![]() ![]() To pull the mandrel head of the rivet up fully you will need to pump the handles a few times. Once the die is in contact with the rivet head, squeeze the rivet gun handles together. Sliding rivet mandrel up in to rivet gun die cavity With the rivet in place, slide the die cavity over the madrel until it hits the rivet head. Step 4 – Slide rivet gun die over mandrel In some cases if the hole is too tight, as the gun pulls the mandrel up it can cause the rivet pin to expand in the hole slightly and if there is no where for it to go, it exerts pressure on the hole itself and the material it’s wedged against simply splits. ![]() This is especially the case when dealing with thin fragile materials such as the Perspex we are using here. If the rivet pin is tight to fit in the hole you may need to enlarge it slightly using a bigger drill bit. Rivet pin inserted into hole in Perspex sheets With the hole now ready, select your rivet and insert the rivet pin in to the hole so that the mandrel is facing upwards as it’s the mandrel that slots up into the rivet gun die cavity allowing you to pull the rivet up tight. Hole drilled through Perspex sheets Step 3 – Insert rivet in hole Once through, remove the drill bit and clean around the hole. With the drill bit positioned, drill down through both objects, taking your time. You should also use a sharp drill bit and keep it well lubricated.ĭrilling hole for rivet through Perspex sheets Apply too much pressure or move the bit as you are drilling can easily crack materials such as these.Īdditionally, drill materials such as these at a slow spped and do not apply too much pressure. If you are drilling brittle materials such as the thin Perspex sheet we are using in this example, be very careful as you drill. Pop the 4mm drill bit in the chuck of your drill and position it in the exact spot you want to add the rivet. In this case we are using a 4mm rivet we need to drill a 4mm hole. Once lined up in the correct place, select the correct sized drill bit for the rivet you are using. you have drilled out an old rivet and need to replace it with a new one, line up the existing holes and move on to step 3 below. If you are joining two items together using a rivet but the holes already exist e.g. Perspex sheets aligned together ready for drilling The first job is to align the objects you are joining together at the point you want to join them and then drill what will be the rivet hole through both objects. How to use a rivet gun to joint to objects togetherįor the purposes of this project we are going to be using two scrap pieces of 2mm Perspex, but what ever items you need to fix together, the principles are exactly the same. The mandrel should fit fairly snugly inside. If you look at the cavity opening in the different dies you will notice that they are all slightly different sizes which allow for different thicknesses of mandrel.Įnsure that you are using the correct sized die for particular the rivet you are using. The spare pin dies are used for different size rivets. The different parts that make up a rivet gun are as follows:ĭepending on the make and model of rivet gun you have it may come with a selection of additional pin dies screwed in to one of the handles. The main parts that make up a rivet are as follows:ĭifferent parts of a rivet Parts of a rivet gun To understand fully how to use your rivet gun and rivets correctly it’s important that you first understand the different parts that make up each item. To find out exactly how to use a rivet gun to join two items together, read on below. ![]() Once the two surfaces are joined, the rivet pin or mandrel then breaks off leaving the rivet in place and fixing the two surfaces together. Rivet gun and selection of different size rivets The rivet gun pin die then slots over the pin or mandrel and when the handles are squeezed, pulls the pin through the rivet which then deforms forming a dome on the underside, joining the two surfaces together. ![]() Using a rivet gun involves drilling a hole through the two materials to be joined at the point you want to join them and inserting a rivet that has two parts the pin and the rivet. Pop rivets are ideal for joining aluminium or even thin sheet plastic such as Perspex. Pop riveting is a technique use to join thin pieces of sheet material such as metal, plastic and in some cases timber together where a strong joint is not required. ![]()
