Superglue "wicking" into threaded holes in LC board

Postby davistroy » Thu Jan 31, 2013 1:12 pm

Hi, I purchased a Prusa i3 lasercut frame and it mentions tapping screws directly into the material after wicking in superglue. Before I go and screw something up (no pun intended), is there a preferred process for doing the superglue wicking?

From: http://shop.seemecnc.com/Prusa-i3-LC-Pa ... -i3LCP.htm

"The melamine will take a thread itself fairly nice, if you tap it, then use thin super glue "wicked" into the threads to strenghten them."

Davis, I do this all the time on other projects and it is simple. First, tap the hole carefully so as not to cross thread. Then, use the thin type of super glue. It is usually called CA glue at the hobby shop and comes in different viscosities, or thicknesses. The thin is like water. I use a small 2cc plastic syringe with a steel blunt tip applicator needle - you can get these at most hobby stores too. Simple inject or drop a little super glue onto the threads. The melamine will wick it in like water and then when it cures, it will be nice and hard.

Cheers,
Michael

I believe you owe this post some pictures of your other projects, no? :D I just like to see your stuff.

Are you happy with the Grizzly stuff? I almost went that route instead of the 3d printer a few years ago.

foshon, one thing I've learned is to never make recommendations for complex things like milling machines, etc. Am I happy? Absolutely? Did I completely rebuild the machine to add CNC? Absolutely, that was my intent from day 1. Would I recommend them to folks that know how to problem solve, seek information and have a general desire to learn as they go? Yes. But I would not recommend them to someone who needs a turnkey machine out of the box. These cost $1000s more and even then require some basic knowledge. Sounds a little familiar to what's going on here!
