Re: french polishing courses/tutorials?

I found a sequence of 9 videos by Pablo Requena, a builder in the UK. They seem to be all in the 20-25 mins range. I looked at the first 3 so far. He is using epoxy as a grain filler for the back and sides and pumicing the neck.

Re: french polishing courses/tutorials?

Thanks for all the comments to date. I have also being reviewing the relevant section in "the books" :-) I looked at some Richard Howell videos a year or two back. It was a quite different approach to anything I had seen up to that point and one thing that stuck in mind about the technique was his v...

french polishing courses/tutorials?

I want to improve my finish work. So far I have done light french polished shellac finishes but would also consider any brushed on finishes. I started off with the Milburn tutorials. I am up around 25-30, mainly classical, guitars at this stage but my finish is not as professional as it could be. I ...

Re: Trevor’s video by Robbie

My mic is on an adjustable tripod microphone stand so it should be OK.
I suspect there must be more devices "leaking" a 50hz buzz not just the transformer.

I grabbed the video too. :-) I have just been doing my first attempt at measuring wood properties. Not as easy as Trevor makes it look. I haven't done the calculations yet. I need to set up the spreadsheet first. Lots of noise pollution sources. First one is the power supply for the pre-amp for the ...

Re: having a go at spectrums

Got my microphone set up this afternoon and had another go at getting a spectrum. Do these look better? My immediate reaction is that they are both quite similar. One is very recent, the other is about 2 years old. Construction is also quite different but both are clearly "guitar shaped objects" to ...

Having read your comments I tried the crappy mic on a mac (audacity) and a win10 (VA) along with there internal mics. It was qu...

having a go at spectrums

I have two classical boxes closed up and will be putting the bridges on in the next day or so. Unfortunately, I don't have my "books" with me and with our current lock-down (Spain) I doubt if I will seem them again for a few months. I made an attempt at spectrums just now and really don't know where...

how thick should a Uke headstock be?

I am making myself a tenor Uke from left over bits and pieces. The neck is getting patched together from a leftover, broken readymade classical guitar neck. I need to attach a headstock. As I don't have a printed plan, and don't have tuners yet, I am in the dark about the correct headstock thickness...

3-10 minutes is pretty good going! although i havent bent mahogany before... maybe its a piece of cake!! im around the 15-20mins per side mark. a wet rag at the waist helps to avoid scorch marks. holding the shape after you take it off the iron so the bend holds is also recommended... The trick is ...

Re: Side bend question...

Any mahogany I have used (mainly Khaya) has bent very easily. I would advise you to make a bunch of sides from any kind of mahogany you can get your hands on. Thickness to between 1.8 and 2.2 mm and bent a bunch of sides. Thinnner is easier. In Europe one seller gets rid of reject wood this way. Som...

Re: Cupping with Mahogany

The older generation of German luthiers, pre-aircon, pre-dehumidifiers, were of the opinion that you prepared everything and then did all the bracing, top and back, and closed up the box within 24 hours. In other words, they locked everything in before the humidity could change much when there was a...

Re: Well, here we are, what now?!

Hi Nigel,

Congratulations! I have only been to Oz once and loved it: my immediate reaction was that I'd love to move there. But alas I was way too old then to even think about it. And now … even older.

Good luck there.
