ranger 1,750 #1 Posted February 3 (edited) Whilst looking for something else, I came across this in a draw in my garage. It follows the ‘Archimedian drill’ principle. As you slide the centre piece up and down, the ‘twisted bar’ oscillates to lap the valve and seat. The rubber sucker fits on the fixed end, whilst the other, (knurled) end piece, which you hold, is free to rotate. Brand name is ‘ Sykes - Pickavant’, Made in England.🇬🇧 Edited February 3 by ranger 10 1 Share this post Link to post Share on other sites
