Dynamo build by castings

[rhitee93]

Manfred, that is a beautiful design. I would be in for a 1 or 2 sets of castings if a batch ever gets made.

Thanks for sharing your build with us

I would be interested in a set of casting depending on what it would cost. Would make an excellent addition to any engine project. What is the designed operating speed, RPM?

Hey Don,
I have in minde to place the pattern in the foundry and any one can make his one order. A other way is to set up a Team Project and make a bulk order to the foundry to get a better price.

I am in for a set or two of casting, but it would be cheaper if other members would request some.

I'm also in for a set or 2 of the castings.

I can't help but think that it would be more economical to have a batch of casting made and sent across the ocean than a bunch of individual orders. I don't suppose anyone in North America, with deeper pockets than mine, would be willing to get a quote from the foundry for enough sets of castings to satisfy the short term need. I'd be willing to put up the money in advance for whatever I decided to buy.

Manfred, thanks again for sharing your design with the rest of us. I really like the styling of your generator and hope to build one

great job, I would also be interested in a set of castings.

Hello Brian,

I think one of you should make list with the names and how many sets. Than you shoud ask the price for one set. Than you should find out the price for all sets to get a discount.
I have payed for one set € 150,--
The weight of one set ist about 3 Kg and the shipping price by post is
€ 36,-- that I have found out. The € goes down, so the time works for you.

Best Regards
Manfred

All,

I have sent an email to Mr. Hansmann asking about the cost of 10 sets of parts shipped to the USA. I'll report back with the response.

I really don't want to be the front man for this, but if there is enough interest maybe we can find a way to pool our funds and do a group buy.

 

[ChrisLister]

We could place an group order and let sent them a package to the States and a package to somewhere in Europe?

I could do the Europe package.

And send them from here to the individual addresses.

Greetings,

Chris

HELP

is there some one around to sell or build smal instruments DC voltage and DC Amp in the old fashion look. I dont know how to due that.

Best Regards
Manfred

 

[Don1966]

Manfred I know of no one who makes mini meters. Iwish I could help you.

Brian have you received a quote on the casting set?

Manfred, Great piece of craftmanship, very good looking. larry

If its any help, try fleabay, a mate of mine recently purchased
some new bakelite imitation gauges from asia somewhere.
cant contact him at the moment.
An ebay search should turn them up.

Magnificent piece of work there to Manfred

Hello Dave,

I have a ebay order runnig with a round DC voltage and amp meter. But they are still to large, may be I can modify this instruments.
I think that is a hobby business for a man can due that. No stuff like that is on the market.
I`m working on a rotor modification to get better results. The electrical parts to change from AC to DC is an open order too.
A baseplate from wood is also almost finished.

Best Regards
Manfred

Manfred,
Back in the 70's and 80's it was fashionable to have "VU" meters on the front of your stereo. These were very small d'arsonval meters, and the movement could probably be transplanted into a proper scale homemade case that looked old. If you could find a couple of old junk stereos, the rest would be doable. I can help you calculate the right shunt resistor values to make the modified meters read to the right scale.

Don, I haven't heard anything back about the casting yet. Maybe I should find an intern at work that speaks German and try again in their language.

 

[Don1966]

Good idea Brin the VU meters would do. They all work on 0-1 MA or 0-50 micro amps.

Don

Hello,

the final rotor construction is found. Compared to the polyurethan rotor there is a voltage increas. The inside coil from 20V to 22,5V AC and the outside from 22,5V to 26,3V AC at 1000 rpm with out load. The final test with load a.s.o. I`m going to due if the DC stuff is installed.
The gap between the magnets are filled with resin.

Best Regards
Manfred

You can throw my name into the pot also. It would look great with the steam twin cylinder rope driven flywheel that I have sitting on the back burner.

Larry, this rumor is going round and round in my head, a 2 zylinder belt drive or a 1 zylinder direct conected. I wait for the outcomming DC voltage to make a decision on that subject.
If I can get a 12 segment komutator than I`m going to build a DC generator in the same size.
Best Regards
Manfred
