Trunk Board

Re: Trunk Board

My '59 is 30-3/8 +/- 1/16

Bill, if you could, would you post the dimensions of the cutout for the trunk lock. I believe like the '60 your '59 has a cutout there. From picture I have seem, it is off center with a shorter side on the left, so I need the dimension of the left, top and right side if you would be so kind.

Thanks,

Re: Trunk Board

I'm guessing that there is something wrong with the spare covers that are sold from the various vendors?

I purchased one for my 60 but used 5 ply 'marine' plywood to make one many years back.

Re: Trunk Board

To the best of my recollection both Corvette Central and Paragon sold a correct board up until a yr or two ago. It was five ply with each ply being uniformly around .075" for a total thickness of About .375" and the grain appeared as original ( maybe Yellow Pine). For some reason they both discontinued this item. I am told that there are some five ply boards out there now with three thick plys and two very thin plys to meet Judging Maunal requirements but not what one would expect to see in an OE board. Maybe using thick marine five ply and milling material from the top and bottom to attain OE overall thickness.

Re: Trunk Board

Paragon does sell a board. I have only see the picture on their web site, but It looks to be made from birch or some other fine grain wood. The pictures above and other pictures of original boards look to be made of yellow pine from the look of the grain.

Re: Trunk Board

That is the problem I ran into. The grains are not right. The problem is this modern plywoods that are 5 ply and 3/8" thick are for the most part a finish plywood. This is why it is finished in a finer grain. The original board is more of a "construction" grade. Which explains the pine veneer. In the construction business years ago we could buy this every day. GM evidenty did. It would have been classified as an ( A) or (BC) grade. I have my plywood suppliers looking for this, or perhaps an acceptable Veneer.

If anyone has the Paragon aftermarket I would be interested to see the graining and to know if the thickness is right. I have and original to compare it too.

Is there an acceptable "off the shelf" Label Glue for the board?

Appreciate all this discussion. Maybe together we can solve this.

Don:

Let's locate the cuts relative to a diameter and the center of the board on the top surface.

Draw a line along a diameter of the board kinda perpendicular to the grain. (The grain on my board runs left to right, not up and down.)

Draw a line perpendicular to the diameter 12-1/2 from the board center. This is the top cut.

Draw a line parallel to the diameter 4-1/8 to the left of the diameter. This is the left cut.

Draw a line parallel to the diameter 1/2 to the left of the diameter. This is the right cut.

Check to make sure the left cut is about 1-3/8, the right cut is about 2, and the top cut is about 3-5/8.

My original board has rounded corners, not square cut, with a radius of about 1/4.

Bill,

Excellent, makes it easy to make the correct cut. And yes, I noticed from pictures of other original board that the corners of the cutout are rounded. I assume all edges have been eased a little around the outer edge, etc.

Does anyone know if there was a protective coating or just stained board and not varnish or there coating.

Re: Trunk Board

I'm not sure if the board in my 62 is correct or not. It is 30 3/8" diameter and the thickness is 5 ply and about 3/8". The plys are thin on outer-inner-outer plys (1,3,5) and thicker plys on (2,4) sandwiched.

Re: Trunk Board

Here are pictures of my original? board. You can easily see the ply thickness's!

Re: Trunk Board

My board looks just like yours Chris. Plys are identical.

Re: Trunk Board

I have several original boerds from various cars 57/62 and none are of the quality sufficient for a judged car. Realizing that I would need 2/57's - 2/58' s and 2/62's I began chasing the proper wood about a year ago. After hours of calls to dozens of people in the last year , I am no closer to finding the proper carolina yellow pine 5 ply .375 wood or even .075 carolina yellow pine veneer to fabricate, I have even offered to purchase a special setup and buy a mil run to no avail...... the wood is the key as I can program and pop out 15/20 per hour --------If anybody here has an idea on a wood source, spend some time here. Again from my previous post --- Face A grade back face could be B or C grade.------------ The CC and Paragon boards offered at this time are not as OE(3ply). Saw a very nice OE board at Kiss last winter at 600 bucks. Hard to swallow when with the right wood a guy ought to be able to build and sell for 150 or less.------------Any importers here? Chinese Yellow Pine might work!!!!!!!!!! ----------------Regards/Joel Miller

No evidence of a hard finish.

Re: Trunk Board

I was able to fine Carolina yellow pine veneer in 4' x 8' sheets (10 ML and 22 ML), picture attached. If you can find decent 3/8" plywood with 5 plys then used this veneer on top and bottom, it should look right. The 10 ML would be almost impreceptible on the edge. However, it isn't cheap, $75 for a sheet of the 10 ML and $94 for a sheet of the 22 ML. Here's a link to the website.

Re: Trunk Board

The grain looks like my original board.

have bought froom Oakwood. Good company. Owner helped me and even thru in some free veneer that was damaged.
