Question for open track speargun build:
I am designing a gun around a 7.1 mm shaft, an open track gun, I simply copying a Riffe 120. I would like to have the option to also shoot a 7.5mm shaft with a slip tip. I’m not sure if this is a good idea or a bad one.
I am having a hard time figuring out what size router bit to use to cut the track. Also cannot find any sizes that are metric, I am wondering if i should just cut it larger than 7.5mm or is it best to make it as close as possible. A 5/16″ round bit would make a 7.9 mm track is there an accuracy effect if the track is larger than the shaft?
Mostly seeking any feedback you can spare on this topic, maybe I am over thinking this issue?
Thanks
