Yes stainless steel is stronger than aluminum rivets. But aluminum is what's used in most aircraft, so they are plenty strong. But you cannot use aluminum rivets with anything--but aluminum as you will get galvanic corrosion through electrolysis. The exception is if your steel has been galvanized or sometimes heavily anodized you can also use insulators from plastic to nylon. There are Apex rivets which uses a steel stem and aluminum heads the stems have been galvanized. They are a stronger alternative for use with aluminum sheet and or tubing.
Thanks for the video. I'm making rails to support a ezup tent and wanted to travel with 5' sections of pipe. I think I'll use your glue method on one end of the spline and none on the other. Maybe put a screw coupler as well to make sure the two pieces don't come apart until I want them to. Your video helped a lot. My biggest issue now is trying to find that inner pipe that fits well enough on the inside of the 1" conduit that I'm planning on using. 1/4" leaves too large of a gap.
0one the glued hot dogging inner tube on my 10 by 8 foot Bimini frame to extend it original size. The glue I used is PL Premium polyurethane.I mixed in a little sawdust to set it quicker. Frame has survived high winds. The Bimini tubing ends I just glued 6 of them with PL and no sawdust. We had a severe wind storm, and one of the inner bows pulled out from the ends. With the glue they also will no longer hold rain water. Other ends I have drilled through the tubing and ran bolts or sheet metal screws.
Any tubing with a wall thickness of .058 well except the next size smaller with a few thousandths of an inch gap example 5/8 tubing with a .058 wall well except a half inch outer diameter tube, since the 5/8 inner diameter is .509 this means it has 9 thousands of an inch clearance between the two tubes.
I know you have to be careful putting unlike metals together. Is it kosher to use the mild steel I have as a spline with my stainless tubing, or is there an important reason to stick with stainless?
It's best to use stainless steel with stainless steel, but you could also use aluminum if you cant find the right size spline. The aluminum would have a reaction, but it makes the joint stronger as they bond together. I would not use mild steel with the stainless steel as mild steel rusts very easily.
A drill bit that fits into the hole left by the mandrel, it should be only large enough to bit into the inside circumference of the rolled mushroom head of the rivet.
Hi Ed, Using a spline does not weaken the bow or tubing. In fact Jeff (our sail designer at Sailrite) actually says in a way that it strengthens the tubing, if the spline is securely fastened to the tubing.
Although the video is good, the author's definition of a spline is not what I learned while working with machinery. Wikipedia displays has a good definition: en.wikipedia.org/wiki/Spline_(mechanical) I would say the video portrays more of a bushing or sleeve being used to join the tubes.
Here is a link to 1 foot sections of tubing that you can use for splines: www.sailrite.com/All-Hardware/Boat-Hardware/Frames-and-Tubing/Length/1-FT/type/Products?order=custitem_popularity
Why did you call it a spline, it's not a spline, also why use tape on one end and not the other, the tube will slop about if it's a loose fit which will loosen the rivet. Why show an aluminium rivet then say it's not recommended?
True, but you will notice that the vice is not locked down for the drill press. Had we locked it down we would have protected the tubing from the vice's teeth with fabric or leather.
@@SailriteDIY Locked down or not, you have the metal of the jaws of the vice compressing against the tubing, which negates what the leather is to do, protect the leather from the jaws.
@@SailriteDIY Would this also work for thick wall pipe and/or structural tubing for building framework and such? Though I'd imagine structural blind rivets would have to be used for superior strength under heavy shock loads.
A pilot hole is a "HOLE". A punch mark is just that...a punch mark, a center punch mark, a dimple, a place to help locate a drill bit so that a pilot hole can be drilled after center punching. This narrator is clearly just a talking head that is regurgitating data from a script.
@@SailriteDIY I watched the video and it was pretty clear what you were instructing people to do. Not sure why some folks look for any reason whatsoever to make a negative comment, otherwise they say nothing at all.
@@markthompson8656 My husband made the original post. I rarely make comments online. I find the interaction always more negative than positive. Even though I was confused at first because I never posted. Thank you for letting me know what constructive criticism means.
