Source for Backing Plates

[Mark Wolf]

I'm interested in finding a source for Stainless Steel backing plates. Thanks

backing plates,ect

Do a search for onlinemetals.com. They'll cut to size and have many choices.

You might try the scrap metal dealers in Baltimore.

Do you want to cut/drill this material yourself?

If you don't want to do this, then I suggest you contact someone like Garhauer Marine. You can send them a diagram and they can handle it for you.

You can speak with Mark or Guido.

For backing plate stock wouldn’t aluminum do it is easy to cut drill etc. 1/4" stock is quite substantial and I have never seen any electrolysis problems arise from matting up the two.

As long as it stays/is dry any metal combination will work. getting it wet won't hurt allowing it to stay wet will.

the big box store should have al. flatbar less than $20 for 4 feet

Fiberglass can be laid up into thick plates and cut to size. Locust, white oak, coffee tree, red mulberry, red cedar(virginia juniper) and black cherry wood is all very durable and easy to work with.

Why not Starboard?

If you are going to use the above materials, why not Starboard? It seems like a lot less work, unless there is something wrong with the material?

For an easy approach, take your 'part' to a local 'welder fabricator' and get an estimate for your backing plates. Choose one that does 'general repairs' and can 'whip-up' a suitable backing plate in a few minutes. These folks usually have tons of scrap sheet of suitable thickness/gage and the proper press brakes to do a fast/cheap job. Just go in and ask "how much"?

Starboard isn't a stable enough material to use as a backing plate. It will cold flow under pressure and loosen with time.

Starboard is not reinforced. Not advised for the above reason also.

I have been using G10/FR4 fiberglass plates, in various thicknesses, from either a local plastics supplier or from McMaster-Carr on line.

Thanks everyone for their insights and directions. I will go with Stainless or Aluminum from one of the suggestions made. I shy away from using wood due to the high loads and shear...the 105 is a wet boat as well with low freeboard...after many, many years of bright work I would be happy without any wood.

If you will do aluminum, check at a shop that makes duct work. Often they punch holes out of aluminum plate to make pluenum chambers.

Try this for metal stock- http://www.allmetalsonline.com/

Aluminum is easy to work with.... you can cut them out with a jigsaw ... but stainless is another issue... If I were you and wanted stainless, I'd send a pattern to Garhaurer. They make backing plates for their stanchions and probably just need the bolt patterns to adapt them to yours.

I needed some heavy stainless backing plates for the keel boats on my C&C. Kato Marine fixed me up. Best looking part of my bilge. As well as having various thickness of material in stock, they have a water jet cutter and can make easy work of it. If I'd had to cut those myself, I'd still be at it.
