soundtrane Posted January 6, 2008 Report Share Posted January 6, 2008 After my recent bad experience with fabricators, I decided to catch the bull by it's horns.

soundtrane Posted January 14, 2008 Author Report Share Posted January 14, 2008 Here is the next stage - SHELF OUTLAY and tube lengths. The shelves are going to be in old Teak wood, handmade and varnished. All shelves - 1/2 inch thickness. Boom pole holders to be in wood as well. I am aiming for the cart to be completely ready by 19/20th. best -vin Quote Link to comment Share on other sites More sharing options...

Paul Graff Posted January 14, 2008 Report Share Posted January 14, 2008 That will be a beautiful cart, Vin. In the drawing the wheels look small, but I see in the specs they are a pretty good size. Speedrail with teak shelves...Wow!! According to your specs the weight is going to be 62kg (1kg=2.2lbs) or 136.4 pounds. A bit heavy don't you think? Eric I see reference only to the weight-bearing capacity of the shelves; nothing about the actual weight except for the weight of the Speedrail, but 183g/ft is light.

soundtrane Posted January 14, 2008 Author Report Share Posted January 14, 2008 Hi Paul That will be a beautiful cart, Vin. In the drawing the wheels look small, but I see in the specs they are a pretty good size. Speedrail with teak shelves...Wow!! I see reference only to the weight-bearing capacity of the shelves; nothing about the actual weight except for the weight of the Speedrail, but 183g/ft is light. Paul Yes, I think it should be great, main purpose is to keep it light and easy to erect/dismantle and also to make it look good! Yes, the wheels were not drawn to scale - that drawing was more to display the tube frame and build of the cart. So I did not bother to draw the wheels absolutely right. I am working on the actual weight of the cart, typical teak wood density, weight of tube and couplings, et al. Since I am already on my way to get it all ready (I have a feature shoot coming up very soon!), I may be able to post actual unladen weight specs here very soon. Thanks for the heads up, I was wondering how come there was no response to my post for a long time! best -vin Quote Link to comment Share on other sites More sharing options...
t.elder Posted January 14, 2008 Report Share Posted January 14, 2008 One thing I noticed was that you've designed it to be 18" wide - wouldn't it be better to make it 19" wide, so you can install rack rails and rack-mounted equipment if you need to down the line? It was great to see your drawings as they've given me some inspiration for the cart I'm designing. Tim Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 15, 2008 Author Report Share Posted January 15, 2008 Dear Tim, Many thanks.... Yes, I thought about 19" but I really don't see myself using any rackmounted gear. Also, to make it 19" rack compatible, the overall width has to be 22" or so, which then beats the purpose. The maximum width of gear to be on this cart is the width of the Cantar, 12". best -vin Quote Link to comment Share on other sites More sharing options...

Paul Graff Posted January 21, 2008 Report Share Posted January 21, 2008 Thanks for the update, Vin. This will be a one-of-a-kind and very classy sound cart. It really is enjoyable to watch the progression from idea to realization. I'll post an update on my own cart project soon. Thanks, Paul Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 21, 2008 Author Report Share Posted January 21, 2008 Hi Paul Many thanks for the inspiring words! Here's the next stage. I have to finish this cart by tomorrow evening. My shoot starts two days from today! best -vin Quote Link to comment Share on other sites More sharing options...
old school Posted January 21, 2008 Report Share Posted January 21, 2008 Looking good Vin. Speed rail with the wood looks rich. Glad you went with the big rear wheels, they are a must in my book. Can't wait to see it with all the gear on it. CrewC Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 22, 2008 Author Report Share Posted January 22, 2008 Dear Crew, Thanks! I hoep it works out well in the field, I have a good feeling that it will... Almost all done but for some small things... best regards -vin Quote Link to comment Share on other sites More sharing options...
Richard Lightstone, CAS Posted January 22, 2008 Report Share Posted January 22, 2008 Vin, I am curious if that's the new wireless zippo lighter on the back corner of your top shelf (last picture Great cart. How do you have your teak shelves fastened to the frame? Regards, Richard Lightstone Quote Link to comment Share on other sites More sharing options...
Sergio Sanmiguel Posted January 22, 2008 Report Share Posted January 22, 2008 Vin, I am curious if that's the new wireless zippo lighter on the back corner of your top shelf (last picture Not only wireless but built in windjammer also included...

old school Posted January 22, 2008 Report Share Posted January 22, 2008 Hey Vin, looks great with all your gear on it. I wish I had a picture of the so called cart RVD and I used back when we were young, you would cry laughing so hard. Yours looks like it belongs on a pro shoot, and I am sure it will serve you well.

Guest Eric Lamontagne Posted January 23, 2008 Report Share Posted January 23, 2008 I envy those of you with cantar rigs, such clean lines without the clutter. Overall simple and light looking. Congrats on the sexy design! Lets hope you make lots of money with it! Eric Lamontagne Quote Link to comment Share on other sites More sharing options...
FSBELLA Posted January 23, 2008 Report Share Posted January 23, 2008 Vin, looks good, that "rich" wood is nice. how are you going to strap the cantar to the top shelf? sorry if I missed something? will you have a "antenna mass" of some kind for the lectro six pack?

Jim Rillie Posted January 23, 2008 Report Share Posted January 23, 2008 The Cantar has a 3/8 threaded "nut" built in the bottom of the recorder for that purpose. Jim Rillie Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 Hi Everyone, 99% finalized. Ready to go for the shoot tomorrow - 6 PM - 6 AM shift... Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 Sorry, I forgot to add a description. pic 1. obvious - the boom pole holders pic 2. one speedrail for the antenna mast (i'll post a picture from the field with the mast erected) pic 3. the LCD monitor fitted onto the small boom pole as of now. I am waiting to get a magic arm. I will try to weigh the cart and post results tomorrow. best regards -vin Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 Saw your flicker photos...looks good. Are you running v2.09b yet? Hi Scott, Thanks! Yes, I am running 09b... Will go on the field with it tomorrow night. best -vin Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 What did the cantar setup replace for your sound setup? It replaced rental gear with many problems. Before this I had a pair of headphones. I turn out to be the first sound guy in India to stick my neck so far out! I am confident I will make it through... -vin Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 looks good, that "rich" wood is nice. how are you going to strap the cantar to the top shelf? that "rich wood" is proably 40 plus years old! strapping the Cantar - two options - one as specified with the 3/8" socket, and two - with the KT bag skeleton, then there are many options. best -vin Quote Link to comment Share on other sites More sharing options...
soundtrane Posted January 23, 2008 Author Report Share Posted January 23, 2008 Dear Crew, I wish I was born earlier. There's too much purity in our craft and other crafts as well, not to mention film making. I yearn for that level of integrity. Many thanks for your appreciation of what I am trying to do - it is just a small way to prove that there is that level of professionalism in production sound available here in India - without the appreciation of it in any which way as of now. But I am a perfectionist and an optimist! I will keep working and taking it ahead, inch by inch.... warm regards -vin Hey Vin, looks great with all your gear on it. I wish I had a picture of the so called cart RVD and I used back when we were young, you would cry laughing so hard. Yours looks like it belongs on a pro shoot, and I am sure it will serve you well.
