Thanks AT members for all the idea to make an arrow saw using Harbor Freight saw. I noticed that the metal blade is not cutting smoothly even by rotating the shaft as I cut so I changed the metal blade with Apple Archery carbon blade but I cut it down to 2" diameter. I used the old metal blade as template and manually cut it with scissors then I installed it back to polished the edges to make it round. To cut smoothly and evenly I lowered the blade to hit the top of the shaft then manually rotate the shaft and worked around the diameter.
