    Pete, did you ever try Schnorr washers? They’re quite similar to a Belleville but they have serrations both sides.

    Colin, I sent an .stl file of your part to one of our chaps this morning and he’s 3D printed your part. Just so happens that I’m in work tomorrow so I’ll collect it and check it against your original. If it’s ok I’ll do the same modelling and a print of the other base plate. I’ll send the prints to you with your originals. The prints won’t have the bend in as our printer isn’t brilliant and it would affect the quality. However, after a score with a Stanley knife it’ll bend ok. The CAD models and the drawings will have the bend in and the drawing will also show the bend details. The .dxf file for laser cutting will be a flat pattern (no bend). Please check with your “engineer-in-laws” if a .dxf file is ok. If not, tell me what they need.

    I have just bolted my brake discs to some new, aluminium hubs and some of the spring washers have deformed as per the attached picture. I’m considering swapping to Schnorr washers as we use these at work, they cannot deform in this way and they still bite into the fastener head and part. Has anyone else experienced this deformation and changed the washer type?
  4. Adrian Saunders
    Karl, an excellent result for you too. It’s fine and also cheaper to just go and do it and it will of course fit. If anyone wants knock out a quantity of the plates though, the CAD solution wins as the go straight to a laser cutter and knock ‘em out by the however many. Also, my CAD work is free to a good home. What did you paint yours with?

    Oh chain drilling. It’s like having a miniature Bridgeport. The threads had failed in the nut and not on the bolt and the nut had reached the plain shank of the bolt! You can see the plain section showing through the washer in the 2’nd picture. I think that the wishbone repairs are different on my two and I know that I only measured the other (offside) when sizing the new bolts. Anyway, new bolt, washers and nut installed and all ok.

    Colin, pdf attached. Would you print this off at 1:1, cut it out and try it out on the light please. For whatever IT reason I can’t print it 1:1! I have checked the part against the image on the screen and it’s very close. Herald Internal Light Base-Late-1-2020_05_10.pdf

    Indeed. As far as I know they are “S” rated. Standard run of the mill bolts from CC as used generally all over the cars. Interestingly, offside ok and near side not. That’s what’s pointing me at the wishbone repairs.
  8. Adrian Saunders
    Hi Adrian, the repair has been facilitated by welding washers onto the wishbone to bolster/replace the original holes. So, as the clamping area has increased In length I’ve endeavoured to improve on the original design intent by ensuring that the unthreaded portion of the bolts is indeed the only area taking the load. I appreciate that the original design (intent) lasts for decades but it is technically flawed and as a mechanical engineer I like to make these improvements. For those not wishing to switch to trunnion-less uprights, the correct length bolts are a viable proposition to a bodged/original solution, not a bad option. I am still hoping that I have made a mistake with washer quantities and will be able to replace.
  9. Adrian Saunders
    What do you guys think about the thread stripping? Feasible?
  10. Adrian Saunders
    Picture as per PM Colin. If I match the outer profile, holes and the bend, the high point of the internal cutout switches hand, the high point on the part on the bottom is obscured/on the right. Is that correct?
  11. Adrian Saunders
    Excellent, another potential fix. Thanks Pete. I think that bearing in mind the assistance/advice that you guys give, I shall join the club even though my car is still not on the road. Is this year a Classic Le Mans year? Do the TSSC have Tertre Rouge again?
  12. Adrian Saunders
    No problem fella. I thought you were referring to Dave CC. The damper bolts are 7/16” UNF too so, as a starting point, I was tightening them to the same. That shouldn’t have been a problem but, it appears to be. However, as my wishbones have been repaired at the trunnions bolt holes (previous owner), I have employed longer bolts so that the unthreaded portion is at the bearing areas, added washers as applicable and the shortened the threaded portion to suit. I’m wondering now if I’ve got the washers wrong and the nut went solid on the unthreaded portion. This damaged the thread rather than torquing out and eventually trashed the nut and pulled all of its threads out, so it can’t turn back off the bolt.
  13. Adrian Saunders
    Good idea. You’ve inspired me. I don’t have a cutting disc so I’m going to chain drill along the nut, along the axis of the bolt. Then I’ll turn it 180 and do the same. Then chisel. I have some more bolts. Thank you.
  14. Adrian Saunders
    What you on about chap?
  15. Adrian Saunders
    Aaaaaagh! Expletive! So, torqued up the offside to 44 lbs/ft (same as damper bolt) but, on near side, thread has stripped at bolt and/or nut! Of course now it won’t undo and allow me to fit a new bolt too. But why strip anyway? Same torque as damper bolt. Anyone used a nut splitter on this fastener? There’s only an inch space in there.

    Hi Paul. Mine are red. I’ll get some numbers off them for you tomorrow.
  17. Adrian Saunders
    Do you have an endoscope and an iPhone?
  18. Adrian Saunders
    Colin, I think I’ve PMd you.
  19. Adrian Saunders
    Colin, do you need my address?
  20. Adrian Saunders
    Are there any firmer, shorter springs available that don’t need an adjustable seat on the damper? I remember some with a ferocious rate of 660 lb, they didn’t need adjustment.
  21. Adrian Saunders
    Right, springs are off and I’ve checked them. 12.5” free length, 7/16” wire diameter and, employing the “sit on the spring and get the wife to measure the compression” method, they are definitely no more than standard rate. The compression check didn’t go too well, I was wobbling too much. I’m going to do it again tomorrow with a plank secured at one end and nominally level, won’t be as wobbly. Thing is, I’ve got std front springs but the rear spring has a 3/4” lowering block underneath it so, if I’m not careful, I’ll be guiding Chinooks into landing. The only thing that we’ve seen going to and from Birmingham airport this week. I guess I need firmer/shorter front springs to level the car?
  22. Adrian Saunders
    Doug, so, my compressors are the double-claw variety which go around half the wire and certainly look secure. Unfortunately, they’re too big to fit in between the coils of my springs.
  23. Adrian Saunders
    Certainly will.
  24. Adrian Saunders
    They have been repaired. I fitted the pivot blocks tonight. I knocked an old bolt in from the wrong direction and then chased it out with the new one. All ok now.
  25. Adrian Saunders
    Doh! My claim to fame was having the only GT6 in B37. Please don’t tell me you have one. Or, are you the owner of a dark Herald? I saw it once in Asda’s car park.
