[NSRCA-discussion] Help - Glow Plug Thread Size

[Dennis Bodary]

Tower Hobbies sells a Tap 1/4x32 from higley. part # LXL774 6.69 and also a die LXL776 15.59
Depending on how bad your cylinder head is it may need to be helicoiled. But maybe the tap will save it.

1/4-32 is not a common size. Clarence Lee advertises in RC Report and other magazines (less than $15) to install helicoil threads. Just send him the head & the check and it will come back fast.

Does anyone know the thread size of OS glow plugs (Type F, 8 or A5). Looks like I stripped out the head of my engine (OS160) and I'd like to re-tap it.
 
Thanks,
