I'm wanting to convert my railgun to a roller, but I'm not clear in my mind how it will all work. For simple numbers sake, let's say the barrel is 40" long. Leaving space enough for a reel, I figure the longest band stretch I could get is 40" on top, plus 30" beneath, equals 70" total. Dividing 70" by 3.5 (max stretch factor) yields 20" bands (right and left.)
To load the gun, my guess is that I start with the bottom portion of the bands slack against the muzzle -- then load from the top of the gun as if it were a "normal" railgun -- then turn the gun upside down and somehow grab the cord between the right and left bands (that is now stretched tight against the muzzle) and pull it back to the fully loaded position. Does that sound about right?
Will I need to wrap the shooting line any special way? BTW my gun (Aimrite) has a side release for the shooting line - and remember I use a reel, if that matters.
Oh, and is it okay to continue to use notched spearshafts, or will I need to get fin tabbed shafts? With a notched shaft, I'm wondering whether when the gun is fired and the wishbone stops tight against the muzzle guard (or whatever it's called) will that tweak the travel of the spear shaft slightly as the wishbone slides out from the spear notch? I think that would not be a concern with a tabbed shaft. Am I overthinking this?
Thanks in advance for your insights and taking time to explain to me.
