Rather than a raw product I purchase, burl cutoffs are a byproduct of cutting Cue Blanks, Call Blanks, Cut Blocks and other dimensional stock, or a slab trimmed from a cap that, for whatever reason, I do not consider suitable for selling as a slab. What I do produce sells quickly, so unfortunately, I do not always have them available. I do not cut burl caps solely to generate cutoffs. That said, if I have sufficient demand and can produce a good salable product, e.g. cut block, to generate cutoffs for orders, I will do so as time permits. If you'll let me know what quantity you would like, I'll do my best to meet all requests - in time. The usual $8/lb price for cutoffs is based on a current weight standard (at time I cut) and thus lower than a burl cap (priced based on supplier harvest weight) so that they will move quickly. While I recognize that the majority of people interested in cutoffs are looking for pieces with natural edge for hybrid casting, I do usually have some non-natural edge cutoffs available that are suitable for small turnings, pens, etc.
Alternatively, when I do not have cutoffs available, I usually have a supply of thin caps (generally less than 3" maximum thickness) suitable for casting projects that may very likely be - because you can cut as you choose to achieve maximum yield for your needs - more cost effective than cutoffs produced when I cut dimensional stock. I also offer the option of free strip cutting. Below are some of the many thin caps in stock suitable for cutting for casting projects. It is not all inclusive. Keep in mind that dimensions (particularly thickness) are maximums.
