Re: Machining 3d prints
@clankennedy2004?
I’m not sure what you are talking about. I don’t want a wooden compound rest for anything, but I do think that PLA+ will make a good one for this application. And, I’m not worried about microplastics. Too much worry about nonsense. I guess you comment was just a space filler. |
Re: Machining 3d prints
Sorry but i cant help but think we sometimes try to reinvent the wheel ! Block of wood. Drill some holes. Not sure but might have done the same job ! Also would have prevented the release of more microplastics into the environment, wormy or not ! :/ Just Sayin :/

Testing the draft message functionality
This is a test. Line one, go to draft…

This should be the way I always post because I always want to edit. happy I am…? And it saves images and all, test successful. now press send and you can no longer edit it.? |

Re: Unimat 3 Paint Color
I will try to tell you what can be done, but you must be able to spray, coarse tip airbrush or similar.
I called our True Value Hardware.? You get a Benjamin Moore DTM(direct to metal) alkyd oil-base paint, low luster or semi-gloss.? The paint comes in quarts if you want.? Take your Unimat 3 to the store.? They have hundreds of color chips, one of which will be very close to what you have on the lathe.? They will tint you one quart. Here are 4 pages of the white family: One of the brighter whites should do the job.? An additional benefit is that if you have a cooperative paint person, they can slightly change the tint if you bring it back. Now for automotive spray paint in cans:? it is available in various "white" tones to match cars that have been made.? However, they want to know your model and year.? Or the paint color code.? Maybe if you can find an auto paint store, they can match your lathe or come close to the color code.? But you have to find a store that will do this. |
Unimat 3 Paint Color
Does anyone know what color white was used on a Unimat 3 lathe?? I am trying to locate something that is close to original and available off the shelf. If I take a sample to a paint store it is possible they can scan it to mix up a custom batch but would rather prefer to purchase it already made (Spray Can or Pint, Quart). Searching the Forum and found reference to Zinc White. Most of that is sold in tubes for an Artist use as a base. The closest match will work fine for me as the unit is not going to be an authentic restoration.?I tried to post this on The Unimat 3 Forum two weeks ago and it is still waiting Moderator Approval.?

Re: If your Unimat SL/DB was misaligned with the headstock, how did you fix it?
Ha!? These were a set of weighted valves, made out of zinc, found at a Habitat for Humanity Restore store. I manually hack-sawed the large cuts, not too bad. A bit gummy for drilling. A test for lead came negative.? I would have melted and done casting instead, but it can't be done at my place.? On Thu, Mar 21, 2024, 10:14 AM McKee, Don {Quaker} <donmckee@...> wrote: Juan: |
Re: Self-made accessories for my Unimat MK4.
开云体育Hi Gang: My first accessories for my Unimat (1973) were: Live center: Two ball bearings and tapped M12x1 instead of spud for tailstock. And head stock spacer: It is 3/4" stock (19mm) instead of 20mm, but works fine. Aluminum, black anodized. A milling table, ground steel plate from a school project I scrapped: 1/4-20 tapped
holes, made 1/4-20 T-nuts to match Unimat cross slide. Somewhat later there was the column flange and steel base plate: The holes are all tapped 1/4"-20 since SHCS were available. Have fun! Carl. |
Re: Self-made accessories for my Unimat MK4.
Making your own accessories is a good way to fill in the gaps in our collection and a great way to improve our skills.
