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.
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.
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.
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.
@@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.
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
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.
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.
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?
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.

With self screw is stronger and better
I found this to be an alternative for a compact diy telescoping tent or tarp pole. The sections could be easily transportable.
how to rivet 1.5 inch round steel pipe to a flat steel plate surface, both about 2mm thick ?
Is it possible to join two tubes with a kind of spring with a bump on the second part so the two pieces can be detachable?
Do you mean a Spring Ball? www.sailrite.com/Spring-Ball-Stainless-Steel
Very professional looking work !

If I want to replace rivets on my handrails on the bow of my boat what drill size would I use to drill out the old rivet?
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.
@@SailriteDIY Thank you.
Greate, thanks Graig.
What if you used galvanized pipe

Buy that man a cordless rivet gun for Christmas. Sheesh.
No need for the 7/8 piece: slice lengthwise a 1" piece, (2 cuts with a cutting disc on the grinder)compress it and insert it.
Jose Peixoto wow thanks
What does a spline do to the strength of the overall member? Stronger, weakens, or no change?
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.
what system or mechanism is that when one smaller sized tube inserted to the other bigger sized tube?
telescoping
Thanks for posting this information
Thanks for these videos. I will buy from you to thank you for them.

How many rivets do you need per splice?
You only need one on each side. So two per splice.
@@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.
@@jonathanchark5291 We have not tested it for that type of application. Sorry, we just don't know.
Where do you get the splines from...what are they called....what do I ask for?

Thanks for your comments and your definition of a spline from wikipedia. You have a good point.
Lol, well you know! Thier just good bits!
It's a SPLICE, not a spline or a spine.
Using leather to protect the tubing yet you are using a vice jaws which is not protecting the tubing. At 1:17

Galvanic corrosion will destroy the aluminum rivet in outdoor application
Yes, that is why we recommend stainless steel rivets: www.sailrite.com/Rivet-Grooved-Blind-Stainless-Steel
frank, have you even looked at stainless aluminum galvanic corrosion rates?
Yeah, in 50 years you may need to replace it.
Pretty much how not to do it.
Post your video showing how..
Cool
Glad you liked it!
SPLICE NOT SPLINE! ARGH!
Spline = secure (a part) by means of a spline.
toobing :D
Nice commentary accent
You could have lined up the two rivets better. Get a sharpie next time.
Good idea!
Nice 😜💪🏽
