Larry Perna: Very nice job! Thanks for the video and the ideas.

Dale Richardson: Excellent piece of work! How did you acquire the large aluminum and the wheel on the motor? 

tellket: Very nice! He'll of sick monster look too. 

bubby hardy: Hey man, that grinder is crazy awesome!!! I am currently building one from a treadmill and love all the cool ideas!! Really enjoyed watching!!

klawndyke: ok now thats awesome 

Herman van der Merwe: Brilliant!!!!! I love it!!! I'm looking into making knifes myself but the equipment is too expensive at the moment for me. I also like recycling and re purposing All kinds of stuff so this idea is just awesome!!! Thanks for the upload Marcos!!

Raffaele Caré: I've seen someone use the skateboard wheels, but the truck tracking adjuster is a new one! great idea. How did you have the center rotating portion made? Was it laser cut or did you machine it yourself? Thanks for sharing.

Michael Flynn: Nice build Marcos

Michael Anway: Marcos this is brilliant! Especially so for using so many of the parts from the treadmill,I see them on Craigslist all the time in working conditon for free! Now I'm going to have to pick one up soon.

Alamodem: Best designed grinder i've seen. Do you have any place we can download drawings or plans? Thanks for sharing.

tosee forall: Fantasic job, good to see material repurposed, keep up the good work. Excellent design by the way.

russ meek: Cracking machine that marra ,fantastic use of recycled parts and a bit of ingenuity, all the best with you knife making,I have just started messing about myself, Russ

Jeff H.: Limited fabrication skills aside, that's a nice machine.

Scott H: Hey Marcos, That is one outstanding job you did with your belt sander. Your abilities exceed the normal garage DIY"er. Nice work, Real nice. An outstanding job and very functional. I like you re-purposing also, You "brainiac" Speaking of re-purposing...... I'll give ya $30.00 for those four wheels from your stroller hanging up from the ceiling in the corner of your shop....haha just kidding..........nice work and get some more vids out.. Scott

David Spiller: Awesome job Marcos!

mars1952: Wow! That is a nice looking belt grinder! Nice work.

Paul Roberts: Awesome. Love the work. Good Job.

Sean Barrow: Great job! Where did you get the big wheel, and where will you get different sizes ones? You've inspired me, I'm going to build one myself!

Ronnie Kephart: Marcos, what is the center metal piece-where did it come from? Someone asked but I haven't seen answer. Great idea. Did you ever make any more videos?

Steve S: Where did you get the center piece of metal that the wheel and flat platen in mounted on?

John Armstrong: Pretty darn good ingenuity. Looks like it will do the job quite well!!! I'm impressed!!! Ya need to sell the plans. I'd buy them if available.

Steve Kurta: Super job. I'm planning for my 2x72. Love the truck adjuster and skateboard wheels! The rotating wheel-to-platen feature is crazy smart. Very motivating and great ideas. I'd like to see how your blade holding jig functions, can you do a demonstration?

wambolt1212: things awesome bro!

Sam Parker: I have been researching retail belt grinders all day and this has more features than those do. Many DIY rigs limit features for simplicity but it seems like you have really improved standard retail units with this setup. With the smaller wheels that you mentioned it should be even more versatile. I would think you might have to replace the skate bearings with more industrial ones fit for purpose but I assume you have that covered already. Thanks for sharing.

Jose Figueroa: Wow! Good lookin machine looks store bought. Great job

hasdrubal121: Well done, nice job there.

Scott McCarroll: That's brilliant very clever 

MochaTim: One hell of a job on the design and build. I would be interested in more detailed specs.

banjoman22: Awesome!!!! great work

James Johnson: amazing.

venun tox: O melhor projeto até agora,muito bom ...

Jose Figueroa: Thanks for responding Marco, I wasn't sure but makes sense guess I was worried about start up on the motor as well. I'll keep a look out on cragslist for a free treadmill thanks again. & Happy holidays.

JoeSmith: This is by far the nicest home made machine I have ever seen, If you can figure out how to put such a thing into production, you are going to be set.

Frank Fomkin: Wow' fantastic work. I have been pondering a diy grinder and yours is very inspirational. I recently broke down my old treadmill for scrap but that was before i discovered knife making.

GnosisMan50: you might have to seal off the motor to prevent it from getting sanding residues

dale evans: Looks really nice I like it Your tracking changes because your tracking truck rotates on its horizontal axis. Another adjustment at 90 degrees might solve that.. I am in no way being critical, great job

Abracahandra: Great job on the grinder my friend! I am in the process of making a grinder myself. 

Nathan Dean: Great idea 

Jose Figueroa: In the process of making one myself. got my hands on an old aluminum jet ski trailer lots of tubular alum, was wondering if a 15 amp dimmer switch would work for the motor speed control ?

aurora52378: been hunting for a good design for my next grinder... this thing is AWESOME!.. Nice work!.. 

Alamodem: That would be amazing. Even just the pivot part between the wheel and the platen. 

Nick Cattafi: Absolute genius innovations. How did you construct the main piece the flips,with the large wheel on one side and the platen on the other. Where did you find that piece. That is where my plan stall as i do not have a welder I will need to repurpose something else. I agree with others,if you sold plans,even simple one,I would buy them.

xXTepicwinTXx: Hey Marcos how did you design your flipable/modular contact wheel to flat sander? Did you draw that out in auto cad and had a plasma table cut that piece out? Or how did you do that?

danny burgess: that is THE COOLEST grinder I have EVER seen !! awesome job

slickdeville: freaking amazing....well done.

FunkinTwisted: I love to build things too and do a fair amount of DIY building. But I have to say, this is outstanding. You have done a great job with an impressive machine........ you should be proud!!!! Do more.......... post more.

wb93612: Awesome. Well done. Thanks for posting the video. That gives me some ideas.

Hashirama Senju: Nice job brother!

hellsingmongrel: Uhhh, these are not hard facts to know. I already knew this, and yes, I have natural tits!
Aoife Barniskis: I bought the Almay apple a day over the winter and I absolutely love it! It's hydrating, smells as good as Emily says, is comfortable, is a little sheer but shows up great on my highly pigmented lips. On me the color comes off as a darker, cool, red, perfect for anyone who wants to try out red but doesn't want to commit to a bold color. Also, there is no glitter or shimmer, just gives lips a juicy look. I love the color and formula and will buy it again when I run out.
Iain Stevenson: Hi Graham I have been exploring with my Lumix Z30 and pretty happy with it. Your videos have definitely helped me optimise many of the features. However, I am still having a diabolical time taking night sky shots, especially with a bright moon. I have tried numerous settings in several modes but totally unsuccessful. Any possibility of a brief guide on night shots with this camera? 
S Max Reiter: Dear nerdishcouk, Thank you for the vast and entertaining review! I enjoyed the example range of view through all your lense's up to the 8mm. I'm looking for a lense primarly to take video indoor on my mirrorless camera for my real estate job. Then for fun scenes for my home videos. I'm still on a budget and can't afford a nice wide angle lense. Do you think this will be a good addition to my 22mm, 18-55mm canon eos m lenses. Canon eos-m camera indoor & outdoor photography/video w/ tripod! Thanks again!
