Cal....your local hobby supplier of K&S tube will also have the K&S tube benders & cutter...well worth the cost in terms of savings in crumpled tube bends = the scrap box
The first image are the 1/8"& 5/32" tube benders & the cutter, the second image ......clean smooth 90 degree bends with minimal thinning....& the third image

yes a crumpled 5/32" bend.......prior to the tube benders

and the last is 180 degrees in 5/32"brass...........Derek
PS....even with expensive tube cutters you can have problems.....

with the clearance between the hole in the cutting wheel and the pin that it rotates on....it can lay over and as you attempt to rotatate the cutter, the wheel wants to cut a spiral thread.......
If this happens....try filing a very light mark on the OD of the tube & place the wheel in this mark when comencing the rotation.......it can help
