|Thread: Clarkson Autolock Mystery Tool|
Good Morning Gents,
Hope you are all well and keeping busy!
Sorry to change the topic here, but you are all chatting about Clarkson fittings, and I wondered if any of you could assist me here. This is a photo (I just took from my PC screen as it had to be Jpeg!) of a Beaver Mill, which I have, with a drill chuck. which I assume is the standard Clarkson 30 Int taper. I usually use the Myford drill chuck, set into a Clarkson 2 MT fitting, but this then becomes quite long and limits the size of the drill I can use.
My question is, are these drill chucks available/obtainable anywhere? Obviously I'd like to get hold of one.
Thanks for reading this and apologies again for butting in here.
|Thread: Brook Cub 1/2 hp Motor - Capacitor or not?|
My camera batteries failed just as I was going to take a pic of the motor. I've been able to swing the mill head around and there is what I assume is the capacitor on the outside - about 3 inches long by 1.5 inches diameter, sealed at base with what looks like pitch. The motor runs OK, but when I've run it for a few minutes, like this morning, it takes several minutes for the power to be restored. I assume now that the 'click' I hear is in fact the centrifugal switch. I don't think it's something that I can actually tackle, so I'll look around for someone that knows what they're doing, LOL! Even if I remove said motor, and remove the base plate I assume there's not much I could do at this stage to find the fault. Electronics are not my specialist subject I'm afraid.
I have removed the switch (as we speak!) and there's a lot of pitting, which I will try to clean up, possibly in the lathe. There are 4 wires from the Dewhurst to the motor. As you look at it from the top left:Brown, next: Black, next: Blue (bottom peg not used). Then one Black to the 2nd peg on the right.
Just about to follow the Youtube video - Beachcomber Bob. Looked at it before, now I'll try to follow it, LOL!
Can't do anything more right now until I get it all re-assembled. Thanks for your response. I'll be back asp!
Sorry to resurrect this post, but I am trying to find what might be the fault with my CUB motor, which appears to be the same as the one you are all describing. Not really able to access the plate, but I can read 'Cont' Rating Speed 1420, and possibly .5 HP, but too difficult to read. However...
My problem is that my old Beaver milling machine has this motor, controlled by a Dewhurst on/off switch (OK I know about the feelings of this switch, but that's not the issue her I hope). When I switch the Dewhurst to forward and carry out what I want to do ( usually just drilling a series of holes), switch off and when I want to start again all I get is a humming noise. I have to turn the Dewhurst switch to off, and usually have to wait for a minute or 2 until there's a 'click' and the Dewhurst will switch on again. I think the 'click' is from to motor, but, as I said, it's too difficult to access where it is.
Any thoughts or advice would be greatly received. thanks in advance.
|Thread: Myford Super7|
Thank you Norman,
I've read about the link belts, but as I have the Headstock spindle partially withdrawn now I have just ordered both belts from Lathe Spares.
Thanks for all the replies so far.
Probably the best bet, buy both replacement belts. Thanks for the link.
Well, yes it is a 5 and not an 8. I checked it again after I saw the serial numbers with 8 for the reason you suggest! As my S7 has cup oilers I assumed it was not a very early model.
What has prompted me to ask about the numbers is that I need a new headstock drive belt, having removed both spindles. In his Myford Manual, Ian Bradley states on page 10 that the drive belt should be 23 inch inside length. On another Forum I found 33.5 inches quoted, which I bought, and of course is totally wrong. The existing belt is about 28.5 inches (and this has no doubt stretched over the years (30 in my ownership). And I've been told by an 'auction site' supplier that the correct belt is an 'A' 29.5 belt. I'm tempted to purchase a 28.5 belt because, otherwise, the motor-to-countershaft belt will be too small!
Any thoughts please!
Sorry to re-open this topic but I am a little confused over the Serial Number of my own Super 7 Lathe. The number is stamped at the tailstock end, like most others, and it is SK 52518, which seems to be much earlier than those on this Forum beginning with an 8! It's the standard Super 7, in grey with a fitted gearbox.
Can anyone explain this very low number please? Thanks. Geoff
