Help needed - Crayford focuser
Guys,
picture the scene - no viewing for weeks and weeks, lug the 10" up to dark skies, too exhausted the first night to set up, second night aligned the finderscope beautifully, unpacked the as yet untried new (secondhand) pentax 7mm and all go for viewing Saturn and Orion nebula.
Then....focuser knob just turned round and round without moving the cradle in and out.
There's two screws on the side - I assume one is tension and one is locking. I tried hand tightening these without any change.
There doesn't appear to be any ratchet visible. Could something have dropped out, do I need to just tighten the screws more, am I just a dimwit????
Needless to say I'd spent the day painting, it was dark and cold and I just put my tail between my legs, packed up the scope and went inside for a beer.
thanks guys

PS - Oh, it's a Bintel crayford
