My Chair Maker's Bottoming Iron

The term 'Bottoming Iron' was used for a curved Shave for taking out the Adze marks on Windsor seats.

R.A. Salaman, Dictionary of Woodworking Tools, 1989




I have an order to make a close copy of a 1930 Santos Hernandez guitar and since its plantilla, or outline, is a little different than the one used by Antonio Torres, another solera, or workboard, is needed to build this guitar. Once the top is glued to the neck, all the work done to assemble the guitar will be done on this work board.

The soleras that I use are scooped out to create a dish so that when the braces are glued onto the guitar's top the braces will hold that arch once the glue dries. A domed top gives a guitar a real voice, one that has volume and lyricism.





I usually use a curved bottom plane to hog out most of the material, but this time I pulled out a "travisher" that I made quite a few years ago, back when I thought I could make some extra money selling Welsh stick chairs.





I bought the blade from Country Workshops, and I followed the instructions for making a chair bottoming iron that is in Drew Langsner's great book, The Chairmaker's Workshop. The book is still available but Country Workshops no longer carries any kind of curved spokeshave blades.





The body was sawn from a chunk of maple that I purchased from Loren at the Wood Emporium in Loveland, Colorado...





The blade is held in place with just a few washers and screws.

I've never had the blade come lose or change position while working with it.






I re-shaped the area in front of the mouth and it works even better than it did when I first made it 17 years ago.

The dish on the work board is completed, I just need to give the pieces a bunch of coats of shellac, as much as the MDF will hold, to help stabilize the material. How I make a work board will be another posting.

Merry Christmas, everyone!

Off the Bench and For Sale: Miguel Rodriguez Style Guitar

This guitar has a Western Red Cedar top, Claro walnut back and sides, Royal ebony fretboard, Indian rosewood bridge and a 650mm string length.

This guitar has a beautiful voice and is loud! I was amazed at how loud it is as soon as I got the strings on and tuned to concert pitch. It is easy to play and I am blown away by the musical nuances that can be created with this guitar.

I made this guitar several years ago, but because of custom orders, I had to set it aside. I put strings on it two weeks ago and it is a most magnificent sounding guitar! It has good, clear separation string to string, wonderful sustain with evenness and balance throughout with a very lyrical voice. I originally made this guitar for myself, but someone with a good strong technique and a good understanding of musical interpretation should own this guitar and play it on a regular basis.



This guitar is a fairly close copy of a guitar made by Hernandez y Aguado in 1961. The body length is 480mm, most of the HyA guitars had a body length of 490mm; string length is 650mm, many were 655mm and longer; other than that I trie…

Late Summer, Early Fall and a Spruce/Ziricote Classical Guitar

Thus begins what many residents feel is the Southern Rockies' most beautiful time of the year - Indian summer.

It is sunny today with bluebird skies highlighting the golds and oranges of the aspen trees.

Fog covered our little hollow all day yesterday, the sun came out at exactly 4:45pm and shone upon us for fifteen minutes, then the clouds came back.



The aspens and ferns in the backyard...



A few wildflowers are blooming, like this harebell...


Our little flower garden is going to seed...



I dropped six ponderosa pine on our property last week for firewood and fire mitigation, as you can see I have much work to do splitting and stacking the firewood.


This is the latest guitar on the bench, a 1961 Hernandez y Aguado style guitar, with a Colorado Engelmann spruce top...
