I just got my first glass tube and i plan on getting an ashcatcher for it. How do I tell if the joint is 14 or 18mm? Where do I measure?
stick a dime in the joint/ If it doesnt fit in you got a 14mm, if it goes in but gets stuck..18mm, and if the dime falls right through you most likely have a 29mm
couldnt have said it better myself. lol. your most likely not going to have a 29 tho... they are way less common than 14mm or 18.
^no, that is incorrect. You had me second guess myself so I tried the trick on my 18mm LW joint and the dime barely fit and I know for a 100% fact that joint is 18.8mm
