Just been looking at a solution for this in the KB10 but my extractors are very close to the front suspension, I think that with the innertube on it will get very close to them, i'm a little worried about the heat, dont really want a fire in the engine bay! any thoughts on the heat resistance of the rubber?

Thankyou for the tip clyons8. it sounds like an old trye inner would work well, it is already stretched.

I think I have more drive to make his part from wanting to know if I can do it now than from wanting the part.

Thank you for the comment on my build diary unfamilia, not much happens each week so it gets few updates. but I am glad you like it.
I wanted a good record of what I have done with as much usefull info for anyone else doing the same build.

well me and rubbers dont work- 2 kids... but i like what your trying here. great work, and a nice build site too.

Nige, your jake the peg.

I just used an old tyre inner on mine in PNG. Worked a treat and I got a couple of pieces out of the one bit of old inner tube. Might be worth asking a tyre shop for some old inners from a 4wd or the like? Might save you all this trouble.

Nice work guys, I can appreciate the time involved in the R & D, not to mention the costs!
And Mik, dont even think about me and the new artifitial centre leg at the same time :)

I found a company that manufactures rubber localy and gave them a call,
They had a minimum spend of $500 for uncured rubber.
The guy I spoke with said it needed industrial machinery and a complex manfacturing process to cure it properly. (Not me in my back yard).

I asked an engineering mate that gets rubber and polyurethane poured regularly about having rubber poured, But he said that I would be better off with a sheet as I have been doing. It's just finding the correct material...

I had a rethink on how to find a suitable material...
I was trying to find a rubber that can be formed like a plastic.
I should have been looking for a plastic that is soft like rubber.
I think I have found a material that will do the job, "santoprene".

It will be a little while before I can give this a try as I just spent waaaay too much on yahoo yesterday.
so I need to build up some savings again. As I may be moving house in the near future.

If that fails I was also thinking of making a mould and having it sprayed in rhino lining, I got a sample from them a few months ago, it looks and feels like a stiff rubber,i think it would work well.

I like that you have decided to have a go as well.
The material you are using looks like it forms very well.
How hot do you need the oven before you can form your material?

thats definitely the go!

"i got some soft orthotic material and put it over a brick and put in the oven" awesome looks to have worked a treat.

Got the better of me today, had too give it a try so i got some soft orthotic material and put it over a brick and put in the oven, as you can see it went to shape and you can squash it and it will bounce back to shape. It is about 1 and a half mm thick.

Mik, that new artifitial centre leg you want made, i can make it for you so that you wont feel inadequate anymore.

Thank you very much.
I will wait to see if I get a relpy from the rubber company that I emailed.
If I have no luck there I may send you a pm with my details.

I don't think they need to be rubber, I think they just stop water and dirt from being thrown off the front tyres into the engine bay.
If I can't get rubber to work I may just make a fibreglass one.
But I do like the idea of rubber.
It would look factory, which is what I am going for in my atempt to make these parts.

I am amazed at how many people on here are willing to help out.
A big Thank you to the datsun community.
