Dang it, sorry!

Sorry for how off-topic this is (I also haven't posted in a while!)
------

My post is very long. I have a TL;DR about 2/3 of the way down, and I hope there's enough information there.

I...

Not yet, I just put on my 4th coat of paint. It's too thin to sand, I think I need 2 or 3 more.
Then, I have sandpaper all the way down to 2k.

That's too diffuse. I want something like this:

Thanks!

Varnish, lacquer - whatever... What product should I use, that isn't super expensive, to get a mirror finish on my latex-painted box?

Also, I read on a forum that Polyurethane isn't great for a...

Is it difficult to make a sled for a planer like this one?

Thanks.

Why do I hear people getting both a planer and a jointer?

Can't you use a jointer as a planer? As far as I understand, a jointer is the same thing as a planer, except that it also has a flat...

I didn't.
Thanks.

No, only brush cleaner..?

Wheel,

It was around 80º in the room.

What do you mean by this?
"The possibility of the solvent you were using to wipe over between coats could also be the problem."

Is it because a lot of my polyurethane turned hard in the can? I assumed because it seemed to turn back to liquid that there wouldn't be a problem, but did it create these specks?

It's MDF, mate. No displaying bare wood.

I sanded black paint to 220.
Put on a coat of poly (this time it was semi, last time it was full gloss.), and sanded it at 800.
Cleaned with mineral...

It is brushed on.

I cleaned the table with mineral spirits and a rag before I put that layer on.

I use the high gloss polyurethane, and this is what happens when it's all dried.
What's going on? I've re-tried it 2 or 3 times, and this keeps happening.

Alright, thanks friend.

If I use a router to follow the line I cut, do I have to 'free-hand' it?

Thanks.

If you look at the link below, you will see that the frame (where the screws go) is not a circle, or even a square. It's an inconsistent shape.

How do I flush mount this?

Thanks.

Speaker...

I found one on Harbor Freight, and some of the customers even mention using it for latex.

Thanks, mate.

Black interior latex, I think it's 'gloss.'

I have a nice compressor, 13.4CFM @ 40PSI.

What type of spray gun should I use, for painting wood? Is an iwata knock off, which is normally meant for cars, just fine for interior paint too?

Denatured alcohol, or Rubbing alcohol - VK4?
Thanks.

Thanks again.

Thanks.

To make sure we're on the same page,
I'm talking about the "streaks," the ones that look like I took a rubber eraser to the wood.
Not the swirls where it looks like single grains gouged...

It's raw MDF.

Vk4,

Thanks for the info, mate.
Are you saying not to sand the primer/undercoat? Also, what should I use for an undercoat?

When you say the 'lightly rub back' the black paint, you mean to...

I was looking at sandpaper with grits above 4,000, and found micro mesh with up to 12,000 grit. They even have it in 5" velcro discs.


However, then I found this:...

Here's a picture,

Bump.

Ouch...
I hope that takes a while, I started doing wood work mostly in the last year.

I'll be more careful now.

Thanks.

I did apply light pressure. I'll back off, thanks.

Vk4,

What I am trying to do, is get the best "piano black" finish I can. Super reflective black finish, on an MDF box (speakers.)

Do you have any suggestions for me, mate? :)

I'm using MDF, and will be sanding:

MDF
Primer
Paint
Polyurethane.

Does this change any thing?

What do you mean by "flat out?"

And, thanks!

It is.
What does saw dust do to us?

I dropped out of highschool, so I didn't learn science/biology.

Thanks, LGS.
Another question:
Can I take regular sandpaper sheets, cut a circle, and put velcro or tape or something on it ?

A group of people just told me not to power sand over 220-400 grit.

First question, is this a problem?

Second, is there any way around it? I refuse to hand sand.

Third, even if power sanding...

Huh??
How is saw dust bad for us? *shudder*

Using my block sander, 1/4 sheet.. It leaves marks near the edges of the sander, it's not a uniform sand job.

What am I doing wrong?
(also, this was using 600-800 grit.)

Thanks.

Where can I get high grit sandpapers, in USA - for 5" orbitals? Preferably velcro, but I can get a new sander if need be (stick-on.)

By high grit, I mean 600 - 4,000.

Thanks!

Thanks, guys!

If I get one with a large gallon volume, does that mean I don't need the SCFM the HVLP gun requires?

I only need equal SCFM if I'm doing a "large" project, so the compress doesn't run out of air...

I need a compressor to run HVLP guns, as used for automotive painting.

It does belong here, as I want to do an automotive finish on my woodwork projects.

Any way, what compressors would you...

Hello!
I have two questions regarding planers:

1, This is what I need in order to take a square or rectangular board, and flatten it out - right?

4.000 :oo:

*Delete*

How do you prevent the edges of MDF from rising over time?

Nah mate, I'm using a table saw. It's pretty accurate, I check it with a square before I cut.

However, I just wanted to get that little bit more accuracy. ;)

I saw some power planers with a fence. I just assumed the fence wouldn't be enough support to keep it straight.

But since you suggest it,

Would a power planer with a fence work well for what...

Aww, bummer. Thanks for the info!

Any idea about my above post, and keeping the planer level/straight?

Thanks.
