Bevel the bowden tube ends

I use a very convenient tool to deburr/countersink/bevel the bowden tube ends. I found it by chance and it is very cheap. Now I use it everywhere (it also will deal with aluminium by the way).

There are two reasons to use it on bowden tube ends in my opinion :
  • it reduces friction of the filament on the tube square edges
  • it makes the tube softer so that it can be applied with progressive force against the PEEK for example, for a better seal
Before buying the tool I used my biggest drills, but it was much harder to do a proper job.




To remove the hairy results afterwards, quickly rotate a big philips screwdriver in the bevel

    Sorry I can't help... I found it by chance in a hardware shop, among a pile of unsorted cheap stuff. I paid a few euros if I remember. I can't help either with the name as I don't even know it in French :s

    Thanks Nic. I hope I'll get the chance to visit the surroundings of any Australian city at some time ;)
