A custom tamper starts with the basket it needs to fit. Identify the basket manufacturer and model, and share a physical sample if the profile is difficult to capture. Add a dimensioned drawing when available so the supplier can review the target fit.
Describe the base and handle
Specify the base diameter and profile, the working face and the edge treatment. For the handle, share the desired height, grip shape and finish. If the handle detaches, include the connection details and any parts it must fit.
Decide what to check on the sample
List the dimensions that need inspection and describe what acceptable fit, grip and appearance look like. If you only have a reference photo, mark what you want to keep and what you want to change. A marked-up reference gives the supplier enough context to ask focused questions before quoting.
