Although Buehler, our saw manufacturer, has many options for chucks to hold samples when cutting, some samples simply do not fit. In these cases, we get creative with ways to mount samples in order to section them properly. The best method we have found is to attach the sample to a backing that conforms to your available chucks. In these images shown, we used a blank round mount and a small aluminum rod that we sectioned to use for this purpose. We use Buehler Crystalbond as the adhesive as it melts at low temperature and can be completely removed by reheating and cleaning with a bit of alcohol or acetone. If you don’t intend to reuse the backing you can use cyanoacrylate or another epoxy.
