Configure a soft-face machinist's hammer — or a hand tapper with no handle at all — and get the detail prints out the other side. One HTML file, runs offline in any browser, nothing to install. Licensed to one person, in their own shop: make as many as you like and sell every one of them.
One file. Download it, double-click it, and it runs. No install, no account, no internet, nothing sent anywhere. Keep it wherever you keep documents and back it up the same way. It works offline forever, and the handbook travels inside it.
What comes out. ANSI B sheets in third-angle projection with ASME Y14.5 annotation — assembly, handle, housing, tip insert, and the sheets the configuration earns: the brass cap that closes a gun-drilled butt, the monogram, the O-ring on a shot-tube head, the spanner wrench cut to your own insert. Layered R12 DXF, true-size SVG with the engraving on its own layer, and a STEP assembly — real named components, each part in its own material color, threads on their basic envelopes with the designation in the component name.
Why the sheets agree with each other. One profile drives every view, the section, the isometric, the mass, the balance and the STEP export. Every dimension on the paper is the parameter you set, formatted — never a number measured off a picture. Change the barrel diameter and the whole set moves together, because there is only one thing to move.
What you can build. Five housing styles — cylindrical, hex, waisted, square with turned ends, and a shot-tube dead blow. Four grip forms from a plain cylinder to a full-hand fat grip, knurled or not, gun-drilled for light weight or solid. Faces from 3/8 to 1-3/4 in brass, copper, steel, aluminum, acetal, nylon or urethane, flat or crowned, and a different material on each end if you want one. Initials engraved on the housing in four letterforms, with the sheet telling you what will cut them.
It tells you when something will not work. A face that would overhang the bore is not offered. A grip too fat for the housing stops the slider rather than drawing a stepped joint. An engraving that would reach the handle bore is trimmed to the largest size that fits, and it says so. Knurl a housing and ask for a laser-marked monogram and it stops you, because a laser cannot mark a knurled surface.
A drawing is a proposal, not an inspection. The bench is internally consistent, which is most of what goes wrong on a hand-drafted print — but the datum scheme, the tolerance block and the thread class are template decisions, and reviewing the output is yours. Check it before you cut metal.
What this one covers
Licensed to one person. Install it on as many machines as you personally use — it follows you, not a computer.
It does not cover a company. Using the bench on behalf of a business with more than one person in it, or issuing its drawings as a company's controlled or released documentation, is the product license.
What every license grants
Produce unlimited drawings, DXF, SVG and STEP files from the bench, and make and sell the parts you draw — no royalty, no reporting, no cap on quantity. What you make with a tool is yours; that is what tools are for.
Give a drawing to a machine shop, a laser house or a plating house so they can make your part.
Keep using the version you bought for as long as you like. There is no subscription and nothing expires. Every update within Release 1 is free, and a future Release 2 would be a separate purchase — Release 1 is not taken away from you when it arrives.
What no license grants: sharing, reselling, sub-licensing or publishing the bench itself, putting it on a network or a website where others can reach it, or removing the release and authorship markings from the file.
The license, in one line. Yours to keep, and yours to sell the parts you make with it. The one thing it does not allow is passing the file itself on.
The same file, licensed for a company putting a hammer into its own catalogue: the right to issue the drawings as your company's released documentation, an invoice in the company's name, and up to five people at one named company.
Everything in the shop license, and the file is identical — nothing is withheld from the cheaper one. What differs is what you are allowed to do with the drawings that come out of it.
Released documentation. Put the sheets into a controlled drawing register, a supplier package, a customer submittal, a quality record or an instruction manual, and manufacture the parts as a product line under your own brand, in any quantity.
Five people at one named company, and an invoice in the company's name with whatever the bookkeeping needs on it. Ask and we will send one; purchase orders are fine.
What it does not do. It does not make your drawings correct for your job. The handbook says which decisions have been made for you, one family of parts at a time, and the engineer's signature on the print means what it has always meant.
Growing out of it. Past five users the site license is the difference in price, not a fresh purchase.
What this one covers
One named company is the licensee, and up to five people at that company may use the bench. Name the company when you buy; we will invoice in its name with whatever the bookkeeping needs on it — ask and we will send one.
Those five may issue the drawings as the company's released documentation — a controlled drawing register, a supplier package, a customer submittal, a quality record, an instruction manual — and the company may manufacture and sell the parts as a product line, in any quantity, under its own brand.
The bench itself still may not be shared beyond those five people, or put anywhere someone outside them can reach it.
If the company passes five users, the site license is the difference in price and not a fresh purchase. Write to us.

Two pattern makers for people who cut what they draw. Both run from a single HTML file in any browser — no install, no account, no internet after the download — and both export true-size SVG for a pen plotter, laser or router, plus a CSV of every point.
They are not two versions of one idea. They solve different geometry, and the curves look different because of it.
Mechanism Pattern Studio solves linkages. Seven of them — four-bar, drag link, slider-crank, five-bar pinned and sliding, two cranks on a telescoping bar, cam and follower — pinned, driven, and solved properly at every step, with a pen fixed anywhere on the moving parts and a turntable rotating under the paper. Bars swing and reverse, so the curves come out with cusps, loops and flat runs that no rolling circle produces. It tells you immediately when the lengths you have chosen cannot reach.
Trochoid Track Generator rolls. A planet on a track, with real tooth counts, so the figures close instead of drifting. The track can be one circle for the classic spirograph or up to six for racetracks, ovals and rounded polygons; the planet can be shaped rather than round, which is the quickest route to a figure no spirograph wheel could make. Roll it outside the track or inside it for two quite different families from the same numbers, in diametral pitch or module.
Learn one and you know most of the other: colour, fade, layers, animation, view and saving work the same way in both.

The other listings say "offline," but this one can't. The lab loads its 3D engine from the web each time it opens, so I left "offline" out and named the internet connection instead. If a buyer tries it offline, the 3D view will be blank.
