Just fitted some secondary adjusters to my 200PDS, I got them from a firm called 'WDS Components Ltd' and saw then on an SGL thread.

They are 8168-227 Thumb Screws and were at straight refit and all for £8 inc postage (arrived next day!)

Collimation took only 5 mins and was so easy? Why don't they fit them as standard instead of those annoying grub screws?

Put a photo in my gallery as it wouldn't upload on here

It wouldn't cost that much for manufacturers to replace the grubscrews with thumbscrews, yours look great by the way.

I remember Dave JW mentioning some knurled thumb screws from RS components.

I was in there yesterday and had a look, with the ones Dave suggested it required buying some socket head screws, which the knobs fitted onto. However I would have had to have bought a box of them at over £16.

So I found these, RS number 631-9085. They have a female M4 thread, so all I did was cut the top off some M4 screws and added a bit of Araldite to make sure they stayed put. They came in a pack of ten so I have some to sell on, but I haven't any screws. I'll have a look for some A2 stainless M4 threaded bar, that could be cut down to suit.

Let me know if any one would like a set. I'll work out a price to cover material costs.

OK, I now have 1.5 metres of M4 stainless threaded bar on the way. So plenty to make knobs from.

Cost price of materials and the VAT works out at £7.86 for a set of three.

This is the knob.
