Hi Andrew; You may want to look at Minarik drives they sell a unit that will control the RPM of certain types of single phase motors. I did test one or their 3 phase units and it worked OK.

Hi all; Just wondering if any members have a Smart & Brown lathe say the older 1024 model. If you do does it have any large plus or minus points you could discuss? I just found out they existed and am interested in more detail.

Just wondering how popular these are with users in this group. I have a 1.5 HP drive on my 1 HP 745 Wells Index milling machine and really enjoy it, beats the heck out of changing belts all the time. It also let me increase the maximum RPM by 50% which is nice for carbide cutters or very small...
Well either very little interest in negative rake cutters in the group or I did a poor job of posing the question. How many in the group use negative rake carbide cutters in their mill? How about in the lathe, this I have not tried as yet. With only 1 HP on my 11" lathe it is not likely to work...
Hi All; Hoping to get a discussion started regarding the subject line. I have a set of negative rake milling cutters (3/4" shank 1" cutting diameter carbide insert type) I was hoping for improved surface finish and have had some encouraging results. They do behave a lot different than positive...
What is the best RPM to run for a .5" diameter mechanical edge finder. Does it matter what the material is, how about edge finder diameter or any other variables. This is assuming a vertical mill.

Just as a mater of interest my DRO runs on DOS 6.0. It is the YADRO system developed by Nick Mueller in Germany. If you are not familiar with the system it is a electronics kit that the user builds to interface economical scales to a dos pc. It looks like Nick is not doing any further software...
Dan thanks for the reply. My lathe is a 11" Standard Modern to use the taper attachment you remove the fastener for the crossfeed screw and use the compound to advace the cutter. My concern is a method that I can use to setup the taper attachment angle. In the past I would just sweep an object...
Hi all; I would appreciate some suggestions regarding the best method of setting up a taper attachment to achieve an accurate angle. This will be to bore a 5C collet closer bore in a pot chuck body that I have. It would be nice to not muck this one up. I have a 5" sine bar but no experience...
Hi Ron; Welcome to the group and a HAPPY NEW YEAR. I hope you have as much enjoyment from your machining adventures as I have had from mine.
I am originally from Sarnia but have lived near Sudbury for 40+ years. Once or twice a year I am in southern Ontario would like to drop in and see your...
I have been considering purchasing a set of Little Hogger 1" end mills. As the subject line indicates improved surface finish is at least one of my main objectives. Normally I machine a lot of 4140 and in the lathe I get what I consider a nice finish, but in the mill at present I use HS end...
Hi I am new here, retired old guy living in Canada.
I have had the castings to build a 1/3 scale Fairbanks Morse farm engine for about 10 years now. How to build the crankshaft has been one of many reasons for the delay, unless I get a move on I will run out of years to finish it.
So I am asking...
Hi All; Just hope that I am posting in the correct area. I have spent some time looking for a way to select different forums and just gave this a try.
I am retired (19 years now) and after retirement purchased some metal working equipment and went about learning the hard way. My goal is to...
