Matt Bacon AMPS Posted September 4, 2015 Report Share Posted September 4, 2015 (edited) Here are some CAD drawings of my forthcoming Sound Cart (hopefully available end this month). Last chance to send me your ideas and feature requests before a final design is locked down. Made of aluminium the cart is extremely light-weight yet very strong. It has been primarily designed as a bag cart however it would be suitable for those that need a compact "grown-up" cart (max load 25kg). It features a total of 18u storage (3x 6u) in addition to 3u dedicated to video monitor use (which can be angled). Because standard 19" racking is employed, you can customise it using any 19" gear (shelves, drawers etc.). There will be a range of optional extras for things such as boom poles etc. These are still being finalised as is the price of the cart. The cart can be easily and quickly taken apart for storage or transport. Dimensions: 1007mm (H with monitors folded down) or 1079 (H with monitors fully upright) or 907mm (H with monitors folded down and wheels off), 697mm (W), 508mm (D) Please PM for further information or with your comments/suggestions or visit my Facebook page: http://facebook.com/soundcart Cheers Matt Edited September 4, 2015 by mattbacon Quote Link to comment Share on other sites More sharing options...
Matt Bacon AMPS Posted September 4, 2015 Author Report Share Posted September 4, 2015 Here are some further CAD drawings for those that wanted to see the cart with shelves and drawers. Obviously this is just an example setup. Because standard 19" racking is used you can add any 19" rack equipment in any configuration you desire!

Michael Miramontes Posted September 5, 2015 Report Share Posted September 5, 2015 Looks just like the EuroCart. Quote Link to comment Share on other sites More sharing options...
Matt Bacon AMPS Posted September 5, 2015 Author Report Share Posted September 5, 2015 (edited) My cart is the result of looking at existing cart designs (including many from this website as well as the EuroCart) so comparisons are inevitable I suppose. I'm accepting your comment as a compliment ;) One advantage I say this cart had over the EuroCart is standard 19" kit can be used (which ironically could be argued as a disadvantage as it makes the cart wider!)

Bash Posted September 5, 2015 Report Share Posted September 5, 2015 Hi Matt, Do you remember the Ravencourt cart? It looked broadly similar to your CAD drawings above. One of its great failings was that it had the axle points for the big wheels in exactly the same place as you are proposing.The consequence of this was that the whole cart can pivot 'away' from the recordist (assuming recordist is in the mixing' position), ie the top can pivot away from the recordist, and it basically falls over really easily. The way to stop this might be to move the axle/pivot point away from the recordist by about 50mm. So - where your arrangement, looking at it from the side, might be seen as an upside down 'L' shape, it would become an upside down, lopsided 'T' shape - with the much longer cross piece heading as per your current L thing, and the shorter part of the T crosspiece going away from the recordist. This would make a HUGE difference to the cart's C of G around the pivot point. It doesnt make your engineering job any easier, but it will make the cart a whole load more stable. Other than that it looks like a great idea. Keep up the good work ;-) Kindest regards, sb I I I I I 0 _______ vs I I I I I 0________ Quote Link to comment Share on other sites More sharing options...
Matt Bacon AMPS Posted September 6, 2015 Author Report Share Posted September 6, 2015 (edited) Will there be any proprietary components? While I have attempted to not use any propriety parts it some became obvious it was unavoidable. The anodised wheel forks are bespoke.

Remember the Trakker cart well (and it tipping over!). I had looked at the axle position during the design process and took the descision to reduce the footprint of the cart instead (as many had requested a compact cart as possible). Malcolm Davies made a similar point to your own on another forum. I must see how he positions his axle. The beta testers made no reference to this issue so I had assumed all was well (or they loaded the cart sensibly). I should perhaps take a look at it once again. How did you tackle this issue on your Zucca cart? Quote Link to comment Share on other sites More sharing options...
Bash Posted September 6, 2015 Report Share Posted September 6, 2015 I have always been worried about the Zuca cart, though in fact the weight was all slightly forward of the CoG/pivot point over the axle, as the Zuca handle had to go between the back of the Zuca bag, and the rear of the shelves. That said - the Zuca cart was always intended as a very lightweight cart, for job requiring greatest portability, but still in a cart form. Currently I am looking at making a kind of drama strength bag kit, for a trip abroad. It is, in fact, tomorrows job!!!! I have a vision of a kind of X shaped trestle thing, like the suitcase stand thing that you sometimes get in hotels. I can then heave the bag to wherever we are going, open the trestle thingy, and plonk the bag on it!! Have a good think about that axle placement thing - I would have thought that 50mm could make a huge dofference. If you fashioned some kind of shelf in the 50mm between the wheels you'd have a great shelf for the bottom of boom poles to sit on ;-) Kindest regards, Simon B Quote Link to comment Share on other sites More sharing options...
Matt Bacon AMPS Posted September 7, 2015 Author Report Share Posted September 7, 2015 Anyone have any experience if the EuroCart tipping over unexpectedly due to its axle position?? Quote Link to comment Share on other sites More sharing options...
Malcolm Davies Amps CAS Posted September 7, 2015 Report Share Posted September 7, 2015 Matt, Our Bag cart is based on a Magliner sack cart so as standard the wheels are aft of the upright frame so therefore there is no chance of it tipping over.

Matt Bacon AMPS Posted September 7, 2015 Author Report Share Posted September 7, 2015 Which Magliner model do you base it on Malcolm as I can't see it advertised anywhere online? Quote Link to comment Share on other sites More sharing options...
Matt Bacon AMPS Posted February 21, 2016 Author Report Share Posted February 21, 2016 The Compact Bag Cart is now complete. Orders will be accepted next month. Thank you to everyone for their constructive comments and ideas. Quote Link to comment Share on other sites More sharing options...
Robert Bluemke Posted February 21, 2016 Report Share Posted February 21, 2016 Hey Matt, Does the bag cart fold up at all? I really like how compact the case cart becomes when folded. Great work, look forward to seeing what else you come up with. Quote Link to comment Share on other sites More sharing options...
