Prototypes: the first part from an idea

Drawings can hide problems. A part that looks right on a screen can foul a neighbor, miss a clearance or feel wrong in the hand. Making one is the quickest way to find out. Prototype work is where the shop's willingness to help with design matters, because the idea is often still taking shape.

At a glance

• One-off first parts from a sketch, sample or CAD file
• Changes between versions without starting over
• Design help while the idea is still moving
• A smooth step to production when the part is proven

What should you expect from a prototype?

Expect to learn something. The first part tells you which dimension was wrong, which clearance was tight, and which feature you did not need. A good prototype run assumes there will be a second version, so the shop keeps the notes and measurements from the first.

Because it is a single part, the cost of finding a problem is small. Finding the same problem after fifty parts is a different matter.

From idea to drawing to production

Many prototypes begin without a drawing. You bring a sketch, a sample from a similar product, or a model. The shop machines the first part, you test it, and the changes are marked on the part or the sketch. By the second version, a proper print can usually be written down.

That print is the bridge to quantity. A part with a drawing, a known material and a proven fit moves smoothly into production runs, and the prototype to production article shows the steps in between.

Private projects are welcome

Prototype work is not only for companies. A Google reviewer who builds an ultralight aircraft wrote: "I have used Wolf Machine several times over the past few years for fabricating and repair of parts on my ultralight aircraft. ... the work has always been top notch. These guys are great to deal with. I wouldn't take my projects anywhere else."

If you are building something of your own, a vehicle, a hobby machine or a test rig, say so in the quote request. A one-off project is a normal job.

Starting a prototype

Tell us what the part does, what it connects to, and what material you would like to try. A sketch with the key dimensions, a CAD file or a sample is enough. Use the quote request, or call (775) 359-5570, Monday to Friday, 7:00 am to 3:30 pm, and we will talk through the part. You can also read more about design help and parts made from samples.
