Best selling wood projects - Building a Ukulele Part 7 Body Assembly

Best selling wood projects

Best selling wood projects


The various parts are sloooooowly coming together - a right shoulder injury is hampering my activities mightily at the moment.  It is taaaking .... sooo ...... looong to get the smallest tasks completed.

Serendipitously, it gives me an even greater appreciation of the courage and abilities of the competing para-olympians.  I really admire those athletes! Two weeks to go - bring it on!

OK, here are the bits.
Lets have a go at putting things together.


The body has had an embellishment added to the toe - in the form of the same burl veneer as the headboard.  Two reasons for this - to tart it up a bit, and provide a little balance in the design - and the second reason is to cover a badly matched join where the two sides met.


By making it wedge shaped, the filler piece can be cut oversize, slid into place and glued - then the top and bottom trimmed off.  Looks OK I think.

Ill be fitting the back first, so the back linings are attached.

Linings for the back are glued in place - hooray for clothes pegs!


Here are the back linings after drying.
Ill have to attach the neck before the top goes on, to give me room to clamp the neck tenon in place.

Ill fit and glue the back next, as the design of my neck means it has to be attached from the top, and the fretboard over the top of the soundboard.  Do these later.

I hoped to have more done than this, but ...... life intervenes .............
.... the shoulder, doc - the shoulder ...................owwwch!

Until next time ................

Love life and live ..........

Best selling wood projects - Building a Ukulele Part 8 Neck Fretboard and Bridge

Best selling wood projects

Best selling wood projects


Righteeeooho - here we go ho ................
The neck glue-up passed without incident, and it is now ready to accept the fretboard.

The scale on my tenor ukulele is 17 inches.  This determines the distance between the edge of the nut and the peak (break line) of the saddle.

With the soundboard temporarily in place, I can measure for the position of the bridge that carries the saddle.  I do this before gluing the top onto the body, so that I have some room to clamp the bridge during its glue-up fitting.  Too hard to do this after the top is fixed to the body.



There will probably be glue squeeze out during this, so I mask off the area around the bridge with tape. This also acts as a good locator for the position of the bridge which is bound to slide around a bit on the glue.


Once done, the soundboard and bridge can be set aside to dry while I mark out the fretboard.


The positioning of the frets is critical, and the good folks over at Stewart MacDonald have provided a free-use fret position calculator - mucho gratias my friends.

Armed with a printout of my 17 inch scale for 18 frets, I am good to go.
These have to be marked on the squared fretboard before tapering it, so that the fret positions are easily done with a try square. It is more accurate to use a marking knife for the fret marking, as it minimises the inaccuracies of pencil thickness.



The fret positions should all be marked from the edge of the nut, and not marked in increments from the previous fret mark.  Doing it the second way only multiplies any inaccuracy with every fret mark.
So, the ruler is clamped to the fretboard and all marks laid out before scribing them.  I have carefully ticked off all the fret marks as I go, to ensure I didnt miss any.

 
Ill cut them next, before tapering the fretboard to suit the neck that I have already built.



Now, the fretwires themselves have a very narrow seat, and so a very narrow-kerfed bladed saw is needed.  I tried several of my saws, before finding that my Veritas dovetail saw is just about perfect - narrow kerf, and very little set on the teeth.  It is a rip saw of course, designed for cutting dovetails along the grain, but serves very nicely as a crosscut saw in this instance.


 To help with the saw cuts and to keep them on track, I made up a little square saw guide.
Works a treat.


Got to wait a little, while glue dries.
Next time, Ill attach the top - and after that sets, Ill fix the fretboard.
Nearly finished - yippee ....................
Still got some time left for some strummin practice -
Uke group night tonight - FUN!

Love life and live .........................

Best selling wood projects - Building a Ukulele Part 7A Body Assembly continued

Best selling wood projects

Yes, I know, glaciers move faster than this, yet things are happening.

Somewhere under all those clamps is the back of the ukulele attached to the body, which is held in the mould.  Use your imagination.

 

Here it is after the glue has dried - and before the edges are trimmed off.  As you can see, I have given the inside of the back a couple of coats of shellac to seal it. 
I will do the same for the inside of the top, and the interior of the body, before the top is fitted.  
I am hoping that by sealing both sides of the timber, I wont have as many issues with seasonal  timber movement.


Here is the back in all its glory - after trimming the edges.
Things are starting to look encouraging.


The linings for the top are attached in the same way as those on the bottom - good old clothes pegs!
Here, I am planing the linings level with the sides.  The top is flat, and I dont want any sticky-uppy bits in the lining to spoil it.
Some parts of the lining drifted upwards on the slipperiness of the glue before drying - no problem, easy fixed with the Lie Nielsen 101 small block plane.  This is such a good sized plane for this job, when even a regular block plane would be too large.


OK, the neck has to be fitted before the top goes on, so that I can get clamping room - to hold it while it dries.  The second reason is simply that the top gets glued over the heel block, and the neck tenon.
Here is a trial fitting.
That little piece of raised tenon has to be removed, while the neck is raised to the level of the finished top.  This is important, because the fretboard is glued on top of both - and they must be in the same plane.

Next step will be to glue the neck in position, before adding the top.
Starting to get exciting, isnt it!

Thats all for now, the glacier needs to rest.
Love life and live ...............

Best selling wood projects - Making A Boat Paddle Tenor Ukulele Part 8 Making and Fitting the Body Linings

Best selling wood projects

Best selling wood projects


The Hall Table is finished and gone to a good home.
Soooo - back to the Uke.

The body of the ukulele is complete as far as the sides go, but it needs a neck block.



I have made the neck block from Australian Cedar for its lightness, strength and tonal qualities.


The neck block is over large - as this end of the uke is a weak point on a cutaway design.
The neck block is glued in place.

I have been refining the body and getting things ready for the application of the linings.  These hold the top and bottom in place when they are glued to the body sides.
I made the linings on the tablesaw from a piece of paulonia.



The kerfed timber was then cut into strips on the bandsaw.


The full story of making the linings can be found here:
http://thevillagewoodworker.blogspot.com.au/2012/06/building-ukulele-part-1-timber.html
I had made enough when I constructed my first ukulele, to have sufficient for a few more ukes.
The linings are held in place by clamps and pegs until the glue is dry.

 

This is done one side at a time, to allow the mould to support the body, and for it to project enough to apply the clamps.


Once  the top is done, the mould is flipped over and the process repeated for the bottom.


Inevitably there is excess glue that needs cleaning up, as well as any bumps from the linings that project above the edges.
This is easily attended to with a small block plane.
Enough for today.
Next time Ill look at the front and the back.
Happy shavings to all.

Best selling wood projects - Building a Ukulele Part 9 Body Fretboard and Finish

Best selling wood projects

Best selling wood projects


Things are coming together nicely now.
The top is glued in place, and I have finished the trimming around the edges.


The body is assembled, the bridge attached and the fretboard taking shape and ready to glue to the neck.


Here is a trial fitting of the unformed fretboard before shaping.
 

Shaping is easily done with a block plane.  This is my Stanley number 18.


 Here it is after shaping, in a trial fitting.
I will finish the dot markers and fretwires before gluing this to the neck and body.


 In a moment of vanity, before the top was glued in place,  I decided to label my ukulele - and I have a notion of building more - so I gave myself a brand name - Riverside Ukuleles.
Seems appropriate for the Village of Telegraph Point, as we sit right beside the Wilson River.


After installing the mother of pearl dot markers and the side markers, the fretwires will be on and the fretboard ready to go.
I have found a very cheap and plentiful supply of side fret markers from the local markets - old knitting needles.  Just the right size and they can be cut to button length easily.


I am going to attempt a shellac finish on the soundboard and the body, and the old hands at the Hastings Woodworkers Guild tell me it will take many, many coats.

The western red cedar top is quite soft and needs hardening for protection, so I am hoping that the shellac finish will be appropriate.  Before this, I will tape the bridge and the end of the neck to protect them from over spatter, and fill the sound hole for the same reason.

Enough for the moment.
More next time .......

And happy woodworking to all ...........................

Best selling wood projects - School Holidays Grandchildren and Woodwork

Best selling wood projects

Best selling wood projects


Our grandkids came to stay for the last little while as their parents are both working.
Since LOML and I are retired, we score the munchkins every holidays.
Most regular things seem to come to a halt when the ankle biters arrive, but occasionally I get to take them to the shed for some woodworking time.

My eldest grandson is in high school, so a project that will challenge him and satisfy his creative muse will be different from that for the little-uns.

Ry had a crack at an end-grain cutting block for his mum for her kitchen, and Em had a go at making a simple box.

Here are some progress piccies.


Ry planing the edges of his creation.
Lie Nielsen Low angle jack plane.


Chamfering the edges with a low angle Millers Falls Block plane


Em - the essence of nailing concentration





I love working with my grandkids at the workshop.
They like it too.
Happy shavings to all

Best selling wood projects - Carter Australia Hand Planes A Small Review

Best selling wood projects

Best selling wood projects


I have been wanting to write some comments on Carter hand planes for some time, ever since I wrote about Falcon Popes.

Another vital part of Australias tool making history belongs to Carter Tools Pty Ltd Australia.
The building boom following World War 2, and the worldwide shortage of tools, led to the establishment of several Australian tool manufacturing companies.

Carter Tools Pty Ltd was a Sydney company that provided bench planes, G clamps, sash cramps, vices, hatchets, brass plumbobs, pipe cutters, bench screws, hand routers, vernier centre finders, and much other urgently needed tooling to a market hungry for them.  Only in business for a little over 20 years, Carters products came and went quickly.


Several Carter handplanes have come my way over the years, and it seems appropriate to give them a short review, as they still surface (heh heh) at markets and garage sales.

  One interesting aspect of Carter Hand Plane manufacturing, was the way that the company sub-contracted out the casting work to different foundries around the Sydney area.  Because of this, there are often differences in both shape and quality among Carter planes - even those of the same model.

Even the frog castings show differences in design - perhaps reflecting the variations from the different foundries.  The Number 06 fore plane at the top shows a different frog and base casting from the others.

All frogs have the looped lateral adjustment lever - a simple and effective design.
None of them have the frog fore and aft adjuster screw that was found on Stanley planes, and copied by both the Falcon Pope and Turner handplanes that were also made in Australia.  Just like Sargent hand planes in the United States, Carter decided that their planes didnt need them.
This simplified the castings for both frog and base.



Three of these planes have brass depth adjuster wheels, while the number 06 fore plane has an aluminium depth adjuster.

All handles are made from Australian hardwood - normally coachwood - and all are painted with black enamel.

The handle on the 4-1/2 has been through the wars, and has lost its spur - as well as showing a crack across the middle.  These wounds were not uncommon, given the tough lives that these tools often led.  Bouncing around in a tool box from one building site to the next, can cause damage and always takes a toll on appearance.


All have their original Carter blades except for the 4-1/2, which has one made by John Shaw of Sydney.


John Shaw produced plane blades, HSS tip bronzed to the main body of blade.  There isnt much left of this one, but a comparison with other similar blades shows how long it probably was when new.

Here are two blades with HSS tips bronzed to the main body.  The first was made by Titan and the second made by Stanley - probably after they took over the the Titan Manufacturing Co Pty Ltd.  Interestingly, only Stanley Australia seems to have made such blades, and not any other Stanley enterprise from any other country.  This makes me think that it was an Australia-only phenomenon - and one probably started by John Shaw and copied by Titan - to be continued by Stanley when they bought out Titan.

 The Carter blades are all much thicker than a standard Stanley blade, and all are very close to 3mm thick.  This is more than 30% thicker than the standard Stanley offering.

The reason for this is probably to be found in the design of the frog.  All Carter frog castings have support for the blade only at the very top, and the very bottom.

Compare that to the bedding for the blade provided by Falcon Pope and older Stanley frogs.  There is blade support there - all the way from the top to the bottom of the frog.



The thought occurs to me that the Carter design allows for less exactitude in casting, since only the top and bottom faces need machining to the one plane in order to bed the blade.  This would save time, and allow the frog castings from different foundries to be finished off with minimum grinding.  A simple solution to the obvious quality control issues attached to multiple castings from multiple foundries.

An ordinary thinner Stanley-type blade would likely experience induced chatter with a frog design like this.  The Carter blades, being so much thicker, resist this chatter and cut quite well - even with such a frog.  Of course, their extra thickness also makes them popular with woodworkers - as replacement blades in other makes of bench plane.

The bodies of the Carter planes are robust, and usually of thicker and heavier dimensions than the equivalent Stanley.

Comparing the cheek thickness of Carter number 5s and number 4-1/2s with those of a Stanley, the variations of Carters foundry castings are apparent.  The carter 4-1/2 is particularly odd, with one cheek significantly thinner than the other.


Here are two number 4 planes - one Carter, the other a Stanley.  The differences in length and thickness are obvious.  The Carter is significantly larger, even though it has the same width blade as the Stanley - 2 inches.


All of this translates into extra mass - the Carter is nearly a pound heavier.  It is also not as refined as the Stanley.  Here it is up close:

Surprisingly, it can still be set up to function as a tolerably good smoothing plane.  A sharp blade and a tight mouth can produce quite reasonable results.

Here is a piece of Australian rosewood that has first been dressed by a Carter number 5, followed by the Carter number 4 smoother.  The grain was swirling and in places a little tricky.  The Carters did a presentable job on it.

Apart from the minor tear-out shown, the remainder was glassy smooth.

Conclusions
Carter handplanes were made to fill a niche in the building industry, at a time when anything was better than nothing, and they were turned successfully to cabinetry as well.  In these tasks they performed creditably.  They are a mixed bunch, with some examples being very well made, and others a little rough and ready.  Time has moved on, and consistently better made examples of handplanes have appeared and become commonplace.

For all that, Carters are somewhat rarer than others, simply because they were manufactured for such a short time.  A good one is well worth having as a working tool in any workshop - others may only be added to collections as historical footnotes.

The blades are something else again.
I have never come across a bad one, and the extra thickness is appreciated by hand plane enthusiasts, and those who want good performance from their plane - no matter the brand.  If you get a chance to own a Carter blade - jump at it.

Are Carter planes worth buying?
Definitely!
It may end up being a good one - or - it may just be your little part of Australian toolmaking history.
Either way, the blade alone will be worth the purchase.
