Price seems a bit ambitious for a housemade grinder kit.

Generation 5 Revolution 2x72 Build Kit

The Revolution 2x72 was designed with the home builder in mind. The novice fabricator can put this together and have a versatile, feature-rich, tilting 2x72 Belt Grinder that would cost thousands of dollars if it were manufactured. Get the Ultimate Bundle Kit and see how you can Revolutionize...

Those kits are without VFD’s or motors. If you add that stuff, it’s likely another 6-800 Canadian. And that’s if you find good deals.

I built Jer’s grinder, 2 of them, for about 1350$ CAD a piece….. and I have access to commercial pricing on electrical materials….. and on laser cutting, and I scrounged and used some recycled materials I already had, using my lathe/mill to form.

The hausmade kit is 1000$ us, plus the 6-800 spent on electrics, is like 2400$ ish Canadian.

He’s high, but not by as much as you would think.

2x72’s are expensive.

I was looking at building Jer's 2x72 after seeing his surface grinder attachment. I had no idea they were that expensive to build.

I could have maybe saved 100-150 by not getting the plate pieces laser cut. Per grinder. You can save a lot if you do a single phase motor instead of a VFD….. but that’s lame…. I also used a 2hp motor, so bigger then some say is necessary.

I think I spent on the wheels like 180$, you could maybe save some money if you made them from bar stock… but that’s a crap ton of lathe work to save 100$.

I made my own DOM tubing instead of purchasing because I have solid bar laying around.

I went through 100$ in gas and probably 40$ in welding wire throughout the project….

So maybe bare bones single phase no laser cutting and build you own wheels you spend like what, 750$ cad?

I do not regret spending the extra 600$.

Jer budgets like 700$-1100$ USD for his grinders in his plans.

Considering that, I did it CHEAP for what I got.

I figure I'll be into mine for around $500-600, only counting material. Sitting at around $300-350 now (rough guess), but still need to buy some hardware and stuff like a 10" contact wheel....I still have also not bought a VFD and will use my shared one (I use same one for my Mill, shaper, and surface grinder) for the moment, but plan on buying one in the future as the money tree regrows. It's my own ground up design, but is based/inspired by Jer's tilting hinge idea. Of course I'm not counting the labour, or the amount of times I've flip flopped on major design changes.......If I did, I would have been better off buying the one in the link........

I thought I was all good to go out and start cutting my hinges and other parts out today, but I came up with another "brain wave" attachment idea this morning and started making changes to accommodate for it again.....I'm pretty settled now (I think, I hope). The new idea made my old tension arm obsolete, but there's lots of room there to figure something out later, and in the long run I'll be better off going this route. But I'm currently under a cat, and I don't want to run afowl of international cat law again......So I'll just sit here and finish modeling some stuff.

Of course I need to take a side quest #3 (or is it #4 or 5 at this point?), and make a tooling plate to hold the flat stock before I can start cutting out my plates and other CNC stuff.......

I was very tempted to try out https://www.cutmyparts.ca/ last week for a few things instead, just to give them a try and get it done, but I already have all the material here, and a CNC I just spent a lot of time and money fixing and getting ready to use again the past couple months, so......the wallet is closed for now.

You have a motor as well or no?

I spent 550/ea on steel alone for mine. Laser cut.

If you have a motor, you are getting steel at like 1/4 the price I do

Yes. Bought the motor years ago at an auction as part of a hydraulic power pack for around $40-50 (can't remember exactly).

As for steel, I buy a lot of mixed bulk deals of drops and offcuts from my local steel yard for around $0.5/lb. Usually he bundles them on a pallet for around $250-500 depending on what they are, and I've probably bought 6-7 over the past few years, and split a couple with an old coworker. My investment in my own "stock market"..... They're usually a nice mix of sq/round tube, flat plate, sheet (sometimes) and solids but the last one I bought was qty44 2"x1/4" wall square tubes about 60" long. Nice clean new steel. I usually design my projects around what stock I have from those buys, but will buy new occasionally if I need to. That last buy of tube contains the carriage for my sawmill, a log arch, my new welding table base, and a few other projects like some parts for this grinder whenever I get around to it all.....

I am a cheap scrounger and habitual classifieds browser.....Almost always the biggest driving factor behind anything I build is how inexpensive can I make it for lol. The design side is also one of the most enjoyable to me also, so I don't like buying plans for stuff. I'll take ideas from many sources, including my own, but I generally dislike following plans, and would rather come up with my own designs for stuff as I find the creative freedom very enjoyable. The downside to that is that it will sometimes take many months/years to accumulate enough pieces and parts to complete something, and builds go through many stages of completion but for me that's half the fun of it all. If I actually need something NOW, I'll buy new, or pick it up on marketplace, but with enough hobbies and interests, that's usually not the case. I'll just move on to another project until I scrounge enough parts to move something along a bit further. I think I bought that motor for mine back in 2013. And a pack of mixed belts from canadian knife supply back around 2016 that are still in the box.....so ya, this ones been on a the burner for a while :D. I'll get there eventually.....Life gets in the way sometimes too.....
 
Geeze the last one I built might have cost me 200$, wheels 80.99 on Amazon, used single phase 3/4 HP jet pump motor 50$, switch 10$, msc hardware 20$, steel I had, but if you were to buy it, maybe 100$

You can spend as much or as little as you want, new motor is going to cost, high end vfd $$, it can add up quick

The first one I built might have been closer to 600$ with a new motor and at the time wheels were quite a bit pricier

Dan, is this something you are designing? Interested to see what you come up with. There are so many feature-rich designs out there I'm not sure what I'd even want in one .... so I'm looking to you to make sense of it all for me :)
Click to expand...
Yes, been working on the design (on and off) for years but only recently started getting serious about actually building it.

I'm not really sure what I want in one either, which is why I keep adding and subtracting stuff from it :D. At many points along the way I've thought about just building something simple, quick and easy, but where's the fun in that. This one is about the journey, not the destination for sure....

I have a few pieces made so far, but really no progress to show yet. Once I get a bit farther along I'll start a build thread, instead of just burying stuff about in my catch all shop ramble thread.

I have my material too, but I think I'll get a quote to have the main plate cut...

Aside from the cost, one of the things that holds me back from building a 2x72 is effective dust collection. Has anyone seen a good setup for containing the mess?
Click to expand...
That's one of the things I'm trying to incorporate into mine. Dust control always seems like an after thought, and not all that effective. I want something integral from the beginning but that is turning out pretty difficult due to the tilting nature of my design, but I have some ideas around it. Ironically, I'll probably just build it first, and then work on the dust collection afterwards lol. You know, as an afterthought.....D. I'm trying to incorporate some stuff from the beginning though, so I don't build myself into a corner, but the actually dust control part will certainly come later.

I've been toying with that idea today too. The most recent change I made was from a foot mount, to a face mount, and the only material I have big enough looks like it has spent a decade sitting on a barn floor (because it has). I know a motor mount is hiding in there somewhere, but I'm not sure I want to put in the effort to find it.....

I'm going to upload some files to https://www.cutmyparts.ca/ later tonight, and make a decision.

David, Do you still have that place out by you that was cheaper than my sendcut send parts last summer?
