I thought i'd already posted these test result from a few days ago... On the advice of a previous post on this thread, I have just load tested the generator on a small lathe that is fitted with a digital rpm indicator. At 460 rpm it produces about 13 volts, which is what I was after. I had a...

An alternator need to be turn at about 2000rpm + to start to develop a current, so it would have to be geared up via a chain or belt etc, which introduces loss's that I can't afford.

In the next few weeks (or more - as the boiler I plan on using is out of commission at atm) I'll couple the generator to a 2 1/4 x 2 3/8" steam engine I have, and give it a test run, the engine is considerably bigger than the 1 1/2 x 1 1/2" engine i plan on driving the generator with, but it...

Thanks for the info, I'm thinking that i will use a basic regulator to start with and at a later date get a high tech regulator like this one... http://secure.oatleyelectronics.com//product_info.php?cPath=21&products_id=832 ..which the Tech guy I recommended it to me yesterday, & he goes...

Hi There, I have been away working out west in a remote location and haven't been able to access to the internet, so its time to catch up. Thanks for all the advise and info, its much appreciated, up to the last reply i made, I came to the conclusion that I had several options, to use a...

Hi Tel, I just got a reply to my email from Chronos about these tool holders... Small Diameter Turning Tool SDTT for Myford Lathes - SORRY OUT OF STOCK (Ref: XC10....) [email protected] Hi Many thanks for the email Yes they are on order with the factory Mark

Hi Tom, After what I have learnt here...I'm thinking I'd use a standard car regulator, and a brushed DC motor. I wasn't expecting to need 1/2 HP for 100 watt's, I was hoping for 3/8 to 1/4 HP or less? my calc's are as follow's (correct me if I'm wrong)... (1 1/2" x 1/1/2" single...

Hi Ed, I looked at what is labelled as a Suzuki Seira here in Oz (small 4WD) and it had a 20 amp alternator which was about 4" dia x 4" long and could be disguised with a dummy cover to look like a generator. What put me off was the 20amp output-too high, and it would have to be geared up +...

Thanks for the advise Albertorc19, I don't know a lot about electricity generation. I'll go with the regulator. I'd be keen to see the results that you get:). Martin

Hi There, Thanks for the welcome. The whole forum seems like a friendly & helpful group. My main interest is in large models/full size steam engines. I currently have a home built 2 1/4" x 2 3/8" single cylinder steam engine, which looks a bit "agricultural":eek:, that I plan on putting in a...

I've already posted my first question, and missed this. I'm into anything in steam. I'm about to buy my own lathe & there are a couple of steam engines I'd like to make. Its a great site & some of the machining that has been done on here is amazing & I'm sure I'll learn lots. Martin

Hi Cogsy, It'll attack you. You need to use a travelling steady, with a little bit of grease on the steady guides. and a v small radius tool (minimal contact area of the tool on the job), fine cut's with a slow feed:)

Thanks for the advise above...:) I don't know anything when it comes to power generation. To clarify a few things, the motor needs to be.. - rated at 3 times the power (watt's) I would like to generate. - a permanent magnet motor is best. - turned at the same "powered motor rpm" to get the...

Maybe grind the side off of a hacksaw blade, until it'll fit through the split in the die...hacksaw blades are cheaper than slitting saws:) As for your second question, I have a heavy engineering background and wouldn't have a clue, I'll leave it up to the experienced fella's here.

The easiest way to cut the grooves might be to grind a piece of High Speed Steel to 3mm radius (and turn the job slowly)

I'm low getting back to you Machine Tom... I might be wrong, are talking about a voltage regulator?

Thanks Albertorc19.. I'm a fitter/machinist & I don't know a lot about electricity..if you don't mind..a couple of questions... From what your saying...do you have any idea how efficient it would be? If the rpm of the motor is say 3000rpm, would it generate full current at 400rpm? or do I...

Hi there, I'd like to use a Steam engine to drive an electric motor to generate power:). Ideally I'd like 13/14v (to charge a battery) and 6 to 8 amps @ about 400 rpm. What I have learnt online, a permanent magnet electric motor is the way to go. What size motor should I be looking...
