Head stud threads

I have read on this forum that the threads in the block for the head studs are different than standard course threads and you should not clean them up with a standard tap, so how do you clean them up?

Re: Head stud threads

Get a stainless gun cleaning brush of the correct size, probably a 38 cal. And use it in your drill.

Get a whole set, and look over the selection of other sizes and adaptors! Gun brushes are extremely useful on old cars. You can easily get sizes made for guns from .177 to .50 (what ARE those guys shooting with .50??!?), and they will get out crud that othere tools have trouble dislodging.

Heck - I just love my Browning 0.5" HMG mounted on the back of my 'technical'.

If you have some bad buildup in the threads you can make your own thread chaser. Get a bolt from the hardware store. Preferably grade five or better. Use a Dremel with a thin cut-off disk and cut a groove lengthwise across the threads leaving a relatively sharp edge similar to a tap but the groove does not need to be that wide. I actually cut the groove at a slight angle so the sharper angle does the work as you screw the bolt in.

Shooting a .50 cal. Thompson Black Diamond inline muzzle loadrer. So having them on hand is manditory anyway. The current black powder and pyrodex makes keeping it clean a real pain at times. Rod

Desert Eagle .50 Cal- + Same smoke pole you have + the Thomson PA hunter flint lock- I use a Nylon Brush then Brass Brush on the Guns.

I have most caliber sizes avail- but would the prefered brush be the nylon or brass for the threads in the car?

Re: Head stud threads

there are also thread chaser kits available. I got a nice one from Sears. It is true that a tap or die are not good to chase threads.
