Threaded inserts are great for making bolted connections when securing parts together.
Adding metal threads to your parts will significantly increase the durability.
You can also loosen the connection and take it apart without wearing out the threads.
The knurling on the outside of these brass inserts are design for heat setting plastic.
A tip specifically designed for installing inserts works better than regular soldering tips.
These are compatible with irons that use internal ceramic heaters like Hakko’s and Weller’s. The longer shank reaches deeper into parts and tight corners without touching plastic.
How It Works
The build uses 2020 aluminum and a roller carriage – It’s got ball bearings and wheels to go up and down the piece of 2020. It’s counter weighted so it’s effortless to press down and lift. There’s a pulley and idler at the top for paracord to loop around a ball bearing.
The soldering iron is clamped to an arm and bolted to the roller carriage.
A T-Nut acts as an end stop and prevents the tip of the iron from hitting the platform.
The platform itself is a piece of wood with the 2020 secured to a 3d printed bracket.
This makes heat sets so much more precise and gives perfectly straight results every time.
So if you’re making lots of parts and need to streamline your production, this might work for you.
