Re: Best way to remove material?

I've got almost a full collection of the Model Engineer magazine from the very first in 1898 that predated the Model Engineer title up into the 1960s plus lots more in the 1980's - 2,000s. Jobs like that were almost always done by marking out, center punching them, drilling lines of holes that almos...

Re: Shoptask 1720

Emco made and still make very high quality machine tools. That compound without doing a hands on check looks dirt cheap for what it is and it's apparent condition. I'd guess even making one would get you well over 3/4s of the way to it's price for something few of us could build nearly as well. I'm ...

Re: Shoptask 1720

Well if you need a compound and a quick change tool post then deal with the problem of getting that compound first since sizing a QC tool post is done from the compounds top surface height to the lathes center line. As for finding something that would work for a compound? We'd need much more informa...

Re: My new mill

Just like ctwo I've learned all my rigging lessons the hard way as well and always wished the companys I've worked for would have put me through a proper rigging course. What they can't do in those courses is show you real world rigging failures that can and do happen right in front of you. Showing ...

Re: BIG Dro Problem

Always great when things work out as well as expected Ron. I bet those frames got done much quicker as well.

Re: My new mill

If it's worth doing then adding overkill and hydraulics just makes things easier. :-) Nice mill and that crane sure helped. It worked for you, and while I know real Bridgeports are designed to take it I'm not fully convinced the offshore mills are totally safe while lifting the whole machine from th...

Re: Jacobs keyless chuck loosens when starting mill

Glad some of that might help and I hope you post if that cleaning works or not. It could be useful information for someone else in the future. Also a review on any new chucks you end up buying. At one time if you wanted a good keyed or keyless it was safe to just pick up what Jacobs was making. Now ...

Re: Jacobs keyless chuck loosens when starting mill

Well Badog might have nailed the problem down better than I have if you've oiled it. If so then maybe a simple disassembly, cleaning and regreasing where it's required just might do it. You might take this as only information that was correct at the time I bought them or not since I've no idea just ...

Re: Wrench Bench

I'm trying to figure out if it's ironic or logical to use slugging wrenchs as beer holders. :-) Very cool and someone put a great deal of thought into that Glenn.

Re: Jacobs keyless chuck loosens when starting mill

I don't own one nor have had that problem. Still not enough information to help though. Exactly how old is that chuck. For example is it old enough to still be stamped Made in America? If so? It's my understanding only from reading the Practical Machinist forum that the current parts kits Jacob now ...

Re: Hand grinding tool bits

A Youtube poster with the name of James Kilroy proved that red heat on HSS by heating the tool with a O/A torch has no measurable effect on it. Many say that micro cracking isn't a problem with water cooling. However my hunch is there's something to it if the tool edge or tip does get hot enough bef...
