paul. Great feedback and images. Your right Nick, nothing worse than lumpy or shuddering brakes, quite embarrassing indeed. 13k is nothing for bearings of this size after a good re packing. Hope the skimming works mate. | ||

Paul, The "sliding spline drive" would be ideal for this machine as it will facilitate setting the machine up against the discs after fitting the adaptor to the disc. Nothing better than having a machine designed and made by professionals with the experience of what is needed to do the job and maximise productivity. | ||
| Paul Yorke Grand Master Username: paul_yorke Post Number: 1588 Registered: 6-2006 |
Hi David, The lathe attaches to the adaptor through the centre of the drive with a hand tightened set screen. It is flat lace to flat face and the Allen key fits in a hole to stop it slipping. Mine is a procut. Lots on youtube. The gyroscopic truing system would impress you I think. |
