Why you're using Jev wrong: four fixes from TypeSafe's docs

Most bad Jev results come from an unpinned alias, maths left to the model, vague questions and one threshold for every action. TypeSafe's docs give the fixes.

Do you need insulated tools to work on a hybrid or EV?

Yes, for the high-voltage system: isolate it and prove it dead first, then use IEC 60900 tools, because parts can hold voltage after isolation.

Do tapped holes need masking before anodising?

Workshop

Sadaf MasoodOct 28, 2026

Do tapped holes need masking before anodising?

Usually yes. A 6H tapped hole has no allowance for coating, and hard anodise can close it by 0.1 mm. Mask and conversion coat it, and say so on the drawing.

Stripped spark plug thread: can you fix it with the head on?

Usually, yes: drill, tap and fit an M14x1.25 coil insert with the valves closed and swarf kept out. Match the insert length to the plug's reach first.

Does welding 6061-T6 or 6082-T6 make it weaker?

Workshop

Sadaf MasoodOct 20, 2026

Does welding 6061-T6 or 6082-T6 make it weaker?

Yes. The metal beside the weld loses about 40% of its tensile strength and half its proof strength, and ageing won't restore it. Size to the welded figures.

How often does a digital torque adapter need calibrating?

Every 12 months or 5,000 cycles under ISO 6789, sooner after a drop. Check it between calibrations with a known weight on a measured bar.

6061 or 6082: which aluminium should the drawing call for?

Workshop

Uzair bin HaroonOct 19, 2026

6061 or 6082: which aluminium should the drawing call for?

For most machined parts either works: 6082-T6 meets 6061-T6's minimum strength. Write both; name one only for decorative anodise or a set spec.
