Thread: Guided bus lane
27/10/2021 12:04:39

Missed the sign: there was a case not so long ago where a driver accused of disobeying a traffic sign successfully pleaded that at the particular location the plethora of signs amounted to information overload and it was not reasonable to demand compliance.

Drivers in Wales will appreciate the difficulty!

It would be worth buying /making some duckboards to keep your feet off the cold concrete floor.

Wear clogs and you will have "duckboards" with you wherever you go.

Apparently it comes from the Old french Vis, which comes from the latin Vitis, for vine.

Yes, and according to OED because of the spiral growth of the tendrils.

Thread: How to Mount Collet Closer Chucks ?
22/10/2021 16:02:47


Did you compare the drawing I posted with your hardware?

Noting that the knobs are different from drawing made me wonder if you have actual Myford items. Do they not include part no 1 (backplate) as shown on the drawing. I had assumed that this would screw on to the spindle in the usual way other chucks do.

I hope someone with hands-on experience can contribute.

Lovely "rough idea", by the way!

The entry for clamp in Salaman's Dictionary says "see cramp".

Traditionally, woodworkers used the latter term to distinguish clamp in the sense of a piece of timber fastened at right angles to the end of a table or other structure needing to be kept flat.

sparky mike:

Thank you for reminding me of these points; it doesn't sound as though you need instructions.

The photo seems to show two types of collet but the chucks both look like the Myford item: £250 in 1990 with collets at £18.75.

My price list says "It is of the backplate mounting type"

I believe the short link goes to the threaded hole in the headstock on the far side of the spindle.

PS p158 of Bradley's Manual gives more information; I will scan and post.

Not to mention the Cutty Sark fiasco at Greenwich!

I, too, should be interested in seeing the manual if there is such a thing.

I haven't used mine for some time but note just now that I have them set so that the cutting wheel rotates on its axle but the knurled wheel is fixed (the latter does, of course, rotate with the movement of the handle).

And see the news item about the farthing found under the Victory's mast.

PS Since she was built at Chatham I have long thought she should rest here.

I recently acquired a profile lathe tool with a 12mm diameter carbide insert - an instant single button tool, perhaps?

Thread: Watch out for scam emails from a forum member
14/10/2021 11:14:50

I assume that the member is an innocent victim of the scammer? He or she needs to change their email address.

Nothing so exotic as Kiev but I did once get an email purporting to be from a colleague who was "stranded in a hotel in Swansea and needed £££ to get their luggage released".

Thread: Super 7 questions
14/10/2021 11:08:10

That looks like a very nice machine.

I think that what you call the toggle link is the back gear key in Myford speak. Mine certainly has some rotational play but I can't say it's a problem in practice. An associated point is the importance of lubricating the spindle via the nipple in the pulley.

I believe that Myfords did use some metric fasteners in later production, an example being the big-headed cap screws securing the saddle to the apron.

Never mind drilling the holes, I don't know how they were laid out. Assuming the number is correct, how would you draw 352 equally spaced dots on a 6" diameter with a pen?


I think GHT proposed a way of working in his Workshop Techniques: as I recall, he suggested first calculating the distance between points, setting dividers to this and adjusting as necessary. A refinement where possible would be to divide the circumference into a convenient number of divisions so as to minimise cumulative errors.

Thread: What was the purpose of these tools

This was my first attempt at including images in a post and I have not got any words included.I added them first is that correct.

My way, FWIW, is to insert a carriage return where the image is to go and also where I intend to continue writing.

Thread: Chain Protection Sleeve

Such sleeves are used on recumbent cycles where there is a need to protect the chain.

ICE (Inspired Cycle Engineering) is a possibility.

The packaging says steel crankshaft but the chips and sparks say iron

Agreed. Founders sometimes use "semi-steel".

What was the process involving rotating a batch inside an enclosure? I thought it looked like some form of heat treatment.

Also, were the oilways completely drilled?

Thread: M6 thread locking/stiff screw
01/10/2021 10:30:03

Some cycle wheel builders use a product on the spoke threads that both lubricates to facilitate tensioning and then secures the nipple against rotation once the wheel has been finished. Apparently, linseed oil will do this but there is a proprietary product called SpokePrep.
