Sliding Lid Box

  Usually I make a prototype of an project that I plan to refine for sale later.  I this case I borrowed an idea from Woodworkingformeremortals.com , thanks Steve.  I think he got the idea from somewhere too.  There is not much new in woodworking projects, boxes have been around for a long time.  

   In this case I figured to make a pencil box. If it turned out perfect I could put it in the shop to sell, if not, I have lots of pencils that could use a new home.

  I was working to the same idea as in the photo but was looking to make something a little more individual. When I was a kid I had a pencil box similar to the one in the photo.
  
love my clamps, Bessey clamps too.


  As you expect I didn't do it exactly the same way as the video, does anyone follow the instruction 100%?

  My old scroll saw ( a new General would be nice) is worn out so I decided to drill out the majority for the box and then clean out the left over material with a chisel.  Sawing the waste material out would certainly be much quicker and more efficient. Next box I will try cutting the inside out with my jig saw.  I made the inner part of the box from soft wood so I glued hardwood sides onto the box. You see it clamped up and drying.

The 14 degree dovetail bit made the angle for the sliding lid, using one bit for both cuts means that the fit is exact.  I did find that I had to use a plane to thin the top down just a bit to get it to slide nicely. I felt more confident in taking a whisker of wood off with a plane than resetting the router table and trying again.

  The final result is pretty good.  I would not try and round the ends again, too difficult to get perfect symmetry.  You can also see a couple of glue spots on the side where I didn't clean it up well enough before staining.  That was just because I knew this item wasn't leaving the basement shop any time soon.

   As a prototype I am fairly pleased, it clearly has issues but they are cosmetic so easily fixed next time. .  The advantage of making a test run is that ideas can be tried out and abandoned or modified for future production.  I like using the soft wood for the inside, it is easy to work and easy to sand smooth.  If need be I could prepare a few blanks and cut them out on the scroll saws at the Seniors Centre.  I like the finish and the oak makes a sturdy though thin lid.

   I'll keep you posted when I make another box.

Depth Measuring Gauge


  Lately I have been working on a couple of relief carvings at the Wednesday morning group.  I have re-discovered my love of this type of carving and am working hard to improve my skills.  Part of the challenge of relief carving is deciding which level various figures in the craving will be and then making sure the levels are consistent.  On a smaller carving I tend toward a maximum of four different levels and usually only three.  The back ground is carved away and I try and have it smooth and level all the way around.  I then decide what should be in the foreground and then try to balance the carving by making some aspects of the picture lower down than the featured item.  For example this carving is a Calla Lilly, the blossom with be the highest,(featured) and then will be leaves at two levels then the background level.




    I am sure that a great artist is able to do all their carving and levelling by eye.  I am not a  great artist, but I aspire to improve as a craftsman.  To make sure that all the various levels   are carved to equal depth regardless of where they appear in the carving I decided I needed some mechanical help.


    The edge is easy.  I make a mark around the edge of the wood and work the  material away until it is even.  Gauging whether I am equally deep into the wood when in the middle of the carving is a much trickier.
 
of course it is red, it is an Ian built jig.

  To make is possible to accurately know whether I had carved away enough material in the middle of the piece I made this depth setting/measuring gauge.


  The gauge straddles the work piece, then I screw the eye bolt down until it just touches the work piece.  I can then check all the sections on level two, or level three against one another.  If the gauge's feet sit flat on the bench while resting on the work piece, the depth is correct.  I haven't bothered with an incremental measurements on this gauge, because the actually measurement are not important, it is the relative/comparative measurements that are important. 

   As a tool this was very to make.  I drilled a slightly undersized hole in the cross piece and screwed the bolt through.  The nut is not really necessary, it just happened to be handy so I set into the cross piece too.  As you can see the eye bolt is much heavier duty than is required but it was was laying around purposeless in my tool box. Instead of going out to buy a bolt, I used what was at hand. 

   

  I glued the legs on rather than screwed, nailed etc.  I have many good clamps and plenty of good glue.  If there are no medal fasteners in projects connected with craving there are no medal fasteners for you chisels to hit.  Yes, I can't imagine any reason that a chisel would be near this gauge, but.....the precedent of no nails near carving tools is a good one.

Cheers, Ian W
