Once you are in a thread any further than page 1 (page 2 onwards), you can change the page number in your address bar;
to get to page 10 for here;
http://cs.finescale.com/fsm/modeling_subjects/f/29/t/147648.aspx?sort=ASC&pi240=2
just replace the 2 at the end of the address with 10;
http://cs.finescale.com/fsm/modeling_subjects/f/29/t/147648.aspx?sort=ASC&pi240=10
It’s not brilliant, but it does the job…
