Looking to correct the sear angle on a new build. I admit I haven't really shopped around or know much about the subject. All I know if my sear and hammer have the wrong contact angle. What are some cheap usable jigs and stones to do the job my self?
Thanks.

No clues as I haven't done one. Yet one of this guys videos should answer you question. https://www.youtube.com/channel/UCzhEsYvl_CcT6toiX4R7RYA

I have used the Ed Brown jig, which is available from Brownells.  I've used Brownells stones with the jig.  The Jig is not too expensive, the stones are a bit pricey.  But, the quality of the stones is outstanding and probably necessary for getting a satisfactory job.  In particular, the surfaces of the stone are square and perpendicular to each other -- a requirement for squaring the hammer hooks prior to doing the sear.

I would recommend this set-up to you and would buy it again myself if necessary.

Thanks. Ordered it last night.
