Ray's Portable Manual Mill Mods & Additions

Installed a log loading winch set-up this past afternoon. Can be used from either side. Still need to weld a short section of tubing to the top center of the slide tube for the cable hook for winching. Also still have to construct the loading ramps.

Made two trays, the larger, heavier guage one goes under the carriage, which is over the axle, when in the travel position to hold the lube and fuel containers.

That looks nice. have you used the winch yet? I would think your going to want some triangulation to support that tall post. Sure looks like its going to want to bend with a large log.

I bought it last July, already built several years ago. I've since made several improvements on it. The band wheels are spoked cast 18-3/4" V-belt pulley type. (I hope this is what you are asking about)

Not used yet, just installed yesterday. The post is not really that tall and it's quite rugged, actually. It's sporting a 2500 lb winch with 50 ft of 3/16" cable.

Hi Vautour, I did not build this mill, but suppose to have been built by someone in this area likely around 2005-2006. My mill is not large compared to your mill. Your mill would need a good sized set-up. Just thinking... maybe two jackshafts linked in tandem together by chain and sprocket would be something to think about, but would still need large springs. ???
 
I'm thinking if I had a larger diameter spring, it would reduce the lightness at the bottom and lighten the weight when cranked up as there wouldn't be as much change in tension as the smaller spring is getting.

Manually operated, one thing about this set-up is it gets harder to turn the height adjustment wheel as you get nearer to the top, as the spring tension is being reduced. If I adjust it anymore, the saw head will start to float as it reaches the bottom of its' travel. It's not like an overhead door that slides horizontally overhead where the vertical weight of the door is being reduced as the spring is being unwound as it goes up. The extension spring type would have the same issues. Chains, sprockets and counter weights would keep the weight equal in its' travel, but you'd have to add a fair bit of weight, so not the way to go for a portable mill.

Used my winch set-up this afternoon (Sunday). Worked every bit as good as I expected, even winching logs from a distance, then rolling them up onto the mill.

Anchor point for winch cable when rolling logs up onto mill bed (short square tube in center)





Ready to head out with new winch set-up

Um yes there are several to choose from... :-[
I was wondering about the wheels the saw head travels on.

I was wondering about the wheels the saw head travels on.
Doing a little research, they are U-groove track rolllers. Mine are measuring 3" diameter by 1" thick with a 3/8" wide groove. They are rolling on the edge of 1/4" angle. There is a spacer between the bearing and the carriage frame.

A better view of how my winching set-up works.

This pic shows the travel position, horizontal slide tube centered with pins, cable hooked under a log bunk and snugged up. This keeps the system from rattling and moving while traveling.






This pic shows the horizontal tube slid in against the slide tube in working position.






This pic shows the anchor for the cable hook when rolling the log up the ramps.



 


This pic shows the 4 ft tube slid out to clear the saw head.






When using winch on operator side, the winch can be lifted out and set aside and the tube is left slid in to easily get by it. (operator side opposite side in this pic)







In this pic, it shows where I welded an old bolt under the edge of the tube to keep the winch tube from sliding through making it a drop in set-up  and to keep it open so sawdust doesn't accumulate in it. Hole for a pin not needed in this case.






I don't think I need to worry about 2500 lb humans :D

I used 2" X 2" X 3/16" and the vertical piece the winch is on is made up of two pieces I spliced together, about 29" long. The slide tube is 2-1/2" X 2-1/2" X 3/16"  and 34" long. I also reinforced the ends with additional 3/16" pieces. It's what I had available. The mills' frame is 30" wide.

I set up on the side of a dirt road and done a few single line pulls from the edge of the woods to the mill before doing the roll winching thing up the ramps (just a couple old birch sticks). The heaviest one was a Poplar about 14" on small end. It was cut last summer for a power line clearing and was still in full length. They were just cut down and dozed aside. I cut a 9 ft section out of it after having to cut a few sections off the butt until I got to solid wood. (ants) The winch is a two speed and used in high range of 4:1 ratio. It winched that over with no effort at all. That log was still quite wet when I milled it.

Very impressed with the performance of my winch set-up so far. Worked every bit as good as I expected and then some.

Stopped in at my former work place this evening and started to put together two more cam dawgs like the one shown that I built last year. It works quite well and I don't feel I need to modify it so I'm copying it. Forgot to take another pic of what I accomplished this evening. The only thing left to weld is the loop handles and I'm ready to drill the holes. Also have a little shaping left to do with a disc grinder on a few pieces, mainly rounding some corners. The beak on them is armour plate, so would not want to run a band blade into it. Also need to pick up the hardware to put them together with.

I would consider enclosing those mast rollers and adding a rail wiper fore & aft.

Hi MM, I don't seem to have a good pic of the area where the sawdust exits but in the lower right corner of this pic you can see the carriage roller has a cover and directly behind it there is a plate that extends over the rail to help with keeping sawdust from gathering on the rail. There is some sawdust getting compressed on the rail and rollers and  do have plans on installing rail and roller wipers.

Another place I need to add a deflector/wiper is on that yellow guard in this pic. Too much sawdust gets by here and can cake onto the band support bearings and drive wheel belt. I have already added a back stop guard to this yellow deflector as seen in second pic.




 


Went searching and found a little better pic of this area.
