Re: Unimat SL - fret saw attachment
I抣l see your casting kit Jeff, and raise you a scrap pillar drill, a sewing machine motor and an old Black and Decker jigsaw attachment...
I have a (Chinese) pillar drill with a really sloppy quill that is destined to donate its motor to a Myfordboy power hacksaw as soon as my son抯 welding is up to it, so this might be on the radar instead. Unfortunately he has made it file on the upstroke, but it shouldn抰 be that hard to correct. Brian Gates Gillingham (Kent) UK Sent from Mail<> for Windows 10 From: jeffklender2003@...

Re: Unimat SL - fret saw attachment
Looking at some of these design, it occurred to me. If you are only doing small items. Then why not use the set of small Swiss "pattern" files. The use a small round shaft ~ 1/8". Some set are double ended and some are single. you could use a cheap wood router table and mount a jig/saber saw under it.听 A little homemade adapter and the saw would hold the Swiss style file. And most of these saw also tilt. Cheap, fast and mostly off the shelf parts.
Cheap Router/Jig saw table on Ebay. I see them a lot at garage/estate sale cheap and normally have the router with them selling for less then $20.00 Double ended set Single Check Ebay. Prices and Quality vary. But cheap to test and then buy good once you know what you need. 听Jeff |

Another thread question
听I recently picked up a small box of items labeled as " Machinist Lot". I have just started going through it and I have found two interesting HSS taps. 听One has this on it: SCSSNER .690-48 NS HSS PG2 the other has: GRAND听 11/16-24 NEF HSS GH3 ENGLAND The second is obviously a old National Extra Fine. The first one is a odd one, I have not seen a tap expressed as .690 before, and this is very close to the diameter of the 11/16, but of a much finer thread. And so the collection grows----- LOL 听Jeff |

Re: Unimat SL - fret saw attachment
Or how about an offset overarm that allows the handle to stay on the file Bill? Despite its apparent simplicity, I suspect any of us could spend the rest of our lives tinkering with a filing machine � one that dispenses with the slide by using Watt抯 linkage (like a beam engine) would be dangerously hypnotic. Then we could use his sun and planet instead of a crank to halve the speed...

Re: Unimat SL - fret saw attachment

Brian, Have you built one of the Hemingway kits?听 I guess it can all be machined on a Myford and within the home workshop.听 If so this maybe a nice route.听 I notice they are saying you can use it for filing also, but wont you need to use special files in the
device.
This looks like another project to make a project...

Re: new topic: extended x-axis way bars
Having drilled the first hole, you could bolt the rods onto the Unimat base, which will hold the rod in the right position for drilling the second one. You could also turn it over and spot through the base to get the spacing right. You just need a little care to avoid enlarging the hole in the base. I would spot through with a centre drill, preferably one that matches the hole in the base. Keith ---In UNIMAT@..., <roman@...> wrote : I am late to this question, but I made extended way bars for both axes of my Unimat in order to mount stepper motors on each axis. You can see pictures (and drawings) in my album (and in the Files
section). I used a regular drill press to drill the holes, I drilled and taped the first hole and then I used a long bolt in the hole to properly judge the orientation of the round bar in the vise while drilling the second hole. It is easier done than described, human eye is a precise tool. Roman |

Re: Unimat Lathe and Mill $375 Austin TX
Morning Unimat SL users,
I have contacted the owner of this unit and am making arrangement to pick it up. I own an older version that I use in my wooden toymaking and would like another unit. I am anxious to try the table saw feature. I have the indexing attachment on my current unit and it helps in stepping off spokes in wheels. I mainly use it for turning wheels for my toys. I hope to create more elaborate models in my retirement. Denis |
