Re: Fumotec 490
Long paint curing times have majorly slowed me down :( so disappointed with how long i've had to wait, even still parts are dry but if handled too long will leave a mark.
All painting done in my loft which is dry and about room temperature, it even has a window which gets direct sun light through it Anywhere here's where I've got too still loads to do http://i721.photobucket.com/albums/w...7F836E1B05.jpg http://i721.photobucket.com/albums/w...184DE4CEC5.jpg http://i721.photobucket.com/albums/w...B4E2547C5B.jpg |

Looks great!! Keep us updated!

Re: Fumotec 490
Nice model and will be a good runner I think.
This type of valve is under concideration for my rebuild now. Anyone that can get feedback how they perform. What size of pump did you go for? http://i721.photobucket.com/albums/w...A404A47D21.jpg |

Re: Fumotec 490
Only valves I'll use, haven't had any problems with those valves and pump. A lil' pricey but superior quality!! I'm sure you will find out :)

Re: Fumotec 490
It lives again! Only really the cab and stickers to finish it of. I have some of the smaller detailed parts like hand rails to fit if i decide to put them on or not?

Re: Fumotec 490
Ooh, It's in pieces & unpainted again. What went wrong with it?

Re: Fumotec 490
Oh the humanity...
What's the new color going to be? |
Re: Fumotec 490
I had a terrible time with paint, it never really cured and could chip off with the slightest knock. So after much thought I decided to strip it and repaint it using an airbrush instead of spray cans.
So far I’m really glad that I’ve done it, there was things I wasn’t happy with the first time round so this has given me a chance to repair/fix these which will hopefully improve the machine. Anyway it slowly goes back together. Still loads more painting to be done https://i.ibb.co/pw1pYjx/52-C8-B5-C6...75-B5536-E.jpg https://i.ibb.co/bNc3zqP/373-FBF13-E...88-EA8-E01.jpg https://i.ibb.co/zmBQ2zF/2-EAA001-B-...1-C86578-D.jpg https://i.ibb.co/wgmz6xy/9-C9-F52-B7...753-FA54-D.jpg |
Re: Fumotec 490
Much better!!! I can tell the difference. Any videos of the rotating bucket?
|
Re: Fumotec 490
Looking good Calum :cool:
Have you used it lots? And yeah, how's that rotary screener working for ya? |
Re: Fumotec 490
liftmys10 - thanks I'm super happy with how its turning out.
Joe - sadly I have not used it since I originally painted it! Disgraceful I know :( I will aim for completing it this year for some summer digging. I cant comment on the screen either, as its yet to touch any dirt... Been distracted building and painting other trucks, but I should be back to this soon enough |
Re: Fumotec 490
A screener showed up in the mail Friday, pretty simple bit of kit to put together, Frank does good work. :cool:
|
Re: Fumotec 490
Note to self - Do not try and paint 2 projects at once!
A shed load of sanding, filling, primer, paint, anger, more sanding, more filling, more painting and some clear coat later progress is being made! Currently down to the last 4 main items, everything else is hanging up curing and waiting to be fitted. Alongside a Tamiya Scania which i'm building :cool: https://i.ibb.co/3hrVH6S/IMG-20190513-214908.jpg https://i.ibb.co/MkkJSfX/IMG-20190513-214937.jpg https://i.ibb.co/C51qHCw/IMG-20190513-214950.jpg https://i.ibb.co/MPThKxF/IMG-20190513-215002.jpg https://i.ibb.co/8rxT9Wg/IMG-20190513-215010.jpg |
Re: Fumotec 490
Finally the painting comes nearly to an end, only the cab and interior parts left to do :rolleyes:
https://i.ibb.co/hFqy4TH/IMG-20190519-091321-1.jpg https://i.ibb.co/jDXgQhZ/IMG-20190519-091337.jpg Assembly begins, far easier this time around as I know what parts I struggled with the last time - these hose fittings were a nightmare before because I installed the hard pipes then put the plastic hose on. Trying to tighten these connectors without damaging anything was near impossible. Better results this time :cool: https://i.ibb.co/Dp93ybq/IMG-20190525-222738.jpg https://i.ibb.co/5WTVJsc/IMG-20190525-222810.jpg https://i.ibb.co/HVdSwHw/IMG-20190525-222828.jpg https://i.ibb.co/VW3jc26/IMG-20190525-222856.jpg https://i.ibb.co/wQSX2SB/IMG-20190525-222957.jpg |
Re: Fumotec 490
Looks great in the new paint
I love the tiny castle nuts, are the bolts crossdrilled yet? |
Re: Fumotec 490

Yes drilled already, waiting on some 1mm split pins to turn up Calum |
Re: Fumotec 490
A little more done tonight
Started of with the hard pipes - the screws that hold the pipes on was a nervous job, trying not to scrape any paint but I got away with apart from a little mark. Then all the pivot holes cleaned out from paint, the ram was put into its place and the stick mounted to the boom :D https://i.ibb.co/ZggMHzf/IMG-20190527-210707.jpg https://i.ibb.co/Sdvg1Bp/IMG-20190527-210713.jpg https://i.ibb.co/7jDRQwh/IMG-20190527-210718.jpg https://i.ibb.co/cTMmZjP/IMG-20190527-210725.jpg Calum |
Re: Fumotec 490
Well it lives again :cool:
Everything connected up, oil in the tank, bled it up and checked for leaks - so far the only one was a return pipe to the tank which was a quick fix. I've been painting interior parts in the meantime - a mixture of airbrushing and hand painting https://i.ibb.co/Qb1pVkJ/IMG-20190616-142558.jpg https://i.ibb.co/rt33Xy0/IMG-20190616-142603.jpg Also last weekend got the final coats of yellow on the door and cab, those were clear coated and left to harden up. I've given them a light grey colour inside. Next job will be to glue the windows in and mount the door https://i.ibb.co/jWd2Jb9/IMG-20190616-142526.jpg https://i.ibb.co/V24fS4Q/IMG-20190616-142529.jpg https://i.ibb.co/vB3SwG4/IMG-20190616-142536.jpg And yesterday it was time to test it out, just some light digging whilst I set pump speeds and pressures. I mainly just wanted to see how a trial went, lasted nearly 1 hour on a 5000mah battery which I'm happy with :D Then as the battery was coming to an end my swing stopped working :rolleyes: soooo thats was the end of that, packed up and back on the bench I removed the motor and gears to find a grub screw loose... A dob of Loctite and back in it goes! https://i.ibb.co/hgtjy4m/IMG-20190615-131247.jpg https://i.ibb.co/jLmFf9Z/IMG-20190615-131254.jpg https://i.ibb.co/b5gTNxN/IMG-20190615-131257.jpg https://i.ibb.co/GpGG2MZ/IMG-20190615-131302.jpg https://i.ibb.co/XV8Ph1d/IMG-20190615-131306.jpg |
Re: Fumotec 490
That looks fantastic!

Re: Fumotec 490
Thank you, hopefully when the windows are in it'll look a little more finised

Re: Fumotec 490
A few pictures of my cab, the window edges painted black before glueing the windows in.

I still need to finish this off the black edging sticker supplied with the kit https://i.ibb.co/BnVVP5x/IMG-20190620-195532.jpg |
Re: Fumotec 490
Upgraded my Graupner gimbals for 4D versions, will give me the ability to use the aux functions now. A fairly cheap and simple upgrade although fairly nerve racking opening up a graupner radio :rolleyes:

Re: Fumotec 490
Those gumball controls look like they'd be nice to have. Much easier to use than the stock sticks, I'd think.

Re: Fumotec 490
Looking good Calum, you have everything working to your liking now?
|
Re: Fumotec 490
I think so Joe, haven't got many hours on it so far. My only problem is the stick cylinder - I can't decide if its faulty or not. It doesn't seem to have much power but maybe I'm expecting too much from it?
Whats the digging power of your 490 like? Calum |
Re: Fumotec 490
I have my pressure turned down to 18bar, I dig in cultivated soil & it won't pull the model off its perch... if the stick with is pulling the model around, the pressure is too high... but with 14mm cyl bores on this model I don't think it's possible anyway... what do have your pressure set to?
Keep in mind raising/lowering pressure will greatly affect reaction speed too. |
Re: Fumotec 490
It's set to around 22bar, I'm not trying to dig up my garden or anything extreme. Just I feel it should have a little more power?
I don't have anything to compare it so maybe it's okay. Certainly digging sand it managed easily Calum |
Re: Fumotec 490
Adjustable by remote?
Nice details, btw :) |
Re: Fumotec 490
Yes, servo operated - bit of head scratching trying to get it to run smoothly.. :rolleyes:

Re: Fumotec 490
