The rails and log bed with log clamps are complete and after testing it by cutting another log I found some short comings with the clamps and my right blade guides.
Here is the new blade guide for the right side and it works much better and is smaller than old one.
The log clamps had some serious short comings as I had the uprights too close to where the left blade guides travel and unfortunately were in the way of blade guide for which I had to put a block between them and the log to give enough room. They would also bend slightly back. So made some new ones with low profiles and high profiles. They all slide in a type of T-slot and work great. Some have screws sticking through to add grip on the log.
The log clamp slides loosely on a 1/2 in threaded rod and uses friction to stay in place.
Now I just need to add a push handle and the water coolling for the blade.
