Framing box canvas

Post by KraftKool »

A quick update - we have the 3 key pieces of equipment now, morso, Cassese 88 and Keencut Ultimat gold.
We are busy practicing and despairing of ever getting it right :head: Just when we think things are improving something happens to completely throw us. I liken it to learning to drive - far to many things to think about and do with your hands and feet. Please tell me one day it will all drop into place.

We're doing the one day course at Lion tomorrow as a starter to our training. Hopefully that will make things clearer.

In the meantime what is the best way to attach a box canvas to L shape floater moulding? Out of all the practice pieces this one came out really good so I dont want to spoil it messing about with fixings.
Thanks

Hi KK.

4 small screws though the back is as good method as any. On really large scale stuff, making the holes in the frame bigger than needed and using a washer on the screw gives a bit of expansion room between the stretchers and frame.

As prospero said and you can also incorporate spacers between the canvas and frame to adjust the height of the canvas in the frame. If there is a gap between the frame and canvas I use strips of foam core as a spacer while fixing the frame in place making sure you get an even gap all round without having to measure.

Good Luck and just keep going the next one will be easier.

Thanks guys
My next question was how do you get an even gap all around :)

In this case you need to think inside the box.

Another option for affixing the stretched canvas is to use hook-and-loop fasteners, also known as Velcro. Staple the hook part to the floater frame, and staple the loop part to the back of the stretcher bars (or vice-versa) and just pop it in the floater. Easily removable in the future and gives you more flexibility in positioning it to begin with. Do not try to rely on adhesive to hold the hook-and-loop. If it won't hold on a corner sample, it won't hold a canvas.

I just logged on to check old postings on setting a canvas within an L-shaped frame and saw this posting, good timing :clap: I got a couple of bigger canvases brought in yesterday, I persuaded the customer that it would look nice in a modern black L-shaped moulding (REMB/0001 from Simons) . The depth of this is 23mm, I'm now thinking about what stretcher bars to use, the LION cataogue recommends using the Standard stretcher bars that are only 20mm deep when using with their equivalent moulding L1221 which is also 23mm deep. The canvas size is 125 x 95cm so quite big but standard stretcher bars don't have the option for a brace bar which means I'd probably go for the Premium stretcher bar which are 24mm deep and by the time they are fixed in place the surface of the canvas would be protruding about 5mm above the lip of the L-shaped moulding. Is that a problem ? Just wondering what everyone else does.

I was also wondering if it's that important to use 'proper' stretcher bars with wedges if the canvas is only going to be screwed into place within the L-shaped moulding ?? I'd prefer to use lengths of stretcher moulding cut to size. Just curious :)
thanks is advance,

Hi Adam

I don't think it matters as such if the canvas is above the frame it's more if its looks OK. I generally prefer to have the edge of the frame level with the face of the canvas. If you don't like the canvas protruding can you find another moulding, bet it's more expensive!

For a canvas that size you really need to use proper bars, with braces, to adjust the tension, not so critical with small canvases but something this size you could get significant variations in the tensions. Prospero had the solution for adjusting the tension once in the frame - drill the hole in the frame over size and fit a washer, you can then slacken the screw adjust the tension and lock the screw.

Rather than using an L profile you can also fabricate a frame using a rectangular strip of wood or turn a deep moulding upside down and use the back at the front, this gives a small lip (rebate) at the back for attaching a backing board or further strips of wood.

Never simple is it.

David.

Hi Adam
The canvas I framed is only 12in square so I can't comment on the stretcher problem.
The moulding I used was Lion L 1222 and as the canvas is 35mm I turned the moulding so that the bottom became the sides. Now this edge was unfinished so I sanded it flat, spray painted the sides matt black 6 or 7 times then sprayed the whole thing once. You end up with a band of wood grain around the sides and smooth faces elsewhere. The canvas is level with the moulding. I'm pleased with the end result.
Of course you could use barefaced moulding to start with.

Lion sell canvas offests in a huge range of depths. They are by far the easiest option for framing a canvas and work with most mouldings. :D
