band saw mill project

[RAYAR]

I just have a few parts gathered up for the tooth setter at the moment and a sketch started.. I'll have to start a thread on it when I start building it.

 Changed my gear box from a 25 to 1 ..to a 40 to 1 ratio and added a second smaller jackshaft with 2 to 1 ratio sprockets ..... I'm at 18 sec for 12 inch of lift with my 2.5hp tread mill motor (had started with 6-7 sec for 12inch of lift but would have burnt my motor quite fast)...next step is to add my garage door spring to help with the weight..Don't have the motor bolted yet..hope i don't have to down gear again :-\

[Darrel]

The setup looks good and while it does sound like its a bit slow, I'm guessing that my old LT40 isn't much faster.

I wouldn't be concerned about the urethane wheels longevity. I have seen rotating urethane coated cylinders outlast steel cylinders in much more demanding environment than your mill will ever experience. there  are also companies that will resurface them but at what cost? As far as your blade guides, make them out of 4140 steel and they can easily be hardened.

[Vautour]

   @Darrel..was putting that out there to see what average speed is normal  tks .@Luap..hoping those urethane wheels hold also..gonna keep those guild wheels till they wear out and then do them again with proper steel..tks

got my bandsaw mill motor...04 TOYOTA YARIS 1.5litre...

I was very tempted to use my saturn motor 1.9 twin cam. I was concerned it would not have enough low end torque. be very curious to know how that turns out.

[Vautour]

.........@ Crusarius...i would Not worried about low end torque..for example this motor has 50hp at probably 2000 rpm... so i'm gonna run it at about 1500rpm with a 6 inch pulley at the crank...motor is bigger than i had anticipated ..i worked in a scap yard and some car had some way smaller lighter motor..

The beast grows!

[Hilltop366]

Interesting power source,

Found this:

[th]Torque[/th] 105 ft-lbs. @ 4200 rpm [th]Base Engine Size[/th] 1.5 L [th]Horsepower[/th] 108 hp @ 6000 rpm

[Vautour]

@ Woodpecker ... hmm like the name  "the beast"..might work haha.............. ....@Hilltop366...Interesting power source for sure.. 2 hrs to get the motor out...4 hrs to remove dash and remove complete wiring harness...bench testing gonna be real fun i bet :-\..always liked good challenge..haha

... Since there is a log arch topic.. i just finished mine up
 

 

[RAYAR]

Nice log arch. That's a project I'm planning on doing too.

[Vautour]

 

 After several months.. the mill is on the front burner again...just installed a 24volt electric forklift motor (permanent magnet) and a bigger gearbox (ratio180 to1) tried it out yesterday and was finally happy about the speed lifting the head assembly up at about 6sec. per foot...even tho the engine is not installed yet i seemed to have plenty HP for the extra 200 pds 

[RAYAR]

It's nice to see that your mill build is progressing again.

[Vautour]

... @ RAYRAR..hopefully i'll be making sawdust by next year..got my two barrels of wast oil for heat ... next few weeks will be installing the echo engine.

[RAYAR]

With that waste oil heat, you'll have a warm place to get your mill ready to go. Mine is still set up at the shop in town, not sure if it's going to stay there for the winter or tow it home.

I have to give the OP a hand,very creative ideas to say the least .As the old saying goes ,"one mans junk is another mans treasure " smiley_clapping
 

[JoshNZ]

God forbid that saw beam binds somewhere, it doesn't look like that motor and gearbox will be waiting around for it xD

[Vautour]

...Tks Al Smith.....lotsa good thinker and fabers on here to comment and help anyway they can                                                                                  @JohsNZ.... motor will turn a few turns after the power is off so i'm not to concerned..more concerned if my gearbox chain breaks..i don't have the safety like acme rods...  was doing more test Sat while standing on the head part (180 pds "engine weight") still raising about 7-8 sec per foot..

[Al_Smith]

Truth be known a lot of us tinkers and puttsers must have came from the same bolt of cloth .I like the challenge  myself . ;)

[Al_Smith]

If that reduction unit is a worm gear you won't get an overhauling load heavy enough to over ride it .Big heavy link chain takes a lot to break it .
I suppose there's options for a back up dampening  device in case of a failure for safety reasons .Could be long air cylinders with check valves which would act like shock absorbers or a ratchet /pawl device ,inertia brake .You'll figure it out I have no doubt .

[Vautour]

 

 Finally bench started my echo engine for the bandsaw yesterday..after i get it bolted on with rad exhaust and fuel pump installed can i dissect most of the wiring :-\... a carburated engine would of been so simple 

[Crusarius]

I was so ready to cannibalize my old saturn SL2 for a new mill. but I felt the added size and weight would not gain me anything in the end.

I dunno. I may still do it on the next version. We will see.

[Woodpecker52]

My woodmizer cuts anything I want with a 14hp k holer motor.  I use to have a 671 Detroit diesel but would never want it mounted on a band saw head.
