  • 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

Safety concerns
Style: Corded
The variable speed when base is nice and works very well. However the flexible accessory shaft has a major design flaw., there is no locking mechanism on the flexible shaft making it impossible to tighten the collet down to hold the bit in place. Making it easy for the bit to come out of the flexible shaft while it is rotating at any speed.

For the money this is amazing!
Style: Corded
I love this rotary tool. Mind you it’s not a 150$+ dremmel but it is a workhorse and very reliable. I see these comments of disappointed people saying it’s not up to there standards and there dremmel is better. I don’t understand that. This is a 20$ rotary tool and the best one for that price you can find. Most of these reviews are comparing to high end expensive dremmels and that doesn’t make sense to me. Anyway I like the rotary tool very much and the first thing I did was buy the keyless Chuck made by wen so I don’t have to deal with collets and have them wear out or keep changing them when I need to use a different size bit. Best investment I made. Makes life so much easier. I ended up buying 2, one for the rotary and one for the flex shaft. Also if you have never used a flex shaft you need to understand that you have to take the collar off and slide the insert out of the flex shaft so you can clamp the rotary tool on it and then screw it on where you removed the collar. I recommend every 20 to 30 hours of use with the flex shaft take the insert out and wipe the grease off and reapply a light amount of grease. That way it doesn’t heat up. I’ve found that with this particular flex shaft graphite does not work so well like other models. It will get hot with graphite. I’ve found that Valvoline red high temp bearing grease works the absolute best. You can buy it in the tube here on Amazon or at you’re local auto parts store. The high temp is what you need and it prevents grease from melting down into the handle of the flex shaft. All in all this is a win win if you understand how to maintain and take care of it. I originally got one of these because my grandfather has one and it’s over 12 years old and it’s still working. Probably has a couple thousand hours of use on his. Take care of you’re stuff it will take care of you…

With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride. Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives. Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle.

Good quality sound deadener at a good price.
Model: NewSLS50_52
Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.
