I though about the tubes being too close, but thought I'd give it a try. I skipped a row between rows so it is really going to only hold 30 instead of 60. If (IF) I keep them in order by size , I'm hoping to be able to find what I am looking for. Coarse then there is the problem that when I add a new blade type/size, I have to rearrange every thing again.... Never a perfect solution. Well, except only use a couple different blades and not think I need so many different ones.......
