LINE BORING EXCAVATOR

[@richardselous7219]

Brilliant job. I've done one of these and thoroughly enjoyed doing it. I notice your boring bar is hollow. My set up has bearing blocks to hold the bar true to the bore, but just looking at your set up, i really like the set up you have. The bar holders would work perfectly as a steady when dealing with harder material, taking bigger cuts or even just for traverse speed. It could go on the end to steady the bar (space permitting). Very good video, keep them coming

Nice work & quite an ingenious set-up for the boring operation ! The old Milwaukee mag base did a good job driving the boring bar too.

Looks like a professional approach in the field. Great work. Thanks for sharing

pro trick: watch series on kaldroStream. Me and my gf have been using them for watching all kinds of movies these days.

[@alexliam9786]

@Samuel Beau Definitely, I've been watching on KaldroStream for since december myself :)

[@traviszahir2699]

@Samuel Beau Yup, I've been using kaldroStream for since november myself :D

GREAT... but instead of welding bits on, I think baling twine would be more authentic, with a few rusty 6" nails and a chicken sitting on some eggs and a whisky still smoking in the background 🤔👍...

Damn nice. First time I ever saw grease grooves in excavator/backhoe bucket pivot pins. Sweet. All we were ever able to do years ago was to break the cylinder down, take the rod to a shop (like yours) and have it done. Most often repairs were for catastrophic breakage, damage to the rod or leakage rebuilds.

+Doug Bourdo Thanks

What kind of boring bar? Looks like an old boring set up for doing diesel engine blocks. We had an old kwikway bar and just use the bar and feed unit to bore with. Boughts some bearings and it work great. The feed unit was light duty wouldn't feed vertical. Great for buckets!

[@THEIRONWORKER]

It's an old Ammco boring setup . I can't find any info on it Thanks

[@patdexter9188]

Hmm, looks alot like the kwikway setup we had. Used it to do rod mains and cam journal's. I like the rack feeder on it, old school!

[@AJ........]

Hey nice job...could you please comment what those 3 prong expanders are called and where I can get some?

[@THEIRONWORKER]

I don't know what they are called . But they came with my line machine . Some line borer use cones to center the holes with Hopes that helps

[@gallant19650]

nice set up but complicated,we use 2 flange bearings for this type of work witch takes me about 3 h .....welded and bored but i still love that set up

[@miguelcastaneda7236]

well done sir

[@metalworksmachineshop]

Nice work, is that setup your design?

[@THEIRONWORKER]

It Is not my design but it is made by Ammco I can't find info any where on it . The set up is mine Thanks

[@Reftravun]

Very interesting to see your line boring setup in action. Couldn't quite make out from the video what type of cutter you used. Was it brazed on carbide?

[@THEIRONWORKER]

It is a carbide cutter that has a round shank so my bar is drilled out to .375 to hold the cutter and set screws hold and push out the tool bit Thanks

[@cwmayes1580]

Did you make the pins? What did you make them out of and did you have to heat treat them?

[@markmyword1742]

What's the tolerance on a job like that as far as size?

[@THEIRONWORKER]

With this setup I can do about 4" dia. . I'm using a 1-1.4" bar

[@THEIRONWORKER]

no heat treatment & stressproff shaft

[@donaldkiefer9718]

ware can i get 2 speed feed for boring bar

[@dongguanportabletools7601]
