Trying to make an ultimate sanding drum!

[fatguyslim]

Hey Guys, I am back again. After trying my luck with knurling on to my ali bar I realised that knurls don't work well for something that is 400mm long and spinning. So now am looking for other solutions. One is that I buy a half round file (which is 400mm long) or try something even more insane. The insane idea is to mill (or ask someone here to help me) and produce a long version of this BLACK AND DECKER 90546472 POWERFILE 13MM ARM + PAD FOR KA900 KA900E | eBay. Now I know a sanding belt spinning at that sort of length is definitely going to cause many issues but i am running out of ideas. Can someone please help me figure this out? Any thing at this point would be of great help. Cheers

u need to face the end off, then centre drill it. then put it between the chuck and a live centre in the tailstock.

That's exactly how I did it. Knurling is not the problem here it actually the knurls that are formed are not sharp enough to shave the bamboo off at low speed thats all
