Square tapered crank removal without tool

Does anyone have a suggestion in how to to take cranks off without puller tool? I have ordered one on eBay but It seems to be lost in the mail and I need to move along with my project.

Other methods exist, such as those employed when the extractor threads in the crank are stripped.

Square taper crank stuck on spindle, crank removal threads stripped

But, you still may need to hunt for a tool.

Any options that dont involve the tool will be a significant PITA. The Park tool should be like $15-20 at a bike shop and is significantly nicer than the generic versions I've seen. Its really worth going and getting a Park.

"Need"? Then take it to a bike shop.

I now own a proper crank puller (Park Tool CWP-7 on Amazon for $14)
Before that.. I tried a pickle fork (carefully because I did not want to ruin the crank) and pounding a wooded wedge cut to resemble a fork which worked on the chain side but not on the non chain side..
I cut a slot in a square piece of metal, slide behind the crank arm and used a two prong gear puller. Wasn't pretty but it worked.
Something like this (not sure if that was exactly it, I had it laying around), anything thinner would probably just bend.

All hacks..

Just buy the damn tool at a shop. It'll be cheaper than having the shop do it for you, and you sound like you have the skill to use it. I bought one about 40 years ago and still use it occasionally. My most recent bike though uses a different method although come to think of it, the tool may also work. It is supposed to be self-extracting, but I don't know where the self-extracting cap is. It may be in one of my many parts boxes.

...if you're not planning on reusing the crank, there are a lot of ways to do it.
