Wow ! I'm so jealous ! Very clever setup, impressive. Keeping this hacksaw table jig in a corner of my mind, maybe someday ...

You’re inspiring me to make a ripper. Not there, but closer. My concern is the necessary hardness to withstand wear on the serrated cutting edges.

I’ve build a tree puller (fun to make) so welding & fabrication isn’t lost on me.

As for portable band saw setup, I use one from SWAG. It’s a stand that can quickly be detached for mobile use. They have neat stuff.

Do you have a post with pictures of your tree puller? I would like to see it very cool. I will have to see if I need to temper the front of the ripper with a torch. I did see couple of others that did not do this they just cleaned it up after every few uses. I thought about welding on the front teeth weld seems very hard.

I saw the SWAG table but I wanted to be able to chop with it also. So far I have used it chopping a little more than standing.

I did chamfer the new pin ends that I made. That really helps a lot.

A ripper and thumb are ALMOST visible on my project list; here's a crude paint sketch of my tentative tooth plan, with a smaller than industrial size hoe you'd need to scale it accordingly... Steve

That is funny. I just bought a set of AR500 targets to make a shooting tree. (another welding project) I was wondering if anyone had used some AR500 on their ripper.
Do you know of anyone that has used this design? I would love to know how it performs.

"Do you know of anyone that has used this design? I would love to know how it performs."

Not exactly, just looked at a LOT of rippers - several with teeth, some so aggressive the hoe would probably pull the rest of the tractor over on top of ya :eek:

Best I can offer is - I've built a lot of projects, and MOST work as I envisioned (some after version 2.0, most with no, or minor, tweeks) - been retired since 2013, last 35 years as instrumentation tech in heavy industry (rare metals), last 10 running a rotating shift maintenance crew with 2 electricians, 2 millwrights, 2 pipe fitters, 2 weldors, 2 machinists, and 1 instrument tech (me) - to a man, when I put in my retirement papers (I wuz already 67) they did their best to talk me out of it; they all knew they'd never find another "leader" that'd work as hard to keep them safe AND actually know what they did, make actually USEFUL suggestions, etc...

That is the nice thing about this forum. There are people with lots of great backgrounds and real work experience.
That’s not my background I was an Electronic tech in Navy then I worked in Information Tech and now an IT consultant/programmer.
I do research a far amount for my projects. These are my biggest welding projects so far. This is the first time I have dealt with ½ thick and 3/8 thick metal for my projects.
I will be trying out my ripper soon but if it does not perform as I want, I will be changing it. I have a fair amount of material to work with. It is always good to hear other ideas.


My ripper is ½ thick I probably could use scrap AR500 for the teeth. One of the target places might even sell some scrap cheaply.

Sounds like we had similar backgrounds for at least PART of our lives; I spent 4 years in the Army Security Agency back in the '60's, cold war electronic snooping stuff - graduated tech school top of my class, agency needed 2 more instructors so spent next couple years teaching, then a year TDY as a trouble-shooter all over the place - when I got out, first job was with Memorex - video tape division first, later on a design team in their digital development lab (when hard drives were same size as your washing machine) - started my own company (moonlighting at first) in TV and recording studios maintenance/repairs, moved to Hawaii for a couple years (Startup company, video/audio sales/service, calibration lab) then back to Oregon shortly after my dad died, nothing in Oregon paid crap in electronics at the time so found a job in instrumentation, etc...

Probably the main diff between us - when I was 9, Dad bought a little 1 acre piece of raw property to build a house on - it sat right on the road, but on a cutbank so the property was about 7 feet ABOVE the road. He found a used "mini-cat", little baby dozer with a 9 horse crank-start motor, mechanical 3ph, mechanical blade, found a used "slip" - think "wheelbarrow without wheels, no front tip-up, longer handles, pivoted cross-bar with a hole for a chain - one person drives the tractor, other holds the handles down and tries NOT to get flipped over it :eek: - Since Dad outweighed me by about 90 pounds at the time, I got to drive - Beginning of an addiction :thumbsup: - Next door neighbor had a small logging operation, saw how much fun I had with the TOY cat, next day I got to drive a D8 up in the woods; addiction now fully formed :rolleyes:

Lot MORE water under THAT bridge, but I'm ALREADY good enough at sidetracking threads :laughing:...Steve

" I probably could use scrap AR500 for the teeth"

Good luck tryin' to GRIND any of that; I got away with torch cutting on one job replacing wear strips on my 2' hoe bucket (AR400) - about 12 years ago I had the strips plasma cut by steel supplier, then 7018 stitch welds/heat-bend with torch, stitch, repeat... Before I started, I didn't like the edges of the strips. Too sharp and rough, and I didn't think it'd be fun to bump an elbow on the bucket when walking around the tractor, so I grabbed my 9" grinder, clamped 'em in a vise - it took about 30 minutes PER STRIP to put enough of a chamfer on the edges to even NOTICE...

That's why, on that sketch I did I briefly mentioned how I'd do the "dominoes" - first thing would be to set my "flange wizard" to cut @ 45 degrees, and "rip" the long way on a 3" wide strip; THEN I'd cut however many dominoes I needed off that beveled strip, and mount the point of each bevel AWAY from the ripper (see sketch).

Doing it that way would save trying to cut a dozen or so LITTLE pieces at an angle, cause I doubt you're gonna cut that stuff with anything LESS than O/A or plasma, unless you have access to a laser or water jet... Steve
