Thanks for the suggestions for possible locations. Hopefully a suitable location will crop up when I'm ready.
Just a small update this week.
I managed to get the emitter end on the milling machine this week.
I bolted it to a rotary table and lined it up. Always stressful!
The machining went well.
I added the cross slots.
Due to rushing I missed the bottom off one of the slots.
Seen more clearly here on the underside.
So I used a milling bit in the lathe to add a recess.
This cleaned it up!
Strangely what I have made looks like a large tapping die!
Next week I hope to shape the front.
More soon.

Glad that the project is still on the burner. I'm sure you're eager to see it finished and working Colin |

joberg, Yes I would really like to see this project finished.
I think I am coming to the end of posting!
Maybe a couple more posts before the unit is finished.
However this may still take a few months.
This week I turned the front face of the emitter.
I'll need to add some fixings to stop the end falling off. But this gives you an idea of how its shaping up.
I decided I wasn't happy with my triggers. They weren't really strong enough in Perspex. So here's the start of a new design in aluminum. It will be simpler than the prespex ones (honest).
Whilst looking for the 'entry point' (into the main body) of the feed from the bottom of the white tank I noticed various shots of the fully detailed side. So not just used for the table shot after all!
The entry point for the white tank feed seems to to connect with the yoke on the red tank! I'll try and illustrate it on the next post.
So I've got to the point now when I need to start assembling and painting.
The only main outstanding stuff now is the 3 1/4" aluminum tube at the rear and the moulding of the white tank in GRP.
There are still lots of little jobs as I fit all the parts together.
Hopefully the next prgress post will signal the end of the build.

Ah! You know, like me, that little details amount to lots of work
But, yes, it'll be good to see that prop working! Keep up the great work Colin...end of tunnel is near. |

Thanks for your comments Joberg, Pro Mod and cratercritter.
I'm slowly working through all those little jobs.

Now the weather has got warmer I have been able to tackle my fiber glass tank.
I dusted off my laser cut former.
And coated it with some packing tape before apply some release wax.
Its been a while since I have done any fiber glassing. But it went okay.
I test fitted the steel core in the mould.
I added some grooves into my steel core to grip to the glass and resin in the positive cast.
It came out okay. I used aluminum powder in the gel coat to help with the painting and weathering.
I drilled a hole in the side so I could pour resin in to strengthen the inside. So I need to do a bit more clean up before I can apply the final detail to the exterior.
This is my simplified trigger concept. Using one hinge and one spring
I drilled a stepped hole in each trigger. One hole to tap (for the bolt) and a larger hole to hold the spring.
Like so.
I decided to secure the emitter end on with four M2 counter sunk bolts. They need counter sinking.
With the emitter end held secure I trimmed it flush with the main piece. I will replace the posi drive headed bolts with counter sunk allen head ones.
So here's an illustration of where I think the feed from the bottom of the white tank goes. I could be wrong. Its hard to see. It could just go straight up in to the body, which is where I've always thought it went.
Getting real close now.

Thank you retrogarde and Fred for your comments.
Only a few things left to do now before painting.

Thanks joberg and Isnochys79 for the comments.
I've started painting the flamethrower and have almost tied up all the loose ends.
So depending on how much free time I have I might have it finished by the end of the month.

cratecritter and Space Jockey thank you for your comments.
This is what I hope will be the 'final' build update.
Anything I've missed I'll put in the last post!
Here's the re-made trigger mechanism. I'm not sure if it's better than my original version but it works and is all metal. Which is what I was after.
I turned a brass connector for the pipe that goes into the top vent to give it some strength. The top bend I had to recast in white metal as the fast cast one (pictured) broke when I laid it down on that side.
I thought I would see what a modern spark plug cap would look like. The design of these hasn't changed much but I couldn't find one similar to the reference. So this was a bit of an experiment to see what it looked like.
It looked okay but wasn't really cannon!
So from the reference I drew up this.
Realized here in two pieces of turned fastcast. I need to do a fiberglass mould and then cast it in a cold cure hard black rubber.
Here's a preview of how the painting is taking shape.
Left side with a coat of primer
I've sprayed the body with grey primer, a mustard colored primer, aluminum and finally white. The idea being I can sand back the paint layers and get different colors showing through. I will then add washes to dirty the white down.
This is the start of the paint job on the top vent.
I'm not trying to re create the paint job accurately from any particular photo reference. I'm just trying to recreate the feel of the paint job and put my own spin on it!
I'll just keep layering until I get the look I'm happy with.

Colin thanks for sharing this great build with us. Your craftsmanship is only matched by your never ending pursuit for accuracy!
As someone in the industry I'm always interested in methods employed by others and I've learned a lot from your posts.
Looking forward to seeing this finished and hoping you have something just as interesting to follow up with - perhaps something with a bit of complexity to it this time and not this easy stuff! |

That paint job is going to be the bomb! I hear you when you want to have different washes. Lot's of "wear and tear" with that prop.
Keep up the wonderful job |

Thanks Pro Mod for the comments.
This project has been a challenge and taken far longer than I thought. I've learnt things too.
Just when I think I'm on the home stretch problems with the final assembly keep on cropping up. And then I realise why things have been done a certain way on the original.
But I'm getting there.
I hope I can do the paint job justice Joberg.
I don't think I'll be starting a new project soon. I need a break.
