HELP: V-nailing Double Bevels VS Single Bevels

Hello!

Recently we have been faced with a problem while ordering our frames/stretcher bars.
We keep asking for single beveled frames and keep getting double bevels. Our machine. "Pro Joiner Model F300-2". Is not able to keep the bars level on the machine because there is no grove on the metal.
I'm wondering if we can rig it to work some how or if we need to just buy a whole new v-nailer.... Does anyone build their own double bevel frames? Do you have a v-nail machine? If so, which one do you recommend?

All of the advise would be greatly appreciated....

Not sure what you are describing or asking about because of non-standard terminology.
What do you mean by "single beveled frames" and "double bevels"?
Also, what do you mean by, "not able to keep the bars level on the machine because there is no grove on the metal.?

Can you post photos?

Your stretcher bar molding has two "lips", or whatever that raised edge is called. It looks like you are turning stretcher bars into strainers, by joining them. Don't know why you would want to join them, when they've got tenons already, and can be manually assembled.

But if you really want to glue and join them, build a jig to slip under the raised sections of each piece, then nail away.

Those are not intended to be joined in that manner. No glue is used. They are not V-nailed.
The overlapping/sliding joint is designed to accept wedges in the slots on the inside of the frame that will allow the tensioning of the canvas after stretching. The wedges work by being driven into the slots forcing the joint open slightly.
The stretcher is fitted together and often a temporary gusset plate (I make them from mat board scraps) is stapled to the flat surface of the stretcher, inside the raised bead, to hold them square while stretching the canvas.
If you want fixed corners, the term for the sub-frame is a strainer. Adjustable sub-frames are stretchers. Strainers are available in length or chop, just like regular frames. there are strainers available for stretching canvas, and those used to strengthen a frame. The one used for stretching will have a single beveled profile and are designed to be joined with a V-nailer or other traditional methods.
