So lanyard tubing......
It occupies too much of my time.
I would hope that I drill an 8mm hole and with only a little bit of effort get an 8mm bit of tubing in place. If it's a tight squeeze, thin tubing collapses and deforms where solid bar can be encouraged through. I have got decent drill bits so my holes are the right size.
Material like brass is a bit more precise than some of the stainless I've got hold of.
How do folks deal with it or what am I doing wrong?
Giving the tubing a bit of a rub round with sandpaper can work but not always ok to get it even and without going too far to then get gaps and also parallel.
Sometimes I'll give the drilled hole a spin with some sandpaper to open it up a touch but even that is a bit hit and miss.
I would like some precision!!
I'm tempted to buy some drill bits 00.1mm bigger.
Or should I get the metal lathe up and running to thin sections of tubing down?
It really shouldn't be as hard as it can be!
