        when gluing parts to make a picture frame I’ve seen numerous artists on youtube use painters tape, or masking tape to hold the parts in place while they dry. Others use all sorts of clamps, straps, elaborate devices to truss up a frame.

        The tape seems to work just as well. These artists routinely sell framed paintings made this way… so why does anyone still use clamps?

            I’ve used my Brad nailer and compressor for 20 years…..quick and easy.
            For that long ago small investment I’ve framed hundreds of paintings.
            I’m not sure I would trust tape to hold really tight joints.

                With modern wood glues, my understanding is that for the strongest joint there needs to be some compression applied until the glue sets. Based on the joining I have done with and without compression, that seems to play out. Pressure also helps close up any gaps.

                Hm. I haven’t heard of using tape but it seems like it wouldn’t hold it very tight and also sort of wasteful. Why use tape that you have to throw away over and over again rather than just clamp it with a corner clamp or using a strap? Straps work great as long as your profile isn’t too crazy. I have a hard time joining swan type frames but other than that clamps/straps are the way to go imo.

                    I was once fortunate enough to have watched a truly professional framer put a frame together for a few minutes, while I was waiting for something else.

                    He had cut the 45 degree miter, and using some sort of a vise-like contraption, also set at 45 degrees, he smeared some sort of glue on the raw edges of the angled ends, and brought them together in a tight fit, using this vise device.

                    I was amazed when he unclamped the assembly only a few seconds later, displaying a totally cured, and dried glue joint! To this day, I often marvel at such a feat of efficiency, and I wonder just what sort of glue he must have used so many years ago.

                    The “clamping time” for this glue was a matter of seconds,…..not minutes, or hours.

                        Most likely a cyanoacrylate, known by its scientific name as super glue.

                        I use brads from a nail gun to hold my frames in place while the glue dries – like Derek.

                        I was just surprised to see someone (and I’ve seen others on youtube) use tape instead of clamps or brads. This guy, in particular, makes twenty plus frames at a time and is a full time working artist – and also worked for several years as a carpenter. So?? I don’t know what to think – evidently it works.

                            I have never heard of using tape to hold corners together during drying time.

                            I use an underpinner or ”V” nailer in conjunction with wood glue specifically for end grain timber joining – brand name – ‘Aquadhere’ – Available in supermarkets & hardware stores.

                            For synthetic mouldings I use the super glue.

                            I prefer the underpinner to a nail gun/compressor as the joining is from the base not the side.

                            Joining from the side means ugly nail holes which have to be filled later using the appropriate colored clay putty – Extra work & slightly less professional IMO.

                            The underpinner has the extra advantage of being able to ride ”V” nails on top of each other ideally for thicker mouldings.

                            When the corners are clamped & nails go in, the glue dries quickly both for timber & synthetic mouldings.

                            Hope that helps.

                                    I am a frame maker and I have used everything from tape to glue to under-pinners to staplers and nails and finally via the simple expedient of holding the mitered edges together by placing a heavy weight on top of each corner. Whatever is likely to work while producing the best finished look to the joint based on the width, thickness, height, and profile of the moulding is what I will use.

                                    What I am saying is that there is nothing wrong with simply taping the mitered edges together as long as you can get the edges together sans any gaps.

                                    If you are going to stick with the tape method then my recommendation is that you use both tape and a heavy weight on top of each corner until the glue has had time to set. This combination should give you the best results. I hope this suggestion helps.

                                        I have all the gadgets for framing: clamps, bands,t squares, etc but once I learned the tape trick I’m never going back.

                                            Speaking as a woodworker the tape method would work. In fact for those worried about the amount of compression. I’ve seen a lot of instances of things being clamped too tight causing most of the glue to seep out and leading to a weak joint.
                                            My method of choice would be clamping or nailing.

                                            I wonder just what sort of glue he must have used so many years ago.

                                            it depends on how long the glue was on before clamping but I’ve used forms of contact cement in woodwork at times.
