For a second there I thought you meant the actual drive chain ! Off the ground is better than on the ground . As long as you can reach the anchor point , otherwise you ' re without a chain entirely . Get an Almax if you can , instead of Oxford . Or one of securityadvice . php <| sep |> I won ' t . I ' ve tested it and I don ' t like it . I will never change . <| sep |> Could try getting in contact with your local tech housemakerspace to get a cost on laser cutting , they may have a machine if you don ' t want to go out and buy your own . Would be a much faster and uniform process than by hand and should be cheaper than the labor cost of having your guys cut these with saws . E of course size comes into play , I may have inappropriately assumed you had small pieces for some reason . I would say if it ' s largest pieces laser cutter may be less efficient . Some variables there .
