Firstly I must thank Spencer for sharing his knowledge and instructions for using the scroll saw to produce this Mobius Ribbon. It took a few attempts before I succeeded in achieving a Mobius worth showing. This method definitely out does the multiple segment ribbons I have previously shown. Cutting with the scroll saw at 45 degrees has to be accurate to achieve the final join up but I have done it and joined an elite group who have.
I used Marine Plywood, sanded to 400 grit and finished with 3 layers of Danish Oil. The Mobius is sitting on a piece of Red Gum root.
I have finished some other ribbons using the scroll saw and will post later.

Nice job. I like the creative stand…I hope it holds the Mobius Ribbon securely(!)

Malcom Tibbets gets credit for showing us the mobius ribbon construct…but as far as I know, Bob’s is only the second one on the planet to be made using the scroll saw and using a process that shares only the resulting Mobius Ribbon shape with Mr. Tibbets’ works of art.

Awesome, Bob! Trying to wrap my brain around this, how thick is your starting piece of ply? Any particular reason for using the marine grade? Looking forward to more! Thanks for sharing.

Bob, showing off in his most unusual way. That’s a compliment. Like I say God’s showing off with a lovely sunset. You remember Ziggy, the cartoon guy, who used to stand and applaud sunsets? I applaud thee, Bob Of The Twirlie Things.

Just by looking at this I can tell it’s not done easily. Your persistence and patience must be a virtue. I bow my head and tip my hat on this one Bob. Beautiful.

Wowie you’ve outdone yourself here Bob, this is a really tricky piece to get right, I know from turning my ribbon balls there is no room for error in order to get that match up. I love the stand to show it off :)
Exceptionally well done Mate

cheers
Pete

You haven’t mentioned a size ?

Thanks for the comments, this was a great challenge to complete successfully. 2nd on the planet eh Spencer? You didn’t say who was first? Candy, the ply is 1/2” thick, I find Marine ply is free of flaws and much better quality.
XquierflyX, have a look at Malcolm Tibbets gallery on the net and work from there. Pete I’ll measure it up and ley you know.

Man, that is WONDERFUL. Great execution and finish.
I suppose you made this one and the others in a couple of hours, NOT!!!!!!!!!
Many hours in your shed and a fantastic result.
I love it.

Bob.

Hi Bob

Another master piece, you are a very patient man, a project like that would drive me over the edge pretty dammed quick LOL
I wish you could send me about 10 degrees of your heat it would sure make -17 C look a lot nicer
take care
Bruce

G’day Bob.. A Masterpiece for sure. At first I thought Picture 3 was my favourite. Buit the more I Zoom the entire set of pictures there is lots of appeal in each shot. You have certainly worked hard to strive for this result.
Congratulations Bob. Very well done. Great finish too, the Danish Oil and that quality Ply is a good combination.

The Red Gum Root is Perfect!!!!

Regards,

Cliff.

Bob,
Specifying the scroll saw method used as the distinguishing factor, I think I was the first on the planet and you are the second. You are a good student with the diligence and determination to get it done. It is definitely NOT a typical scroll saw project.

Everyone else,
A LOT of credit has to go to Malcom Tibbetts for showing the possibilities to do this in wood. Then credit to the rest of the woodworking community-at-large because the method I created incorporates a circle-cutting jig as used on band saws and ported over to the scroll saw with my own modifications… and that was in order to incorporate a variation on the method used to make bowls on the scroll saw first published by Patrick Spielman and Carl Roehl and later by Carol Rothman…plus some ingenious glue-up methods that I came up with by necessity cuz there’s no way to clamp the parts. (“Necessity is the Mother of Invention”... besides the glue-up methods, the truth is I couldn’t do it the Tibbetts way because I don’t have a lathe.)

It can be done in any wood, but plywood shows best because the ply lines accentuate all the curves (the higher the quality of plywood the better). Our visual results using plywood cannot be duplicated using the Tibbetts/lathe bowl method. The resulting shapes are the same but the differences in construction are significantly different (staves vs ring segments).

I showed my mobius on LJ in 2012: http://lumberjocks.com/projects/68961
Other projects I did using this technique are here:
http://lumberjocks.com/projects/65803
http://lumberjocks.com/projects/65825
http://lumberjocks.com/projects/68982

Malcom Tibbetts is the true king of these ribbons-from-bowl-parts type of projects. His are sooooo much more complex.

Thanks for the addition Spencer, there was a lot of interest in 2012 on your site but not much follow up action.
4 years later an Aussie produces, thanks for the tuition. Agree with you on Malcolm Tibbetts I have tried his way and know which I now prefer.
