When the front literally has no flat gluing surface in some areas and the least intrusive method available to us, is to run a gouge along the area and to take a large shaving with the same gouge from a piece of matching spruce. It usually takes more than 1 attempt, then it’s chalk-fitted and glued on.
This sequence of photos show an example of a rib having been damaged along the top from repeated removal of the front over the years and needing to be built up in height.
I always check the edges against the light to make sure the colour goes from a dark to a very light orange – only then are the edges thin enough for a shaving to be pressed on in the cast. I use a gouge as well as scrapers and sandpaper to achieve this.
The first shaving has now been glued across the area. 🤞
Continuing with the lower bass side f-hole today. The wing crack was very open and will need a shaving to cover it before I start gluing larger shavings across the area.
Following on from a recent post about re-shaping a viola neck, this time-lapse shows the process of applying retouch around the chin and the heel as well as putting on some oil at the end.
The slower version of this video will be published on my YouTube Channel.
I am truly humbled and very grateful to Becky Houghton for sending in this review of my online teaching! 🙏
A quick snapshot from some work I’m doing on my bench at the moment, returning the f-holes back to their original position.
I find ribstructure work among one of the most challenging in restoration procedures.
In this instance, the whole of the ribstructure and back had twisted quite badly but the main problem was, that the front had been pulled down in the C’s, distorting the arching of the central area of the front which didn’t just affect the look of it but had quite a negative impact on the sound.
