I like that cable stop holder. I just use a broken foil blade (the square edge fits the slot, and the diameter is small enough for loops) and my trusty piece of bent tubing.

Hey all- I've read this thread but have been too distracted to get my photos collected. So here's some of my bits. First are the cable clamps. Second is the water bottle boss alingment brazing jig. I still do the holes freehand but can't stand crooked bosses. Third is the DT gear cable stop jig. I make my own stops and built this jig to match final specs. Fourth is the BB cable guide brazing jig. An example of my over doing things. But it has worked very well for 15? years.
What is neat about thread is the similar but different nature of the tools. I am proud to say I influenced one that's been shown. But the poster added a change to his iteration, a much better tool resulted. When I redo my version I'll follow his new lead.
This is a good post, but, while I can make tools, I don't know how to upload photos into a post the way you guys do.

manage attachments, you get a window, upload, and then insert inline.
When one has a small frame that has the two head lugs touching I like the appreance of flowing head tube points
with tangent top to bottom shore lines
I have a 31.7 cut out HT in the tool drawers
and these pics are of a 36mm HT I did yesterday as I did not have or expect to ever require a 36 mm tricky cut out head tube
but you never know
as this punter wanted and asked for a stiff frame with XL tubes.
So the pictures should tell the story
and then the rest of the lug shorelines are sweetened to one's taste in the normal ways
I just noticed the wiki, and I'm surprised this thread isn't in there yet
Dazza that's one of those palm-to-forehead things that is so obvious it actually takes someone really smart to figure it out, awesome.
DT holder for tacking.
I recognize that! got a couple myself.Quote:

Here's a little thing I made to hold pump pegs, but use it for lots of braze-ons now:

This is my rack holding jig. This is actually a rack I built a few days ago and I only use the jig until I braze the first legs onto the base -- in this case, the ones to the brake bolts. Then I pull the jig out of the way to finish the rack.
Attachment 21319
Holding the lamp bracket was a hassle until I just clamped the vice grips to it and swung the fork with rack in the Park stand until I had the bracket where I wanted it. After it's tacked, I can remove the vice grips and finish brazing.

Heres one I've been meaning to build for a while. It's raining and a holiday so its a good day for it.
5/8" set collar, 3/4" cold rolled and ten minutes.
a simple tool or fixture might just be a M5 Caphead and two nuts
a simple little fun thing yesterday that helped break the toil
tis a frame for a bloke I raced with 25 years ago
Cute little casting eh!
How are you turning that facer? If you're doing it one handed that has a tendency to lead to the faces not actually being flat. Taps and facers should be turned evenly with both handles.Quote:

The mandrel is an offcut from a length of redgum fencepost I found in the woodshed. I cut, sanded and planed it to a constant radius and then routed a groove down the middle. For those of you not familiar with it, redgum is a fantastically dense and hard eucalypt which proved to be just about idea for this.
http://i182.photobucket.com/albums/x...nder_clamp.jpg
The fork tip clamp was knocked up out of some steel offcuts in the scraps bin, and is anchored by a pair of M10 cap screws that are threaded into hexagonal threaded rod couplers. The wood block is grooved to match the fork tip. Note the pint-sized bottle of Little Creatures - perhaps the finest beer in my world.
http://i182.photobucket.com/albums/x...ender_stop.jpg
At the other end of the lump of wood is the bending stop. This is another M10 bolt and rod coupler, and provides a repeatable way of raking fork blades to exactly the same point.
http://i182.photobucket.com/albums/x...er_widget1.jpg
Doing the actual bending itself is this little doohickey. It's a short length of 25mm angle, with a bored out 1/2" nut brazed to it. The nut pivots on a 1/2" bolt that pierces the bending arm. It all looks kinda Soviet era agricultural, but damn me the thing works. Effortless, repeatable and consistent bends. Total cost was about $10 spent at the bolt shop. Everything else was already in the parts bin or was scrounged for free. I'm pretty happy with the results.
If the definition of "Simple Tools" is wide enough to encompass laser alignment, I guess my method of gauging braze penetration will be of interest. The instrument is a Nova 800 precision thickness gauge I bought second hand on Ebay. It's an echo - echo ultrasonic gauge with a facility to input the propagation velocity of the material in use. These were very expensive new but the latest Nova TG110 is now under $1000 and does everything you are likely to want. My unit was designed to work in inches but I have tweaked the display to show thickness in cm (all you have to do is multiply the propagation velocity by the appropriate factor). The transducer is quite happy with curves, I use it to measure wall thickness on tubes and stays.
The phots are of a test piece - two strips of approx 1.1 mm 316 stainless sheet silver brazed from one end. In phot 1 the transducer is over the brazed section so it shows a thickness of 2.35 mm; in phot 2 it's over the unbrazed section so it only shows the thickness of the top strip.
I'm still a newb, but I like building widgets, too.

None are perfect, but they work for my needs.
This is a boss jig I set up from a pedros clamp.

I'm gonna bump this hard; I'm sure there's more out there to share. The homemade fixtures are just the best.
I'd contribute if I had anything of real value to add (look! angle steel AND a three-way c-clamp!)
When it's time to change hole saw arbors for a long cut... I curse those little buggers. So I used some "strategery" and made this little lever arm. Threaded on one end to accept a knob, and a filed groove to locate into place at the hole:

My brake post jig. I have a collection of arms that are drilled for various post locations and make new ones as needed. For forks the Vee block thingie goes under the dummy axle, for posts on the rear end it goes above.Attachment 75954
I have noticed a lot of fatigue and cramping in my hands when filing fillets. A large part of this is the result of lousy handles. I needed something more ergonomic and ball shaped. I aquired some walnut and turned these.

This thing was meant to be a lug vice. I think I've used it once for that - I don't do much with lugs - but it's damn handy for other things, like pushing out this big dent in a head tube:

I made a few of these simple lug vises.

I made this little ditty today by welding some threaded bits concentric with each other in a v-block. Thread the DT shifter bosses until they snap onto the DT and the bent rod acts like a spring keeping everything where it should be. I was going to mill something out of scrap aluminum and reeled myself back by checking this thread. The simplest solution FTW.
