The shaft prevents any radial movements of the components.ĭepending on the type of rivet, and its ability to support shear load, it can resist considerable forces. A permanently formed head at each end prevents the rivet from being removed from the hole. How do Rivets Work?Ī rivet is a mechanical fastener with a plane unthreaded shaft that’s inserted through holes to join two or more parts together. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft).įastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.īecause there is effectively a head on each end of an installed rivet, it can support tension loads. In other words, the pounding or pulling creates a new “head” on the tail end by smashing the “tail” material flatter, resulting in a rivet that is roughly a dumbbell shape. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. Rivets are used to join large structural members, small electronic assemblies, and just about any manner of part falling between these extremes. Otherwise, periodically check eBay or Etsy and be on the lookout for a totally unsalvageable case.A rivet is a permanent mechanical fastener consisting of a head at one end and a cylindrical stem at the other end (called the tail) which has the appearance of a metal pin. That said, do not delay when that notification email arrives because they are gone before you can even say "Singer Featherweight!". You can sign up for the in-stock notification and you will be notified via email as soon as one is available. Q: "Where can I get a clasp or latch for my case?"Ī: We carry the clasp part here, and the case latch/lock here, but they will show as out of stock until we have a fair number to make available for sale - about two or three times a year. A double-edged sword to be sure, but we wanted to address this question and answer so there would be no surprises as you proceed: With an increase in restoring original Featherweight cases, however (whether it be to an original style appearance with tolex or completely personalized with fabric such as the demonstration in this tutorial) demand for the part will increase while supply for vintage original case clasp and latch parts will decrease. The only way, as it currently stands, to obtain replacement parts is to wait until a case is totally unsalvageable and then offer the hardware parts as they come available. This is compounded due to the numerous clasp and lock styles that Singer incorporated into the design of the Featherweight 221 as well as the 222 case over the years. Regrettably, there is currently not a suitable replica that is an exact match and obtaining a manufacturer for the original design has proven very difficult. These particular vintage original parts only come available on our website a few times a year and they are gone within nano-seconds because of so many Featherweight owners wanting to replace the part. Vintage case clasps (and the locks they latch into) are a very scarce commodity in the Singer Featherweight world. We felt it was important to address this right at the beginning. IMPORTANT NOTE ABOUT CASE CLASPS AND LOCKS: The original case rivets were slightly smaller than the new split rivet's size of 1/2" and 10/16" depending on the case's thickness. She did this step in order for the new split rivets (or nuts and bolts) to fit properly.
