    Any idea what metal I may have? (55HRC)

    Yeah it’s magnetic and it’s not stainless. It turned out that it is indeed 1045 however it is hardened to 55hrc. The seller didn’t realize it got that hard but it was the end piece and apparently the cut with a hot knife because he said the bandsaw would get chewed up by trying to cut the end...

    Any idea what metal I may have? (55HRC)

    I suppose I could try annealing it in the oven by 4140 specs and see what happens. Might get lucky and it works.

    Any idea what metal I may have? (55HRC)

    Here is a photo after quickly hitting the surface with a face mill. It is struggling to clean up. It’s definitely nothing I’m going to probably machine here unless I can find out what it is and possibly anneal it to make it machineable. I went through a $40 box of carbides already and that’s...

    Any idea what metal I may have? (55HRC)

    Here is the label that was displayed in the seller listing. Looks like ASTM a434 bc. I’m no expert but I thought 1045 was ASTM A108 ASTM A29 UNS G41400. I think he sent me 4140 which would make sense it’s a bear to machine and I wouldn’t have hoses it for this project. Am I missing something?

    Any idea what metal I may have? (55HRC)

    I purchased this block of round stock off eBay. Was told it is 1045. Realizing I need to slice in half and couldn’t fit in my band saw I figured I’d mill four flats. Wow, have to tell you that was something else it was extremely difficult to machine. I machine 1045 gear stock all the time and...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    Sorry guys I’ve been busy. I should’ve followed up earlier. Everything went well. After dialing the tailstock in we have a beautiful turning beast. She has been solid and I have been watching every few days to check for floor settling. It seems to have resolved flashing around all the edges and...

    Why Is Steel So Expensive?

    Yeah I voted for the man. He has a big mess. The entire trade regulations/agreements have gone so far to the advantage of everyone else. Hoping like intended this is a temporary ploy to even out the playing field. The current atmosphere has to change and yes I’d agree with your coal statement...

    Why Is Steel So Expensive?

    Old post thinking wow! $30 some for a small bar. Looking today with new tariffs and McMaster Carr among others and I’m seeing $135/ft pricing depending on grade up to $300/ft. Simply I want to make my own tool holders and it’s less expensive tonjust buy them. What a shame today’s world has...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    After test turning I am getting .013 (inches) taper over a 4” bar of 3/8 4140 after taking a .25mm cut. The smallest part of taper is at the lathe chuck. The tailstock is straight in line but I had initially suspected there is play in the tail stock quill despite the miles are low on a...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    Well I fastened all four corners to the floor and it’s impossible to get it exact between the cabinet and the floor issues. Front to back took priority. As soon as I’d level one side the other would change. This is the best I could get the twist out of it. The floor inconsistencies make it...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    The floor is problematic at this end (left side). Of course this is also where all the weight sits and gap needed to level it. Probably difficult to see in the photo but it’s uneven every direction each side of the cracks a 1/16 or more. Using angle front and rear lets me avoid having to contend...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    Photo of the modification I chose to use to widen the base and contour the floor taper. Also this makes it easier to attach with anchors and I can grind off the angle later if I don’t decide to scrap the stand when I replace it with a wider footprint. Setting the right side flat on the floor...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    Thank you for the reply and I agree that the floor is part of the issue at one It is in rough shape where it would normally need its main support. I dismantled the base and suspended the lathe taking measurements of the end cabinets and they are definitely out of square. Looks as though the...

    Leveling lathe on uneven floor before a CNC retrofit. Suggestions?

    Greetings everyone I’m new to post here and have a question for anyone who has experience or prior experience with the issue I am contending with. I’ve had this 13 x 37 lathe for around 6 months now and it’s been a good machine. I’ve done a few pre CNC upgrades but now I have all the components...
