I may need to have some custom hardware fabricated. I have a source to have them made but wanted some feedback. I need to make small square cup style caster that has a taper on each side and has a slight curve forward. My thought was to make the leg as per the final shape including the caster, cut away as if I was applying the caster, essentially creating the stump with a thin shoulder. Apply some type of material? automotive bondo? epoxy? something that I can shape into the caster and then have it release from the stump. Any ideas on the process?
