Cake: Just a little talking would go A LONG WAY. I had to click through 3 links
to simply find out what you used for a motor, You should definitely tel us
how you did all this, it really is a great grinder. Where did you salvage
your final motor? What other motors work? Are there any other salvaged
parts in your build? If you could improve it in any way how would you do so?
Thnks for the video and time. Alex
STRIKER520: It is more of an item for people that make the knife not sharpen.
Alvin Z: Is it possible to make a small version, and if so do you mind marketing
them :). Great job though
twodeadpoets: You get an A+ AND five stars!
ignilc: how did you center the belt ?by using a crowned pulley? great work by the
Snack3828: Good Job! I love my belt grinder. I use it every day.
Feukair: @Thetruthishere11 Using the top of the belt means the dust comes right
towards you, instead you would remove the platen and use the front. It's as
big as it needs to be to allow for 72 inches of belt ;-)
labrat7357: Top job. Re: your vibration getting to the work,you can make very effective
isolating motor mounts using the heavy rubbers from the spindle of shock
absorbers they are about 1 1/4 dia by 1/2 inch thick. get 8 .Use 4 to bolt
motor to a plate and then seperate a second plate from the first using 4
rubbers and 4 bolts on the corners. It is this second plate that is bolted
down. Also the drive pulley is a long way from the bearing ,that can cause
problems also. All the best
Feukair: The tip of the screw pushes against a small plate that the tracking while
axle is mounted on. The plate is mounted at the top on some pins. The
tension of the belt puts downward pressure on the tracking wheel. The screw
going in or out pushes the bottom of the plate in or out a little, causing
the wheel to move up or down just a bit. It's a standard design modeled
after the KMG grinder. The tracking wheel needs to have a crown. I bought
all the wheels from beaumont metal works.
Feukair: Yes that was a washing machine motor, it was only a test, not nearly enough
power, the belt stops easily with a lot of pressure. See my other video
link in the comments to a video of the replacement motor.
CsaptukEst: Hello! What do you think, could a washing machine's engine power such a
kickass belt grinder? :D
alb24u: Like J said, get the Fenner power twist belt. I had a vibration problem and
that belt fixed it completely
Lunchlady6610: Very cool that you made that youself! It does an awesome job shapening.
William O'Connor: Please make a tutorial !!!!!!
randall petermann: unless you are a pro knife sharpner seems like an awful pricey machine to
keep your pocket knife and a couple of kitchen kives sharp
Feukair: @helicrashpro I had upgraded the motor and pulley system, please see my
other video called "DIY grinder, now with more power!!!"
enginemaxcarb.: do the wheels have ball bearings???
Jim Hinson: Have you tried using a power twist belt made by Fenner drives to reduce the
mindfreak001009: when you said 72 inches' is it the circumference? thanks
triumphmanful: Is that a washing machine type motor ? , I can't see it clearly!
jameasun: very nice and clean grinder. Where did you come up with the wheel?
Feukair: Of course I don't mind. Mine is a copy as well, it's just a sort of KMG
clone but mounted on a pole. There are a few other similar pole mounted
designs on utube.
Bill Ling: Is there anywhere I could get plans for this? Its about as close to a KMG
as i'll get without buying a KMG.
helicrashpro: Looks very good but it sounds like it runs pretty slow, more like a sander
than a "grinder". You could change the pulleys and get more SFPM out of it.
Tkim8574: do you have plans for this belt grinder yet/
Feukair: 72" is the length of the belt so yes the circumference. 2" belts typically
come in 72" or 36". Longer ones are more common for knife grinding because
the longer surface area keeps a little cooler and lasts longer.
Thetruthishere11: do you use the horizontal top side? looks too big.
Feukair: Thanks for the comments, I still have some fine tuning to do on the drive
mechanism, vibrations are getting up to the working surface. I need to find
a way to dampen the vibrations, I'm thinking of re-designing the motor
mount so it's not mounted to the vertical shaft of the stand.
gordonquixote: Sick grinder!!!!!!!
ortonomics: Very nice design, sorry about the vibration tho, that's a bummer but I bet
you are right its the drivetrain/motor.
Tkim8574: do you have plans for this belt grinder yet?
Alvin Z: Making*
mindfreak001009: thanks a lot,would u mind if i clone your design?
HogSnot: Very nice. Looks very well constructed. Would be great if you shared your
plans! (yeah, I'm a greedy bastard).
Denton Markwalter: How do you make the belt move back and girth with the screw? I am planning
on making one soon. Also, did you turn the pivots yourself?
enginemaxcarb.: i have to make one of this machines...
Feukair: Yes, except for the drive wheel. The wheels from beaumont metal works come
David Spiller: nice job !
Feukair: I didnt really make any plans. There are so many designs and pictures
online I just studied them until I understood the basic concepts of the
design components, then I built it. Made a few sketches and whatnot for
measurements and such, but that was it.
immaxbuddy: Wow, impressive job, it looks like something factory made, not home made. I
think if you isolated the motor with rubber busings it would do the trick,
as far as reducing vibrations. I'm going to build a grinder like yours, I
think your simple but effective design is excellent. Thanks for showing it.
