    Hi Karl, Guys,

    It might be that the manufacturer has made an allowance for tool flex !

    From some of the videos that I've seen there seems to be an awful lot of lathes that flex when parting, or just turning for that matter.
    Best Regards:
    Baron J.

    I reckon Barron and Pippin take the prize on this one. Flexing would be the most logical reason to specify an above center setup.

    What edge on the insert do you set the height to, the centre or the sides?
    I use the centre to set the height.

    A parcel arrived today containing the parting off and threading tooling.
    Upon opening the three layers of bubble wrap, I found two well finished tools, two packs of shiny new inserts and a parting off blade. I had a couple of parting off jobs to do and so I let rip with the tool, I was only working with 50MM brass bar and 1'" shaft that I believe is probably 1020 material. I set the tool on center, having seated the carbide insert in the blade with a few good taps from a piece of pine. Upon offering the tool up to the 1020 bar stock which was machined to 14mm at that point, I was very impressed at how well the insert cut, certainly better than the carbide parting off tool at work and the tool cut until the material was down to under 1.5mm, whereupon the material snapped cleanly leaving the chuck side clean as the tool progressed to center. As expected, the brass cut easily and I noted a very good surface finish was left on both pieces and in fact the same was true when parting the 1020 material.
    The threading tool will have to wait for a little while to be used as I'm a bit snowed under with work at present, however I did note that the inserts are very nicely finished and the ground surfaces have a uniformly high polish on all edges.
    All in all, I am very satisfied at this point with both the tooling and the freight performance - dispatched Friday and arrived before 10 Am this morning for a freight cost of $20 is bang on in my book. Maybe I could have saved a few dollars, but I'll never really know as I'm not going to buy another set just to compare.

    For some reason I had in my mind that Boyar Tool was a US based company. Upon reading how quick you got it, I discovered they're not. I also discovered I've been on their website before, and wrote them off as a defunct entity, given the website shows as being last updated in 2005, and tells you absolutely nothing useful.

    Case in point - apparently he sells measuring instruments. But clicking on that simply gives a list of various types of metrology gear, which reads more like a dictionary entry rather than a stock listing due to being suspiciously comprehensive. On a more modern website, I'd fully expect to click on half those items, to be greeted with 'no results found'. None of the 'Top Brands' listed in a separate page appear to have anything to do with metrology, so I'm none the wiser as to what he may or may not be selling, and from who.

    Pray tell, is there some way to actually get some more useful idea of what specifically he sells (maybe one of those heavy paper based things you use to kill spiders for the missus?), or is it a case of emailing through a shopping list/playing phone tag and hoping he's actually got the things you want?

    Good to hear the quality stuff performs well.

    I had a 26mm x 2mm parting blade, holder & insert kit from H&F that worked fine - not knowing any better, I routinely power-fed the parting operation with no problems at all. However I eventually managed to break both ends, entirely by operator error, not tool fault.

    In my case a new blade and 10 inserts from H&F comes to $180 (on sale at the moment). But on the other hand, Banggood have the same spec - 26x2 blade and 10 inserts for $32.60 with good reviews. I'm currently using a HSS parting tool, and kind of enjoying having to learn how to sharpen and apply the right features, so can probably deal with the longer delivery time from China. And they offer more insert options than H&F.

    Not in my experience. Neither the website, an email nor phone call elicited the information I wanted. All I wanted to know was the price and brand of their knurling wheels and how much postage was. I got the price via email, postage from the phone call and never did find out what brand they were.

    I ended up piggy-backing on eskimo's order from Accu-Trak in the USA.

    Boyar's website is rubbish for sure and I honestly think it does him more harm than good. I am guessing that for a one man operation, it is probably not easy to run a business and keep a website updated. Probably time to put different systems in place as it doubtlessly gives a negative impression.
    It sounds like you had a really negative experience Jack620. I found emailing to be effectively useless and to be honest phone calls have worked well for me, although it does usually take until the following day to get a quote via email for more complex orders. I also suspect that his business is geared more towards supplying industrial clients that small timers.
    I would never have known Boyar existed if I hadn't been referred by Austral Machinery. It is easier by far to purchase from the likes of LPR Toolmakers, H&F, Ausee or Magpro, but I think, based on my experiences so far that you may get a little better quality product from the likes of Boyar.
    My 2 cents worth anyway.
