October Update

Things are going good. Things are busier than hell and I’ve been working on a few things. Firstly, I’ve been doing woodworking as an interesting departure from what I do on a daily basis. There’s a particular sense of accomplishment in having a usable item ready to use after a few hours of work.

A little work area I’ve set up in the mezzanine of the shop.

So, I’ve also been working on more boxes for use on our products. Hopefully they look good enough and will be better than us sending things out in cardboard or some makeshift case.

A bunch of boxes for our setting masters

It should also be said that I bought a junky little 3018 pro CNC machine off amazon for laser engraving paddle gages and setting masters and whatnot. The machine initially ran like shit, the bearings on the Y axis were some of the worst garbage I’ve seen in a while. I polished the linear rod down a bit and trued up the bearing blocks so that they’re in line with the rods. This however only made it a bit better. I may buy some decent bearings at some point.

Also, I’ve taken a few more steps to completing a prototype version of my goofy digital LED clock. This was done with a 16×16 matrix of ws2812 LED’s. You can pick these up for like 15 bucks CAD. They’re an interesting display if anything.

The back end of the clock.
Obviously, the protective layer on the plastic hasn’t been removed yet. I figured that putting some translucent plastic over top of the display would make it a bit less hard on the eyes when looking directly at it.

Well, there we go. Perhaps more will occur this month.

12 years at Rejent. Now moving.

Well, I’ve been here at Rejent on and off for the last 12 years. Now the company is moving to different digs and I figured I’d take some arguably unflattering pictures of the shop. Things are in disarray and thigs are a bit dirty as well.

Right now these things seem mundane but in 20 or 40 years there will be somebody, perhaps even myself who will enjoy looking at photos like these. Our new place will be in the old Precimax building and while it doesn’t have that much more room, it will be a fresh start and we can organize things with a pinch of pride.

Here’s to a good move!

New Linear Gages are ready to go.

We’ve had these things in waiting for quite some time. I’ve designed them to be lighter, more accurate, less snaggy and a bit sleeker. They take the standard heads that I’ve made for the last 4 years and still move linearly so that you can put whatever kind of styli you want on them. The older ones used to snag due to the fact that there were two bearing being forced to cock over in certain circumstances.

A view of the working end of the gage

As things heat up in the world and the economy either booms or busts, hopefully we’ll be able sell some!

The Gages are complete and ready to ship

After a bit of work and worry, the gages are ready for shipment and are as nice as I could hope for.

I’m quite proud of these, they’re repeatable and feel damned good in the hands.

Some new DNMG boring heads I designed

Well, the new boring heads I designed came out well, especially after nitriding. Man! is that black finish ever nice! I’ve made many heads before but these turned out nicer than usual.

The whole order

The backwards dnmg holder

Well, things are getting busy, I’m sure there will be more to post soon, especially as our gages get done!

The new gage!

Well, the prototype gage is here and it seems to work reasonably well. I’ve given it extra travel over the old ones and it seems to have really nice, smooth action.

Here are some pics

Now to make some styluses and start shipping these things around the world!

New Youtube Channel for a new time

I’ve decided to start a new Youtube channel simply because I feel as though adding my projects and the things that I like to a video channel will drive me in ways I hadn’t had before. Thus far, I have 0 subscribers (aside from myself) and I’m genuinely curious to see how well I can make a Youtube channel work out. I believe I have some interesting things to share and some boring but popular things to share as well and a new Youtube channel that explores all those things.

Here’s a link to the channel

https://www.youtube.com/channel/UCwxvlEKdkh9eV9qLXHBh3fw

Not the most graceful URL but I will get a better one once I get some subscribers and I’ve been around for a while. I will explore things that I do such as electronics, gaming, machining, photography and whatever else I come across.

Here’s a video detailing something mundane, my calculator collection.

So, feel free to look at my channel, subscribe and like a video or two. 🙂

The Remote-a-cator

Well, the first project out of my little skunkworks is ready for doing the electrical side now. here are some shots of the device.

It’s been a bit of work getting everything together but thanks to having a decent work space, I can finally let my ideas become reality.

Diminutive, a small EDM prototype

For the last little bit I’ve been working on a small EDM prototype for use on large parts, pipe sections or for use in the field. While they do make and sell these things, the vast majority of them require the use of vibratory assistance, aren’t terribly accurate and are relatively low powered. I intend to make one that is accurate and could potentially be used as a ram EDM in a pinch. Also, I’d like it to be able to use copper and graphite electrodes so polarity reversal is necessary.

This is the linear drive of the small EDM. It has 8 inches of travel and is surprisingly rigid and play-free. I was going to use a gear motor on the top with a rotary encoder but since the loads are quite small a stepper should be OK, even at higher speeds.

I’m currently trying to come up with ways to mount this guy on magnetic bases but also allow for small amounts of fine adjustment so that if there is a need for precision work, the unit can be dialed in. Right now the coupling is made of two pieces of steel. I’m going to replace one of them with nylon to reduce noise. I was going to use a spider coupler with rubber in between but I didn’t have one kicking around on the weekend when I was making it so I just made my own.

It's all made from 7075 aircraft aluminum. Pretty strong stuff. The movement was initially pretty stiff because the screw, which is just hot rolled, was a little bit out so I had to run it back and forth to wear in the brass acme nut. I may put two acme nuts into the travel block simply to take up play, as it stands though right now there is less tan .0003" of play, even with significant force applied.

So next things next, the prototype electronics. Right now I’m simply going to use what I have laying around, so a TM1638 display, a cheap chinese stepper driver with a toshiba stepper driver and I opted for an Arduino to drive the motor. I will be making a full fledged PCB that will nicely fit in a box but I need to get the pulse generator and sensory circuits working first, then I can integrate them fully on to one PCB.

Just a rough testbed for the motion control and a simple interface. I would like this thing to be nice and easy to use.

Well, anyways, I have quite a bit more work to do for this project. Even a single axis CNC can be a little more tricky since it’s doing more than simply positioning. A ram EDM is a dynamic machine that reacts to the sensory input to keep the cut running smoothly and with appropriate voltage and gap settings.

More later.

Three years at Rejent!

Well, It’s been three years at Rejent (plus a week). Since I haven’t updated in a while I figured I’d go through some of my Solidworks files and post a few of the things I’ve worked on during my time here. After looking through the files I am quite amazed at how freakin’ many parts I’ve worked on over the time I’ve been here. Hundreds of different things!

Anyways, here are some pics of a few things I’ve worked on during my time here, albeit a very limited selection of them.

That was just a few of them that I randomly found, nothing too crazy since some of I couldn’t really show. Well, let’s see what the next few years brings.

The project is finished! And other goings on.

I have just finished the project that has taken up the last 3 months. Delivered to the customer and they are very happy with it.

A view from above on the two sizes we made for the customer.

I’m so glad to be done this project. While it wasn’t a terribly long project, I’m glad it all went off without any real problems. It measures better than they’d hoped and it’s a pretty attractive little package, for what it is. Next iterations will be significantly smaller and I will look at new encoders to use.

Also, as an aside I have set up my new office. It’s nice to get out of the basement. I now have a lot of free room now so it’s nice to spread out and be able to sort through all my shit and set it up as efficiently (for me) as possible.

This is my new office for 2013. I have a new computer coming soon.

Final version of Digital Gage almost done!

This device is almost complete. Yes, It’s missing its buttons but the device seems to work well and nice and smooth. The real anvils are almost done and the device will ship to our customer fairly soon and I’m glad to see these guys be done!

DigiGage top Digigage from the right Digigage from the top panelThere are still some tweaks to make especially in the realm of overall rigidity but overall it’ll be a neat device to attempt to bring to market in different ways.
