Greetings from a major lurker.
I have a project looming over my head - sealing 9 pretty tall roll-up doors on a commercial building in Tucson, Arizona. After some initial research I settled on brush seals as the best solution, found a good-looking supplier of those, and I am waiting for less than brutal weather to start installing them - we are having a scorcher of a summer this year (plus I am just dreading this and procrastinating).
The sides seem straightforward, I was thinking I’d use Tapcons or similar into the cinder block, predrilling with a hammer drill. I was planning on predrilling all the brush seals on the drill press ahead of time for ease and convenience when it’s time to affix them to the wall.
The challenge is the seal at the top of the door, where the gap is biggest and most in need of sealing. There’s a 1/4” steel header spanning the width of the door that I need to mount to or through, and its a good 12 feet off the level of the floor. The thought of drilling into that header 75 or so times, working overhead at the top of a ladder has me looking for the best way to do it. My current thought is to buy an inexpensive magnetic drill, possibly one of the Vevor models I find on their site, even if I need to support it somewhat working inverted. Thinking, mark and predrill the seal flange, Use magnets or even tape to hold the seal in position, and mark the holes to be drilled through the flange. Remove the flange, drill the holes through the steel for the fasteners. Phe the seals back into position and drive the tapcons through the pre drilled holes and the header and into the block above. So I have tons of questions:
Does this sound like a good approach? Totally open to other ideas, including that I am overthinking this.
Is a mag drill a good idea for drilling this many holes efficiently and accurately, overhead?
Will the magnet hold it in place while inverted, mostly?
Should I be thinking about just fastening TO the steel, instead of through it? If so, with what? Sheet metal screws?
This may be the only time I use the drill, so will I get away with an inexpensive Vevor? How bodacious of a model should I be targeting? They offer a boatload of models. This seems to fit the bill, but I am open to a better idea: https://www.vevor.com/magnetic-dril...ortable-mag-drill-press-810rpm-p_010469059052
TIA for your wisdom and experience.
