Thread: clamping

G'day Tim,
Try some "band clamps" sold as frome clamps at many of the "bargain" shops (ie' supercheap etc) stell strap 4 corners and a tensioner absolutely brilliant. I use them on many of my projects including 6
60 degree corners, can't see why 45 couldn't be achieved as well.

Thanks for the reply E, l am talking about an open ended joint ie not completing 360 degrees,

Tim,

Cut some chocks with a 221/2 and 90 angles. Glue to outside of your pieces with epoxy, which should give you 2 parallel points. When all is dry, knock off the blocks with hammer & then scape off excess glue.

try a mitre clamp

While the use of Epoxy is rather extreme, I have had good success with glue pistols, the thermal glue. This comes of readily without staining. In the odd occasion that the glue does not want to let go, a heat gun will warm it enough to release. Position blocks both front and back and apply only moderate force. I have used other techniques, but this one has been the most reliable.

You can glue the chocks to pieces of ply that you can clamp to the workpieces. 320 abrasive glued to the ply stops it slipping on the job.
This is one of the reasons you can never have too many clamps!

I have seen a "jig" made whereby the pieces to be joined are aligned, on a flat board with guide peices (slightly oversize) matching the angle required. The joint is then held together using two wedges to provide a positive force to the joint.

Sorry but it is easier to draw then explain in writing.

I feel obliged to give the entertainment industry reply here.

Gaffa tape.

seriously plastic packing tape is better it stretches & creeps less.

cut your joint, make sure it fits.

then lay the parts to be jointed out on some packing tape being real carefull of the alignment then apply the glue & close the joint up. you can hold the joint closed by a variety of means including more tape.

If you do not mind small holes, use pinch dogs.I sometimes use them on the underside of joints.They are a piece of metal with two prongs on each end, usually come in sizes 1" wide, 1 1/2" and 3" wide. Tap in with a hammer, remove when glue dries.
