Thanks (Tony) ukwookie that will be helpful.

I'll look for a few more higher rez images on the web for a comparison.

Yep, Tony is right Colin; mainly Airfix models were used by our U.K. model maker friends

Here's a small update on the flamethrower.

I had chance to turn the rest of the pipe detail on the right hand side.



I'm reasonably happy with it. Just needs a bit of tweaking and then moulding and casting as one piece.

I hope to get back on with the build more seriously soon and I will post updates.

Hopefully it should start coming together as a finished piece over the next few months!

The piping sure looks sharp Colin...eager to see the next update

[8th_Passenger]

Joberg, the shapness is the thing I'm thinking of changeing. I may go in a bit deeper with the grooves and then round off the edges.

Do you think that could keep what you have already and simply put a small bevel on the edges. It could "open" your grooves

[8th_Passenger]

yes joberg my plan is to keep it pretty much as it stands now. I was only planing on making the grooves fractionally bigger. Maybe I'll try a needle file first.

Ah, o.k. got it

[LadyVengeance]

This looks amazing!

[8th_Passenger]

Thank you LadyVengeance.

I did the adjustments on the turned pipe. I took joberg's suggestion and mostly used a needle file to open up the slots. Worked a treat.



Using my trusty Lego I made a one piece mould.



I cut the mould on the underside, so the seam will not be visible when it gets attached to the body.

I then bent up some 1/8th inch steel rod, to suspend in the mould, to give the piece a bit of extra strength.



The casting came out nice and clean.



This week I started working on the dummy white tank. Because I need a hole all the way through I decided to make the pattern in sections so I could drill a hole through each section comfortably.





The top section still needs its hole drilling.

Here's a comparison to my real tank.



I plan on doing a two part glass fibre mould. A piece of hexagonal steel will run through the center of the tank to take the fittings at either end. The final cast will be glass fibre.

Glad I was of help Colin Love the pipe! As for your tank, doing it like this will surely reduce the weight of that baby

[8th_Passenger]

Spent some time last week sorting out some smaller jobs on the flamethrower.

I decided to remake the small detail piece which hooks over one of the Hornby Piers on the right side. The perspex one I had 'pinged' off due to insufficient gluing surface.

I made it again but this time put a web across the base. Rather than gluing on the new perspex one, I moulded it and stuck a fast cast one on. It's still fragile but feels better!

You can see the fast cast one in the second picture.



I filled the semi circular cut out on the right side and blended it into my routed edge. Also I drilled the exit hole for the propane pilot flame feed.
Then using some EMA I sketched in the pipe which runs on the forward lower right side.



A wider shot.



Here's an internal shot showing the polyurethane pipe connecting to the propane bottle. I shortened the turned brass connector I made and notched out the back of the trigger housing for a better fit.



I've drawn up some plans for the 'Nostromo Antenna' detail mounted on the left side. I'm making it in sections, these will slide onto a steel rod.





I've done some similar drawings for the pipe on the lower right side too. So these should start coming toghether in the next few weeks.

I got my hexagonal steel bar today to mount in the dummy tank. So I hope to get that cut to size, drilled and tapped this week. Then I will finally be able to hang two tanks off the unit.

The hex bar is quite heavy so I dont think it will be too light. I can always ad some ballast into the glass fibre tank.

Great update Colin...eager to see that baby in all its beauty

[SKIN JOB 66]

BRILLANT WORK as always, Colin !!!

Just a quick update.

I drilled and tapped the hex steel to run thru the dummy tank.

Here are a couple of pictures with the fittings screwed on and the tanks in place.





I still have a bit of alteration to do to the hex bar before I blend the tank together and mould it.
