Tail Rib Jigs and HStab Rib

The last couple nights I’ve spent an hour here and there making the flange jigs for the horizontal stabilizer ribs and sanding the rough cut ribs to match the blue prints.

I used white glue on the first jig and it worked ok. The Gorilla Glue recommended was really the best and I glued all the rest of the jigs using that.

I used 2″ staples to hold the foam in place while drying.

After measuring, I found the 8 layers of duct tape put the flange spacing right at 5/16″, so I used 8 layers on all jigs.


The ribs sanded very easy, so I used 150 grit sandpaper to shape them. It was a. It slower, but easier to control so there was no oversanding. The results were quite satisfying and easy to achieve.

Cutting Tail Parts

Tonight I layed out the long H Stab and V Stab parts and got them glued down and cut out all the parts. Time, about 2 hours.

I just loosely cut out this template in the interest of time and it actually ended up making it easier to see the line when I was cutting them out.


All the parts for a complete horizontal and vertical stabilizer. They just need to be sanded to match each other so my wing surfaces are nice and flat and symmetrical.

Tae Kwon Do Testing

Today Jett went for his Tiger Brown and Journey went for her senior green belts. 

​​​

Jett was one of the best in the class. He kept his fighting under control and was able to do everything easily.

Journey did well in her form, but struggled with her contact skills. In sparring she was aggressive, but wasn’t using advanced striking.

Welder Upgrade

I’ve owned a Lincoln Weldpack 100 for some time now. Since day 1 I have always wished it could be a MIG welder. Inner shield is cheap and can make good welds. But comes at a price. It’s basically stick welding, so it’s messy. But if you do it right the slag falls off and a shiny weld is what’s underneath. Then you spend the next 10 minutes cleaning off you part. No longer! 


A peak under the hood of my welder reveals a 115v solenoid! I found this key complement on Amazon for $14.


My $14 solenoid valve with air fittings attached.

Parts list:

110v 60hz gas solenoid – Amazon, $14

1/4″ clear tube – Lowes about $1

1/4 bard x 1/4NPT – Lowes $5

1/4 NPT Brass street elbow – Lowes $5

1/4″ spade crimp connectors – free from my spare parts stock

Tiny hose clamps – free from spare parts stock

0.030″ contact tip – internet 12pack $5

1/2″ Gas nozzle –  internet $2

Screws for gas solenoid – free spare stock

CO2 regulator – Harbor Freight $27, this one sucked. Get it from Amazon for less and buy the adapter

I started by crimping my spade connectors to the solenoid. Then I used a paper to make a rubbing of the mounting bolt pattern on the solenoid.


I used a center punch to transfer than to the back of the welder case.


After the holes were drilled, I dug around in my spare bolts for 2 that fit and attached the solenoid. I then marked and drilled the hole for the gas inlet with a step drill.

I attached the spade connectors to the control board and hooked up the gas in and out lines. I also had to reverse the positive and ground leads to the gun. 


Hooked up the regulator and replace the wire, contact tip and gas nozzle. Done.
