Re: any advice for first time milling with dovetail cutter ?

Hello,For cutting an inside dovetail, one with the walls slanting in, about the only way to cut it is to cut a slot for the shaft first, then use the dovetail cutter. For an outside dovetail, with the walls slanting out. I milled to the outside dimensions first, then cut in very gradually. I'd use a rigid setup, and I'd use that end mill holder you made. For brass, well, brass is odd. Aluminum would be cheaper to work with, and more predictable. Just use some cutting fluid to keep the chips from gumming up the cutter and pressure welding. I used one in steel to make an adjustable tool holder. Since the inside slot was wider than the cutter, I got away with milling a slot and taking the whole thing gently. Harvey

Re: Introduction

I have found rock maple, a very hard, dense close grained wood, to machine very nicely with the high speeds available on the Unis. Soft woods tend to tear & gum up. at the moment, I'm cutting the barrel channel on a full sized rifle stock on my Clausing miller, using regular endmills, and even with the much slower speeds available on the larger machine, the wood cuts very well.

Re: any advice for first time milling with dovetail cutter ?

To cut dovetail slots, first use an ordinary endmill to cut most of the metal away. Then cut the DT one side at a time. On the Uni, this is best done in small increments. Brass is easier to cut, as a rule, than some Al alloys, especially the soft gummy stuff found in hardware stores. On Al, be sure to use a cutting fluid. WD-40 works, and there are lots of others.

Re: Unimat PC - any experiences or comments?
ransome michasiow
John,
The headstock and tailstock are threaded the same as the Unimat 3 so those accessories are the same. My opinion and I read it somewhere that this is more of a training lathe and should not be used for heavy cutting. I use the NON- CNC controlled lathe for light work Alum, Brass and it will work fine. WhenI used the lathe on steel I overworked the motor and now it will slow up when load applied. Looking for a motor. Have been trying to find out what is needed for the CNC version abut have been unable to hook up with anyone who actuals uses one and would share information. I am looking for a motor and any spare parts for either the UNIMAT PC or Unimat Basic lathe. Would buy a complete setup.

Re: Unimat PC - any experiences or comments?
Hi John
I have a Unimat PC that I have been using for to produce hobby items that I sell. It is a nice small lathe even if not used in PC mode. Parts are hard to get but they can be had. I purchased two more Unimat PC's on e-bay to have spare parts. The hard thing to find is the controller board that fits in a computer to run the lathe in CNC mode. Make sure the boars that comes with he lathe you are buying is working. The software is available but it works best in an older AT type computer. It dosn't work in a new computer. Lots of help is available on this board. Regards Bob BTW If you don't buy the lathe, let me know. I can always use more parts. Especially the controller board...

Re: Adjustable Tool Post for the Unimat SL-1000
J E TOBEY
Little Machine Shop sells the A2Z QCTP set I recommended. It has the toolholders as described. They do not have a model especially for the SL/DB series Unimat. That is why I called the owner of A2Z and got the suggestion to select the Atlas one like I already had. As I stated earlier, I had moved my A2Z set up from my Atlas to my SL, sockethead capscrew and all. I had 1/4- 20 T nuts for my UNI SL already, so it was a 45 second job to set it up on the cross-slide. I use 3/8 indexable tooling on my Atlas and on my UNI. They make for limited flex, even if extended a bit away from the support of the toolholder. I have 3 UNI's,a DB and two SL's. I would not hesitate to equip all three with the A2Z product. I have about 15 toolholders for the toolposts in several variations and keep them set up with 3/8 and 1/2 boring bars, and straight,right and left turning, and also facing tools. adjusting for centerline is a snap and they hold adjustment well. By the way, I am just a satisfied customer- no connection to A2Z. I did look at Mert's in the files, and have no doubt that it,too, would be accurate and effective.Regards,JET

Re: Adjustable Tool Post for the Unimat SL-1000

I would point out that the way one gets experience is to do the work. You can find material in the trash beside the road if you don't have the money to just go & buy it. That is where I got mine at first. I still have the boring bar holder I made from an axle stub that broke off a hay baler. Found it in the road when I was walking to school. Tools. He already has the lathe, but he does need a grinder & some toolbit blanks.

Now, it is necessary to point out that anything you have never done, & don't know how to do, is impossible of accomplishment. That is, until you take your courage in both hands, and try & do it. generally you find that not only can you do it, but you can easily do it again. Thus the impossible becomes mundane, and learning has taken place. The hard thing for most humans to realize is that nearly anything they can imagine, they can do.

I'm the proud owner of a Unimat Classic (as of this Christmas) andI think you will be in the minority. I used to have one of these (before it was called Classic), and it did at least get me started, and helped me re-learn what I learnt at school 25 years ago, when we used big Myfords and Harrisons! You will probably find its limits quite early, but it is possible to produce good stuff - it just takes longer. The basic techniques are all much the same though. Enjoy! -- Paul Boyd |
