I Have a Solid Wood Body Electric Guitar with a Cutaway and Richenbacker Horseshoe Pickup.?

If your avatar picture is of said guitar, God only knows, theres a few one piece guitars out there but not very common. and most are custom made, the only real manufacture I can think of is Rushmore,

1. Why would a solid wood bed frame have a CA proposition cancer warning?

Probably the finish. The good news is that the cured finish is probably fine. If you are concerned, call the manufacturer

2. 30 gallon fish tank on a solid wood desk, will the desk collapse?

i got a 40 gallon tank on an older weeker desk it is a wood desk but its old and it isnt going anyhwere

3. I-ball advertises that their speaker is made from wood, so gives good sound quality?

Well to expand on what agp90spr... said; Yes, sort of.. That is as opposed to the plastic that most of the other teeny weeny speakers are made of. MDF (Medium Density Fiberboard) is wood, in the loosest use of the word - ground up wood, cellulose anyway. The ideal material to use for speaker enclosures is a substance that is as dense and non-resonant as possible. In an ideal world speaker enclosures would be made out of sheet lead, depleted uranium, reinforced concrete, adobe etc,. but of course that's impractical. That's where MDF comes in. It's heavy and fairly non-resonant, particularly when braced. Solid wood is undesirable because it has resonance. I doubt that iball speakers are made of solid wood. It's almost certainly MDF with a layer of wood veneer over it. What they may be bragging about is that they use the aforementioned "wood" MDF and real wood veneer as opposed to MDF with a layer of wood grain vinyl. Quite frankly when speakers get really small it's almost a moot point what the enclosures are made of. The panels just are not big enough to develop undesirable resonance frequencies. Even if it is plastic, as long as it has adequate bracing ridges molded into the enclosure, I doubt that there is a noticeable difference. Probably just another exaggerated advertising claim. Nothing new in the world of speaker manufacturers

4. For the vertical stud (2x4), builder A use solid wood stud and builder B use Finger Joints stud.?

finger joint studs are stronger and straiter. but i would not let this determin who i hire. ask for reference and go and look at some of there work. a little time spent now will save lots of headache (and money later)

5. How do I paint my solid wood bedroom suit black?

Well to start if it has a finish you will want to sand it down before you whip out your paint brush. This can be very tedious and tiring. You might want to consider getting an electric sander or the attachments for your drill if you have one. It will make the task easier and faster. Then you can do a black solid paint or you could consider doing a black stain. The said will keep that wood looking appeal but give you the color you are looking for. It's up to you. Hope this helps and good luck!

6. Is it recommended to make a 4.6 ft longboard with solid wood, laminates or single panels?

Length is not a critical as width for a glue up, unless it's structural. Plywood maintains a much flatter surface, is stronger, and resistant to load than solid wood. A 4.6 foot long board should be from a solid piece. If the width exceeds 8 inches I would do a glue up if I chose solid wood as the solution. As with all material choices, application is critical. You have not shared the application so its the best answer I am able to offer.

7. Does solid wood floor deform over time?

Yes very true this is because solid wood contracts and exands much more. The solid wood also has more cracks for water or that spilt cup of tea to get into it and damage it making it deteriate faster over time more than the engineered or top layer wood. But you have to ask yourself how much quality you want.

8. What is the difference between timber and solid wood in architecture?

Timber - in architecture - is generally large pieces of wood (usually used for structural purposes). Typically solid wood, and typically larger than 4-6 in the smallest dimension (thresholds vary), and often milled and dried specifically for use as architectural timber. This can be used for columns(posts), beams or as parts of trusses or other structural systems. It will occasionally be used as a design element - e.g. as a bench where it's not building structure.This is larger than "dimensional lumber" or just "lumber" or "wood" which is typically things such as "2x" lumber. "4x" lumber is often referred to as timber, but "timber framing" often is considered to be 6 or larger.Heavy timber is BIG chunks of trees - think 12-16 pieces in the smallest direction."Engineered timber" generally refers to "timbers" which are made up of a number of smaller pieces of lumber. carefully (factory) glueing together structural grade 2x10's will get you one significantly bigger "piece of wood" which would take generations to grow, or in a shape that nature won't produce, and allow you to control and compensate for grain direction."Solid wood" is a marketing term relating to something built out of pieces of wood rather than other elements, or small bits of wood. e.g. a bookcase made out of "solid wood" should have no plywood or particle board in it, but may have a veneer for certain surfaces to hide end grain, or hide lower quality grain or less desirable species of wood used as structure. In flooring it'll mean the entire depth of the tongue and groove flooring is one chunk of tree, as opposed to having the top wear surface being wood, and the depth of the piece being hardboard or another wood product
