Re: Saddle position

Ahh - OK, use of the truss rod to compensate for the forward neck relief was the bit that I was not mentally factoring in. You make a good point that if string tension raises the action it should be doing so by increasing forward bow of the neck - and you have a truss rod there to correct that. In m...

Re: Saddle position

With regards to the bridge height, I normally aim for the straight edge to be just be kissing the top of the bridge. I can't quite tell what sized gap it is but anything more than say a mm is too much. Even a 1mm mil is pushing it. Trent, do you expect to see the straightedge lining up with the top...

Re: Building a Selmer Maccaferri guitar

The book arrived already. Thanks Mike. Thanks also Ross for the additional advice. I had gathered that solid linings are significant part of this style of build. I will need to pay careful attention to the neck and soundboard geometry. What are your thought on solid wood versus laminted back and sid...

Re: What dimension for bridge

When string tension goes on it will pull the neck forward a bit, and the top will be pulled up a bit, so the position of that straightedge will drop some. Trent is right in saying that the ideal situation is when the straightedge just kisses the top of the bridge. Then the neck angle is correct and ...

Re: Works in progress.

Thanks for the quick photography tutorial Frank. That is really useful. You might see me copying it in future. I will also need to work on how to “smudge out” the defects in my instruments as well as artefacts from the photography.

Re: Swamp kauri + epoxy resin bass

Hi Nikolav. The blue resin and brown/black timber look great together. You could be getting into a signature style there. You might like hand applied oil finishes. Danish Oil looks good but is not the most durable option, and the lots of different brands all calling themselves Danish Oil are a mixed...

Re: 13 frets Prima-R in Padauk/Bearclaw Sitka

Really well executed. I love the shell shaped inlays - but I assume they are timber. Do you make a log of those? What is the secret of their perfect regularity? Or is this some kind of CNC magic?

Building a Selmer Maccaferri guitar

I have a mate who would like me to build him a Maccaferri-style guitar. I actually have the two sets of plans produced by Francois Charle (and I am armed with some advice from Ross that those plans have a problem concerning neck angle). I have seen a number of recommendations for the book "Building ...

Re: Saddle position

Hmmm, that does look a bit close for comfort. That curved arrangement of the pin holes is a nice look, but it does make it a bit tight at the bass end. I think you have a few options: 1. Move the bass end of the saddle slot forward 2-3mm. This would make it essentially perpendicular to the centre li...

Re: Saddle position

First thing I would suggest is go up to the local hardware store and invest $20 in a metre long steel ruler. You really need to be able to measure this stuff accurately. You are on the right track with the measurements. If nut to 12th is 322.6mm your overall scale length is double that at 645.2. Tha...

Re: Saddle position

Get back to us with the measurements, and maybe a photo of the bridge. If you need to remove the bridge we can help you to get that done. Don’t ask me why - but I have removed the bridge on a few of my builds before. The falcate bracing, because of its close relationship to the position of the bridg...

Re: Saddle position

Can we check how you are calculating the right place for the saddle? Presumably you have measured the distance from the front of the nut to the crown of the 12th fret, and then you doubled this, and then you added a bit for compensation - and that lands you on the spot that would be the front edge o...

Re: Long time no build

Yes, the new frets will probably cover up nearly all the chips. For any bigger ones the sawdust and CA remedy will fix it. That figured timber will hide blemishes really well, just as long as you fill any divots. The whole instrument is looking great.

Dave You can use any form of bracing you like, and X-bracing is certainly tried and tested. Falcate is just another way to do it, and it is becoming popular- but the bracing pattern is not really what we started talking about in this conversation. It is about getting some objective data about the st...

Re: Long time no build

I have seen a recommendation by Frank Ford (frets.com) to heat the fret with a soldering iron to loosen glue before pulling them. I guess this would work best for a PVA or hide glue - maybe not so well for CA, but it could be worth a try if you find them difficult to remove. But it sounds like they ...

Re: Long time no build

That is a setback for sure, but fixable. Are they all loose? If so, there is not much option but to remove them as gently as possible and have at it again with new wire. Did you glue them in? If not, and if it is just a few of them causing problems, you could wick in some thin CA glue to the slots o...

2mm is getting a bit thin, but a parlor size guitar can be a bit light all round and get away with it. Just be careful with the sanding and you will probably be OK.

Re: Long time no build

The best way to fill those gaps is to raise a bit of sawdust from your back or sides and pack it into the gaps, then wick in some CA glue. Overfill it a bit and then sand flat. The gaps will completely disappear.
