Homebrew Is A Brewin

Thanks for the suggestion but it's already part of the plan . ;D

Thanks for the tips everyone. I used pipe clamps to square up my rails and plywood used as spacers. Not too tight or the plywood would bow and throw everything off. I started with just the 2 rails. Squared both to themselves. Everything else is square to them. I used fan to help cool it off quicker. It blow air across the top and not directly on it.



There is my Forewoman inspecting my work. By the expression she is giving me, ??????????


I have a Tecumseh 11HP sport engine (go-kart). It has an electric start and dual alternator. Green wire has 11Volts at idle and Wide Open Throttle. Red wire has 9V at idle and Increases Voltage with engine speed to 25V at WOT. Can anyone help with connecting to battery with voltage regulator?
Thanks again for everyones help and input!

Looks like progress is being made..  8)

I was trying to manipulate some bending steel myself today, with clamps and welds...  ;D

Sounds like that red wire would go to an external voltage regulator then the battery. 11 volts from the green wire is odd. It may be the charge wire but should be 13.5vdc

The green wire may have a diode in it that drops the voltage just a tad.  I ran into that on an old international tractor once.

Looks good guys.

I am confused about dual alternators. Why?   11 volts seems like it is a little low for charging and for sure 25 is too high.   If this is coming straight off the windings, the are you checking a.c. volts?  I'd try to locate a schematic from the manufacture.

This is the engine I have, except I dont have the yellow wire.

Well that splains the low voltage at the green wire. It is grounded to shut the engine off. : The red wire would need to be hooked to an external voltage regulator. I suspect you will find that yellow wire hooked to the B post on the starter solenoid. It will come from a diode or or more likely a voltage regulator on the engine.

Thanks for the welding link, GrappleT

Looks like you're coming right along good on your mill

Thanks and your welcome . Hey how'd ya like the rain at the expo, I was there Saturday afternoon and it was not nice .

Update from post # 51

I have been looking for a voltage regulator. Maybe automotive type, nope because I can't find pin-outs. I happen to come across the illustrated parts diagram with the VR. Huuummmm?! Let's take the flywheel shield off and take a look. What did I find in there??????  Red is from internal voltage regulator. But 25 volts? Maybe i'll hook up battery to it tomorrow and check it then. It might be full-fielding. Trying to charge with no battery. BTW, Green wire is for remote shut off button. Really wish I had manual from the shop that sold it to me.

Well, It's been awhile, and I've been working away and here are the pics. I need to come up with a different type of wheel for the carriage to roll on the tracks. I'm a little out of square. When the cutter head gets about 10-12 inches from the top it binds on guides. Gonna try it out tomorrow on some scrap logs. My wife said she would watch from the house with her finger on the 9-1-1 button, just in case. Still have to make the guards and maybe paint. This thing is HEAVY! I don't see how I'm every going to make it portable.

This is a great group of folks with varying opinions. Please weight in with all you got. Good or bad!!!

[jrokusek]

I like your blade guides.  Did you buy them or did you turn them yourself?

It's funny.....when my dad and I were debating where to place my homebuilt sawmill my wife piped up too and yelled, "NEXT TO THE HOSPITAL!"

Jim,
My brother-in-law made them for me.

Well, it cuts! Pretty good too. I need to get a v-belt because it's starting to wear and it squeals on throttle up. Most importantly I figure why there are log dogs on sawmills. Wow! Anyhow, my wife and Mother-in-law were having a fit because I was going to run it without  the guards. I told my wife " Don't worry. If there's an accident. you'll be a millionaire" She didn't find the humor in it.
