New member. Building D8
 

Good day to everyone. Just intruduced to rc construction. I have been involved in rc racing and airplanes for the past 25 years. Seen li giants you tube page and brought back thoughts and dreams of when I was a kid. Thought it would be very net to have working rc construction equipment. I think we all love construction equipment when we were kids.
I chose the user name fired up because I and very fired up to build a project and have decided to build a d8. Now gathering parts and pieces. Thanks to some of the threads here for info. I will post some pics as I build. Thanks for the inspiration and great builds
Patrick.

Re: New member. Building D8
 

Had a chance to get some parts started today 5 out of 18 giude wheels done

Re: New member. Building D8
 

Some parts in but weather bad here in New Brunswick so will have to wait to get them maybe first of next week. Going to try to get to shop today and turn more guide wheels. To answer your question on which type i am building its going to be a hight track one. this is the picture from the D8 brochure that i used to inlarge to work by. Hope it turns out. I am using alot of ideas that RCLogger used in his build. thanks for the great ideas.

Re: New member. Building D8
 

What scale are you building?

Re: New member. Building D8
 

I am building it around 1/14. Hope to get my parts that I ordered tomorrow. Start turning the wheels for tracks.

Re: New member. Building D8
 

Fridays here and gone. Got tied up in local volunteer fire deptment business. Never got in the shop. I have lots of parts. Got motors from servo city attach ment chain ordered lots of round stock on hand just need to get at the lath. Has any one used grease to tighten the track. That's what my plan is right now using 5/8 round stock going into 1 3/4. With 2 1/2 wheels at each end. Would like feed back on the grease idea. Thanks.

Re: New member. Building D8
 

Grease is messy I use springs and 1/4 inch bolts in a piece of pipe, I can show you a diagram.

Re: New member. Building D8
 

Glad to have you join us Patrick! Looking forward for all the updates on your build!

Re: New member. Building D8
 

Had time in the shop last couple days. Finished the rollers for the under carriage. Started to turn the bigger wheels for each end of the tracks. Very slow with my small lath. The pieces that I'm using are 2 3/4 and all most to big for my lath. But fit. I am turning them down to 2 3/8 same size as the sprockets that I have. Hope to get more done this week.

Re: New member. Building D8
 

It's been awhile but I am back at this build. I using a 3/4 steel plate for my base to add a low center of gravity. I thought about using grease but chose to use a spring to tension the track. Here are a few picks of what I have done

Re: New member. Building D8
 

As u can see this build is taking ideas from many of the same builds on this forum.

Re: New member. Building D8
 

More pics.

Re: New member. Building D8
 

Here's how I am making the track adjuster.

Re: New member. Building D8
 

One spring might not be enough

Re: New member. Building D8

Comparing against plan

Re: New member. Building D8
 

Coming together.

Re: New member. Building D8
 

Looking good. Just watch that Cat drawing, they are not totally to scale. I think this is done on purpose. Just a heads up.

Re: New member. Building D8
 

Thanks for the heads up. I am cross referencing measurements also. Has any one ever used the hyd pump from rc4x4? I will post more pic of my progress soon

Re: New member. Building D8
 

Welcome to the forum:) Great start, looking forward to seeing the progress.

Re: New member. Building D8
 

Here's a mock up of cab. Still not sure if am using electric actuators or hydraulics. How do u hook up two speed controllers to one receiver ?

Re: New member. Building D8
 

Sabertooth dual motor controller

I vote for hydraulics, much faster, more realistic movements than electric actuators.

Re: New member. Building D8
 

Had more time to work. A cnc would be nice. Lol table saw and jig saw is slow.

Re: New member. Building D8
 

Body work.

Re: New member. Building D8
 

Small parts.

Re: New member. Building D8
 

Riveting it together.

Re: New member. Building D8
 

Once everything fitted will take apart and cut my windows. Looking for sujestions on plastic for windows.

Re: New member. Building D8
 

Has any ordered from premcon. Also wondering what duty would be like from Germany to Canada ?

Re: New member. Building D8
 

There's no duty. You'll pay 5% GST & whatever your provincial sales tax is when you receive the parcel.

Payment is usually done with a bank wire, but you could ask if they have paypal or other.

Re: New member. Building D8
 

Great thanks for info. I have decided to go hydro. Ordering from premacon pump fittings,hose extra. Here's what I've done today.

Re: New member. Building D8
 

I'm curious to know what motors you went with, and controllers? I'm building a d11 and haven't decided what setup to go with. So I'm always trying to figure out what others do.

Re: New member. Building D8
 

I am using the same motors as rclogger. Watched his videos and they seem to work very well. I am using the sabourtooth 2/25 Controller. I have had it hooked up and seems to work really good. I weighed my d8 with out electics hydraulics and no blade and it was 36lbs. I figure when done be around 50lbs. Hydraulics are ordered hope to see them in a couple weeks. I have most of the building done. Time to tare it apart to get some paint on it.

Re: New member. Building D8
 

Nice job on the dozer build..keep up the good work!!
