    A Vintage Parts Fab

    If you can no longer buy it, you end up making it.

    Very nice,

    That's an expensive little part there in machine time eh? 3 hours or so......
    Makes it about a $300 - $400 part

    1.5 hours. But yes, an expensive little part, especially when you consider the investment in machines.

    So, are you going to anodize it 3DV?

    ssmike, if you owned a few GT's you'd know what this was for. ;-)

    Looks like the top of a flip flop stem? If so, I never would have gone to the trouble. There are people that have them in NOS for $9.95-$11.95 maybe not the right length though?
    Needed: 26.8mm XTR seatpost, blue GT/Grundig Jersey.

    Actually, I don't own any GT's either, thus the ";-)". But I suppose it would work on a GT.

    Where is such a part available NOS?

    What do you mean...I stamped the "MAX 22mm" line myself and ribbed the bottom expander. This is serious reproduction work. ;-)

    Working on too many carbon bikes and disk brakes?

    GT Flip Flop stem from 1991. They are commonly available on eBay for as little as $9.95-$15.95 but are always black. One seller has both 1" and 1-1/8" listed in his store quite often. Stop turning and start buying

    Those are a dime a dozen too. Some of you guys need to learn to use google.
    ferrule end-cap cadplate 6mm 10 pack ... $4.99 More common in motorcycle shops these days then bike shops.
    There's also a ton of old Tioga 2.0mm innerwire brake cable sets out there that come with them.

    Good to know. However this part and the 6mm ferrules are destined for a very specific application, for a bike as early at 1983-1984. More to come.

    Nice work

    I always love to see machined parts, even if it's something simple. Are those sausage links for dirt drop shifter mounts?

    Keep the pics coming.

    Maybe we should make this the official thread for repro parts! I have a few I could share, but nothing too vintage or exciting. I teach machining for the local tech college, so I am constantly coming up with home projects for my bikes!

    Dirt drop shifter mounts would be highly desirable whether they were for the standard XT thumbie, or maybe a new style that would bolt right up to a set of vertically mounted 970 XTR trigger shifters. Unbolt the original xtr alloy clamp and bolt the new one on. I have dreamed about this part for some time... .

    Nice work on all the parts!!!!

    Not fair to show off goodies like this and then not offer some for sale to the members here.

    I also understand its a freaking pain in the neck to get stuff made in the first place. not cheap and time consuming.


    bravo !!! good job!

    Nice setup!

    Love your shop, small, neat, and just what you need!

    I tried the dirt drop mounts for XTR Shifters, but mine didn't turn out so well. I actually sent them to someone on the boards, but never heard back how they worked. I love to look at parts on my bike realize, hey, I could make that whether it's something VRC, or just a normal part. I have a schwinn cruiser that has a bunch of parts I made for it. Lots of fun, and I always like knowing I made part of my bike.

    My next goal; learn how to weld and make my own frame!

    Keep the pics coming, I will dig some up when I get back to school next week!

    OK, if you're talking about the angled plastic cap that presumably cracks, that's not easily replicated in metal because of the angled lip. At the moment I can't think of any way cheap to actually make that.

    The Syncros cap I have on an early 90s threadless stem is made of metal. Looks like magnesium?

    DoubleCentury,
    Sorry, but I'm going to have to call you out on this one. There is no way in hell you could have made those parts in your shop because I see not a single metal chip on the floor, the milling machine table, or even in the chip tray of the lathe.

    Hell, I wish my kitchen was that clean most days!

    Now, as a machinist dork and manufacturing engineer who makes bike parts daily, please tell me about your Hardinge lathe. Not sure if I recognize that one.

    Nice work, BTW

    Every shop is new for once in it's life...and I keep mine clean.

    The Hardinge is a T-10, the predecessor to the HLV and HLV-H. It was built in 1942 and issued directly to the US government through the Defense Plant Corporation. The lathe was a mess when I got it and was missing the tailstock, so I made one from scratch. The restoration took a year.

    The looptail was an NOS Yeti Ultimate I sold some time back. The story appeared in the Sunday Times,

    We talked about these caps somewhere else here on vrc.... I would try emachine.com.. draw it and get quotes. The metal ones are Al.

    An option that may work, and ease machining would be to sleeve and braze two different parts together. I don't have a stem to look at.. avoided them like the plague.

    After seeing what you are making I'm assuming that none of that stuff is available any longer commercially. Or you probably wouldn't take the time.

    In the old days before many others had done it I made adapters to mount thumb shifters to drop bars. They looked a lot like yours. Then someone started selling adapters. WTB I think. I never bought any because mine worked fine and eventually I made my own bars that eliminated the need. But lately I have been thinking of using drop bars again just for fun. So does anyone still make shifter adapters for drops? Paul Thummies look like the only work on small dia flats. Also that quilled steerer stub is key if you want to run an LD stem with 1" threaded. Anybody sell those? I've seen 1" to 1 1/8 stubs but they are always sold out.
    No it never stops hurting, but if you keep at it you can go faster.

    As you mentioned Paul's makes a road thumbie for 26.0mm bars, but they are really only good for mounting on the top of the bars which for me would not be workable when riding off road. Kelly currently makes the Take-offs as well:
    http://kellybike.com/2nd_xtra_takeoff.html
    This is actually closer to the original WTB design, but using upright down tube shifters like that reminds me of the 70's when they came out with the stem mounted downtube shifters. Seems like a more road-oriented shifter mount than an off-road solution but maybe you can use the Dura ace bar ends on the Kelly take offs in an inverted configuration? With the increased movement of drop-bar mtb's and Montsercross bikes, this is a opportunity waiting for a solution.

    Yep, works great and pretty much the same cable pull as most any drop bar lever.

    As for STI shifting mechanisms being fragile, no way. Super durable. Same as Rapid Fire.

    110%. Would way rather run STI than these bolt on workarounds...it's one of the good things in life.

    The looptail was an NOS Yeti Ultimate I sold some time back. The story appeared in the Sunday Times,

    LOL!

    Fear no competition here. I'm just an amateur with a day job.

    Besides, I submitted a brazing job to Taj Mahovel not long ago.

    Shop rate

    Not sure about other parts of the country, but shop rate here in Utah is around $80 an hour plus tools, materials, etc.

    It always shocks people how much non production machine work costs. I have people come into the Tech College where I teach looking for someone to make "this simple little part" for them. They always choke when I tell them what typical shop rates are.

    Just one of the small perks of working at a tech college!

    Hey Jacquie P, that was some time ago when I was standing around on the job but I do still tinker in the shop to make parts that I can't find or if I see a fellow biker in a pickle to get his/her ride back on the dirt. Shop rates are "who you know" rather than the standard 80 bucks an hour. Of course trades are always welcome by the guys who have access to machinery.

    Fun to see anyone like me does make his own bike parts, I do have a well equipped shop too.

    It´s a big peace of mind to make his own stuff and use them.

    Take a look of my creations:

    I sent the link to this thread to Charlie Cunningham, thinking he might enjoy it, and he did. And he responded with some wonderful home-grown engineering of his own. I asked if I could share the notes and pics he sent and he said sure, but stressed that the pictures were just quick snapshots and that parts he made were "quite industrial, but function quite well." How cool is that?

    Hi Dave,
    Thanks for the info. I'm always interested in what avid bikers are up to. I needed a pair of flatbar friction shifters for one of my bikes a few years ago and couldn't find anything I liked so I made some that bolt onto the brake lever. They have a nice cable pull ratio, meaning the levers don't need to be moved very far to make a shift. I've refined the shape of the part where the finger and thumb grab them to get all the shifting characteristics I want. (I used bondo which is light and the shape is easily changed/modified.) They work great and produce reliable, accurate shifts. I took a few pics a minute ago with Jacquie's camera and will see if I can get her to email them to you.

    Charlie










    Here is more clarification about the levers:
    Hi Dave,
    I'm fine with you sharing the pics but upon seeing them I'd have to say most of them are pretty crappy. But at least they give an idea of what's going on. Each shifter barrel has an adjustable friction setting that can be locked in position when the friction is just right. The arms are M5x0.8 cap screws and the core of the finger blobs are made of magnesium with set screws that mount them (adjust-ably) on the arms. Overall look is quite industrial but they function very well.
    C

    Speaking of making what you can't get, I have decided I must have some stock to cut myself cassette spacers to size as needed. Aluminum rod was my first thought, but maybe PVC is a good cheaper/lighter option? One size I want is some 0.2mm spacers (index shifting w/xc pro thumbies and shimano 6-7spd cogs) so perhaps PVC won't hold up this thin? Anyone have/know where I can get a few feet of 42mm OD 39mm ID tubing?
    Side note I have just discovered this forum after years of lurking on MTBR and y'all are AWESOME!
    Charlie why dontchya paint that bondo if it's aesthetic is bothering you? Still hate paint?

    10spd is for chumps

    Inspired

    After looking at all DoubleCentury's work, I was inspired to revisit the dirt drop shift mounts. I bought some shifters a while back, but forgot I had them. Not XT or XTR, can't afford those!

    Should work this time!

    Mounted...

    on an Origin 8 Gary bar, cuz my Woodchipper is currently wrapped, and I don't have any of the original WTB bars.

    Looks promising

    BTW the marks on the bar are from an earlier experiment that didn't work so well. The clamps I have are shimmed, as I don't own the WTB modded towers/clamps either. These are suntour towers with some clamps I bought from Loose Screws to try.

    This is the initial mount up, haven't even put them on a bike yet. Personally, I don't like the Gary bars, the drop extension is way too short. These will be destined for the Woodchipper bars on my DB Overdrive.

    I only mounted them up to these bars to see what they looked like. The position will take some tweaking, but I didn't want to unwrap the other bars until I was sure they would work.

    I will have to fiddle with them quite a bit before I am satisfied.

    I like it! That may be the ticket to making them feel right. Luckily, that's an easy mod!

    Are those the original DKG mounts? I assume you made the extensions? I would love to see the plans for those. I think the hole pattern for the shifters I have is different than the XT/XTR. There seemed to be no rhyme or reason to it while I was reverse engineering it!

    Glad to see I'm not the only one who is constantly tinkering w/bike parts!

    BTW DoubleCentury, what do you do for a living? Just curious how you got into machining?

    Yeah, isn't that great? Of course, Charlie Cunningham still makes incredibly well-finished bike parts too, like the lever-link brake on BMC Mike's bike:
