Thread: roughing up tubes

Nar, too much work for this little black duck.

I do it on the mandrel; slip 3 tubes on at a time, using the tailstock to hold the last in position, start the lathe, a quick wipe from one end to the other and back again with some 320 or 400grit and then... Next!

I put my blanks on a piece of 4mm dowell that is glued into the end of a dud blank then I let my belt sander do the rest it spins the tube on the dowell and sands the whole surface in about 5 seconds.

i just hold mine and use a dremmel with a sanding drum. Gonna have to try the lathe thing.

I don't do that does it help much??

Hi Toni, supposedly gives better adhesion in the long run,
sometimes I don't worry, or should that be forget.

Hi skew, I thought about the mandrel, but as I only had
ten tubes, well 3 x 3 = 9 So one left over, well thats my excuse.

Hi Brett, I suppose I could have turned the sander on, but if you
saw my shed you would realise no way of finding tubes once they
rocket of the sander. Anyway I'm flat out finding them five
minutes after I put them down somewhere.

I'm with Skew, I use the mandrel - easy as.

I didn't do it when I first started and maybe that was the reason that some of the tubes failed (I've been blaming CA all this time, maybe a combination of both)

I think it is especially important when the tubes are tarnished (I have had tanished tubes in brand new kits) and as Skew says, it doesn't take long and I think the results are well worth it.

My notion is all nail punches with knurled handles were made for the job of holding and hand sanding tubes,works for me.
