Carbide Grinder Junk Build-

My 'cutting tool' for #Roughcut2022 is building a slow speed carbide grinder (a la Glendo Accufinish) out of some random bits of junk I had laying around the shop. I feel like I rushed though this one, made a bunch of mistakes, drill a lot of extra holes, but somehow managed to make a functioning- if not yet refined- tool. Now I can sharper my scraper blades and start moving closer to rebuilding my milling machine.

I promise I'll still mostly make stuff out of rusty junk and not just buy shiny things with your money.

Always nice to see a chef use the whole animal!

[@joell439]

That sure sums it up nicely. 😂

Im pretty sure you goin to build a spaceship from scratch soon. Super cool Jeremy. I want one for decades 😩

[@DangerousSportsForSeniors]

101 uses for a dead treadmill. Thanks for sharing

[@ollysworkshop]

That was great. I like turning 'scrap' into something useful. Your narration is very engaging.

[@CraigsWorkshop]

Next week, Jeremy uses those diamond disk off-cuts to make a working Odd Job spinning death hat (James Bond villain).

[@CraigsWorkshop]

Nice work though Jeremy - I need one of those too. I think I have an incline motor kicking about somewhere here...

[@davidsnyder2000]

You seem to be able to fabricate anything from scratch. Pretty amazing

[@jeremylastname873]

That’s just cool. Waste not, want not. 😎

Good job. 👍👍👍 Thanks for sharing, Necessity is the mother of invention. The head is not just for growing lice

General and special theories of relativity share Einstein's head with lice.

From junk to useful. That's how we like it.

[@TheKnacklersWorkshop]

Hello Jeremy, Looks like you've got the basics done there and have a machine that will do the job really well... enjoyable viewing, thank you. Take care. Paul,,

[@jdmccorful]

Interesting "minds eye" construction project, possibly a "tongue in cheek" conception but quite functional given the motor problems. Enjoyed watching !!

Jeremy Makes IMPRESSIVE Things. Very interesting, entertaining and informative. Thank you for posting. 👏👏👍😀

[@stevendephillips2490]

Like the way you show the mistakes. Its exactly how things usually go when building something from junk. Very seldom does it go or come out as planned.

[@bobweiram6321]

You can also use adhesive magnetic sheet cut into a circle and stuck to the platen.

[@MatthewTinker-au-pont-blanc]

Steel running in Al makes a pretty good bearing! Leave it until it wears out, if ever!! Cheers, Matthew

[@russterman1]

Love the follow rest at 6:40😆

[@homemadetools]

Good work. We shared this video on our homemade tools forum this week 😎

[@jimsvideos7201]

Here's something I need to make, thank you for the perspective!

[@HenryShiley]

I've been collecting parts to make a similar slow grinder, lol. I wish I had access to machines like you do! My tiny apartment lacks lathe and mill room.

[@EmmaRitson]

thats VERY cool

[@frankward709]

Very cool that's gonna come in very handy Thanks for the video

[@charliemyres5450]

Clever creation Jeremy. Rather than press a small shaft and run the risk of bending it; machine a sliding "thumb-fit" and glue the parts together with Loctite, which is so much safer than Super Glue. Loctite Shaft and Bearing Mount if you want to dismantle it later; Loctite 680 for a permanent bond.

[@bobvines00]

Jeremy, nice job of _creatively_ building your carbide sharpener! I always look forward to seeing whatever you've come up with to share. ;) When you first used the diamond wheel, I half expected it to be one of those counterfeit wheels that loses its diamonds almost immediately. Back in the '80s at work, a buyer thought that she'd save a couple of dollars per wheel and wouldn't buy what we had asked for. We were cutting slots in jet engine fuel nozzles and the cheap wheels would fail before a single slot could be finished. The wheels were supposed to be brass with the diamond coating bonded to them, what we got was cheesy steel disks literally (rattle-can) spray-painted with brass colored paint on top of the poorly bonded diamonds. There was hair & lint in the paint which kinda gave that away! In order to get what we needed, I had to actually write a detained specification for the buyer as a CYA for her to not buy the cheaper wheels. But we got what we needed, as far as those diamond wheels were concerned, from that point on!

[@bearsrodshop7067]

Young man you remind me of my self, and your thinking out side the box is awesome. I too over the pass 8 years have picked up free tread mills, and HC wheel chairs that open a whole new can of uses full worms. Love what you can up with for #roughcut2022,,,Keep on keeping on,,,Bear in TX. ps I am going to build an AC unit from a 12vdc trendmill 3.75hr motor for my 65 CJ Jeep, but thats months away,,,Will show on my channel when time allows. Great entry to roughcut2022!

[@624Dudley]

An entertaining build 👍

[@michaellinahan7740]

Jeremy, like you I used Stefan Gottswinter's design with those diamond discs but used a cheap 24v DC motor and a simple speed adjuster. I have longer side arm on the plate and on each side I have a fixed pivot and a slot for the tightening bolt. Mine is specifically used to 'touch up' carbide tooling or the parting blade.

[@ferrumignis]

Glad it's not just me that suffers the odd senior moment when marking stuff out/getting the wrong side etc. I think I would have been tempted to bore out the gear so the shaft didn't need to be turned down to a small diameter, although those sintered metal gears can be pretty hard. Very neat project though, essential really when you have carbide bits to sharpen. That parallel port switch case was a thing of beauty, you'd be lucky to get a modern equivalent in a thin pressed steel box these days.

[@FliesLikeABrick]

I love everything about this, down to the DB25 switch. Did you just happen to have the correct-sized large diameter reamers used for this, like for the OD of the plain bearing? Or did you at some point procure/appropriate the bearings+reamer as a bundle?

[@JeremyMakesThings]

I’ve got a pretty good collection of reamers, and it keeps growing. The fit on the OD of the bearing (1”) was a little loose, but….loctite.

[@N.Cognito]

Copper plating is commonly used to mask areas from heat treatment, your steel may have been a scrapped part from a manufacturing facility.

[@jamesolivier3192]

gear is probably soft enough to drill and tap for a set screw after that heat..

[@JeremyMakesThings]

That was plan b. 😆

[@kendingsor]

This went about as well as most of my projects #ifitworkitsawin

[@Man-in-da-shed]

As a rough arsed bodge it make it work type of guy, I can’t fault what you did, I suspect however there were a lot of in house jokes in there which you would have to be an engineer to understand, nay appreciate, but sadly above my head. Loved the vid though .

[@MarshallSmart]

Have you tried WD40 cutting oil? Comes with straw which is hand for drill holes etc. Good vid>

[@SuperGrover]

RPMs... Revolutions per minuteses? No offense, love your work. ;)

[@JeremyMakesThings]

I struggle with that one too, you’re correct, it’s already plural.

[@jimbayler4277]

@Jeremy M/T: What was the need to downsize the diamond discs ? As you built all the surrounds for the discs, why not use the discs as they came ? There were no space constrictions.

[@JeremyMakesThings]

There was a little height construction on the case I used, and I probably didn’t have a big enough piece of stock to make the backing plate for it at 6”. And for some reason, I wanted it to be a 4” grinder. But i did kind of wonder that myself.

[@jimbayler4277]

@@JeremyMakesThings : Thanks for the response. It was one of those little, unimportant, nagging questions that won't leave you alone until the blank information space was filled. I have carbide bits that will need sharpening at some point. So, I found your video very interesting.

[@dimitartenchev9338]

Are those Russian surplus grinder wheels ?
