Solid Body PRS: Headstock and Control Cavity Cover

A bit more progress on the PRS today. I traced the control cavity on the back of the guitar and cut a cover out of a pickguard blank for it. Successive trimming on the bench sander allowed me to get a reasonable fit. Not perfect, but not bad. It's very hard without the original routing template to go by (at least that's my excuse)!



I also got the headstock sprayed black and a couple of layers of Minwax Wipe-on Poly applied. It's not my best headstock attempt, but it will do in a pinch. I really should have sprayed it *before* applying the Wudtone to the neck (like I did for the Stone Roses Tribute) but I did the best I could under the circumstances. Lesson learned for next time > do all your staining and spraying before touching any Tru-oil or Wudtone!

Stone Rose Tribute: Poly Fails == Do-over

Ok so I made the difficult decision today to stop adding the poly to the Stone Roses Tribute and to give up on the finish. Although the paint job looked awesome when first completed, subsequent layers of both Minwax Wipe-on Poly and Cabots Polyurethane had muddied the colours to such an extent that I just didn't like looking at it any more. It was muddy and green and horrible.

Well, C'est la vie. Out comes the scraper..


I haven't had a solid colour build that hasn't involved a do-over. I had hoped that this build would be the exception, but unfortunately not. And I was sooo happy with the paint job on this one too !!! Oh well...

I will be repainting the body in exactly the same manner as before. The difference this time is that I wont be shooting for a level, or even a gloss finish. Just a few layers of satin clear over the paint and I'll leave it at that.

Stone Roses Tribute: Fucking Minwax Wipe-on Poly

Ok, so I'm pretty fucking pissed off. After 5 coats of Minwax Wipe-on Poly, there has been a distinct change in the colours on my Stone Roses Tribute guitar. The colour scheme I had worked so hard to create is now changed beyond repair. The whites in particular now look off-white or "aged". Not sure if you can pick it up in the photos, but under normal lighting the difference between the white of the pickguard and the now yellowing white paint is enormous. What a fucking disappointment.


With hindsight, maybe I shoud have known this would happen. The Minwax product is a "wipe-on" product meant to be rubbed on much like oil finishes. For this reason it isnt surprising that the poly has a very slight amber tint. You dont see it with the first coat or even the third, but by the fifth it's pretty fucking obvious.


This being said, a can labelled [Clear Gloss] is at the very least misleading. Fuckers.  I've since bought another brush-on poly from Cabots that also professes to be "Clear". Dare I continue putting on coats? I've no fucking idea..

Stone Roses Tribute: Psychedelic Pollocking Complete

Well today I finally finished the Pollock inspired colour coats on my Stone Roses Tribute build. With the last splatter coat in place on the sides, this boring piece of basswood has been transformed into a masterpiece of psychedelia :P. In the end the paint job came out very close to what I was shooting for and I think it looks awesome! I just can't stop going back to look at it!




All the masking went exactly to plan. There was quite a bit of paint on the top of the binding, and it took some very careful work with an exacto blade and my binding scraper jig to get it all clean. But, in the end, it's clean as a whistle and looking very professional indeed ;).


Next step is to decide on a way to get this bad boy clear coated. I am strongly leaning towards Minwax wipe-on poly for this one as it will be simple to apply and may well fill some of the valleys between splatter pretty nicely.

Les Paul Jnr Double Cut: Polishing & Cavity Shielding

After a lovely christmas break, I finally got back to the Les Paul Junior today. First task was to polish the Minwax wipe-on poly finish using Colortone swirl-remover now that it's had time to fully cure. This process didn't actually add any more shine to the surface, but took away the 'plastic' feeling from the poly; making it beautful and smooth to the touch.

Once the poly had been polished, it was time to get the cavities shielded using adhesive copper foil. The pickup cavity and control cavity were completed with no issues. I also got the grounding wire from the bridge post installed, and soldered it to the control cavity.



All that is required to do now is to solder up the electronics and get the hardware installed. Should be well worth the wait!

Les Paul Jnr Double Cut: Clear Coats Complete

Finally the clear coats are finished on the double-cut Jnr. I used Minwax Wipe-on Poly - about 4 coats - to help bring up the shine and to protect the finish a little more. To tell you the truth I just wasn't happy with the amount of clear that went on from the Wudtone bottle. Just 3 very thin coats! It didn't feel to me like it would survive the first bump.

So anyway, it's done and even without applying the Colortone polishing compound the poly has  really come up nicely.



Now to let the poly cure completely and then give it a quick buff with Colortone compounds. Should look killer when all that elbow grease has been applied.

Les Paul Jnr Double Cut: Wudtone is On!

So the last coats of Wudtone colour and clear have been applied to the Les Paul Jnr. That makes 8 coats of colour and 3 coats of clear in total. I would have liked to get a  few more clear coats on there, but the bottle ran out. There could have been a little more in the bottle for mind..


Anyway, the colour has deepened well and I'm very happy with it. There's a pretty good solid colour, with just a hint of grain showing through. Should look killer with the custom Tortoiseshell Pickguard I've made. I've allowed the Wudtone to cure for a week and I've started polishing it. Currently I've rubbed my heart out with Colortone medium compound and I also plan to apply fine and swirl remover grades before I'm finished. Gotta remember not to rub too hard on those edges and start taking colour off..

Once the Wudtone polishing is done, I'll decide whether the gloss is enough to call the finish complete and go on to the assembly. Wudtone is not made to duplicate the lustrous shines achieved with Nitro or Poly, so I'll have to see. On Siena's Stratocaster I ended up with a few coats of Minwax Wipe-on Poly, but that was also for protection in addition to the shine factor. We'll see how I feel. I have a new spray gun and am planning to give the Les Paul Florentine a few coats of Vinyl lacquer. Possibly I could bring the schedule forward to include the Jnr?

Jackson-Style Flying V: Poly and Shielding

The Jackson-Style Flying V was my first kit; a project that was not only a learning experience, and one that produced a great guitar, but which cemented new love for guitar building. All those months ago, in those naive early days of my burgeoning new hobby, my knowledge on the subjects of finishing, electronics, and many other aspects of the luthier's craft was sadly wanting. Consequently, there are a few things about the build that, with hindsight, I could have done a good deal better. Whilst the guitar came out remarkably well given my lack of knowledge and wood working skills, there were 3 key areas in which the guitar could have been improved.

The first was in the finish itself. I used Behlen vinyl sealer and nitro lacquer to apply clear coats over the automotive acrylic colour coats. Whilst this is not in and of itself a bad idea, my execution was found wanting. The clear coats were very thin and after sanding through a couple of times, I was too timid at the end of the day to polish them properly to give the mirror finish the paint job deserved.

Secondly, although the electrics were all professionally wired and soldered (I can at least wield a soldering iron with some confidence) the wiring was not properly grounded to the bridge and there was no shielding at all in any of the cavities. In my naivety I tried to solder the ground wire to a bridge post (which I eventually suceeded in doing) but the act of hammering in the post cut the wire. As far as shielding was concerned, I didnt even realize such a thing was done, let alone how important it was for noise elimination. Despite the noise introduced by the combination of these two factors, the Entwistle Dark Star pickups really sounded excellent. But alas the noise was there buzzing away in the quiet moments.

Lastly, although the action straight out of the box was impressively low and comfortable, I did not perform a fret level and re-crown on the neck. In addition, the neck was badly in need of a shim as the tune-o-matic bridge had already been reduced to its lowest setting leaving no room for fine tuning.

And so, desiring one of my beloved guitars to play and sound even better, I thought it high time that the Jackson-style V went back on the bench and receive the finishing touches that it so richly deserved.

First came the poly. Using minwax wipe-on poly, I applied around 15 coats, wet sanding every 2 coats with incrementally decreasing grit sizes: 1200, 1500 and 2000. The body now has a nice thick build up of clear on it, and the sparkle in the metallic auto paint is dazzling. After the wet sanding I went on to the polishing compounds, with Stewmac Medium, Fine and Swirl Remover called in to apply the final touches. The V now has a lovely mirror finish!


Second came the shielding. I used copper foil with conductive adhesive to coat both the pickup and control cavities. Even the plastic control cavity cover got the treatment (this is important if you want to create a complete Faraday cage around the controls). The shielding in each cavity was soldered to the next using joining wires, and the wire from the bridge post was correctly inserted (with vertically hanging bare wires this time) and the connection duly tested with a multi-meter.


The next step for this bad boy will be the re-wiring of the pickups and controls, as I had to completely un-solder all the components to remove them for shielding. After the body has been completely re-assembled and re-wired, the frets can be levelled and this baby can sing again. Stay tuned for the next instalment! I may even make a bone nut if I'm feeling particularly enthusiastic. Yes, I think I will. That's something else I've had experience with since moving on to other building projects and the V could definitely benefit from it.

BC Rich Avenge - The Beast Roars!

Well, Eben and I put the finishing touches on the BC Rich Avenge kit today. The chrome hardware looks awesome against the blue metallic paint, and the whole genre crossover lends this guitar a much more engaging look than just your standard black metal monster etc.

For those about to rock..!
Eben couldn't be happier with his new axe. I must admit that, while the whole BC Rich metal thing is not really my style, the finished guitar looks absolutely spectacular hanging with my others. Unbelievably so. The hot-rod flames came up a treat, and I think the colours that Eben chose were perfect for the design. I can't think of any other combation that would have worked as well.


The Entwistle HBX pickups sound absolutely awesome through my overdriven Fender Reverb amp, and I would again recommend Entwistle pickups to anyone in the market for an affordable option to their stock offerings. Surrounded by chrome rings, these pickups look the shit and sound it!


On the negative side, I must say that I'm not too impressed with the Minwax wipe-on poly, at least for guitar applications. It may have been because we didn't allow adequate curing time, or that we simply didn't put enough coats on (although we did close to 20 by my estimation), but the poly seems to chip at the slightest bump, an lifts when drilling through it. Not at all what I had expected.


In conclusion, I am very happy with the build. The original kit from Pitbull was of high quality and fit together perfectly without the need for neck shims, or any kind of body or cavity modification. Whilst we had to do the paint job twice, (maybe one day I'll have a build with no do-overs) it came out much better than expected for a noobish first attempt at flames. With a fret level and re-crown the action on the guitar is sweet. The only thing it is lacking is a new bone nut.

To be honest, the result is so damn good (not to blow my own trumpet or anything ;) ), that I'm now planning a future telecaster build for myself with exactly the same flame paint job. Keep your eyes peeled for that one!

BC Rich Avenge - Hardware Going On!

We got most of the way with the hardware today on Eben's monster. We chose flat chrome humbucker rings (my favourites as regular readers would know) to compliment the existing chrome hardware, and to increase the amount of bling given the large expanses of blue we have created here.


All that's left now is to string it up, set the action and intonation, and let her rip. Stay tuned for completion pictures and an assessment of the Entwistle HVX pickups!

BC Rich Avenge - Shielding & Pickups

A little more progress on the BC Rich Avenge build with my son Eben this weekend. We managed to get the top and back wet sanded and buffed (although not as nicely as I would have liked - this poly is not behaving itself, and patience is not a 9 year old's virtue) and also got the pickup cavities shielded.



After shielding, we grounded the bridge and installed the pickups with their chrome surrounds. The pickups are the Entwistle HVX which I have read rave reviews about. I was looking at some Entwistle soapbars for another project a few weeks ago, and my son saw the HVX's and had to have them (go figure). Anyway they look great and I'm sure will sound awesome. I would have preferred Entwistle Darkstar pickups on this particular project (given the thrasher motif) but I was overruled.


Anyway, things are nearing completion. Just the neck to go on and the control cavity to do. We have already had plenty of fun soldering up the wiring harness, so that can just drop in now. Sounds like next weekend's project!

BC Rich Avenge - The Custom Decal

Still getting the layers of poly onto the BC Rich rockabilly death metal thrashmeister. The poly is taking roughtly 24 hours for each coat to dry, so it's a long plodding process with few results to report. In the meantime, Eben could not wait to put his custom decal on the headstock. So, executive decision made, we went ahead and applied the sucker!


The result is not quite centered - it's a tiny bit off to the right - but it still looks awesome. Eb is very happy with the result. A couple more coats of poly over the top and the headstock will be ready for a rough wet-sand and polish. This bad boy is going to look awesome when it's finally assembled!

BC Rich Avenge - Poly, Poly, Poly

Slow progress on the rockabilly death metal beast that is Eben's hot-rod flamed guitar. We are in the process of applying layers of Minwax wipe-on poly in between homework, music lessons and other after school activities.



I gotta say though, this wipe-on poly is the shit man. It's basically idiot proof - goes on easily with a piece of old tshirt, doesn't seem to run or misbehave, and dries in 24 hours ready for the next coat. A little 0000 steel wool gets rid of any little greebles that may have settled on the surface in between.

We are trying to get to about 10 coats before we finally wet-sand and polish this bad-boy with Stewmac polishing compounds. More updates to come!
