I think that all of us we miss Mayhugh1´s posts and builds. The finish level and detail of the explanations are so great that I consume every word on them.
@mayhugh1 Are you planning to start a new build?....you have all of us waiting.
My suggestion is to check the Grizzly catalogue for the same model (As you know, most of the imported lathes are sold under a number of different brands). Usually, Grizzly has super nice, detailed manuals for their products, and they are available online.
I fully agree, If I put the effort it takes, I would make it as closer as the real Merlin as my capabilities allow me. Where did you get this picture? Is it a modified Olsryd? Is there any available plans?
Hi Petertha. From my old days in the RC Car racing scene, I have several carburettors, most of them seem to be better made than the standard Perry. This is a carburettor from a Sirio 1/8 on-road engine.
Thank you both for the inputs!! I think I'll visit my hobby store to buy a good starter based on Steve's advice. I thini I'm too lazy for designing and machining a new prop hub to use Cwelkie's approach, although I'll consider it seriously for my next project
I've just finished my Edwards 5 radial build (pictures soon). I've still have not done its firtst start and now I'm debating myself on the best way to do it.
With the prop installed it takes some effort to turn it by hand due to the amount of compression....it does, but not as...
In your own words..."5000maH capacity rated at 20C yields 100A. That's C-continuous so 8-10A wont even tickle it. At a load of 2v * 10A = 20 watt-hr, this pack would yield 1.8 hrs continuous running ".....Not correct
I don´t have to google this, being an electrical engineer for more than 20...
Your train of thoughts is not correct. The C rating is the peak in Amps that the battery is able to deliver. The capacity in this case is 5000mAh or 5Ah, it means that it has enough stored energy for delivering 5 Amps for an hour, 10 Amps for 0.5 hours or 2.5 Amps for 2 hours.
I machine my valves outnof 316ss in a manual lathe. Before making the valves, I make the valve guides reaming the inner bore, then I machine the valves leaving them 0.03 mm oversize in diameter to allow for lapping them to get a perfect fit on the guides. Very important to check consistency in...
Easy solution, I like simple solutions when possible, my only concern is blowing some plugs at 2volts. As far as I know, they are happy with voltages from 1.2 to 1.5v. How's your experience in that matter?
Close to finish the project and now I'm debating myself between different options when thinking about the glowplug driver. What do you use? Arduino to regulate depending on rpm's, NE555 timer to provide an adjustable output, a voltage regulator to provide a constant voltage? I'm a little bit...
Now that my Edwards radial 5 build is close to end, I have been playing with the idea of starting a Merlin as a next complex project and I am considering the options.
While fiddling around the Internet I´ve found what it seems to be a very comprehensive set of plans by K.E. Olsryd...
Have you watched Clough42's series of videos on building a grinder that fits an Aloris style post? I made myself one and it works like a charm. Anyway, having a surface grinder, next project will be a cylindrical grinding attachment.
I've been working in the plans of this engine for some time. Currently I am analyzing the Kugelfischer mechanical injection to check if something can be done in the model, although it seems to be extremely complex. If anyone is interested, we can make this as a group project. Currently I am...
Thank you one more time!! I´m very proud of this community. In such an activity as engine making, you´ll need technical support sooner or later and this forum is full of people like you willing to do it.
Just one more question: Must the diameter of the follower to have a certain proportin in relation to the grinding wheel diameter? Thank you very much.
I am unable to find the Strictly IC number you mention.
