I'm making two engines, because once the car is complete and in a case, the engine will probably hardly ever be seen.


This way, I'll have a 'stand alone' engine next to the car.

Another master class in scratch built cars on the cards .


I am following this one.

That's the good thing about scratch builds. Honestly I take my hat of to you. Awsome work so far.

Thanks you guys.


I've now added an exhaust manifold to the stand alone engine.


It's obviously short, as it goes nowhere.


I'm not adding one to the 'car' engine yet as that one will need to be made to fit with the engine in situ.


I make my exhausts using microphone cable over a thick wire core, and a hobby stained glass window pen for the welds.


The exhaust still needs painting matt grey/black.


All good fun.


Some wiring and decals also now added.


Roy.

You are without doubt one of the best modelers I've come across, and I've trawled a lot of forums, I just wish I was a tenth as good, I've said it before and I will say it again you could teach the manufacturers a thing or two.

You said in your first post:

So far, the main body buck has been made and is currently at a vac formers to get some shell parts done. Hopefully I'll have some body parts back next week.

How does the vac. form process work? (I know it is a suction process but don't know more than that!) The buck is a rather skeletal guide for making smooth parts. No doubt you have to tell them where the edges of the individual parts will go so that the closures will be tight, or do you get a single part which you have to cut up?

The card buck was filled with expanding foam - as used by builders to fill gaps.


It was then smoothed with a mini-surform, craft knife, files and sandpaper.


A vac form was taken and that was used as a mould to make a fibreglass model which was further smoothed, filled, detailed etc.


THAT one is the master for the vac form shell - still awaiting completion as my vac former friend had a major contract recently land in his lap, so my car bits are on the back burner for a little while.


No worries - LOTS still to do.

I woulde be most interested if you would post pics of the various stages. For example, after smoothing of the foam, the vac form, and the firbreglass model (before and after filling). Not that I would ever attempt such work but it would be interesting to see it done.
 
Thread owner
All the body bits etc are at the vac formers just now.


I can't take any credit for the vac forming as my friend does all that - it's his business.


I did ask him to take pics as he went along, but he's 75 miles away from me so I can't pop over and take them myself.


As soon as I have anything I'll post it.


In the meantime:


I've satin black/grey coated the exhaust and built a small piece of bulkhead on the stand alone engine.


This will hold the two coils and brake reservoir.


I've also re-made my Webers as the first ones were awful - the moulds had been used far too often.


On we go...


Roy.
