    Mine also only clicks one way, but the square drive pushes through so it can be used on either side (i.e. either way) - or have I misread the problem?

    Search for 'photography' - this comes up (amongst other things)

    My technician (secondary school D&T) bought a MAPP-oxygen torch with frame repairs in mind some years ago, but didn't have much success.

    Don't recall any efforts to weld with it, just brazing - I think he was trying to flood a lugged joint and found the flame to be too localized, and then discovered how expensive the oxygen was - he eventually resorted to bringing stuff into school and using methane-compressed air in the hearth

    I've had reasonable success at home (now retired) brazing up to 5/8 diameter and silver soldering up to 3/4" diameter steel tube for racks and bag supports using a (B&Q) GoSystem butane/propane torch at nominally 1450W. This needs several firebricks to reduce heat loss from the joint area, an excess of of flux due to the time involved, and much patience: 1/2" tube isn't a problem but larger diameters become increasingly marginal - I wouldn't attempt anything frame or fork related with it, but it's a useful addition to MIG + angle grinder (my welding is not neat - I don't practice enough)

    I did an welding course organized by the LEA some decades ago to cover the H&S aspect for welding in school (3 of us welding as required, none of us had any formal training) - might be worth looking to see if this is an option - also ticks a few professional development / training boxes?

    (just re-read / properly read the original post: 'teacher' is not the same as 'D&T teacher' so you might have to ignore the last bit...)

    Forgive me for what is probably a really stupid question. But, I want to sort out some paint chips for this frame. ![](https://sslcache.se/818d507edc4c8a75c32a0514ddc0936f882dca8c/687474703a2f2f696d6167697a65722e696d616765736861636b2e75732f76322f363430783438307139302f3139312f3836746c2e6a7067) If I buy this: ![](https://sslcache.se/d9ab981419577b8920acd97559f178ceb22e1619/687474703a2f2f6563782e696d616765732d616d617a6f6e2e636f6d2f696d616765732f492f34315137567074645a714c2e6a7067) And mix it with some white, am I likely to get close to what I'm after?

    Try:

    Tick all the 'brand' boxes and click on 'show paint charts'

    I've ridden to my local* model shop in the past - the railway enthusiast that runs it was very helpful, bringing tins out into daylight for comparison with the frame.

    Hydragas? wonderful invention, there's a bloke lives near me specialises in fixing it.

    Hydropneumatic? Citroen?

    Predates Hydrolastic and Hydrogas which were largely developed by Alex Moulton and used by BMC / British Leyland in (amongst other things) that engineering masterpiece the Austin Allegro...

    Yeah could be that, I usually use it to test new cameras as its cheap. It worked well with my AE-1 though. It does have that dial yeah. I used it a couple of times but I'm not sure if it makes any difference if its displaying the same shutter speed on the meter. Unless it has more increments of hidden shutter speed?

    Aperture priority? You'd need to confirm this with someone who is an actual user, not a pensioner relying on failing memory...

    Am I right in thinking the OM20 has a manual dial to change the exposure by + 2 stops allowing you to expose for the highlights with the centre weighted meter?

    Perhaps try a red filter - arguably this should increase the contrast where sky and foliage are concerned and bring out the texture in masonry and stonework?
