comment How can I compute the force with a fulcrum on a Murphy bed?
That amount of force has to be perpendicular to the wall, not straight down. Since you can't brace very easily against the bed itself (which you're trying to move), you'll have trouble even if you've got 3X that amount of force working for you in the form of your weight. Plus, the upper bunk needs the force applied at a height of 6', which makes it awkward for even a tall person, and downright impossible for someone short.

comment How can I compute the force with a fulcrum on a Murphy bed?
I'm confused by your description. Is it stuck in the up position? In order for me to answer your question, you'll need to provide the total weight of each bunk, with mattress included and the weight of each support leg for the top bunk. Also provide the height the gas pistons are attached to the frame above the bed. This geometry is needed since it affects how much of the force is directed vertically and horizontally.

Is there a reason you can't cut it as close as possible and hide any errors with trim?

comment How many arms should a 5.8m long awning have?
There are a lot of variables here that are going to be hard to account for over the internet. Could you post a picture with a rough sketch overlayed? Will snow loading be an issue? What are the awning frames made of? Etc. It's very likely that both contractors are "right" if it's right on the verge of needing 3.

comment how to design and buy materials for breakfast bar/standing desk?
I've also never heard of a Home Depot that won't make a few cuts in-store, although they may charge for it. A quick survey of a few Home Depots on Yelp in/around NYC shows that they do.

Awesome, I actually have a block of this lying around in the garage. Don't know why I didn't think of it.

comment Can I operate a 120v 60 hz sewing machine with a 220v 50hz power supply?
It also depends on the complexity of the sewing machine. Is it a fancy new computerized one? Then probably not. If it's an older model that doesn't have any fancy electronics, then there's a possibility it will work.

Repair or replace? Maybe you could post some pictures of the nature of the damage.

comment how to fix blade wobble in circular saw
That few millimeters will magnify due to the cantilevered nature of the saw blade spindle. There shouldn't be any clearance at all between the inner diameter and the shaft.

comment Projector ceiling mounting using 2 screws instead of 4: risky?
Do you have attic access? I'd get up in the attic and sister a 2x4 flush with the bottom of the ceiling joist. Do both sides if you need 4.5" wide rather than 3" wide. Then no more worries, you can mount it using all 4 screws.

comment Is it safe to remove risers from stairs?
Agree with BMitch. My answer to this question points out that some residential codes specify as little as 3/8" as the maximum rise variation.

This is my usual method. I've heard them referred to commonly as "end nippers."
