The amazing Ruth from AisforAlice in true collective spirit has written us some instructions on building a test rig – I’m so excited for this, making it easier for Fancy dress costume makers! Thank you so much Ruth!
DIY Fabric Flammability Testing Rig
You will need:
4 x Aluminium strips/bars 100cm x 2cm (homebase)
5 x mini bulldog clips
- Put 2 x bars to one side.
Cut the remaining aluminium bars into the following lengths, using a hacksaw or tin snips:
2 x 62cm lengths
2 x 12 cm lengths
- Take the remaining 2 bars and cut a 12cm length from the end of each.
You should now have 2 x 62cm lengths, 4 x 12cm lengths, 2 x 88cm lengths.
- Lay out the 2 x 62cm lengths, apply epoxy glue to the top ends of each bar. Take 1 x 12cm length and apply glue to each end. Leave to dry according to the glue instructions, then lay the shorter bar on top of the top of the longer bars, creating an upside down U shape. Use 2 bulldog clips at the corners and leave to dry.
- Take the remaining 2 x longer lengths and place a mark at 62cm on each one.
- Bend the bars at the mark, to create a 45 degree angle. Be careful not to bend it back and forth as it will weaken the metal and it may snap.
- Apply glue to both ends of each bar, and to both ends of the smaller remaining pieces.
- Place a shorter piece of bar across the top of the two bent pieces, and again cross the bottom, to create a frame. Use bulldog clips to secure these joins until they are dry.
- Once all the joins are dry and solid, lay the U shaped panel on top of the bottom frame, and secure at the top with a bulldog clip.
- On the top panel, mark either side with permanent marker, to show 5cm from the bottom edge, and 7cm from the top. This is where the cotton thread will sit. Position your bulldog clips at these marker points, so the thread can be tied to it.
- Your frame is complete. If you feel the glue is not creating a sturdy frame, holes can be drilled at each corner and fastened with flat head screws for more stability.
Please note, you will need to position the frame on a table or raised surface to give the required clearance underneath for the flame positioning. When your test fabric is in the frame, the edge needs to be level with the bottom of the frame.
