Hi ive treated myself to a new microbore pipebender its a silverline and does 6 8 and 10 mm pipe. I know how to use a pipebender as I have one for 15 and 22mm, Ive tried all afternoon to bend a 10mm pipe for under a radiator and the silverline bender just crushs the pipe its as if the profile isnt big enough I put it on the largest profile which is 10mm, Im sure im doing it right as its the same as my other pipe bender but I dont want to look an idiot if i take it back and say it doesnt work lol. It doesnt look very well made to be honest and was wondering if anyone else has any problems with these microbore benders
