Building a Great Little Belt Grinder - Part 1

[@TomokosEnterprize]

Great build my friend. Pieces from here and there and a little imagination and wa-la. There be a new toy for the shop. It is always a great visit with you my friend.

[@WinkysWorkshop]

Thank you very much!

[@TomokosEnterprize]

@@WinkysWorkshop It is worth the time to come back and revisit your projects my friend. I just plain like your style eh !

[@WinkysWorkshop]

@@TomokosEnterprize You need a prize for being my top commenter. Thanks!

[@TomokosEnterprize]

@@WinkysWorkshop It is easy. We are much the same and share a common interests my friend. I have a lot of extra time on my hands due to medical issues and you sure help the day go by and still have a bunch to teach others and myself as well now and then. I still think using a piece of plywood, a piece ofb2x4 and a 100 tooth saw to make your dials is nothing short of brilliant my friend.

[@AmateurRedneckWorkshop]

You are doing a great job there Winky. Amazing how a little heat will make aluminum change size. For gear cutting and wheels I use an arbor between centers and that saves all the indicating.

[@WinkysWorkshop]

Yeah... between centers is a good idea! Thanks

[@dwightcarlson7136]

Great practical mythology to locate the plate on the rotary table!👍👍👍

[@WinkysWorkshop]

Thanks... later I realized I didn't really need the hold all the way through. I tried making the motor plate on the lathe and just cut a groove, it was easier and worked great.

[@SantasWorkshop1964]

Great video, I had my mouth full of coffee when you slipped the pulleys together ,omg that was funny ! Thanks for the instruction, going to make this,always wanted one.

[@WinkysWorkshop]

Glad you enjoyed it. I had to go back and watch the video to see what you were talking about. I forgot about that part. It's amazing how much temperature expands the aluminum. I've used the grinder several times a week for about a year now. Very useful!

[@reaper060670]

Hey again Winky.. Those pulleys that hole the belts in place are fairly easy to get made up now. I don't have the tools to make them bro but I love the design of ur grinder. I was thinking about buying one from VEVOR but maybe I will take a stab at building my own with the disc sander as part of it too.. This Old Tony is another channel I watch. U mentioned him on a video I was watching last night. I first found his channel bcos I'm trying to build my own CNC Router atm. It's the electronics that scare me a little but I will get it done soon enough man.. Take it easy man.. Another great video btw Winky..

[@WinkysWorkshop]

Yeah This Old Tony is really fun to watch. I learned a lot about TIG welding from him before I ever got a TIG. Yes, Vevor has a good deal on the grinder wheels. Thats a good way to go.

[@rayfalcoa1955]

all i can sAy is sweet,looking for the next one .thanks ,mark for sharing.

[@WinkysWorkshop]

More to come!

[@JamesDedmon]

I like the concept of how you built the grinder

[@WinkysWorkshop]

Thanks James, I was shocked at how much difference the larger drive pulley made.

[@CraftedChannel]

I know your already done. When I was kid, the bike fixing old neighbor man would tell me he was going trim my ears back when he got tired of me pestering him. I'm thinking that motor could have it's ears trimmed back to make up for the thickness. Also, you could notch the top of the plate to clear the belt allowing you to move the pulley in. Full of ideas tonight.

[@WinkysWorkshop]

Haha.. trimmed ears. Yeah it all worked out. The pulley is on the shaft 7/8 - inch and it is very good fit. But good idea!

[@bobnwashington5966]

I commend you on the video, right to the point, we already know how to drill, grind, etc. subbed.

[@WinkysWorkshop]

Thanks... I agree and I'm learning. Past videos I have included too much detail

[@rickpalechuk4411]

That slug was priceless!

[@WinkysWorkshop]

Oh... you mean the steel in the aluminum pulley? That's the second time I've done that... blows my mind.

[@airgunsfreedom700ssp3]

I woud have left the steel slug extend out of the aluminum to compensate for the 1/2" plate on the motor mount. That would give you more purchase on the mandrel .

[@WinkysWorkshop]

Excellent idea!

[@peteredwards9147]

Fantastic video and skills

[@WinkysWorkshop]

Thank you! Cheers!

[@aux1z11]

Great job, I'm going to make one out of a treadmill with a 2.5hp DC motor and get some wide sanding belts made for it.

[@WinkysWorkshop]

That's great. Although the narrow belts are more forgiving about tracking

[@kentuckytrapper780]

Great build winky..

[@WinkysWorkshop]

Thanks... another daily used item in the shop.

[@EverettsWorkshop]

Got a 1.5hp motor that was formerly attached to a hydraulic pump, you've got me thinking one of these would be a good use of that motor. On to part 2.

[@WinkysWorkshop]

You might have to make the 6 x 8 mounting plate a little bigger. Sometime a 1 hp or over motor is bigger. 1.5 HP is a little overkill but it would work well.

[@TheWrate]

Great video, thanks for making this!

[@WinkysWorkshop]

Thanks for watching!

[@dwightcarlson7136]

Well deserved applause when the steel cylinder dropped into the aluminum piece. 👍👍👍👍😂😂😂

[@WinkysWorkshop]

Thanks, it always amazes me how much aluminum changes with heat.

[@davemason6273]

Nice job. 1/8" per foot for the crown for drive belts, but like you say, not critical, as long as you're not breaking the back of the belt.

[@WinkysWorkshop]

1/8" sounds about right. The crown I made works out almost right. I do know that the belt material plays some part. Like if a belt is stretchy and conforms to the pulley more crown is needed. Thanks

[@ke6bnl]

good video, I have been collecting parts for a 2x72 but other project keep getting in the way.

[@WinkysWorkshop]

Thanks... and I know what you mean about the other projects!

[@kretekfilter9687]

14:52 sir,.that is really hillarious. I watch your video tediously with full attention, and suddenly it just happens,.Well, i think i will keep that in mind..he he

[@WinkysWorkshop]

Yeah that surprised me!

[@compassprecision]

Great sound effects! Lol another good video.

[@WinkysWorkshop]

Glad you like them!

[@markkoons7488]

In ignorance I made a crowned 12" wooden sheaves with pronounced crowns for a stroke sander. Before the first belt had fully sanded wood the belt split lengthwise. If the axles are parallel it doesn't take much crown to get perfect tracking.

[@WinkysWorkshop]

Wow... I've seen belts get distorted but never split. You are right, it doesn't take much crown or tension on the belt. Just enough so the belt doesn't slip under load.

[@MegaLostOne]

Whats the diameter of the drive wheel? I picked up a pump motor today, pump part was trash, the motor is WAY overkill but I will put a vfd on it if I have to. I will have to extend the shaft out so I ordered in a 5/8 reamer so I can fit it well over the motor shaft (.624) and put a 1/2-20 thread inside then punch a small hole all the way through for the left handed 1/4-20 retaining bolt with a relief cut for the bolt.

[@WinkysWorkshop]

I messed up on this belt grinder play list. If you don't make them an "Official Play List" then part two and three don't follow. Anyway, I just made the play list official so when this video ends part 2 and 3 will follow. In the description under part-3 there is a link with the plans and pulley sizes. Here's the link but be sure and watch the other two as well. Thanks! drive.google.com/drive/folders/1K1kPbT6IHLP9JlTj-6SKtCQXgr5vuJW7?usp=sharing

[@MegaLostOne]

@@WinkysWorkshop Thank you. Looking at the drawings I see the diameter of the drive wheel but I don't see the diameter of the idler wheel. I have actually watched all the video's a couple of weeks ago I just didn't remember you saying the sizes. I plan to watch them again before I start the rest of the build after I get the shaft extended on the motor.

[@WinkysWorkshop]

@@MegaLostOne Ha... I may have overlooked a dimension but you can make it whatever you want... within reason. Too small is hard on the belt. I just looked at the drawing, you're right! I think it's abut 2.5"

[@MegaLostOne]

@@WinkysWorkshop Thank you. I read blue prints everyday of the work week and I thought maybe I was losing it, LOL.

[@WinkysWorkshop]

@@MegaLostOne I'm not very good at CAD but mostly just forget silly stuff. Kind of like trying to proof read. You insert words as you read because you know they are supposed to be there.

[@donswords6671]

Hi. I picked up a motor. Just has the direct power cord/ no switch. Need to install one. Do your belt sander motors have a soft start feature?

[@WinkysWorkshop]

No, not really needed.

[@anthonycash4609]

Wow not sure what state you live in or small town, but here in North Carolina I have found metal recycle places or should I say most of them will let us come in and search for stuff and sell it to us by the pound. Which I should say comes out to be cheep compared to buying it by the foot. One place I go to at least once a month has stuff separated out already stainless all on shelves , steel all on shelves, aluminum all on shelves , brass all on shelves, copper all on shelves, out side and we can just go up and down the isles and look for stuff we want. You might check around you to see if any of them will allow you to look around. The one place I have talked about around me I call it my honey hole for metal. I always check there before buying it by the foot. You could have found your 1\2 x 6" plate there. Just last week I bought 5 pieces of 1\2 X 6 X 1 foot long for under $20.00 good job on the belt sander.

[@WinkysWorkshop]

I had a few good sources for a while but they have kind of dried up. There are 3 different recycle places in town... one never has much, the other thinks all his stuff is made of gold and I'm kind of afraid of the third place. The third place is absolutely huge. They have a car shredder but they run just about any industrial steel through it. This is NO exaggeration... they always have a pile of shredded steel 4 or 5 stories high. Lots of steel everywhere although I'd need to bring a cutting touch to get most of it. They will let you walk or drive around but they have these monster loaders with 6 foot tires running around with little regard. Plus I worry about my truck tires. I really wish some industries person would save steel and resell it. What a waste. Maybe I need to just hang out there for a while. Ha They will sell anything for scrap price.

[@tunafish3216]

I would put 2 1/4-20 holes in the pulley to use as a place to put on a puller in case you have to take it off some day.

[@WinkysWorkshop]

Might be a good idea! Thanks

[@MaturePatriot]

What size rotary table is that, 6"? I only use the kitchen when my wife is not home!! That's how you do a hot/cold press fit!! mrpete says you need about 2 degrees of taper for the crown. It is looking good. Great work. You get you project stock the same place I do...where ever you can find it...cheap!

[@WinkysWorkshop]

It really amazes me how the temp effect the aluminum. It was about .0015 under. 2 degrees sounds about right. It really isn't very critical.

[@RealNameRabbit]

Nice job, i´ve build a 2x48" grinder to, but with 4 rolls and for 45 degree :D

[@WinkysWorkshop]

The 45 might be handy to have. I love this grinder!

[@mr.ranyhomemade2466]

Hi Windy Did you what kine of grove could be use with Belt sander please ? i build one Belt Grinder

[@WinkysWorkshop]

Explain that question again and I'll try to help you.

[@mr.ranyhomemade2466]

Will be good

[@donswords6671]

How did you cut the hole in the original steel plate?

[@WinkysWorkshop]

With a rotary table on my mill. In part-3 I show how to do this in a lathe. If you have one this is easier. kzbin.info/www/bejne/epTOp2iump6GjtE

[@georgepretnick4460]

What is going to keep the pulley from spinning on the motor shaft? No key. The nut alone won't do it.

[@WinkysWorkshop]

I was somewhat worried about that myself on my first grinder but in 5 years it has never been an issue. So far on the new grinder there is no sign of slipping. I don't think it's going to ever be an issue although I agree that it is not ideal. I've seen blower fans held on the same way although I suspect the pump vanes had threads. Maybe I should have cut internal threads and used a nut s a lock.

[@lisag2771]

Pool pumps use this motor and the impeller doesn’t come off.

[@dans_Learning_Curve]

I take it you're either retired or close to it. What do/did you do for work? Maintenance?

[@WinkysWorkshop]

Yeah... retired from a job in the printing industry. I ran a web offset magazine press for a long time but the last 15 years before retiring i had a job as a troubleshooter, or at least that's how it started. It turned into an engineering job of sorts. I spent most my time designing modifications for the machines. I have no degree so I was a cheap engineer. But it was fun and better than working night shift!

[@dans_Learning_Curve]

@@WinkysWorkshop excellent! I can see your creative side coming through! You also mentioned a part from a printing press. Was about to add that to my guess. It'd be fun to have a short introduction video telling of your experiences.

[@WinkysWorkshop]

@@dans_Learning_Curve - Hmmm? Now that is an interesting idea! I think it is cool to hear people's life stories as long as they are not too long and boring. Let me think about this... Thanks

[@dans_Learning_Curve]

@@WinkysWorkshop you could point people to a link to your introduction video. It would be their choice to watch it. Your introductions to your videos are great the way they are.

[@WinkysWorkshop]

@@dans_Learning_Curve Thanks!

[@Spetet]

Loved the drill.

[@mathewmolk2089]

Goood job!!!!! I think I would have stuck an arbor in it and turned it between centers and then flipped it over. - Reason? - I'm too lazy to indicate it twice.

[@WinkysWorkshop]

Good idea! Thanks!

[@gabewhisen3446]

Well clockwise cut is conventional, a counter cut is a climbing cut it's as if one is up hill and one is down hill or level that's why your mill cuts better in one direction

[@WinkysWorkshop]

Are you talking about the rotary table? It doesn't make any difference if the mill is cutting full width like a groove although technically cutting a circle would be better clockwise. My rotary table is kind of wimpy. I'll avoid using it like this in the future.

[@bobmcgee7805]

Why remove the flange ? it won't harm will it ?

[@WinkysWorkshop]

The flange is not needed and yes it creates a problem. If the belt gets pushed out of line it will climb up on the flange instead of going back to center. Sorry for the delay.

[@dwightcarlson7136]

Is your rotary table powered? Link to where you bought it?

[@WinkysWorkshop]

No but that would be great! Maybe I'll build one just for cutting circles. That would be handy.

[@WinkysWorkshop]

It's a cheap little table... grizzly I think. It'd good for positioning but after making this cut it's messed up. I need to take it apart and see what happened inside.

[@dougkonopack4693]

Why not mill that plate down to .5 inch ?

[@WinkysWorkshop]

I probably should have found a steel plate... 1/2" is a little thin for aluminum I think.

[@casesandfakts]

Super

[@WinkysWorkshop]

Thanks, I agree. The most used tool in the shop!

[@robertks7343]

What is the diameter of the drive pulley?

[@WinkysWorkshop]

It's 4.5". Here's a link to part 3. Below the video there is a link to the plans kzbin.info/www/bejne/epTOp2iump6GjtE

@@robertks7343 _ No problem, thanks for watching

[@robertks7343]

I can make the pulley out of steel or aluminum, do you think solid aluminum would hold up ok?

[@WinkysWorkshop]

@@robertks7343 - I used aluminum with a steel core but solid would work great as log as you get a good fit on the motor shaft.

[@douglasthompson2740]

An additional quarter inch could be gained by using countersunk bolts on the motor mount. Stove bolts would be a good choice. Enjoyable project. Doug

Thanks

[@RagsdaleCreek]

Part #1 👍..... Going to part #2

[@petepeterson4540]

I guess you don't have a mill to take that aluminum plate down to a half inch with a end mill

[@WinkysWorkshop]

That would work.... although I would be somewhat worried about strength where I bolt the 2 pieces together. Although... I could have overlapped the joint the other way and had a good wider surface to bolt to. Good idea! In the end it worked out well, The pulley is on the shaft 7/8" and it is a very good fit. I suspect it will never be a problem. Thanks for great comment.
