Yeah i will come back to it but I am not sure when.

@makeorbreak2798 I'll not the smartest guy, but if you need some help with the dyno, I'll could maybe help you.

Thank you I did finish it but the drive shaft kept breaking i need to redesign the drive shaft. i have been restoring a car which has taken all my time. 👍

That will be the way i think

Thank you 🙏

Yes it’s very much the same, depending on power you would probably have pockets on both sides of the rotor

Hey mate its a cnc6040 router, but I rebuilt the gantry with linear rails

Sorry mate it was off the top of my head, cnc ran the shape but then i machined everything on the lathe, the pockets are very easy to do on f360

Kept breaking the drive shaft so i need to redesign it its an easy fix but the vibrations twist the drivesahaft and would glow red hot, so the dyno got pushed aside i will come back to it soon 👍👍

Thank you 🙏 I appreciate the kind words

Sorry mate its been put on hold, it will happen just not sure when 👍👍

Just oil seals but I removed the springs for a bit less drag

Its on hold man, i had it running but it kept snapping drive shafts, i will come back to it before too long. 👍

I did just see one the other week and yep they are fairly similar

Thank you man, i am not sure yet it has been on hold but i expect it to hold 20hp, it is all up and running but the drive shaft keeps snapping so i need to redesign that, the vibrations are a problem

@@makeorbreak2798 bugger! Which shaft is breaking? The coupling or the water brake itself? Do you run a clutch on the engibes you are testing or just direct drive?

@@dancarrigy6598 the shaft between the couplings it’s designed to break but snaps almost instantly, its direct drive no clutch

@@makeorbreak2798 could it be to much preliminary load? (Try it dry maybe?)

Actually, do you have the sae paper on calculating the hp it can handle? I purchased it this week, its a bit of a read! But your design might be more efficient than you think. What rpm do these engines get to?

Thank you

Its a walbro wyk-33 copy you can find them on alliexpress under 49cc carb But they vary a bit between different sellers

Hey mate I’m just using 6061

@@makeorbreak2798 Thanks, I'm building but I don't know if I can do it like you.

@@ฉัตรชัยอุนาศรี33 awesome mate good luck i need to get back into it i have had a long break from it

Hey man its a dubro prop balancer

Thank you sir I appreciate your work 👍👍

Awesome these aircooled engines run extremely hot it seems this one hasn’t seized (luckily) and been well over 200c, I normally relieve the top outer diameter as well.

Yes mate the piston is good i had it too lean and it was well over 200c, its still good i have that engine apart and just been looking at the piston

Yep i use fusion 360 to draw what i want the piston to look like and then create the tool path, from there you send the code to your control software (i use mach 3) and that controls the router, but first you need to design or copy the holder i that i made, its a lot of mucking around but once done its repeatable.

You could be right mate, i am interested to know myself, i am more concerned about the pulse and not having smooth flow. Thank you 🙏 👍

@@makeorbreak2798 on certain brand dynos, they use a oversize pump and use a regulator to ensure consistent volume.

@@CMillet86 thats a great idea i was thinking about a bypass valve to keep the pump running, i might run 2 pumps and reg 👍👍

@@makeorbreak2798 A great piece of work!! A true thing to be proud of! For the pump youre using, you will be faced with two working points. The increasing pressure and the higher volumeflow. Both will end up in a exponential curve and will be tough to regulate. But worth a test!! I would also test a fuelpump with water, delivering high pressure and high volumeflow plus a 3 port valve to keep the pressure constant.

@@GlobalFlyer thank you 🙏 yes i think you are right on with that, I considered a second pump which might be ok and also with a regulator inline to keep the pumps running and at a constant pressure. Thank you

Thank you 👍

Thank you 👍

Thank you 🙏

Thank you 🙏, it is an upgraded chinese cnc6040 router 👍

Thank you

Thank you man, I don’t have one but i might have to get my hands on one 👍👍

Thank you pal 👍

Yep you can get sealed bearings and they do work some even come with sealed bearings But they leak more than the rubber seals do, i guess its just personal preference

@@makeorbreak2798 ok thanks, I appreciate you and your channel honestly it's hard for me to find small motor specific info. Will the band seals outlive the motor or is it a maintenance issue I'd be willing to trade a little power for? Thanks either way man you've done a whole lot for the small bore homies for sure

@@Najsnwjsbdn thank you mate I appreciate that, the seals without the tension spring last a long time and will probably last as long as the motor would

Hey mate thank you I appreciate the kind words, yes i will be porting and modding these check out some of my first videos on the ported 30.5cc, i will dyno these motors stock and ported with various pipes 👍👍

Ohr thanks mate, a stock g290 will be tested for sure 👍👍

Thank you 👍👍

Thank you 🙏 i have the spindle at about 11k rpm with 1000mm/min feedrate, i always run a finishing pass with a 1mm step over and .2mm depth cut the reason for that is I don’t have any chip evacuation at the moment so until i do then it could maybe do a .3 or .4 depth cut. my machine is half way through its upgrade 👍👍

@@makeorbreak2798 that is great info for me to start with thank you very much, and hurry up with part 3.

@@rct2 😂👍

Thank you 🙏 i designed the waterbrake, it is inspired by every waterbrake i could find pictures and videos of online😊👍

Are willing to share some cad drawing. I'm interested in your design and would modify and enlarge to work with 4 stroke Briggs and Stratton Engines around 10-15 hp. thanks for your video and great work on your design... :)

@@smaggies Im also interested. But to use the water brake for generating hot water from a water turbine and a small stream next to my house :-)
