It does seem to be readily available on the web in several locations; I presume this is the same document:


Although the squaddie¡¯s profile looks more reminiscent of 1944 than 1988.

I did a fair number of these courses once upon a time, and most are actually pretty good. May help anyone just starting out.?

The PDF manual I have resolution is too low to make out what this looks like. So I don't know if I have it or not.? Can someone provide a description or picture??

TIA

Suggestions to make a 4-jaw chuck?

 

Hi,?
Have you made a 4-jaw chuck for the Unimat? Are there plans that you would consider??
I would like to make such chuck. So far, Harold Hall' s plan at http://www.homews.co.uk/page211a.html seem to be the most doable one. Gingery's seems a bit fragile when scaled down to be Unimat 's size.?

Re: Recommendations for learning the basics

 

This has been a long thread. I'll give my two cents worth fully understanding it might not be worth that much. I like you acquired a Unimat with absolutely no knowledge of how to use it. It was long long ago, even before this group was started. It is a DB 200 Sl. black badge.? It came with two manuals and lots of stuff. One was a catalog & price list, the other was "Miniature Machining Techniques". These might as well have been written in Chinese.

I read and re-read those manuals trying to make some sense of how to use these tools. I did not know a right hand turning tool from a left hand one. So it was OJT. I acquired an inexpensive caliper and a 5/8 wood dowel. I set the machine up. using the manual as a guide and started to turn a short piece of that dowel. I slowly learned how to turn that dowel with the various turning tools. Plus using the caliper, I could see just how much a few thousands off the dowel was. This is how I learned. Did it take some time? You bet it did.

Also, like you and many others on this group, I am a model railroader. In fact, I use my Uni only for building models. I model in HO scale. I have made several steam locomotives including the drivers. Sounds difficult? Well it did take practice and lots of stuff in the scrap bin. In fact the first loco I made, I made out of hard wood. Much cheaper than brass. I did not attempt a brass model until I fully mastered making the parts out of hard wood. I have all the articles on how to make a steam loco from the various model magazines. Some go back the the late 30's.

Eventually you will acquire more tools. I work with the smaller drill bits, Nos. 77-80 and have the taps and dies for these small drill bits along with many others. I purchase my tools from American manufactures. I live in the states and yes there are still folks making tools here. The Chinese stuff, in my opinion, are worthless. Yes, It will cost more, but they are accurate.

Good luck to you.
Larry


Re: Recommendations for learning the basics

 

My recommendation on learning the basics.? Measurement is key, I was lucky enough to work in a place that not only had a skilled machine shop where I could watch how they did stuff, and as a technician we also had an NBS traceable standards lab, and frequently had to calibrate electronic and mechanical equipment.? ?With that being said I managed to obtain legally a 1x1x12 in standards bar that the lab retired.? ?I use that to practice with now that my skills have dulled since I have retired.? ?I would sit for hours on a microscope doing minute repairs to electronic boards and inspecting them.?

Jeff, I don't know about anyone else here in the US, but I'm a cheap bastrich, and even that is too much for my poor wallet for the forseeable future. Groceries have about doubled in price down here over the past few years. Gasoline likewise. Things like automobile work that I used to do for myself, I recently had to hire done. My poor old beat up 98 Chevy Pickup got brake work, suspension work, a front-end alignment, new shocks all around, and the gaskets replaced on the valve covers of the 5.7L engine, and it cost me $4076.76. IF I can pay it off in 100 days. Otherwise it will be $9000 with (HIGH!) interest. I'd just gotten $1200 in my savings account, and was preparing to put a couple of hundred bucks a month in there... NOPE! I've got half, approximately, paid off. Two more payments of $860 will clear it. If nothing else breaks. If I don't need surgery on my spine. Got the MRI's this past Sunday, waiting for the appoint to see a neurosurgeon. And hopefully he'll tell me that I don't really need surgery yet.?

I'm not the oldest old fart here, but I'm also not the youngest... And just hit age 69 a couple of weekends ago.?

Give it a bit, and someone who wants it might manage to shake his/her finances around to make it happen.?

It occurs to me that I'm working with steel balls ranging in size from 0.25 mm to 20 mm, and for each size I have a certificate giving the size error in microns (¦Ìm, not micro-inches), Often the error is zero. I should be grabbing a selection of them and saving then for times when I'm not sure about the accuracy of my measuring instruments. They would also have some potential for checking hole sizes. We also have them in 316 stainless and brass, but the errors tend to be greater.
