I have spent the last few days in the workshop working out how to make this jig.. and have it durable and repeatable and totally accurate and easy to use.
Actually this jig can be used for two different projects … well probably more that two but thats all I have used it for so far.
To start, I had to build a table to go over the bandsaw table for the jig to pivot on. [double pivot actually][two pivots two pics right!! ]
The table was made from 5/8” [15mm] plywood, with silver ash used to hold the ply table to the metal table from underneath with various cleats. I wrapped the front and sides with some Purple Heart because I can,.
.,HI Kent.
The rear cleat system is removable to enable the table to slide on and the the rear cleat is then re.attached [Incra Build It Knobs come in handy for so many things,]to hold the ply table down.
There is also a front cleat to hold the front of the table to the bandsaw table. The table is removable from the bandsaw for many reasons ,. mainly so I can use the other jigs I have for it.
Bearings were inserted to make the pivot points. These points were centred 9.5” from the blade on a line at the leading edge of the blade…. [ This was done to enable me to use the template from the the spiral jig.}
This is fairly straight forward.. lol… not really… I didn’t realize that the pivot points must be perpendicular to the blade [ I actually knew this but didn’t do it anyway] . [OK all of you Jocks who want to see my mistakes .. this was one very big one…If you don’t have this right the blade will try to drift sideways and eventually jam or break ] You will notice the plugs in the table where the bearings were originally inserted.
This is all you get this time.. next will be the actual jig..
PS for those who have not yet had the pleasure of meeting my grandson Malakai.,. included is a picture taken at Easter when he spent a few days with us.

Thanks for the post, Larry. This is an interesting series so keep ‘em coming.
That is a wonderful picture too, by the way, of Malakai. This one needs to be framed and on display in your home.

hello larry ;
sorry about the confusion in my blog , with the pivot centers .
i just used nails and had to move them when i discovered the problem in my first attempt too.
i should have been clearer ,
mine was crudely built , but yours shows the refined crafstman that you are .
i like that you seek out the solutions and overcome them in a profesional way !
congradtulations with your grandson Malakai it must make you feel very good .
i am recently a grandfather too , but my son wont talkwith me as it apears that he was told i was dead many years ago, and he evidently is mad at me that i am not .
but maybe time will heal these wounds ?

Is the pivot center lined up with the cutting edge of the blade?
It doesn’t seem so by your pictures and if not, why?
I’m thinking yes but trying to save me a “plug” in my jig. ;-)

Thanks one and all.
David I hope it all works out well for you.
Bob you had it nailed but I like that you are willing to ask questions to ensure you have the correct knowledge. Just the angle of the pics but in the 4th pic the table in not set all the way and the blade is back from the line a fraction, when the table is tight then the blade is nearer the line.,. Give or take a few thou!
Paul he brings a smile to my face everyday.

Beautiful Jig. Nice Pic’s and explanation too. You and david must be engineers…
So how long before Incra or somebody else steals it and sells it in aluminum? You know theyre watching jocks like you and David for the next idea to market. Does anyone know how to extrude figured aluminum?
-- Keith, Bolingbrook, Illinois. How did you do that? I just started with a bunch of wood and cut away anything that's not part of the finished piece...

I am just a guy who likes to think a little differently to many others…... I nearly went to University to become an Engineer but I didn’t like trains so I said NO. Maybe Incra or someone else will .. I don’t know.. good luck to them.. I am still having fun… And thank you for your comments.. they mean a lot to me.
