For me, it is easier to address these lengths in those 32nd of an inch increments, as that is the way I order them. If you do a lot of work on machines, you are going to wind up having a variety of rivet lengths on hand to pick from. Remember from the diagram above, the rivet is to act like a clamp, we do not need or want to expand the body size of the rivet at all.Ĭommandment 3: Thou shalt use the correct length rivet for the job. Second, if you are too hard on the clinching process and you wind up expanding the body of the rivet a bit, you still are not putting later stress on the hole you drilled. First, it gives you a bit of wiggle room in case the drill moves a bit. I always drill my holes 9/64" when riveting ramps for a couple reasons. 1/8" rivets are the main diameter used on pinball machines. Backup washers are available on my site, on in bulk from Hanson RivetĬommandment 2: Thou shalt drill holes at least 1/64" oversize from the rivet you are using. A full thickness washer will possibly keep your ramp from sitting flat on the playfield. Thin washers are very important in places like ramp flaps, where the clearance against the playfield is tight. Rivet backup washers are usually half or more of the thickness of a standard washer. ![]() Now that we know a little more about the two main kinds of rivets out there, lets talk about a couple very important guidelines when using a semi-tubular rivet.Ĭommandment 1: Thou shalt use a backup washer any time you are clinching against plastic. Pop rivets have their place in the world, but we can do better on our pinball projects! Second, they expand the body of the rivet in a manner that could easily deform or crack your plastic parts. First, they are ugly and not-OEM looking. The problem with these rivets is two-fold. Once the head bottoms out in the rivet, the pin will snap off. You do not want to use pop rivets! Pop rivets work by pulling a pin with a bulbous head on it through the body of a tubular rivet. This is a solid body rivet with a smooth exposed top, and a hollow base that will be peened or rolled over to clinch it into place. What you are looking for is known as a "semi-tubular rivet". You need some special tools, and there is always a fear of doing damage to the nice, new parts you are trying to install.įirst, lets talk about rivets. Riveting has always been one of those pinball skills which many do not want to bother with. Riveting.this article will probably lean toward the literal sense of the word as opposed to the figurative version! ![]()
