Re: Mr. Pete just started a series on the Unimat SL/DB on YouTube
¿ªÔÆÌåÓýI enjoyed watching that video.? I¡¯ve watched others of his before.? Always fun. ? Mr. Pete mentioned that he attached a foot switch to the Unimat.? I agree with him that reaching over the lathe for the switch is not a great idea, so I had also tried using a foot switch.? I use one on my air compressor and it¡¯s super.? ? I found that sometimes I¡¯d inadvertently tap the foot switch and turn on the lathe.? Fortunately it never happened when my hands were in the wrong place.? ?This happened often enough that I replaced the foot switch with a household paddle, or rocker switch that¡¯s mounted off to the side.? Works great and now I can safely tap my feet to the music. ? Scott ? From: [email protected] <[email protected]> On Behalf Of

Re: Mr. Pete just started a series on the Unimat SL/DB on YouTube
My friend, the late Lee Snover, operated a model train business for years.? He had an idea to make very small brass hex head screws(0.8mm x1mm hex, 4mm long and 1mm x1.4mm hex, 4mm long).? He could not find any shop here in the US that would do them at any sort of reasonable cost, so he had them manufactured in Japan.? The net result was that they sold very poorly and were an economic flop.? I still have some of his inventory of these.
So if you like to machine things or have some idea of a screw that you really need, then please enjoy your yourself.? But any very small screws are probably market-wise essentially worthless, which is very disappointing.? There is no need to say that we are all doing this for our enjoyment. |

I've always used the tailstock ram against the die when threading, even on a Unimat, never thought of using the toolpost to keep the die square. On a full sized lathe (when I wasn't screwcutting) I used to use the tailstock ram against the die with the end of the diestock handle running in an empty toolholder, select a low speed, start the chuck and off you go. Can't do that in a Unimat! Paul B.

Re: Convertidor
Good afternoon,
I bought them from "gadgetskingdom", reference 201177. This is on UK Ebay. The parts have a UPC reference of 746453424412. They work perfectly for me but I take no responsibility for anyone else being disappointed. Like me, "You takes your chance". I also worked on the principle that has already been mentioned in that there is very little room for error when running an M14 thread onto a tube with M12 inside it. It has to be reasonably accurate to even survive the machining process. regards, David? |

Three Optivisors in the house; one in the basement workshop, one in the basement spin-casting area, and one at my office desk for when I'm fiddling with stuff there.? Occasionally I walk around the house wearing one all day long ... Jeff

Re: Mr. Pete just started a series on the Unimat SL/DB on YouTube
Me thinks a bridgeport mill to make a milling table for a unimat isn't in my future... but I enjoyed watching it last night.? I have attended a few local options, and it isn't a price issue as much as an issue of how to move it.? I'll stick with bench top tools.? It is likely that a Bridgeport mill weighs more then me, so if it isn't on locking wheels, it isn't coming home to live with me.? I should move to Dallas, the Makerspace has one that you have to get certified to use but you would have access.
I am glad mine came with the unimat.?? I bought the Bedside Readers many years ago, and I am pretty sure, I have all three copies in print.? I had to wait for the price to bottom as they got really expensive when Practical Machinist puts it on the Christmas list.? Most print materials will come down in price, but it requires patience, absent of?a bottomless bank account. Tamra |

¿ªÔÆÌåÓýThe books by Tubal Cain in the UK are compilations of series of aricles printed in Model Engineer around about the 1980's. I remember at the time I found the articles very easy to understand and have some of the magazines of that era still. Mike
