Chainplate inspection

Hi all,
Since we have the mast unstepped this year, I was determined to remove and inspect our 26-year-old chainplates. All 6 of them (3 per side) came out with no problems, and we have them at home now.

So now that we have them, how do we clean them nice really well so we can inspect the surface completely? Just not sure what the best product or process might be. There's some surface rust in some spots, but nothing obvious without cleaning them up to really look at them.

Any suggestions?
Thanks!

Scrubbing them with a scotchbrite pad will remove the surface rust and let you inspect them.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Why not get them professionally crack tested. It is not that expensive.

Just about any enginering shop will do it.

I was considering something like that, since I went through all the trouble of removing them!

Anyone know of a place in the Annapolis area where I can get them checked out?

I use a buffing wheel. If you own a 6 or 8" bench grinder you can buy cotton buffing wheels for them right at Home Depot and the polishing rouges.

My buffer came from Harbor Freight, on a whim. It basically sucks but for the amount I use it it struggles through. It will eventually burn up then I can justify a real buffer like a nice powerful Grizzly..

As for dye penetrant testing you can buy a kit and do it yourself or any machine shop can do it for you.

Before:


Buffer, Tripoli, Stainless Rouge & Chain Plate:



After:


Not bad for 31 years old!

Looking good, Maine Sail. I don't have a buffing wheel, but am not opposed to getting one.

What are the products in the pic you posted--the "green" and the "brown"?

The brown (actually reddish brown) is a tripoli rouge. It is a good first step compound for stainless. I then follow this up with the green which is a finer stainless steel polish that leaves a high mirror polish. Ryobi has a section at Home Depot and they have a tripoli as well but their stainless rouge one may be a different color, can't remember, just read the labels. This tuff is cheap two sticks of rouge and a 6" or 8" wheel will run you about $12.00 - $14.00..
