Thanks for the info on Zamak Bill.I stand corrected.I prefer my heavy cast iron DB200s.I am sure the Zamaks are perfectly fine for anything we do on the Unimat. I have a small collection of the cast

Hey Uni People. have a duplicate Early cast iron Unimat Fret/Sabre saw for sale. This is the round table model. Looking for $175US + shipping but note from Canada. Will get an estimate this week….

That is a neat display, it is very common to see completed models displayed, not so much the how it was done. The mini Shopsmith aspect of the Unimat is one of the most interesting aspects to me.

The article quoted talks of problems in the 1950s, but they have reappeared more recently. I bought some small fans to use around my desk on hot days. One of them stopped working - the other one is

I have one or two large ingots of ZA12. I’m not sure if I want to use it to cast the 4th axis harmonic drive or save it for the Gingery Shaper. Sent: May 24, 2024 9:44 PM To: [email protected]

Excellent find! Not what I was reading back a few years, but supports what I remembered...? That's not something I can always count on these days! Bill in OKC William R. Meyers, MSgt, USAF(Ret.)

Reading on the subject I did several years ago suggested that zinc pest is caused by adding lead to the pot metal to make it flow easier, and then exposure to humidity. Not a metallurgist, so can't

I found this:

Yes.? On the zinc pest, so folks can see what one incarnation looks like, this is from a Varney (notable model railroad manufacturer of yore) diesel switcher that was NOS and still originally

My father had a diesel engine model from the early 50's that incorporated the motors in the trucks (bogies?).? ?I found the engine in the mid 70's, but by then the "pest" had done its' work.? The

Or at least platinum. I've made a few of my own accessories due to those high costs. Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by:Good judgement comes from experience.

Some of the accessories are cast in gold, going by the eBay prices their sellers are asking. Just saying.

Mine under the chipped paint appears to be a zinc alloy. I have ZA12 ingots I bought for making the Gingery Shaper since Zinc behaves more like cast iron than aluminum for damping vibrations. In case

Right Bill, I think many if not most DB200s were alloy. It’s the MK1 and Mk2 versions I have which all are cast iron. Alan Alan Ehrlich Geneva, Switzerland Sent: Friday, May 24, 2024 5:20 PM To:

And in that pedantic vein, there are several different alloys called zamak with different proportions of allowing materials in them. Sitting on the shelf just out of reach are three ingots of ZAMAK 3.

Dick, I have a Unimat here that says it's a DB 200, but is light alloy just like my SL-1000. Both machines were used when I got them, so may be Frankenmats rather that as shipped. I've not made any
