My first impression of the Nitchi brand was it is a lower budget make.
However, Nitchi was also a Japanese maker until June 30, 2023, when it was liquidated. I can't say for sure this is the Japanese maker, but I'm saying it is, so there.
Here's a link, to the still active page, on Amazon.
No matter, it'll do what I want, and it makes for an interesting project, for me, to use and abuse some accessories I've collected, and I can see how well each performs, without destroying something expensive and delicate.
I removed the faceplate, as it was grubby, bent and beaten, cleaned and will be refitted.
This is the condition of the block when I got it.
I've followed a number of threads about, rust removal, as I've got lots of metal with rust on it.
I thought I'd try the recipe on this post, I used Citric Acid, Sodium Hydrogen Carbonate (Sodium Bicarbonate) and Cocamidoprpyl Betaine as the Surfactant (because I have it for use with another process)
I didn't want to just clean the chain, and other parts, I wanted to protect them from rusting again. I have heard, and had success, with placing the pieces in an oil bath.
But that always works best if the items are warm/hot. So, I came up with a cunning plan.
Rinse the parts as they come out of the bath, and place them into hot water, already heated to boiling in the pressure cooker (that's approx 100 degrees)!
Well that went well, little chance of flash rusting, no exposure to air. I then returned the pressure cooker to the stove, brought it up to boiling with the lid on and closed the valves, I'm now going up to 120 degrees. However, we've got an induction hob, this thing is going to heat the pot AND the chain!
Anyhows, boiled it away at a fair rate for about 20 minutes, getting everything to heat soak. Now to drop it in oil.
Set up a pole, on the top of my storage rack, clamped in place, to drape the chains over and allow them to drip into the bucket.
Bucket prepared with some spare oil, was marked a for a Hydrovane Compressor (can you tell I have a compressor problem), hope there's enough to cover the chains in the bucket.
Taking the chains out was a delicate job (burnt fingers), so used a couple of pegboard hooks (you can see them, sitting on the shelf under the belt sander) to grab the chains and transfer them to the oil.
The chain, flash dried in seconds, then into the oil. Plenty deep as they were fully submerged. I was right about the chain heating up on the stove, took longer than normal to drop pressure and get the lid off, and the water was vigorously boiling. Not just from the pot, this isn't a top quality pot.
Out of the oil and hung above the bucket, did both chains, the heavy lifting and the one you draw to winch the blocks.
You can see the difference the bath made, they've been hanging there for a day already and they look the same. They'd be there for a number of days, I've nowhere else to put them. I'll rag them down later and dry them off a bit.
The chains were in the bath for 40 hours and 14 minutes, that's what the stopwatch says.
The rest of the winch will be added to this thread as I get it cleaned and prepped for painting. I'm waiting on a paint delivery before doing surface prep, at least get an undercoat on the coloured parts. Will be taking all the bolts to my 'Bolt Emporium' and getting new.
