The wizard works a lot with parts printed on a 3D printer. Various methods are used to connect parts, including metal fasteners. To install metal nuts in the holes they are heated with a soldering iron with a special nozzle. This can be seen in the video.

This is not a bad way, but when installing with a soldering iron, the nut may not be smooth. To avoid skewing, the master made his own thermal press.


Tools and materials:

-Bearing 608;
-Fasteners;

-Springs;
-Lubrication;
-Screwdriver;

Step One: 3D Printing
First, the master developed the details in a special program.










Then he printed the details on a 3D printer. When printing, the master used the PETG thread, but the parts from ABS will be tougher. For printing, the master set the following parameters: layer height 0.15 mm, filling 20%. Printing pens requires support.

Step Two: Install Bearings and Guide
First, the master installs the bearings.



Then it installs the nuts and fastens the guide rail. The guide master lubricates.





Step Three: Protect
Sets a protective screen. Inside the shield will be a soldering iron.







Step Four: Install Threaded Bushings
Initially, the master planned to install nuts, but then he decided to install special thermal inserts.







Thermal inserts are threaded bushings with a corrugated outer surface.






Step Five: Bracket
Bracket master made in two versions. A suitable bracket is installed depending on the springs.





Step Six: Build
The master screws the stand to the base. Screws the bracket to the stand.







Installs the bracket and secures the soldering iron. The wire is secured with plastic ties.






Sets the lever part.





Sets the second section of the lever.





Sets the last section and handle.









Now it remains to install the threaded rod. He will play the role of a limiter. If necessary, it can be twisted or unscrewed the stroke of the press will be limited to the rod. The master installs and locks the washer on top of the shaft for easy adjustment.






And at the end, some advice from the master: use conical thermal inserts, not cylindrical ones.It is very difficult to install cylindrical inserts straight.

The argument is pointless. You can only verify by experience
I agree, the argument is pointless with you, I fused the bushings with a soldering iron, I know what I'm talking about.
And at the end, some advice from the master: use conical thermal inserts, not cylindrical ones. It is very difficult to install cylindrical inserts straight
And that’s what the master says, fusing the bushings with a press and a special sting!
P.S. And thanks for the photo PSU!

The argument is pointless. You can only verify by experience. In one of the videos, the test is a soldering iron with a cone, and the deviations are minimal. If you use a couple of times a year, and the machine makes no sense, an ordinary soldering iron. And if it were precisely the tip, then he would have written about it.
He writes: Soldering iron: Hakko 888
This iron is discontinued, but the very popular replacement 888D used the same iron tip (PN: FX8801-02)
We are looking for FX8801-02. And we find.

That's all, he gives no more information on soldering irons, tips, etc. There are true links to the finished press there.
But he writes: As you can see from the video above, you do not need to click to add thermal inserts to your project, but using the press, you maintain better vertical alignment, better control over depth and speed.
Those. the emphasis is on the press, not the sting. But which sting will be better, this can already be experimentally determined. And he does not finish the sting, but most likely buys.

Insert the nail, center and the sleeve will press smoothly
You are mistaken, the nail (cone) does not fix the position of the sleeve and its lower part can "go" in any direction, given that the top layer of plastic will be softer than the inside.

Firstly, he does not talk about the completion of the sting. Secondly, the diameter of the bushings can be different, and then for each size, you need your own sting. Thirdly, by installing such a tip on a soldering iron, you will still get mowing. Homemade about the press, not about the sting. Insert the nail, center and the sleeve will fit evenly. It is clear that with a convenient sting it is easier, but the point is not in it.

But I think this is not a matter of principle
You again do not delve into the essence of homemade work! It is possible to melt bushings into plastic bios and a soldering iron with a conical sting! And for a strictly vertical landing, the author made a press, and the sting has a thin guide for the sleeve and a horizontal plane, and this is important!

The author does not write about the completion of the sting. But it seems to me this is not a matter of principle. On many (modern) soldering irons, the tips are replaceable. Replacing literally 10 seconds. Choose the diameter of the sleeve, not a problem.

On the press, yes, the sting is different
That is the question!

And you watch the video, then, where is one soldering iron. There is a cone. In the press, yes, the sting is different. I think it makes no difference, the main thing is to heat, and the tip intermeddle inside the insert.

-on the cone sharpened
Most photos clearly show that this is not a cone! nea

Not a word about the completion of the soldering iron tip, but a pity.
