DIY Arrow Saw

[coonhound]

I made this saw about a year ago, at that time I used a Dremel for the motor.  I just upgraded to a motor I bought from Grainger, it is a nice improvement.  I've got a bit of an advantage over the average Joe with access to a machine shop and sheet metal shop.  It's kind of fun to have a one of a kind tool on your bench.

Nice looking saw.

That is a good looking saw .   I watched a hunting TV show and the tip of the week was cutting arrows. It was very informative and they went further then I had seen at my local shop.  They advised to cut both ends as the spine is measured from the center of the shaft from the manufacturer,  then they dropped it in water to see what side of the arrow floated & marked the arrow with a sharpie.  This told them where to fletch and put the finished tip insert as they wanted them lined up.  Would be cool to have the saw all set up and do your own , I think there are some critical steps there for accuracy that I have not taken advantage of.

Looks nice.  I have kicked around making one too.

What was your total cost on materials?

About $100, the motor was the major item at about $50.00.  It's a Dayton motor from Grainger however I found this one on E-bay, it's about $100 if you buy it directly from Grainger.  It's the same motor that Apple uses on their saws.

I can't quite tell how this saw works. Does the motor swing down or slide to cut the arrow? If yes, could you post a picture of the hinge point or slide? Or is all of the movement handled by the front bearing mount while keeping the aluminum angle in contact with the two bolt heads?

[coonhound]

There is no hinge point, you simple pivot the arrow onto the bearings and then rotate the arrow to achieve a square cut.  You adjust the angle with the bearings so that the blade slightly cuts through the 1st wall of the arrow.  The 2 bolt heads you mentioned are only there as a guide to keep the angle square when making adjustments to the rollers. This is typical of most saws except they have a shelf rather than a set of rollers.
