Throw the spring away, I just use electrical tape to hold all sets in. The spring often gets in the way against bulkheads, thus pushing the gun that much off of line. I have not used the spring, except for my swivel set, for the last 15 to 20 years.
It only takes about a foot of electrical tape to secure the set, pull it tight, stretch is your friend!

I disagree.
The spring makes the tool safe.
If you tape to the spring (I do this my self BTW), the spring can be rotated to adjust the aim of the set while you are working.
I only leave a spring off when it does interfere. I put one back on as soon as it is no longer an issue.
Duct tape makes a big difference..... makes it possible to operate the gun with just one hand.

There are a million "right" ways of doing these jobs. Try lots of different methods and do the one that works best for you.
safe? if you treat the rivet gun like the power tool it is there should be no safety issues. Eleven springless airplanes and counting.

Ok Ron, you are making me nervous. I most certainly would not want someone to get hurt. In the spirit of safety I decided to have some fun and see what kind of damage I could do by shooting a rivet set out of my Sioux 3X gun.
I stood about four feet back from my wheel barrow of ash firewood, with 50 psi set on the gun.
I loaded the -4 straight rivet set in the gun. No spring, no tape, the set firmly pressed back, the gun in a horizontal attitude.
With a bit of trepidation I pulled back on the trigger. The set shot out about two feet and dropped on the floor. hmmm
I then opened the door to the shop and with my thumb and forefinger holding the set in place I aimed the gun at an old Locust tree, about 15 feet from the door.
I pulled the trigger and held the set as long as my fingers could stand it, a couple of milli-seconds, and then let it go.
The set flew straight and true for about 8 feet.
Clearly I needed more pressure.
At 100 psi I repeated the Locust experiment a few times and 12 feet was as far as I could get the set to go. The tree is safe.
So there you have it. I think that it would be fun if more of you would try this experiment and see how far can you get it to go? Perhaps my technique is wrong?

I think you are missing the point Tom.
Instead of comparing it to a regular fire arm may I suggest you try this test.
- Lay the rivet gun (with a rivet set fully inserted but no retainer spring installed) on the edge of a work table with the set pointed off the edge of the table.
- Stand directly adjacent to the table, and in the line of fire of the rivet gun (like you might when you are actually working at the table). This would put some part of your body no farther than 6" from the end of the rivet set.
- Reach for the rivet gun and pull the trigger while it is still in the previous position on the table.
- Report back the result. (I.E., painful irritation of hip bone, leg muscle, crotch area, etc.).
I imagine in advance your response might be "don't lay a rivet gun on a table like that"
My response would be "that is why they are called accidents instead of on purposes"

Ok, I tried that, exactly as you described.
I started at 6" with cardboard, nothing. Then a series of body parts.
With anything over an inch away there is NO pain. If you get really close to the gun, for example with a spring on it, or tape, or nothing, then yes you will get hurt.
It is a dangerous tool up close, regardless of how the set is retained. On that I think we can agree.
Try your test, and report back with the result.

I was thinking of the alum. part it could hit and what would become of that. Plus I was kidding, I like doing that.

Rivet guns are dangerous? No.....bucking bars are the real killer in this equation. Drop one from two feet on a toe and see what happens!  Or how about drills? Heck, I've hurt myself more with a file than rivet gun. Personally, I only use the spring with the flush set while doing skins, any other set and its taped in and has never been an issue.
