Best selling wood projects - Making A Boat Paddle Tenor Ukulele Part 5 Catching Up

Best selling wood projects

Best selling wood projects


Oh my, where has all this time disappeared to?
So much to do around here and the ukulele build has been on the back-burner.
Our home is a large log cabin construction with a fully painted exterior.  The LOML, in her spring cleaning mode, started an outside spruce-up that turned into a full exterior house clean. A huge job!

We last painted the exterior in 1996-97..............
You can see whats coming...............  Now that it is clean lets re-paint, she said.  OK, I replied.  I really love painting .............. hahaha

 (this male king parrot landed on my painting trestle)

Soooooo ........... guess what has occupied my leisure hours of late - we have been painting, and painting and painting ...............

Oh, there was also the rehearsals for the concert by the Tele Point Ukes and Singers.......................

.............and the concert itself..................

trips to Young.................

.............. and Sydney - and my sons engagement to wonderful Edwina .............

........the party ..............

........... gardening .........

................. lots of gardening .........

...... babysitting ............... lots of babysitting ............

............ end of year parties and wrap-up dinners, as well as.........
..........school concerts .................

(......everybody was Kung-Fu fighting ......................)

.................. and woodwork........... well, bits and pieces.
I have found some time to cut and shape the gusset blocks for the ukulele body as well as lay out the fretboard and make a start on the neck.
Ill get back to that in my next post.

Soooooo ........ we are back up to speed.
 Every blessing to you and yours for this season of Xmouse.
May you find some peace...... and in doing so, add a little more joy to the world.

Best selling wood projects - Making A Boat Paddle Tenor Ukulele Part 6 Sides Front and Back

Best selling wood projects

Best selling wood projects


Okey-dokey, some time in the shed at last and getting back on track.

Sides
The moulded sides are well and truly dried and are holding their shape quite nicely.
The cutaway section is in two parts and needs some re-inforcing gussets to prevent chipping and to strengthen the joins.  I have chosen a couple of pieces of African blackwood, both for strength and because it matches both the fretboard and the headstock.


These two gussets will be glued in place before the linings are added to the inside.

Here is a view from the inside.


This end block will become the corner of the block that houses the neck.  It will be made from cedar for lightness and strength.
Ill cut a block from this piece of Australian cedar and I will also shape the mortice in it before gluing.  This so much easier to do while the cedar piece is long - it is also safer when using a router.


Gluing Up the Front and Back

The front and the back are made from book-matched thin (2mm) pieces of mango.
Before gluing, each piece has to have its glue-edge perfectly straight.  I do this with a plane on a shooting board.
This timber is not mango, but black wattle - but you get the idea.

The edge-trued pieces are glued together and held in place under tension by nothing more than masking tape.


A flat surface is placed on top to keep the drying skins from warping and this is held down with a small weight.

The finished results are shown with the mango skins dried and flat.


The skin on the left will be the front and that on the right will be the back.

 This skin is most highly figured of the two, and will look best on the back where it will be able to show off its lovely grain to advantage.
The other will have a sound hole cut into it as well as a bridge glued on top.


Finally I have cut some strips from what was left of the mango used for cutting the sides.  These strips will be used for bracing and strengthening pieces on the backs of the front and back skins.

Next time Ill work on the neck.

Best selling wood projects - A Commission Ukulele Interruptus

Best selling wood projects

Best selling wood projects


Been away ....................... back again - and itching to get on with the tenor ukulele build.
However ......................
.............a project for a client has interrupted the music of uke building for the moment.

Re-shaping the World -
A Desktop Globe With A Wooden Frame



Here it is - (well it is very similar, I have dismantled the one Im working on) - a desktop earth globe, whose metal and plastic frame is to be replaced by one made from Australian rosewood.  This has exercised my creative cortex for a while now, and I have finally come up with a solution that is both simple and practical.


The main part of this construction is the equatorial ring that supports the globe, and is in turn supported by the legs.  Rough cutting the internal circle left some spokeshave work to do, to get it smooth.
I love rosewood, it is so easy to work, and soooo forgiving.  Planing around the flat edges of this circle meant that there would be many times when I was planing against the grain - and across it.  I started with my Millers Falls number 6, but soon had to reach for a smaller plane.  Those shavings in the background are all from that process - gorgeous!


A small low angle block plane handled this easily.  This is the little Lie Nielsen violin makers plane that I bought for the ukulele build, and it is perfect here.


For the lower circle that will brace the legs, I had to rip down to thickness from a suitably sized block of rosewood.  It could have been planed to thickness, but I wanted to keep the scrap ripping for ukulele parts.  In planing, all that is produced is shavings, where - by ripping - I can salvage some timber for later use.
Here, the Millers Falls squares the edge before I start on the table saw.

After running each edge over the tablesaw blade, I finished off with my Tyzack Nonpariel 6 point ripsaw.  Ripping to thickness by hand is not one of my favourite pastimes, but this saw really sings - and it is as close to a pleasure as ripping can get when I use it.  A truly beautiful saw is this one.

It might be Nonpariel, but it did a good job of cutting parallel in this case - heh, heh!  (my kids hate my jokes!)

As you can see, I marked the circle on the wrong face (or I ripped the wrong face - take your pick) - easy fixed though.

The lower, smaller ring gets the same treatment as the upper ring, and there is plenty of work using the round bottomed spokeshave.  This is the Veritas model, but there are plenty of others equally as good.  Because the shave must go with the grain, and the grain changes so often in a circle, the workpiece had to be re-positioned in the vice many times over the course of this smoothing.

The legs are my own design, and are meant to complement the curves found everywhere else on this globe stand.  They will stand wider than the original model for added stability.

Trial fitting before glue-up.  Trusty 4 inch Silex square to the rescue.
The legs are fitted to the top ring with dowels and secured to the bottom ring with brass screws. No these arent brass - Im still waiting for them to arrive.


Glue-up time.  Glue-up takes place with everything in position so that there are no regrets when it dries.  The lower ring (top one in this view) can still be removed after the glue dries, but provides the tension and the bracing for the legs at the moment.

A coat or two of finish - and were done.



Now - lets have a crack at the soundboard for that tenor ukulele ..................
Bring it on .................!

Best selling wood projects - Making A Boat Paddle Tenor Ukulele Part 4 Sides Bending and Fixing in Place

Best selling wood projects

Best selling wood projects


Bending the Sides to Shape

I use a small bending iron and an atomiser spray.
 
 

The heat from the iron and the sprayed on water act to steam the timber making it soft and pliable.


 Mango is surprisingly easy to bend and it took far less time than the sassafrass of my first uke.

Assembly


The scrap pieces that were cut from the mould now come into play as clamps - holding the sides until dry.


I have positioned the end block in place with a mark down its centre line to keep it correctly positioned.  This will later be glued and clamped.


The waste-clamps are expanded by using nothing more than an expanding toggle, normally used for tensioning wire.  The top shaping blocks are forced apart with nothing more than a simple wedge - see below.

The end block is made from a small piece of Australian cedar - light but strong and with good acoustic properties.  It has been radiused to the same curve as the body at this point.


The two sides meet at the bottom of the body and are held in place by the glued end block.  As you can see, the two sides dont quite meet at the centre line.  I stressed about this in my first uke for a day or more but was never able to establish a clean middle join.
I dont worry about it now, and after the glue dries I will cut a wedge shape exactly in the middle and insert a decorative piece of African blackwood as a feature.


These two pieces will meet at a corner - a potential weak point in the body.  I have decided to strengthen the corner and eliminate the weak join with a small gusset that will also show through as a feature.  African blackwood again. This will come a little later.


Ill glue in the end blocks one at a time. Here, the bottom end block is glued into place.  The top block will come later on and it will have a mortice cut into it to house the tenon on the end of the neck.
Things are taking shape nicely.

Best selling wood projects - Building a Hall Table Part 2

Best selling wood projects

Best selling wood projects


Commenced last post and progressing quickly.
Here is the piece of the slab that I have chosen for the top.



It has a natural edge for much of one side, and I propose to make this the leading edge, with the other long edge against the wall.


It will be held in place by buttons - these have been sawn from a scrap piece of camphor laurel, and will allow the table-top to move seasonally with wet and dry weather.





The finished and assembled table frame.  The legs are tapered on the insides and straight on their two outside faces.  This adds a look of some elegance - to my eye anyway :) .

Sanding through all grades of grit from 100 to 400 before a series finishing coats is applied.


Happy shavings to all.
