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.
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)
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 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. |

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.

I don't get on the forums much anymore, but when I do I always check back on this tread. Thanks for posting.

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!

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!

Re: PC1800 Front Shovel (1/12)
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

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. |
