Default Anglepoise 1227 Bridle?

Does anyone have one - the piece that attaches the arm to the shade? I'd be glad of photos and measurements so I can make one up. My grandfather fixed it with a piece of Meccano which hasn't done wonders for the balance of the thing. Anglepoise haven't got any of these parts for the old 1227s (confusingly, their current iteration is the 'original 1227'), but I imagined it was the kind of thing a lot of you have as work lights...

Here's a, not too brilliant, picture of my anglepoise with dimensions of the bridle

Thanks Keith!

I'm keen to imitate the original as closely as I can, so I'd be grateful for a side view too. Also, what are the fixings like? Are there just a couple of holes in the bridle, or does it have a shoulder or some other locating method?

I'll take more pictures later today and make measurements on the bridle.

Here are more pictures of the bridle plus measurements. There is a stud at each end to locate the lamp cover and a fibre washer between the stud and the cover.

The centre of the bridle is fixed to what I assume is a plastic block which is forced into the arm. I can't be sure of the dimensions as that would mean pulling it apart!

Let me know if you need any more measurements.

(I have some here which look the same. One thing to note is that the bridle has rotational freedom on the end of the square tube - I think a square block is pushed in, and the bridle is riveted on to a bit of tube which goes up a hole in the middle of that block and which rotates within it. The wire goes up the middle of the tube).

That's correct it does rotate on the end of the tube and it looks like it's riveted on.

Keith, that's really marvellous! Many thanks.

The only thing I can't see on your drawing is the thickness of the stock. I'm guessing it's 1/32" steel? I've had the hinge elements apart and they appear to be plated brass with BA threads. The Anglepoise website's timeline says that various materials were used for the arms depending on availability, so presumably the rest was subject to the same supply constraints and it could be something else.

The fixing I have is a brass threaded tube projecting from the arm, with a half nut clamping the Meccano onto it. Interestingly, it swivels an amount each way before hitting a stop, so perhaps it's an original alternative fixing method? If it's home-made, it seems a bit neat for a man about to use a piece of Meccano.

That's a nicer job than mine, which look riveted. Are you going to chain-drill and file those slots? Make it in ali - or plastic

I've just measured the thickness and it's 1.2mm. It's magnetic so must be steel.

Rotation is restricted to 90 degrees either side of vertical so there must be some form of stop associated with the joint.

Thank you again, Keith. It looks like the stop is part of that plug then. There's no key on my threaded piece, so I'll just have to snug it up tightly.

Mark - tempt me not! Yes, I'm planning to do it by hand and work it out, in steel for the springiness as it retains the shade. I could draw it up and look into laser cutting, I suppose, but the hinge pieces are uneven enough that I'm almost certain they were hand-finished so some idiosyncrasy is not a problem. Not that it matters at all, but it's nice to do a good job.

The slots follow the profile of the bridle, which is very gently wedge-shaped. It's going to be such a pain in the

I'll get some more pictures of the whole lamp in better light, but here's where it's at - lighting my desk! I found the switched lampholder in a box of bits, and the extra screwed cable guide helps to balance it properly. The only trouble is that there's no cable strain relief.

That's looking good.

I don't know what sort of bulb you're using but I found that an LED filament type bulb has about the right weight to allow it to be positioned in any position whereas a "normal" LED bulb was too heavy.

Here are some more pictures. I'm quite pleased with it, except the spraypaint has had quite poor adhesion. I've decided that's patina rather than trying to touch it up any more!

The problem I've had is with bulbs being too light! It appears to be OK now with a few different ones with the combination of lampholder pieces I have on the top.

The springs were in a bad way, but I used some 'Evapo Rust' for the first time and I was astonished at the results.

Looking very good, but I think it needs some grommets where the wire comes out of the side of the arms. (I got a pack of suitable ones from a car accessories shop a decade ago.)

Thanks G8UWM-MildMartin. I did wonder that, as the Model 90 I've repaired had these grommets. It seems a good idea. However, this one didn't have any when I started, so I wondered if they were a later addition. This one here, apparently 'original' doesn't have them. https://www.coolingandcooling.co.uk/...ise-desk-lamp/

My ones have grommets, or the remains of grommets, in those holes - both in the sides of the arms (like your one) or in the back of the arms (like the one in the link you gave). They're kind of oval, as you might expect - but a round grommet would probably deform to the right shape.
