I often have students planning to "make" a lot of the tools needed for making bamboo rods. Sure, there are a few things you can make but planing forms, indicator bases, measuring standards and the like are available from some good guys like Chet at Bellinger, Jeff Wagner, Dave
LeClair and others. They are properly constructed, well made and built by and for bamboo rodmakers. Do yourself a favour and buy the right tool and focus on making a better rod, it's tough enough .
