Ouch… I’d be inclined to weld it up, drill, and retap at this point. That would have been a bolt that threaded into the threads in the hole - therefore not needing a nut.

If you want a real wake-up call about the dangers of gloves, loose clothing, or loose hair, just plug “lathe accident” into Google images… :shocking:

All depends on how soil conditions and how you are designing the foundations.

Pretty much this. If you’re looking at fullsize cars, trucks, SUVs, or such I’d say 24’ deep is about a minimum. Twelve foot wide is about the bare minimum for a bay - eight foot for the bay with two feet on either side. So 14’ would allow some storage down one side or some work room. But that...

This. Here is a picture of my cousin’s son’s hand - a year after “the incident.” He had gloves on because he was loading/unloading pieces into the drill press. He wiped across the table to clear the swarf and the bit grabbed his glove - smashed bones, pulled tendons, and broken wrist. He had a...

I have a couple local structural engineers I work with. Typically you want to find the “Joe Smith, PE” type place instead of the “ACME Megacorp Engineering, LTD” type place. Depending on area, probably in the range of $125 to $250 an hour and four to eight hours. Structural modifications are...

I put lights on my 70-year-old father’s mower so he could mow in the evening when it was cooler rather than be out in the blazing sun. After 10pm is later than I’d expect my father to be out there, but it also sounds like it is quite a bit hotter out there.

Typically you figure this out before you start and put equal amounts to either side. Depending on how the spacing works out, you either figure with a sheet in the middle or a joint in the middle and space things out from there.

As STS proves, HF’s whole operation is based on the sales and coupons. I’ll guarantee that they’ll sell more of these with the $169 coupon than they did for the months that the regular price was $169.

Re: Rebar can cause shrinkage cracking There’s your problem… I wouldn’t go any more than 12” o.c. for such a slab. Also looks like it cured too quickly and wasn’t kept damp long enough.

If you want a car lift - or think you might want a car lift in the future - go 12’. Otherwise, go 12’ because you’ll probably end up wanting a car lift in the future… ;)

I have a copy of a book called “Ramah Machines Metal Disintegrator by Ben Fleming” that gives a pretty complete set of instructions on building an EDM. I started amassing the materials for it, but got busy with other things and never got back to it. I see copies of the book on eBay, but it...

Even if it isn’t stolen credit cards, there are a lot of scams going on. Read through this: https://www.entrepreneur.com/article/278622 TLDR: People find items to sell, get an order, and then place an order to the original seller to have it shipped to their customer. Downside is that the...

^^ This. Calculating out a beam is a lot different from calculating out things for a gantry crane. I’m thinking there is a reason why your last setup collapsed… No idea where you are, but building codes likely have something to say about it as well.

From recent emails and flyers, it doesn’t look like it has affected the way HF is advertising...

Hard to say from just the photos, but I do see some signs that align with what the mason is saying of rebuild over just repoint. The problem is that water gets in from the top and works it’s way down. At that point it isn’t just repointing but putting it back together structurally. I would not...

I’d really be contacting a structural engineer about something like that than asking for input from the internet...

I took some photos when I was in their studio the other year. It is somewhat typical for “theatrical set” construction - much rougher up close than what you’d expect. The first photo is of the brick wall. It is just printed panels - you can see where they pieced the panels together to the right...

But that one leg of the tripod is using the rest of the truck’s weight to hold it in place. ;)

You and I have much different views on “big/heavy items” - my big/heavy items need a forklift to move around… ;)
