Challenge
All of those beautiful pieces of wood that don’t stack well can be quickly made into an tablet or smartphone stand.
Technique
My great lumberjack father provided some nice burl pieces. However, it was a struggle to find the right workshop tool to cut these irregular pieces. Finally, the obvious occurred; use a chain saw to cut the wood.
If they are small pieces, hold them down in a large vise like a Workmate.
Ideally, shape the parts on the uncut logs as the logs are the perfect vise.
It can be a little difficult to get the cuts the right depth and parallel to the base. Since it only takes 2 minutes to make one, make ten and pick the best. Note the void in some trees like above even avoids the need to drill a hole for a charging cable.
