Old Burnt Out Cox .049 Glowhead Wanted

NEW222 wrote:Hi there. I am looking for a burnt-out, non-working glowhead for my Cox .049 engine. I am playing with making my own to use a standard glowplug. I have only one, of which was tapped with a standard tap. I now have aquired the correct tap, and would like to start experimenting. So if anyone has one or two kicking around, please let me know. I do know that the heads are available commercially, but I like to do things the hard way! Thank you.

I've got one you can have.

I don`t like to bear bad news.......but, the biggest problem with your plan is.....its more complex than you thought........you are trying to make a super-low compression head. The (standard style)glowplugs have a huge cavity(compared to cox glowheads) for the coil...ergo, lots of compression eating cavity.

Problem #2, the glow plugs seal at the top of the head with a coper crush gasket, allowing even more compression loss until she will barely pull her own weight if she will run at all basically.

There is some good news though, there are glowplugs available that work better than standard, like the turbo glow plugs (for 1 ), but they take a totally diferent tap, a larger diameter bore, and it has to be exactly tapered at the base of the glow plug.
There was a thread/conversation (several actually) over at rcu or rcg about it. If you are really curious look up my thread 9in a "search")on the G-mark.03 ( an extinct, little known japanese engine from the `80`s )glowheads over there.
I`m not sufficiently equipped to do the precision it takes and sent my glowhead out for the conversion

Well thank you for the heads up, and the problems that I will encounter along the way. Love a challenge. I will definately not abandon this plan yet, but look forward to meeting this head on, no pun intended.

That is a different head - the challenge is tapping and converting an OEM cox head.
