Considering you may make a few of these things for sale, I would recommend considering a split bearing design where the handles and rods pass thru the wall for quick bar changes; Just like fireball. Warrior has a unique quick change system as well. Obviously, choosing a different bearing type has a number of implications related to drill pattern, bar diameter, wall bumper spacing, men to men spacing, and rod length.
There is a number of reasons you would want this. Personally, I like that you can place the table in more places in your home if the bars come out, you can move the table more easily outside in the summer, tornado men sometimes break / changing them is annoying, bars can be swapped to simulate other tables.
In Vancouver, you can find used tornado coin tables... you just need to search craigslist more frequently. You may need to drive as far as Portland but tables list all the time. I've been watching two coins for a week at $600 and $800 USD. I would recommend spending your time restoring an arcade classic rather than reworking MDF to meet the tolerances required for an excellent table.
