howdy all
as many know im building a home made mill . well i thought about when the day comes for some hydraulics . what size pump would i need . might be in my buget to put in the hydraulic saw height adjustment now . i do have heat and tv in the dog house you know      steve

[sgschwend]

Not too big, I am running a .7cu inch and it could be a bit smaller.  When the pump gets too big the motor driving it needs to run at a lower rpm, and in my case the motor is an axillary gas engine, it would prefer to spin a bit faster.

[steve phillips]

hey sgschwend
 thanks for the info , what size cylinders are you using

[rwthom279]

Howdy Steve,  Have you considered using a 12 volt motor for height adjustment, or even a winch?  You have mentioned about budget/costs, etc. and I feel your pain.  My mill uses 12v motor for lift and the rest is hydraulic...I can get you the pump info if you want.  Works well for hyd feed and log loader.

Steveo,as you've figured out by now the big bugaboo with hydraulics is getting hyd. from the band carriage to the base and vice versa.You can festoon hoses or use the cat track boath are too expensive.A small hyd. pump on the carriage to raise and lower and a feed motor to move the carriage.The log loader and turner  need a seperate system,very much simplfied if your mill is stationary with electric [110].Things can be simplified if you handle the feed from the base and just manually lift the band head.Frank C.

 yeah after a lot of thinking believe i will see roller chain in my future for lifting head .
 but i will still keep in mind about future hydraulics when building. dont know if i will even need them .
  my plan is  ,i am on a slight hill side and i am going to use mother nature to help load the log on the mill. by putting the loading side of mill towards the hill side, should help rolling them on.
 i will be mounting rail on 6x6 and using it as a skid for now,untill i built something ,but fence 1st

My Turner mill is equipped with electric winch height adjustment, and it is one of the things about it that I don't really like, since it is hard to stop the button exactly where I want it, and the cable and pulley system seems to allow for a little bit of imprecision in height from side to side. I would prefer it were a manual system, maybe like on my cousin's Norwood. I can't remember the exact setup on the Norwood. But if I were designing my own, I would consider using a rack and pinion setup with a lockable hand crank.

after sleeping on it  ,i see chain and crank handle in my future .

#60 roller chain is cheap and sprockets  arent that bad either . i will visit a couple of bike shops i do machine work for and get there throw aways

have you ever met such a tight a$$
so far with engine and track metal , and 90 % of misc metal i have less than 300 bucks in it . that includes wheels ,track rollers , pillow bearings . 500 is my goal

[eastberkshirecustoms]

Hey Steve, that's pretty ambitious. I think you forgot a '0' on your goal price

[ladylake]

  My B20 uses a 6hp gas motor with I think about a 5gpm pump, runs the hydraulic real nice.    Steve

    Steve         If you are going with chain you might check        Mister Sawmill Model 26     they have a pretty neat set up.

My first homemade mill had 2 pcs. of 3/4 allthread on each post...(it was a 2 post unit..)  I put sprockets on top of each threaded rod with 60 chain.....It was 10 cranks per inch.....I'll let you do the math on how many cranks to go from a 1 inch slab to a new 26 inch log....My new system is like a Hud-son with a winch crank and pulleys.
