no previous part Part 1 of recurve series no next part

just wanted to thank all you lj’s for your encouragment and support .
this site has fullfilled a long time dream of mine ,
to get back to my artwork .

i work allot streetside , and it’s mostly that , work !
from cement , framing ,drywall , to roofing . some fun stuff at times .
i have been retired for 2 years now , but knowbody seems to know that ( especialy me ) .
mostly i am the lifeguard at the carpentry pool , when all the hot rods have been fired or quit ,
and the client is broke , that is when they call me . my job is to fix all the badly thought out
and poorly designed and built messes they have left .
and make everything look as if it was planed that way .
make it look as if i was never there !
i have been asked many times over the years how i did something ,
i explain and watch as their eyes glaze over ( they don’t even know what im talking about ,
and really don’t care , just being polite ).
even many that i have taught , have left the trade ( to much work ) .
.
so i say thank you to you all .
your interest has reinvigorated my love of my craft .
you have all shown me new ways of looking at things .
your works and enthusiasm is energyzing .
and the friendship is priceless !
her is a jig i made today after seeing larry’s ( degoose )lazy larry’s and his exellent jig he made some of them with .
this one is a double curve and i hope i have explained it to be of some use .
.

.the end product .

.this jig has 2 pivot points ,start with the jig to the left and #1 pivot , rotate jig to right until it hits the stop .
this cuts the top 1/2 curve .

.place pin in pivot#2 and remove #1pin , then move jig to left and cut 2nd curve .
retrace steps moving pins as apropriate .

.

.move part over to 2nd cut position and repeat all steps for all parts

the base has line across at blade front that is where the pivot pins go.
drill #1 pivot in both boards and cut until axis on slider is over line on base ,
then drill pivot #2 and pin removing pin #1 and cut almost to spreader on lower end.
put stop on side . screw top spreader board back on jig , it is now trapped by blade , but spreader boards hold it togethere . put stops where they will keep saw from cutting through ends.
the number of “rays ” you need to figure by drawing a star point and also by how wide your ” rays ” are .
i cut all but 2 and fitted them together and had to make last 2 a little wider to fill in the gap .
if i was to do this as larry does , i would make an adjustable part stop , and cut some scrap first to fine tune .
just keep moving the pins back and forth and the jig back and forth and keep your hands out of the way ,
and enjoy !
.
p.s.try to make your parts to be exact or to overlap a smidge , them you can cut accordingly instead of making
more wider parts . also use a piece of the test that you like to mark a recktangle so as to get 2 pieces out of it .
i just made this one out of some ply i had leftover from another project and guessed at size of blanks .
so i had wierd scraps left over .

David, I am thinking about putting a poster of you in my living room!
this is ingenious. It seems that the angle at the bottom would decide the number of rays (the angle between the two rectangles you marked) so if you mark carefully i think you should be able to have same width parts and no gaps. did you use the same jig for the top curve or is it just a simple pivot?

I also wonder if this jig can be easily changed to cut waves (repeat the process on the same board). this will make an amazing cutting boards with very little glue ups.

You are a genius David! I’m favoriting this one along with Larry’s jig. As Larry knows, I’m not the sharpest chisel in the shop when it comes to geometrical intelligence, but I will probably figure it all out after awhile. Thanks for a great blog and a great idea.

David fanastic as usual.. This will make a few people think and hopefully get the creative juice flowing..
I am tempted to go up to the shop now and make a start on this . but have 5 orders for the scalloped spiral and will have to get them out first but … next is the double spiral and the sunburst.
moshel.. that gives me another idea.. stand by,
Mike you get there in the end and have a heart of gold. Just hang in there, it will come in a flash and you will understand all.

I’ll need to study this when I’m back home. It reminds me of drawing an elipse with two centers (pivots or foci), a string and a pencil. Very creative.

Thanks for the post! Cool looking double curve and I believe I even understand the jig! I can’t wait to see how you and Larry modify the next generation of this pattern

The jig I am making does a double curve at 9.5 inch radii and total diameter of 20” with the 12 segments of the spiral LL. I am figuring on making a few [read a lot] so will be adapting the design to allow easier clamping and set up each and every time.

I really like this, but it’s going take this old geezer a little time to figure this out.

( you allready figured it out ) .
