1/8 Aston Martin DBR1 scratch build

PURE GENIUSE ! Jim

You said in your first post:
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.

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...

A quick add-on...


Carbs assembled.


Fuel lines to fit and then they can go on the engine.


Linkages after that.

Just great work

[Guest]

Many thanks you guys.


The 'stand-alone' engine is nearing completion.


Just a few wires, linkages and the fluid reservoir to add.

A small update today.


I've now got some body parts back from my friend and will be getting started in the next few weeks in earnest.


I've still got a book to finish and my publisher is doing his nut - 6 months late already...
