I have been fiddling with some resin lately, trying to learn a few tricks. These are a recent small run. The failure rate is still fairly high but I am pleased so far.

Hi John.
The parts look pretty good to me, nice clean castings, not too many pinholes from trapped air.
Some of years back I had a bash at both casting of resin parts, and also urethane tyres and had a varying degree of success. I'll be having another go at both in the not too distant future.
I did driver figures, all based on the Airfix Bugatti driver, keeping one driver standard, giving one a pudding basin helmet, with two others having peaked corker type helmet and a jet helmet, these latter two with gloves rather than gauntlets. Most came out well, with the most common casualties being noses and fingers. The figure was actually fine for Nuvolari, but a little small for Mike Hawthorn.
The mould lasted about two years. The end was not due to tearing, but I used a soft silicon for the working part of the mould backed up by a harder silicon. After two years and perhaps 20 batches of 4 figures, the mould had become so deformed that it was fit only for the bin.
I also had problems with the tyres, since at the time I still used the old Airfix track (styrene) and made the tyres for the Bugattis I was making at the time. After perhaps two days the rubber unfortunately reacted with the styrene, ruining both the track the car stood on and the (styrene) wheels on the car. I was told that I should have left the tyres for a week or so after moulding, but had already left them for a month and repeated the test a year later, with the same results.
I'm keen to have another bash since I will need softer tyres for the Delage rears and need many resin parts including more drivers.
Peter.

Thanks for your reply Peter. I am keen to do tires too but there are other pressing priorities such as home and family and a track to be built at some point in the not too distant future.
I do find time and reasons to be at the bench as often as I can though.

Hi John, I see you've got a '70's type helmet in there? That should come in handy for those of us in that era as they are pretty hard to come by. Currently only Maxi has them and they are soon going to be finishing I believe. Will the parts be commercially available? Andi

Hi Andy, Here's a link to the Proto Slot page with the accessories. www.proto-slot-kit.com/psktech.htmlMy French is well.. non existent, but it appears that the drivers package is temporarily out of stock. You might want to contact Chris directly.

Thanks Andrew, the seventies helmet head was chosen because there is a face rather than the usual blank surface. If someone wanted a few then there would not be a problem in producing them for that individual. Regards John

Well, in fact I am looking for 70's and 80's helmets with the visor down (closed). No driver used an integral / full face helmet without the visor or with the visor open. And as I use my slot cars in a track ...
Any chance to make an integral helmet with a close visor ?
André Acker.

Andre..maybe you could add a visor yourself? This head is larger than some others I have seen. I will continue seeking suitable examples to copy. Regards

Thanks for the suggestion Andre and link Mark to PSK site. Apart from being out of stock I can't really pay 19.90 euro for one '70's helmet!
