Homemade powder trickle

Living in the year of the VID19 is hard, so I kept busy doing a little DIY projects. Made this powder trickle using a WST stop end 50mm female and upvc solvent 50X40mm reducer.
1-Used epoxy to fasten the two together.
2-filled the inside with expoxy resin.
3-smoothed the inside with dremel tool or manual labor will work aswell.
4-drilled 2holes on either side for alloy tube.(for this I used an old airial AKA BUNNY EYERS)
5-used dremel tool to cut away Grove on inside of caps to fit two 6.0x2.0 O-Rings.
Total cost R41-40
I think it looks OK and will do the job.

Looks good to me.

You may have to experiment with the hole size.

If the tube is smooth inside, it might just keep flowing with ball powders. Not that you need to trickle ball powders in the first place.

A storage lid may be worthwhile, to keep any dust or insects out.

👍🏼Thumbs up on the lid idea. Trickled some Hodgdon cfe pistol through it, it worked perfect. Not sure on other powders, but you have to work with what you have.

Great idea! CFE is a flaked powder so it'll work well. I would love to see how it performs with a spherical powder... :P

Great idea and it looks good.

For what it's worth - A spring from something like a ballpoint pen that fits inside the tube will help by creating an auger effect for the powder making it more controllable when trickling. I did that with my "el cheapo" that I bought - works like a charm.

Looks good, just a bit concerned about that powder hole is going to be too small for spherical powders. Generally trickles have quite a large feed area into the tube.

:t:

I do not have any experience with imported spherical powders, but I do know S341 and S121 is very similar in size. As such, I don't think the hole is too small for SA spherical powders.
