Glue Bottles - What you Love or Hate

[Michael Kellough]

Corner Weld (by Framica) was formulated for miters, which is essentially end grain to end grain. But with an open time of one minute or less, not useful for most woodwork.

Framers, however, apply glue to one surface, put the two pieces in an underpinner and step on the pedal. Done. 10 minutes later the frame can be loaded with glass, art and backer. You could not do that with any of the Titebond products.

Fast forward to 0:50 to see how quickly miters are joined with an underpinner. Underpinned joints need glue though. Some Cinese imported picture frames try to get by with the V-nails only. It is not really acceptable. The underpinner I had was entirely manual, with the foot pedal providing all the pressure.

With your manual underpinner did the device have a stronger overarm clamp than is shown on this rig? Looks ok for a pneumatic pinner but maybe not for withstanding pressure for a longer time.

It was adequate for clamping. The mouldings never lifted while driving the v-nails.

I bought it used from a framer going out of business. It was not a premium machine. But much faster than cross nailing the corners, which I used to do.

By the way, if anyone wants to buy a used mat cutter, most framers retired theirs when they leased their CNC automatic mat cutter, but held onto it “just in case”. But the automatic cutters proved to be very reliable, and I do believe that many framers have forgotten how to use their manual machines.

Mailing out inquiries to all the area framers will likely get you offers on that and other framing equipment.

Note: My spell checker changed my correctly spelled “area framers” to “Arab framers”. A.I. spellers should not quit their day jobs.
