Default Homemade thread chaser for head bolts?

So ive searched everywhere locally, and for some reason am m11/2.00 is the "unicorn of the bolt/thread world. I'm planning on making one from a old bolt, and if the arp head studs go in by finger easy, than I say mission accomplished. This will be an iron block, so no worries of messing up aluminum. I'll report back with my findings, Just curious of others success/failures?

Most of the DIY's around here just tell you to use the bolts you removed from the head, so it seems to be fairly common practice.

It works perfect. Trust me. I've done it.

Take a long bolt, and a short bolt. Cut 3 lines symmetrically in it with an an angle grinder or whatever you have; end to end.

It works just fine like that.

A standard bolt with cut reliefs works fine for cleaning but you really need to use a tap/tool steel to correct for distorted or cross threaded threads.

Absolutely agree with that. In this case though, it just sounds like we're trying to clean the GM **** out of the holes.

Yep, no damage that I'm aware of, of course I would love to have the correct tool, but that's also another week out and 50/60 bucks, I'll report back later today

Trust me!!!! The ARP thread cleaner is freakin awesome and worth the $40. I tried the bolt trick, but the ARP actually cleaned the heck out of the threads. I was able yo install my studs all the way down with my fingers.

I don't think trying to be frugal here is worth the possibility of dicking up the head bolt threads with a Bugard cut OEM bolt

I personally don't think it's worth the money. I too was able to run my studs down with my fingers, but then again it probably took me 4x longer with the bolt, since I had to make multiple runs, so o do see its usefulness.

I also hooked up a piece of aquarium air tubing to my shop nozzle on the air compressor and blew all the **** out of the holes. (Another trick that's good to know)

I'll gladly rent the two I'd need though if anyone offers.

Yeah, many folks have done it, my advice would be the proper chaser. I tried the bolt, and ended up with the chaser. Bought it, used it, and sold it. Not much out of pocket cost and very pleased with the end result

Great success! Bolts run down by finger, top end back together, took about 5 mins to grove bolt. I would not argue that the chaser is the "best way", but isn't this why we have the forums, it's to "hot rod" and share knowledge/tips/tricks? The 40 saved here will just go towards something else now, and I'll help my friends as well. thanks guys

I did this today and it worked great. Milled 3 grooves in the bolt with the Bridgeport. Simply cleaning out the trash left behind.

I blow them out with air first, like a bunch, then use a stock bolt with a few lines cut in it.
It's worked well every time so far, and it's free
