    Some time ago, I started looking a making a solid grinder that took a C-face motor to reduce alignment issues and had some mass and could be assembled without any welding. I took some concepts from the EERF and other grinders and made a grinder in AutoCAD.

    My buddy Darrell at Water Jet Ltd. in Edmonton got the job done.

    When the pieces came home, it's time to tap some holes, grab some bolts and really see if this is going to work. Computer to reality doesn't alway work 100%

    [​IMG]

    There's a little bit of tapping. Last count was about 15. These range from 10-32 to 1/2" NC.

    Unlike the EERF this will be a horizontal and vertical grinder.

    It's still being tweaked and I am waiting on some parts to come in. As soon as I get the base done it will be ready for paint.

    The CAD files will be free to download of course. And anyone who makes alterations or new features can have their files posted for others to use.

    I'll keep everyone updated as the build progresses.

    Wow that's looking top notch. As a millwright by trade I take pride in the ability and the tools I have to make my own stuff. And for people like yourself that have these awesome ideas and plans and then to share them haha it helps out so much! To have someone do this plan up would be a lot.. thanks and great work so far!

    Thanks John and Parker,

    I know there are three tiny mistakes in the CAD file so far and they are all from me using the wrong holes sizes. I wanted to tap for 1/4" and I copied and pasted a hole that was for a clearance 1/4". So I had to tap it to 5/16". Once all these are sorted out I will offer the files for public consumption.

    I am a 2D only CAD guy and my software is from 2007, but you don't need anything fancy to cut some steel. Hopefully, some CAD whiz can take the 2D and make a sweet 3D version.

    I envision a repository of files. Essentially everything one needs to build a great grinder; CAD files, videos, photos, wiring diagrams, how to guides, programming for VFDs, jigs, attachments, charts, tables and anything else that is relevant; both metric and imperial. Of course everything will be free to use. Like great open source software, the whole collaboration thing leads me to want to call this the Open Source Grinder Project. I am testing out some plug-ins on the hosting plan to see what can be made useful.

    Stay tuned!

    Dan,

    That is awesome.

    What can I say you are an amazing person. Your continuous service to the knife maker community is incredible. Next time am in town I have to buy you drink.

    Have you named it yet?

    Still working on a name. Any suggestions?

    How about Starfire Godiva?

    Well, "Starfire Godiva" is interesting. It will be nice to acknowledge the work you are putting into it. So I will suggest "Starfire Godiva DC" or "Dust Maker DC". Others may have other suggestions.

    Once again you've outdone yourself. That is a sweet looking grinder. I just may have to try it out as well. Off the top of your heads, does anybody know what it would cost to have something like that cut out?

    Really cool Dan.

    Starfire reminds me of the Starforge from the old Knights of the Old Republic video game. So, i'm all for it. But I agree that it should have your initials.

    Actually the Starfire Godiva was a bit of a joke.

    The open source idea lends itself to not being owned by anyone. I am thinking the design would morph over time and having my initials on it would seem a disconnect from the original build. Still looking for something cool. Suggestions appreciated.

    Todd. it depends on who you know. Laser or water jet would work equally well. They usually charge by table time, so thicker materials and more cutting obviously costs more. Sometimes they have a minimum setup charge then so much an hour. I would budget CA$400 for steel and cutting but you could probably swing a deal if they are not terribly busy. When the CAD file is out, shoot it to a few places on their email and ask for their best quote. With a quick look at the file, they can tell you how much the table time it will take.

    awesome. THanks Dan. And, my sense of humour is so offbeat that I often mixup serious and joke. I'm a bit odd that way : )

    Ah the name thing has been bugging me.

    I thinking...(err make that drinking) last night and came up with this. What do you think?


    [​IMG]


    I was looking for a unique name, that's easy to say, sounds cool, with a hint of sharpness and danger.

    Me likes the name. I have been following this closely. I think I know what I will be building when we get the new house. Thanks for making things easier for us that don't really know what need to be done.

    Cool name. Like it a lot. Gotta have the word "project" in there if it's open source. Just sounds right. Love Sayber. What about Sayburr, like burr on the edge of a knife. Too much wordplay? Anyway, you're making me rethink things. Especially if there was some kind of sticker or brand plate i could attach to my Sayburr OSG (nudge, nudge, wink, wink, say no more...) : )

    Also, it looks cool sometimes when they captilize the second syllable. LIke "SayBer" (or "SayBurr" if that's still on the table ; ). My company does that in their name and its' kinda cool looking.

    I think Sayber or SayBer fits all the bills, could be a brand name, or a last name with a nice coincidence, and points to the sharp edge that it is capable of producing.

    Todd, this is the nameplate I came up with.

    I like the name (SayBer) and the nameplate. It will be nice if the nameplate can be printer on a metal (aluminum or.....) and riveted on the SayBer.

    Got around to applying some paint to the pieces before assembly. I went with this product from Rust-oleum that I found at Home Depot.
    It's supposed to have a textured "hammered" finish. I cleaned all the parts with acetone and painted them. The instructions call for a second application after 30 minutes to 2 hours. It's on the second application that it takes on the textured effect.

    [​IMG]

    First coat is a regular, but slightly orange peel finish.
    [​IMG]

    The second coat brings out the hammered effect.

    I must say the paint is really good and covers well. Allow at least overnight to dry. I'll start assembly after everything is dry and the threaded holes are chased.
