![]() The Poly and fibre cases are not quite as hard wearing as flight cases, and are ideally suited to light and medium duty applications. Silk screen printing of company logos available if required.Ĭustom Interiors can also be partitioned and foam padded to offer maximum protection to delicate contents. This is dependant on size.Ĥ x Swivel castors or 2 x wheels on one end can be fitted to aid manoeuvrability. Lids can be fitted either hinged with padlocking drawbolt catches or removable with webbing straps and quick release buckles to retain. Surface mounted hardware includes: leather, steel or plastic handles, padlocking toggle catches and flat or ball zinc plated 3 way steel corners. Interiors can be foam lined/padded with various types and thicknesses of foam. A lot of things that you see daily and take for granted, just like rivets.there really is an art to all of it.Designed by Dragon Cases and manufactured at our partner, Nomad's manufacturing facility here in the UK, Our durable and water resistant poly transit cases are available with an attractive textured finish, in many colours, which also easily wipes clean.Ĭonstruction: Lid and box rims have folded overlapping seams, fastened with bifurcated split rivets and reinforced with an 8mm welded steel frame. When i was working, i had a huge notebook that i kept all of my "Standards" drawings, "rivet specs", "clinch nut specs", and so on. ![]() Most of your rivets are all made to the same specifications. If anyone is interested, you can normally find rivet specs from the manufacturer, or sign up to a place like IHS GlobalSpec and find a lot of specifications. Hopefully that explains things a little bit. 001/.002 less on the depth to insure that when you roll the rivet over that both pieces are tight together. Any more than that and you may end up with a loose rivet job. So using a 3/16" diameter ballnose, you want to touch off of your tool that you are going to cut a rivet seat into and go down. 011 oversize, so going with the ballnose endmill slightly undersize will work with taking into consideration the tolerances of your rivet head. 187, or 3/16" diameter, or if you can find a 13/64" or. Since you can't buy a cutter that size off of the shelf, and most endmills come in fractional sizes, your next closet size is. 192 diameter, which ideally would be your cutter diameter. Which multiplied by two, to get your diameter, you end up with a. In laying it out you have to use both thew diameter of the head, and the height of the rivet as shown in the pic below to figure your radius. Take for example a drilled rivet/semi tubular rivet from Hanson Rivets with the following specifications: But the drilled rivet IS a full radius unlike a solid rivet, so all you need to know is the radius you need, find the proper ballnose endmill, and go only as deep as the rivet head specifications. Or take the easy way out and use a cad program to figure the radius for you. You can either do that by using your math functions that you learned back in school for figuring out the diameter for the segment of a circle. ![]() To make a proper seat for the rivet, you have to know both the head diameter and the head depth, then figure out what the proper radius is for those two figures. ![]() Now for the "semi tubular", or "drilled rivet", the head is actually a full radius. For example if the rivet seat is too deep, and you have a series of rivets to do, you will either deform the part trying to get the rivet tight, or the two pieces that you are riveting together will not be tight and could possibly cause problems if it is a critical part being riveted together. Both depth and diameter are critical to one another as far as aesthetics, and also function. If you hold the diameter, you lose the depth. When a standard ballnose endmill is used, if you hold the depth, then you lose the diameter. This gives the rived heat a proper seat to set in to where it will not distort the head, or leave a ring around the head when bucking the rivet. A lot of people will use a ballnose endmill to make a seat for the Universal rivet, which at time works, but is not correct.įor a Universal Rivet with sizes of 1/16", 3/32", 1/8" and 3/16".they take an 1/8", 3/16" 1/4", and a 3/8" special ground cutter and the depths are. On your standard solid "universal rivet" the head actually has a very small flat to it, then an odd radius out from each side of the flat. The head of a standard rivet and the head of a drilled rivet are drastically different. Semi tubular rivets are most commonly called "drilled rivets" in which the name comes from the hole in one end. ![]()
