Picture frame stand - second one

Ok, so I have not made much apart from bee hives and also time limited.

Play the music for the show .............

Project – Picture frame stand

Wife asked me a couple of months (maybe years?) ago to make her some picture stands for some small paintings that were given to her by friends when we moved.

I envisaged something with hinges and fold out legs, and that just blanked out my thought process.

Roll on to our first Wednesday tea in July 2023.
2 Of the residents were going to do a flower arranging demonstration with a lucky draw. Wife was off to physio and I was delegated to attend. (it is also a social get together of the husbands in the back corner of the hall.)

Being the first lucky number to be drawn I had a choice of arrangements to pick from.
Collecting it I noticed that they had placed a painting on a stand which looked like no hinges.

I walked over to the one resident house and borrowed the stand which turned out to be in 2 pieces (triangles) with one slotting into the other one. The lady paints and she stands her canvas on this stand.

Moving forward (faster than normal) I drew the triangles in 1:1 scale with all the measurements.
Then looked at what timber was available. Found a piece of Meranti 60mm wide 1200mm long and thickness varied between 10mm and 20mm.

Once fed through the thicknesser, the table saw cut 3 lengths, which went back the thicknesser to trim to same dimensions.
Now the cut stock is not enough for the frame.
Onto CAD-Excel – draw shape with dimensions.
Then calculate a re-size to 80%, 75%, 70%, 60% determining how much timber would be required for each size.
The 75% would do just fine leaving a small offcut.



The corner angles were measured and the base corners were 70 ͦ to be cut at 35, which left the top at 40 to be cut at 20.

For small thin bits like this I would not attempt the RAS or table saw.
They will be cut by hand using a very fine hacksaw blade.
The corners will all be joined using 3mm dowels (read 3mm bamboo skewers)

The corners turned out ok requiring some tweaking with a Stanley blade and sand paper.

Drilling the holes for the dowels required serious clamping down of the frame and accurate drilling. Then gluing and knocking in the dowels.

The 2 cross pieces were cut and the angles measured to the frame.
First assembly test = CARP. Had to unscrew and break the glue. Not too much damage.
A bit of clamping and fiddling around and they were ok.





Some light sanding, 2 coats of Woodoc 10.

The 2 frames



Assembled



Here is the stand being used with a small painting



And the back



The size of the stand is just right for the size of the frame.

The picture frame is landscape view 335mm x 285mm

The stand needs to be sized to suit the picture stand.

As I don’t use CAD I will see what I can do in my Excel sheet.

The other picture and frame is larger and a portrait view.

Cunning!
Excel should do all your scaling for you once you have expressed the key dimensions in trigonometric terms.
Unless you are making wildly different sized stands, fixed timber cross sections should be fine.

Thanks Bob.

"trigonometric terms" :shock:

The last time I was exposed to that was in the early 60's in high school.

Very neat Phil.
I cant quite see how the two triangles slot together without the vertical one falling over.

Just so happens that eldest daughter needs something similar as she is not allowed to make holes in the wall of her rented flat.

Andy, have a look at the large triangle.
You will see 2 cross pieces, 1 front and 1 back.
The gap between the 2 is 2mm wider than the small triangle thickness.
The small triangle slots in between and rests on the front crossbeam and as the main triangle lies back it wedges the small triangle.
Very sturdy.





The small stick out bit is to stop the frame from slipping

If that has confused you even more, let me know

Here is a pic from the original stand. View from the back.

Thanks Phil, I think I’ve got it now. The horizontal triangle fits inside the vertical one. So the points of contact on the ground are the base of the vertical triangle and the tip of the horizontal .
Any chance of a photo from the side?

Ok, found some more of the original, see if that make more sense.

 

[AndyP]

Thanks Phil,
Understand it now.

I wonder if the near horizontal triangle needs to be that deep

To be stable it only needs to be a bit further back than the centre of gravity of the picture.

The small triangle pushed all the way back is very stable as it wedges in on the large one with enough wood for the picture frame.

I might give it a try when I can find some spare scrap.

that is very elegant phil! looks great.

Second stand

Not wanting to start another thread, so just tag onto this one.

The first picture stand turned out good and useful and when that was completed I cut and planed some Pine for a second stand. First one is on the dining table with photo of the kids.

While shifting some offcuts the Pine popped out and I found the full scale A3 drawing.
The sawing template for the angles was also in the offcuts box. I started cutting the corners with the large hacksaw used last time, no good. Tried the smaller one, no good. Wobbly cuts.

So ended up cutting on the scroll saw. Not quite 100% but ok with a bit of sanding.
All corners cut and checking layout on plan drawing.

.

Then started the glue up, lots of clamps to keep it in place.
The corners then received a 3mm dowel just to ensure they don’t come loose.




After that came the cross pieces which keeps the smaller triangle in place. Took some time and patience to get the gaps right and then glued & screwed.

The stand would be painted as Pine is very dull (managerial decision) with an off white spray paint.

However ………… The test fitting revealed that the inner triangle did not go back far enough and the stand was unstable.

This was not the FUF visiting but plain stupidity when planing the strips. The strips were 4mm too wide.

Big decision time:

Do I remake the small triangle? No, not enough cut and planed timber left.

Do I just cut up the whole lot and bin it? No.

Third option is to just trim off some of the edge on both sides. Mark 2mm each side, draw cut line. Now approach the RAS. Extremely dangerous cutting process as there is not enough support against the fence and cutting with the grain (60 tooth blade).

After cutting the fit was ok, the cuts needed some sanding of 150 Grit.

Under coating, oil based.





Note the ‘nails bed’ to lift them up.

Spray painting was 3 coats both side.

It looks ok and in use.
