Scratch Build – In Progress Ringo's la ultima [11-03-07 update]

I am truly amazed. Beautiful work.

 

Whoow!
This is some serious plexi skills! And those reservoirs looks amazing!
Looking farward to follow this thred!

 

Thanks a lot for the great response.

Today I milled the acrylic tube, that means that I cut 13mm off. I approximated the time to do it on 2h. I was very suprice suprised that I only ned 1.25h to do this. The next step will be the grinding of the cutted surface.

Here are some pictures, who I made.



The last figure indicates the cracked area.

 

Pure awesomeness!!! I'm getting definite "Tribal-vibes"! 8)¨

Keep up the excellent work!!!

 

You know, I was looking through and thinking, "Is that thing going to spin in the water?"

Then I thought, "It looks like it's going to spin, cool"

Then I watched the video and now think, "Holy Crap, that's amazing!"

Props to you, that's crazy!

 

Thanks, yes both rotores should spin in the water, if it is done, it schould rotate in oposite directions. With a single rotor works fine while the testings. The main problem is do get both bearing exactly upon each other. If both are aligned the rotor works very well, it will work with a little pump. The pump pumped round about 300l/h, the pressure head is 0.6m. The aligenment of the bearing will be a problem, but I think i can managed it.

The first idea was. The water should flows throug the acrylic wings. I can't realise that, because I couldn't drill a 1.5mm hole in a 3mm acrylic. I have try it, but the only resoult was, broken drills. So I changed the concept to tubed outlets. And now I think that was the right decision.

 

Hello together,

the first part of the update is the grinding of the acrylic. After the cutting i milled the surface, I milled 1mm off, but that was a bit to much risk. I decided to grind the rest. After the milling I had one crack inside the acrylic, that crack was the old one from the bonding. The crack was 1mm deep. First I used a 180grit Sandpaper. Then i changed the sandpaper to a 400grit. The last one, who I used was a 2000grit. I allways grinding wet, because the results of the grinding are much better.
Now I will show you some pictures.
Some Pictures of the used sandpaper.



Next a figure which illustrates the post modern grinding machine


The last one shows the grinded acrylic.


The other part is the modification of a air relief valve.
The problem was that i don't have a 1/2" thread drill. I only have a 1/4" thread drill
My Dad had the idea to bonding a 1/4" fitting end on the turned end of the air relief vavle. So I had to turned the 1/2" threaded end on diameter of 7,5mm, that was the inside diameter of the fitting. After I turned the 1/2" end I turned to notches in the end surface. The inner notch is for the 1/4" fitting

I decided to use a sealing, so I have to make a second notch. For this notch I used a selfmade truning chisel. I rounded the egdes. I have made this chisel for the sealings in the friction bearings.



After the turning I have to bonding the two parts together.



The finished part air relief vavle. Only the top part of the valve is missing.


I hope you will understand my english explanations.

 

You made your own release valve? AWESOME!!!

 

I think it's better to say. I mod one. Here is a picture of the original


This valve has a 1/2" thread, but I only have a 1/4" thread drill.

 

exactly what i was thinking

 

Hello together,

today I startet the drilling work on the acrylic tube. I have to drill 3.7mm holes in 5mm thick edge of the acrylic.
I used the mill to do this job. First i mark the positions with a 3.3mm drill, which I use to drill the mounting holes in the bottom and top plate.



After that I changed the drill, I have to use a 3.7mm drill for the brass mounting inserts.
There wasn't much space for mistakes.



The next two pictures showing the holes on one side. The depth of the holes ist 4mm.



Tomorrow I will drill the second side of the acrylic tube.

 

Really nice drilling, so precise.

 

Impressive work, I would have broken the acrylic tube by now.

 

Haha I hear ya, it really looks scarily close those drilled holes. But I guess if you take it slow and just have patience, you'll get what you want.

Keep it up, it really is starting to look good already.

 

wow... thats precise.. great work mate

 

Thanks for the good feedback.

Today I start a new part. It is a mounting part for the release valve. I wont cut a 1/4" thread in the acrylic, so I decided to make a mounting. First of all I sketch the part in cad, then I make a quick drawing, with the most important measurement.



Then I start turning. I used a round aluminium with a diameter of 55mm.

Then I drill the hole for the thread.

Then i turned the inside and outside shape.


In the next picture you can see one of my favorite chisels ( it's a self grinded chisel)


Before off cutting

The off cutted part, tomorrow I will finish this part. I have to drill some holes and I had to trun a noutch for a sealing on the backside.



The other part, who I start to build yersterday was a mounting clamp for my 8x8 mm chisels. The old clamp, which is made out of aluminium is at the end of life, so I have to make a new one. The problem on the old one are the threads vor the clamping screws.
The next two figures shows the milling and the end milled part.

 

Beautiful machining.

 

This is looking great! I love some heavy duty plexiglas fabrication.... and some seriously good machining!
great job, can't wait to see it develop.
subbed

I too would have probably broken it many times and stomped it to pieces by now!

 

holy cr*p this work is amazing... complete custom fabrication rocks!! can we have your address to rob the finished product

 

wow boy are you good
