Carburetor madness by Drew

[Heo]

I was offered some flathead pistons on a swapmeet. But he just had
four of them with him beacuse he had to rebuild the other four first.....
Me -Rebuild the pistons? how do you rebuild the pistons? He- Ohhh its
easy i just glassbead them look here they are just like new.....
Thank you but no thanks i buy new ones

Definitely watching this thread and making my notes.Difficulties start when I'll start translate those.

Plain zinc gets gross in short order.  Aluminum gets cloudy, I prefer it sealed.
I used a blue dichromate.  The pictures don't capture a tiny amount of iridescence.

8 hours into this one.

Will assemble tomorrow.

This is a Holley 4011, List number 84014

[Drew Pojedinec]

I sold that 4011, so I got bored and built my larger plating station. 
Some linkage
Bead blasted to get a finish.

I dunno how to do a step by step with this software.... dammit photobucket.

Anyway, I built a larger plating station.  I like a more dull than shiny finish so I'm working on that.  I shouldn't have strung all the pieces together as I got some shading as you can see in the later pictures.

I figure 25 milliamps per sq inch, so I ran this at 125 for about 8 minutes.  After plated I dipped it in phosphoric acid, water washed, than dipped in yellow dichromate and rewashed with water.  Just trying to get the larger station and rectifier figured out.

That last picture of the accelerator pump arm.... see how the zinc didn't hit it all?  that is shading where that part didn't "see" the anode.  I shoulda strung them up seperately and wiggled them around a few more times to make sure it all got covered.

Yes that whats happens if two surfaces is to close together it wont take there
like inside a pipe  I thougt on the small pics you had catched a crawfish in the
orange bucket

[Drew Pojedinec]

Lars, this is the deep south swamp lands.... there are ALWAYS bugs.  Always.  Leave an engine open long enough and there will be bugs making nests, just how it is.

Anyway, now off to plate everything I own until I get it perfect.  Least now with the big tank I'll be able to plate a whole main body if I need to, before I was very limited due to rectifier output.
I'm sure Torbjorn could add more to this as he is about a year further along on this journey than I am.

[Heo]

Well i guess in the swampland you need ewerything zinkplated so i dont start rusting

[Drew Pojedinec]

Not perfect, some splotchiness, but getting better with this larger tank

Before and after 4777-3
I guess if no one has any specific questions this thread is dead.

Next mission is add some brightener and see if I can replicate the shiny yellow dichromate appearance like on new linkage or grade8 bolts.  I prefer dull finishes myself, but ya know, opinions.....

Darn Drew, that looks almost new.
Really nice.
I'm interested in what you're doing but just reading and learning.

Ok cool.... didn't wanna be shouting into the void (again).

Next time I'll show how to install boosters.

[Gregwill16]

Nope Drew looks great and some of us are loving it and just waiting for you to offer up your service lol.

[Drew Pojedinec]

Good good, I just didn't want to be spamming the place if there isn't much interest.  I'll keep documenting the more interesting projects here as I go along this path.

I haven't felt the need to offer my services due to demand.  Plus I'm still very much a novice and really need to do a few dozen more to where the results become more predictable.

Drew,
I'm here at least once or twice a day.  I read everything, but usually don't comment.  I'm pretty much a noob when it comes to building hipo engines; I'd rather read and learn than chime in with a bunch of useless "me too" type posts that don't add to the discussion.  I enjoy what you write, and this thread about restoring carbs is really interesting.  Don't stop.
Take care,
Dan
