Strap wrench on the wrong way round!
Bob | 11/08/2010 20:03:48 |
51 forum posts 1 photos | Fig 5 Page 43 is labelled Removing a chuck, but the strap wrench is shown in the correct position for tightening the chuck.
I always find that jambing a block of wood between a chuck jaw and the rear shear of the lathe and then engaging back gear and pulling the belt in reverse (by hand) will loosen even the most stubbon chuck.
It would seem to me that there is something wrong if you need a strap wrench to put the chuck on.

I've had a few posts deleted before now and the powers that be don't like criticism so I kept quiet..

180 forum posts | When i received the latest MEW that cover picture was the first thing i noticed then I found it repeated inside the mag. Is it a joke I thought, surely not? Like you Roy I held back from commenting & I agree with Bob re "putting on" a chuck with a strap wrench or any other means than by hand.

Just a badly posed photo me thinks.

Thank you for reminding me of a word from youth, flolloped, I haven't heard it for years and it immediately brought a smile to my face
![]() I too noticed the error in the pictures on receipt of the mag and thought its going to a lot of effort to unscrew it that way

2356 forum posts 47 photos | Anytime I've had a stuck one a strap wrench as shown in photo would be absolutely useless regardless of the direction it was applied.
Generally you need a lot more hold than that.
In extreme cases I have put a 3/4 x 3/4 x 3 foot bar in the jaws with the power plug out and belts and gearbox engaged to lock the spindle. A sharp rap with a dead blow or copper or lead hammer usually will start the chuck moving.
Use of back gear is not advisable to lock the spindle for this procedure because under these extreme conditions teeth can be knocked out of the gears easily.
a toolmakers clamp across a belt between the pulleys will often lock the drive solid enough.
Play safe

180 forum posts | This is begining to sound like the long stand we used to send apprentices to get from stores. Happy days!!

Then, since there's a predominance of steam enthusiasts in ME, you will also remember being sent for a bucket of the stuff? And what about bedding blue on the doll’s eye magnifying while reading the vernier, and the suggestion to swap eyes to get a better reading? There appears to be no end to these jokes.
Anyway, it's fun to look back!

436 forum posts 5 photos | It is a nice strap wrench, I confess I have never seen one before. FWIW I use an old seat belt removed from my Brothers Vauxhall VX 490 in 1968 and 24" of 2" X 1". Also works on Briggs and Stratton flywheels. Frank |

![]() 4318 forum posts 291 photos 1 articles | I re-read the article that refers to the picture (not the caption) and it's headed 'fitting and removing chucks' so perhaps he was nipping it up tight? Neil |

2011 forum posts | I've revisited the strap-wrench photo, in the article he does say "tightening a chuck". BTW an old timing belt makes a good strap wrench. |
