Here is my 2'x2' portable bench (used for pistol calibers) built from rough scrap 2x4s with scrap OSB top covered in reinforced vinyl with satin finish to hide the ugly rough OSB and as cheap temporary covering. But after almost 10 years, the top has no rip and still looks great. At the time, I had 2'x6' and 2'x8' benches in the garage (castered with HEAVY casters but I got tired of reloading in the 100F+ heat of garage and these industrial benches built to take the weight of engine blocks were given to friends who needed heavy benches). The 2'x2' bench was meant to be temporary until I got the portable 2'x3' bench finished but since it worked so well, I ended up keeping it.
