Re: Drilling Hard Rock With Carbide

It's just a matter of what spacing you can get away with, and sometimes, how many extra holes you need to line drill between the holes you wedge.
All dependent on the rock....

Re: Drilling Hard Rock With Carbide

Makita SDS is a good hammer drill. Don't expect your chert to drill as easily as concrete. Concrete is about 4000 psi, chert, depending on the flavor, is roughly in the neighborhood of 35,000 to 65,000, if I recall correctly. It won't take long to figure out if the SDS has enough blow energy to dril...

Re: Drilling Hard Rock With Carbide

I've drilled miles of quartzite....quite similar, but generally harder (a lot) and more abrasive. Talkin' about rock that is 50,000 PSI and harder. Regardless, plain rotary won't cut it if it's hard. Percussive/rotary is what you need, like your hammer drill. As far as hammer drills....yes....we use...

Re: wheel pullers

All my OTC pullers, and OTC wanna-be's are fine thread, not acme (I have some cheapies and who know's where they came from models too) . Hard to get better than OTC. Quality stuff. Fact is, out of a couple dozen pullers, the only one I have with acme threads is a vibration damper puller I got from A...

Re: Blast cabinet liner

Ahhhh....OK....I get what you are gettin' to.... :) As far as bed liner....the stuff that comes in a spray can, won't live a long time. I use it on my old swamp cooler to stop the leaks. Works, but I have to respray it every couple of years. (I keep threatening to get a new cooler....and then end up...

Re: Blast cabinet liner

I'm confused.
I have a blast cabinet, and it's not lined. I have worked with many, on different jobs, and they weren't lined.
I also worked at a dealer, that sold Empire cabinets. None were lined.

Or am I missing something here???

I'm not familiar with these terms. What is this "rust" and "humidity" you guys are speaking of? For the Valley of the Sun..... -The way it used to be, when Phoenix was surrounded by farming, and the wind didn't blow. -The way Phoenix is during monsoon season.

Re: Shop Build (help appreciated!)

warmstrong— I want that boulder that landed on the highway in Colorado the other day. —Bill That was a biggun Bill! 2.3 million pounds they estimated. I saw a vid today, where CDOT, or maybe a contractor, had drilled it, and blasted it. Nice shot too! Good job! Not uncommon in Colorado, that’s for ...

Re: Help me Change a Kubota Quick Coupler

A note on that tightening thing......if you still have a leak.... It may work....but usually not. Pipe dope will set up after a short period of time. If you dope something up, and reassemble, and it still leaks....chances are, you missed a spot, or a bit of oil was still there, and you have some met...
