SX3’s Ciao perso [English]

Love those toys 🙂

Why don’t you use the coolant of the machine?
One of the benefits of cnc is the ridiculous ammount of coolant you can use.

@Lastpak, thanks 🙂 yes, a pictures tells more than a thousands of words, thought someone else might find inspiration or improvements aswell whilke thinking of making a “zelbouw zij inlaat” or how you spell it 😀

@AAT, Yes, the automatic coolant looks kind of ridiculous and gets a bit messy.. It’s very convinient when doing a larger job and don’t want to stand and stare at the piece while the machine works.
In this case, the only reason the automatic coolant wasn’t activated was because the machine was empty on coolant liquid and it was getting late, so I just sprayed manual with the only 100ml T-red, red alcohol I had left.

Sounds very familiar.
Just like I used to do it at my former employer 😉 (although that was conventional).

very nice work!!!

Thanks! 🙂

I will need to buy myself a new crankshaft, I sold my malossi RV case complete with crank, should have kept the crank-shaft =/ But I’m not sure which to get, either the malossi, or a “normal” crank.

The malossi if fully round, which in theory should give higher crankcase compression, but practicly, will it actually give me more power or is throwing money away by paying 180€ for a crank?

I’ve seen that JMPB have a couple of different cranks P10, starting at 55€.. are they poor quality? Any recommendations from you guys? =)

Hello,

This thread have been resting for a while.. I’m thinking of selling the project, due lack of time.
I put the motor on the table yesterday, started designing a fan for it, thought it will be easier to sell if it have some sort of cooling 😀

Anyway, I don’t have any original Ciao motor, so I can’t take any measurments, so I need your help guys! 🙂

On the flywheel side of motor, there are 3 fixation point for the bolts that connects the motor to the frame.
If you put a ruler/heerser between the points over the flywheel, how large is the gap between the ruler/heerser and the most top position of the flywheel?
Is there any gap? Is it flush or does the flywheel protrude?

Thanks in advance 🙂

The reson I ask about the level, on the HPI rotor, there is a Hexagon that sticks up, that hexagon is completly flush with the 3 mounting holes that attaches the motor to the frame.. inside the hexagon it’s 4mm deep, thinking if this point is the same height as the original vliegwiel ring or if the top of the hexagon is the same reference point. 🙂

[sx3-sweTopic starterBerichten: 290]

I just realized I have to re-machine a little.. I followed the HPI instructions and milled down 2mm below center ring, but now that I fit the parts I realize a couple of things

The rotor rest on the stator mounting bracket, doesn’t all the way down on the crank.

So, what I have to do is to do is:
1: Mill down fixing points on carter/crank case, to lower the bracket.
2: Put the mounting bracket in the lathe and make the inner diameter larger, because I don’t want to mill in the cooling line for the bearing. Will make it possible for me to lower the bracket even more

As you can see from the pictures, the above of stator iron is in line with above line of magnet, there iss 7mm marginal to the lower end, so I’ll do my best to lower the stator as much as possible, to free up space for a fan that can circulate above the stator.

Depending on how much I can lower the stator, I maybe will put the rotor in the lathe and take off 1-2mm from the top, to make even more room for a fan.. 🙂

Also I tooked the selettra rotor and compared to the HPI, the selettra have small fins on the underside of if, I don’t think it will do much for cooling, other than the crank case, and thats not where the actual heat is.. maybe if I find time I will put the HPI rotor in the CNC make small fins also, not that it will help, but mostly for placebo 😀

Note to myself regarding the stock settings of the PHBG 21mm CS:

– 262 AU
– 90 main jet
– 50 middle jet
– 60 bottom jet

I think I will find some time next week to machine the HPI parts (hopefully) then I will start CAD the fan and then finally mill a mockup.. also thinking about 3D printing a fan maybe, to keep the weight down.. (biggest reason for inner rotor is the wheight savings, hence reving faster)

[De BrandweerBijdragerBerichten: 571]

Nice to look at! You are still willing to sell it?

[sx3-sweTopic starterBerichten: 290]

@De Brandweer, I will consider it, but I want a working fan for it first 🙂

Anyway, I took my time yesterday to mod the carter + ignition..

1. I put the adaptor plate for the stator and put it in the lathe and reduced the inner diameter so it matches ut with the stator inner diameter. Because I will need to clear the cooling lines in the carter for the bearing.

2. According to the HPI manual you should mill the 4 fixation points of carter -2mm from center ring, yesterday I took away another -5mm, so now it’s -7mm in total!

3. I removed the stator from the aluminium bracket and put it in the lathe and lowered the stator 5mm. I had to make a cutout in the bracket, so that the red pickup can fit 🙂

Basicly I managed to lower the stator 10mm from my earlier pictures which is really great 🙂
As for now I have 4mm from ciao frame to top of rotor and I have 4mm from top of rotor to highest point of the stator (The pickup.

What is left to be done!
I have a few options here and I’m not fully determined which route to go!

1. Put the rotor in the lathe and reduce 2mm from the underside, then recone the rotor. This will get me a more optimal match of magnet/stator. Then build a 4mm thick fan which will have 2mm clearence to stator/ciao frame.

2. Put the rotor in the lathe and reduce 2mm from the TOP of the rotor, build a 4mm fan and have 2mm clearence to both stator and frame.

3. Draw a fan in CAD, and make a mockup, probably will 3D print the mockup and see how it fits, make som minor adjustments, then redraw it and either CNC mill from aluminium or 3D-print one, but I’m not sure about the heat though!

Here is the version 1 of my cadded fan.. It should fit inside the carter and frame 🙂

[Wilk1985ModeratorBerichten: 3729]

Very interesting! I am curious to see how this will run. Would be great if the fan would fit..

[sx3-sweTopic starterBerichten: 290]

Well, I’m curious to 😀 I think it will run quite good, if not atleast it’s unique 😀
So my engineers have looked at my fan, and due i the circumstances, it wont get much better than this.. I will 3D print a mockup as soon as I find time to visit my friend!

Anyway, I made an EVO-2 of the fan, it means it’s 3D solid, te first one were just wireframe, or what to call it.. And I added some holes to fasten it, and also for adjusting the timing, while everything still is mounted.. 🙂

As some of yu have contributed me with knowlage, I will release the CAD file for the fan, as soon as I confirmed it will fit. 🙂
So that anyone that wants, can make their own fan.
