Last time I priced it Resin wasn't actually any cheaper than 3D print any more. It's labour intensive and you get a lot of rejects.

Hi Gang;

I'm very lucky in that I have a CJM 92...but am still following this with intense interest.
If it succeeds, I shall probably be in for one (or two!!)

Hi Alan and all,

Class 60 cab interior - very good idea and it might be but it seems a shame to take it out. Have to remove the light guides etc. Where as the body maybe reusable as a whole (swaping 2 bodies onto a single chassis to free up a chassis for the 92 project)

Thanks

Hi Russ

Since the 92 was largely based on the 60, and I believe the lights on each are to group standard, might it be possible to use the Farish 60 chassis with the cabs/light guides and arrange for your 92 to have working head/tail lights?

In terms of features that would put it ahead of the (admittedly lovely) CJM 92 which has no lights....

cheers

Ben A.

The only snag there is that the Cl.92 lights are underneath clear covers - not just flat clear covers either, they curve to match the bodyshell.

Hi Guys,

 Regarding lights, I made best efforts to ensure the original main circuit boad is kept (just lowered) so it would be simple to do lighting by whatever means anyone fancied (and DCC though thats going to be very tight). Some ideas being...
  Chop the existing lighting pcbs down (as its would otherwise stick up through the pantograph well) and rewire. Tricky as the wires are fine but that keeps all lighting as original. Then its making your own light guides - plenty of articles about that. I would probably do Poly light guide for the forward lighting only - the shell is thick enough on the front to easily support this but remember the shell is transparent.
  OR given sufficient interest, once the cab is done and we have V2.0 on a chassis maybe we can do light guides in 3d print - Will need to ask david but the material is transparent!

If you just need minimal forward lighting then an appropriate LED body mounted on and wire to the main pcb seems simple.

Light covers are definatly wrap round (should be more visable on the primered version) and I think this maybe possible with a coat of liquiglaze - works on most things to look like lenses etc

IF the class 60 shell from the donor chassis can be left 100% intact it can share a chassis with another shell and, what was two class 60's can then become a 60 with two body shell options and a class 92 - I think thats quite ecconomic.

Have a good day!

Regards
Russ

Can't be totally sure but the windows do look a bit wrong from that angle. Horns maybe a bit too close together too.

Other oddments - the windoscreen wipers are on slightly raised rectangles flush or slightly over the frames and the top of the flat block in the centre of the nose isn't flush at the top if I remember rightly but has  slight lip.

One of the best ways to get a clear view of the nose is probably to look at photos of Bart. The white paintwork makes the various edges and joins very clear.

This one shows the differing window heights pretty well

WOW :o This sure does look amazing!! I already have a CJM 92, but 1 of your bodyshells would not go a miss as I have a spare 60 ;)

This is great. All new models will need tweaking but that's a very good representation of the 92. As my next layout will feature catenary I would be interested in one of these to go on one of my 60 chassis, especially as one of my 60s has a cracked body-shell. I feel a red 92 coming on!

I'm pondering one to match the Nightstar coaches. Unthinkable at £500 quid but at a sensible price I'm willing to have a shot !

Hi Russ

That is looking very good - but I think Alan is right to draw your attention to the relative size/position of the cabside windows compared to the windscreens, and the spacing of the horn recesses.

Returning to the chat about lights, how about drawing in recesses from the rear to simlate the position of the bulbs on the prototype?  The outer lenses could be masked off when painted, then the recesses inside painted white/red then black - similar to painting racing car bodyshells from the inside.

The round recesses could be painted to look like bulbs, or could be the locators for any light channelling fibre optics or similar that the very keen could fit...

cheers

Ben A.

Hi Ben, Alan and all

Thanks for all the input, much appreciated and all noted - the whole front end is getting a rework to correct all thatís been pointed - fingers crossed for v2.0!

Lights - in the deep thought stage. At the very least, as it is, Fibres will work. But what Ben's has suggested maybe possible and would be really good - see what can be done.

V1.0 body progresses at the body shop to see what the finish might be like...
Its had a good few hours of wet and dry, fibre pen to get rid of what I call the digitalisation of the shell and its gone really well, feels smooth now. The plastic can handle quite a bit of stick (not that Iíve been giving it) which is good.

Regards
Russ
