Thackery/Thackray/ Thackerey) Washers

paul wilks · Post by **paul wilks** » Fri May 18, 2007 8:51 pm

I have scoured the Internet and emailed several nut/bolt and washer suppliers for 1/4" Thackery/Thackray/ Thackerey(?) Washers to fit behind the rear wheel cylinders of my Javelin all to no avail. I have also contacted local engineering firms and garages specialising in old cars. So far only one garage person knew what I was talking about and he couldn't find any in his bits and pieces drawer! Incidentally he used to live in Marple round the corner from Roy Braddock and in the same road as our former tech info officer Ian Dearie!! Small world..... but he still couldn't help me!

Has anyone got a source of supply please? It's all I need for my rear brakes!

Thanks

Paul

I did a search with Google for Thackray washers and came up with Ford Sidevalve club supply.
interesting if you add 'girling' to the search, jowetttalk is top of the list!

Hi Paul,

I have used Nylock nuts here, which seem to work. Let me know if you have difficulty in finding supplies, as I am sure our local supplier has some and I could pop some in the post for you.

I am not sure if Jowetts had access to nyloc nuts when building our cars, as there are a couple of instances where they would seem more appropriate, such as in place of the symonds nuts used on the fan supports.

There are also some folks who have suggested using nylock nuts on the layrub couplings. However, this seems a step too far for me, as the thought of a propshaft coming loose at speed is too frightening!

All the best, perhaps we shall meet at the National?

David

David. Thanks. It looks like you could again help me with my numerous Javelin problems.

Yes, I would be grateful if you could purchase say 8 Thackray washers for me. I just can't get any here. I will also be using Nyloc nuts (as suggested by Mike on our latest web discussion). Rather than post them to me, could you bring them with you to NJC at Walton please? I will definitely be there. I am one of the marshals!

Thanks

Paul

The point of the Thakray washers was to provide enough grip on the plate to allow it to move with any imperfection in flatness of either the backplate or brake cylinder plate. Nylock nuts do not allow that movement, so if you do not fit the proper washers you need to leave a gap for movement. This might cause ingress of water/muck.
This is probably not something to loose sleep over and should not stop the car getting on the road.
I use Nylock nuts in lots of places; including the prop shaft and put some threadlock on as well. This keeps the threads clean from rust, and makes them easy to remove (no split pins), which was an important factor in the time constraints of rallying.

Sorry David. In my haste to reply to your last message I asked you if you could purchase 8 Thackray washers for me and only now realise that you offered to get some Nyloc nuts for me!

I have managed to purchase a pack of Nyloc nuts, thanks. Itâ€™s the Thackray washers I am having a problem sourcing.

Thanks anyway.

See at NJC

Hi Paul,
I called in at Povoas in Stretford today and the guy there knew what I wanted, Thackray washers, but was unable to supply any. I have always gone down the road of bolting the cylinders tight on the back plate and my brakes have always shown greater efficiency than modern ones on the rolling road.
With regard to David's point about the propshaft, I, like Drummond, use nylocs on the layrubs. They have removed all vibration from the transmission and are a lot easier to fit that twelve castle nuts and split pins. I can supply them to anyone who wants a dozen.
Are the Symonds nuts at the top or bottom of the fan supports ? I have always known the ones at the bottom as Oddie nuts.Or are they just the same thing ?

Thanks Ted. I have my Thackray washers so I can get on with fixing my blessed rear brakes!
Incidentally, I think the parts book appears to be wrong i.e. it shows the nearside backplate with the leading shoe at the 'bottom' and the trailing shoe at the 'top'. The website has a far better view, admittedly of the offside, showing the leading shoe at the â€˜topâ€™ and the trailing shoe at the â€˜bottomâ€™. I understand the nearside should be a mirror image of the offside so both leading shoes should be at the 'top' and trailing shoes at the 'bottom'. I hope this is correct!

See you at NJD.

G'dday From The Sunny But Windy South,

Dear Paul,

The burning question - did you get the car to the National Jowett Rally? If so, does it stop OK?

Instead of Thackray washers a rubber roofing screw washer can be substituted if used with a flat washer between it and the Nyloc (Simmons) nut.

Oddie nuts are of a self locking type and, looking at them from above appear to have claws that engage with the male (sex rears its head again!) thread, thereby imposing a degree of resistance to coming loose. A good example of an Oddie nut is the one at the top of the swivel pin of the non-rubber suspension system.

Kind regards,

Mike Allfrey.

Sorry to disappoint, Mike, but I didnâ€™t get her to the rally butâ€¦â€¦â€¦â€¦ I did attend and I got hold of a couple of dust covers that fit behind the backplates and are fixed to the wheel cylinders. Mine were missing! I only discovered how important they are when talking to Jack Mitchell on the Saturday afternoon. Nigel Morley located a couple of spares at home which he brought to the Sunday dinner.
In addition I have loads of Thackeray washers thanks to David Morris who located a supplier.
Renewed with new enthusiasm, on Bank Holiday Monday I fitted the rear brakes and the hubs (wasnâ€™t quite a twenty minute job, Drummond, but didnâ€™t take much longer!) Itâ€™s easier when you have had good advice and you (more or less) understand what you are supposed to be doing! I am now in the process of replacing the rear hose and filling with brake fluid when it stops flipping rainingâ€¦and itâ€™s nearly June! I blame global warming.
I have had loads of help and advice and I know I have been a right pain but thanks again to everyone for all your help.

It is appreciated and Iâ€™ll let you know when I get the brakes working and get the car through an MOT.

Incidentally Ted, what size are those Nyloc nuts on the prop shaft? Are they 1/2" BSF?

Thanks

Paul

TedAllen · Post by **TedAllen** » Wed May 30, 2007 11:51 pm

Hi Paul
Yes, the transmission nuts are Half inch BSF. Povoas has about 2000 in stock so if you want I can get some for you. Call in if you are up my end of the M56. I'm only 30 mins away. My phone no. is in the mem list
Regards
Ted

Thanks Ted. Could you order some for me please? Enough for propshaft x 2, please.

I'll be in touch and I'm looking forward to seeing your splendid Javelin!

All the best

Paul

Hi Paul
Will nip to Povoas on Monday and get a couple of dozen.
You need 12, of course, for the three layrubs and I would recommend an extra 4 as back up if you need to take the engine and box out at some future date.
My javelin not so splendid at moment, front n/s wing off for painting, engine resting loosely in chassis, bumpers and overriders away for chroming and not much trim left in due to new headlining being made.Also covered in cat prints and scratches. Fortunately two-pack paint so fairly durable. Just planted some Coleus Cananis in pots. Known as the ' Pee-off plant' they are said to repel pussies. Hope for the best !!! Classic car show this weekend at Tatton Park. Got the Renault F6C entered. No chance of a prize but a way of getting in free with a base to put all those autojumble goodies.
Ted

When this matter first came up I popped into Povoas, my local engineer suppliers to see if he had Thackray washers. When he was unable to supply them I felt rather smug and taunted Geoff about me beating him at last over the supply of an item.
I should have known better !
I went today to stock up on other things and found, to my dismay, that he had risen to the challenge and had found a box, looking about 70 years old, of Thackray washers. All right, they were 7/16 and slightly rusted but they were still the genuine article !
I picked up my goods, paid my bill and slunk away with my tail between my legs. Got to think of something else to challenge him with now.
Paul, I have your nylocs, although at great personal humiliation.
Ted
