Lift install screws up a hole

[acidice333]

Drilled some holes and I screwed up one hole. Its offset so only 3/4 of the anchor is showing.

What do I use to elongate the hole in the steel plate?

Die grinder with a burr head would be my choice.

Torch if you are good with it, or a large rat tail file. As noted above, the die grinder with a rotary file or burr would also work well.

A plasma cutter would make quick work of it.

Die grinder would be the choice tool for me too. I drilled the holes for my anchors with the lift setting in position. Was this an option?

 

[acidice333]

Thanks for the tips. I'll try the die grinder with bur.

Sadly it wasnt an option. the holes in the plates are 7/8 give or take and the anchors are 1". I do have a 7/8 bit masonary bit but it would most likely catch on the plate

I did drill pilot holes with a 3/8 bit I think it was.. some of the anchor bolts are a bit tight so I will need to make the holes a bit bigger. but yeah its just one that is only showing 3/4 of the anchor thank gawd its on the inside so not that big of a tension on it.

Okay?? What am I missing? A 1" anchor and a 7/8" hole.

What are you missing?

Just 1/8".

yeah really, why are you using 1" anchors with a 7/8" hole.
usually those lifts if they have a 7/8" hole they'll have a 3/4" anchor so you drill right thru the base plate.........eliminates all those mis alignment problems.

1" anchor with 3/4 thread, and a quick measure with my caliper gives me 7/8" hole on the plate.

Are you installing a Maxjax by any chance?

 

[acidice333]

Nope. Its the NAT C7000. Anchors require a 1" hole, the plate holes are roughly 7/8" so I cant quite use the plate as a template to get perfect 1" holes.

Odd, I just used 3/4" Hilti bolts.

You must be using drop in anchors. I had wedge anchor in my head so the numbers didn't make sense.

The Maxjax I installed needed 7/8 holes in the concrete and the lift had 7/8 holes on the base. I just used holes one the base of the lift as a guide with a 7/8 bit.

Maybe use 7/8 hole as a pilot hole through the base and then redrill with 1 inch?

edit: I re read your post again and your holes are only roughly 7/8 and they catch the bit so not feasible.
