Welding related - mounting compact bender outside

admin

I just purchased a compact bender and decided to mount it outside, instead of drilling holes in the garage floor. My thought is to pour a small concrete slab 12"x12" and 18" deep next to the driveway. I would just mount it when using and take back into the garage when finished. I don't think my homeowners association will be agreeable to leaving it up when not in use. Obviously this will be exposed to the elements and the mounting bolts subject to rust. Would it be better to install bolts sticking up and make some type of long nut to coverthe bolts and protect the exposed portion from the weather or is there some type of inground recepticle for bolts that can be plugged when not in use to protect from rust? Are there stainless steel anchors available and would they be compatable with concrete?The bolts will probably be  5/8" since that is the size of the hole in the base of the bender. Thanks
Reply:Instead of bolts that have threads the get messed up over time. How about a quick pin set up.Studs protruding from the slab and a horizontal keeper pin?
Reply:I would stick them up... weld them to other steel stuff to extend their holding grip down into the concrete.... make a yard appropriate item.... perhaps a flower pot holder which fits the same bolt pattern.... and is there when the bender is not in use... and keep antiseize compound on the threads all the time...Weldandpower Lincoln 225 AC,DC with Briggs 16hp gas engine.WW2 era Miller TIG.
Reply:They make female inserts for concrete. It's sort of like a nut that is set into the concrete that you can run a bolt down into. Not sure if they have them available in stainless or not, but it would not surprise me for marine dock applications. I use the same idea in my shop floor. To keep crud from filling up the female threads, I run a large allen head set screw in to "fill" the holes when not in use. For outside a short bolt would work fins. Add a tight fitting rubber washer or O ring to help keep out water and snug it down well..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:If your vehicle is available then you could create a trailer hitch mount.
Reply:I'd go with a 1/2" bolt and use a big washer, as drilling holes in concrete is more art than science. These anchors should do the trick.http://www.mcmaster.com/#97082a033/=d8hd3bLast edited by fortyonethirty; 07-18-2011 at 07:16 PM.Ian TannerKawasaki KX450 and many other fine tools
