Some-Guy Posted January 27, 2007 Share Posted January 27, 2007 Just picked up the old 5 hp comp motor from the other and a bunch of steel for the frame so for the cost for this is ZERO. Iam going to build an adjustable power supply to control the alternator which I still have to get. all I need now is the leads ands iam ready to roll. going to go pickup a ton of extra steel right after I get off here just incase I decide to get fancy. Ill post some pics tomorow if I get any of it done. ohh if anyone has an adjustable power supply that can handle 0-17 volts dc with a 3-6 amp draw let me know! I dont really want to build one and I have been searching for a cheap used one but no luck. Ok Iam off ciao Mike, Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted January 28, 2007 Author Share Posted January 28, 2007 Had a scrap jetta towed away today and the guy gave me an alternator only a 60 amp one but it will work fine 32-40 volts at 40-60 amps is enough for now. I just spent an hour and 20 minutes boring the taper lock coupling to fit the shaft its a weird size .669" the taper lock was .626" and it took a damn long time hand feeding and only being able to take a .003" per side cut! now the taper lock is .671 and fits nicely not sure of the hold since it doesnt really get alot of grip on the shaft only about 3/8 engagement I might take it back tomorow and get an aluminum pulley and bolt it on with lock washers we'll see how this works first. Pics tomorow once I start assembly. oh yea I forgot I built a 0-17 volt power supply but it will only handle a 1-1 1/4 amp draw not sure if it will even hold up guess we'll find out!

Some-Guy Posted January 30, 2007 Author Share Posted January 30, 2007 Ok Picked up an aluminum pulley rebored it took the other one back And The alt spins at 6576 rpm now the pulley was a SUPER cheap casting i Could only get it to run within about .025!! its got a bit of a wobble but its working. The next problem is that the power supply DIED it cant hanlde the load and the output drops to 3 volts and it starts smoking alot lol. and I can get strike an arc really easy now since I just hooked it up to a battery but I know why they say use atleast a 90amp alternator this one is much to weak there is no penatration I can only run surface beads and since the arc is so weak You can easily get the stick stuck. Once I find a new alt Ill build a proper cage and figure out how to get a headlight dimer working as a way of voltage regulation . . . its on hold till that happens.
