How to weld a prop inside another prop

In this tutorial I'll show you how to weld props inside another prop that has no hollow hitbox. Useful for cars for example.

Getting started

Before we begin, we need a spawn the desired prop. Then disable it's collisions with C + Right Click on the prop. Now enter the NoClip mode with V.

Positioning the prop

Move your prop to the desired place in the other prop.












Then hold Space to get up without moving the mouse too much, until you're outside the other prop's hitbox. Now freeze the prop.

Pausing the physics

Okay, now select the Weld Tool, which should also switch to the Tool Gun.












Now go to Utilities -> Server Settings and then set the Physics Timescale to 0.
















IMPORTANT:
Make sure that you FIRST select Weld Tool and THEN go to Server Settings, to keep it in the C menu!

Welding the prop

Now unfreeze carefully the prop and then switch to the Tool Gun which should have the Weld Tool now. Start the weld on this prop but don't finish the weld!












Now carefully increase the Physics Timescale up to 0.05 (0.01 if you have more patience) and then wait until the prop reaches the desired spot. Now finish the weld by "shooting" the other prop.

Conclusion

The prop should now be welded to the other prop at the desired spot.

Set the Physics Timeline to 1.00 (default), exit NoClip with V and you're done!

That's a neat trick that doesn't require any mods! However, if you're on a multiplayer server, you can use one of the following (if the server has the mod in question).

Fading Door Tool - Apply a fading door with keybind to the larger prop (Toggle is easier), get the weld tool, hit the larger prop and use the keybind to weld to it (or vice versa)!

Precision Tool - This one is a bit trickier. Make sure your Precision settings have 'Precision Move' added to the Undo list. Set the Push amount to something like 5, you want it to move far enough to access the hitbox of the other prop. Push the larger prop, start the weld on the smaller prop, press Z to undo the Precision Move, and weld the larger prop!

Hope this helps ^^
