homebrew cresting machines

Lets see some pics  or plans for your cresting machines.

This is with a sewing machine motor and a dimmer switch i bought from Home Depot.  The rest is scrap plywood.

I don't have any pics. But a friend of mine made one out of a golfball washing machine. Kinda goofy looking but it works.

I use a 3/8 inch drill and a cardboard box.  Punch two holes in the box at the right height, chuck in the arrow and fire away.  It isn't perfect, but if you take your time, it works out nice.

I just finished making this one. I haven't even had a chance to try it out yet.

The motor is from a water bath at work. The pump housing cracked, but it comes as an assembly with the motor. I'm not sure how the speed will be (I couldn't figure out how to wire it with a dimmer, especially since it's a 220 volt motor). I figure if it's too fast, I'll be keeping my eyes out for an old sewing machine. But since this motor was free, I might as well give it a shot.

Been using this one for about 15 years with pretty good results.

Here's one I did a couple of years back....I plug the sewing machine motor into a router speed controller and can vary the rpms quite a bit...

They all look great let's see some more!

I have a sewing machine motor and dimmer switch.  Was always going to build one, but never did.  Now I mostly use carbons and wraps, so if anyone can use them to build one, shoot me a PM.  FOUND A HOME FOR IT!  THANKS

Here's I made and use. Made from a Rechargeable Screw Driver & Scrap Plywood with a Automotive Switch....The Paint was my son's idea..

I don't have any pictures but every one I have made look simular to all above.

One thing I found that works real well is to mount the motor to a couple feet of rain gutter with a V noch cut into a piece of foam/wood/metal.

I'm weird.I have crested hundreds of arrows by setting the shaft in the v blocks of my old Groves arrow straightener, setting the straightener arm down on the shaft and turning the shaft by hand.

Justin, great article in the last tbm! congrats.

I have a sewing machine motor to make a crester if anyone needs it, make me an offer.

thanks,

Cool stuff guys! I'm looking to do some cresting soon! Gotta build one first!  

[BowHuntingFool]

Kinda a dumb question     but I was looking at Sewing machine motors, I need one that spins Counter clockwise correct???

Here's a cresting machine I made. It has a d.c. motor that is adapted to the right rpm's for cresting and is powerd by a 230V~ a.c. to 5 V d.c. convertor.
I also made several templates for the arrows I paint.

Wow V-Archer, i love that set up.  i have been telling myself to make something like your drying rack and template for years.  Thanks for the picture.  Jack

GREAT Set up, V-Archer!!!!!!

I'm having a terrible time getting my motor control speed in check. I've tried 2 different switches, one is a ceiling fan motor control and one is a simple dimmer switch. All they do is act like an on/off switch?? Any suggestions??

The motor is a 1.3 amp and just a little beast, moves the arrow all over the plac and too fast to apply any paint!

BowHuntingFool,

As I mentioned in my post I use a d.c motor with adapted rpm speed. When using a.c motors you have to be careful with dimmers type of controls. Most of the times they are not able to control motor coils as these almost have no resistance. You can use a sewing machine motor with the original speed control paddle as alternative.
