    Finally made my first chainring

    I have been riding my Raleigh XXIX for 5 years and have wanting to make a chainring for it. I have all of the tools, but it has been hard to get around to it while keeping up with the regular jobs. I finally got one done this week. Took it for a spin this morning.

    It's a 33T to replace the one Truvativ ring that came on the bike originally.

    If you can make an attractive spiederless version, you could sell plenty.

    What's more impressive is that when he says he had the tools, he was talking about a single chissel and a smelting pot.
    I'm not sure how this works.

    A CNC chisel, actually.

    Do you do this for a living? If you can make spiderless rings for less than $50, you may have a new job and could tell the boss to stick it.

    Well, I am the boss already so...

    I am messing around with designs so I can add this to my website. I have been selling derailleur hangers for an obscure bike and custom emblems for VWs for a couple years. I have a bashguard that I have been testing for umm...about 10 years that I need to get up there too.

    A spiderless ring at that price should be no problem if I can sell them without a middleman. I don't want to get stuck in a spot like HBC, so I'm weighing what options I could make available to keep rings in stock and not have customers waiting months until they show up with pitchforks and torches in hand.

    Nice.

    I'd be happy to push the design hard if you plan on making a bunch. There's a lot of room for interesting detail there.

    Aluminum. This one is 6061 material that I had in my shop. I am just messing around with the design. I will pick up some 7075 later for strength and wear-resistance.

    Ran a lightweight version of the bash guard I made for my old Heckler 10 years ago. I switched that one over to my Blur when I got it in 2007. Now I have a shiny new one. I will have to send one out with the next batch of anodizing to make it look pro.

    I made a 32T ring for my Blur. It is super lightweight. I weighed it at the bike shop. I think it was 34 grams. I'm not sure about the strength, especially since it is made of 6061. I am anxious to get out and ride it. Rain is messing with me.

    Man... if you can design a 30T 104BCD chainring... the 1X and SS peeps will love you long time.

    I just did a quick drawing of a 30T 104 BCD chainring and found the fundamental problem with it. The profile of the teeth cuts into the chainring bolts.

    I thought so. I guess the only option with this is a splined sprocket and not a chainring.

    You'd need some different chainring bolts, but you can't guarantee compatibility across the board and you'd need to do some operating on the crank arm.

    Andersen Machine makes a 30T 104BCD right now as well, with supplied bushings and bolts.
