Title: Making a world globe
Post by: malc on January 16, 2011, 11:12:34 am
I am looking at ways to make a world globe about 12 -18 inches diameter and am racking my brains how to make the sphere. i would like a hollow one if possible and don't have a lathe so am looking at scrolling one. The land masses are no problem as I will scroll them from very thin ply 1/32 or 1/64. But the sphere has me scratching my head, any ideas. P.S. thanks to everyone who showed interest in my wooden clock.
Malc :)

The first thing I thought of was "geodesic domes". I googled it and came up with some info on them....too much to go into here but, I'm sure you could get some ideas and help by doing that.

check this one:

might be a system you can use. Dark wood for the water, brighter wood for land?

Malc,  A couple of years ago, there was a puzzle maker on the cover of one of the scrollsaw magazines.  I don't remember if it was Scrollsaw or Creative woodworks and crafts.  He had a picture of a round wooden jigsaw puzzle.  I will try to find that copy and get his name etc.

Like Julief said, I remember seeing one somewhere, but I can't remember where, I did find this link on a globe puzzle, it may give you a better idea how they are done. It is a puzzle for sale.

Why not use the same method as making a bowl tilt your saw at the desired angle ! and cut the rings, then just glue the 2 bowls together.......Paul ;D

It was on the cover of SSW&C Issue 31 (Summer 2008).  Tom Stewart was the Grand Prize Winner 2007 with his "Art Ball Puzzle".  It is impressive and the article says that he used a router in a "machine" of his on creation to carve the outside and inside curves.

I just ordered and received the back issue assortment from SSW&C, this was one of the back issues.  I have spent the last few days going through the magazines and coming up with ideas on things to do.  They list an email address www.artspacelima.com for info.  The address is to an art display, of which the ball is a part, so I don't know if the address is still good.

Yes Paul, I think that will be the best way. I need to read up on bowl making. Not sure how to smooth the sphere without a lathe and how thick to cut the rings.

you can also bend thin plywood. or use veneer in multiple layers, glued to the form you need. How about an inner frame? You could leave the sea out and make it "see-through"...

lots of space for ideas.

@ HWPlmbr1
...at least he still needs a predefined plan for this  ;D

OK, Malc.  The double bowl idea is probably going to be your best bet.  To round and sand it, use an inflatable sander for the inside and I would chuck the rest in my drillpress and use turners sandpaper strips to make the outside prefectly round.  The bowl is cut in consecutive rings and glued up.  There is a perfect example of this in a book by Carole Rothman called Wooden Bowls for the Scroll Saw. (page 113)

Pipe fitters have a method of making end caps called the "orange peel ", after you lay it out on wood, you would have to steam the wood to make it pliable enough the bend. But this may work.

Hi Malc, you may be able to get your angles from this, might work !!!!!....Paul
Title: Re: Making a world globe
Post by: tux_linux on January 27, 2011, 07:46:41 am
hmm, that needs a lot of angled cuts - or a lot of serious sanding.

Another idea:
I posted a link to a moresque lamp @ instructables.

How about changing the way the pattern is connected? One can build a double layered globe with overlapping edges, which can be connected subsurface.

Torsten

The fellow with the ball puzzle at he scroll saw expo. told me he had to make the tool that he built the puzzle with, he did not elaborate but I believe it involved a router as well as a scroll saw. he had it set up at the saw expo in 2008 I think. check  out issue 31 of scrollsaw woodworking and crafts

Malc

Some people make hollow balls or globes by paper mache over a baloon as the form. Toy baloons available everywhere even the local supermarket. After the layup dries who cares if the baloon deflates.
You can add several layers to increase the strength, it will also be light. You could also use a cheap ball often found in markets too. My wife buys them for a buck or so for her dogs to play with. Also light weight.
The lay ups would give you something to glue your pieces to also.
