Lesson 8: Connections
Connections for hollow constructions can be simple or very
complex. Because of the steps of construction, you need to have a blueprint for
your connections as you start fabrication since many connections need to be set
up or fabricated in between hollow construction steps.
T-Bar or Ball/Socket
links:
Both the T-bar and and Ball/Socket links function the same
way. The crossbar of the T or ball sits inside the hollow construction. The
other side can either be a fixed link soldered onto the form or the same
(sitting inside for movement)
- Create your hollow forms but leave them open.
- Create the links- only put T or ball on one side.
- Drill hole in your form where the connection point is and slide link through hole.
- Solder that form closed. Hold the part of the link outside the form in a third hand to prevent from dropping into the form.
- When doing this you do not need an additional air hole.
- If fixed on other side:
- Close second form- placing the air hole where the connection point will be is will allow you to hide the hole under the link.
- Solder link to second form (over air hole if applicable)
- If moveable:
- Drill hole for connection in second form.
- Feed link through hole.
- Solder second T or ball onto the end of the link inside the form.
- Solder the form closed.
Jump Rings:
- Close your forms.
- Solder half jump rings to the form where you want your connections.
- Finish the forms to final finish (minus patina).
- Link the forms together and solder the final ring.
Tube Hinges:
Tube hinges work best for longer hinges.
- Close forms.
- Solder knuckles on to forms.
- Solder knuckles to one side, then measure and mark the other side. Cut the tubing a little longer than you need so you can file down for a perfect fit.
- Ball one end of the hinge pin and feed through.
- Set the other end.
- For tricky and inset hinges, chasing tools work well to reach into tight areas.
Sheet/Rod hinges:
These types of hinges can work very well for hollow forms
and for small hinges.
- Take a sheet and fold into a U.
- Alternately cut out a slot in a thicker rod to form a U shape.
- Fit single sheet or rod into the opening to complete the hinge.
- Drill hole through.
- Solder U to first form.
- Solder single sheet or rod to other form.
- Ball up one side of hinge pin and feed through.
- Set other side.
Rivets:
You can rivet forms together as well. This is tricky, and
mostly used for when you want 2 forms pivoting around each other.
- Create forms but leave open. One form should have the side to be riveted already attached, then other one should not.
- Drill hole for your rivet.
- Ball one end of the wire, feed through the separate sheet and cut to length.
- Place on block and set.
- Solder both forms closed.
Other connections:
- Drill holes and feed a jump ring through the holes.
- Drill holes and thread together. Feed small lengths of tube between forms to separate.
