Tools
Strongback Forge
Damage-control strongbacks sized to the pipe actually in front of you — including bends, weld beads and full sleeves.
- Straight pipe, bends (outside or inside of the bend), and full 360° sleeves
- Weld-bead relief for butt and seam welds
- Band-strap channels, edge ramps, gasket pockets and closed-loop end seals
- Live 3D preview — runs entirely in your browser, nothing is uploaded
Blank Forge
Circular blanks and blind plates. Pick an ASME B16.5 flange or type measured numbers, and it builds the plate and its bolt pattern.
- ASME B16.5 Class 150 / 300 / 600 presets, or fully custom
- Bolt circle, hole count, hole size and clearance; pattern rotation
- Optional centre hole, edge and bolt-hole chamfers, index notch
- Paddle handle with a tag hole, so the blank is visible and accountable
FME Cover Forge
Caps for open pipe ends — press-fit or threaded — so nothing gets into a system while it is opened up.
- Press fit with crush ribs that grip a range of real pipe ODs
- Threaded: NPT (with the 1:16 taper), NPS straight, and UN machine threads
- Lead-in funnel, external grip flutes, engraved tag number
- Lanyard ear — an untethered cover is future foreign material
Knob Forge
Replacement knobs and control handles for any shaft. Round, teardrop selector, oval or bar in plan.
- Plan shapes: round, teardrop pointer, oval, bar / lever
- Bores: round, D-shaft, double-D, square, hex, splined, keyway, threaded
- Styles: plain, knurled, fluted, lobed, wing, hex outside
- Blind or through bore; flat, domed or dished top; taper and chamfers
- Indicator pointer across the top, optionally carried down the side
Adapter Forge
Two-sided hose and pipe adapters — pick a thread or a barb for each end independently, and it builds the fitting between them.
- Each end independent: NPT male/female, UN male/female, hose barb, plain tube
- Real NPT taper on both external and internal threads
- Hex wrench flats, through bore, per-end lengths and barb counts
- Burst estimate on the thinnest section — and a blunt note on how these fail
Handwheel Forge
Spoked valve handwheels with the valve name engraved round the rim, the way etched plastisol reads.
- 2–10 spokes, dished or flat, rounded rim section
- Square broach, round, hex, keyed or D-flat stem fitting
- Hex recess for the stem nut
- Valve name wrapped round the rim — e.g. "PW-100 POTABLE ISOLATION"

Specific caution on printed parts
Anything produced by the tools on this site is an experimental or training aid. A 3D-printed part is not an approved repair component. Printed plastics have limited strength and temperature capability, and material behaviour varies with printer, settings, and orientation.
Do not install a printed part on any pressurised, energised, hot, or safety-related system. Have any such application reviewed and approved through the appropriate engineering authority first.
