bench hinges
 
I am getting a qoute to replace my bench seat hinges. the originals are aluminum. I will be upgrading to stainless. I am going to eat a pretty large fixture fee for this. So if any one has already done this, I would be very intrested.

any reason in particular why you're upgrading? Let us know what you find out!

Hi tfn1977,

I had to have one hinge made as our rear bench consist of three individually hinged cushions and the middle hinge was missing so I had it made from SS as the existing aluminum hinges were corroding and looked weak so I wanted to see if the SS hinge would be better.

Can you post or send me a picture of your existing hinges? If they're the same as mine (they are a have two pivots and three plates), I might have a little trick that may save you some bucks...

I'll try to get a picture of the hinge I had made when I can.

This is an old thread, but I'm hoping to get some help.. The hinge in the picture is exactly what I need. Three of them, for my bench seat, which is falling apart as a result of the hinge corrosion. I have the PC Talari, 246 special edition. The hinge is about 9" long.

Does anyone know where these hinges are available, or how they can be made, or what needs to be done to replace them?

Much appreciated, as I have been to every hardware and boating store in the state..
The boatiung season in Rhode Island is short, so I'm hoping for help..

Re: bench hinges
 
Hello All, For anyone who is interested in the bench hinges previously pictured in this thread, there were three offset hinges on the bench seat of my Mariah Talari PC 240, and the aluminum hinges corroded.After searching unsuccessfully for original replacements, and looking at what others have done4 on this website, my solution came to the following successful conclusion:

I replaced the three broken hinges with six offset hinges, welded in pairs, purchased from Veada Manufacturing. Look on their website for offset hinge model HA201H5. The website is Boat Hinges and Pedestals

The hinges from Veada are only 5" long, and the original hinge is about 9" long, but the Veada hinges are more sturdy, and they will work. Also the "ell" on the Veada hinge is .25" longer than the "ell" on the original hinge, but this is not a critical difference, especially if you replace all three original hinges (recommended..) Anyway, bring the six pairs to a welding shop, it will cost about $20 to have the three pairs welded. It's quick and easy. Make sure the weld is done so that the two "bumps" on the new hinge match the orientation of the original hinge. Take the original hinge off and match them up!

When you are removing the original hinge, you may also come into the problem with the T-bolt that it screws into is corroded! Unfortunately the T-bolts are not stainless. If the T-bolt is corroded, you must remove the vinyl covering the opposite side of the hinge, so you can replace the T-bolt.

The other option, beside replacing the T-bolt, is to Drill out the existing hole with a 3/8 or larger drill bit, and used a stainless steel "threaded insert" (hardware dept in West Marine, not avail at most hardware stores..). Screw the insert in, and then you can attach the hinge to the insert with a stainless bolt and washer. Be careful, when drilling out the corroded T-bolt, that you do not puncture the vinyl on the other side. You may want to stick something in behind the vinyl, if you can, to push it away from the drill bit's sharp tip!

OK, so you have the welded hinges, and the T-bolts are either in good condition, or replaced by stainless inserts, so now you can attach the hinge. The new hinges are only 5" long with 4 screws, instead of the original 9" long with 6 screws, so you will have six unused screw holes on the bottom of your seat.. don't worry!

The final complication which you will run into is the separation betwoon screws on the seat is about 3/8" different than the separartion between holes on the hinges. Therefore, mark the spots by lining up the new hinge over the screw holes, and drill a hole to widen the gap on the hinge, where neccessary. The hinge is aluminum, very soft to drill thru, so it's not a big deal. Then attach the hinges over the srew holes using the proper size bolt, and a washer.

Tedious work, but nice results. I hope I saved someone some trouble.

I have pictures of the new and old hinge, but don't know how to download them, but the old hinge is the same as that on a previous post in this thread, and the Veada website has a picture of the piece used for the new hinge.. good luck!

Hi Sweetdreams, please take a look at this tutorial (click here), hopefully it should help you with posting your pictures (sorry if the illustrations look a little different, this tutorial was made from our old Forum format, I'm working on new ones). If you still have trouble, send me a PM and I'll see what I can do to get your pictures up here.

Re: bench hinges
 
Another idea if the center section is still good...... Purchase new 3 inch hinge. Aluminum or stainless , cut to length, punch out the pins on both the old and new hinges. You can bend or break the tabs on the old outer sections and the pins come out easily. Now using each half of the new hinge outside the old center hinge section, reinstall the pins. Then the only challenge to this or the other post is in bending the new sides to the same 90 degree shape as the original. I used stainless and it is both harder to bend and drill, but stronger. Safe boating all!

Hi there, I need to replace mine too, somewhat different shape (Shabah 182 BR), look at Aluminum 36 x 5 Inch Boat Piano Hinge

may do with some rework/weld a flat bar onto it.....
