Threaded fork question
So I finally found a 1" threaded track fork. But the threads don't go down far enough. I need another inch of threads and it should fit fine. When I took it to the LBS they said they wouldn't do it because it would destroy their tool. Has anyone here ever had threads cut into their fork before. By the way, the fork is NOT chromed.
Thanks.
Thanks.

Find the old shop with the retro grouch in the shop. They will have the good old tools and know how to use them.

The shop did not want to do it because they had a "thread chasing die" which is designed to clean up damaged threads and not a "cutting die" which is designed to cut new threads (these are made of harder tool steel and are more expensive).
It is true that cutting threads with a chase die will eventually ruin the tool.
You can call other shops to see if they have the proper tool or buy a cutting die for about $80.

Strange that the LBS only charged $10 to do that. Unless they have a large, bench mounted machining tool, cutting an inch of threads probably caused a lot of wear on their tool. A cutter such as the Park Fork Threading Set FTS-1 is typically used for chasing threads or adding a couple of mm, not extensive cutting. Maybe your shop replaces dies a lot or doesn't do this process often. Those tools are pretty expensive.

They're probably not cutting a ton of new threads all the time. Besides if they use cutting oil properly, I'd imagine they could cut new threads or chase threads for more than enough customers to make up the cost of the tool.

What you should really do is use the right fork, and only resort to cutting new threads if it is impossible to find one that fits as-is.

Plus the squealing sound the die makes while cutting is like fingernails on a chalkboard. I'm surprised they didn't charge extra for making all the wrenches in the place endure that

Thanks. I found a place to do it. They cut the threads, charged me a bunch, and my bike is rolling again. Too bad its -6 degrees outside.

Someone was selling it on the Old Skool Track message board. Its a Croll track fork. No brake hole and interesting lug. The fork was yellow when I got it, and said "Croll" down the sides. I colored the bottom black with a Sharpie. Hahaha. I'm painting it for real once it warms up a little.

You can even get threads cut into chrome if you have someone who knows what they're doing. I had a chromed recumbent fork I needed to add threads to . The guy (an independent who works out of his house and knows more about bike wrenching than all the LBSs put together) sanded the chrome off first then cut the threads. Wasn't cheap. But cheaper than a new fork.
