cheap paint removal for engine parts

[2T5]

Apparently too many people died after explicitly not following the directions and using it with no ventilation.

Apparently is a word often used when there's no hard evidence to back up a statement (ie. your talking shit!).

I shall now await notification of being banned from the forum. :-)

Old school Chem-dip worked great at taking the paint off stock 350B carbs.

For cyls and heads, I'd suggest finding someone to blast them. 

Dry bead blast if you're gonna paint em, wet beads (vapor) if they'll be left raw.

Def more expensive than DIY with chems and elbow grease, but the finish is worth it.

To get the polish on the cases in the pic, that requires two blasts in a vapor hone.  The glass bead that gives it that polish will remove some of the paint, but not most of it and requires all the oil and grease to be cleaned first.  You'd still need to vapor blast with an abrasive like aluminum oxide, garnet or silicon carbide to get the paint off first.

These were not painted originally, and just greasy dirty. They got one pass thru with wet beads and came out beautifully.

Yes, but the OP is looking for advice on cheaply removing paint. Your situation is different than what they are looking for advice on.  They will have vapor hone with an abrasive media, then again with glass beads to get the finish you are promoting.

Well, I didn't see them die of toxic fume inhalation!  Play stupid games, win stupid prizes!

Jasco, back in the day was the bees' knees. That stuff took your skin off if you were not careful, and sure as hell removed paint with ease. Now, pffffft. Two years ago, or so I stumbled across pti stripper from aircraft spruce. Ordered a bottle, opened it up and it stunk like high heaven, but doesn't have methylene chloride which was the cocktail of choice back in the day. I quickly applied it, before the epa got a hold my address, to the original paint on my 75 and it ate the paint away like magic. I just checked their site, it's still there but looks like the epa got wind as I don't think u can order it anymore.
They shipped it in a thick plastic bottle. I didn't use all of it, put it back on the shelf. Maybe a month later I look up and the damn bottle was about to explode. Bunch of numb nuts!
Oh well, good luck.

Actually I take it back. The cyls and head were painted and the cases were raw.

The cyls and head were dry blasted only, and the cases were wet blasted only.

The polished bit on the head/cyls was done with wetodry sandpaper and polishing compound.

Yep removing paint cheap and easy is pretty much my question. So this topic I can see as very informative. Perhaps more importantly,supportive on the reality of what can be done or more like the lousy results of what can't be done with most available paint strippers.

I did get some baking soda and white vinegar just because I thought it dirt cheap and I can always try it for household cleaning. I dunno what to say except I would like to do a nice job of it but realistically the cylinder heads were just some mismatched set I paid over 90$ bucks for on Ebay. The most visible parts being the polished outer side fins while whole and intact one of them has a slight bend to the side and the other one has a little wave to it in the middle. They are just not perfect but the plug threads are good and they look flat where they will bolt on the cylinders. They were the most affordable and workable cylinder heads I could see offered for sale at this time to mate to those cheap Chinese cylinders. I just see if I can soften up what bit of paint is peeling away with this cheap paint removing cocktail and get inspired with elbow grease and scraping tools.

I may get that Berryman chem dip but I may also want to line up a bigger order of things to paint strip(assuming you can reuse it) if I spring the 40$ bucks for it. Heck I may not even repaint these heads, just wanna remove the loose paint that's left and polish the outer fins. I know once it's all put together I'm gonna have to look hard to admire the fresh paint and finish otherwise.

keep in mind the mek and other chemicals, the nail in the coffin so so speak on those,  was that they can permeate the blood stream thru the skin, the molecular size is small enough where it can do that.  so, yes, worked awesome but, yikes.

I was able to get real MEK at West Marine to use to strip gas tank liner out.

OK I will hang myself to dry by first saying that I really need to get more into my postings and add pics. OTOH although I am a bit chuffed with myself...but meh it's not that really big a deal but I am progressing. Today I went to work on stripping the paint off my cylinder heads. Took a bucket and filled it with a 50/50 mix of hot tap water to white vinegar (7 quarts altogether) and added a 1/4 cup of baking soda as advertised as a Google answer. Now the baking soda may not of been a good idea as I guess it neutralizes the white vinegar according to some very knowledgeable women of youtube. However I think they were more geared to home cleaning solutions and besides the combo did this awesome white fizzy action for a few seconds.  Next I submerged the cylinders into the bucket bath and let em soak for six hours before I could get to em. with a sharp three sided deburring knife as well as a cheap fish cutting knife and some 120 grit sandpaper that I had I just started to scrape away some very soft pulpy paint. I'm not done yet and the cylinders are still soaking.

It is a bit labor intensive and slow progress but the paint really wants to come off and the stripping solution is very mild to my skin. I didn't even wear gloves although maybe I should have,other than a open scratch that mildly stung a bit and some dryness to my skin I'm totally used to that. I feel way better about using this in that regard than messing with toxic chemicals although I would of liked the thoroughly fast results. Honestly if the surfaces were all easier to get too,flat this works pretty easy and cheap. I do need to search for something that can get into between the fins in and around the bolt holes,bottom of the top of the cylinders.

I just gotta get creative and be patient and that's ok because the weather here in NE sucks.Rain and freezing rain showers for the next five days today temps were at or below 40 degrees. March in like a lion and out like a lamb.
