Pre-Drill and Anchor Base Plate

alright step of this next operation we're gonna be start anchoring the bottom part of the board we're going to be using actually a weatherproof board and we're a start anchoring right into the concrete so for that application we're going to use these anchoring bolts that I found at my local hardware store these ones are two three-quarter inches long which is gonna be plenty to go through the board into my concrete far enough not to split this floor inch thick concrete so we're going to use that they're recommending to use a pre drilling pilot hole for your concrete they say drill it about a quarter inch past the overall length of the bolt you're going to be using so I got my little marker on top this is a carbide tip so I should go a lot smoother and then the last drill that I'm taking is just a drill bit to pre-drill the wood afterwards I'm going to switch to drat that drill bit and then we're gonna start lagging this into the concrete so we're gonna place one every about two feet so let's rock and roll all right so I guess today's gonna be a day of screwing up so I everything was fine the only I screwed up was is the drill bit for the wood or for the concrete is a little bit shorter the measurement is correct my flag is correct it's just it's not long enough to go through the wood and then through the concrete so what I'm going to do is I'm going to pre-drill it create a little marker move the wood and then drill it all the way through hopefully I don't screw up the entire line so that all the holes from the wood into the concrete line up once we're done so let's get it done the harder way I guess okay so drilling through concrete it's a lot more difficult than I thought it would be a little bit of advice if you're gonna do it I know some drills have a hammer setting go get a nice hammer drill that you can just go right through it with even speed and pressure I probably destroyed my bit and I probably made a lot more difficult than it should be so take it from me go get the right tool for me but nonetheless we've drilled our holes in the concrete they're perfect we're gonna take our pressure treated two by fours put it on top and then we got those blue lag bolts we're gonna put on top specifically for concrete and then we're gonna put a fat washer on there so it gives a little more strength I got them spread out about every two feet so let's get cracking away oh boy oh boy oh boy it's all lined up it is so strong look I'll tell you what drilling is a…
