Question for those in the know . Is the hammer face drilled for the insert ? How deep ? Are they bonded in place ?
or Is a hat made to go over the hammer face ?

Tuning Peek Insert for hammer face
- Thread starter SteveKralsAround

Ive made a few steel strikers with a peek insert. For mine its a threaded insert that sits flush with the face. Access to it was just a slot from the back for a screw driver. Its been flawless for thousands of shots now.

Pending the hammers HARDNESS ?
Many are VERY hard and require carbide drill or end mill to spot face a cavity. generally only need @ 1/8" depth. Size the peek a tad larger for a interference fit and FIRMLY press in then trim it flush. Diameter generally 3/16 to 1/4" * Only need it a tad larger than poppet stem diameter.
* If drilling ANGLE the peek stub to match drill point angle before pressing in.

Thank you to all !
I have a 5mm rod coming in the mail . I'll aneal the hammer face and use a carbide end mill .

Yep press fit works great too! Only reason I threaded mine was testing different stroke lengths and was quicker. Its certainly overkill.

I used a 1/4 " end mill x 3/16 deep on the hammer face on my Flashpup and machined the peek for a light press fit. and faced it off flush. Was suprised how soft the hammer is.
