Arnold, it's perfectly normal to mess up a blade or 2 (or 3 or 4). Don't trash them, first time you come this way, bring them. You might be surprised what I can fix. Maybe we can arrange a visit to CaseyK, he's about 30 minutes from me. Been trying to do that for some time, he works a 4 week on/4 week off day job off shore. Seems like every time he's home, I'm snowed under with some hurry-up project.

Arnold, very impressive sawmill build indeed.  Takes an impressive skillset to build such a complex mill.  I commend you. 8)

Gday Arnold 113

Firstly i want to congratulate you on a wonderful creation that shows your ability to think and re think ......then come up with something that is original....this is clear on many parts of your mill. I dare not ask how many man hours you have put into this but ......it must have been a labour of love. WOW.....really love all the little inventive bits.
I'm usually a lurker on this forum trying to learn but you forced me out.

All the very best with your teething issues and keep up the great work.
John

Thanks everyone for all the kind comments. It really means a lot to me.
I first started, about 5 - 6 years ago, to build a saw mill (just a small, simple mill), but I never do things the simple way. The project started growing, and growing until you see the results years later. I only worked on it a little at a time the first few years but the last year I've worked on it day and night. I've had to build it mostly out of metal I got at a salvage yard because being retired the money just isn't there for things such as this. The way I've done things a lot of times was dictated by what I found at the salvage yard.
I'm always ready for visitors so just give me a call and come on by.  Thanks again.. Arnold.

Thanks for you comment RADDA.DADDA, (John).  I suspect that you have much information and knowledge that you could share.   ;D

CaseyK, Yes the motors are 24 volt wheelchair motors but I removed the brakes. I needed to mount encoders on the motors for feedback to the controller. The controller accepts commands from a PC or microcomputer and then tells the motor drive what position to go to and at what speed. It also keeps track of where the motor is by way of the encoder feedback. The controller is called a Kangaroo and the PWM motor drive is called a Sabertooth. The drive and controller takes care of two motors. They were engineered for robots (as in robot wars). They are sold by Dimension Engineering.
I assembled a remote control using the two 12 channel remote transmitters so I now have a 24 channel RF remote. When I finish up the microcomputer program and get the motor controller tuned I will be able to run the bandsaw from the remote.
I uploaded a few more pictures today so I'll post them.

 

This is my diesel drip band lube. It is applied via a felt wick.



 

I also have a water lube/coolant system using the same felt wick.



You can see the two tubes coming down from above. I just hook up which one I want to use. The felt wick wets both sides of the band.



This is a shot from under the band carriage. You can see the linear positioner for the engine v belts tensioner.



I was concerned that my carriage might tip over so I made some brackets that hook under the rails.

vfauto, The next three pictures and a drawing will show how my log stops work.
