Follow on question...what makes a dividing head "Universal" v. "Semi-universal"? Is it the external drive input? I got a crusty old BS-2 with the external input similar to the one shown on the left above. I may be seeking some group advice on it shortly. Since I'm asking, I know that the...

@CWret Mark Presling did a video series on a rear mounted parting tool holder. I think he makes a good case that mounting the blade on the rear has a lot of benefits. The T-slots in your cross-slide would make it pretty simple to add such a system. In fact, you could also follow the...

Hah! As if they'd ever deliver on a Friday!! Craig

Asking $2,500 on Kijiji but the one at auction in Lindsay went for just under $1,500 all in. The column on these things is really massive. I wonder how difficult it is to crank the head up? (Down has to be pretty easy!) Craig (BTW, there is a rusty anvil shown in the Kijiji listing. How...

Travers has a nice 2-page pdf 'cheat sheet' for carbide turning inserts: https://solutions.travers.com/metalworking-machining/turning-insert-code-chart They ask for your name and email address to get access to the download but you can opt out of the emails at any time. Craig Thanks Craig -...

This is a bit beyond my pay grade, but AIUI, automatic reference counting in Objective-C and, more lately in Swift, is all about avoiding the problems related to garbage collection. Both those languages are, of course, most strongly associated with Apple. Craig

All the 618 parts were sold months ago, sorry. Could a moderator please close this thread? Craig Edit - done.

@kstrauss what lathe are you using? @gerritv You've got effectively the same lathe as me so I could be talked into following your footsteps, exactly. Precisely. Even blindly. If you can point me to a particular package of inserts and related insert tool holder for basic turning in mild...

Lee Valley Tools offers drill bushings. Do they have the size(s) you need? https://www.leevalley.com/en-ca/search#q=drill%20guide%20bushing&t=product-search-tab&sort=relevancy&layout=card&numberOfResults=25 Craig

Hi Ken: Just to offer an opposing experience...I find carbide inserts one of the most confusing subjects out there. A couple of time, I have spent considerable time reading and trying to decide what to purchase. Effectively, I've ended up with "analysis-paralysis" and never actually clicked...

I was out to visit yesterday and he does indeed have a user-made 'quick-change' toolpost. Two, in fact. You can see them in the picture with all the chucks and other loot. They are a super simple design where the dovetails squeeze against the tool holder via a single SHCS. There is a pin...

Awesome. With the accessories, it seems that you have some form of quick change tool post (2x)? BTW, why the electrical box on the side with the forward-reverse switch on the front? Craig

Re 1/4-24, etc. AIUI, before the Unified Thread Standards, there was a set of National standards in the USA. Both were based on the same 60 degree thread form and many of the National standards became Unified standards with no change. A notable exception was for coarse 1/2 inch fasteners. NC...

Is it time in this thread for...

Did you see @LenVW 's post? #11 Golden Triangle Specialty sounds like a propect. Another avenue to consider is ordering online. For example, I bought a couple of 'Protoboxes' from Online Metal a few years ago. At that time, I was using a cross-border shipping service in...
