First of all, I would like to thank all of those who visit our forum and help others with advice and offer their great tips and tricks. There have been two alternative ideas posted in regards to creating the hub flanges that I use on trikes and quads such as the DeltaWolf, Kyoto Cruiser, Street Fighter, Gladiator, and Lode Runner. One alternative to the machined disc is to cut the required flatbar or plate using the appropriate sized hole saw. The other alternative is to source out precision made washers of the appropriate size. Often these washers are called "fender washers", "dock washers", or "aircraft washers".
I would like to present another alternative to the machined discs that only requires the use of an angle grinder, and hand drill. This procedure takes about 2 hours for all four discs, and is very effective if you don't mind spending a little quality time with your angle grinder. Since the hub flanges required in the plans vary in size, I will not be posting measurements here, but the same procedure will work on all trikes that use the hub-axle system I have developed.
