SoCal Dave Posted June 25, 2014 Share Posted June 25, 2014 I want to convert my old anvil hardies, 1" hardy hole posts, to my larger anvil hardy hole, 1 1/4". I was going to slip a 1 1/4" OD square steel tubing sleeve over the one inch hardy post. Unfortunately, they aren't thick enough to give a snug fit. They come in 11 gauage and that is a hair to thin. But, the 1 1/4 aluminum sq tubing is .125 thickness and would be perfect. So, would it cause problems with the alum up against the steel? Is there another way to give a snug fit to the larger hardy hole. Quote Link to comment Share on other sites More sharing options...
arftist Posted June 26, 2014 Share Posted June 26, 2014 Get some 1/8 " steel strip. Bend it around the posts. As to your other question, if the metal is kept dry there shouldn't be any problems, BUT aluminum can bond to steel in so strong a manner as to actually cause the destruction of the steel during the process of separation. So, if your anvil is outside, don't leave a hardy in for long periods of time. Quote Link to comment Share on other sites More sharing options...
L Smith Posted June 26, 2014 Share Posted June 26, 2014 Zink chromate primer is what is used in aircraft for this problem. However if the AL sticks in the square hole but not to the hardy there shouldn't be a problem. May need to file the inside of the AL some to make a better slip fit.

Jim Coke Posted June 26, 2014 Share Posted June 26, 2014 Greetings Dave, Try to fit an 11g angle shim into the ID of your tube.. This will shim 2 sides and your 1in hardie will fit snug... Just tack weld the top and bottom seam... Works well... It does not matter if the hardie is not perfect in the center... Forge on and make beautiful things Jim Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted June 26, 2014 Share Posted June 26, 2014 Good Morning Dave, I agree with Jim, make an "Angle Iron" shim. Look on the floor for scrap and use what is handy. If your piece of Aluminum is handy, use it. It is a shim for a Hardy!!!! There is no current going through it, there won't be any electrolysis (unless you unleash some from your vocabulary and make sparks fly :) :) ).

ironwolfforgeca Posted June 26, 2014 Share Posted June 26, 2014 Dave what I did with my 300 wt PW 1-1/4 hardie was to weld a piece of sq tubing in it so all 1" hardie tools will work on all 3 anvils I have on one anvil I went from 15/16 hardie to 1" with a die grinder & file was worth the time all my tools are set to 1" Quote Link to comment Share on other sites More sharing options...
