Over the years I have laid a bit of carpet here and there, and along the way acquired most all of the tools necessary to do that (knee kickers, knives, cutters, seaming iron, etc) but the one tool I did not own was a stretcher. Why? Because they are insanely expensive. SO.... whenever I needed one I rented it... usually not cheaply either I might add and inconvenient. Harbor freight sells a carpet stretcher ... $60 full price, and $40 when it is on sale. I have a coupon for 15% off and when it recently went on sale I bought one - $39.99 less 15% -= about $33. Overall it is not a bad little unit, but it only extends to about 6 feet.... I got to thinking and did some snooping around and found out that 1-1/4 inch electrical steel conduit is the exact size of one of the tubes (The big outer one) this thing uses - and that chain link fencing uses a small tube the exact size of the smaller one ( 1.314 inches in diameter and with one end smaller to connect together -both the conduit andthe fence tube are available at Home Depot)...so... about $20 later I have two 10' tubes, an inner and an outer... I cut them into two pieces each, drilled the outer and will be adding the steel clips to the inner (I was able to order them from HF) and I will have a stretcher capable of just about anything for less than the usual cost to rent a commercial one. I'll post some pics here later - paint is still drying.
