    I haven't been able to measure any change in resistance, capacitance, or overall sound between unpotted and potted. It's plastic, filling the space between the wires.

    I haven't seen an actual specification of the viscosity of CPES, but it's somewhere between alcohol and water, about like the super-thin CA glue. It definitely fully saturates tightly wound wire...

    Bob;

    I've been potting all of my pickups with a special super-thin epoxy called CPES (Clear Penetrating Epoxy Sealant), made by Smith & Co. It's a two-part epoxy, with a viscosity about like...

    If you are looking for some general information about designing and building pickups from scratch, we have a thread going on over on the TalkBass Forum (yes, electric basses), in the Luthier's Corner...

    I've been getting my Alnico rods from Cullen-Legois Manufacturing in Sturtevant, Wisconsin. They are a small manufacturer that specializes in magnetic tools for the machine shop. They also stock...

    I played around with these when I developed and built my winder about 13 years ago. I built mine with a nice industrial Baldor DC motor and speed controller. It'll adjust smoothly from zero to about...

    Actually, I'm left handed too. And, because it's my machine, I built it so that all the controls are over on the left side. I sit with my head straight in line with the bobbin and work most of the...

    I designed and built it myself, about 12 years ago. It's what you would call a semi-automatic linear-feed winder. The feed is mechanically synchronized to the spindle rotation, but it's driven by...

    I mount the 5 lb spool back behind my winder, with the axis nearly horizontal. It's tilted up about 10 degrees, back about 12", with the center pointing almost directly at the spindle. It's a simple...

    David, that seems low. I wonder if you have something else causing the shorting problem?

    I'm running #41, which is slightly heavier, but it's single build. I wind at 1000-1200 rpm, automatic...

    Yes, that's the right kind of tension gauge, and the right measuring range. It measures tension by the side-to-side movement of the tip of the lever. Hold it in your hand and gently push sideways on...

    This is the type of tension gauge that you want:
    Mecmesin Tension Gauge | eBay
    This is a 0-50gm gauge for $10. Look for one with a range of 0-30 gm or 0-50gm. For most pickup winding, you'll...

    I think that max speed spec is a misprint. Rotary counters of that design should have no problem doing 3500 rpm. The rotary counter that I have on my winder, which is a nicer quality model, is rated...

    I may be there for one day. I'm not sure yet. I never have a booth there, because I only sell my basses directly to the public. I don't use dealers, and I'm not interested in selling to dealers....

    Ken;

    How do you do the embossing? An EDM-cut steel die and a press? I'm thinking about doing that for some of the parts I make for clients, like aluminum neck plates with logos. Right now I use a...

    Well, yeah. I'm a pro Luthier, and I have a fairly complete machine shop, as well as my woodworking shop and electronics lab. I made up my own auto-feed winder including all the face plates and...

    Yes, that one that Tee referred to was made by me. That's a simple low cost design for small plates, like 3". It's just a slug of 3" bar stock, trued up and accurately bored for the spindle shaft. I...

    Hey Chris;

    A quick suggestion, now that I see what you are doing. If I make the face plate for you out of 3" diameter aluminum, I can easily cut a V-groove around the OD of it. Then it can act as...

    That CriCut machine is very interesting. So, it does a decent job engraving aluminum? Do you just feed flat sheets into it? I may just get one of those machines.

    I have a fairly nice German CNC...

    I hope you understand that we are now at N-7; that is, 7 days until the NAMM show. As usual, I'm in a mad scramble finishing up several instruments that...

    Tee;

    Another alternative is to buy thin brass sheet. You can buy it as brass shim stock from industrial suppliers, or get little sheets at hobby shops. You can get it all the way down to 0.001" if...

    I agree. On my own winding machine, I've made up aluminum disks for each bobbin size that I use, which have recesses to fit the bobbin flanges. The disks are also flared a bit around the perimeter,...

    Huh. Maybe you just caught her on a grumpy morning. Or they may have a distribution territory agreement with their supplier. Call the other place, I guess.

    Yup, that's the idea. More magnetic horsepower. Magnetic field strength is approximately proportional to volume/weight of the magnet (assuming all else is equal). Most of the pickups that I build for...
