Use V-Nails : pro-like !
When the edges of a frame are debited, it remains only to stick the edges and to join these edges before tightening them with a band clamp... The modern wood glues are very resistant and this collage is enough the most of the time, especially since frames hung on the wall do not undergo mechanical constraints !!!
V-Nails or staples for frames
V-Nails or staples for framesMost of the time, frame studs glued with a good wood glue and kept tight during the drying process will give you a solid frame without the need for staples .
But if you want to be sure of the look of your frames, you have to secure them with metal clips called V-NAILS. Their shape is "V" and they firmly join the sides of the frame...
They are fixed by the back of the frame and join by tightening the two angles at 45 ° of the moldings ... In the photo, there is only one V-Nails of posed ... one generally places 2 ...
If you have never posed a V-Nails, take a look at this page ora demo in picturesawaits you ...

Simply to tryYou can use V-Nails to join yours frames without having any tool... just V-Nails and a hammer !
It's not a great idea but andcan assist youin the event of problems...
The installation of V-Nails assumes a tool that holds the stapple in place while it is inserted into the wood ... And this tool can be cheap or downright expensive depending on the use you want to make:
I found you some of them:
This model Rockler is particularly practical : you can use it to push manually the v-vail ou you can hit with a hammer...
See this special page:tutorial to assemble a frame... for a picture demo of the use of V-nails.
It consists of a tool to drive V-NAILS staples, with a small stock of staples and especially a vice at 90 ° to keep the uprights together during the installation of V-NAILS.
The V-NAILS tool is rudimentary but effective, it is used exclusively with the hammer while the moldings are well maintained in the vise delivered with.
Note this lot ofV-nails at great prices!
For a photo exhibition, club framing, semi-pro work ... I recommend a mechanical assembler, more expensive of course, but more efficient and much more convenient to use ...
ROCKLER V-nail installation tool 
If you have a lot of frames to build... 
For a perfect use : first glue the ends of the frame-bars and clamp them. Wait for complete drying. Second : keep the band clamp in place and put now the V Nails (V-nails are only to prevent the frame breaks after a fall...)
If you often have frames to build... Then you have to be efficient and equip yourself properly! Why not a "Pneumatic Picture Framing Nailer". It's a good investment in terms of value for money and you won't regret it!
Several models are available: I recommend this one which has already proven itself and whose price is reasonable: you have a small place for it in your workshop !!!
It is a robust and powerful tool. You will be able to safely drive many V-Nails without any problem. The work is clean and easy (look at the picture board below) .
The only problem is that a source of compressed air is required to operate it. I looked for an electric and autonomous V-Nail gun but I didn't find one.
Bonne fabrication!
