There's been much discussion on the topic of which of the Pistol Splat variants have the strongest spring. There are so many different versions of this one blaster, it has become difficult for me to keep track of all of them. Replacing the spring, will make any of the variants on par with the "strongest" versions.

Here's the industrial spring (bottom) with the stock spring from a Blizzard variant (top). Ace Hardware #199. It is very similar in size, immensely stronger though.

The problem is that the spring has a smaller ID than the stock spring, so it doesn't fit over the stock spring rest. One could simply modify the stock spring rest to fit the spring, but I decided to make one entirely from scratch.

I measured the base of the spring rest. It's a 13/16" by 13/16" Square.

Posted Image

I marked a piece of hobby aluminum sheet (available at Ace) with the measurements. I also marked for a centered hole using diagonals.

Posted Image

I drilled a pilot hole in the center I marked.

Posted Image

I drilled a hole for a 1/4-20 Machine Screw using the pilot hole. The bit was a 7/32" one. Next, I tapped the hole with a 1/4-20" tapping bit.

Posted Image

I cut out the square with a precision hacksaw. I used a dremel at first, but the hacksaw is a lot easier to control and smoother.

Posted Image

Once it was cut out I used a bench grinder and some files to smooth out the square.

Posted Image

I made sure to test fit it in the shell as I went.

Posted Image

I cut some 1/4-20" Threaded rod as long as the stock spring rest. I didn't see any reason to make it shorter or longer. I then threaded a nut onto the rod and threaded the rod into the AL just bit.

Posted Image

I put everything back in the shell.

Posted Image

It primes just fine, with a harder draw of course. I've primed and fired it ~30 times (they were all dry fires, so I kept it to a minimum) and everything has held up fine. The one problem was that the rod came loosened out from the AL square over time since it hardly threads in. My solution was to dremel both sides of the shell behind the spring rest to make room for an additional nut. This keeps it together much better. If I have problems I with the nuts loosening still, I will switch to lock nuts or use thread locker to insure they stay in place.

If anyone is interested in buying one of these spring rests and/or an Ace #199 spring, PM me.

Doesn't this also make tension adjustable? Since you can adjust the placement of the nuts with spacers. I think for that reason, this would be a handy mod to do, even without the replacement spring.

If at first you don't succeed, add more epoxy.

Yes, that's another feature of this mod. I tried using two nuts on the front part of the rest so the spring wouldn't have as much room to move around. It seemed to make the blaster much harder to prime with just that one extra nut. I plan on doing some more testing.

A whole 0' so far- he said in the post that his tests were dry-fired, and do you see a barrel anywhere?

As I said I have not not alot of testes yet but I will be once I finish the mod.

Y-Brik is correct. I'm working to have it barrel modded within a few days, I'll let you guys know.

Wouldn't it be easier to try to find some washers to take up space to adjust the tension instead of using two nuts?

I don't know, the nut looks elegant enough to me. I always hated a stack of more than 3 washers as spacers for anything- always a pain to keep together. Using a nut means Venom has a 1-piece spring rest, not a spring rest and several washers.

I went back to Ace recently to get more of these springs. Turns out, the number is actually #199. When I purchased the first one, it was in the #101 bin for some reason. I confirmed the number by using the display board to match it:

I have yet to add a barrel to this thing and test it. That is still a top priority though.

Very cool. My black and Silver Pistol Splat PS-800 is ridiculously powerful. Of the few varieties that I have seen in person, the silver and black is the most powerful. I may have to do this mod on my red and yellow wipeout. thanks

How stable is the part behind the spring rest with the screw port? To me, it seems a bit concerning. Are there any noticeable stress fractures or whatnot around it?
