Repairing a Stripped Wooden Screw Hole
by Lorne Goldman

Morgans are partially made with wood. This is how ALL were once made. It is an excellent material to mate withthe famous classic Morgan flexing chassis that is so much part of the personalityof the ca. Wood also has some properties that make it ideal for a car. However, this is not  an article to explain the merits of  the use of wood in automobiles, it is to address one of the most common problems encountered in the use of this product.

I often get approached with  questions on how to repair a stripped wooden hole. And this time I decided to write down my most common fixes for posterity. :)


Firstly, I must say I dislike the use of epoxies, glue or resins to make a wood repair. Wood reacts to moisture, aging, stress and flexing differently from other materials, so why combine materials with different characteristics if it is at all unnecessary? And I am loathe to use a larger screw if I can avoid it. I favor quick and easy non-invasive repair methods that can be performed even when mogging about. I classify these fixes in two types; those where the fittings are NOT subject to lots of stress and those points that are going to be subject to a greater force.

Low Stress.  If a small screw and hole are involved, simply remove the screw, stuff a toothpick (or a bigger wood chip if the hole requires it) in the hole. It need only take up a part of the old hole space and no glue or anything is needed. Breaking off the excess length and replace the screw. You see all wood screws hold fast by compressing the wood they fasten into. A little toothpick is often all you need to force the compression to work again. 

High Stress. For larger, stress spots, where larger screws have been used and eventually failed, I opt for a method that spreads the stress over a much larger area.  I use T-nuts made for wooden applications. Find one that will fit the original hole and then switch to a metal screw and washer that suits the threades of the T-Nut. There is no need to piece a larger hole or prep the area. Run the new screw into the old hole and thread it a bit on the T-nut. Now, as you tighten the screw, the nut will piece and secure itself on the other say of the subject wood. If you wish to make the T-nut side flush, intent them slightly.
