Thread: Chester Lathe timing belt
02/06/2017 17:03:17

My C1 lathe belt pulley will accept a Qualcast T 47169 belt (once it is cut down to 10mm wide!) and that is an "XL" size belt. If you google that code you should find similar belts listed. I ended up buying from fleabay/Hong Kong as 83 teeth is a non-standard size in the UK but 84 teeth are available.

In my case the Qualcast belt was a "short" and I have yet to modify the motor mount by extending the motor mounting slots so that it will fit.

The manual for the multi-mini is here: https://chestermachinetools.forumchitchat.com/post/manual-for-the-mini-multi-7111323

If the manual is correct the belt may be the same as the C1 lathe supplied by Arc Euro - http://www.arceurotrade.co.uk/Catalogue/Machine-Spares/C1-Lathe-Spares/C1-131-Timing-Belt although as far as I can tell this is an "XL" size belt of 5mm pitch.

Thread: A Filing Machine with motor drive
14/05/2017 14:51:39

It uses 4" files (with the tang cut off) - I can get these from Arc Euro in most shapes that I need. I'm using 2nd cut files that do seem to work - if a little slowly for roughing out. However if you cut out close to the line in the first place they are quick enough. The one shown in the machine is a 4" square file with its missing tang uppermost - ie it cuts on the downstroke. (It may not look it in the photos but the file is dead square to the table!)

I've just about finished making a "Harold Hall" filing machine. The drawings and article in MEW were followed pretty much to the letter. I have however motorised the device using a motor from a cheap drilling machine that has been lying around for a while. My first attempt at this used a 1" small pulley and 2.5" large pulley with a J section poly v belt (4 ribs) - this proved to be a bit "fast" and, whilst it did work there was quite a bit of vibration. I have now modded it to have a 3" large pulley and the whole thing is more sedate and controllable - it certainly shifts brass at quite a rate!

Thread: Lathe chuck removal
11/04/2017 20:51:25

Lock the headstock (maybe by engaging the backgear if the ML7 doesn't have a locking bolt). Put a piece of timber (hardwood for preference) in the chuck crossways. Use a piece a bit over 1" square and a couple of feet long, holding it near the end. Apply pressure to the timber to undo the chuck. If this doesn't work try hitting the timber with your hand. if still no joy then clout the timber with a hefty hammer!

Thread: John Wilding 8 day Weight Driven Wall Clock

The Pallet nibs are deliberately drawn and cut out very slightly oversize (as stated in the book). The pallet will not work to start with but as you refine the pallet action it is necessary to file away a tiny bit on each pallet nib in order to get them to work. You do this without changing the depthing.

For up to 10mm square. (usual disclaimer).  I think they have advertised in ME from time to time?

College engineering stock some square but unfortunately not as small as 1/16 http://www.collegeengineering.co.uk/product/imperial-13-long/ Might be worth a phone call to see if they know a supplier.

Super 7's were fitted with 3/4 HP motors originally. 1/2 HP may not really be enough.

Should take you to some pictures of my own power hacksaw. Made to a design published in ME some years ago. The original designer was a Mr R J Cochrane. The drawings are available from the ME plans service WE54.

It will cut 2"x 2" steel in about 25mins and 1.25" round steel in 5 mins.

The design says you need to weld the frame but mine is made without welding. The cost was under £50 as much of the steel channel and angle was from a friendly "offcuts bin" at a local steel fabricators.

Sorry not quite true..... MS will charge for new installations but not upgrades to the free version of Windows 10. If you don't upgrade for free and want to in the future you will have to pay.

Thread: Bending 4mm steel rod by 90 degrees

Leave the bit to be bent as long as possible to help - trying to bend a tiddly bit of steel rod is not easy!! Cut to length after bending.

Thread: Telescope mirror

Wash it in luke-warm soapy water - a few drops of washing up liquid in a bucket full of water will do. If necessary you could very gently wipe it with cotton wool whilst it is in the soapy water. Rinse with copious amounts of cold water, followed by a final rinse with distilled water (or water from a water filter if you don't have distilled). Prop the mirror on its side to drain and dry.

Thread: Clock Question #5
06/02/2016 17:37:39

If you have a dividing head 108 should be easy enough to do? If it is a 40:1 head then every 10 holes on a 27 hole plate will do it. If 60:1 then every 10 holes on an 18 hole plate. If 90:1 then 15 holes on an 18 hole.plate.

Thread: Power hacksaw
20/01/2010 20:14:53
I don't have relief on my saw and the blades seem to last forever!  There is a stop that you can set (carefully) so that the "drop" at the end of a cut is minimal.  i also built a retractable pin to hold the saw in the "up" position.
 
 
There were some articles by Duplex many years ago - I think these went with the Duplex machine.  There was also an article in MEW about some sort of damping device for a hacksaw.
 
If you download the ME and MEW indexes:
 
 
you should be able to search for the articles that you want. (Excel spreadsheets)
