The XPB Stage 1 underway.


Recommended Posts

nice looking machine Bex.

 

Not arrived yet, don't care what it looks like as long as it performs. Hmm, I've said that before after a few drinks ...

 

More on the Elevators today, made the ribs up, and started adding the hinges ..

Today I made a quick rough as guts jig from some scrap laying around to help with some leading edges

 

2 pieces of 50mm/2" pipe, some 25mm/1" square and some gussets.

 

On the right is a piece of 32mm/1.25" pipe.

 

There's about a gap of 38mm/1.5" between the 50mm/2" pipes.

 

Note the end close to camera has a bar across the top, I call it the end with the bar across the top.

Note the other end does not have a bar across the top. I call it the end with no bar across the top so as to avoid confusion. I was considering to call this end Rupert, but finally decided on the former.

Center your work over the pipes.

 

138490430_jig3.jpg.8c8d8ea88693db3598034a069fd6d77d.jpg

 

 

Hook your 32mm/1.25" pipe (or smaller if you want sharper radius) under the bar.

Lever the pipe down all the way through the gap, I put a 25mm/1" tube inside the end for leverage, and once down all the way through, I stick another in the other end as well to push that one all the way down. But you need to hold the first tube down - you may need another person to help depending on length of your workpiece. Note that the lever pipe has no name.

I managed to lose the picture of the workpiece forced all the way down, so here's a Gay Spiderman dancing ...

So when you remove it, it will springback a bit. You can get a bit more bend by laying a few sheets of newspaper or cloth to tighten the gap some.

It's still a little big here.

So to pinch it further, a couple of anything suitable, square tubes here, and clamp then together, removing and checking as you go. Make sure you tap the workpiece down with your hand s you go as it can pop up in one corner as you squeeze.

You still here? What, you think there's more? What do you expect for nothing.

Trying to make headway with the Elevators

Anyway...

 

This morning I did the other side Elevator leading edge, so here's the picture to replace the one I lost yesterday with the workpiece fully pushed into the jig ..

 

This of course means no need for dancing Gay Spiderman (Sorry Kasper).

And the end result, 2 leading edges for the Elevators.

Here's a picture of a charming 1950s soviet era aircraft, thanks for the compliment ....

It has been bought to my attention this morning that a couple of Members here have been sharing a story about Chinese cutting up humans, and canning them as 'Corned Beef" for shipment to African Countries.

 

I have deeply investigated this today and want to offer assurances to those concerned that absolutely no children or dogs are being added.

 

....

 

Quite proud of myself today, I arrived at the factory in the morning with not a clue how I was going to balance the Elevators, and by the end of not only figured it, but had 90% of it finished.

 

I grabbed a 25mm (1") square tube, cut some 19mm (3/4") flat steel and slid them inside the tube,

552449799_Balance3.jpg.2c68c01864392798b42faedb38776a7f.jpg

 

... sat it on the Elevator and juggled the tube and the weights around a bit, until it balanced. Got to seek out a reasonable ratio of length and weights.

 

The longer the lever, the less weight, the shorter the lever, the more weight required. At first I settled on this ..

 

16447192_Balance2.jpg.169dca99c05bf5bb7c0da829d57e1355.jpg

 

But it was a bit long, so I got it a bit shorter by adding a couple more strips of steel on the outside (better fastener perch anyway), and now the Elevators sit where they are supposed to. They actually center themselves because the weight is a little below the hinge point.

 

1718882258_Balance5.jpg.6a58e03133cb6192c27700f1d055c33a.jpg

 

I will tidy it all up and make some fiberglass covers at a later date, not important for the moment.

I had to have a few days rest, recovery after last years open heart still takes a bit out of me, but getting there, just slower than I would have liked.

 

But anyway, enough of that, I don't want you guys to get all upset and misty eyed over me and start donating money, well ok, a little if you insist, I promise to not spend it on expensive whiskey - 12 year old will be just fine.

 

Yesterday and today I played around with the VS and Rudder, measuring and figuring how to operate it. I ended up adding an extra rib next to the one at the edge of the tail, slotting the rudder, and slipping a lever arm through to be sandwiched between them, and riveted in place. Worked out quite nicely, though I will be changing the lever arm out for a different shape one.

Bex, is the rudder only held in place by the rows of rivets either side, or is there a post I can't see linking it to the fuse?

 

You mean the VS?

 

If so there are 2 posts, one at the rear and one where the leading edge meets the fin, well there will be after i build them today, and you still won't be able to see them even when they are installed.

 

As soon as I am finished this bowl of Kerrogs K-Nine Cereal, it's off to the factory to make them.

There are more important, vital questions that need answering about this new design. 1. Is it safe? 2. Does it come with a guarantee to be virus-free? :cheezy grin:(questions courtesy of Diana Fisher of the ABC Inventors show)

 

I won't bother sending you any of my Glenfiddich, it may be quarantined and never reach you. I'll drink a toast to your good health with it, instead. :cheezy grin:

Sorry, yeah, was still half asleep. Obviously VS.

 

Does Kerrogs K-Nine contain traces of dog?

"What colours does it come in?" ....

 

 

Looking good, Bex. I might have missed that bit, but have you done aerodynamic testing of the design?

The slab sides would likely increase spin resistance.

 

Basic CFD. Some changes were made due to that.

 

 

Does Kerrogs K-Nine contain traces of dog?

 

Of course, but if that puts you off, try the Kerrogs Fee-Line.

I decided I need a C Channel and another part easiest to be made in fiberglass, so moulded up a 50mm/2" steel tube and pulled a piece

 

390578245_CChannel1.jpg.a808770f81270c9008ba0fd1b08e7c02.jpg

 

and handcrafted the other part which the mould will be ready tomorrow..

 

1383116140_CChannel3.jpg.7de5a53ad28d4738687c4a749eb58048.jpg

 

 

Preparing some Swiss-Cheesed floor runners, all press drilled, I don't mind it, but it's boring after the first hundred holes, so can't wait for my CNC Router to arrive soon ....

I see an issue with the virus that should be mentioned.

 

Some of you would note that the virus seems to be under control in China, well that's a truth that doesn't apply to most any other country in the world, and offers a false hope.

 

Most Chinese live in high rise apartments, in secured housing compounds, around 500 to 2000 people. With the virus crackdown, every home can only have one member leave per day, unless you have a work pass. Your temperature is tested at the gate when you leave, and when you come back in. Same when you arrive at work.

 

So anyone who's temp is up, are spotted immediately, and either self quarantined and observed, or off to hospital.

 

This simply isn't going to happen in many countries with individual housing, many people will go days before they realise they are sick. This is what's happening in Italy right now and why it's spreading so fast.

 

So please don't relax on this just because it appears it eventually gets under control by China's example, it's a completely different culture.

 

I keep telling ya's, keep up the Vit C daily, 500 to 1000mgs daily, you can't overdose on it, and what's it going to hurt?

In Australia with most jobs now being casual there is no sick pay, you either go to work sick or can't pay the rent. Can't pay the rent then it's out on the street with the other homeless people and ex-veterans. How Australia has progressed in the last 30 years.
