I have revised my threaded tubes - which retain the usual thread for the C mount lens at the front.
Added is another internal thread at the rear to take a supplied bored out brass bush to simplify securing an enclosure to it - with only the head of the bush taking up space inside.
In addition there are now three grub screws around the forwards part of the tube to allow the camera to be 'steered' a little inside the tube to help centralise the crosshair rather than using shims.
The revised tubes are £34.

As you will have to wait a few days for me to retrieve the tap and buy the bushes I'll do them at £30 each for Boxing day orders.
To expedite matters and minimise PM's I'll leave my paypal account up for today. Please add 4% if not paying as a friend. - and you need to PM me your postal addies.
