Instant Pioneering 4 : A Signal Tower
To build this Instant Pioneering project you will need 14 long canes, 6 short canes, a good supply of elastic bands, a few metres of plastic string, one glass jam jar, a stump of candle and a length of soft wire ( to make a fireproof handle for your signal lamp).

Fig. 1: How to sheerlash two canes together to give you increased length. The overlap should be at least one quarter the length of one of the canes. Start by looping the band round one cane and work towards the end so that you can 'lock' your lashing by looping the band around it. If necessary, the point of a screwdriver can be inserted to leaver the canes apart to take the band.
