For those of you unfamiliar with the Nelspot, it was the first paintball gun, originally made to mark trees.  Since I've gotten into pump and pistol play, I've always wanted a Nelspot.  It's a historical fusion of my two favorite styles of play.  I had seen SOLEX's Nelspot on MCB, loved the look, and wanted to replicate it.  He did amazing work.  If I can get mine half as good as that, I'll be pleased.

I picked up this specimen from Bacci on MCB.  Dan has EVERYTHING.  He only had back bottle Nelspots, but I wanted the in-grip 12 gram valve.  I bought one from another MCB member.  I also opted for an upgraded NOS Lapco anti-kink adjustable bolt, fluted hammer, cup seal, and #4P power tube along with a black pump handle (being a lefty, the bolt action is extremely difficult to operate effectively).  The pic at the top shows the Nelspot as it arrived.

Lapco internals and stock valve:


With the valve installed:


Date of manufacture: Nov 13, 1987, older than me, (it's a mutt Nelspot, but the date fits with the design variations, so it's close enough):



It was in fair shape, given the age (nearly 23 years old).  The paint was chipped, scratched, and rusty in many parts.  The insides of both tubes were rusty as well.






I started by using chemical stripper on the body and grip assembly.  It worked well on the body, but not so much on the grip.

After stripping:





So far I've only gotten the body sanded (and only partially at that).  After 100 grit and some 240 grit this is what I have:



And my home-brew hone (drill in a vice with a dowel rod and steel wool):


Surprisingly cleaned up the insides pretty well.  Still some deep pitting from rust, but nothing major.  It is very smooth.


I also cleaned up the pump handle screw.  It was very rusty and heavily pitted.  Chucked it in a drill and too sand paper followed by steel wool to it.

Before:


After:



Updates will come in spurts since I'm back to college.  I'll only be home once every so many weekends to do work on it.  I'm planning to sand all exposed surfaces to bare metal, polish them, then wax them to protect the shine.  Going for a black and silver scheme accented by some dark wood grips which I will custom make.



All pictures taken with my Droid X.  Pretty decent camera for a phone, huh?

very cool! 

If you need a polishing wheel I can probably do the final step for you pre-wax.  My brothers studio has all that stuff.  No charge or anything, you'll already have done the hard work by then.  LMK.

LOL.  Thanks.  I was surprised that it actually worked pretty well.  There's still a few pits in the barrel, but to remove them is going to require taking out a good amount of material.  Hopefully they don't affect accuracy too much.  You can barely feel them with your finger.

very cool!

I'll keep that in mind.  Brad said his dad has a bench grinder with a buffing wheel.  I think I'll try that first as I'd like to do as much of this myself as I can.

Cool man, I look forward to seeing the end product.

That's awesome man, especially at that velocity.  Looking forward to seeing the finished version!

Yeah, 260 starting. Settled in around 230-240 for the last 25 shots or so. Then dropped to 180 after about 45 shots. With the 5 inch barrel I'm stunned. But it does seem to be a pretty tight bore. I'm guessing around .680.

Hey! I have one of these now! But I'm not going to ruin the natural, 23 year old finish that it has. I'm just going to clean out the barrel and feed tube with some steel wool and oil the orings and call it a day.

Its the ultimate sleeper!
