Here is a repair on a guitar I bought from eBay. The guy selling it said his cat pushed it down the stairs.
I’m blogging this not so much to outline how this guitar can be saved but also to show you how Martin guitars are really stuck in the past with there construction and are they really worth the price tag.
You can see the ribs have been cracked beyond repair. My aim is to completely replace the ribs.
Remove ribs up to the blocks and kurfings.
Now we can see the bracing. This is the original 000 construction and is copied by many guitar makers. The struts are squarely cut and blocky. They are not finished smoothly as you would expect from a guitar that costs over £1100. (But I guess you are paying for American labour cost)
When I am making a steel strung guitar I use a strutting construction that allows more movement across the front. Still using ‘X’ bracing but not joined. Also using other techniques to excite the bass, middle and treble transfer. All internal areas are finished to a fine 1200 grade paper.
The guitar is put into a mould.
AAA grade mahogany ribs are selected and cut down to the thickness of the original ribs.
The ribs are bent to the mould.
Then the old ribs are completely removed.
Then new ribs fitted from the heel and clamped on.
Finally the ribs are finished.
