oil on blank from compressor

Hey Guys

Just finished shaping a Marko EPS blank and notice some yellow spots on the blank in a few places.

At first I thought it might have been from my garage leaking a few drops of water. (we've had a lot of rain lately)

Then I thought it might have been sweat dripping off of me while shaping.

But I realised that I blew down the blank with the airline.

It shouldn't have been a problem as I have a filter on the compressor but thats what I have put it down to.

Any suggestions as to what I can do before I glass to try and stop me having issues later on?

Cheers

 

can you lightly sand them off? or are they too deep? or paint them into yellow poker dots or something?

 

I stuffed up a black spray job on a board i just finished, tried to sand it off, and the whole top of the board ended up gray!

Ditto.

Yer I will give it a light sand and see what happens.

I sealed the blank so it needs sanding anyway.

Cosmetics I'm not too worries about, just dont want any delams.

Cheers

 

Remove the inline oiler and replace all of the piping/tubing down stream of it and the hose. Or break it down and clean all the oil out of the inside of it. You need dry, clean air. Then you will need to oil your air tools manually with 3-5, no more than 7 drops of air tool oil directly in the quick connect on each tool every few hours of use.Don’t use too much or oil will bleed out of the air exhaust port.

Oil on the raw foam usually needs to be planed off to get all of it. Make another pass, re-blend the rails and refinish. Yours is sealed so maybe a sanding will fix it up. Good luck.

 

 

i was worried about oil from my compressor and instead use the shop vac to blow my boards off…

never had a problem… hope you get it worked out, i’d be worried about delams too

black and white ,in color science,make?

 

grey or sometimes gray.

but it is always half way

between your white and ah,…black.

case closed.

 

if you wanna get a true black

try another coat of pigmented -

covering of your choice.

 

for the most true black,

turn off all lights,and

block all light sources.

true black is simply the 

absence of light

in reflected light science,

one of color theory’s two kinds of color,

reflected and projected.

…ambrose…

remember there is no such thing as 

a projected black spotlight.

…yet… maybe thats a gift

to think about for 

somebody on april 1st

maybe for a millionaire

A few drops of oil might be a big problem when glassing. The dreaded Fisheye and a poor bond are distinct possibilities.  Sanding might further spread the problem across the blank.  Do a sample of the oil drops on a scrape piece of foam try soaking the oil spot with a degreaser compatible with the type of resin you are using then apply a small amount of resin over the spot and see what happens. If all goes well then try it on your blank. If not try another degreasing agent.

To add what Ozzy said, MAKE SURE YOU ALWAYS DRAIN YOUR COMPRESSOR TANK. This is something I do daily for my woodworking tools. With a fluctuation of temperature, you'd be surprized at the accumulation of water in the bottom. The condensation causes this and is bad for everything related to the compressor. Set up a water trap in line. Unless you are using pnuematic tools all day an in line oiler is not needed. As Ozzy said you only need to oil the tool you are starting to use and lightly: "3-5 drops" is all. This is only to coat the inside of the tool and piston to keep moisture off it. Leave the petcock valve open overnight, don't keep pressure in the tank when not in use. Of course, in freezing conditions, close the valve.

      Howzit tblank, I would drain my compressor tank at the end of every day and was amazed at how much water was in there but that was Kauai where the humidity is through the roof. I had an oil belt drive compressor but had the hoss coied about 15 times over a rod and never found any water or oil in the seperator or filter so the oil must have collected in the bottom of the coiled air hose is the only thing I can think of. Now I have my Senco nail gun compressor that also uses oil but since I had to get out of the business I only use it for tools and I only put 1 drop in the tool and if using it constantly I put another drop in every hr or so. I also have one of those small Senco compressores hat is oilless but doesn't put out much CFM's . Aloha,Kokua

Hey Kokua Aloha! Yeah the little Sencos are tempting, they are sooo lightweight. Hate lugging around the twin tank 1&1/2 hp. Emglo ( small one, the wheelbarrow type only comes out for a bigger framing job) but I've got to stay with the oil sump units. The oil less ones don't stand to daily use over long term. I want one of the Sencos like yours but I can't justify ANOTHER compressor, I have too many now.

 

ps. "Get your motor running, Head out on the highway".

I've got a feeling Wildog is coming back with a vengeance! Congrats Man!!!!

     Howzit tblank, I don't think the small Senco puts out enough CFM's for painting and I hate those loud oiless compressors that use 15 amps to run. For painting I really prefer a belt drive oil compressor because they are quiet and use only about 7 amps to run. I guess I could just use the big Senco but it is loud even for a oil drive compressor or just find a good used belt drive for sale. I am going to do some gel coat repair on my nephews boat and will do a test with the small senco to see i it has enough CFM's to paint the gel coat. One thing I know is I brought my filters and oil seperators with me in the move so I have what I need for the fix. It's a teal background with a purple overspray around the edges so no big deal. Aloha,Kokua

Hey Guys

Well, I'm having second thoughts about it being oil. Sanded it and it didn't budge. Glassed the board and no problems at all. Its actually a flouro yellow color. I have no idea!!!!. we'll see how it goes i suppose.

Cheers

 

       Howzit mds, I hate to bring his one up but is it possible you might have a rat in the room that peed on the blank?. Aloha,Kokua

The thing about oil stains, sanding or screening might get some of it, but you will probably just keep scrubbing it down deeper. I can’t say for sure because I went to great pains to set up my air system to be dry from the start. Large water filter, good regulator, low point drains, and a second filter and regulator for the lower pressures of painting and air brushing.

maybe where they live it was a squirrel ?

summer’s comin on…

saw mez yesterday

his shop is set up in anahola

…ambrose…

Good call Kokua. Been There Done That.

     Howzit Brother Brose, Heard he lost his house in Haena and it was a bummer since he had the shop dialed in for doing anything to do with wood work or shaping boards. I know he was not happy and the rent in anahola is way more than the deal he had in Haena with the Batty Family. I am sure they probably have it up for sale since they sold one of the house on the mauka side and the big estate on the beach. Danny Durone's son Danny ended up moving into Mez's house and I wish I could get the hole story from Mez because Jim Pubons told me the Batty's more or less screwed him and Celia after all the years they helped the family, but since the Dad and Mom have passed away and the sons now are in charge they just want to cash out and divide the money between the 3 brothers. I also heard Mez sold a lot of his tools and I would have loved to have been there for that sale since he had every tool on the face of the earth. Next time you see him tell him Aloha from me since I don't have his email address but I can try his cell phone.  He is one of the best guys around and working with him was always great. Aloha, Kokua

Hey Guys

Well its still got me beat, but I did see the same color stains on my shirt. maybe it was something I ate that day.

I always make a point of washing my hands before I touch a fresh blank.

Maybe I forgot that day.

Cheers
