Lazy Susan..the making of?

This will definitely be a work in progress and will take a while so bear with me.

This is all very alien to me.

In this blog? I will endeavour to show some jigs I have built to cut and sand perfect circles.

Tool of Choice Is the Bandsaw. While circles can be cut with a router and trammel I find the bandsaw is far quicker. the Jig Is basically an extention table with a sliding dovetail dohicky for adjusting the different radii for larger or smaller circles. I will be making some Lazy Larrys…similar to Susans but made by me…Larry. When I have edge glued some boards into the size required I will set up the cutting jig and hopefully attach some big pics for you all to see. Unfortunately not really ready right now so will have to wait.

Blogs like this which detail a particular construction technique or jig development are always well received. I am looking forward to seeing some more info on this.

By the way becoming comfortable with posting here is a lot like hand cutting dovetails- practice, practice, practice. You are off to a good start!!

About to start

This weekend I have 5 days off from work so will be starting the Lazy Larry. The timber I have chosen for this is Queensland Maple. I am Dressing a couple of 1×8 s this afternoon and will biscuit join them although this is not really necessary for structural integrity. [ Long grain to long grain] but as an aid to aligning the boards thereby reducing the amount of time required for sanding. I am thinking that size does matter so will be making this one about 27 inches diameter. I am including a teaser. One pic of the JIG. Stand by. As you can see well used!

OK, I'll move on to the next installment. Thanks for the picture. The jig looks interesting. The hold down looks similar to the one that I use for securing my mortiser and bench grinder to the counter when pull them out of storage to use them.

Jig Pics

Here are a few of the pics of the JIG I promised. sorry bout the size, camera settings are skewwiff







Notice the Dovetail Slide, all cut from one piece. at the end closest to the bandsaw is a 5/16 bolt to use as a pivot and another bolt in a T-nut to secure the slide when you have adjusted the blank to the blade.
You drill a matching hole in the centre of your square blank. mount it on the bolt and spin through the bandsaw blade,. sorry if this is a bit sloppy. and I hope you can make some sort of sense out of it all


T

well next time a few of the Jig in action cutting circles.

Yup thats a big jig but it,s better than being too small! Nice and simple, gets the job done. Caboolture,s a nice part of the world by the way. Hope I didn,t wake you on sunday mornings when I was fanging my big Ducati thru there on the way to Maleny!

Laminating the blank

THIS IS OUT OF ORDER SORRY
Should have been part 4 not 5

Got the Maple dressed yesterday and started the lamination process.
I decided a thin accent of purpleheart was the go.. I love the purpleheart .. very few people in Oz using the purpleheart…so used the Incra fence to slice 1/16 inch strips to slip inbetween the maple [ I think the ever so small stripe will highlight the shimmer of the maple.]
So first I glued the PH to the Maple with Titebond II and used bluetape to secure while it dried… the purpleheart is purple on the first board but brown on the cut pieces..[purpleheart will oxidise back to purple with exposure to light]



Then glued up and clamped the pieces and waiting for the glue to dry [ decided not to use bicuits as the pieces fitted well and no slip]


Notice the alternating clamps . so the force is exerted uniformly across the boards and minimum cupping occurs.
Next step drill a partial hole [but not all the way through] on the under side of the blank in the centre [for the bolt on the Jig.] and then after sanding the blank, a quick spin and voile a circle is born. Coming Soon to a bandsaw near you!

Using the jigs

Hello boys and girls welcome!

Straight to it. The jig and how to use it.



After drilling the partial hole place hole on bolt and adjust the sliding dovetail dohicky until the blank touches the Blade and lock it off. Turn on dust collection and the bandsaw and spin the blank through the blade
Notice the purpleheart has oxidised back to violet.





and then on to the disc sander jig to remove the bandsaw marks { same principal as the BS jig]



How good does the final Lazy Larry Top look with some oil finish.





Next the base and how to attach the bearing, stay tuned

Same bat time same bat channel.

Regards Larry

Larry, the top look great. The purpleheart accents contrast nicely with the maple. This is going to be a nice piece when it is completed. Looking forward to the next installment.

Finished

Finally finished it..

Lots of other things happening in my world at the moment. So will post the last step
.

After attaching the bearing to the base insert a bolt 3/8" in to the centre hole of the base and locate it in the top underneath,.,using the access hole line up and drive screws though the holes to attach the base to the top/.
Just a matter of finishing the top…tung Oil finish for me.,

This concludes this blog.. thank you all for reading it… If you have any requests for a how to blog give me a shout..?

New cutting and sanding jigs ...

With the big clean up and purchase of new equipment, I decided that the old ratty jigs had to go… and I have now built both a cutting jig and a sanding jig…
Started with some Melamine… and then cut a dado in some Camphor for the sides… this will also help support the material…
Wood Flooring Floor Motor vehicle Automotive design


Tire Light Automotive tire Motor vehicle Tread


The lower part of the sides wraps around the table on the Bandsaw… and on the Disc Sander… using t-nuts and star knobs I attached cleats under the table to hold it in place…
Wood Gas Engineering Machine Machine tool


Wood Art Machine Gas Creative arts


The material to be cut and sanded it placed on a bolt inserted into a sliding dovetail… another t-nut and star knob are use to hold the sliding centre in place [from underneath].
Turning the star knob pushes the centre up against the two side capturing pieces…
Wood Shade Building Wall Beam


The material is then turned on the bolt… very quick, very simple…
Wood Gas Engineering Machine Electrical wiring

This jig can accommodate circles up to 800 mm… or 32 inches… in diameter..
The sanding jig uses the same principle…
Wood Tableware Kitchen utensil Hardwood Wood stain


I noticed on the original sanding jig that the circle was sanded on one part of the sandpaper only… so I made the centre slider wider to enable me to insert to bolt at alternative positions to use all the paper…
Next on the list, a Patron Jig and a Curve Cutting Jig..
Any questions or comments… feel free…

Arc cutting like Patron does.

Due to the fact that some of my boards have curves ends … I need to make another jig… this one for cutting arcs… to start with I need to decide how the arc would look… so a test jig was made…

Hole were drilled at various places so the jig can pivot on the bolt in the centre part of the circle cutting jig….. a fence attached and then the distance from the pin to the blade was adjusted to see how the different curves would look..


After several test cuts at different positions and distances…. I found 2 that I liked… I then took accurate measurements of these dimensions and will now make the jig for regular use…

How it works...

I think that a short video explains things better than a lot of words… so I made this on my i-Phone. I apologise ahead of time for taking this one handed… but as you can see the jig can be operated safely with one hand on a camera..although it is certainly easier with two hands and no camera….

While I was cutting one arc… well I made a few more boards…


As you can see a teaser for the next project idea…


One for the beer drinkers and one for the recyclers…Keep them out of land fill….The bottle caps that is…..
