    Why do you need the first square layer? You can use four sides of the octagon to cut/index squares.

    The young man who produces the original, hopes his business will grow. He called me for feedback on his product. He is an American, lives in Wisconsin. If everybody makes one and he doesn’t sell any what happens to his dream? Buy one from him please. Google Lakeshore carbide They are selling them for him. (Yes I’m sure they are marking them up a little, but they are an American company as well.) In the end you will still die with money in your pocket anyway. We all know that. As always an excellent video by Pragmatic.

      37yearsofanything isenough While you may want to support the young inventor that is all well and good. But it appears lakeside carbide do not ship over seas . Selling on ebay would increase market .as for china copying? Well i am sure they will see it some where anyway like here on YT and other sites

      37yearsofanything isenough yes i meant Lakeshore not lake side as i wrote . The price is reasonable but lack 0f shipping to New Zealand (more so in these times ) would only leave one choice for me

    Lee why not just cut the corners all the way? Clamp in a V block and mill off the corners (for 4 sided cuts use every other of the flats)

    Hey Lee, just a quick note, its hard to know if the marks on the vise swivel are accurate. You are looking for parallel sides. It would have been just as easy, and maybe ... maybe more accurate to put a stop on your vise, remove the piece and turn it and snug it up to the stop. That way you are sure that you have parallel sides. you can be sure of the 45, the 90 from the 45, and the opposite corners.
    Good build though. I think I saw Randy using one. Good build.. When I saw his, I thought the same thing about building one.
    Those needles stick to everything. I setup a vac when doing that. Even on hot metal, I make sure there's no fire before I finish up

    This will be a good project for my new Wilton 11704 3-Axis vise...I look at the date of this video,,,was done when we here in TX had the Blizzard of 2021, and no power for 7 days.

    Lee, like yours, on my column mill the real estate is always a problem. Now that I own a 3 axis vise, my turn table just seats. My indexter only needs me to make time to finish, but check it out if you have time, and hope you will subscribe,,Bear in Tx

    Really an inspiring video. MrPete222, Tubalcain, recently showed the use of this. He used the name "Rose Index" giving me the idea to make one. Here we are. Compared to 4 and 6 sided collet chucks this device has a great advantage. I'm sure it will come clear in the next part of the video.
    Great footage, lots of work with camera angels and editing.

      Yep and I mentioned I’d make a 3D printed one which I did and the guy from rose index got all bent out of shape. I believe you can make anything as long as you don’t sell them?

      Yeah, the owner, Timm Rosenthal was just in an interview with Aaron Engineering (5/19/2022 on UA-cam) and he was fussing about people making sets for themselves, he said it was theft and disrespectful.
      Aaron made a 3D printed set for himself and done a video on it, then Mr. Rosenthal saw the video and contacted Aaron to raise sand about it so Aaron agreed to do an interview with him to promote his one and only product.
      Rosenthal says that his invention is his idea and his alone but people have been using very similar methods on round bar for decades if not centuries.
      Shoot, back in the 70s, I used to tack weld a large hex nut to the end of round bar to use for indexing in the milling machine, then knock the nut off when I was done, it was easier to use hex nuts since the round bars were always such different sizes. I'm sure that using a hex nut for indexing was nothing new or unique!!
      I have also used a small straight bar tacked to the end of a rod, then used precision angle blocks for indexing specific amounts like 45° or odd angles or whatever was needed, there are many ways to easily index stock when needed.
      Rosenthal never cracked a smile during the entire interview.
      I wouldn't even consider buying his product after watching his interview, what a stiff shirt!!
      And yes, anybody can make anything they want even if it's patented as long as they don't manufacture it and sell to the public.

    I've seen pictures of jigs like this, it's interesting to see how you approach the making of yours. And you're right, that angle plate went on the wall right away when I bought my first mill vise, only used it a couple times!

      In my phone conversation with Mr, Rosenthal I cautioned him against putting his index on eBay or Amazon. A lifelong friend of mine who sells at art shows, told me the Chinese will copy anything they see on those venues that they think will sell, and have it back here within the week! They watch it like a hawk. (I learned something) They are available from a company called Lakeshore Carbide. Google it. They are not cheap, but very well made accuracy wise.

      Hi
      As you will no doubt be able to see I have edited my comment as I think you misunderstood them. What I was trying to say was that using a rule (scale) to mark out the lines and a set of compasses is not very accurate. So if you use your jig to cut a hex / octagon then you should realign the cutter for each side if you require accuracy.

      @@chrisbaker3844 Thanks for stopping by Chris, but as I stated multiple times in this video, "the lengths of the sides do not have to be the same - the only thing that matters is that each side is at the correct angle to its adjacent sides." Heck, even the hole I put in the piece in the second part doesn't even have to be in the center. Stay tuned :-)
