TinkerMill is a community of people with a vast range of interests that are represented by the shops we maintain. Each is run by members of TinkerMill who volunteer their time, energy, and skills putting together a shop, operating it, training new members and the public in how to use the tools, and develop the skills needed to create with those tools. They are the ‘Shop Captain’. 

We have the shops that we do because our members want them to be here. Below are the shops we have currently.

Shops you’ll find at TinkerMill today:

TinkerMill’s Electronics Shop has a well equipped area for member use. Long time members with many small projects, or product developers doing something absolutely new – gather in the TinkerMill Electronics Area. More than just the availability of technology for testing, there are like minded interesting people to find collaboration with. With an open layout, people ‘working’ in electronics are in visual and verbal communication with other unrelated areas. Electronics is bordered by the metalwork area and the overhead doors in the Main Space. It is the first area past the entry.

Flameworking uses a torch to heat up glass to make it molten. In that soft state you work the glass with tools and glass to create art.


  • Bench Burner – A torch that is fixed to the bench which provides a stationary flame.
  • Didymium Safety Glasses – Glasses that provide a filter which selectively blocks the yellowish light at 589 nm emitted by the hot sodium in the glass, without having a detrimental effect on general vision, unlike dark welder’s glasses. The strong infrared light emitted by the super-heated forge gases and insulation lining the forge walls is also blocked thereby saving the lampworker’s eyes from serious cumulative damage.
  • Hand Torch – The hand torch allows for more maneuverability of the flame, commonly used on glassworking lathes where there is reduced maneuverability of the piece
  • Kiln – the kiln is used to garage and anneal the glass, protecting the piece from thermal shock and relieving thermal stress.
  • Marver – flat surfaces used to roll glass upon in order to shape, smooth or consolidate applied decoration, typically made of graphite or steel.
  • Paddle – A graphite or metal marver attached to a handle
    Reamer – A piece of graphite or brass on a handle used to enlarge holes.
  • Blowhose/Swivel Assembly – A hose, usually latex, is connected to the blowpipe via a hollow swivel, allowing the lampworker to blow into hollow glass forms while rotating them.
  • Tungsten Pick – The extreme temperature resistance of tungsten makes it ideal for raking(dragging glass around on the surface), or to bore a hole through the glass.
  • Shears – Steel shears are used to cut the hot glass.
  • Hot Fingers – Metal tool found in various configurations which allows the hot glass to be securely held and rotated, commonly used for finishing pieces after they have been removed from the blowpipe or pontil.
  • Pontil (Punty) – A small diameter glass rod used to hold a piece while working on it. The end of the punty is heated, melted, and then secured to the work piece. Later, the cold joint connecting the work piece and the punty can be broken with a light tap on a solid surface. It often leaves an irregular or ring-shaped scar on the base when removed called the “pontil mark”.

TinkerMill’s machine shop is a great place for shaping metal and some plastics in a controlled way.

  • Drill Press
  • Pedestal Grinder
  • Deckle single flute grinder
  • Bovar-Schultz Challenge 6-18 Hydraulic Surface Grinder
  • 52″ sheet metal roll/press brake/shear tool

Our Metalcraft, Jewelry, and Lapidary Shop is dedicated to working with non-ferrous metals to craft jewelry, art, and other relatively small items. Metals that can be used in this shop are brass, bronze, copper, silver, and gold. (Steel, titanium, paladium, aluminum, platinum, and other metals are currently not supported in this shop.) 

Here is a short list of both decorative and functional skills you can learn and practice at our shop:

  • Wire work: braiding, wrapping, chain-maille, jewelry findings, beading
  • Forming and shaping metal: jewelry, vessels, small home decor items
  • Joining metal: soldering, cold connections such as rivets, hinges, latches
  • Decorating metal: pierci
  • ng, texturing, stamping, enameling, imprinting, coloring, etching
  • Casting and sculpting
  • … and more. If you have a request for a class or have a specific question, please send a note to the shop captain.

Please come, learn, and create something cool at the Metalcraft and Jewelry Open Studio. The Open Studio is perfect for exploring the shop, getting acquainted with others with similar interests, and asking questions. Do you have a craft or piece of jewelry you’d like to make using metal, but not sure how to begin? Someone with experience will be around to help you get familiar with the tools available and how to use them. The Open Studio is very informal but please use the Meetup calendar to verify the next Open Studio date and sign-up to let the shop captain(s) know you are coming.

For more information about the Metalcraft, Jewelry & Lapidary Shop, please visit our page on the TinkerMill Wiki.

Our pottery studio is a cooperative space where we as a community strive to maintain a functional and safe environment. We have wheels, hand building tools, clay, glaze, and kilns. 

Respect for each other, the studio, and Tinkermill as a whole is very important.
With that in mind, we ask that you read and agree to the General Studio Policies

Additional shops:

Amateur Radio-

Tinkermill’s HAM Radio has the best station inside the Longmont City limits for working DX and is definitely within the top 10 stations in Boulder county in that regard.

The main antenna is a Mosley Pro-67 mounted at 65 feet on a Rohn-25G tower. This antenna covers 40m (3el), 30m (1el), 20m (3el), 17m (2el), 15m(3el), 12m (2el) and 10m (4el). The antenna is turned with a Yaesu G2800 rotor. We also have 2 dipole antennas for 80 amd 160m.

The shack is continually under construction and the next steps would be to add remote control for antenna switching and rotor control. We also need to get 208V installed to run an amplifier.

Existing equipment:
  • Flex-6400 SDR.
  • Kenwood TS-440S Radio.
  • Dell Computer with dual 1920 x 1080 displays.
  • Astron 35A 13.8V Power supply.
  • MFJ-1128 Power strip with Anderson Power pole connectors.
  • LP-100 Power Meter.

The foundry can used to cast aluminum using a sand cast mold system. 

To use the foundry independently, two people must be present. Both the person pouring and the person who is the safety backup person must have completed the safety certification course.

To be fully certified, the certification class and four independent pours are required. Often these can happen during the certification class. If not, there are always pour times set up at the end of every certification class for this purpose. 


Paint Booth-

TinkerMill has a small paint booth to finish your creations. We limit the material to latex based finishes.
