Thread: Milling on a Lathe with a Vertical Slide
02/05/2021 12:08:43

I motorised my Myford VMD milling attachment and mounted it at the rear of the lathe bed as I got tired of fitting/removing it.

Yes an independent milling machine would be great - if you can allocate the space!

My album 'Myford VMD' has a few photos showing some details.

Thread: ML7 tight saddle
18/04/2021 20:41:12

Thanks for yours thoughts, as this was the first time I have experienced this in all the time I've owned it (35 years!) I don't think it can be a major problem, although at the next saddle service it could be considered.

Alan

Thanks for your thoughts. As I didn't find any obvious reason for the tightness I guess it could be a gib screw riding up in it's countersunk hole.

Just seems strange that in all these years it hasn't occured before? Anyway all back together and running great!

My early 50's Myford although getting a fair amount of use is generally cosseted. I use a bedway protective rubber sheet fitted to the left side of the saddle to keep the lathe ways clear of debris and always clean up and oil after every use.

Today while in use I noticed the saddle was tighter than normal to move so my simple 'clean up' ended up with a saddle removal expecting to find the culprit trapped somewhere. But no, nothing untoward at all?

After a good clean up I re assembled and oiled up resulting in the usual super smooth movement, strange but we'll worth doing.

I know people knock the old Myfords but while I agree they have their limitations, set up properly looked after they can do a good job!

Thread: Domestic water hammer
25/03/2021 12:44:25

Been looking at hammer arresters and to me they don't look big enough? Duncan's experiences? I think I was imagining something like the size (volume) of a small fire extinguisher. Tempted to make one.

Still have the bang and thump when operating cold taps although it is different - sounds more relaxed!

Alan

Interesting! The new valve is a direct replacement for the original and does not cause any thumps or bangs when operating.

Since draining down and refilling the effect is very much less than before and now only audible with tap 'turn offs'

Think I might investigate hammer arresters as we have had this effect in the past and it has been quite violent.

Had to replace a dripping (overnight) cold water tank ball valve. Turned off mains with a valve that's located immediately beneath the tank in our airing cupboard.

Work complete turned mains back on and we were getting a 'thump' when taps turned on and a 'bang' when turned off? Quite violent.

Why?!!

Turned mains off at incoming under sink, drained everything, all taps open, wc systems, all pipes containing mains.

All taps and valves off, turned mains back on and encouraged pipes to fill working its way up to loft - all ok now -

Don't understand how a valve 5 ft away from my original valve change could have caused this.

Anyone had similar?

Thread: Revolving centre, how to dismantle?
16/03/2021 19:26:06

Oilyrag, not got a name as such just 3 rings as you see with the words Trade and Mark either side. Obviously their logo but haven't been able to track it down. Still have the box which says made in Japan. Bought it probably 35+ years ago at a MEX.

Oldmart, you could well be right regarding the O ring although it's strange the grease has only recently started to emerge?

Alan

16/03/2021 10:04:57

Thanks for your thoughts.

The centre is running fine, no tight spots or free play and it is dead smooth (and accurate) it's only problem is it can now lose grease between it's moving and stationary parts. I guess an O ring has seen better days.

There is no obvious joint where it looks like it could be dismantled, hence my original question. If I can introduce grease 'through' the centre via the grease nipple on the end idea above I can at least replace the grease that is being lost.

Alan

15/03/2021 23:06:49

Thanks Oldmart, I quite like that idea, at least I can replace the grease that works it's way out.

Alan

Screwcut a threaded plug to fit the end of the centre, tapped M6 through the middle for a 'push out' screw. Gripped the tapered shank in a set of soft jaws and attempted to push it apart with the M6 bolt, by Jove it's tight.

Did it up as tight as I dared but stopped for fear of wrecking it, I got the impression it was assembled but not designed to be dismantled.

It runs fine at the moment so have decided to leave well alone until it shows signs of unhappiness! I am hoping that a ring of synthetic oil I applied around the accessible joint will run into where it's needed.

So obvious I didn't think of that! A scientific approach.

img_20210313_201422956.jpgimg_20210313_201259734.jpgHad this no 2 live centre for years, its compact accurate and runs smoothly but of late it has started to lose its grease. I am assuming an O ring has given up the ghost.

Trouble is I am unsure how it comes apart? The end cap will unscrew revealing an INA bearing but nothing else is obvious.

Any ideas?

Thread: Aldi Scheppach bandsaw
13/03/2021 21:15:51

I had a look on the saw and base and couldn't find any reference to China so scrutinized the box, nothing except on the bottom - Made in China! Almost as though it was trying to be hidden!

Anyway been using it again today and it's been doing a grand job - square and effortless on some 2 in by 1/2 in steel. I am aware the vice gets criticism but apart from the jaws being a distance from the blade it does a good job. I turned the rear jaw around so it's now about 1/8 from the blade and I will make a drop on blade for the moving jaw taking that closer to the blade, no big deal I thought.

All in all very pleased with it for £115 with 3 year warranty!

Ordered one of these a couple of weeks ago and I think my order got lost, didn't think I was going to get it at all as it then went out if stock!

It finally turned up and have done the first cuts with it today. Must admit to being quite impressed. Set the angle cut feature up to cut at 90 degree using a square and the results on a piece of inch square were good with a good clean cut using one of the two blades supplied (14tpi), it did it quite quietly and quickly.

Recommended, especially as it fits on my rack and can be pulled out for immediate use!

Thread: Junior hacksaw blades
08/03/2021 08:57:25

Just fitted a new (eclipse) blade the 'wrong' way round and in use I'm inclined to think less force was used on the pulling/stroke cut?

Seems alien but will continue with the trial.

Alan

06/03/2021 09:20:46

Perhaps I'm expecting too much? The blades I have are all old stock and are probably 30+ years old so pre date the cheap influx of 'pound shop' type product.

Having had a bit of a search and hoping to find something like the bimetal larger blades where we have a hss cutting edge but all I could find was hardened and tempered carbon steel so have gone for a pack of bahco ones and will see how they go!

Alan

05/03/2021 22:56:12

Thanks guys, I do try and take it steady when sawing although I didn't realise Bahco made saw blades, I've always been impressed with their spanners so will have a search for saw blades.

Alan

05/03/2021 21:17:20

For sawing most metals I use a 12 inch hacksaw fitted with usually a 24 you blade. I've cut loads with the current blade including lots of 2 inch bar - the blades been in the saw for months.

I also at times use a junior hacksaw fitted with an eclipse blade and am always disappointed at how long it lasts.

Can anybody recommend a make that will last better?

Alan

Thread: Help needed to lift bandsaw curse.
01/03/2021 10:11:16

Interesting post as I have only just ordered the bandsaw from Aldi which could be arriving today.

Viewing reports/reviews of this and similar I have basically assumed that the device will need some 'fettling' to allow it to produce what I'm after. These things are made down to a price but I think the engineer in us expects things to be right.

Nearly bought one a while back but resisted although since then I can't believe how much hack sawing I have been tackling!
