1:29 detail parts

Modeling
#1
As a scratch-builder, one thing I have always felt was lacking in the 1:29 market were AB components. In the past, when I did resin kits, I always found myself cobbling something together just to get me through the next kit. I guess there were passable, from 3 feet away, but I always felt like they were a weak point for me. In the past few months, I’ve got my feet wet in 3d modeling & printing. Now I finally feel like I can offer something I’m happy with.
 
 
See: http://www.shapeways.com/shops/burlrice
 
 
These are designed with the hobby caster in mind, so you can make an RTV mold and cast your own (if you’re so inclined), or you can use them as they come from the printer.
 
 
Right now, I’m only offering the whole set for sale. There are other models you can look at, but they are not for individual sale. The reason being: shapeways has a $5 minimum base charge, plus actual volume of the print. So its considerably cheaper to do the set.
 
 
I hope some of you find this of use,

Burl,

That is great! I hope you find a market for your products. Are you going to the East Coast Large Scale Train Show?

If not contact me, private email or message.

Nice, Burl…

Burl,

I saw that you sent me a message, don’t know if I succeeded to send one back.

Please email me at

Yes Rooster, this is code - you won’t be able to figure it out.

Burl,
Welcome, glad you made it over here. Great stuff.

I will figure it out even if it’s the death of me Ric and I do have a secret decoder ring.

Hello Burl, are you into making any more car kits???

Hi Burl, I was just re-reading your GR articles on casting (Aug 07-Feb 08) recently, hoping to dive in to resin casting. And I just ordered 6 window and door models today from Shapeways, to serve as masters. So thanks for those articles!

I’m plowing through all the decisions on vacuum pumps and chambers now… I think I’m going with a Robinair 2-stage 3 cfm, pulls over 29"Hg (they say). Ever messed with the Harbor Freight equivalent? For $20 cheaper, I don’t think I want to risk it…

Anyway, I was pleased to see your recent post, and have a chance to say howdy and gracias.

And really nice modeling, what software are you using?

Looks good Burl, Now I think the time has come to mass produce those Hicubes… :slight_smile:

I’ve been using the HF pump for more than 2 years now and it works great. I also use their paint pot but wish I had bought one from Sears. The clamps are better on the Craftsman.

Cliff: I am using Sketchup.

You didn’t say what your having your patterns printed in, but if they are nylon, you better seal them with something to make them non-porous. Otherwise, you will never get the RTV off them.

Burl,

What are you using to seal the patterns?

#15

I have not tried to make a mold from anything nylon. I did have some parts printed in “frosted detail”, which has more grain that “frosted ultra detail”. The RTV did not want to let go. Shapeways tells you the nylon is so porous that it will soak up paint, so I can only imagine RTV will really bite into it too.

I was considering using Future floor polish on my FUD patterns, but haven’t tried anything yet.

Got around to casting some in resin:

Any noticeable shrinkage from the 3D printed part to the resin copy? I know if the past you’ve mentioned that 1st and 2nd generation molds will have a slight shrinkage percentage that must be taken into account. Didn’t you say 2%?

Stuff this small, I generally don’t worry about it.

I have added some 1:29 air hose assemblies to my shop:

Very cool. 3D printing is going to lower the pain of making highly detailed models in large scale, when items like these are readily available, like so many detail parts are in HO
