My last trip to the city in July, I bought a brand new hp laptop, they set it up for me, I pick it up a few hrs later & go straight home (2,5hr drive). Open up the laptap, it's asking me for a password , phone the puter shop next day & they say they didn't set it up that way... so I have a brand new laptop sitting here that I can't get into.

Wink Re: LilGiantsConstrCO

i seen an add for an attachment that goes with a gopro and tripod that will follow a person from a distance like the beach and a surferon a wave and the person just has to have an arm band on. And you could put it in a dump truck and make some cool vids.

also from my last post you could use a humidifyer and dehumidifyer depem on moister in the air and result you want like less dust or mor dust lol

A little teaser of what I've been tinkering with the last couple weeks... it's almost done, maybe trials on the wkend.

Are you going mount that on the excavator and turn it in to a tunnel boring machine?

Looks real good so far Joe. How is the tunnel coming along? Weather is changing need to be indoors now. I finally got my cnc mill working and now am working on the cnc working for the lathe almost don with that. Now I fan focus on making some parts for the trucks. Ed

You betcha Kent! Vertical ripping just wasn't going that well, so I set my mind a few weeks ago to get this done!

Are you gonna live long enough Ed to ever start producing parts with cnc?

The shortest movie I made to date!

Awesome!! An underground miner!!! Next you'll have to set up a misting system, keep the dust down!!! I can see you having ripped apart a spray bottle nozzle hooked up to the garden hose!!! Cool idea joe!! Mine and grind!!!

Super cool ! So does this mean your building the worlds first scale continuous miner? definitely the best man for the task! Can't wait to see this in action.

I'm glad to see you decided to take this on yourself Joe! It looks like it will work awesome in the soil you have there. Better put an extra layer of safety glass on the 850's windshield though.

Hardest part of any job Reg is getting started

Sure looked good running on the bench... didn't it?!

... then into the pit for trials

This clay is sooooo sticky!!! it's ripping in chunks! and wants to walk up the wall.

I took out half the teeth (4 per row) & tried it, but it still wanted to grab too much & walk. Then I cut the remaining teeth in half (from 12mm to 6mm) that helped, but the clay just doesn't want to crumble or peel away... it's just too sticky.

I knew it from the start that that wide of cutting drum on each side would likely be too much cutting surface... I didn't want to hack up the original Blackwell axle incase it was a total bust of an idea... I'll check with RC4WD to see if I can get just the solid steel shafts that come out of the differential, so I can experiment with different widths of cutting drums... definitely needs to be half the width or less.

Motor got really hot too! need more reduction.

I'll have to ponder awhile, come up with a new plan... in the mean time just keep ripping & digging.

Is this going to be an attachment for the 850 Joe?

Leading edge of the teeth is 4mm tall.











Here's a quick vid showing the dismal result of my grinder idea

https://www.youtube.com/watch?v=mVqz9mOMUM0

Camera doesn't show depth very well... tunnel is about 3ft inward.

I wonder if it would be better to operate them like a screw? Maybe two sphere shapes spinning opposing each other like a twin screw on a boat. One motor per sphere or a gearbox between the two? At least it would try to crawl up the wall.

Joe- before you give up on that idea have you experimented with RPM. I'm wondering whether doubling your cutting speed would change the out come. I know changing wheel speed in the trucks changes how they handle in some off road scenarios, just due to the electric motor output.

Thumbs up Re: LilGiantsConstrCO

Can you try double the rpm and change rotation direction ?
Start grinding low and go up. it might work. just an idea.
Love your project .

If you give up on the continuous miner idea, make a drill unit for the hoe then drill and blast the material.
I have been thinking about how to do this when using my dragline but safety around spectators would be a problem if a shot went wild. In your basement there's nobody around to get hurt.

Forgot to mention about the video, Looks like You need more weight and power to be able to grind through that material. Are the spider gears still in the truck rear you're using. Get a worm gear drive so power is to both sides equal and like the other have said; up the RPM

The way I think after watching your vid of this in action I wonder if much larger drums with a few more rows of teeth might work better. when you look at the continuous miner machines they always have several rows of teeth contacting the surface at the same time.
Just my thoughts.
