Re: Bandsaw recommendations

I have an Axminster saw similar to the Record one you listed, it was cheap and is still running quite well. The downside of cheap is setting it up accurately, getting it to run smooth and parallel to the fence is an issue occasionally. If the opportunity cost of buying a better bandsaw is forgoing a...

Re: Video tutes

I bet those videos are going to be brilliant Steve. I’m sure we all look forward to watching them. I had the same idea myself a while back, I got a few iPods recording work from different angles and edited them all with Final Cut Pro. It’s amazing how much work goes into them and annoying how easily...

Re: New Member

Humidity is the invisible enemy! The goal is to match the Relative Humidity in your workshop to the RH in the room where the instrument will live. The ideal is to store your timber in the room where the guitar will spend its days. Takes the wood out when it is being worked on and bring it back to se...

Re: Beginners question

I like to notch in my Xbrace and upper transverse brace into my kerfing. The main benefit for me is that it makes lining up the plates a doddle when I have to glue the sides to the top. Some well respected luthiers believe that this is essential if the braces are to act efficiently on the soundboard...

Re: Stewmac Intonator

A bit of brass block combined with the M3 bolts works just fine. A version to suit Trevor’s bridge design would just need the bolts to be longer at the Outside strings, the brass block could easily sit behind the D and G pegs as there is very little forward pressure. £10 worth of parts, bit of work ...

Re: Stewmac Intonator

The intonator is designed for straight pin patterns and works beautifully. I take a photo of the finish positions and translate this to my saddle. I didn’t buy an intonator, I built my own out of brass bits and Bobs, it’s easy enough to do this I looked for the following on eBay M3 M4 SCREW DOOR HAN...

Re: How do you profile your bridge?

Page 20-8 in the Build book. Make a convex sanding form by either laminating veneers into the top dish that you used (then dress any spring-back by sanding in the dish) or just sand a block from scratch in the dish. I start with 80 grit and it never takes very long (no more than 5 minutes total) to...

How do you profile your bridge?

I have always loathed profiling the underside of my bridges to match the dome of my sound boards, I think I always will, unless someone can tell me an easier way. My set up so far is to hang the guitar by the sound board using a clamp and some stilts, lay down some 120 grit and grind…. And grind ……a...

Re: Tear out

Gentlemen, thank you very much for the advice, I agree that filling it with splinters will always look bad, I will seek out some water colour pencils.

Thanks again.

Tear out

In a moment of absent minded stupidity I pulled off some binding tape to quickly and took strands of the soundboard off with it. The missing fibres also got damaged. The tear out is too deep to sand out and I’m fresh out of good ideas for fixing it invisibly. I have tried repeating the tear out on l...

Re: Pore filling methods question (non-epoxy preferred)

If you don't want to use epoxy and I don't blame you, Mark's suggestion of timbermate is a good alternative, I've got aquacoat here and I don't like it at all maybe I'm using it wrong although I don't see how you can. The shellac method is pretty labour intensive, ok for young guys with good should...

Re: First steel string build - Martin 5 style small guitar

Compensate the saddle. The guitar has taken a lot of effort and looks great by the way, the least you should do now is make the notes sound close to perfect. Stew Mac make the Intonator which is brilliant for getting your saddle spot on. You can easily make one yourself. https://www.stewmac.com/luth...

Just your regular mix for shellac is fine. I agree with you Mark, it should be the first question, wood is beautiful, do I need to make it look like plastic?

Re: Pore filling methods question (non-epoxy preferred)

My preferred method is shellac and wood dust. The dust is the sanded down end grain from the leftover back and sides so the colour is perfect. I then mix them into a very very fluid paste on a plastic board and rub it in with my finger. It’s relatively simple to sand back, it does take at least two ...

Re: Falcate Classical #2 Build (in NZ)

My linings have been around 5mm thick. If I were to make mine 10mm thick then I would effectively lose 65 square centimetres of vibrating plate all the way around the guitar. I wonder whether this ‘loss’ would be balanced out by the ‘gain’ of the soundboard sitting on a much more rigid set of lining...

Love your super thick linings John, that should give a real sturdy rim for the soundboard to vibrate off, how big are they? They look 10mm wide and 25mm deep.
