Building my mill...

[Kbeitz]

Well I got my brush coat all done...
The spray coat wont be so bad.
Then comes the electrical.
This is what I got so far and this is showing for only one drive motor.
I got two drive motors the log lifter and the log turner to draw in yet.
Also the master switch and fuses.

You're a better man than me.  I look at the diagrams you post and my eyes glass over and a little bit of dribble escapes from the corner of my mouth and slowly runs down my chin, through my beard and into my lap.  My wife finds me hours later and screams, "Are you having a seizure?!?"  I snap out of it and tell her, "No, there's a guy on the forum that's building a sawmill."  She then looks at me as if I'm crazy and quietly leaves, shaking her head and muttering something about sawmills and cookies.

It helps when you like playing with electricity.
I'm hopeing I got everything right.
I cost money when you goof up.

[Ox]

Yes, having an interest definitely helps a lot.
Roger that, loud and clear, on costing $ when mistakes are made.  I wish you all the luck.

I installed my solar system, built 2 wind turbines, built a charge controller from a kit.  Seperated most of my house to a box run by solar.  Put a preheat hotwater tank run with excess solar based on the battery voltage.  With all that, You are so far above my skill level that I get dizzy when I look up to where you are.  I do apretiate the costly mistake aspect.  I look at your post and want to help, think to myself I should be able to help and then relize,  I don't have enough skill to help you.
good luck

gww - you did all that and in other posts you call yourself stupid or not smart enough!  I beg to differ.

Credit where it's due, my friend.

All I can say is doing house electric is mostly carpentry but curcuits and controlls are a differrent animal compleetly.  I do know of a couple of forums where there are truely smart people and not just copy cats like me.  They know why something is put where.  Me I ask them and then just put it there.  I don't ever figure out why I put it there.  The only smarts I have is knowing who to ask and who to listen to.  Besides that.  You haven't seen my stuff so I might still be dumb.  I haven't killed myself yet though, knock on wood.

If you ever want to run your circuitry by smart poeple I do know a couple of forum sites.  They are mostly for solar but you pictures would be understood by them and they are credable helpers.

Hi Kbeitz
Ive got a circuit drawn up for you but my computer wont scan it but hope to have it sent by the end of the night. The speed controller you have gets its reference from the wiper lead of either a 1 k or 10 k pot and also has another 2 leads that close when the pot is in the off position to keep the drive from going to run mode when the pot is almost turned to off position. After looking at several small dc drives manuals they all suggest leaving power on the drive and starting the motor by the pot input and also shorting the pot input to the negative pot lead so that there is a 0 volt speed reference. On mine I used one power relay for direction control, an AB 700 relay 4 pole with reversible NO NC contacts. If the direction relay was not energized then it went fwd if energized then it went reverse. I will try to post the diagram, it will make a lot better easier to understand.

The drawing assumes that the A terminal of the pot is the common voltage or 0 volt side of the pot and C is the + voltage side of the pot, typically 10V. So when stopped the wiper signal will be 0 volt, when running not fast it will see 2v, when running and fast relay is energized it will see 8v. You will have to verify this before connecting the motor to the load. Good luck.

I started the wireing today. I made it move under power just to see how it would work.
First thing I learned is that it does not need the electric brakes.
Thats one thing less I will need to wire up.

[Ox]

Good news!  Less is more in this case, right?  ;)

Well today 5/14/15 it's finished.... I am so tired of working on this project. Next week I'm takeing a day and going for a cycle ride...

I am impressed.  Now what?

[Kbeitz]

Couple of neat things I added. So many people talk about sawing into the log dogs.
I put a bar on the head that will ether push the dog down or stop the mill before the blade hits.
See first picture. Then I added spring loaded stops so I can flip a switch to return the mill head
back to the starting spot at full speed. The spring loaded stop hits the limit switch and retracts as
the mill is coming to a stop. There is a secondary limit switch just in case the first one fails.

The two electrical boxes had some changes....

Take a break and let the paint dry...

[mesquite buckeye]

Very cool. ;D When do we get to see some sawdust? 8) 8) 8)

Hoping next week....

Heck if I had made that I would have to get sawdust ALLL over it and me right NOW.  :D

With the sticky paint the sawdust would be forever....
Think I'll wait....

[justallan1]

Looks to be a real nice job. I know i'd be chomping at the bit waiting for that paint dry.

[Magicman]

That is a nice job and well done.  The R & R is deserved.   8)

[Ox]

It's clear you put a lot of thought and time into this mill.  You should be very proud!

[Kbeitz]

I took the mill for a ride today...
Handled real good...
I also stopped in at the junkyard and had it weighed ... 2340 lbs.
