I have one carpet to lay and I'm not too keen on spending £30 on a knee kicker tool.Does anyone know how much protrusion I should give the gripping teeth (screw tips) and if they need a forward facing angle or not?Also, how many teeth and over what area and what the spacing of the teeth should be.I have plenty of wood and screws in the garage and feel that I can save myself some money by making my own.I've found this pic of one but I can't see the underside of the gripping face.http://www.screwfix.com/sfd/i/cat/24/p1127924_l.jpgTIA Ady...
If you are thinking of making a gripper out of nails and screws with an old piece of wood then forget it, it will look bad and perform even worse. Professional knee kickers have variable nail extensions to suit the carpet concerned.All you are likely to do with a home-made version is tear the carpet.Invest in having it laid properly otherwise it will look awful.As a seasoned DIY'er, there are only 2 things that I would not attempt to do myself:Plastering and .... well you've guessed it.Cheltonian
I have one carpet to lay and I'm not too keen on spending £30 on a knee kicker tool.You could hire one http://www.hss.com/g/58399/Carpet-Stretcher.html
Hire one. Or buy a 2nd-hand one on ebay then resell it afterwards.If you're still intent on making your own, here's a picture of both sides:http://www.carpettool.net/Carpet_kicker1_web.jpg
