Should garage door tracks (vertical and horizontal) be perfectly level with each other (as measured by a laser level), even if the garage floor is slightly unlevel? My garage floor is flat but not level (about 0.5" difference from level fromt left to right over 16 feet). Should I mount my...

I'm replacing my old garage door with a Haas 680 16x7 garage door, 1 3/8" thick. The bottom panel of the door doesn't has a seal so I have to pick one. One possible solution is to use a C-Channel seal, which I can use self-tappers to connect to the door. Another possibility is to use a 3"...

Existing garage slab is fine, has been sealed in the past with an unknown sealer. Home and slab is 50 years old. Some parts of the slab surface are starting to show water is not beading. Does anybody have a reference for how to proceed with a reseal? Is it ok to spot reseal? Is it ok to spray...

I’m talking about smooth/flat steel and cast iron wheels without any rubber / urethane treads. When it comes to cast iron and steel wheeled casters, Google is now returning nothing but sales and marketing material from caster manufacturers. It’s difficult for me to trust the marketing info...

I've only ever seen steel garage doors in the past, so this one's a bit of a mystery. To my surprise, my garage has, at some point in the 90's had some kind of hollow-core garage door panels installed. They are basically wood framed with a hex core of cardboard on the interior, along with wood...

Well, not my neighborhood library. The Smithsonian Institute NMAH Library, which happens to be in the next neighborhood over. I went to do some research on the National Museum of American History's collections. In addition to the Americana they usually keep on exhibit, they have an extensive...

Hi all, I figured you experts would know the answer to this one, pretty easily. Does anyone know what manufacturer/model makes box wrenches with the smallest outside radius on the "box"? I've attached a photo, since the terms are a little vague. Basically, the wrench pictured is 9/16". The...

Recently got a Rock Island 571. Lovely little 3 inch vise. It was cheap. For good reason, I suppose. The good: Main nut is good. Swivel base is good. Dynamic jaw is good. Lead screw is good. Handle is good. The bad: Swivel base lock lever is bent. The ugly: The neck is cracked. I'm not a...

Hi all, When restoring a Machinist Vise, what finish should be used on the slide? Assume that the slide has been cleaned to bare metal. 1. I assume no paint since the slide is machined to tolerances that paint would foul. 2. If not paint, then how to prevent rust?
