Martin,
The focuser will actually be 0.96", a common size, though today only seen in cheap smaller scopes.
You will need to make yourself a DIY Cheshire to at least check the secondary's alignment. You can make one easily using the 0.96" barrel from one of the eyepieces, or some other plug like item, and following the inspiration of something from here:

Show us some pics of the scope and we'll be able to better help you
Mirko has a good idea of a pinhole collimation cap
You can use the barrel of an eyepiece, fit it to a piece of card with a heat glue gun, put a wee hole in the card in the centre of the barrel, and there you have a pinhole collimation cap!
Once you've finished, you can remove the barrel from the card, flick off and glue left on the barrel with a toothpick and replace it in the eyepiece. Easy.
