I have a sewing machine motor all riged up on the wood etc. (found some great info from you guys thanks a lot)Now I need some help the motor I have has a huge end on it and was looking for ideas on what to use to hold the arrow on the motor. This is the motor I have. No foot peddle used a dimmer switch.

You can take off the pulley and then use surgical tubing from the shaft(one the motor) to the nock. this is an earlier thread

How would you recommend taking that pulley off? I don't want to ruin the shaft of the motor. I know they make pullers but finding one that small might be tricky.
-
Does it have a key way or a allen key tightening nut on the side of the pulley.
-
I didn't look that close to it but will check when I get home. I just figured that is was part of the shaft and not a pulley that was pressed or keyed on. Thanks for the idea and I will let you know how I made out.

I picked up some rubber tubing from Lowes. I use zip strips the attach the tubing to the motor. I can't get my dimmer switch to adjust my motor speed.
-
is the dimmer between the wall plug and the motor?
-
IPC I got home and took a quick look and you were right, a small allen key and boom it was off. I don't know how i missed it but I want to thank you again for the push in the right direction.
-
Nice,show some pics when its finished.Good luck
-
Very interested to see some pics of your setup.
-
turn it on, get out your mill file, and grind it down to the right diameter .... Just a thought. It wont be pretty, but it just might work.
You could also try to put the pulley in a vise and hit the end of the shaft with a punch/mallet.
My guess is that for the fairly low power motor it is just press fit.

Here are some pictures, I have to make a few adjustments. I want to add a bored so I can put a ruler on it for marking distances out. Also I think I have to put another arrow guide on it to hold the arrow steady. I put a quick crest on with a sharpie to see how it worked and was impressed. Now I have to buy some arrows and paints, stains and lacquer oh boy.

I have the same motor. I took four or five rubber washers and superglued them together and then I used double sided tape to attach them to the pully. I like the rubber tube idea though. I had to use two supports for the arrow to turn on.

when i read the title to this post i thought you had a cholesterol problem, i was laughing real hard. "crestor" :) All sound like good ideas for a crester. Have fun! Nothin like custom painted arrows.

Spelling isn't my strong suit Nine lol
I found some old beaten up woods around the house I am going to stain them and then start the paint process. I see you a lot of you guys use hobby paint from the stores what brand do you guys use I am going to pick some up today while I am out and about.

you can get acrylic paints from walmart it a variety of colors.

Ok so I picked up some testors paint and tried out my new crester. I get an awful wobble with the arrows. No matter how I hold them down they wobble, I did manage to get three panted up as a test set. I don't think I have paint thinning down yet. Some of the paints went on thick and some to thin. The wobble didn't let me get the crisp lines but i will figure that out I hope. I still have to poly them again but this is what I got so far.

I found that I needed more in-line supports than I see in the photos above, Your arrow is gonna start vibrating and moving as it spins if you do not have support in several spots. If you can devise a fold over roller that surrounds the shaft and keeps it absolutely from bouncing, that could be a cool addition.
Keep the tubing section short and even try inverting some of the tubing over itself to double its thickness (thick end on arrow). If it is long, it will oscillate (?) and make the arrow bounce. The object is to keep the arrow spinning as straight as possible for getting nice straight lines.
Maybe glue in a support block just under the cresting area that comes up to within 1/2" of the shaft. If this extends out toward you, you can rest your hand on it while cresting and you can also tape a stencil on it so you can make all your arrows the same.
I don't like the foot driven rheostat on mine (my hardware is similar to yours). They seem to bump up the speed really quickly (it is too slow, too slow, WHIZ ! ). Faster is not better.

there is / was an insert available (maybe 3Rivers) to use instead of tubing, for the drive connection.
If you can get a chunk or rubber, a smaller sized hockey puck-like thing, and drill or cut a hole into one side to fit the motor shaft, and the other to fit the thickness (narrow edge) of your nocks, this would be less likely to ocsillate as it spins, keeping the arrow straighter.
