Conceptualizing my pedestal stand/table

[SwampDonkey]

Just a joke Dodgy concerning Bob's previous post about his table and his shy clients.

I'd take the table, before the house mortgage on that luxury home. ;)

Sorry, I can't explain it any better.  ;D

[WDH]

SD, I say go for six legs .  That will be a real challenge :D.

[Dodgy Loner]

Gotcha, SD.  You're making more sense now ;)

[metalspinner]

SD,
On a table the size of  pigman's MT is definately the way to go.  A small end table can get away with sliding dovetails.  Another method to get a good fit of the turned foot to dovetailed shoulder is to shape the shoulders of the tails to the circumferance of the post.  Dogey Loner's method is certainly easier, though.

Pigman,
That is a beautiful table.  I don't like to stain wood, either.  Especially to match production cabinets. :  Why do people think all there wood stuff needs to be the same color?  Can't we enjoy the natural beauty of wood?  If not, why not just paint it white? :-\

You guys expect too much of me.  :-\

[SwampDonkey]

One thing is for sure....


There isn't any way that you can bread board 4 sides with 45° cuts on the ends of the bread boards, one edge is gonna have to be square cornered at each end.  I suppose you could cheat and just dowel that edge on, making sure to cut the dowels on the end grain for strength. ;)

I have seen plans for a Shaker pedestal stand like this. It had three legs and used a sliding dovetail as was mentioned. It also used a metal plate on the bottom to resist splaying of the legs. I will try to find the plans, as I think I have a copy.

Bump!!!

Going to work on Monday. ;D

I figured out another method that the bottom of the column can be round. The top will be square that attaches to the table top. So simple.  ;D

[SwampDonkey]

Ok, let's see here.



Each side of the table is going to be 30", without the 1" edging around the table. So, let's see if I have this right. Half the width is 15", which is the apex of the diamond, in other words the walnut triangles on the corners are 15" along the edge of the table. So, I want to find how wide the base of the walnut triangle is that fits the edge of the ash diamond centre, in other words the width of the ash section in the middle.

C² = A² + B²

C = sqroot (A² + B²)

C = sqroot (15² + 15²)

C = sqroot (225 + 225)

C = sqroot(450)

C=  21.21 " or round to 21.25"

look right?  :

15" x 15" x 21.25" for each walnut triangle and 21.25" square for the ash section?

Ok, so how many 6" wide walnut for the triangle?

Need to find the height of the triangle.

B² = C² - A²
B = sqroot (C² - A²)
B = sqroot (15² - 10.625²)
B = sqroot (225 - 112.89062)
B = sqroot(112.10938)
B = 10.588 or 10-5/8" rounded

so two boards will do the trick

I turned the pedestal from a piece of NB cherry today. I don't know how stable it will remain, but it's been drying for about 10 years in the barn. ;D There is a gum pocket as you will see in the before pic. I couldn't quite get it all turned out, but I'll try filling it. There might end up being a couple fine checks that may not show up. It's not a perfect piece of wood, but I'm going to try to make it work.

Before




After



Here is what I came up with. The square end on the left will mount to the top and the rounded end on the bottom is where the legs go. Yup, there is about 4 inches on the bottom which will be cut off on the band saw. I have not sanded the thing yet. Kind of timid around a 6 x 6 cant spinning at me at 2000 rpm while I was shaving her down.  ;D

[TexasTimbers]

Looking good so far. ;D

I just read the whole thread, not every word but pretty much every post. I never did see hwere you finalized on how your leg joinery.

[SwampDonkey]

The new concept will unfold as we progress along. ;D ;)

One thing I realized about the trig math. I'm sure it's a rule or identity of some sort. If you have a triangle with 90 - 45 - 45 the height is half the base (the longest side opposite the 90).  ;)

[Tom]

I'm going to stand outside and look through the window while you do this.  It scares me.  The last time I saw a page with stuff like that on it, it was describing the end of WWII. :D

[TexasTimbers]

yeah i with you Tom that kinda math looks like something that was snuck out of Skunkworks Stealth Lab or maybe an Area 51 reverse engineering paper.

[Furby]

Would that mean you are a peeping Tom ???

[SwampDonkey]

Might not have the same wham effect, but she's heavy.  ;D

[Tom]

Have been all of my life.  ;D

[SwampDonkey]

Anyone need some staircase banisters turned while I'm the business?  ;D

[Furby]

Tom:  ;)

Sure SD, I could use enough for one set of stairs.

[WDH]

Looking good.  Keep it coming............

[SwampDonkey]

Well, just as I had expected the cant was not stable enough and is checking. The real reason is there is some pith that I couldn't quite plane out. I still think the turning is useful for something and have it placed over by the stove to dry and see what becomes of it. I sure ain't gonna burn it unless it flies all apart or something.  ;D

So now the plan is to laminate some 2 x 6 cherry. $7 a board foot later....and I have enough to turn 3 pedestals if I so wish. I'm thinking of another table project and it will be 6 sided with all kinds of wood pieces all mixed in the top. That's for a later date.  ;)

[SwampDonkey]

Nothing new to report, just letting the glue set between the first two thirds of the laminate. Will glue up the last piece tomorrow and let cure a few days before turning a new pedestal for the table.  I see some nice gum pockets in the cherry, mostly micro sized stuff. ;)

[WDH]

Will add to the character......

[SwampDonkey]

Well I'm by no means an expert at lamination and this is my first lamination project. Now we are talking 2 x 6" timbers here, about 46" long. Black cherry.



Here the first two layers have been glued and clamped 24 hrs and drying near my stove. I had 4 clamps on this work piece. One on each end and two in the middle.



Here I am applying the adhesive, Weldbond, to the laminates with a paint brush. Any excess glue that oozes out between the layers I remove with wet sponge and water. It's quite a mess so I keep cardboard on top of my workbench table saw.  ;)

Now I will let the whole thing cure for 3 days before venturing on.  ;D

[metalspinner]

That first one was good practice, SD. ;)

Waiting for that glue to dry is a killer, ain't it?
