These rings are designed to allow you to make custom sabots and display boards where the various sized rings accomodate a range of different sized round bases. Simple select the size of ring you need from the drop down. The ‘band’ on these rings is 4mm wide and they are available in 1.85mm and 3mm thickness … this product is for 1.85mm rings, if you need 3mm thick rings please check this product instead.
A small amount of ‘wiggle’ room has been added to the internal dimensions of the rings, for example the 25mm rings have an internal diameter of 25.5 which still provides a tight fit but allows for the odd piece of basing material on the edge of the base.
When gluing the rings to your board, we recommend using regular PVA white glue and using a q-tip (or tissue etc) to clean up any excess glue inside the ring … this will help your bases sit cleanly in the ring.
