Removing squaretaper crankset w/o threads

I'm trying to get the crankset off a Specialized Allez Triple from 2004. Left arm came off without any problems, but after removing the bolt on the drive side, I found that the righthand crankarm haven't got any threads. They're not stripped - it's apparently made without. I've tried using a plastic/rubber mallet and the thing won't budge. What would you do? HTFU? Try using a flywheel puller or something similar? Am I missing something obvious?

I've had success removing with a block of wood and a hammer, and working around the crank. I've also tried another method of loosening the bolts (but not completely) and riding the bike about to get the crank off. The idea being that it comes off but is safely caught by the loose bolt. This didn't actually work for me though!

Yeah, I know the ride-it-'til-it-falls-off-approach, but this is a stripped frame and I'd rather not build it up, just to get the cranks off :) I've made a plan for tomorrow, where I'll make a puller from 6 bolts, 6 nuts and a piece of wood.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
