Making a headset & BB cup pressing tool for $10. The "How To" thread.

Got $10 and want to make a simple tool that will save you from whacking a 2X4 block with a hammer to press in your headset and bottom bracket cups? I did, and it was worth every penny.

Here's what you'll need to get started...

1 - 14" length of 1/2" thread "ready rod". This is available at any Home Depot in lengths of 36" and are easy to hacksaw down to size. 14" is more than enough length, but I like to have extra to be safe...
2 - large 1/2" washers
2 - large 1" washers
2 - long 1/2" nuts
1 - 1" threaded headset (well, that's what I needed anyways...)
1 - frame needing cups pressed


http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_1.jpg

I also highly recommend getting a tub of this. It's about $4.00 for a tub. (The Budweiser is entirely optional)


http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_3.jpg

A good rag to wipe the excess grease from your hands and a couple of wrench's round out the hardware required.

http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_4.jpg

Before we get started the tool will set up like this... Each end of the ready rod (from the outside in to the center) will have the long nut, the 1/2" washer, and the 1" washer.


http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_2.jpg

First, grease the inside of the top (or bottom. Your choice) of the head tube liberally with the Castrol MP grease.

http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_5.jpg

Next, fix the nut and washers into place on one end of the ready rod and slide it through the head tube until the 1" washer is against the end of the bottom of the head tube, like this...


http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_6.jpg

Slide the top headset cup down over the ready rod and into place on top of the head tube.


http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_7.jpg

Affix the other washers and nut into place above the headset cup and tighten it by hand until snug against the cup. (Sip the Budweiser if you exercised it as an option, like I did)

http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_8.jpg

Hold the bottom nut in place with one wrench and tighten the opposing nut with the other wrench until the washer pushes the cup tightly into place.

http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_9.jpg

For the other cup simply "wash, rinse, and repeat" the same thing you did for the first cup...

http://i101.photobucket.com/albums/m80/Triumvirat73/Cup%20Pressing%20Tool/headset_tool_10.jpg

Stand back and smile at the pretty new installed cups.

I hear ya guys. I just figured there were probably a few folks here that might not know about it and this may save them an unfortunate slipped hammer mark or two. wink

Re: Making a headset & BB cup pressing tool for $10. The "How To" thread.

I've found that a 1lb ballpeen hammer and a couple 2x6 oak blocks work just as good, if not better.  Remember, allthread is typically real soft and can stretch or break pretty easily.

Re: Making a headset & BB cup pressing tool for $10. The "How To" thread.

You get 2 rods out of one 36" length, so at $2 a rod I think it's a much safer option personally, even if a rod doesn't last forever. At least a person is guaranteed not to slip a hammer, or misshape a cup by driving it in unevenly.

To each their own, and I'm certainly not knocking your method. I just figure it might be useful to provide an option for people like myself who are uneasy swinging a hammer around a treasured frame. wink

Yeah, you gave me a sweet deal on that. $300 I believe. I'm just getting around to building it up now. (maybe one of these days I'll actually get off my arse and send you those 401 arms to get chromed eh?) wink

Cheers bro! big_smile

Re: Making a headset & BB cup pressing tool for $10. The "How To" thread.

That's very kewl, and a great tip. I used my big bench vise (with wood scraps inbetween) to press in cups and sealed bearings, but I'll probably pick up this hardware as an alternate back-up. Thanks Greg!

I dunno how the experts to it, but I clamp the frame in my bench vise (with wood between the metal surfaces), and use a big old screwdriver that was already damaged and a small sledge. I stick the screwdriver through the opposite side of the frame where the cup is, hold the tip tight against the bottom edge of the cup, and whack it moderately. Then I'll move the screwdriver tip to the opposite side and give it another whack. Most cups come out within three whacks or so.

Just don't overtighten the frame in the bench vise. I guess some fairly thick leather or firm rubber of some sort might be advisable if the frame is show quality or something. Usually when I'm removing cups the frame is already in bad shape and about the be repainted anyway. Just my 2 cents.

Right weight for the application, use the flat side.  I've done lots of bearings and cups on for many different applications with a hammer and block of wood.

I guess it boils down to what you feel comfortable with.  I don't like using allthread, since I have seen it fail numerous times.  But everyone has their own methods.

For cup removal, I use a large 5/8" brass drift and the same hammer, just rock them out slowly with fairly light hits.  I hit in 5 spots, using the same pattern as tightening up a 5-lug wheel on a car.

Re: Making a headset & BB cup pressing tool for $10. The "How To" thread.

Word, Greg.

I JUST made one of these earlier in the week for another Standard build I just finished up (will post pics later, heading to the pool with the kids now...). Anyway, this works great, on both 1" and modern headsets as well.

As for removal, I found this method of using a piece of copper pipe, cut vertically, splayed out just like the headset removal tools the LBS probably has... http://www.instructables.com/id/Bicycle … p-Remover/ Pretty rad site for general "how-tos" as well.

I USE AN OLD FORK THAT HAS A LONG TUBE AND JUST TURN IT OVER AND SMACK EM OUT BY USING A HAMMER AND HITTING IT WHERE THE DRILL HOLE IS FOR THE FRONT BREAKS. THE FORKS OFF OF THEM SCOOTERS WITH THE LITTLE MAGS WORK GREAT THEY HAVE THAT SUPER LONG HEADTUBE.

DO NOT use an old screw driver unless you want to damage the cups. Use a piece of brass stock, and hit that with the hammer.
