I have been thinking about potentially lighter/cheaper options to scaffold tubing for our IPSC'S and any other steels we might use. I looked at this website www.lastands.com who sell a polymer connecter to use with rebar to form an A-frame stand. Reviewing their video I think the stand might be successful because it 'gives' on impact and the flexion absorbs the bullet strike without being knocked over.....in the video at least!
Anyway....would it support the weight of an IPSC?
Manufacturer says it can support at least 70lbs.
Polymer brackets are $40 a pair (rebar sourced locally) .
The polymer brackets are claimed to be self-healing on bullet strike.
Snag is that postage for a single pair is over $30!
4 sets postage is $67.
I am going to make some equivalent brackets in oak to check if the rebar crossbar will actually support an IPSC.
A direct hit on a wood bracket will obviously kill it but they will be reasonably cheap to make.....they may not allow the same degree of flex as the polymer brackets and so targets may be more liable to topple but at least we can test rebar support weight capacity.
Dependant upon results there are options to group-buy Last stands product and share postage, make more oak brackets or revert to heavy/cumbersome scaffold tube.
