why are you using a ball pein hammer ? Really not made for driving nails only for blacksmiths in forge work and other metalworking
You can tell he has absolutely no idea what he is doing 😂 why you cloaking that hammer?
@mtechautomotive Sorry to bring up an older video. I found this very interesting and wondered if you were able to supply an update on how this finished up? Im trying to figure out something similiar for a 15hp project with my son. Great video
A& P and a Private pilot, Will most likely build of of these with my 3 boys :) Love the Video :) will definitely keep up with you
You say direct access to the stator winding? You mean the rotor winding? You'll get more power out of it by eliminating the diodes, changing to delta wiring and using 3 loads, one for each phase.
I’ve been thinking about building a dyno that generates power as a load instead of sucking it in as found in eddy brake dynos. I like your design. I think I’ll build a car sized version, anyone interested in such a project should subscribe.
what happened to the rest?
I used to get shouted at for holding a hammer like that 😂😂
My God is this for Comedy central or what. RED NOSE DAY ME THINKS
Any problems with causing brick issues with it exposed to the inside of greenhouse? Looking to do this on our east wall
Where can i find part 2
Can you please email me so I can ask a few questions specific to your build? My email address is on my youtube channel under the "about" tab. I am building a similar dyno here in Minnesota. Thanks
I see you’ve not chased in any flashing. Have you noticed any damp inside, or soaked timber?
What happened to part 2?
He gave up.
What happened to this build! I hope you haven't moved on. If you're having a hard time with something, you wouldn't be surprised to see many people will be eagerly standing by to offer advice in the form of "you did it WRONG and other harsh comments. Lol.
Were you ever able to get this thing running? Looks like a great design.
Thanlks, yes all running I need to do the part 2 video ijn due course!
@@mtechautomotive where did you get the shaft extension for the alternator input shaft? Is it threaded onto the alternator shaft? So cool, beautiful design.
Did it work
What prop is this ? Is this a standard prop that comes with the engine ?
PLEASE do part 2. I am especially interested
Where's part2
Thank you so much! This has helped me more than you know!
Part 2? I'm interested..
Really nice setup, trying to make something similar but heat water in an aquaponic system. Do you get a clean burn off the unit?
Very clean, zero smoke at all (I was concerned about neighbours etc)
You guys were partly responsible for me ordering my 12is empenage, you made it look so easy. Turns out you are a fricking engineer!!! 😁 I have sooo many questions. Do me a favour, could you drop a link for the grey primers please (avoiding all the debate on prime/no prime) I'm hoping to just copy you guys 👍
Haha welcome to the world of aircraft building also :) For primer I used rapid etch from a place called rainbow paints in the UK - I went with aerosol as was so much easier to work with - any rapid, fully etching primer will do though!
@@mtechautomotive I watched that video soo many times! Even looked up rainbow paints. Basically choose a company you can buys loads from at a reasonable price? My project folder has come from LAA, just looking for the right time to call the local inspector, I guess he/she will have a view. That joint sealer you used, think I'll pass on that step 🙄
any updates yet?
when you drill in brick, how will you make sure you are not drilling into water pipe, gas or electric cable?
This is the outside skiun, and im only going as deep as that one birck layer - we have all pipign etc inside the house on the inner skin. But yeah, always check!
Even with hearing aids, I can barely hear the person doing whatever he is doing and saying.
How did u measure the angles on the roof cuts?
Laying up and protractor :)
R.i.p. part 2
Can you make detal video about softer and hardwer
Excellent video!! Please do a part 2 this is very interesting! I plan to do a very similar setup this summer, but I thought of adding a brake rotor (as a weight) to the shaft of the alternator to be able to do pulls also (dynamic test) instead of only static.
Just to develop on my idea... I understand you wouldn't be able to measure the torque on the load cell with a dynamic test. This is what I would do to calculate power from RPM on a dynamic test: 1. First you perform a static test say at 2k RPM to measure the torque of the engine at that speed 2. Then, you perform a dynamic test and you only measure the rpm of the shaft, then you derivate to get acceleration. 3. Since you measured the torque at 2k rpm, and now you have acceleration, you can figure out the inertia of the whole shaft to calibrate it. 4. From now on you can directly correlate acceleration to torque/power :D
@@rantanplan1911 You could, however my plan was to hold and read every say 500 rpm automatsically to then generate the curve across the RPM range
PLEASE do part 2. I am especially interested in the wiring of the alternator. I've got the rest together
Hi Alex, did you ever get your dyno up and running? I have questions about how to wire the alternator also. Thanks
@@mikefries2146 Hi Mike. I'm not there yet. I will let you know. I am thinking of a 3-fase heating coil of a boiler, hook every winding to one fase of the alternator and apply current to the rotor for braking power.
any updates on this?
Hello take it easy
NICE! can't wait for " DIY Kart Engine Dyno ! Part 2" SUBSCRIBE ! , will you be sharing the arduino software " Open Source " ?
What the hell are you doing
my thoughts exactly
What a pointless video when theres no part 2
We l;ost the raw video files :( We will do an overview though!
Where is Part 2 and what did you do about rain falloff over your neighbours boundary?
Unfoirtuneatly we lost the video files :( But will do an overview of how to finish it off - we didnt close the roof right to the edge for the bounbdary :)
@@mtechautomotive thank you for taking the time to reply! I'm planning a project just like this one. This coming Summer. Hope it worked out well for you.
Great video and thanks for the information! Have been thinking of linking several alternators to try and achieve the same for slightly higher power! Good luck
Many alternators have zener diodes for rectification, clamping output to ~20, sometimes an external rectifier is needed. I have loaded a 10hp chainsaw to clutch slip with a 100A alternator, with basically the same setup you have here.
Interesting - there is definaetly a diode bank in this unit - can you explain more? I assume you removed the diodes and just went AC and higher voltages?
@@mtechautomotive I believe oem went with Zener diodes for the rectifier bank when cars went EFI, reason being that a failed “on” regulator could caused serious damage, I have seen 170V with mine open circuit, it would only hit 20V before I modded it, the zener diodes clamp/limits the max voltage across them as a safety measure. I had to fully disassemble my alternator to gain access to the diode bank, I cut the original diodes out and soldered three wires in their place, leading to a (cheap ebay) 150amp full bridge three phase rectifier, on a heatsink, then onto my load bank. Alternator was star wound, so 3x winding ends are connected inside the alternator. You could go to AC, but then you need to wire for three phases on your load bank, a pain in the proverbial, and can’t be done with a single element. What rpm range do you plan to test between? I’m running around 42 volts with bigger saws, so outputting 3x more power at the same amps than 14v Check my video for the rpm, volts and Watts on an alternator under ~6hp load, amps averaged around 75 through the run.
I have a few friends over your way, Im picking up my RV-10 tall and emp kit this month. Nice video, I was planning to do videos on my build as well like I do with my other hobbies. Cheers!
You can also use light bulbs to create load, easy to turn them on and off
becuase we can inject stator current, we can vary the load continuously and smoothly from 0-~4hp - we can use a PWM power supply to do this and software control it to also allow closed loop RPM holding :)
Standard light bulbs are not particularly suitable for this. Domestic automotive alternators are low voltage high current devices, as the voltage output will be less than the 110/220V higher wattage lamps are designed for, you need to use more than expected, example being a 1000w 220v halogen lamp draws only 2 amps at 60 volts, it will only consume 120 watts. Depending on the load you can expect 12 to 60 volts from an alternator loaded like this, 150+ with no electrical load. Just not night enough voltage for bulbs, air heaters etc when you need to dump a lot of electrical load.
@@motorsawing6739 We are using 12V heater elements as the load dumping
Hello, how is your progress coming along. You were getting close 5 months ago. Thinking seriously about taking the plunge on a 12iS. Thanks for any updates you can offer.
Once you have built one, all you need to do is repeat and sell it. Do it over and over again until you have it down pat.
Is there a part 2?
Yes, I was wondering the same thing?
@@myobs Yes sorry guys we lost the raw vid but will do a little overview video!
Wow if you are interested in an easy Dizzy spell... great video
Good progress! Go slowly and methodically and the harness will go in and make sense.
This is my next step. I've been putting it off.
Its aloit of hours, but its not "hard" if that makes sense :)
Thanks for all the good tips!
most welcome!
Hi Thanks for the videos, definitely inspired me to finally hit the button on ordering a kit. I was looking at a 7 but the 12is is more to my skill level. I have scoured the internet for shipping costs but cannot find any figures. Can you let me know how your kit was shipped to the U.K. and how much it costs?
