green jukar rifle

[der mike]

I have an old jukar PA longrifle that has turned green, any idea what happened? How can I fix?

[Captchee]

the stock has turned green or the barrel has turned green ?

 eather one calls for stripping and starting over .

Green Stock = Chromium Trioxide.  Normally I'd recommend stripping the finish and sanding/scraping off the stain, but I'm not sure if it is toxic in its cured form.  Maybe someone can advise.  Green barrel = Cool; I'd like to figure that out .

      Chromium Trioxide, as stated above.   Hit the stock w/ a can of paint stripper, clean it down, re-sand, re-stain and you are back in business.  Plan "B" get a few cans of brown, tan and black paint and make it camo......

Toxicological Data on Ingredients: Chromium Trioxide: ORAL (LD50): Acute: 80 mg/kg [Rat]. 127 mg/kg [Mouse].
Section 3: Hazards Identification
Potential Acute Health Effects:
Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in case
of skin contact (corrosive, permeator), of eye contact (corrosive). Slightly hazardous in case of skin contact (sensitizer).
The amount of tissue damage depends on length of contact. Eye contact can result in corneal damage or blindness. Skin
contact can produce inflammation and blistering. Inhalation of dust will produce irritation to gastro-intestinal or respiratory
tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking,
unconsciousness or death. Prolonged exposure may result in skin burns and ulcerations. Over-exposure by inhalation may
cause respiratory irritation. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is
characterized by itching, scaling, reddening, or, occasionally, blistering.
Potential Chronic Health Effects:
Hazardous in case of skin contact (irritant), of eye contact (irritant). CARCINOGENIC EFFECTS: Classified A1 (Confirmed
for human.) by ACGIH, 1 (Proven for human.) by IARC. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells.
Mutagenic for bacteria and/or yeast. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available.

 I may be wrong, but I have been led to believe, that Chromium trioxide is not a surface stain. Isn't it much like auqafortis, which is an acid stain, that is in the wood, not on the wood. What I'm trying to say is, I don't think any kind of stripper is going to remove this green color. I have most often found this green color is the results from not heating the stock  after applying the chromium trioxide, or not heating it enough. Your course of action will depend on what finish is over the green layer. This may be a lot more work than you want to put into a very inexpensive rifle.

Several years ago a fellow stopped by the shop with rifle #4 that I had made years ago and stained with chromic acid.  It was as green as the grass in my yard.  I ask him to leave the rifle with me for the week he was on vacation and pick it up on his way back home.  Once he left I simply used acetone to remove any oil or wax from the stock, did not strip or sand away any of the finish, and just restained the stock with a mixture of orange and yellow Sherman-Williams dye stain concentrate.  That stuff will penetrate almost anything.  When he returned at the end of the week his rifle was a beautiful reddish brown color  with no trace of green.  He (and I) were most happy with the results.  I think the dye stain concentrate has been discussed here in a previous thread.

According to Chuck Dixon,  the problem is when Chromium Trioxide has been used in a dilute form.

    I have refinished a number of rifles built back in the 60-70s that degenerated into a greenish cast.  As Jim said just re-stain with something like LMF Nut Brown, after thoroughly removing whatever protective finish is on the gun.  I like to use Aircraft stripper available at Auto Parts stores, as it will remove most any kind of finish including epoxy finishes.  Using stripper eliminates almost all sanding dust except for a quick cutting down of the grain raised by the removal process.     Not much expense involved and good practice for a neophyte.

thanks all for your output. The stock has or was green,not ugly,just green. True it was an inexpensive rifle ($80.00), but a great shooter.

I will try my hand at a faux curly stripe.  thanks again............mcp
