I'll come back and answer the other questions later i have to take the misses shoping and get my dog out a walk.

Thanks guys, you have gave me a few things to think about here!

Here is the lathe im trying to get working correctly I hope you get the image its the first time uploading a picture

I have to go out thismorning but when i get back i'm going to have a good look with all your suggestions in mind and see if i can get this running without burning this motor out! I will try to get a video clip for youtube organised to let you see what i'm trying to explain a bit easier. Thats if its ok to post a link through here?

Thanks everyone for assisting me!

Hi Eric

The saddle lock it fine i have used this before so i know what your talking about, its slack so its not that.

I have tried taking the belts off so it not under any load and its fine i only had it running 5 minutes or less though.

There not any play that i noticed but even without the belt on the main spindle its still stiff to turn i thought this would be about right with a brand new lathe, its had no more than 1 hour run time i think and i only purchased it so i havent used it any longer than 10 minutes.

I don't have the gearbox but i checked the gears and they seem fine there is a little play in them which is ok.

The lead screw has never been used on this machine until i used it yesterday so it shouldnt be binding, i also greased all grease nipples and oiled the ports.

Everything is stiff on this lathe, i had to loosen the two screws slightly in order to even move the half nut locking lever!

Yes its single phase and i can hear the switch on downrun,

I think the switch is fine it seems to work perfect and is as new as well,

I'll have a wee look and see what i can find, if i could have a look at another similar lathe i could feel the tension on this to see the difference but i dont know anyone close who has one unfortunatelly.

Thanks

Hi Les

The lathe has been lying for 30 years unused more or less, its not run in at all. the belt is not slipping and the pulley its secured by the key perfect, it turns by hand easily without any belts attached and it spins fine when switched on. Under load the shaft coming out the motor goes really hot and heats the aluminium pulley so hot you cant touch it without burning your fingers. The lead screw (right hand side) has a hand turning pulley that you can turn the lead screw with by hand, now this is quite hard to turn ingaged or dissingaged without the two half nuts on the threads. If i turn the chuck by hand there is some resistance there as well and it becomes even more resistant with the belts on, my first thought was that the belt that goes from the motor to the pulley was too tight and i lifted the motor and tightened the nut but the belt started slipping so i put that back to the way it was. there seems to be a good force for the motor to spin the spindle with the chuck on the end, there is no tight spots that i can feel if i take it full circle but there is a constant force all the way round. Trying to explain this is hard for me because i'm kinda new to the terminology and such. All the gears have slight play in them and are fine there not obstructing anything from spinning. I'm going to have another wee look at it today to see if i can get things spinning easier without straining the motor every time i switch it on. If i fix it i'll let you guys know what the problem was, if not i'll probably have a couple of questions to ask you guys. I really appreciate all the help you guys are giving me thanks!

Hi guys

I just purchased a more or less brand new and very very little used myford super 7 lathe. Everything on it is tight and smooth, i put a bit of alluminium in the chuck and engaged the lead screw for automatic feed, within 4 minutes the motor shaft and aluminium pulley went really really hot, the reason i noticed was that the chuck slowed down even though i was taking a really light cut with a sharp tool. When i turn the lead screw by hand it feels quite tight from the tail stock side. Any ideas would be really helpful and much apprecciated.

thanks
