Even with all of those faults my only regret is that it is too ugly. I didn’t take the time to make it more visually attractive as I was eager to get right into making beautiful furniture instead. Twenty years later the furniture is still beautiful (or not) but I go out to the shop and look at a drab uninspiring workplace. Yeah, nothing wrong with having a visually inspiring workplace in my opinion. All that shop furniture I slapped together years ago with no concern about aesthetics is getting replaced bit by bit. Why should my shop be downright ugly when it is one of my favorite places in the world to spend my time? I see no reason for that, but that’s just my opinion and as we all know everyone has their own one of those… Sadly, no one pays nor reveres me when I offer mine. bummer, I could be a rich egotistical maniac if they did coz I sure offer it enough. 😉
Put the upper panel of MDF on your glue-up surface, bottom side up. Put the bottom panel of MDF on your other surface, bottom side down. (The panel with the holes drilled in it is the bottom panel, and the side that has the your layout diagram on it is the bottom side.) Chuck up in your drill the appropriate driver bit for the screws your using. Make sure you have a freshly-charged battery, and crank the speed down and the torque way down. You don't want to over-tighten the screws, MDF strips easily.
There are a number of tricks to using a router. First, the bit spins in a clockwise direction, as you look down at the router from the top. This means that when you cut with the router from left to right, the bit will tend to pull the router away from you, and when you route from right to left, the router will pull towards you. So, if you're hooking the edge guide along the near side of the board, route from left to right, and when you're hooking it along the far side of the board, route from right to left. Second, always test the position of your bit on scrap material. Your odds of getting it exactly right by eye are nil. Third, don't cut more than 1/4" deep on a single pass. We want a 3/8" deep grove, so make your first pass at 3/16", or thereabouts, and make a second pass to reach the full depth.
Beyond the weight capacity, the Grizzly is also the largest table top on our list and in more ways than one. For a workspace, the Grizzly provides 5’ of length by 2 ½’ of width. There is not another table that really comes close to that size. Another size advantage of the Grizzly bench is the table top’s thickness. While the standard thickness of the table top for a quality woodworking bench is 1” with lesser models often offering only ¾” of thickness, the Grizzly provides a 1 ½” thick table top.
