Home Depot doesn't cut MDF anymore? | Home Theater Forum
2004年2月4日 — 2. MDF is abrasive and very wearing on saw blades. 2. MDF is a low-value sale - a few minutes labor to slice up a $15 sheet is not a profitable situation. Here's what I did last time: I rented a Lowe's pickup for $20, loaded 5 sheets of 3/4" MDF, drove it home, unloaded it, drove the truck back, all in an hour.
MDF or Particle Board for a Stage? - Home Theater Forum
2003年9月24日 — MDF is just finer particles than particle board. Either should be fine. You should probably go with 1" thick (or glue up two 1/2" pieces) for strength unless it's not going to get traffic. OSB (Oriented Strand Board) could also be a good choice to save money. It's commonly used as a roof underlayment or wall sheathing.
The Smell of MDF? - Home Theater Forum
2004年2月16日 — Messages. 91. I agree with Dave's suggestion. In addition to the smell, MDF will also absorb any moisture from the air over time so I applied two coats of primer/sealer the interiors of my ported Tempest and my LCC to deal with the odor and to minimize any moisture absorption Once the primer was completely dried there was no more smell.
Where to find 1.5" thick MDF? - Home Theater Forum
1999年6月11日 — Well braced 3/4" void free, or thicker, plywood such as Baltic Birch/Appleply/marine grade are the best cost-to-weight-to ease of construction performers IMO. There's more than one way to meet the goals though. 10ga cold rolled steel, or 1.25" thick MDF are ~functional equivalents.
How would I completely roundover an edge of 3/4" MDF?
2001年6月4日 — Eric Kahn. there are 3/4 roundover router bits availible, you just need to find the store that has one, you would want one with a pilot bearing and then screw the piece you want to round over to another piece that has been cut out as a guide plate for the pilot bearing. or use a circle attachment on the router.

Is 3/4" MDF strong enoguh to hold a 27" TV? - Home Theater Forum
2002年7月19日 — One half longer and narrower (2' x 6'), the other half shorter and wider (4'x3'). Those dimensions are rough guesses, I can't measure it right now. On the underside of the out side edge, all the way around (about 4" deep) we doubled the MDF up to 1.5" thick. Then 4 or 5 places around the desk we made it 1.5" thick across the desk.
Is there a "Best" wood for speaker stands? | Home Theater Forum
2002年1月28日 — A high MOE would be >1.0 million psi. For example, 3/4" MDF averages ~527k, and 3/4" marine grade ply, ~1.8m. Since rigidity increases with the cube of thickness, MDF must be ~1.125" thick to match the plywood's stiffness, though due to its higher density has a better damping factor (Q).
Biscuits in MDF? - Home Theater Forum
2004年4月22日 — Mar 3, 2003. Messages. 407. Biscuits are ideal for MDF, IMHO. I use biscuits in all my MDF projects. Typically, I use size "0" or "10", depending on the thickness of the MDF and the stress on the joint. The fact that there is no grain structure is actually why biscuits are preferred--- fasteners, like screws, won't hold nearly as well.
Pneumatic stapler for MDF? - Home Theater Forum
2003年10月12日 — 9. I see everyone just glues their MDF for speaker projects. I have a pneumatic narrow crown stapler that really holds wood together almost as good as screws. The staples are about 5/32" wide and I have 1 1/2" long staples. The surface wound is very minimul and depending on air pressure, usually goes below the surface, leaving a tiny spot to fill.
Solid wood vs MDF - Home Theater Forum
2003年2月24日 — The Young's modulus of elasticity (MOE) of red oak is about 1.55. The MOE of MDF (medium density fiberboard) is about .55. This means that red oak is approximately 3 times stronger than MDF. When oak is glued to MDF it makes a very desirable baffle. The baffle becomes incredibly strong (oak) and dead (MDF).
