Now I have done some research I thought it might be useful to someone else out there who isn't lucky enough to have a joiner for a husband like Starryeyes (believe me when you see mine banging in screws with a hammer I don't let him near any DIY) This is the web site I used
http://www.freewebs.com/makeyourownagilityequipment/jumps.htm. After looking at the David Dowker jumps I thought that the crosspiece was holding the side pieces together and would not fall if the dog hit it. I have e-mailed to ask if this is the case. This pattern that I have used has a fixed cross piece low down. I have not used clips like him - the jump can only be used from one direction. I have used 2 pipe clips screwed together and filed away the inner one to form a cup. Now can be used safely from both directions.
I used 8 x 3m pieces of pipe and made 2 jumps and a 3rd short of a 10 inch piece. I think with 2 more 3m pieces I can make a fourth jump. So: 10 x 3m piping = £14.80 + 16 90 degree tees = £23.60, 4 packets of pipe clips = £5.52 + packet of machine screws (have nuts) = £1.30 total for 4 jumps = £45.22.
The down side is that it took me about 3 hours to make this morning, an hour yesterday shopping and extra time to get more bits. The upside is that the clips slide neatly up and down the poles and I had my dog jumping at competition height in minutes!!!!!! Do hope this is useful to someone. :rolleyes:
