Model Engineers Vice

My 3rd Vice and a vice which fulfills a specific brief, the brief is cutting small brass or alloy tubes etc and also square bar or tube etc, the amount of times I've needed this type of vice for such an occasion is numerous, many times I am cutting with a Dremel and cutting disc and I'm trying to hold it by hand and cutting, the cut is never straight etc so this vice should eliminate this problem.I've found with my previous 2 vices that it's best to run a die down the screw thread and tap the thread in the base, I picked the Taps and dies up on Amazon for not much layout and they have proved very effective, the threads cab be lubricated with something like 3 in 1 oil or similar.The adapter is fitted after screwing the screw into the base, its secured with a flat head 5mm Allen bolt and the adapter is secured to the sliding carriage with a 5mm Allen head bolt, a 5mm tap can be used for both applications as I've snapped the collar on the previous 2 vices but the bolts still screwed in ok
