Spray Painting

[Rockytime]

I have four air compressors, several air brushes and a regular paint sprayer. I don't use any of them as the compressors are noisy, air hoses are a nuisance as well as being inconvenient in my tiny shop. I presently paint with rattle cans with the garage door open. Painting is fine. However, I usually dip my projects in 50/50 BLO. I use a large pan and assist with a brush for items that exceed the pan dimensions. I lay the dipped item on newspapers to drain and then hang them to dry. Someone here posted a video about someone making a basket with a very crude lathe and scroll saw. During the finishing of the piece it was sprayed with a spray bottle. Looked like a good idea. I could make a frame with wire mesh, suspend it over a cardboard box with newspapers and spray the item. The drippings would go onto the newspaper and I could leave the item on the mesh screen to dry. I know there are problems with this idea but I don't what they might be outside of the BLO drying hard in the spray bottle. So what other fallacies can I look foreword to? I hate finishing.

First time I made the 50/50 BLO I mixed it up in a plastic recycled rainX windshield washer solvent gallon jug.. The mix sort of melted and deformed the jug.. It took it several days to do so but none the less it was softening the jug.. so with that said.. Not sure if they have metal spray bottles or sprayers.. depending on the type of plastic it might melt.. and it may not melt the bottle but maybe the sprayer parts of it.. Worth a try though I suppose.. just be aware of this possibility.

They make bottles that are chemical resistant. I have been using these for a few years and the only thing I have found that didn't work in them was mineral spirits. Mineral spirits would soften the o-rings  after awhile.

That might be a problem because my 50/50 BLO is half mineral spirits. I'm also wondering if the linseed oil will harden in the tips orifice. Thanks for the info.

My findings exactly. What holds up the best is Windex window cleaner spray bottles

im not a fan of finishing,too.

let me rephrase that: im not a fan of the patience required for finishing.

i use the blo/ms on a great majority of my scrollsaw work. what i do is instead of newspaper is use old towels to lay the pieces on after soaking. the towels suck the excess off pretty good.

I keep MS in a spray bottle for pattern removal, clean-up etc.  I think it's just one of those plant misters you can get at Walmart.  I've used it for several years with no problems.

Once upon a time, I used 50/50 BLO/Mineral spirits in a spray bottle.  Fifteen years later, I am still scraping small hard droplets off the back of power tools that were in the way of the overspray.  A clean mustard bottle and paper towels work best for me.  Safety note:  BLO polymerizes in air, creating heat and potentially a fire.  Lay those towels and rags flat until the BLO dries.

Don't you eventually run out of towels?

I'm asking out of curiosity. I have been dipping my projects in natural color Watco oil and once dried I shoot a couple of coats of Zinnser's spray shellac on them. So far so good. How does this compare to the blo/ms? Just asking.

I use newspaper to lay the wet items on just because we get a free weekly paper that I use. I throw the wet newspaper in a trash container outside. For painting I have a professional spray booth.

actually no. a couple reasons for that.

1- there isnt much BLO that comes off of the pieces so i hang em up until the next time.

2- i volunteer at an animal rescue that gets a LOT of towels donated and not enough space to store them.

good question and dont really know the answer. when i do BLO/MS only it is mainly on ornaments. thinning it seems to allow the blo to soak a bit more into the wood a bit more. doesnt provide more protection.on plywood pieces it tends to darken up the edges a bit giving a bit of depth. 

adding the MS seems to help it soak in a bit more. thins the blo some.

watco might do the same-idk as i havent ever used it. been sayin for years im gonna try it though!LOLOL

 

sooooo- in other words i dont know how it compares.  i think adding the shellac gives a bit more protection,though.

Watco oil contain Poly and dryers so it actually dries and hardens to a protective finish.  Normally it dries in a couple hours.  BLO does dry but it takes days.

Watco might dry to the touch in a couple hours, but I think it still takes a long time to fully cure.  I used Watco on a couple items I made for Christmas presents.  I finished them over 2 weeks ago.  They were still off-gassing (an indication they aren't fully cured) when I bagged them up on Christmas Eve.

I see the beast folded up behind the trash can...I have one of those too. Hate the fence!

The beast is fantastic if you use the fence correctly. Raise the blade up quite a ways. Move the fence against the blade and lock it. Then keeping it locked  move the fence by sliding the table in or out. In this manner the fence is always locked square. Hopefully I've explained it OK.
