Sipo Alternatives
« on: September 11, 2020, 11:39 AM »
I want to make my down dominos for an outdoor project made out of redwood or cedar.  I was originally thinking of just using redwood or cedar as the tenons but perhaps they wouldn't be strong enough?  Your thoughts and suggestions?

If the tenons are being used to just hold boards together then strength isn't really an issue. If however they will be used for structural purposes then it could be an issue. The application will dictate the outcome.

For instance, Janka hardness on Sipo is 1180 while on cedar it's 320 and on redwood it's 420.

It will be a garden arbor with climbing plants on it.  I don't do a whole lot of outdoor projects so I'm hesitant to spend the money on sipo.

And to think I got some 6 mm Sipos just to try and inlay normal 4 mm into them.
Hobbyist just trying to have fun and not let my OCD ruin it for me.

In that application I wouldn't worry about it. If I understand you correctly, you're talking about 30#-40# of plant matter hanging off of it as opposed to 200#-300# of human matter hanging off of it.

In the case of a table or chair leg splayed out at a 45ยบ angle there are issues, you have a completely different situation. We'd be delighted to see the finished product.  [big grin]

So, savsuds, that means you have a bunch of leftover Sipos to donate to jusssi for his project, right?  [laughing]
