Not everything can be sprayed. It is important to be competent in multiple application methods. In fact, my professional experience is that guys who understand brushed finishes tend to have a much better sensibility in sprayed applications.

For the purposes of archiving and reference, here is a pretty thorough article in the March 15 JLC magazine, about paint brushes:

Wanted to make sure FOG finish enthusiasts could access it going forward. I am happy to discuss any questions related to it.

Happy Finishing.
 
Scott,
Thanks, this is really helpful.  Nice to know I was generally on the right track when matching the sizes and shapes to the job, but why is the square corner ferrule better for the small brush?  You didn't really address it, but if for oil based paint or a clear oil finish, what do you recommend?

Thanks, again.  I really learn a lot from this forum.

Glad to hear it, Mike.

The square ferrule design makes for a narrower bristle pack, so the brush has a smaller tighter feel.

Here is a picture showing a square versus oval design. You can see that the oval is a much bigger brush, even though in brush nomenclature it is only 1/2" bigger.

The Syntox by Purdy or the Arroworthy BristleOx are a couple of the brushes I use in oils.

im a big fan of anything with dupont Chinex bristles.. they just clean so nice!!    my father is a professional painter and swears by Picasso brushes.. although i have heard from him in the past that they are a bit hit or miss on the quality  either excelent or crap.  not sure if they have sorted that out yet..
nice write up!
 
Here is a new link to the video... previous one suffered death by app snafu...

Scott, in the pic, one brush (the square ferule) is loaded with paint and ready to go to work.  The other brush looks as if it has recently been cleaned.  Not "apples to apples" display.  [unsure]

Scott, I'm no painter other than when I was learning the trades back in my late teens and early twenties, i'ld get stuck with a lot of the painting >>> and, to put it mildly, disliked the job.  As I remember, the bristles would remain sort of fanned out and kind of loose until loaded with paint.  That was back in the days of oil and lead paint.  I always used my own brushes as i would always hang in a bucket of "terps" over nite so they would be clean and dry two days later.  I always kept enough brushes that i did not have to use the same brushes the next day. i think, because i hated painting, i was being lazy.  Being lazy made the job easier and less revolting.

One of those i learned from was probably the best painter in the area.  I marveled at the way he would paint sash.  In those days, a window with small panes was just that.  Small panes of glass separated by wood (don't remember what those strips were called)  He would load up a 3" or 4" brush and with one stroke, hit all of those spacers on one side of each, a second stroke the other side, third stroke one side of the next and so on till all of the verticals were done and then start on the horizontals the same way.  Then the top of the frame and the bottom, then the sides.  BING! the entire sash would be done using one dip of his brush into the bucket in the time it took me to just think about how to load my own brush.  When he was finished there was always about a 1/16th inch bead around every pane of glass.  never more and never less.  When i was done with my sash, there was plenty of work for my razor blade around the glass.  I have never seen anybody do windows that way since.

I did not have time to check out the latest vid, but will do later today.  I am, in spite of myself, learning a lot from your demo vids.  Good job on all i have watched.

Ha, that's a good one, Tinker! That may be the ONLY situation where that square ferrule will spread more paint than the semi oval!!

Yes, I thought of you as I was editing down the hours of vid footage from JLC...glad you (and others who didn't come) can at least check out the highlights reel.

You don't have to like painting per se to still have an appreciation for the crossover between carpentry and finishing. They overlap now more than ever. It was great time at JLC, especially in the classes we taught and on the exhibition hall floor...

Definitely post up your feedback after you check out the video. You asked that we turn down the music and let our voices be heard. The sound is not world class, but I did caption the heck out of it and keep the music to a minimum.

Happy saturday.

I usually go with a 1 1/2" angle sash on dentil...
 
scott, Just recalled an experience i had with painting back when i was often the paint crew on jobs.  I was working for three brothers who did almost everything on their houses except the plumbing and electrical. One of the trades they did by themselves was the painting.  I think that was when i first started to develop my dislike for the project; as I was the electee for most of it.

We were coming close to completion on a low ranch that was wood shingle siding with light green stain finished (Oil stain?).  I had completed all of the staining all the way around except for the bottom three couss along one side of the house.  the wall was maybe 40 or 50 feet in length.  This was way back in 1950, so since I am only 39, I don't really remember things like distances so well. I had just finished a five gallon pail and was about to open another when the plumber stopped by.  The middle brother, who I worked with mostly, and I were the only others on the job; but the plumber had a full bottle of scotch that he felt he needed assistance to find the bottom of.  I was under age, for such, but in those days, I had a taste for such things.  I did not drink when out with my peers, but when home, i was always allowed to sample. 

This particular afternoon I was quite willing to assist in emptying my share of the bottle and was the one elected to "take the poison off", which I was most willing and enthusiastic to do.  I don't recall how much of the scotch the three of us had, but we each took several swigs.  I probably had least my share.  I did go back out to finish staining those last rows of shingles. I had never drand the hard stuff while working altho, when I was younger, i had always had a good sampling of beer while working in the hay fields.  I hated coke and pepsi, but that beer sure tasted great. I must have felt I could handle the Scotch as well as I had always handled the beer.  i expected no pay back.

Since the last rows of shingles were low, i had to bend down, ether by bending my knees or bend from the waist.  I was in a great big hurry.  I had a date to pick up my girl friend right after work at slightly after four thirty.  i was already running late, so i just grabbed the 5 gal pail and large brush and started in.  i was holding the pail in one hand and brush in the other and bending from the waist, never letting the bucket settle to the ground, i sailed along, never straightening up for relief until I got all the way to the end of the three rows.  AS I finished the rows, i straightened up.  That is, i forced my back to go straight.  My knees had been straight the whole way. As my back straightened, and my knees were already straight, my entire body just continued the momentum until all was straight ... and lying flat on the ground.  The bucket of paint was not yet empty and since the hand that had been holding onto it seemed to have suddenly lost its authority, the bucket decided to have a mind of its own.  It just kept on going in the same arc as it had started as my body went its way. 

When all came to a halt, I was covered from head to feet with green stain.  The can of turpentine that was on hand for cleaning the large brush was no where near enough to clean everything.  I guess I got most of it off of my face and maybe the seat of my pants.  Heaven forbid that I should get my car stained.  I could get covered with anything, but my car-----!!!!!  I did manage to pick up my girl friend and she got a good laugh about her green monster.  Her mom wasn't so happy about my plight, but after a few harsh words to her daughter, she got to laughing as well.

Well, even tho i did not like painting, the experiences i had with the trade had left me with many tales to tell after i got to be 39.  the big trick was to actually live that long. [scared]

Funny story, Tinker! Sounds like the staining drove you to drinking. And the drinking made you stain yourself! Many paint tasks are repetitive. It works out for me because I have excellent muscle memory, and a rich inner life!
