  • 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

Tastes Like Banana Pudding and Dunkin Banana Flavor!
Flavor Name: Banana Bread, Size: 25.4 Fl Oz (Pack of 1)
I don't know why someone would buy this expecting it to taste like real bananas like come on ppl lol. The only way to attain a syrup that tastes like real banana bread is to make it at home. This is an artificially flavored syrup so obviously it tastes that way! I have made banana bread syrup (more like a sauce) at home and it is delicious, highly recommend!! But this is way more shelf stable and tastes amazing in an iced latte as well! Different than home made but still good. To me this tastes like banana pudding mix which also has a fake banana taste. It also tastes EXACTLY like the new Dunkin banana flavored syrup which is what I was looking for! I use 1.5 tbsp syrup, a little vanilla paste, 2 espresso shots and 2 percent milk with plenty of ice. I like keeping my latte calories below 200 and not super sweet tho so you can up it to 2 tbsp. The cals in this are not terrible, 70 cals for 2 tablespoons. Usually my syrups have 50-60 cals for only 1 tbsp so I'm pleasantly surprised this is a little lower. I bought a second bottle because I'm afraid this is a limited release lol.

Worth it!
Flavor Name: Coconut, Size: 25.4 Fl Oz (Pack of 1)
Compared to Torani syrups I prefer this one for my coffee in the morning. It’s soft, smoother and tastes delicious combined with cream. You get a lot for the price you pay and it lasts.

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.
