Spent some quality time in the shop.
I fired up both the 3D printer and CNC machine.

Started out printing some parts for my youngest sons plane. Nothing special, just a new battery box for his Slow Stick. Just under a 2 hour print. I had to file them down a bit to fit the boom. After about 10 min of work they fit. It holds the battery much better than the stock unit.

While the printer was running, I decided to make a few wing core test cuts with my CNC hot wire. My first two test cuts were only 9 inches wide. The cut path looked good. So I decided to up the wing span to 27 inches. Figuring the wingspan was wider, I decided to slow the feed rate down. I went from 3 IPM down to 1IPM. It turned out to be to slow. So I will be turning up the rate to 1.5IPM on the next test. Now all of this will change when I change over to EPP foam.

Regardless I'm making progress. And that's what counts.

Today was one of those days that you will remember for years.

A beautiful 82 degree day, a soft breeze, a small crowd at the field and good food on the grill. Nothing extra special about the day until 2-3pm.

My youngest son Michael has been wanting to fly. I like this idea. He took claim to his older brothers Slow Stick. So today he was determined he was going to fly it.

When time came for him to go out and fly. I was told by my oldest son, "dad, I got this". It was such a cool thing to see my oldest son helping my youngest fly for the first time.

Made me proud.

I'm pretty excited about this.
Through a friend of a friend. A research doctor from Hopkins has contacted me. He is interested in my CNC machine. He has asked me if I would be willing to cut some wing cores for him. It doesn't sound like we are going to be setting the world on fire. But never the less, I'm excited to be helping him. And hopefully learning something as well.

It has been two weeks now. I'm settling in to my new work schedule. I have to say, I'm liking it. Not real fond of the 6 days a week. But it really isn't that bad.
In the past two weeks I have managed to get a few things done. I cut the new letters for the clubs shelter at the field,, I managed to fire up the 3D printer for a small fidget for my daughter. I have also cleaned my shop. (it needed it badly) I found the new replacement flight board for one of my quads. So I hope to get that in the air soon. I want to cut a new set of wings for a plane. The new wing will be flat with ailerons. Thus making it a 4 ch plane. I have also started to take a much closer look at the drawings for a new build. I want to cut most of the parts on my CNC machine. I haven't decided on how I am going to go about it yet.

So with more than a few set backs. And a work schedule that makes it hard to get work done. I am making a few changes to my work schedule. Hopefully I will be able to get back into the shop and back to working on RC projects. I have more than a few piles of projects that need attention. Plus a very large build I want to start. Hopefully sooner than later.

A little more practice printing. Just a key chain.

Nothing special.

Just a small flat lid being printed on my new 3D printer. Being very new to the 3D printing world. I am using free files that I have found on line. Once I get more comfortable. I will start with my own designs.

Well, as if I don't have enough things going on right now. And my time being consumed with family and work 90% of the time. I came up with the brilliant idea of needing a new toy.

So I ordered a small 3D printer. I have been thinking about getting one for a while now. I finally decided to pull the trigger and get one.
I ordered one off Amazon for just under $300 It is made by XYZ printing. The Da Vinci Mini. It has a 5.9 x 5.9 x 5.9 working area. Not the biggest, but a good starter machine. I have only made a few small test prints. So far it has been fairly easy. A plug and play system just as advertised. I'm looking forward to making some bigger prints along with some of my own designs.

Is it a decent machine? So far. Is it the best? Probably not. Is it worth the money? Yea, I think so. If nothing else, it is a not to overly expensive way to get into 3D printing.

I was looking for a nice starter machine. Time will tell.

Back before I left for the NEAT Fair 2016.

I built a portable battery box. I wanted something I could take to the field and charge any battery back needed. I also wanted to be able to recharge the batteries with solar power.

The following is a very quick slideshow of what I came up with. The entire project was put together with spare parts and scraps.

So with the start of a new job Yesterday. My new work schedule does not allow a lot of free time for the hobby. So work on the Lady Bug will be on hold for a bit. I still want to finish it by years end. But in all honesty I don't see that happening.

Ok, Another quick video. I am sorry for it not having sound. (my first time using this webcam)

I cut the Vertical stab and rudder. I had to recut the rudder. The foam popped up and the bit hit it on the way across. The second pas went much better.

The rudder is 15.92 inches tall.

Nothing new over the last few days. Work seems to get in the way now and then.

I am working on the electronics side of things. Servo tray, motor mount, battery hatch and so on. I am also working on placement for proper CG.

I have a stack of foam waiting to be cut. New formers, top and bottom skins, rudder and vertical stabilizer.

I hope to be back in the shop later this week. If it's going to rain. Then I might as well be stuck in the shop.

Here is a quick video of my CNC machine cutting a fuse side. Nothing fancy.

Today was a semi productive day. I cut out two new fuse sides on the CNC machine. My first set were test cuts and missing the holes for the wing hold down and axel. I also modified the fuse a bit. I made it about an inch longer. I also changed the front firewall to fit the motor better.
I still need to cut doublers for inside the fuse. I want to strengthen the area around the wing hold down and axel area.
There is still a lot of things to do. I need to cut new formers with holes for the control rods to pass through. I also need to cut the vertical stab and rudder along with the top and bottom skins.
But at least it is starting to look like a plane.

I have made a little progress.

I glued all the wing ribs in place and have installed the spar. I also glued the wing tip supports on as well.

Had the CNC machine up and running this afternoon. I had previously cut the wing panels for a plane. I decided that I needed to cut a few slots to help it fold over the ribs.
I made a test cut on some scrap foam. It looked good and I was happy with how it turned out. My first cut of the left wing half went fine. The right wing half did not work out so well. I did not account for the inconsistencies of the foam. So basically it cut all the way through in a few spots.
I could have set the cut deeper but did not think it was needed with the foam so thin to begin with.
I thought about cutting the full length of the wing as one cut. I was afraid the panels would move during the cut. And I am pretty sure it will not like the blue painters tape holding it all together.
So here is my first attempt at making a large foam wing.

With a little family down time today. I decided to try and recut two more pilot figures.

With the summer break and the kids out of school. It is time for a break from the CNC machine. I am still working on drawings in Sketchup when I have time. If it is something simple that does not require a lot of machine time. I will try to cut something. I do have some cool things that I am working on.

My first attempt at cutting the pilot figure was going so well. I got down to the last 10-15 min and the bit got driven into the table. I don't believe it is the machines fault. I am fairly confident it is the program. Seeing as how it is not mine and I did not write it. I did a manual hot wire cut so I could at least remove it from the rest of the block.
Oh well, it's a start.

WOW, what a difference a few bearings make. (15 in all) I can not believe how smooth the movement is now.

I had a small issue removing the mill head from the gantry. After that the job went smoothly. No where near as bad as I thought it would be. After each axis was upgraded. I rebooted the machine and did a test jog. I learned a lesson a long time ago. Only make 1 change at a time.

The only thing that changed was I needed to readjust a limit switch on the V carriage assembly. I must have bumped it or something. After a quick readjust, I rehomed the machine. Smooth, that's all I can say. A lot quieter as well. I have a small issue with the W tower. but I am confident it will be a quick fix.

I hope to be up and running by Tuesday of this week.
