put the material your measuring with the calipers as far back in the jaws as possible. then rock the callipers back a forth over the flats on the jaws. the smallest reading is your measurement. easy peasy.
Hi, I'm planning to ream the seat tube of a vintage chromoly lugged steel road bike frame to accept a larger diameter seat post, specifically 26.8mm to 27.2mm, so ill be removing approx 0.4mm of material? correct? I'm planning to buy an adjustable hand reamer with a 26-29.5mm reaming range, the seat tube is already slotted so I'm planning on going as slow as I possibly can , the outer diameter of the lug measures approx 30.8mm, and the seat tube approx 29mm. Is this advisable? will there be enough material in the tube for it to be safe? in my head it works haha but id like an expert opinion before I go through with it, I'm doing this so ill have more options for seat posts. Thanks
It is possible to make oval headtube to normal?
Very cool video ^_^Question: can leaving that edge of material on the bottom of the bore cause it to interfere with a headset cup remover tool?
I wanted to put a modern 30.9mm seat post in my old aluminum Specialized MTB which originally came with a 30.8mm seat post. I used the adjustable reamer and flex hone exactly as shown here, and got a perfect fit. Thanks a billion for the tutorial!
great video, thanks a million
Love flex honing seat tubes on the lower end bikes at my shop. Makes me feel fancy lol.
Question. So Im trying to build my own bike out of an old mountain bike frame, but the headset tubes are 32mm and I have a pair 34mm headset cups. I can fix that by using a reamer? Just wondering if its worth a try
This channel is amazing. Thank you
Yes I like you work bro.
*I gather that the average consumer would never need to do these procedures, no? We may press headset cups and press-fit bottom brackets, but I assume that manufacturers do this for us, right?*
Drill a hole wider than the slot then cut the slot. Standard practice.
Since you have a milling machine in the background, couldn't you set up the frame carefully and then use a single-point cutting tool in a boring bar to do all these jobs, without needing all those expensive hand tools? (I guess it would be a pain getting the frame carefully aligned with the boring bar though.) The funniest thing I ever saw was a machinist in a big factory whose seatpost rusted into the seat tube and couldn't be removed, so the guy clamped his bike frame into a giant lathe with a 6 ft. diameter 4-jaw chuck, and bored out the seatpost!
Hey Joe: Can you post some information about the handle you made? I'm especially interested in how it clamps to the square top of the reamer. Thanks!
You should also watch how thick the metal is in the frame as you could split the metal. I also feel these video's are no longer DIY anymore.
When I used to finesse the seat tube, we had a light abrasive brush that we put on a drill and gave it a few seconds. Worked like a charm.
Glad I found your vid Joe, good work. It's six months later; how did the press fit pan out?
