On hold...

...or at least very slow progress at the moment. Finding it hard to find time now that I have to drive out to do anything on it. Things will pick up again when I'm in the new house and it's back in my garage (Sept)

Body printed

by Ivan Sentch 22. September 2013 19:47

The body's now fully printed and I've still got 12x 1kg reels left for the dash so that means the doors, boot, bonnet and body have taken 52x 1kg reels. No more assembly yet because I've been busy moving out of our house (which is done now & both cars relocated to their new home for the next year).

I'm preparing a post on how I slice up the parts which a few people have requested coming up soon

I've had a few people request this so I threw a facebook page together, look for Replica DB4

Bonnet printed...

...still assembling though, this time I'm trying to assemble the border first then work in. With the boot I did one layer rows and attached them from the top and bottom in, I was surprised when there was a gap in the middle, I was expecting with the 0.5mm rail  the printer prints that I would have to sand it a bit to fit snug.

I put this down to the inaccuracies created when the print peals off the bed (due to inconsistent cooling rates) when it rises off the bed it also distorts out or in so if you don't compensate for this when you attach it all together you end up with things like this.

I've got some weights on it now so I'll take an in-progress picture later, for now here's a picture of my 250 GTO kit I built 10 years or so ago, it's also got the RB25DET in it that I'm planning to use in this (but I would like to transplant the v12 from a 750 I have been sporadically working on into it one day, hard to work on something that's already working though)

First blog

This will be a scratch built replica of a 1961 series II Aston Martin DB4, fiberglass body, space frame chassis using a donor car's bits (engine, drive train, suspension, etc).

The fiberglass body I will make by first making a plug, taking a mold from that plug and casting the body from that mold.

The donor car will be (at this stage at least, I may change my mind closer to the time of needing it) a Nissan Skyline GTS25T which is pretty cheap (about $4000 NZD if you're looking hard enough), fast (250Hp at 7psi and intercooled standard, no internal changes required to run 12psi), it's wheel track will fit the body (which is important as it's not easy to certify suspension modifications in New Zealand), and I'm already using this engine in my 250 GTO replica I built a while ago so I've got spare parts when I change that to a BMW V12 (much much later)

Once I've got the above I'll build the space frame chassis (can't design this until I can measure the suspension), I'll be tacking this together myself and then handing it off to a professional welder to complete.

Then attach the body, paint, interior, etc.
