I walked the JD850 out of the hole last weekend to fix the rc quick coupler, installing a new esc that has a built-in adjustable current limiter, motor draws too many amps (when the locking pins reach the end of travel) and it shuts off. Got from HeyOK Performance out in BC... thank you Kalle for putting me onto this guy.



Al Jackson of HeyOK Performance website. His products were designed moreso for the rock crawler world of rc, but some of his products will cross over into our realm as well.

And here today again, the JD850 coming out of the hole to travel back to workshop... it's a 15minute drive





Having just gone through the experience of the brushless pump motor bearings going out on the JD450, the JD850 was making a similar noise... with the motor removed, I can see the bearings are still intact, but feel dry & rough. This motor is 5yo - no doubt greater than 1000hrs use.





I have a Fumotec WA500 wheel loader that I got spring of '14 & have yet to put together... I just got some replacement parts for it in January b/c I robbed from it last summer to fix the B50 adt... now I'll steal the brushless motor from it & have the JD850 on it's way back to work in a couple hrs... it's good to have spare parts, especially when the parts store is on the other side of the globe!

Yesterday here was another whiteout with high winds, a good day to spend inside! I cut out all the bench tops within the tunnel's length & practiced cutting a flat angular grade, this slope is 20 degrees (thanx Cooper for the clinometer app, sure comes in handy ).





From where the hoe sits now, digging down 10 inches will give me 62 inches from ground level to cement header and angle up 12 degrees from there... I have a few doorways in my house at this height, I'm use to ducking anyway. Plus to go down another 12 inches would add another 5 foot or more to the ramp length... more digging yes, but there'll be a big enough hole in that room as it is.



A quick vid of the process... swinging 90 at this slope, the sump ran dry & lost some oil out the vent hole.

Not too much accomplished in the last month... weather is too nice outside to spend much time inside.

Quite a bit of rain in June & just not having any luck getting a hold of eave trough guy, the excess rain was starting to wash the dirt away from the tunnel wall laid down this sheet of plastic June 27th & no more water problems since.





You can see the eroded the cement pillar, 2nd from the end wall, better view of it in the vid. Month ago I propped a sheet of pws against pillar & shovel a lot of dirt in behind, not all of it stuck though. Those cement pillars go down 12 feet, so no worries of it moving.

The orange string you see (baler twine), once I get the bottom dug out, set the string in place so I have something to eyeball as I cut the ramp to a more favorable grade, about 12 degrees.





Starting the 3rd row on the pile



quick vid from today's activities

Started today cutting final grade on the ramp, 1" in spots to 1' in others... it sure would've been nice if that grinder idea I had last yr would've worked better. Hopefully I don't create too many potholes with the ripper.

What I've been working at lately, getting the walkway dug out. I can walk through on the ramp without bending over much, which is handy that the weather is now -20's







The camera doesn't show depth perception very well, it may look rather flat, but it's a 35 degree decline leading into the tunnel entrance.

Finished the dirt ramp a few wks ago, this all I have left to dig out for the walkway, 3 x 3 x 2.... less than a cy. Where you see the trench line leaves 24" for the last two stairs that I'll hand dig to the correct dimensions. Then stick my diesel blast heater down there for a week or two to dry out the tunnel walls & stairs cement hard.



These couple pics was last weekend.





And then this morning's 3 lipos worth of rip - dig & pull it back to where the 850 is able to swing 180.











Another 20 trk loads ready to haul out



The last of the tunnel dig will be to cut the hump out of the entry to make it about a 14 degree decent, I'll still have to duck myself to walk through.

Thanx Taco, much appreciated

Another cold snap this week with temps close to -30 makes the tunnel a deep freeze! Moving operations to ground level where my diesel heater is at





Started out with Scale Art loader to push in an entry ramp, but the big lumpy dirt & somewhat packed was slow going.



Ahhh, it's so nice to drive this out



The 850 makes short work of throwing dirt to the side.



Now used the track loader to bulldoze dirt into place & start screening









Another chinook coming in on the wkend, head back to the tunnel dig then.
