I am after some stainless plate about 4-5mm thick in 316 marine grade but it needs to be the polished stuff like the rails on my boat

I am after enough to make about 6 x 2 inch circular discs, I have a company local to me who can laser cut the discs to size then laser cut a key hole shape in the middle of each disc but they don't have 316 marine grade stainless in the polished form so I need to supply them with it

This is for my project of fitting the chocks to my swim platform to put my rib on, so can anyone suggest a place I could buy some from but obviously I don't want to have to buy a 2m long sheet

Cheers Shawn
 
Buy laser or waterjet cut from a processer that holds 316L Mirror finish in stock assuming you know the size and shape you want its job done.

Its one thing polishing cut edges but don't bother with polishing un polished plate its a paint in the rse without the proper gear .

yes but where can I buy 316L mirror finish from this is what I am struggling with
 
It looks to me like you're aproaching this the wrong way unless I've mis-understood what you're want to acheive. If you get them laser cut you'll have to polish them after as the laser cutter will leave burn marks around the circumferance and cutting a keyhole will leave more. In my opinion oit would be better to machine (turn on a lathe) the 50x 5 mm discs and either machine or laser cut the keyhole pattern and laser cut after. Bear in mind polishing will be a lot more difficult after laser cutting than machining.
 
I've just been through a similar process Shawn. I found getting the material of 316 stainless flat bar (70mm x 5mm x 1000mm) was easy enough at prices averaging £25. But to have it mirror polished was the harder bit and more expensive, about £100+. I did find a polishing firm on trading estate in Lye (midlands) and he was happy for cash in hand, so £20 well spent. Not sure if location is any good, but happy to forward details to you if you need.
 
thanks sharpness I will bear that in mind

why is nothing ever easy why cant I just buy some 2 inch mirror finish stainless discs with a key hole fitting in the middle ggggrrrrrrrr

something like this that was on a princess boat at london boat show, but with a round discs not square

Try oval stainless at west Howe near Poole probably the easiest is to send them the one you photo graphed or template

They come up on Google, have a website and display at Southampton boat show.

Why do you specifically want a keyhole style fitting.
Like most boats, I've got fittings like this that were fitted by the factory but we don't use them.
It seems to me that they are harder to use and more prone to being accidentally knocked out.
You've seen how my ones work and thats how we've been fitting our dinghy for several years now.
IMO the simple approach works the best.
BTW - I think a square plate would be harder to cut neatly into the teak than a round one.

Another important point.
In my case, these fittings are just for locating the chocks and have no "tie down" strength.
In other posts, I have explained a "screw in" eye for tieing down.
In this case, I arranged bigger bolts to bolt right through the bathing platform and fitted huge penny washers and extra thick nylock nuts underneath.
 
mike I want the key hole fitting because I will be launching my tender manually so basically pushing it of the chocks and I don't want to risk loosing the chocks into the sea when launching as I have no means of lifting the tender on or off it will all be done manually that's why I am going for a ribeye tl260 and a 5hp 2 stroke motor so its nice and light

I will be using the same sort of tie downs as you have with the eye that screws into a thread, also the picture is a square design but I will be using a 2 inch circular design so I can get a 2 inch hole saw to match the size of the discs
