Re: Drilling holes in rocks - Help

LOL, unfortunately I do Bill. :-) There were a few muskeg swamps up at Kemess Mines. Even the moose wouldn't try crossing that for 6-7 months of the year. I learned real quick to test the ground with a hoe bucket first before walking the machine anywhere when I got off the roads. Solid even dry look...

Re: Drilling holes in rocks - Help

Proper terminology between locations and country's can vary a lot Bill. When I was up in Ft. St John almost all of the native sub soils was scraped in or ground up by ice age glaciers. All of it has a high clay content so it's a massive problem any time it rains for more than 10 minutes. Get off a b...

Re: Disassembly of EMCO Compact 5 Milling Head

If I remember correctly on mine the pulley gets removed and I seem to recall there was snap ring holding the top bearing in place. Either way it's a simple assembly and should be obvious once you get into it. The screw/nut holding the pulley on was I think a left hand thread? It's been a real long t...

Re: Drilling holes in rocks - Help

Really tough work and a filthy, wet & noisy job as well Bill. Anyone who's done that job has my respect.I've drilled exactly two vertical 55' x 10 3/4" blast holes about 35 years ago. Way cleaner, easier and quieter than those air powered jack legs, but it was still enough to decide to stay away fro...

Re: Drilling holes in rocks - Help

Well then that TOH video should help. They neglected to point out that most rock has a grain structure a bit like wood. So it will break a lot easier in one direction than another if you can read the grain. And good thing your not in a hurry, even using 1,000 lb and up to multi ton rocks to build a ...

Re: Drilling holes in rocks - Help

Good to hear your healing Bill. Split rocks? Ok since no one else has asked then how big, how hard and just how many? The drilled holes with the feathers and wedges will work up to some really big rock, but even with a hammer drill it's fairly slow going. It it's big enough and you've got a number t...

Re: installing quil on mill drill

Since the machine was originally complete and a safe guess it was in working condition then the hole was correct. I'd urge you to think, ask whatever questions are needed, and proceed very cautiously. Once metal is removed it can be 10 times the work to put it back on if you start making mistakes.

Re: Creating a GROOVE inside a very small TUBE (on the lathe)...

Already hardened metal items will obviously work, most of it will be some type of high carbon steel with unknown quality's. And yes high carbon steel was and still is used today and it was the only tool steel available for multiple century's. But it's now mostly used in home shops to come up with cu...

Re: Internal tapered bore

Depends on how your lathe is equipped for that best method. Ideally as Whateg0 said a proper taper turning attachment would be about the best method without the correct chambering reamer. Most TT attachments seem to have about + - 10 degrees per side for angle setting, and while I don't know the tap...

Re: grinding carbide inserts

The slow speed diamond grinders Glenndo makes have accessories to re-grind inserts. https://accu-finish.com/ Other than the already honed and usually aluminum specific inserts most other inserts that I know of have the cutting edge in the same condition as the sintering and coating process leaves th...

Re: installing quil on mill drill

If I'm reading your description properly your talking about the shaft that has the pinion gear on it right? With that shaft bent it try's to force the pinion teeth deeper into the rack teeth on the back side of the quill. Since the already low clearance between those two parts wont allow that to hap...

Re: Amazing machine work

To my ears I like the Merlin better than the round engines, maybe it's the super charger that helps the sound. Either way I can only afford to listen to them though. :-)
