Hi Spearfishing World Members,
I am embarking upon my first roller gun build and would like to share my progress as the project progresses.
After much research I decided upon building the gun to 95cm, which should be a great all-around gun for my purposes. It will use 2-stage loading to make it easier to load the band onto the tab. I will employ Chris Coates' data as much as possible for this build (14mm band, not 16mm and a 52" 9/32" shaft) as he has done all the research and I don't want to invent any new mistakes!
I will be using mostly Neptonics components, including the AR15 handle (which is removable from the base to facilitate travel, or just to change out grips) and Reef mechanism. For the roller I am going with the Meandros single roller system. I like the system because it can be upgraded to steel or ceramic roller bearings and is well built.
The stock is a 4-way teak laminate made from repurposed boards using the West System epoxy to hold it all together. I ripped it to a basic size and the wood has now aged for a couple of months, now ready for final planning to the finished dimensions of 1 3/8" wide by 1 3/4" deep.
In the pics I am also showing my router bit set. For this build I will be mostly using the 1/2" plunge bit for the handle and mechanism, the 1/4" plunge bit for the line release and the 3/8" round box bit for the open channel.
Once my buddy gets back from the Phillipines I will visit his shop to get the wood down to the proper dimensions and proceed with the build.
Stay tuned....!
