Thread: A cord of Ash
11/10/2019 14:08:47

Hi All

for what it's worth a cord is a volume 4' x 4' x 8' or 128 ft3. I have seen reference to it in British books about coppicing.



Thread: Help with a boxford c
09/10/2019 18:39:19

Hi Ian

I forgot to say that I have used Fenner Powertwist segmented belting on both the Cs without any problems.

Hi Ian

Grandmothers and eggs etc., Boxford use two grub screws, one against the shaft, the other to lock the first. Are both out? I have two C's and have added power saddles to both, a worthwhile mod in my opinion.

hope this helps

Thread: At last - no more chattering when parting off!
07/10/2019 11:08:53

I thought it was camera shake at the beginning of the ''parting off'' then looked again and realised that the lathe was moving!

Thread: Hammer/Drift
01/10/2019 15:21:30


Is this what you mean? Was referred to in a thread started here by Capnahab on 5th July 2015. I used one once, I'd like to find one for myself, it was a great device.

Ah, another Viz reader!

Thread: Issue 286 - Bridgeport Article
30/09/2019 17:03:59


despite the lack of the annotated figure 4 in your article I was able to identify all the controls described in the text. Also I learned a lot about the capabilities and weaknesses of the machine. A very helpful article.



Thread: cutter slippage using ER series collets
27/09/2019 22:25:34


do youu use a ball bearing type closing nut? These allow application of the high torque required to close these collets with ease. I use them on my ER 32 & 40 gear, I assume they are available for ER 25.



Thread: How to repair old King Dick socket extension?
27/09/2019 22:19:00

I was given a half inch extension bar missing its retaining ball. I found a suitable ball and spring in the treasure chest. I then turned up a simple die with an annulus sized to contact the parent metal around the ball bearing and at the same time depressing the ball slightly. Hardened the die and then popped it and the bar into my hydraulic press, gave it a good squeeze and to my surprise it swaged the bar enough to retain the ball whilst retaining enough travel for the ball to do its job.

This must have cost more in time than it was worth but the idea was proven.

hope this helps.

Centimetres are an unusual unit used by maths teachers and dressmakers.

Radius is a mythical thing used by turners and mathematicians.

Real engineers use millimetres and diameter!

Thread: Shell Petrol Can Puzzle
25/09/2019 15:24:25

I wouldn't put the suspected leaded petrol in the car tank unless the car is designed to run on leaded. Google revealed the following:-

"The addition of even a small quantity of tetraethyl lead to your tank will contaminate your catalytic converter, and reduce or destroy its ability to minimize pollutants."


Keep it for the lawnmower.



Edit to remove ''unleaded''

Thread: Recommendation for Tool and Cutter Grinder

I'm a Luddite as well but i believe 0.35 mm is about 14 thou or 0.0138".

Sorry to be a pedant.


Thread: Stuck oil filter
12/09/2019 10:40:57

I have done the same as Jann, more than once. Don't get too close to the engine block with your screwdriver in case you hit the nipple that the filter screws onto. This method is not very pretty and a little messy but it works.



Thread: O rings.
11/09/2019 15:30:18

Hi if you Google Superseal, who publish a pdf of ring size charts you should be able to find the reference number for any O ring you need. You will certainly then find them on Ebay as suggested by Sandgrounder,

Thread: How to upset the neighbours!
09/09/2019 09:38:34

I'm green with envy! I ran an MGC GT from '82 to '86 but it wasn't quite like that one. Mine had a pair of 1.3/4 SU's not triple Weber DCOEs. Standard power was 145 BHP but I imagine this one produces a lot more.

MG made approximately 9000 of them between '67 and '69, I believe that half went to the USA. It was an attempt to follow the discontinued Austin-Healey 3000 but didn't quite manage to do so. One complaint was that the car was very front heavy.



Thread: Just for fun what’s this stuck in my tyre?

Can I claim my prize? Someone said it is a Hardinge HLV-H lathe?

Seriously, the gutters are littered with these cartridges around the Cardiff/Newport area. I see them lying there as I cycle in to work.

Is your Comet back in one piece now?

'Sparklet' CO2 cartridge? Blunt end of course!

for what it's worth the clamping mechanism is described by GHT in his book 'Dividing and graduating', page 59 in my copy. It is used to clamp the spindle of his Versatile Dividing Head.
