Country Wood Turner Posted December 2, 2018 Report Share Posted December 2, 2018 I have to make a 9 ft flag pole out of 1.5 in maple. The pole has to fit in a carrying bag and my customer wants it to break down into 3 pieces that screw together. I have tried a few methods to connect the pole without success. Every time any pressure is brought to bear on a joint, the dowel cracks. Any suggestions on how to do this? Quote Link to comment Share on other sites More sharing options...
wdwerker Posted December 2, 2018 Report Share Posted December 2, 2018 Get some copper, brass or aluminum tubing the diameter you like. Offset the screw joint about 4" into the tubing. So a 8" section of tubing should reinforce the joint nicely. A little epoxy and maybe a countersunk screw or 2 will stabilize the fixed end. I imagine the dowel screw will need to be accurately centered. Quote Link to comment Share on other sites More sharing options...
krtwood Posted December 2, 2018 Report Share Posted December 2, 2018 Maybe a large tee nut? You can get them for at least up to 5/8" thread. Drill holes for screws in the flange. https://www.mcmaster.com/90596a033 Tubing around the joint wouldn't hurt either. Quote Link to comment Share on other sites More sharing options...
JohnG Posted December 2, 2018 Report Share Posted December 2, 2018 Have you looked into hardware for pool cues? They are smaller diameter at the connection point but still very solid. Make sure the faces mate perfectly or else any connection method will be more likely to fail. 1 Quote Link to comment Share on other sites More sharing options...
Isaac Posted December 3, 2018 Report Share Posted December 3, 2018 https://www.amazon.com/Screw-Joint-Diameter-Poles-Brass/dp/B004EPJR10 Googling around, I was able to find those for up to 1 3/8 " diameter easily, but couldn't locate a 1 1/2". I've used these on cub scouts poles and they work well, so if you can get them to agree to 1 3/8 instead of 1 1/2, you should be golden. 1 Quote Link to comment Share on other sites More sharing options...
Country Wood Turner Posted December 11, 2018 Author Report Share Posted December 11, 2018 Thank you all for the suggestions. I found a solution by using the Beall Wood Threader. I made the threads on the male side easily and they look great. The taping of the threaded hole on the female side was another story. I was tapping g into end grain which, by Beall's own admission does not work very well. What I found however was that while the tapping did not produce crisp threads, it did produce usable threads. Seeing that they will be invisible in most cases I decided to use them. I also poured wood stabilizer into the hole and allowed it to coat the threads. After about 10 minutes I poured out the excess stabilizer and allowed it to dry. This gave me a very acceptable join. 2 Quote Link to comment Share on other sites More sharing options...
