A bit late on guitar updates

I’ve been really bad at keeping this up to date.  There are probably about 15 posts I could make at this point, but I’ll keep it short and post a pictoral update.

I actually made a test guitar body to try a few things out.  I’ll skip all that stuff and move to the real guitars.

For these two, I wanted to try laminated linings, made of basswood and walnut in this case.  After one other attempt in laminating right on the guitar form, I made some simple fixtures and roped them together.  This worked really well.

These will be my first cutaways.  The sides were thicknessed, primarily with the drum sander, then switching to a scraper.  The bass side was a simple bending operation.  The treble side was a bit more complicated.  I bent the waist and lower bout, then cut the side at the start of the cutaway and bent the remainder in reverse.  All this to get a good match on the wood grain and ambrosia stripe.

The match was good enough that I decided to try to miter the point and skip binding it.  Worst case is if it didn’t turn out, I could resort to binding.

Mitered the tip.

Came out nicely.  I even wrapped the side over the neck block, simply because I didn’t decide on a final style for the heel yet.

Back to the linings.  Rather than just radius the inside corner, I had a scratch stock that I made.  I used it to dress the profile.  Came out well and probably didn’t take any longer than a simple radius.

Finished rim.  Minus soundport.

The tops and backs were joined.

The bracing was split and prepped.

I did a fairly tight radius on the backs.  This led to a rather unorthodox clamping method, both for the changing radii and for a quick glue up with hot hide glue,

Trial fixture.

Better final fixture.

I also made all the binding from raw wood as well as the rosette.

Here is the binding.

And purfling.

I’ll make a separate post on the rosette.

Thats about it for now.  Short post for a lot of work.

Starting a couple more guitars

After a brief hiatus and doing a bunch of small projects for the shop and in the house, I decided to start a couple more guitars.  On the subject of shop projects, I should post those soon.  I just haven’t felt much like writing these days.

So… the guitars.  Going for a couple OO size again.  This time with a cutaway, 14 fret neck, one with a spruce top, one with cedar.  Other options might be a sound port and a slotted peghead.

Start with design.  I wanted to make my own shape.  Started with a list of standard dimensions from OO and OM size guitars and drew my own.  Used the bent stick method of drawing curves.

IMG_9107

Made about 4 versions and picked one I liked.  I did a full scale drawing and I’m still kicking around what I want to do for bracing.

I made the form.

As far as wood goes, I bought a board of ambrosia maple that had some nice flame in it.  I marked off the pieces that I wanted and resawed it to size.  Finally got to use my new bandsaw for something heavy duty, and it worked like a champ.  I cut a total of 4 sets from this board.

There are also some orphan (non book matched) pieces, as I was able to get 5 slices from the thickness.  I will make a test guitar box with those so i can play with some new things Ive been thinking about, as well as some brace options. Here are the two sets I’ll use for these guitars.

As far as the rest of the wood goes, I laid it all out.  Cherry for necks.  Basswood for neck and heel blocks as well as linings.  Walnut, cherry and maple for binding, purfling and rosette.  Of course the ambrosia back and sides.

Looking at all of this, I realized that minus the cedar and spruce, which is from British Columbia, the rest of the wood is local.  That being the case, I may go for a local wood for the fretboards and bridges.  It would be cool for the majority of these guitars to be made from materials that came from within a 50 mile radius.

Ok.  More for next time.

 

I never worry, but I have started to fret.

IMG_7830

Started fretting the guitars.  I have two done so far.  These were my first bound fretboards so I had to clip the tang off the fret to go over the binding.  I made a little device based on one I had seen, with some modifications.  I call it the Detanginator.  Worked really well to grind off the tang and dress the bottom.

All the guitars have been oiled and sealed with shellac.

One more to fret.  Then to build, locate and mask off the bridges.  Then I should be close to spraying lacquer.  That should be interesting as a first.

 

Working my way towards a finish

Masked off the two flamed maple guitars for stain.  Opposite color schemes for these.

IMG_7739

Used a homemade walnut stain I made last fall.  Dark back and sides on one, dark bindings on the other.

IMG_7786

 

Added a couple coats of boiled linseed oil/turpentine mix to help accent the figure, careful to mask off the top and neck.

I have the neck on the third guitar, but I’m not happy with how it seated.  I may remove it and reset it.  I guess I’ll get a bit of experience steaming apart a neck joint.  Hope to get that done soon and the neck back on with a nicer fit.

Then on to shellac sealing, fretting, bridge making and the lacquer finish.

Well that’s enough of these for now.

Finished the binding and end graft on all three.  Just did some minor variations on the ends.  The cherry guitar got rosewood trim.  The end on that one is a bit busy, but I think the contrast will tone down … Continue reading

This is the end… graft.

End graft

Its a bit different than most, but I wanted to connect the rosewood purfling lines on the front and back.   I used a strip in the center of the end graft to make the connection, rather than continuing the binding all the way around, as in a traditional binding scheme.  Used a razor saw, chisel and router plane to excavate the the end channel.  I’d have to imagine I was done before I could have devised a fixture to route it.  One of the reasons I love hand tools… the binding ledges are a different story.

The first OO is all bound.  Scraped down the bindings and purfling.  Still need to sand everything.  The scheme I had in mind was to mirror the rosette color scheme.  Pretty happy with how it came out.  Overall there were very few gaps.  The gaps on my first guitar(s) were bigger and virtually disappeared after a bit of work on the finish, to the point where I can barely see them (believe me, I know exactly there they are).

Working on the second flamed maple guitar.  I’ll probably do the same thing?  Sometimes I change things in process.  Not sure what I’ll do on the third yet, but I have some ideas.
