Ok then Gents, I've had a very successful day playing with CAD (probably about 4hrs worth). Thanks to Chally 2 with those pictures of the 35mm Snatch Block that CRARRV uses. Way better info than what I was working with before.

Anyways, see the pictures below, I'll get this made up maybe by RP, depending on cost, I may wait until I'm back to Aberdeen next year and make them myself on my CNC Mill, we'll wait and see what sort of detail comes back on the Bowman aerial.

Comments (positive and negative) most welcome....

Cheers
Andy

Gents,

Attached is a few photos of the CRARRV crane boom I built, I can't or don't want to finish it as I'm a bit worried that the dimensions may be out since I don't have the actual model hull to hand I can't do any gross error checks......

Anyway, comments welcome.

Cheers
Andy

Gents,

I got the Bowman Aerial Rapid prototype made, looks good eh?

The pictures don't really do it much justice mainly because it's not been undercoated and the light is bouncing back, but you should get the idea anyways!

Hello all,

Just a quick message really, the inventor bug has bitten again, in fact when I look back at all my modeling phases they almost always start around November time and run into the end of spring, then I get back into my golf and modelling takes a step back.

However I digress, i don't have any pictures to show you just now, but I have a couple of designs that are being fabricated as we speak / type.

1/6th Scale Fire Extinguisher;
1/6th Scale 24te Pear Link (required for the CrARRV recovery chains);
1/6th Scale 19te Connecting links (probably have to get that one re-done though);

I managed to get my Tow Wire End adapters designed, looking to get them fabricated over the new few weeks.

I managed to find a rapid prototyping company who will batch produce my designs, meaning they will fit in my small orders with existing orders, which means instead of paying £150 for a part, I'll pay around £50 instead...........

Does anybody have any details on the fire extinguishers for making up decals?

Cheers
Andy

Hi Andy,
Have you every considered building your own 3d printer?

Hi JD,

Yes, but no, I've been watching the printers develop for the last 7 years or so, probably within the next three they'll be cheap enough and offer a high enough resolution worth buying for me.

What about you?

Cheers
Andy

I'll have to learn CAD first but I plan to teach myself this year with a copy of FreeCAD

Jd,

If I were you, I'd look into learning to use inventor or solid works.

Way more intuitive, better tutorials online and with the software.

Also if you use say inventor 2008 or solid works 2008 (same year revisions) then you'll be using proffessional software, but on computers with 5years technology.

I have just purchased another laptop for designing my models, a 2008 Dell M90, for £200, that's a top of the line laptop in 2008 for 3d Cad use. I have a slightly lower spec M90 currently, but it's now a dog to start up and shut down, when it's running it's still very smooth.

My logic for the laptop is that I have a lot of time money and effort invested in my 3d designs so 200 insurance policy seems a good idea, I can always migrate the files to the latest inventor edition in the future. If I did so, I'd need a new laptop costing my >£2000....

Inventor 2008, doesn't run on vista apparently, or if it does, it's prone to crashing.

Just my tuppence worth.

Cheers
Andy

Ah yes,
Trying not to hijack your thread but I only allow Mac or Linux in the house. I managed to put my fist through my work's laptop, a wonderful piece of kit from Dell that pissed me off one too many times. :shock:
Will have a look at TurboCAD to see if that is any good, any suggestions?

haha, yeah, one of the reasons I'm sticking with an old laptop is that I'm waiting for a Mac version of Inventor to be released, then I'll buy a new mac and craic on........until then I'm sticking with cheap upgrades.

i don't know anything about turbo CAD, but i'd have a look and check what's available for Mac's from solidworks, if I was going to start again I'd probably choose solidworks, seems that it is better supported in the world for off the shelf parts.

Ok, for those of you interested some further developments:-
I have found an avenue of cheap rapid prototypes, offering very high resolution, but for much cheapness......sound promising, the company batch run parts, so you have to wait a couple of weeks so there is enough orders to fill teh machine bed with the same material requirements...........but I'm in no hurry.

Anyway, I got some lovely 19oatcake drawings of the wire end adaptors for the chieftain ARV, CrARRV uses the same parts so I CAD them up, only slight difference is that the pin design has changed, so I fudged the design to mimic the new style.

Once I get my test prototype back from the company I'll commit to some more and prints.....I'm really excited! PS I am getting the tow chain printed (no not as shown and not the chain, just the connecting link and the pear link).

Hi,

Thanks for looking, the pictures are of the main winch fairlead for the CrARRV, really a mock up of the eventual styrene design, not really a design I can finalise at present as the model is back home and I need a few critical dimensions before I commit to it....

Anyway I did however go ahead with getting my fire extinguisher made, see pictures below.

Cheers
Andy
