  • Description
  • Gear stock is perfect for creating custom sized gears, or up-integrating shaft features to reduce part count in assemblies. It can be loaded into a lathe or mill and machined to any number of shapes and given any number of bores to meet your specific needs.

    Some examples of what you can do when designing with gear stock as opposed to off the shelf gears include am-3013b and am-3018b.

    All the gear stock that AndyMark utilizes to create our fully machined gears are listed and available here. These are sold in 1 foot (12 inch) sections, but if you require a longer section or a gear profile we do not currently offer, please contact us at [email protected].

    Selecting a Gear Stock

    Tooth Profile

    First, and most importantly, the tooth profile. If you are interfacing with another gear you need to know its Diametral Pitch (DP, for imperial gears) or Module (MOD, for metric gears). This number governs the size of the tooth, and meshing gears must have the same size tooth. Within these sizes there can be various pressure angles. These also need to match for meshing gears. To avoid confusion we do not sell gear stocks with the same "tooth size" and different pressure angles and for this reason we have combined these 2 parameters into one dropdown. In FRC 20 DP, 14.5° PA is the most common, followed by 32 DP, 20° PA. The rest of our gear stocks are used in specialty applications.

    Tooth Count

    Next, you will want to select tooth count. We have many options here and this is usually dictated by your design and what gear ratio you want to achieve, or which gear you may be trying to replace. Note that tooth count directly affects gear diameter, so if you need to put a specific size shaft through the gear you are picking make sure the gear is going to be large enough. All the CAD files for all these gear profiles are available at the bottom of this page.

    Material

    After specifying the above parameters you will be presented with a list of available materials available for those options. If you require your gear to be a specific material specify this first and the other options will narrow to ones that are available in this material. If you are curious about the specific alloy number of the material selected (for example 6061 Aluminum or 4140 Steel) check the part number that is generated below the last dropdown. The 4 digit number near the end is the alloy number.

    Part Number

    Once you have made a selection in each of the options you will be given a part number. This number contains all the information you selected above and can be used to locate the appropriate CAD file below. If you would like to interpret the number, it is set up as follows:

    gs-P-S-T-A-1
    gs - indicates Gear Stock
    P - indicates the Pressure Angle
    S - indicates Diametral Pitch or Module
    T - indicates Tooth Count
    A - indicates Alloy Number of the Material
    1 - indicates the length (in feet) of your piece of stock

Absolute Game Changer for Wine Nights!
Color: 5-in-1 Black/Decanter, Size: Rechargeable Set
I am completely in love with this 5-in-1 electric wine opener set! It has completely taken the struggle out of opening wine bottles. What Makes It Amazing: Effortless Opening: The electric corkscrew is incredibly powerful and smooth. You just place it over the bottle, press down, and it removes the cork in seconds without any pulling, tugging, or broken cork pieces. Instant Aeration: The electric aerator and pourer is a massive standout. It micro-oxygenates the wine right as you pour, instantly opening up the flavors and aromas so you don't have to wait 30–40 minutes for a traditional decanter to work. Smart Preservation: The included vacuum stopper works wonderfully to pump out excess air, keeping leftovers tasting fresh for days. Convenient USB-C Charging: I love that both the opener and decanter are rechargeable via Type-C. A single charge lasts for dozens of bottles, so it’s always ready to go when hosting. The entire set feels lightweight yet highly durable, sleek, and looks beautiful on the counter. It includes everything you need from a clean foil cutter to the dispenser. It would make an incredible gift for any wine lover, but it’s an absolute must-have for your own home bar!

Opener works well and the aerator is so handy to use
Color: 5-in-1 Black/Decanter, Size: Rechargeable Set, Color: 5-in-1 Black/Decanter, Size: Rechargeable Set
So easy to use! This set comes with everything you need to enjoy a nice glass of wine (except the glass and wine itself). lol The bottle foil cutter works very well and is easy to use. The wine opener grabs ahold of the cork all the way down to the bottom of the cork and pulls it out with no issues or breakage. The wine aerator is fabulous and you can really taste the difference in the wine after using it. The silicone cork that it comes with, has a pump feature that allows you to remove some of the excess air in the unused portion of the bottle. This helps your wine last longer until you were ready to drink the remainder. Each accessory is lightweight yet feels very durable. This is so convenient and so so much easier than having to manually remove the cork from a wine bottle. Very pleased with everything in this set!
