Thanks.....It's just more fun this way...
In honor of the 2013 TDPRI Challenge, I ordered the extruded aluminum radius block from stewmac that I've been pining for a couple years. I decided I'm not getting any younger. Should make the final truing up of the fretboard a lot better than the wood one.
Probably will be here tomorrow as it is in the mail already. Stewmac is perhaps the best company I have ever dealt with....
Come on, Marty, I gotta pick on someone or all these mod powers will go to my head.
Marty, love the work you do. This is very interesting.
Phil, you really want to disqualify someone, don't you?
An aluminium caster made with CNC is outside any category.
What's aluminium??? LOLOLOL
Thanks!...not much happening today except garage band practice.
+1.There are other companies I deal with that have a wider selection of wood, but when I need it good and fast StewMac is the go to.
Another great build Marty!!!
Thanks for your support!
Other than preslotted fretboards, I go elsewhere for my lumber purchases. For acoustic woods I lean towards LMII or Allied Luthiery. For Swamp Ash, exoticwoods.com, and alder can be had all over ebay.
Rounded the corners on the neck heel and tried the fit. Maximum mojo transfer...no glue or screws here:
I decided to pay for photobucket for a few months. The uploading is about 10 times faster.... funny how that works.....
Anyway..... Shift gears again.
Today's Lesson......... Fun with the pickguard.
I had my drawing done, but needed to create a toolpath for the cnc. So I created some edges and saved them as a DXF file. Then I opened a program called CAMBAM. This is the trial run program. You can buy it after about 40 uses. It works pretty well so far.
This is the DXF file loaded into Cambam
This is the tool path that Cambam generated.
The Gcode is a bunch of alphanumeric characters which is in a Notepad Text file....not shown.
I taped down the pickguard material to some cardboard. That is so I don't cut into the aluminium... I zero the machine at my start point and set the cutter to the top of the plastic. Then I hit " start"
What you don't see is the machine skipping steps or more likely,the plastic ....probably the plastic.... sliding... so the first one get messed up. Luckily the pickguard material could be turned around and I could start again and still get a complete guard out of it.
Cnc cutting the parts. I went out to buy a cheap bevel bit because I couldn't put my fingers on my good one.
This is a black control plate out of some leftovers
These are the parts
This is how the stuff looks on the body right now
This is the tele copy I'm copying...well sort of
So as you can see....you press the button...and out comes a bad part.... Then you fix the problem.... press the button...and out comes a good part. Much like using templates.....
The pickguard and control plate will need to be scraped to get rid of the excess plastic. I'll have to decide if I'm going to add the switches too and deal with those holes.
killer work as usual
Thanks for checking in. It's just different....
The build's looking great Marty.
Man, I wants me a CNC mill!
Thanks!....if you get one or build one...make sure one axis can go about 36". Mine is only a 25", and that limits me a bit on necks.
Back of peghead got sanded flat on the edge sander
Put a straightedge along the fretboard sides and scribed a couple lines forming the taper. Then found the centerline by dividing those two lines by 2 with a machinist scale.
I centered the neck on the CNC. I could have rigged up a router planer jig..but this is the same thing. I used to clamp a block up on the drum sander...but had too many occasions where a dip was sanded into the peghead and didn't want that here.
I have this bit I got at Sears a long time ago. It was for using a router to make cove moldings. I used to use it in a radial arm saw to do the transition curves on my early necks. Now I chucked it up in the cnc and inched close to my nut edge line.
Then I replaced the cove bit with a 3/4 straight bit and finished nibbling away at the surface about a 1/4" at a time.
until it looked like this
took off the two clamps
and sanded it up some... Pizza Anyone?
I guess I need to make a peghead template or toolpath now.
