I have attempted to build a diy jig out of a old drill , dermal and a small chop saw motor.
All speed control has been by a light dimmer switch.
First two were a semi fail , the last one works ok
The problem with all three have been wobble.
Wobble on the last jig is very slight but still is enough to make it impossible to get a perfectly straight line.
I have used bearings and other methods of attempting to remove any or all wobble from shaft.
I am about to give up on the Diy and just buy a factory jig.
I have never seen or operated a factory jig
So my question is this
Do they have any wobble or do they run perfectly smooth?
The 3 rivers jig is $200
I’d hate to buy it to find out it isn’t much better than what I have now.

Is the wobble coming from the jig or the arrow shafts? The spin rite crester works very well. There is no wobble coming from the jig itself. You will always have trouble getting perfect lines if your shafts aren’t perfectly straight.

The main reason for wobble, out side of arrow straightness, is a chuck / end driven arrow. That requires everything along the shaft be in alignment. Tiny misalignment at the chuck becomes much larger at 10, 15, 20 inches away. That is why I designed the Spinrite to be shaft driven.
This allows you to make lines like this

What Dan said. I know your pain from making a crester many years ago now. I never found a satisfactory chuck, the closest was the chuck for the Bohning Jr. crester but spares were had to come by. So I bought that crester but it wasn’t the answer either. Wood shafts have to be perfectly straight. So I bought the Phillips crester which is designed to keep the wobble out of the shaft. Yes it works but it is belt driven and the belts dried out to fast. So... I bought the Spinrite. Let’s say I am more than satisfied with it. Mine is at least 10 years old and works everytime. I followed Dan’s video and use it to spray paint my caps on my woods as well. By the way, his customer service is the best.

What I Did was take a quarter inch eye bolt and wrapped Butchers string around the eye until I got a good fit on the shaft. I drilled a hole in my workbench at the right height. No wobbles.

Dan: You didn't design the spinrite, You copied the Phillips Pro crester.

Bob, You have been spreading that lie for ten years and I have been letting it go. No more.
My inspiration was a Rightnour aluminum arrow straightener that I had been using by hand as crester for years. It still sits on my tool box where I used it.
I knew what I DIDN'T want in my design from REPAIRING and UPDATING Phillips cresters for other people. You call it a copy, yet it has more function than yours. Yes, a couple things are similar because after much testing (which I did myself instead making paying customers be my Beta testers) they were the way to go, but I can guarantee you the Phillips was the last thing I wanted to copy.

Going to order one of Dan's cresters. Heard nothing but great things about them and my grand daughter wants me to fancy up her arrows.
