is preferred that the holes 17 be slightly larger in diameter than the diameter s of the arms extending through them so that there is a gap that can be filled by an adhesive usually an epoxy not shown an epoxy adhesive is also preferred for securing the brackets 16 to each other to produce the base 15 production of the un erected trellis assembly shown in fig8 requires no more than inserting appropriately sized ones 18 19 and 20 of the arms 12 in the respective ones of the openings 17 in the two brackets 16 applying an adhesive to at least one of the facing surfaces of the brackets 16 bringing the brackets 16 together and supporting the pieces in substantially the positions shown in fig8 while the adhesive sets when the brackets 16 are brought together this will urge adhesive out from between the facing surfaces of the brackets 16 and some of it will be urged into the interfacing portions of the arms 12 and walls which define the openings in the brackets 16 thereby securing the arms 12 to the bottom support 15 and vice versa after the adhesive sets the arms 12 will preferably extend in substantially parallel relationship with each other substantially as shown in fig8 this is a compact arrangement especially well suited for packaging and shipping the un erected trellis which would include at least one spacer and preferably at least the first and second spacers 13 and 14 the second step in producing the trellis 11 involves providing at least one and preferably at least two spacer brackets 13 and 14 there are openings in the brackets 13 and 14 for the arms 12 and the openings are graduated in the case where the arms have.
