had to make a set of new fixtures tonight to remove a valve nut from a soldered Benjamin
this nut was the tightest one I've come across and was also loctited by the look of it coupled with the fact it was in immaculate condition made it a difficult process
I made up two nylon 66 vice clamps that will spread the load and not mark the finish probably never use these again as they're only fit the transitional models but I think I'll make a set for c series and the Bengy 312/7 and 342/7
