Spray Paint Can Shaker - Prototype I

Spray Paint Can Shaker – Designed to run on my drill press. It’s made from 3/4” Red Wood ply and Walnut for the hardwood “wear” pieces. It uses a simple offset circle for the cam. The cam follower is a 1/4×5/8×7/16 steel ball bearing mounted into a 3/4×3/4×4-1/2 length of walnut.

For prototype I, it works surprisingly well. It works best when running at about 17 hz on the drill press.

I have one design problem that I have yet to sort out. The rod coupler that I’m using for the drill press to bite onto seems to slip when running. Which in turn is causing the nylock nut on the outside to tighten. It may just be the nylock nut tightening up on it’s own, I’m not certain yet but when it does, it makes the cam assembly way to tight and will eventually lock up. I may need to drill and pin the rod coupler through the threaded rod so that it can’t move. Don’t know yet…

I did forget about milling the groves in the sides so the lower assembly would be “captured.” I’m not sure now how to go about milling them but it works never the less. I was concerned that the lower assembly would have a tendency to push out and go flying across the shop. But it stays in place quite nicely. It makes loading the can a bit tricky though.

I hope I can get the design problems sort out because man how I hate shaking “rattlers!”

Thanks for posting. I like to see ingenuity like this but I thought that’s what kids are for. I don’t think I’d want to subject my DP to all that vibration. Bently, that’s worth going to HF and picking up a cheap sawzall for. Way cool.

Another way is to wrap it in a pillow case, secure it with a couple rubber bands, and throw it in the dryer on ‘No Heat’ for a few minutes.

@Earlextech: Apparently so. lol

@bentlyj: The ole paint can taped to the sawzall trick works well. The draw back is, is that you’re still stuck holding the sawzall until the can is mixed. I’m hoping that with something like this, while the can is mixing, I can be doing something else, like preparing to spray. Yeah that sounds about right and not making me sound lazy at all. :)

@rance: I think you’d be surprised by how little vibration there really is with the DP set at 17 hz. Now if I crank the hz up on the dp and really get her signing, I think it would shake the dp into small pieces. BTW: 17hz is somewhere around 450 rpm give or take.

Looks like it should work, but how many cans could you shake while building this? ;-))

@TopamaxSurvivor: If you shake a can for 5 minutes each and we include the design and build times into the equation. Now lets see… A TRUCK LOAD of cans! lol

@dakremer: Not likely. I don’t have a proper video camera. I could use my phone but it’s so crappy you’d better off not having a video at all. I’ve been considering it. If I can get the tightening issue sort out, I’ll see if I can rig up something. No promises.

I may have the tightening issue fixed. I drilled a hole through the rod coupler and the all thread just big enough for a finish nail. I know, not the best thing in the word but when it comes to prototyping, use what’s at hand.

Ok a REAL crappy 12 second video from my digital camera. It is what it is.

Dang it. A cheap alternative a month too late. I just got done buying a $400.00 spray paint can shaker at Home Depot.
Thanks for the post anyway.

@Tim: It wasn’t over-engineered, it was over-built. ;) I designed it using all 1/2 ply but when I started building…

@CountryWoodCrafts: It sounds a lot louder in the vid than it does live in person. Don’t get me wrong, it makes a goodly amount of noise, but you could have a normal conversation while it was shaking w/out any problem.
