How to Build a Guitar Pickup (Part 2)


what’s up guys this is chase from Chase’s
workshop here by the end of this video we’re gonna have a bobbin ready for
pickup wire right here I’m using a technique that I learned from Crimson
guitars where you use painters tape and super glue to hold parts down I’m just
using that technique to hold the bobbin material down to my CNC machine I worked
with awhile I’ve used it for a lot of things I’ve actually used it to hold the
bobbins to the pickup one or when I’m winding the pickups I’ve used it to hold
neck templates down templates down to neck blanks to cut them out and while
I’m writing them very versatile it works really well right here I’m holding it down for about
15 to 20 seconds just long enough for it to actually dry once it dries it it
holds really well you right here I’m using a 8 inch – flutes
spiral up cut router bit in the CNC machine right here I’m setting the zero
access to 0 I’m setting the z-axis to 0 I’m sorry I meant to say and now I’m
going to set the X&Y I will say there’s a view if you’ve always wanted a CNC
machine but never thought you could afford one or or buy one I had that same
problem about a year or so ago before I built this one I found a guy on YouTube
named Dave Gatton and he actually says kits that you can buy and I actually got
in touch with him before he started selling the kits and I made a donation
and he gave me a templates for for the CNC machine and over time I built all
the parts and bought the parts and I’d say I’d say over at least six six to
eight months and running there I went through and bought all the parts are
needed and by the end of that I had a sensing machine and he’s the old
computer that I had you don’t have to have a big powerhouse computer to to run
these things if you’re interesting that I would suggest you check him out he’s
got a lot of good videos on how to build them you here’s the flatwork bottom flatwork i
actually didn’t use this one for the rest of the video because I made a
mistake and use the wrong CAD design that I made for these had to recut to
new ones I use the same process the actual CAD program I uses it’s called
fusion 360 and it’s actually free if you make less than hundred thousand dollars
a year using the program so I didn’t have any problem with that but it works
really well and it’s like I said it’s free the actual cam software I’m using
is called Mach Mach 3 and again like Dave cat and he can go over a lot more
about that and the things that you need for that you and there’s the top flatwork right here
we’re actually going to use an 80 grit sandpaper to clean up these bobbin he’s
this flat work it’s real important that you get these really smooth because you
have any Nick’s or anything on a munch when you go to whine these things you’re
gonna it’s going to catch water just gonna make a mess when you when you do
that so I just used 80 grit and some routes around piles and some flat files
to kind of clean them up real good and all this will be smooth out too when we
add the lacquer there they are clean right here I’m
using the compass to kind of just to check to see what polarity I have on
these these pole pieces I don’t know if this is really necessary but I’ve always
done it but you know if these actually come they said when they when they come
in the mail they say that they’re not you’re not charged at all but they do
have a little bit of a polarity on them so like this one here is not be but it’s
not shown hardly anything on the compass but you can obviously see that one’s got
some polarity to it I just try to align them before I put them together you I’m actually going to take a hammer and
add these puppies to the flat work they didn’t actually fit as well as I wanted
them to one of them to be a lot tighter than they are but I just went with it
and we’re going to see how it goes you once we get all the bottom pieces in
we’re gonna attach the top piece you let’s forget it together there’s going
to be some spots that you on the top of the pickup that you’d want to clean up
it’s where the PO pieces are Shawn and I even take a piece of sandpaper again 80
grit and just kind of just came over the top of them to get them to look right right here I’m actually using some
superglue on the back PO pieces just like I said earlier I didn’t they didn’t
fit as tight as I wanted them to and they were they were tied but not not
what I wanted so I thought I would shoot a coat of that on there to see if I
could hold them better now we’re going to use the guitar lacquer nitrocellulose
lacquer and we’re going to dip the pickup into it I’m just going to use a
piece of copper wire and once I dip it in there I tried to get sideways I
thought I’ll dip it in there and let it soak for one or two minutes just let it
sit and pull it out and let it but some of the drips get off of it I turned down
that side because I want the biggest thing on this is not to get any runs or
anything like that on your flat wart or bubbles on your flat work because if you
do like I said earlier when you go to put the wire on these it’ll catch it’ll
catch the wire and cause a mess and I’m just kind of hitting the paper with it
to kind of absorb some of the the lacquer that was left it puts a nice
sheen on the pickup to what she wants you do this now I’m just inspecting it
for any of those bubbles and stuff that I talked about earlier here I’m
measuring out to put the eyelet set to put Alex in the pickup I’m using a screw
to actually start the hole where I want the holes up and I’m using the drill bit from the
eyelet setting to torque it to draw the hose used a screw to kind of hold it in there
to work and push them through you want to push them in from the top from the
top down I’m just using a pair of vise grips here to kind of get it through the
house if it’s really tight you alright here I’m using a half inch piece
of aluminum as a backer to install these eyelets you want a really hard surface
on the backside of it when you hammer this down so you get a good you spread
the eyelet out good on the bottom and once I get the bottom done I’ll flip it
over and do the same thing to the top because again these eyelets the tops of
them are kind of rounded and you want that you you wanted a real smooth finish
on the top for the same reason as we talked about with the lacquer and stuck
that you don’t you don’t want to pick up any wire as you’re winding the pick up
you want it to be smooth and a good finish you I will get a pickup bobbin ready for
wire hopefully in the next video I’ll have I’ll be wanting the pickup and
potting it and all that have you have any questions about it or any comments
leave them below if you like it I appreciate you subscribe I’m trying to
get a video out once a week right now I’ve been getting them out about every
Wednesday so like I said subscribe thanks for watching guys you
