Dickinson Portland Guitar February Shop Updates with Videos and Process Pictures!
Hello Acoustic Guitar Forum!
This thread is going to be the home for shop updates, videos and pictures of various acoustic builds in process. All the stuff that’s unrelated to custom builds. We have three acoustic guitars in process right now. An OM koa, OM Bolivian rosewood with Adirondack Spruce and OM flamed maple with spruce. The first two are waiting to be finished so I made a video comparing the tap tones of the two. There are two versions the first is a short one with only taps. The second has more commentary and explanation. And the long one: Next are pictures of a few of the different things going on in the shop. Here is the polish we’re doing for a friends guitar. It’s in between spray coats right now.  His guitar is another Fisherman theme. This time there are fish around the rosette and a fish on a reel on the head stock.  The nut for this neck is one of our newer split nut designs that allows for the nut positions to be changed for each string  Moving on to the maple guitar. This one was started very recently so it’s in the beginning stages of life. Here is the back put together. I think the ebony back strip adds good contrast.  These are the sides in the bending process  At the last step for today is gluing the curfing into the sides. This is done while the sides are in the mold  Thank You for getting this far! I'll be updating this thread through the month so check back. --Jay and Max Dickinson

Thanks Pete!
We're very excited for the seminar. I'm planning to record some practice sessions of the different parts for myself. If any of them turn out, they'll show up here!

Here's a clip of our cnc routing out the heel block of one of our neck blanks. We had already done the top and back of the neck but our cnc isnt tall enough to finish while doing the back. The neck is mounted to a special jig that's keyed to the center of the machine. It can then be flipped on it's sides to finish off the heel of the neck.

Hello again!
Here is a little update. First is the top of the new maple guitar. It is Adirondack spruce. The rosette is made from pieces of our exotic scrap wood and the inlay is a powdered plastic/rock mix  The next thing I have is a little deconstruction of our split saddle bridges. I made these images in preparation for a university seminar and though they might go well here First is the deconstructed view of our bridge. There are three groups of pieces. The bridge, saddle plates and the bone saddles. The saddles sit on the plates which sit in the bridge  The individual saddles have a spring in them which prevents them from moving when the string is off  The saddle plates have a similar spring in them which prevents them from falling out with the strings are off.  Together these pieces create our adjustable split saddle bridges

First is a demonstration of intonation errors at the 12th fret using an imitation bass guitar.
By using a strobe tuner and a simple bass guitar, which has a nut, fretboard, bridge and strings with the saddles and nuts adjustable, we are able to see that an E at the 12th fret when uncompensated is sharp. When the compensation is applied it plays more or less in tune. For a real setup it would be nudged until exact. The australian pair Gore and Gilet in Build and Design explain this setup in thier intonation section. They suggest using it to imitate a guitar in order to find the compensation needed to chisel the nut and saddle. Here are more pictures of the maple guitar being built The top of the maple guitar with the rosette  The back with braces  Glueing in the end grain support flange  Glueing the braces to the top, using the go-box
