  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

I know this question has probably already been answered here, but I searched and did not find it. Can anyone tell me the belt size for my Atlas 101-27430 lathe? I mean the motor-to-countershaft belt.

Found it.... the motor belt is size 4L350. I was not creative enough with my search.

OK. AFAIK, that's correct. And the spindle belt would be a 4L310.

Just to add closure to this thread... I got a Goodyear/Contitech 4L350 belt. It is about 2 inches shorter than the belt that I had been using, but it seems to fit the lathe better - the motor is now tilted up slightly - near the mid-range of the motor's belt-tension adjustment slot. And the belt fits the sheaves of the motor and counter-shaft pulleys well.

Just for information to find v-Belt: 3l is for 3/8'' wide pulley and 4l is for 1/2'' wide pulley. 350 is for belt 35'' circumference. Like for a pulley of 3/8 and cirumference of 26'' we obtain 3L260
