Вставка

- WELCOME TO MY CHANNEL - HIM AND I Garage !!
I recently burnt the motor out trying to cut through 2 2x4s
I have had this bandsaw for about 2 years may be 3??
The motor that comes with the harbor freight bandsaw is just to weak to cut thick wood
I upgraded to a leeson 1 hp motor and wow did it make a difference it’s still slow going but at least it’s cutting!!
Thanks for watching & Stay with us!

This is a very informative video as I often contemplate doing an upgrade like this. You showed the motor comparison, the problems, taught me big potential issues to watch out for etc. I really appreciate this. Something that suprised me was watching this bandsaw cut. It appears to me that my old Sears craftsman 12" tilt head and my standard model 12" craftsman both cut better than the saw in the video does.
You'll find that Harbor Freight 3/4 HP motors usually test at 1/3 HP.
Yeah they are garbage!!
This is informative! Because I swear my old Sears Craftsman tilt head and standard model both cut better than harbor freight! I never would have thought.
What was the motor specifics you used for the new one, ie shaft size, rpms, etc. THANKS
I never new the gray version had a 3/4 hp motor. I have the older green version and it came with a 1hp. I have a 1.5hp Harbor Freight motor I should swap in... I figure the 1hp can be used for a drum sander build..
Old swamp cooler motors are great for this type of stuff.
Thanks for letting us ride along during your troubleshooting. Good video and good information. Just curious, did you ever try a new blade? If so, were the effects significant?
Same blade I might do another test video on the new blade
Once I got the right belt settings it was a significant change from the old motor
great video!! Doing the sane upgrade...can you tell me the leeson model number?? Also is your shaft size still 5/8? thanks!!
I did not have to do anything for the shaft it lined up perfectly. Model number m6c17f810L
Excellent video! Can you help me diagnose why my machine shakes and what causes that squeal? I just picked up a used saw. When it was demonstrated it ran smoothly. When I replaced the blade - no matter what setting I tried, it was never the same. The spare blades he gave me were thinner than what was on it (which was dull). Is there a way to merely adjust that shaking out? Thanks!
Have you tried changing the tires the rubber around the wheels?
@@poultonprojects I haven't because they look good. I'll look at them more closely tomorrow. Thanks!
That things all moving around, im not sure if i'd feel safe running that thing lol
Great video. More Horsepower Rocks. Test number whatever, LOL.
Glade to see I'm not the only one that has problems doing something simple. LOL From my experience those belts you're running rob power BAD....
i bet they do know that i think about it
Do you think the original motor would have been good if you had changed the belt/pulley to where you put it where it is now? I am also having the same problem with the same saw. I don't use it in the winter but I will try changing the belt to the higher speed as you did and not, hopefully, change the motor.
Great questions.... I do believe it’s just a weak motor that can’t handle larger wood. But I would love to hear back from you and see if it helps
Nice video! You should study how gear ratios work so you have a better understanding of big pulley vs little pulley and their relationship to each other. I would also level up that saw so it won’t rock while in use. Thanks for taking the time and sharing!
I would have someone make you an aluminum insert, makes a big difference. I had one made, big improvement with short or small pieces!
Where is the insert go?
Does
On the table around the blade. Replace the plastic one.
Was there any way that you might have set up the saw with the original motor that could of handled the legs or was it truly underpowered so badly that it was never going to do the job you wanted? This turned into a pretty darn good video ... well done.
I tried multiple variations and any thing lager then 3 inches was a struggle I bet if I would of had a 3tpi blade it could have worked but still think it under powered
That factory motor has no power, even with a 3 tpi blade it's very easy to stall mine. Great video thanks
I predict you will be a lot happier with your saw after reducing your blade pitch to 3-4 TPI.
At 3 TPI you'll get rougher cuts in thin wood, 3/4" or less. And be careful about snagging dowels and small pieces. But you'll get straighter cuts without the struggling, and the blade will last much longer before it gets dull and no longer cuts right.
I can make those cuts on a 2.5A saw.
Ohhhhhh thanks I will try this out!!!
What blades do you recommend
On my 14" saw, I like to run a 1/2" blade 0.025" thick, and either 3 or 4 TPI. If I didn't also have a smaller bandsaw, I might prefer a 3/8" blade, 0.032" thick, for the ability to cut straight in thick material and to cut tight radii.
The downsides of a "too coarse" blade are pretty minimal. When you cut thin sheet goods and boards, who cares if you waste a tiny bit more wood in the kerf/finishing?
I cut aluminum and brass, too. No need to change blades.
The 3-4 TPI blade will also be able to graze and shape, in case you missed your line, without having to hog off a lot of material with a sander!
@@mildyproductive9726 I just put the 3 tip on my bandsaw holy crap!!! What a difference!!! So pleased I resawed my first hardwood over the weekend I can’t thank you enough!!!
I have the same fn problem
The Olson FB 23193DB 93.5 x 0.5 3 tpi blade works well for re-sawing even with the standard motor.
good deal just got one in my cart will try it out
Look for an old delta . They're the best for the money. I bought one for $100 with riser block.. Don't waste your money on Harbor Freight.
You need to stabalize the entire saw.
I think you need to change your blade
I did I got the lower tpi and it’s been great!
@@poultonprojects i had the same issue, i was struggling to cut some soft pine. It felt as if i was cutting 5 inch walnut with a 18v dewalt saw, it was a struggle. but once i got it replaced it was smooth as butter. I look for wood to cut now, even scrap wood.
😂😂😂😂😂😂
Bro this sucks you didnt put a new blade on it and said you would to the cut in real time and cut it off...
get a new blade man, that thing sounds awefull
just got the 3/4 inch 3tpi omg its amazing!!!
