| Screwed up these two holes last week. This weekend, I rented a Makita hammerdrill, a 7/8" masonary bit, and a 1" masonary bit. Let's fix this screw-up! |
 |
| Drilling 1", oversized hole. |
 |
| Drilling complete. Depth of hole is over 6 inches (hit gravel underneath), which is what I should have done with all the holes in the first place. :) |
 |
| 1 week prior, filled both damaged holes, on either side of the new hole, with a premium Locktite epoxy. |
 |
| The Wej-It PD34 is a 1" diameter x 5" long drop-in anchor. This is one size over the standard Wej-It anchor supplied with the MaxJax. It accepts a 3/4"bolt. |
 |
| Luckily, my current home was built in the mid 1980s, and the concrete depth was over 6" deep! The end of the tape measure is grabbing onto the bottom of the concrete, as it meets the gravel. (They don't build houses like they used to...) |
 |
| The "sacrifical" -- threads are toast after setting the anchor -- bolt threaded into the anchor. |
 |
| "Slamming/Installing" (not setting) the Wej-It drop-in anchor. Left approximately 5/8" inches of thread at the top of the bolt to allow for setting the anchor. |
 |
| Tools for setting the anchor. Two complete rotations of the nut (bottom), while keeping the bolt steady with the rachet. Not pictured are very long cheater bars for leverage! |
 |
| My 7 year old daughter, putting on the initial torque. (Sweetie, don't round off the bolt head!) |
 |
| Torque complete (100 ft./lbs.) Bolt size 3/4". Grade 8. (Standard bolt size 5/8".) |
 |
| Decided to drill 5 more holes further away from the opposite lift column to accomodate wider vehicles (and will be nice to have those holes already prepared for anchors, should the concrete crack near the existing holes). |
 |
| This is the column fastened with the oversize Wej-It PD34 concrete anchor. |
 |
| This is the opposite column. |
 |
| Ran hydraulic hoses against the wall and ceiling. |
