Thread: Quick change tool post

Having to use shims is the main reason I want a adjustable toolpost. I'm sorted now .

Hi John, I don't have access to a mill plus my skill on that kind of level is not there .

My height of top slide to center of chuck is 19mm . This might seem a straight forward question to those in the know . What size of toolpost do i need , the palava over getting the right belt for the spindle was enough and i don't want to make the same mistake with this .

Swing over bed is ...160mm or 6.3 inches in old money

Height from top of the big T slot that the tool post sits is 19mm .75 in old money....

Looks good,but out of my price at the moment. Maybe write to Santa lol

I have a Fortis 12" swing lathe . Can someone recommend a tool post for under £100 . Toolpost just now is held on by a large T bolt .

Fortis up and running again... I noticed today when i switch on the the lathe the double strip light above the lathe goes out then turns back on after lathe is up and running . I use a good quality extension lead ,but since i've upgraded to a bigger motor i don't think it's up to the job anymore . I have some 3 core heavy duty cable and a weather proof double socket for outside the kitchen window and i plan boring through the wall and plugging in the weather proof plug so i don't have to bother unplugging the extension every time i'm finished ,would this be a better option ......

Thread: Motor pulley

I agree with Howard. The spindle speed makes no difference to the pitch of the thread. Many people rotate the lathe by hand for cutting short threads.

Les

Thanks Les

Thanks Howard , I have the old Fortis up and running now so i may try a few things . I may try cutting off the small pulley off the the original and bore out the larger one to 28 mm so i would have the correct gearing on the slow speed at least . (i think that's right ....isn't it lol) .

I now have the lathe running again , I went with a 95mm taperlock pulley,which i can slide back and forth when i change pulley speeds on the counter shaft drive pulley . I've setup the motor as a counter style mount with a spring for now attached to stop the motor bouncing and it works a treat .There isn't enough meat on the old pulley to bore it out and fit a keyway . My only concern now is ... will the gearing difference work now if I make a thread ?

Hi Sean, if you are stuck try one of the engineers stockist such as Eriks. Modern industrial pulleys are usually 'taperlock' type which has a separate bush with a variety of bore sizes for each pulley size, easy to fit as well.

Bill D.

Thanks Bill ,i've just gone and ordered from Simply Bearing the exact type of pulley you've described .

And then I'm going to try what Steve Pavey has suggested .

Hi,not done yet(liking the name ) I have considered the increase in power vs the old Fortis ,it'll be fine i thing this thing is built like a tank . I'm in the process of renewing all the bearings with better quality items . The only concern i have is that the new motor shaft is 28 mm so i wont be able to have the same gearing from the motor to the counter shaft . The size of the smaller pulley on the old motor wont allow (i think) it to fit the 28 mm shaft on the new motor . How critical will this be? . The OD of the stepped pulley on the old motor ... the larger one is 120 mm the smaller is only 70 mm on a 5/8th bore .

Sean

Measured the motor pulley last night the largest od is 120mm and the smaller is 70mm . There doesn't look to be enough material to bore it out and to 28mm cut a 8mm keyway. Looks like I'm going to struggle to keep the same gearing,this is going to be an issue isn't it ? .

Mark I couldn't tell you,the pulleys on the headstock are z .

The size of the pulley on the old motor is around 150 mm stepping down to half that .
22/11/2016 09:17:37
I'm kinda leaning towards boring out the old one but I'd have to do it at work on the Colchester,the keyway is the bit I'm not sure about doing,I've seen it being done but doing it my self is a different matter lol . I live in Nairn east of Inverness.

I'm trying to find a 2 step pulley withe a 28mm bore and 8mm keyway .... hens teeth come to mind ,either that or I'm not looking in the right places . My other option is to bore out the pulley on my old motor ,not sure my skill level is enough to do this .

Thread: Hoover motor died I think
20/11/2016 09:23:22
Disconnected cap ,motor needed help to start but ran fine . Connected cap back up motor ran nicely ,fitted it back onto lathe fired up the lathe ran fine for about 30sec then started smoking bad and tripped the electrics both motor and capacitor were very warm . Now I'm confused . New motor I think , the old one is 70yrs old so no shame to it .

Thread: motor/poles
19/11/2016 21:14:18

I'm looking to buy a new motor for my Fortis ,how many poles ,I believe higher number of poles equates to more torque . Seeing as the motor I have just now goes to 1425rpm I'm not sure what to get ? Anyone help out ?
