Finding and sourcing lightweight weights and clamping mechanisms for 15mm rods
16 years old. Gear and prices may have changed since.
What the thread found
- Industrial metal supply shops stock precut round metal pieces in both steel and aluminum that can be drilled with center holes and fitted with set screws or clamping mechanisms.
- Tungsten carbide is approximately 40% denser than lead by volume and can be cut easily with wire cutting equipment, making it suitable for custom weight fabrication.
- Shaft collars in one-piece or two-piece configurations are effective for holding round components on round rods.
- McMaster-Carr and Reid Supply are established sources for set screws, shaft collars, and other clamping hardware in various sizes and materials including stainless steel.
- Shaft collar reducers and bushings can allow smaller diameter collars to fit on larger diameter rods when exact size matches are unavailable.
Depends on
- The discussion does not confirm actual weights of the proposed solutions.
- Tungsten carbide sourcing details beyond the mention of wire cutting capability are not provided.
- The specific weight range of 0.75 to 1.5 lbs was not fully satisfied by all suggested alternatives.
