Topic tags/keywords: clamp rack multiple frame clamp miter saw joining

I have come onto a new project that requires me to do something in quantity that I have need of advice for… hopefully this knowledgable group can help.

The project will require me to make picture frame like designs in quantities of about 20 to 100 per day.

I really dont have the money (until I sell some of this stuff) to go out and buy huge amounts of clamps.

The frames will later be reinforced, but mostly what will hold it together before then is the glue and a brad nail or two per corner.

I searched all over the internet and on the lumberjocks site, but all I get is racks to hold clamps.

I have some thoughts on something to build for it, but ultimately keep finding reasons it wont work in the end.

Any suggestions you might have would be appreciated. Please let me know if you have any questions.

Make a jig and square up your pieces glue and nail. Do it assembly line fashion.

Make up some cam like clamps out of good maple(the shape of the cam looks like a coma) use a base of mdf or plywood,set up a square corner,and use the cam clamps for the remaining two sides.Could even use a couple of stops internally to prevent pushing piece to far in.
hope this helps.

Tigarman,

Perhaps you got on the wrong train of thought. Never tried this myself, but have thought about it. My usage really makes the cost prohibitive, as I just do small hobby stuff.

There might be more here or elsewhere on the web about this ‘titebond hipurformer.’

Just another idea, personally I cant imagine doing 100 of anything in a given day, attention deficit.

Maybe these help?

I’d figure a way to avoid clamping with the process if that many are happening every day.

Consider the wisdom of “just a couple of brads to hold it while the glue dries” that we’ve all heard a million times whilst oogling Norm’s shop.

Seriously, can you brad or staple it together?

I don’t know what you are doing, but maybe a set of fixtures that you can affix the work to with cheap rubber bands or inner tube elastic bands?

Thanks for the tips!

I just ordered the Titebond Hipurformer.

Hopefully it will live up to my expectations!

FWIW…

I had an early model of the HiPur system; didn’t like it, the glue was expensive, and didn’t keep. For a finish carpenter doing crown mould, yeah, but I couldn’t get a tight cabinetmaker joint with it.

If your corners are mitered, I think you’re going to find trying to put a pin in a corner very frustrating and not very helpful.

I would recommend as many of these as you can afford.

I have about 8 of them, and when I am doing quantities of frames, I cut some pieces, glue them (no mechanical fasteners) with Titebond and let them sit oh, 20 minutes or so, unband the oldest one and do another. I can cycle through them pretty fast and these clamps will get the corners nice and tight with no exploding incidents provided your miters are accurate.

Kindly,

Lee

Packing tape… watch Doug Stowe make box corners with it.

We had to make a good many frames once and what I did to rig it up was build a clamp frame with angle iron and clamping cylinders to hold the frame square during assembly. You could also use wood and the push/pull clamps. i rigged up a jig with a biscuit jointer to cut the slots and then we got one of the 23 gauge pin nailers.
The idea was that you would put the glue in the parts and assemble the frames and clamp them. Then we would shoot the pins from the back side into each corner of frame and into the biscuits. There would be four biscuits per corner and this locked everything in place. With two frames it went pretty fast because that would give you a little more setting time. Three would work even better but these clamp tables are easily built. They’re very much like the ready made face frame clamp tables are.
