1:64 scale HO Slot car resin bodies

[noir]

Anyone here ever cast a resin slot car using a Hot Wheels or Dub City body as the master? (I know with Johnny Lighting you can make the screw post when you cast the mold).

My question is, how can you attach the resin body to the Tyco, AFX, etc. chassis? I would imagine that the inside of the resin body will be completely smooth. How do you fix the body to the chassis so it doesn't come off everytime you crash? Yet make it easy to remove so you can perform repairs, etc.

Please advise.
 
Thanks,

Well, this really isn't BYOAC artwork.  I'm moving to everything else.
There are probably better forums out there than BYOAC for this subject.

Noir,

It depends on how you cast the body.  I always use two piece molds which allows me to cast the mounting points into the body.

Look at this page: http://erikruud.freeservers.com/maelstrom/resin.htm

You can see the mounting points in the second to last photo.  The Pronto Cruiser molds were made using a diecast for the master.  To get the mounting points, I had cut them from a broken bodie and glued them to the inside of diecast before I poured the silicone for the molds.  AFX mounts would be even easier because you could use bits of styrene to fabricate them.

nice work erik! hey the silicon you use, is that something especially for casting? im planning on casting some parts myself soon and could use some advice. i know the resin will be casting resin (polyester i guess?)

The silicone I use is from Smooth-On. 

Alumilite is also good, and even available in some hobby shops in the USA.

I'm not sure what you have available in the lannd of Oz.

The generic name for these siliconse is RTV Silicone.  RTV = Room Temparture Vulcanising.

The resins are usually polyurethane based.  You can get polyester and epoxy resins as well.
