    I was looking at some case trimmers (maybe not the exact term for all the things I’m looking at) but I think Horandy makes 1 or 2 that have 2 or 3 heads where you put the case head on it, the “bit” spins and it removes burrs and smooths out the case & maybe rounds it out. I saw one listed for $200 and it seems like an awful lot for a motor that turns a bit. I was wondering if things like this could be made with commonly available tools like rotary tools (dremel & the like – or even a drill).


    I’ve seen many other things, especially digital scales that seem to be much more expensive than what you can find from surplus lab sales where I found a scale (near $3K brand new) that I picked up for $85 at a liquidation auction (and there were about 20-30 more of he same scale for sale). This weighs down to micrograms ( 500 mcg – .008 grains) and this scale can go up to 200 grams and has 10 different calibrations like grams, karatz, troy oz, oz, grains, mg, mcg and others I’m not sure what they are. It’s super fast and I’ve never had an off reading. Has self leveling legs and you can add an enclosure if you are worried about air turbulance throwing stuff off (I made an enclosure for $10 from lexan/polycarb that can fit a trickler in it & have door to open to remove dish). This has come in handy for MANY more things as well.

    I’m just curious if there are other things people have made themselves to aid in reloading, maybe to avoid paying the premiums for some stuff (esp last year), or to use other tools they have & just a little mod to make them useful for reloading.

    I’d love to get a list of things that people have come up with to save $ and maybe even get better results.

    My current projects are a vibrator and also a tumbler and have found scrap motors that give adjustable speeds (can go well above or below commercial products) and could handle much larger capacities than commercial products. I’m using an old “sawzall” for the vibrator and I can control how the vibration range from ~2mm up to 1.5″ – and I found that the springs (all being of equal strength, lenght & tension) eliminate the VAST amount of work the motor needs to do – as the springs self correct in any direction the container moves (it’s suspended at 8 equidistant corners). This is compared to vibrators that are vertically mounted (sitting) on springs where it seems the motors have to work much harder for the same amount of movement (and it is actually more complex to design it seems). Maybe this is why these types of vibrators burn out more often (underpowered motors or just over-worked??).

    So does anyone have anything they’d like to share or add?

    I built a wet tumbler and can do a few thousand 9mm at a time. It was cheaper then the Frankford arsenal because I had most of what I needed in parts already. I also can fix it easily cause I made it.
    I also 3d printed a case feeder collator and bullet collator.

    I think you should take a look at one first. My FA weighs a ton because it had a big high torque motor. A dremel can’t substitute for that.

    A similar sized and output electric motor isn’t cheap, and then you have to fabricate the gear train and belt train and the housing. Not a money or time saving project.

    >reinvented the vibratory tumbler

    The reason why this design is ubiquitous from small vibe tumblers all the way up through industrial tumblers is that the motor isn’t stressed – it is only inputting power to a system that is resonating. Your design involves using the motor to forcibly shake the bowl and fight the spring loads.

    This is very apparent when you turn it on because the media cycles like a standing wave while the bowl is moving.

    The reason why they burn up is that they are made in china.

    I 3D print cups and funnels, trays for good fit.

    I made a few tools.

    Crimped primer decapping tool:

    Custom powder dippers:

    Shoulder position tool:

    Join the Discord channel and there is a 3D Printing room on there that has a link to a bunch of reloading related 3D models that members have designed and proven out and offered the models to download for other to print.

    Have you started playing with Stepper Motors yet? Those would make an interesting alternative to traditional motors.

    Coupled with sensors they could turn on and off so only in use while you are trimming/champfering, etc

    The other thought I had was using a pneumatic ram to run the press for me.

    I printed a couple of tool heads for low power operations. I have one for pulling bullets and one for decapping. I have a bunch of toolhead stands that I printed. I printed out a primer tube filler too.

    I thought about fuckin with making my own knock off of the Frankford arsenal case trim center, but it becomes prohibitively expensive if y[u have to buy all the parts.
