My kids will never forget to clamp a piece they are drilling..... They watched me stupidly try to hand hold a replacement inertial reel belt I got for my tractor (factory part). The new part had a smaller hole than the old one for the belt, so I tried to hand hold it and drill it out with a...

I have a mid 1990s VR90B. I would have no problem sticking the forks in the ground and pushing back out. If the boom can lift 9,000 lb in my case when fully raised, it can push back 9,000 lb. I just wouldn't want a sideload on the boom. I also have used the boom to raise the front end so...

You couldn't use the boom to push yourself back out?

Somewhat off topic, but there are laser paint strippers now that are color tunable so you can remove the topcoat and leave the primer, or striping/lettering without messing up the base coat. They are $500K machines, but if you can find someone that has one it might be a way to go depending...

The salt is way flatter than the interstate. That’s why people go there for land speed records. Suspension is beneficial at higher speeds. For example, if you have an inch high sine wave with a 176 ft length, that is moving you up and down an inch every second at 120 mph. Many racing type...

Adding an outlet would be my first choice. I would next suggest checking to see if the motor is 110 v capable. It may just require moving some wires or jumpers. You would also have to check if the control electronics need to be modified. Alternatively, assuming your lift is in the 3-5 hp...

Like everything else, it depends, IMO. If you are working in a small bay, a cart may not be useful (not saying it won't, I just don't have experience). Working on small aircraft, it is almost indispensable. You may be working 50' to 100' away from your large box, or even roll it across the...

I haven't been involved in running there since the mid '90s, but FWIW..... The salt is globally very flat. Every year it floods, and as the water evaporates you wind up with a surface as globally flat as gravity can make it. They will typically then drag the course with weighted beams to...

Front end loaders with forks should work.

How did you match the pump to the engine and the surface cleaner to the pump?

Nice build. I will note, however, that while the design you have drawn LOOKS nice, a plainer design will be faster. (e.g. Summers Brothers' Goldenrod)

To be clear, the condensation isn't an issue as it is on the outside of the buildings. It is just that if you can see the lines of the purlins and girts in the outer sheathing that there is a different heat conduction with respect to the inside, indicating that, indeed, you lost R-value in that...

It used to be normal everywhere, but the more modern building codes (e.g. IECC 2009) in colder climates now require blocks between the purlins and insulation to keep the R-value up. On many steel buildings you can see lines of condensation where the purlins or girts are. Here's an...

I don't have an opinion on JLG or Genie, but whatever you get, check the battery condition, as it can be $2K or more for a set of batteries.

For my aircraft hangars the footings were required to be completely independent of the slabs, and are insulated from them with about 1/2" of foam. I'm not sure whether it would have been required in a monolithic pour. With respect to the slope......many jurisdictions require a slope to the...
