The double convex and plano concave come as a matched set as they're made of glass with differing refractive indexes. Some of the later replacements (made by Copyground in High Wycombe incidentally who are now out of business........) were cememted together because........ lets just say that it suited his needs with the glass he was using which gave a corrected figure.............. BUT, you could try to use a second hand double convex and having said that, it COULD be your lucky day because as I said above, generally, it's always the outer that breaks when the cack handed clown drop them and I have a couple of the inner double convexes that you can try. But in order to save having to explain how you do it correctly and optically, you'll have to send me your OG housing and when I'm in the mood, I'll see if either of those I have will mate up correctly with what you've got.

Not saying that it WILL work but it has been known to and it'll save you the £160+ for a new lens set

I'd just try a hat shop or one of these hobby shops. The felkt we used was, as I remember it, just the sort, off the roll, that was used for billiard tables. Certainly it was the same colour. I used to use a rounded stick to keep the stuff in place while inserting the draws

You have answered by problem.
I was trying to source a dense industrial type felt which I obtained a sample of.
I tried to compress it but yes I can see it is not the correct material.
I will retry again with a much thinner and less dense cloth.
Thanks for the information and may I add that I find your many articles really informative.
Did you glue the material in place or rely on the recess to retain it when inserting the tube?
Thanks for the prompt reply.

Just used the recess in the packing collar as I remember now. I have to say that I did a couple recently and had forgotten how twiddly it was. I was all fingers and thumbs but once you've done it a hundred times, even ?? years ago, it all comes back. And thanks for your kind comments
