A New Pickup Winder Scratch Build!

Hey All,

I said I'd do this during this year's challenge so here it is, my new pickup winder scratch build! The premise was to use a solid design from Herb with a few twists. First thing to find was an enclosure. I thought about my old Star Trek lunch box but that was too small. One of the issues Herb had with his last winder was that the shaft pulley was too small @ 2" resulting in shaft speeds that were not usable. With a bigger enclosure I could fit a 3" or larger shaft pulley and at the local salvage yard, I found this! The guy behind the counter said "Gonna go home and fill er up?" I said "yep" but not with what he was thinking.

Hey All,

So with helper Luke, we set off on this grand adventure today. I have a Sears sewing machine motor off eBay, a 3" pulley from Home Depot, a Harbor Freight router speed controller, bearings, set screw collars, screws, 3/8" steel rod and other assorted stuff stuff from the local hardware store. The motor is a tight fit. I drilled a hole in the bottom of the can and mocked up the motor. The larger pulley should give a more usable range of winding speeds, at least for the novice. And yes, the very next thing Luke did was to put on his safety glasses and bring his iPod down so we could blast some Pepe Romero flamenco for the build! Yes, I have a 7 year old who want to play flamenco.......... He thinks it will be easy to learn as they just strum really fast........ Some of life's musical bumps just must be hit I guess.

Onward!

Hey All,

Soooo, how to mount the shaft bearings. I cut up some poplar into squares and forstnered recepticles for the bearings. Spritzed a little Behlen's amber on them for effect and was good to go. The original thought was to mount the bearing blocks on the inside of the can but with the motor width and pulled real estate requirements, at least the left one would have to be outside.

Drilling the Can....

Hey All,

I have to say that working in wood for this project probably would have been easier. Drilling flexible tin does not make for accurate hole locations. In retrospect, I should have filled the can with wood solidly so the sides wouldn't deflect. A little grinding with the Dremel rotary file for things usable but one note of caution here, this creates very painful metal slivers that are everywhere and hard to see. Even using a collecton magnet inside was of little help. Holes drilled were for the main shaft, the guide shaft and for the bearing block holding screws. Tomorrow I will drill for the power cord. rubber feet screw holes and the counter hole. The leather mechanic's gloves really helped. Safety glasses will help you avoid a trip to the ER to get metal sliver removed from your eyes.......

Onto the Mock-Up!

Hey All,

Used a template to drill the bearing block screw holes. Ended up with both blocks on the outside. The original concept was to have the winder can big enough to carry all my winding supplies in it as well; a spool or two of wire, eyelets, magnets, etc. I'm trying to get organized here! A version 3 may happen if I still think the original concept has merit. The last picture shows the pulley mock-up. The shaft spins and the pulley fits! The pulley will be cyanoacrylated to the shaft. The assymetrical design will allow for future belt changes if needed. It looks like both shaft set screw collars will be on the right side or I may just slip a teflon washer between the pulley and side and use an internal set screw collar on the right. Back to the hardware store tomorrow.

Tomorrow I'm going to see if I can transfer the guts of the Harbor Freight router speed controller to the can so the speed control knob can be surface mounted next to the counter. We will see. I don't want to get to cavallier with my modest fab skills and temp fate!

Thanks Robbie!

 

Hey Matt and Mod,

Thanks for the kind words guys. I'm doing this not only because I want a better winder but also to help anyone out there who is considering the Challenge next year. Home brew pups will probably be mandatory so why not get equipment together and practice now? It's not rocket science and it's fun! My 2 cents.

Hey Mod,

7.62mm, speaking strictly in terms of diameter, is .308" to me!

Rob

 

Thanks Herb! Well, it came with a handle and was the right size and price. My original thought was a mannequin head with the shafts coming out the ears and the speed control knob on her nose. Add a bouffant wig and I bet it would wind some serious 60's pups. That will be version 3.

Thanks Robbie, I always could use more tools!

Thanks Guit, MG and Milk,

More garage time today hopefully. I've got a set of Firebird pickups to wind for a future build as well as a home brew Tele humbucker to design and wind. This should be fun!
