For repairing B & H projectors, this set of tools is one of the recomendations. https://www.ebay.co.uk/itm/Bell-Howe...-/232676445581 . However the set is in the USA and quite expensive with the postage. Is there a set that does the same in the UK? Do people just try and use what tools they have got and hope for the best?
Thanks.
Clyde – I have to admit I did suspect some people do use allen keys. There is just that risk of getting it wrong and ruining the shape on the screw, and then you're stuck!
Maurice – thanks for the link, could be the only real option as its cheaper at least on the cost and airmail postage.
I have not looked at a B & H in close detail myself for over 17 years to really see what's practical regarding these screws, as that's when I sold my last example, and on which I certainly did not attempt to take apart. I'm just attempting to see what the costings are involved, as well look for a suitable example (probably a 1500 series).

As Martin said above, using the wrong tool could completely ruin a grub screw. The Bell & Howells with the infamous worm gear were introduced in 1961, so some are now really getting "old in the tooth", so undoing a gear or similar these days means having the correct tool to do the job.
