I often just pick up a piece of round bar. We will look at some details as well as some suggestions from Hugh McDonald. Figure 14 These are commercial bottom fullers. They are marked by diameter, not radius. And although they all came from the same shop they all have different shank sizes.
Figure 15 These are top fullers. The handled one is hand made and the other is a commercial fuller. The hand made one is actually a better design, having a very thick section around the eye so it will not swell the eye when struck. Figure 17 These are typical power hammer fullers. The narrow wedge is used for isolating stock. The half round is used both as a fuller and turned upside down, as a flatter.
The large half rounds are common in power hammer work but take too much force to be hand struck. Figure 18 The wedge fuller is used to isolate stock and leave a surface perpendicular to the flat. Figure 19 The wedge is often used alone on all sides of a bar but it can only be used for shallow depressions or it will push stock into the groove on the far side.
For heavier double sided fullering you need top and bottom fullers. Top and bottom fullers are used together at the start of so many forging processes and when the smith had a striker and an apprentice it went like magic. The lone smith however, holding the metal between his legs while doing the same job can really make his eyes water. Calling his spouse, child or neighbor to, "hang onto that while I hit it," is often not helpful either.
In use it lies on edge along the anvil with the heated steel slipped at right angles between the legs. Hammer the top one down for even grooves on both sides of the work. The deluxe model mine has a short piece of heavy walled square tube that fits the hardie hole and is arc welded to the bottom leg so it sits there ready for use.
Figure 20 Make whole families of round and square ones of various sizes as you fancy. Figure 24 Click For detail Square, heavy wall tubing, called RHS here in Australia , of the appropriate size is great for hardie tools. It is easily tapered hot, quickly cut off and arc welded to the tool and is a lot less likely to damage your anvil than solid steel when driven hot into the hardie hole for a good fit. Many anvils have been broken this way.
Hugh McDonald Figure 21 For fullering large round stock or pipe it helps to have a curve in the fuller to help push the metal toward the center. Here the bar has been bent and the bottom has supporting spacers welded on to it. Note the side guides. These are not necessary but they help keep the top bar centered over the bottom for picky work.
The guides are made of pieces of angle iron and give this spring fuller a nice base as well as having a hardie hole tang. Also note the flattening of the loop. If the spring is to stiff you can flatten the stock. Updated with new photos. PF Guru, if of tool steel, is there a problem with die wear over time? Fullers tend to wear "in" not out so much. JOCK D Mike, there is always a new "kink" Brooks, shock rods are something hard possibly case hardened as well as chrome plated.
Never made anything out of one. PF Brooks, more like the springs notjustone Would shims on the top and a hammering surface to make the top basically supported like the bottom be beneficial? Rich Waugh More great and useful info.
Thanks, Jock! I've seen a lot unsupported on the bottom but I make them with spacers. Leo M Nice demo thanks Jock notjustone Thanks jock worry huge hammers don't fit my hands b eyes 'tis my first visit to a demo. Thanks for letting me in. Sleepingbear Great demo.

Shopping Cart. In metalworking , a fuller is a tool used to form metal when hot. The fuller has a rounded, either cylindrical or parabolic , nose, and may either have a handle an "top fuller" or a shank a "bottom fuller". The shank of the lower fuller allows the fuller to be inserted into the hardy hole of the anvil. The fuller is a forging tool, used to spread the metal. The fuller is placed against the metal stock, and then either the top fulleror the stock is struck with a hammer.
The rounded nose of the fuller spreads the metal more efficiently than the flat face of the hammer. Fullers and other hardy tools for metal forming and necking. There is a fairly good description from Wikipedia below: In metalworking , a fuller is a tool used to form metal when hot.
