Ok, I am still doing the cleanup and set up of my new 8x14 and have two questions. 1) what procedures do you guys use to properly align the toothed belt? Do...
I think I figured out the wrench - it seems to be for the end of the stub shafts the change gears are on - they have the threads ground down on the ends into...
loosen the motor and tilt to get belt running in center of the large pulley,,,,,, check those guide washers on the small motor pulley the chines aren't to...
Happy New Year! I finished up my DC motor mod and thought I'd post a couple of photos (see Jeff's 9x30 Motor Mod) to show how the large 56C frame motor fits. I...
Can you give some more specific information about the motor that you used (model number), and also, information about what you did for the Ratiotrol controller...
I used a Pacific Scientific 90 volt, 1 hp TEFC motor that I found on ebay, PN SRF-3756-4996-84-5-56BC-CU. You can see details on Pac Sci motors here .....
Jeff, Nice conversion job! That motor will be more than adequate for any job that you will reasonably tackle with the 8x lathe. To those considering a similar...
Thanks Chris, One other thing to think about is the motor shaft diameter. The Pac Sci motors are like most in this range with a 5/8" shaft which is a loose fit...
Jeff, That's a very good point. That Boston Gear 1/4 horse TENV motor I am currently using came with a 1/2" shaft. I turned and bored a sleeve with a lip on...
OK a motor change why for what reason or did you burn the original motor out then I can see the point of going to a better motor providing the original...
Hi Charles, no cat among the pigeons here. This is just one of those mods that some of us do that makes our machinery more useful to us. If you find yourself...
halloo Chris I can understand about threading 125 is much to fast to come up to a shoulder that is a very good valid answer and wont argue about that one...
Speaking of variable speed...why don't one of you guys figure out how to take the dro out put on your lathe's cross feed and feed it back to the spindle motor...
hallo Reggie what digital speed read out lathe master dont have one ,,,,, I don't follow that train of thought the power feed is constant,,,, and the cross...
Sorry Charles, didn't mean to spoil your night. What I do now when I face a piece of stock in my lathe (I have a DC variable speed motor) with one hand I turn...
One way to do this is to make use of the tachometer input to your DC motor controller (assuming your controller has it). On the Ratiotrol, it has a tachometer...
I guess I will have to go to a "real" control system and motor. Probably aught to buy a real lathe also. My lathe (1940 Atlas severly modified including frame...
To be clear, even without the explicit tach feedback, a good DC controller will use armature voltage feedback to regulate speed loosely. The Ratiotrol spec...
Hi all. This is my first post here since becoming interested in the Lathemaster lathe. DC motor mods have been a subject of interest to me latley and I have...
Bernie, You can forgo the planetary gear if you will use a DC motor and a reasonable quality controller. The primary purpose of the planetary gear is to slow...
Thanks. would there be any advantage to having both? I am totally inexperienced at this stuff. Would there be any need to go say 25 rpm? Sent from my iPhone ...
Hi Bernie, I totally agree with Jeff here, the planetary gear is really a waste of effort with a good DC setup. The only way you might consider it is if you...
One of the objections that I hear to this kind of set up, with variable speed motors, is that the controllers seem to have a penchant for failure. Is this...
crikey reggie you started summit here all this grey matter sloshing about is bas for the digestion ... From: velocirex64 To: lathemaster@yahoogroups.com Sent:...
Motor controllers are big heat dissipators, as such they are subject to misuse and overheating which may be part of the perceived high failure rate. I would...
I think you are dead right there scr/fets can go at the drop of a hat,,,,, also there's not many people who rebuild these boards especially for those people...
hallo Reggie Charles returning not a problem I hit the sack and that was it I had a bit of thought what you where thinking about but too bulky for your set up ...
Hi Charles, I know what you mean about the South Bend! When I closed down the manufacturing part of Hitek Hardware, Inc. and became a "Consultant" I gave my...
I hear ya Charles. We may have to drag you kicking and screaming through the 00's as well to get you up to speed on this newfangled gear! :o) If your X3 board...
