Hi here is a very easy and quick forge table, made from an old builders trestle,
step 1 slide out the top bar and put this to the side, this will be the table top.
step 2 , cut the upright at the hight you want, i went for 32"
now we have the upright and a H piece,
Step 3, cut the bar joining the uprights and disregard (this is the only waste also this is often 1" square tube and might fit your hardie)
, this will leave you with 2 uprights and a H
Step 4, take the piece we slid out on step 1. and cut to required depth of table. i went for about 28"
step 5, take the H piece and cut of the longer side of the H, (Keep these safe as they are very important for the final step.) then insert the " not a H any more" piece over and square it up of the front bar. you can weld it or tech screw it.
