Wow that's great to hear at least for you!

Re: PC1800 Front Shovel (1/12)
 

I did manage to spend some time on building the hydraulic tank, it is 2" x 5" x 14" long and if filled to the top would hold about 2200cc, hoping to have just under 2000cc in the tank when in use.

Still need to make a few changes to the intank strainer but this will the general idea
(#60 stainless steel mesh , really wanted to use #100 but couldn't get any)

I welded a baffle plate inside the tank, the idea is to help push air bubbles up and away from the suction side, not sure if it will be of any help in such a small tank but thoght I would try it anyway....

Here is the tank before welding....

After welding I used this small valve to pressure check the tank for leaks...added about 25 psi of air and sprayed the tank with soapy water and looked for air bubbles...all good!!

Re: PC1800 Front Shovel (1/12)
 

Oh, like that tank, looks so good and with all those featchers built in it must be a winner.
If/when I will have to rebuild mine, some of your solutions will be copied :)

Re: PC1800 Front Shovel (1/12)
 

Good to hear everything turned out okay for you. Glad your able to get back to work on this. Very nice work!!!

Re: PC1800 Front Shovel (1/12)
 

Very glad that you did not suffer any big damage - and prayers for those that lost everything. Your hydraulic tank has more features than some I've seen on real machines and the shovel is looking really great.

Re: PC1800 Front Shovel (1/12)
 

Great idea for the tank filter and nice work. You do come up with some great ideas. Ed

Re: PC1800 Front Shovel (1/12)
 

Nice to see your able to carry on with the build! She's really looking like a mean machine coming together.
Tank features are very cool and love it. One thing that came to mind though, it's hard to tell in the pics but how thick is the tank walls? Just wondering about cooling factor..... Then again, such a large surface area heat retention shouldn't be a problem?

Re: PC1800 Front Shovel (1/12)
 

Making some awsome progress ..this machine is build to last and some great features with the tank as well ...to darn bad you are so far away ..Btw sure glad you made it though that devastating fire ..so many people lost everything ..im sure you knew many ..my heart goes out to them

Re: PC1800 Front Shovel (1/12)
 

Thanks Dan!!

Thanks!! It sure is nice being able to continue working on this project...there for a while I wasn't sure if that was ever going to happen!!

Re: PC1800 Front Shovel (1/12)
 

Thanks!! The tank filter/screen design was really just a fluke, was originally thinking of just soldering the screen to the outside of the copper tube but luckily found some brass tubing that fit really snug against the screen when inside the copper tubing, sometimes luck is just as good as skills!! LOL

The tank wall is 3/16" thick, the reasons for it being that thick is to be able to cut pipe threads directly into the tank wall....the original design had some threaded holes on the side of the tank as well but ended up changing things around a bit and just decided to use the same thick wall square tubing....already had it so hey...got to use what you got!! Hopefully heat retention doesn't create any problems, I think it would take a long time to heat everything up enough to cause any troubles...hopefully! Lol

Re: PC1800 Front Shovel (1/12)
 

Me too!!! We do know a number of people who lost everything!! We are very fortunate to still have a home etc!!!
The features in this little tank might be a bit overkill but hey...why not!!

Thanks Ken!!

Slowly making some progress on this build, hopefully one day it will get completed...lol...I here ya on the distance gap, at least there are a few people in this hobby near you, must be nice!!:p :)

The fire has impacted everyone up here, some more than others.....some people are rebuilding and some are not. I know a number of people who never lost anything in the fire but have still decided to leave town...only time will tell how much this affected us all.

Re: PC1800 Front Shovel (1/12)
 

Got started building the boom...finally...started by laying out the sides and cutting them in the band saw.

http://i1291.photobucket.com/albums/...ps43d5tc4r.jpg

http://i1291.photobucket.com/albums/...psiibxtstj.jpg

After drilling the pivot holes I bolted on a couple of heavy washers (turned on the lathe) that had the proper diameter/ radius and then used the belt sander to grind the radius on the ends of both plates, the thick washers act as a guide and or stop point while grinding the rads by hand.

Hurry up dad we need her down here to load rw's 785
The little excavator just won't do

Re: PC1800 Front Shovel (1/12)
 

Really trying to hide any welds, so most of this will be welded on the inside. Only the longer top section will end up being plug welded from the outside.....so I milled a small shoulder on the edges of all three outer plates, doing this also leaves a small lip on all the edges much like the real deal.
The small slots on the front of the bottom plate are to allow the front pivot/hyd. mount plates to be welded on the inside, as well as locate them... (hopefully this will all make more sense later....lol....just need to make a few more parts of the puzzle)

Re: PC1800 Front Shovel (1/12)
 

Lookin good KP! Sure is great to see you back posting updates. How's the rebuild of Fort Mac going?

Re: PC1800 Front Shovel (1/12)
 

What, prey-tell, do you use to draw on the metal? A sharpie isn't the best thing for me. Do you score it with a scoring tool?

Re: PC1800 Front Shovel (1/12)
 

This is looking awosome, i can't wait to see how the arm comes together

Looks like he covered it with a layout fluid like Dykem and scribed the markings into it.

Re: PC1800 Front Shovel (1/12)
 

Thanks Reg....the rebuilding has slowly started, the clean up took a long time and being so close to winter not many houses have been built yet, should see much more construction starting next spring.

Re: PC1800 Front Shovel (1/12)
 

This is what was used to layout the lines etc.....

Spray on the layout bluing, scribe the lines, when you are done the part spray on the remover and wipe it off with a rag. Here are two brands that make both the layout fluid and remover, I find that the Osborn brand is better but both work well. Hope this helps...

Re: PC1800 Front Shovel (1/12)
 

I see. Funny how something so massive can be completely forgotten about by the media just a few months after it happened. We haven't seen anything on the BC news about it in a long time so I wondered how it was going.

Re: PC1800 Front Shovel (1/12)
 

Good to see you making headway again on this project Kornell, always impressed to see how you do things as you do them. ;) :cool:

How heavy do you suppose the arms/bucket will be built from steel?

Re: PC1800 Front Shovel (1/12)
 

Thanks Joe, I have most of the parts made for the boom and the total weight is 14lbs, once everything is in place etc I'm planning on milling away some of the unneeded material thickness in places where no support is needed to help bring the weight down. The full scale boom is 26000lbs, 1/12 scale is 15lbs, so if nothing else on this build is to scale at least the weight should be close!! LOL

The full scale weight for the boom, arm and bucket is 39.4 tons (78800lbs) 1/12 scale would be about 45lbs. The total weight of the full scale machine is about 400,000 lbs' 1/12 scale would be about 231lbs.

Re: PC1800 Front Shovel (1/12)
 

After filing the slotted holes in the bottom plate the hyd./pivot plates can be inserted and welded from the inside....and for some reason two more slotted holes magically appeared...LOL...seems that someone made a few extra, again!!

I very much enjoy watching this build come together. A lot of the things you are doing I don't understand but it becomes clear later on. Very nice work!!

Thanks!! It's always nice to get feed back from other members on here...I appreciate it!!

Funny you should mention that some things I do you don't understand at first....your not alone, I also don't understand some of the things I do...lol...I don't know about any of you other scratch builders but for me it seems that you get an idea in your brain and just have to go with it, good or bad, only to ask yourself after it is finished...why did I do it that way??....when there was a better/easier way to end up with the same end results...lol...I guess it's always easier to figure out when you have something to actually hold in your hands and or see compared to just a thought in your head, but hey I guess that's just part of the fun and challenge of a scratch build...

Re: PC1800 Front Shovel (1/12)
 

Finished making the inner pivot/hydraulic mount plates.....sorry, not much of a progress report, but hope to get some time to work on this through the holidays.

Finished the lower hyd. mounts on the boom....really wish I had a new 3/16" end mill, the two I have are dull and duller....lol....so this ended up being painfully slow but thankfully I did manage to get the slots done.

I'm going to try make this style of pin keeper...think this will be fun to make by hand (not)...might be a bit of filing invloved with making these...lol...The keepers and pins will be made of brass and then soldered together.

http://i1291.photobucket.com/albums/...psfnau9ccs.jpg

Re: PC1800 Front Shovel (1/12)
 

Got a bit more done on the boom....cut out the section on the ends of the top and bottom plates, should be one big radius from side to side but I decided to square it up instead. Also made the small lifting lugs...funny how the small parts take so much time to make, hopefully the end result and appearance will be worth all the time.

Re: PC1800 Front Shovel (1/12)
 

Had to read thru this build again. You have comed a long way and shows a lot of building skills. This is a true watch and learn build!
/Dan

Re: PC1800 Front Shovel (1/12)
 

You're right. Small details do take time but add so much to the overall build. Those lifting eyes are perfect. Now you and some of the crane guys can actually field assemble your excavator, after being hauled in by 7 or 8 lowboys. That would be a hobby show on its own!

Used a small sanding disc on a die grinder and a guide with the proper radius to finish the keepers after rough cutting them on the bandsaw, not the most accurate way to do it, but it does work fairly well.

If you hadn't showed us how you did it KP, I'm sure most of us would have assumed it was done cnc, top notch work as usual :cool:

Re: PC1800 Front Shovel (1/12)
 

Thanks Joe!! CNC is the way to go, much cleaner build and 10-20 time faster!! This making parts manually is painfully slow!!

Almost finished all the parts of the puzzle for the boom......hopefully I can get this "mess" all welded together, inline and without shrinking the pivot bore size, time will tell.
