I don't know that I have ever talked about this before, and perhaps I should have. Some time ago, we invested in two small vibratory tumblers. These tumblers are used to put a nice, smooth, uniform finish to the outside of just about any material. These tumblers worked great for some of our smaller parts, and we even tried it on our pedal faces (batch #1). We absolutely loved the surface finish that it gave, and it looks similar to galvanized metal. The problem is that our tumblers are not big enough to handle any parts bigger than about 3 inches in diameter. Therefore, we've decided to invest in an industrial vibratory tumbler. The one we have our eye on is able to tumble all of our larger pieces with ease.
So, what does this mean, exactly? Well, it's actually a significant change. What this means is that we will no longer have to handle any of our parts with regards to their surface finish. Basically, the tumbler does all the work, and the parts come out looking great. Here's an example of what the finish might look like. This is just an example of one type of finish you can achieve with a certain type of tumbling media. The surface on the left is plastic media, and the surface on the right is ceramic media. We will most likely be using ceramic media, as we prefer the finish it produces.
As you can see, the finish is quite good, and there's really nothing to it. You just drop the parts in, and the tumbler does the rest. In the long term, this will save us a significant amount of time. For example, it takes us at least a week to sand blast all of our parts for 36 pedal sets, if not longer. On top of that, before the parts are sand blasted, they have to be prepped with a cleaning solution, otherwise all of the dirt and grease will get blasted into the metal, and it's very difficult to clean it after the parts have been blasted. This tumbler will help eliminate both of those steps in the finishing process. This is definitely a step in the right direction for us. We need to get these things done much faster than we currently are, and this will help us do just that.
When we first announced these pedals, we wanted to have them powder coated, but once we started to do that, we quickly realized our mistake. I didn't want to make the decision to switch to sand blasting, but we had to do something. Things just weren't working out. Well, we're facing the same problem once again. This sand blasting thing just isn't working out. I'm having to stand at the sand blaster for hours and hours every day for at least a week, and it's starting to take it's toll. So, we're going to move in a different direction.
BATCH #4
We will be starting production on Batch #4 after the 1st of the year. In my last video, I explained that things were starting to get a little too hectic around here, and I took some time off. The biggest issue with that is that I didn't tell anyone, and I should have. I just want to apologize again for not letting anyone know about it. Anyhow, I'm going to be spending the holidays with my family, and I'm sure most of you can understand why.
So, between batch #3's release, and the start of batch #4, we will be installing the new tumbler, and also making some much needed changes to our milling machine and cnc machine. Our cnc machine is not as rigid as it could be, and the manufacturer has released a kit that really makes the thing much more rigid (this will allow us to complete parts faster). We've also invested in a belt drive kit for our milling machine. This will essentially double the RPM's on the machine, and eliminate those awful plastic gears (really, Grizzly? Plastic gears?).
Well, this post turned out to be much longer than I anticipated. I hope you guys can understand why we are making these changes, and I hope you will all bare with us as we spend a little quality time with the family, and get ready for batch #4 ;-)
If you guys have any questions, please feel free to ask. I'd be happy to answer any questions you may have.
