Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: topalle on April 21, 2014, 06:04:09 PM wow... nice... This material is foam board / sunboard right?
Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: pratap on April 21, 2014, 06:25:23 PM no it's not :)
it is some sort of light weight plastic i don't know what it is called but i'm sure its not foam board the strength of this thing is great Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: topalle on April 21, 2014, 06:27:57 PM Is it laminated with paper?

Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: topalle on April 21, 2014, 06:34:06 PM I have no clue what this material is... What did you ask for and in which type of shop?
Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: pratap on April 21, 2014, 06:38:57 PM no its only the sheet
it is like acrylic (plexi glass) but with tiny air holes in it and it also handles fire very well cause when i tried to heat it and bend it, it takes so long @topalle Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: topalle on April 21, 2014, 06:40:30 PM Oh! Its a great job there.It seens no one has used that material till now. Looks like you did a lot of sanding...

the curved shapes are obtained by lot of heating and bending Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: pratap on April 21, 2014, 06:58:50 PM more pics

Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: Gajjark on April 21, 2014, 11:48:54 PM hai great work. All the best.
Friends it foamboard only. Title: Re: Scratchbuilt Speed Boat #sweepstakes 2014 Post by: pratap on April 22, 2014, 12:01:10 AM @gajjark no sir its not foamboard i'm sure f that
i don't think a foamboard sheet sustain direct flame for 5 minutes without melting, i did it for bending the sheet |
