How we built the salvaged acacia arbor from an old barn

Last year, after the acacia, we received a message from a reader telling how he salvaged acacia wood from an old barn and used it to build a gazebo. He was impressed by the strength and hardness of the wood. The way he told his story, his enthusiasm and his desire to share his experience with someone who has the same passion for wood impressed me and that's how we got to know each other (unfortunately only virtually). Although it may seem like a simple story about building a gazebo using old wood, I think it is more than that. It is a story about passion, about reclaimed wood, about memories transferred to a new gazebo, about dreams, plans and wishes, and last but not least, about family. It gives me pleasure to tell you this story, occasionally in the words of the 'little one'.

This is Claudiu Gârceavă, who makes a good living by making furniture out of melamine chipboard, but dreams of a workshop where he can work with solid wood. Last fall, last year, he demolished an old shed - a barn or porumbar, as we call it in the South - and decided to salvage the old acacia posts. The porumbar was built in 1949 to hold not only corn, but also firewood and the cane used to make wine barrels.

Some of the wood had been in the ground, the marks left by damp, but especially by insects, being very visible after the bark was removed. Yet the wood was just as hard and strong.

Each acacia pole was carefully cleaned with a hatchet and a nail file, the old nails were removed and it was prepared for future construction.

"At the gazebo we used recovered wood The horizontal bars linking the poles at the top, the horizontal T-shaped beams between each pair of poles at the bottom and the center pole. The gazebo has a diameter of 5 m in the area of the pillars and 6.5 m in the area of the roof (seen from above), and is 8-sided (octagonal)".

Because the salvaged wood was not enough, he had to buy another 4 m of timber, which he circular cut and made into rafters. After he made the structure, he sprayed it all with a sealing oil, left it in the sun for 2 days to dry, then applied a rosewood-colored varnish. In the meantime, winter came, so he had to stop. This gave the wood time to 'settle' over the winter.

"This year, as soon as the heat turned up, I started again. I put the shingles on the roof on all 8 sides, fastened in holdouts, 900 holdouts in 3 days. I then covered it with thin bituminous membrane, overlapped at the ends 10 cm and fastened from place to place in long staples. In a day it was ready, but the sun was baking me, by the end of the day we were both black, me and the membrane."

The next few days the weather was nice, so he could lay the bituminous shingle in peace. It took 4 days and ... 1750 nails. On the edges he put all the shingles, cut into a drop shape, and glued it down with mastic.

With the roof ready he allowed it to rest for 2 weeks, then moved on to the bottom of the gazebo. Still from 280 x 50 mm and 4 m long planks, he made the horizontal poles and laid them over the planking. Everything had to be prepared for all the fastening to the acacia poles, after which holdouts were used. The acacia turned out to be so hard that nothing would get through, and smoke came out of the drill when drilling.

The pole was wrapped in string to "finish" the rather rough surface of the acacia. He didn't want to straighten it so as not to thin it by even 1 mm. "For one and a half meter of pole I needed 50 (fifty) meters of string. 🙂 I couldn't believe it!"

Also on the center pillar, 5 feet off the ground, he put four anchor sites for 250 pounds each for hammocks. "After lunch, you can relax in a hammock when it's a torrential downpour of bubbling rapids outside."

Inside he put 2 benches he bought, but adapted for the gazebo and a 3rd one, made of an old plank eaten by curries. "I hollowed it out until I found good wood, let it dry, then I put some varnish on it and fixed it to 2 acacia logs that look like ceramic. It is a very comfortable bench."

I was telling you at the beginning about Caludiu's enthusiasm. I thought long and hard about how I could say what was to come, but no way could capture Claudiu's excitement, joy of accomplishment and love of wood. So I'll let him tell you again.

"What I wanted to tell you is that every nail, every shingle, and every wood cutting, chertizing and finishing was done by me and me alone. It was and will remain my first solid wood project. Sometimes I feel I love wood more than people. You know, I'm a pastry confectioner by trade (for real 🙂 🙂 I've been making melamine-wood furniture since 2000, before that I made pastries. My dream is to set up a workshop where I work with solid wood, and I'm striving to fulfill my dream, together with my family. I have a daughter, a pupil at Tonita, and a 5 year old son, who scares me with his tenacity and patience. And of course my wife, who understands and loves us all."

the little craftsman

As well as the satisfaction of having done everything himself, Claudiu is also proud of the fact that he did it all by hand. As tools he used a foxtail saw (the longest), a drill, a flex, a hammer, an axe, a hatchet, a vise and a scissors. "The gazebo is 8-sided - octagonal - and the metal piece at the top, where the rafters and the center pole attach, I made from a piece of 3mm sheet metal. I drew the shape, cut it out with the thin diamond disk flex, drilled holes in it, and then bent it by hand in vice and hammer, on the fine grooves I made with the flex (the sheet was quite thick). This piece basically supports the roof and connects the rafters to the central acacia pillar, and is fastened to it with a hex-headed holdout screw, 20 cm long and 1 cm thick. You don't know what satisfaction it gave me when I climbed it and stood on the top".

Now the gazebo is ready, so everyone can enjoy it in peace. Maybe except Claudiu. Not that he wouldn't enjoy it, but I don't think he does it in peace because he already has a lot of other projects on his mind and he's itching to get started. 🙂

  • I read this article with great excitement, especially since the "culprit" of this project is literally my brother. I enjoyed every word you and he said. I'm glad that there are so many people who appreciate Clau's stubbornness and at the same time simplicity and I wish that in the future he will be at least as skilled as he is now.

    While reading this article, I had the feeling that I was sitting on the sun lounger under the gazebo.
    Congratulations on the article Mrs Mihaela, and congratulations to you too Claule... just know that no matter what the situation, I'm always relaxed because I'm more than convinced you're dealing with any problem. 🙂

    • Thanks for the appreciation, but I think congratulations are in order for Claudiu. I was just... the scribe. 🙂
      All the best!

      • Sarumana madam, thank you once again for your time and maybe we can meet for a chat or even a walk to the site to show you in detail how we did the joints, and little details that make the gazebo special!

      • I would like to add that it is an eight-sided octagonal gazebo, and the piece of metal at the top on which the trusses and the central post are attached, I made it from a piece of 3mm sheet metal on which I drew the shape, cut it with a thin diamond disk flex, drilled it and then bent it manually in the vice and with a hammer on shallow trenches that I drew with the flex (to facilitate bending of the rather thick sheet metal).
        This piece basically supports and connects all the rafters and is also fixed to the central salcam post with a 20cm long and 1cm thick hexagonal head screw.
        I wrapped the pole in twine to "finish" the rather rough surface of the sausage.I did not want to finish the middle pole so as not to thin it by 1 mm.

      • Congratulations on the gazebo, your hard work and ingenuity. It shows very well the good ideas in desging that you have applied. Congratulations also to the lady for the well written article and especially for the pictures.

        • Thank you very much, I'll try to post in detail each stage with pictures with everything, from the bedding put in the ground and measuring the diameter, center, etc. to the last nail at the top of the shingle!
          Today he received another wagon wheel mounted vertically between the eaves and the pulley, it's the wheel that unchimiu had from his grandfather's wagon, it's made of ash and it's 110 years old, it's a wheel of the soul!
          But I'll keep you posted on everything else!

          • Hello. I am asking for your help given my experience in recovering old wooden posts. I have seen that you have recovered acacia poles that were eaten by decay. I received an oak pole from a neighbour, pole that has been on the ground for several years. I am supposed to use it as a support pole for an electric cable to power the house. It has more rotted and decayed portions on the part that has been sitting on (in) the ground). I have cleaned this part (I still have work to do) and then I want to treat it with Sadolin Anticarii (twice) after which I don't know how to prepare it to be put in the ground to last as long as possible. Basically how to treat the part that will stay in the ground so that it doesn't rot and break (I've had this happen with the first fir pole) and how to treat the rest of the pole that will be exposed to sun, rain, etc. Again, the pole is made of oak but has a damaged surface but I can see that the "heart" of the trunk is ok and strong even if it still has holes and cracks going inwards. Thanks to anyone who can give me suggestions.

        • As far as I know, the wood that will be put into the ground is burned on the surface and then tarred, if you put the wood into the pit of the post, say 60cm, the tar must be about 10 cm above ground level.
          A very important thing to do is to put crushed (broken) gravel not too bad at the bottom of the hole and then place the post in the hole, so the water from the ground will not "climb" on the post.
          I don't know how the oak behaves to peeling and decay but what I can say is that the salcam wood has decayed in 70 years only at the lower layer because the inner layer is very hard and there is no way to enter, more precisely from 130...140mm diameter of the pole in the ground that was not treated with anything there is 110mm of raw salcam (steel) left after peeling and cleaning, I hammered into it and it doesn't even leave traces!
