Hi Mary Ann, It seems that you’re having a problem with either your block assembly or your blade holder assembly. I would have your microtome serviced, it may be the block clamp isn’t tight enough or you have knicks on your blade holder. If you’re block clamp is ok, I would lean more on the blade holder needing to be repaired or replaced. The older blade holder assemblies cost more, as they were fabricated to last longer before giving issues with microtomy. The newer microtome assemblies can easily knick and give thick and thin sections, and in this case giving 1 good section, followed by a section that is chunking out.
Hope this helps!
