Ha ha yea I know Ben :p

Thank you Neil . I really can't call it a cat with that tilt design it might just get the shade of yellow I grew up on mostly :)

Re: left over build (Cat 825C maybe )
 

You mean "faded" :lol::lol::lol::p Yah I know its a dozer design:D:D
Cheer's, Neil.

Dang Steve looking great!! Cant wait to see it pushing some dirt around!

Re: left over build (Cat 825C maybe )
 

Looking good Ihbuilder,

Can't wait to see this finished.

Regards Cam.

Re: left over build (Cat 825C maybe )
 

thinking taking it with me on sat., so I mounted a servo for steering and mounted the ROPs .

short vid with crappy cam since new cam giving me trouble taking vids :mad:I did have it on a stand ;)

Wow Steve its coming along great! Cant wait to see the blade and paint on it!

Re: left over build (Cat 825C maybe )
 

Love the feet!! Would be perfect for compacting after dozing my 1:14 scale short course truck track:)

Re: left over build (Cat 825C maybe )
 

Copper, truckmaker thanks a bunch

I've been giving this some thought :rolleyes: since the hi-tech 645MG does a nice job of steering , I might give the firgelli actuators a shot for the blade functions . Anyone know the actual length of the 50mm stroke pin center to pin center closed ? I got plenty other places to put that pump and valves in :D

Re: left over build (Cat 825C maybe )
 

I found it on their site :rolleyes: even the 30mm is to long and I'm not redoing that part . so back to plan A :rolleyes: Make it all tight in the cabin and engine house :rolleyes: .

Re: left over build (Cat 825C maybe )
 

Well that's too bad... an all electric set up would have been perfect for this lil beast, all the extra space could've been used for steel & lead weight.

I'm really liking those crows feet, hoping it's sooner than later when you make another run. ;)

Re: left over build (Cat 825C maybe )
 

right now it weighs in at 20lbs 9.5oz w/out the blade . the wheels are the majority of the weight (3-3.5 lbs a piece ), I suppose I could make them work . It's just moving the tilt boss on the blade back 10mm . Then I can fill the oil tank with BB's .

when I clean the mill out to run steel I'll throw them in the schedule .

Re: left over build (Cat 825C maybe )
 

Nice work Steve hope to see you in York. Ed

Re: left over build (Cat 825C maybe )
 

Hey Steve, which way did you have the phone oriented?
That would make a fun meat tenderizer, HMM, now I'm in the mood for BBQ :lol::lol::lol::p
Cheer's, Neil.

Re: left over build (Cat 825C maybe )
 

I was going to go with firgellis (don't worry I got another place to use them :) ) but time is running short for cabin fever :( . Cylinder production is almost complete so ,WTH , get er done :rolleyes: cap nuts and we good to go .

of course we throw nothing away stack is made from setup pieces and leftover tube . inside is a piston that had chatter in o-ring groves :(

Re: left over build (Cat 825C maybe )
 

How do you find time to build all of these wonderful toys? Keep it up!

Re: left over build (Cat 825C maybe )
 

This is a really unique model steve. I enjoy looking at something different for a change. Nice work as always.

Re: left over build (Cat 825C maybe )
 

I don't, I just force myself to take some time . A lot of these where started a year or 2 ago . I just resolved to start finishing 1-3 at a time before starting any new 1's this year :rolleyes:

thank you ,Tom :)
Ben (snochaser) helped with this idea .


lil update . "micropump" I modified will not cut it :( It seems they're not designed for hydraulics . So , rearrange everything AGAIN and put a jung setup I have sittin around and boy is it packed under the hood :eek:

thanks for lookin;)

Re: left over build (Cat 825C maybe )
 

Hey, Steve, looks like you hit another home run! How you got all that stuff under the hood is a magic trick in itself. Decals and glass will top it off. I really like the blade mechanism - just like the real thing.

You may have covered hydraulic cylinder making in another thread, but do you use single or double o-rings on the piston? O-ring for the rod packing?

Re: left over build (Cat 825C maybe )
 

:popcorn: Hope that can make me a bench to set on.

Re: left over build (Cat 825C maybe )
 

TY . I use o-rings on the piston and an X-ring for rod seal/wiper . On these I put a o-ring behind the X-ring for the rod seal/wiper . seams to work well so far .

we'll rough in with the loader and dress up with this . It pushes lose dirt OK but it wont be makin cuts . I hope the dirt is not to wet :confused: I wont get the cleaners made and on in time :( . I still have to put the loader back together :eek: I remade the lift cylinders to get the extra 2" of lift . I just need to setup and run the rams yet . 1st thing in the morn .
