Remaking parts

14 posts in this topic

Right so before I start to explain what I want to do please note I'm am an absolute novice when it comes to this and if they made a dummies guide to do book I would be first to buy it. 

 

Right so let me explain what I would like some help with. I have a hrm resin engine set for Fujimis porsche 917s and I would like to try and replicate some of the bigger parts for personal use on the 3 other 917s I have in my stash. So basically my question is how should I go about it and what do I need to do it? 

 

Links to products would be useful. 

 

Thanks

Shaun,

Excellent idea! And goo on ya for having a go.

There's a topic on the WIP page by Capri-Schorsce about moulding a BMW M3 body. Not quite the scale you'll be working in but maybe worth a look?

Looks like plenty of help on the inter web...

how to mould resin model car parts

 

And a book...

The 917 looks great, I'm looking forward to seeing a grid full of your 917s!

Better yet, don't steal others' work by recasting bits. Buy more engines from HRM and support a fellow modeller and a small garage company. Alternatively, scratchbuild your own engines.

 

Now I'll wait for the firestorm...

Thanks injidup. 

 

And Rob at no point would I bash you for having an opinion as what you said is normally the way I would do things but as has been pointed out these engine sets are getting very very hard to find and when you want/need 4 sets it would be near on impossible to do as hrm don't make them anymore and when they did they were only made in small numbers compared to how many Fujimi 917s have been made. It took me 6-9 months just to find one guy that had on there website as available and then another few months for him to actually have it and send it. And then there is the cost factor as for the 1 set I have it cost me just over £60, now considering the actual Fujimi kits are only £17-22 from hiroboy.com I think my other half would kill me if I spent almost £250 on resin bits for £70 worth of kits. Like I said in my opening post as well is that this is all for personal use and I don't have any intention to try and remake others work for profit. Basically it would be easier to learn how remake just the bigger parts from the set than wait for the number of sets I need to become avaliable that is if they become available again.

If the parts are for personal use , no big deal.

I suggest something smaller to begin your casting adventure , the learning curve can be a little expensive and brutally unforgiving.

I went into it and spent some dough tryna get some good casts , best intentions and alla that. I did get it sorted and moved to metal casting as well , now I have a real good idea on how to make molds and the physical properties of mold silicone , resin casting material and metal casting materials.

There is a 'Metal Casting Work ' thread on this site , may be worth a look.

Good luck!

I'd love to have a go at this, I could have moulded the front end I scratch built for my 956, plus the rear frame I'm building for the Fujimi 917K.

 

Unfortunately I don't have the space at all.

 

Be interesting to watch how you get on.

I"m waiting to see how you tackle the vacuum chamber, but I won't hold my breath!;) :D Best of luck with your endeavors.

Mb I won't be using a vacuum chamber just careful mixing and gravity. 

 

But to update this i have some silicone rubber and polyurethane resin on the way so expect some test parts to me made soon.

I get the best results by having a sort of sprue run so that the resin is fed down first underneath the item and then rises up into the area of item being cast with a vent at the top to allow all the air out.  This always gives the most consistent results especially in terms of minimising trapped bubbles.

I'm not sure, I was think something with a simple shape like the rear wing plane of a porsche 956/962 as if it works nicely first time I always have a use for that kind of thing.
