Hi,
About ten hours for the first one, 8 or so for the second. This does not include time spent setting up the lathe and making some modifications. I did not keep a close time sheet.
The fixture could have handled a bigger log than the 15"x11.5' ones.
The Harbor Freight router replaced a Freud FT-2000e (almost new) that failed(speed control module) about half-way through the first column. The HF did the job.
