    I got a HSS parting blade holder with my lathe, when the single HSS blade broke I bought a 2mm cheap replacement as a quick fix. Still going on that quick fix, a real POS it is, but after some...

    It is a Rexvalter VF-118. Fortunately there is room for more meat, but I have kept to very close approximation of the original outer dimensions.

    It does seem cast iron in that size is difficult to...

    Sometimes I think PM should have it's own wikipedia so I can keep track of all the feuds, dramas and how they affect current user interactions. This Hobby Machinist stuff for instance, news to me.

    On this lathe the half nuts are likely to be in constant use, as they are used for longitudinal feed and threading, it does not work like the south bend on which it was modeled on, which IIRC use a...

    I model because I need blue prints to make the parts from. I can machine to the required tolerances despite the wear on the lathe (but it is annoying to work around all the time), the mill (deckel...

    I use a Foam extinguisher. It is rated AB and F and proof against 1000V at 1 meter distance. I think it's a good compromise compared to a powder one and the god awful mess it makes.

    I would in...

    Scrap yard mainly. Then I visit local shops and buy off cuts. I also use ebay and the net to buy certain things online when I need something specific.
  8. Cast iron and bronze lead screw nuts, a comparison of wear

    I am having apart my lathes cross slide and saddle for its regular yearly cleaning (I find it's needed, crud does get in there) and I removed a few parts so I could measure them and put them in CAD...

    I've never thought of the precision ground stones for use in scraping. And maybe I missed some videos but I can't remember anyone claiming to use them for that.

    Doesn't seem like a big deal in...

    2500 seems like a good price for an S13. I've seen them go for 2500-3500 in Sweden.

    I too should make one of those bibs. I don't have any vertical bellows so I've had the thought of making it longer, so it can give some protection to the box ways.

    Ultrasonic cleaning, black gunk on parts

    I cleaned some rusty old parts (old milling cutters) last night in a water & citric acid solution and I left them too long and they all had a black layer over them. IIRC it's magnetite and it needs...

    I am good for now I believe. I can always do it later if I feel it's required. I cannot do anything about the slots for now, the plan is I will make a new long t-nut when I have the equipment to make...

    I've scraped a couple of rounds and I got a real good contact pattern, basically all over and I decided to reassemble to test the deflection. I get zero deflection when I mount near the base on the...

    This is what the homemade stuff looks like. Use a dauber to put it on since I don't wanna use my breyer with anything but the blue stuff. Some mineral spirits on the dauber helps. Scraping a slight...

    I'll keep that in mind for next time, already got the tin ordered so I'll use it up first.

    I can't say I have a lot of experience, but I use Stuarts Micrometer blue and I think it works really well. I read a lot about canode but also about people having issues with it so I got scared of...

    Scraped both sides of the 1st part and am now working on the 2nd part and scraping a hollow on it, it's actually the opposite now. Took an intermission to finish the scraper though. Turns out it was...

    Yeah I'm using the base for that, and you're right about the leather as well.

    The scraper is a work in progress. I found that when I tightened it down it wasn't optimal, it leaned "backwards" so...

    Scraping some surfaces for a better fit. They belong to the swiveling table of my Deckel FP2 mill. Through years of misuse the parts mate very badly with each other and it results in a table that is...

    I have a motor I turned into a grinder with some cheap diamond plates (1000,1500 and 3000 grit). With the 3000 grit I can hone really fast. I use WD-40 to prevent carbide dust from rising.
