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: 骋搁础狈顿听 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 听闯别蹿蹿 |

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...

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 |

Re: Unimat box finish
I purchased my alloy Unimat SL new in 1968, and it came with a "mahogany" stained box.听 I still have it, and given the condition, I suspect it was a "semi-gloss" varnish stain, as it hasn't absorbed oil from 听years of use. I recently acquired a NOS Unimat SL, as my half-century old original was wearing out.听 It too has the same box finish which I believe is a varnish stain. |

Re: Unimat SL - fret saw attachment
开云体育Hello Steve: One bonus of the Unimat, is you can change the speed. I use my Unimat table saw to cut plastic building walls. My Harbor Freight saw spins so fast it melts the plastic, while at low RPM the Unimat does great. This would also be a plus cutting metal since you don't burn up the blade. Carl.

Re: Unimat SL - fret saw attachment
开云体育Fret saw or jig saw?听 I have the jigsaw attachment but have had limited use out of it - the blade wanders a lot.听 However I can mount a powerdrill type jigsaw blade in it, much more rigid, and use it as a sabre saw reasonably handily.听 However it's still only of use for rough cuts.听 I could probably improve my technique, but since it is usually disassembled, it's usually quicker or more accurate to cut by hand.听 No addiitional problem with 3mm brass sheet, except that the thinner the metal, the more twists and distortion will occur, bringing us back to hand cutting - fretsaw, piercing saw aka jeweller's saw etc.听 I don't have any more advanced tools than that anyway. You probably know all about the optimum teeth count for the thickness of metal, and lubrication etc.听 That is the other point - the lack of supplies of alternative and replacement blades. regardsMehmood

Unimat SL - fret saw attachment
Hi all,
I'm after a fret saw to allow me to cut some cl貌ck wheels. The material is brass sheet up to 3mm thick. I was just wondering would the SL fret saw attachment be up to the job? I can get one for circa 拢150.00 but I'm not sure how much a stand alone small fret saw would be... Steve |
