Everyone has different ways of shaping a new nut or saddle from a bone blank. Is there a right or wrong way? Nope. There are definitely ways that are a lot faster than others. It typically only takes me about 5 minutes from start to finish…possibly less if I’m in a hurry.

Let me show you how I make one in our shop.

Size difference
Here you can see how much material is needed to be removed. It is a lot, especially if you are going to try to sand it all away.
Board and template double side masking tape
The secret to getting the thickness down quickly is to use a table saw, a long board, and our template double side masking tape.
Bone blanks attached to board
Next, attach the double side tape to the board and then attached bone blank. Make sure to put some pressure on them to make sure they are securely attached. I like to attach the original nut (or saddle) in front of the blank to use as a guide for setting the thickness.
Adjust table saw fence to thin nut blank
Place the board against the fence and set the thickness I want the blank to be. I sometimes like to leave it slightly thicker so I can fine-tune the thickness later especially when making an acoustic saddle. Here, I am using the original nut as a reference. You will need to remove it before cutting the nut blank so it doesn’t get accidentally damaged.
n the bone nut through table saw
Definitely make sure to use a zero clearance insert on your table saw so you don’t lose the blank in the saw. I should also add, you want to use a large enough board so you can keep your fingers well clear of the spinning blade.
Half way through the bone nut
Here we are about halfway through the bone nut.
Picture of the thinned bone nut
OK, so there you go, a bone nut blank thinned to size. Since I’m already set up, I usually will run a few more nuts though so I have a few extra for another job or if I mess up this one.
Tracing the shape onto the bone blank
Trace the shape of the nut onto the blank.
Using small tabletop bandsaw to cut out shape
Here I am using a small tabletop bandsaw to cut out the shape. Make sure to stay slightly outside the line. This can also be done using a tabletop scroll saw.
Cutting outside of the traced line
Here we are almost done cutting out the shape. I think this was actually a bone saddles instead of the nut shown in previous images.
Using a belt sander to clean up shape
As you can see, cutting a smooth shape on the bandsaw isn’t critical as long as you stay outside the line you drew. Be careful of your fingertips! I need to come up with a better way to hold on to the nut blanks when profiling them on a belt sander.
Sanding a single facet for nut
The nut on the left was just belt sanded with one single facet. The nut on the right is the original nut. I don’t try to make the shape perfect on the belt sander since it can remove material pretty fast.
Saddle with double facets
Here is an acoustic saddle with double facets.
Use a Hosco Nut and Saddle file to shape the nut
Here I’m using a nut and saddle file to remove the facets and blend the sharp edges. The nut is held in place with the StewMac Nut and Saddle vise…almost an essential tool when doing this type of work.

Final sanding using a foam sandpaper
Here I’m using foam backed sandpaper to finish the shape and smooth everything out. I typically use 4 grits…120, 220, 320 and 400 grit using the 120 grit for the majority of the work. The other grits are just removing the scratches from the previous sandpaper.
Use a foam sanding pad on a table
Here I’m holding the nut with my hand to round an edge to get the look I’m after.
Nut and saddle ready to use
You are basically done here. The matte look is very common. You can go one more step further by polishing them on a buffing wheel. You can get some awesome looking nut and saddles that way.
Polishing nut and saddle using a buffing wheel
What I’m using here is a small buffing setup that I bought from Penn State Industries (MCLS Woodworking). These are sold for buffing pens but are very handy around the shop for buffing all kinds of small items include bone nuts and saddles!
Loading up buffing wheel with compound
I basically only put buffing compound on the left wheel. I have nothing on the right wheel. I found I can achieve a very nice finish this way. BTW, here I am loading up the left wheel with Menzerna GW16 Finishing compound.
Polishing a guitar nut on buffing wheel
Remember to only use the bottom front quadrant when buffing so you don’t accidentally throw the nut at yourself. After buffing with the left wheel, I finish on the right wheel that has nothing on it. I have found that no compound is needed to get the great glossy look.
Completed bone nut and saddle
You will be amazed how nice these look after buffing. They almost look like polished stone!

Some final thoughts or questions that some of you might have.

First, is a using a table saw to thin blanks…dangerous? I think so, especially if you don’t know what you are doing or are at least confident in using one.

Second, will this screw up my table saw blade? I haven’t found that to be a problem. I do use a quality carbide tipped blade and never had an issue going back and forth between wood and bone. I have found that a good quality blade will give you a better finish every time whether on wood or bone.

Third, does the type of double-sided tape matter? Yes, absolutely. Use the best you can get. You don’t want the nut blank to come loose when you running it through the table saw. The blank can be a very dangerous projectile.

MG-T thumbscrew-style locking tuners use a very simple functionality for locking and unlocking of strings with Gotoh technology.

GOTOH uses standard rotation of thumbwheel to lock and unlock the posts….think..righty-tighty…lefty-loosy.
Notice: Please be advised that thumbwheels do not need to cranked super tight to lock the strings. The specially designed locking pins are rounded to kink the string to help prevent the strings from working loose. Over-tightening the lock can possible break the tuning machines.

Post Dimensions Option

The MG-T are available in 3 different post heights/lengths.
You can choose several combinations for your own staggered posts.

MG-T Post Dimensions
The 3 dimensions Short 18.5mm, Long 20mm and Extra-Long 21.5mm are available.
Standard set for L3 + R3 are all Long 20mm posts.
Standard set for 6 in line for both strat and tilt back headstocks are 3 x Short 18.5mm for 1st-3rd strings and 3 x Long 20mm for 4th-6th strings.
**An exception to the 3 short and 3 long posts would be when installing on a guitar that has a thicker than normal headstocks like some ESP/LTD guitars. In this case, your would use 3 long and 3 ex-long posts.

The Stud-Lock® mechanism is implemented to all of GOTOH’s 2 post anchor type tremolos (510, GE1996 and Wilkinson series) and 510 series bridges and tailpieces. This mechanism removes the gap between the height adjustable stud and anchor by the stud-lock screw inside of the stud. As the results, you will have better and enhanced tone transfer from the strings to the guitar body.

GOTOH Stud-Lock Bridge Posts

① The stud-lock screw penetrates through inside of the stud.
② There are two Allen head adjustments are inside of the stud. 1.5mm for Stud-Lock and 3mm for stud(bridge) height.
③ Insert the 1.5mm Allen key to make sure the Stud-Lock screw is fully inside the studs.
④ Insert the stud into the anchor and adjust the height by 3mm Allen key.
⑤ After the height is determined, insert the 1.5mm Allen key again and tighten the stud-lock screw until the screw touches the bottom of the anchor.
⑥ Then tighten more firmly to make sure that the stud doesn’t move.

** CAUTION:When adjusting the bridge height, make sure your strings are loose. If you make this adjustment while your strings are at normal tension, it may cause some wear on the bridge plate where it presses against the stud.

30. April 2018 · Comments Off on Printable PDF for Measuring Pickup Pole Spacing · Categories: General, Tools · Tags: , , , , , ,

One of the most common questions we get is “What pickup covers will fit my guitar?”. Sometimes I actually do know what size cover will fit a specific pickup. A good example would be “What covers will fit a Gibson ’57 Classic?”. The Gibson ’57 Classic need a 1 15/16″ (49.2mm) pole spaced covers. Easy. A harder question would be “What size cover do I need for my Gibson?”, “What fits a PRS SE?”, “Do you know what size covers will fit a Bare Knuckle Pickup?” or “I have a guitar from the 1970’s, what size should I order?”. My standard answer to all those questions has always been “Please measure the center to center distance between the two outside pole screws”.

OK, let me get to the reason for this free downloadable PDF. I had a customer ask me a few weeks ago what is the correct size he needs for his pickup. I gave him my standard response to measure the center to center distance… His reply was “do you really think I can tell the difference between 1mm!”. That actually got me think that there must be an easier way because deciphering all the small lines on a ruler can be difficult and also error-prone.

So my solution is this printable PLTS Pole Spacing Tool. I set it up to only show one pole spacing at a time so there is no counting the little lines on a ruler. All that needs to be done is line up the dashed lines to the center of the pole screws. It is set up with all of the pole spacing we offer at Philadelphia Luthier Tools…48mm, 49.2mm, 50mm, 51mm, 52mm, and 53mm. I even added fold lines to help you fold the PDF so it will easily fit under the strings.

Here are some helpful hints for printing and using this tool. First, very important, this PDF needs to be printed actual size with no scaling of the page to be accurate. it has probably defaulted to something like “90%” or “fit to page”. You will have to look around since they aren’t always described the same way or sometimes hidden. I use Google Chrome browser. When the print dialog box comes up, it is hidden under “+ more setting”. The setting is called scale. In the case of Google Chrome, you want to set the scale to be 100%. Included on the printout are 2 square boxes. One represents 1″ and the other 25mm. Only use the tool if they measure exactly 1″ or 25mm.

Second, make sharp creases when folding the PDF. It will help tremendously when measuring the pole spacing. A loosely folded paper won’t allow you to get close enough to see the center of pole screws accurately.

Third, always measure all of the pickups. A lot of manufacturers will use a different pole spacing for both the bridge and neck pickups while others will use the same for both positions.

Here are some pictures of how to fold and use the tool.

Step one in folding the PLTS Pickup Spacing Tool

First, crease and fold at the outside fold marks inward.

Step two in folding the PLTS Pickup Spacing Tool

Second, fold the next two marks towards the center.

Hand polished unplated pickup cover

Last week I showed you how to achieve a brushed metal look using a Scotch Brite pad and a non-plated pickup cover. Next, we will hand polish a raw unplated pickup cover and then make it look like an aged pickup cover with faux string lines.

First, you will need a metal polishing compound and some old rags.  Any brand metal polishing compound will work fine.  You can use the metal polish impregnated cloth called “Miracle Cloth”. This is what I used to achieve the look you see here. It works great for polishing frets too. One warning about metal polish….don’t use it to polish any gold-plated parts.  It can strip the gold plating off very fast!

PLEASE READ:  We recommend you wear protective gloves while working with unplated pickup covers. The bottom edge can be very sharp and can easily cut your finger. Filing the bottom edge smooth before you start work is also an option.

We will begin by applying a small amount of metal polish to the rag and rubbing it into the surface of the pickup cover. Use circular motions until you have covered the entire surface. Periodically, wipe off the polishing compound to see how you are progressing. If you are happy with the result, you can continue buffing until the pickup cover is bright and shiny. Use a new cloth or a different area of the cloth when doing the final polish.


Hand polished unplated pickup coversNow that we have a nice hand polished pickup cover, lets add an aged look with faux string lines. You will need some painter’s masking tape cut into very thin 1/32″ strips and some very fine grit Micro Mesh soft touch sanding pads.  The three highest grits (6000, 8000, and 12000) will work best because you only want very light marks.

1.  Lay out the thin strips of painters tape over the screw holes to simulate the string location and then trim the extra tape.   Applying some pressure on the tape will help keep it in place during the sanding process.

2,  Sand lightly with Micro Mesh soft touch sanding pad.   It will take some experimenting to get the right look.   Try pressing the sanding pad into the edge of each piece of tape.  This will help emphasize the string line.

3.  To help soften the look, I like to rub the front of the pickup cover on an old piece of carpeting.   Here I am rubbing the pickup cover on the carpet on my workbench.

4.  OK…it’s all done.  This is not my best work but you get the idea.   The nice thing about working with unplated pickup covers is you can easily re-polish the cover and start over if you don’t like the results!
