My First Floor Loom!

Got lucky on FB and found a Dorset Floor Loom not too far away. Just got it home and unfolded it. Happy to report that the reeds from my 24" table loom fit in the reed holder for the floor loom, which is great because the reed that came with the loom has some wear and tear (and a mountain of dust). Any tips on unique ratchet/pawl systems on the breast beam/apron? This seems to work by pulling outwards/backwards on the handle, then moving the ratchet down to pick up a tooth, and lifting up to reel in the apron (hope I explained that right).

I've been using a table loom for about five years, so a lot of this will be new!
