Just downloaded MEW 315 on PocketMags and noticed there is no Page 56, it is a duplicate Page 53 including the page number.

Is this error in the print edition or just the digital edition? Is the problem page part of an article or advertising?

2 years ago I purchased a Fein -Slugger 355mm carbide saw. great fro cutting rhs, have cut up to 125mm. I have not tried it on round bar. It requires a different blade for aluminium. It is fast and accurate. They run at 1300rpm. Evolution list a chop saw at a similar speed.

The bush dimensions are in the original units, both bushes are the same outside diameter and bore. In Australia I could only find Oilit bushes that were available were too long and expensive, but no long enough to get 2 bushes out of the one length.

OD 1.1/8"
ID 7/8"
Length short is 3/4" Long 1.25"

I have a pair of new oilit bushes for the S7 in the shed as well as the thrust bearing. They are the last bearings I need to replace, just no time.

Will measure them in the morning. I bought them from Myfords because to purchase locally I needed to purchase 2 longer lengths of oilit which was going to cost almost the same as purchasing from Myfords.

I converted an old 6" grinder, needed to polish brass handles. Have not had any issues of the grinder stalling but if you are not careful the item being polished will go flying. The grinder is a 30 y.o. Ryobi,

You should find the top of the front shear and under the back of the rear shear. The forces of turning push the carriage down on the front shear and pull it up on the rear. Measure the thickness of the front shear along the front edge of the front shear. Maximum wear will be 4 to 6" from the headstock.

Your lathe appears to be suffering a common problem with old lathes. Most of the wear in the lathes occur close to the head stock. If you measure the thickness of the shears you will find the front shear has more wear than the back.

The best way it to put the bed upside down on a surface plate, but this is not usually practical. A camelback can be used , if you can find one the length of the bed. I found a 900mm straight edge and with feeler gauges could determine the wear, worst spot was about 0.010". Wear is on the top of the bed.

If you look around you may find a shop with a suitable surface grinder. It needs to be able to grind the full lend of the bed, travel needs to be longer than the bed including the head stock. I ground the bed on my 1958 Super 7 this way and it solved a lot of issues. Also did the wide bed conversion at the same time.

I purchased a new laptop 2 weeks ago, motherboard failure. It came with Win10. During the setup I was prompted to upgrade, all worked fine.

Have had more issues with Debian. old Debian 10 image would not boot. Issue was new hardware, had to install Debian 11 and upgrade the kernel to 5.14. All good but my old Win 10 image will not boot.

It is a US thread form 60 degree. Stanley were notorious for using proprietry thread forms.

Do you know the age of the plane? Is it US or UK manufacture.

I have a No 78 plane at home but am away for a couple of days. Also have a No45 plane with one screw missing, the hole was also stripped.Found a screw 1/4-24. Standard size, fitted a helicoil, new screw was loose, but others the same size fittted.

Will check my 78 plane when I am home.

I remember reading a number of years ago that Myford changed at least some of the 1/4" bsf cap screws to M6 due to the old Super 7's used 2 sizes of heads, large and small. The large head 1/4" Cap screws became unobtainable and the M6 Cap screw is between the 2 bsf head sizes. The large head we used to attach the carriage to the apron.

I would assume that Myford stopped all 1/4" bsf at that time but not sure when this occured. Check the manual if you have one, else get one.

Peter

I have a Stanley No45 plane. It definitely uses 1/4-28 for some of the threads as I had 1 thumb screw missing and the thread was stripped, Found a screw online and used a 1/4-28 Helicoil to repair the thread. There is also a smaller size used but I never checked the actual thread.

For network backups, you could purchase a NAS (Network Attached Storage). Otherwise backup to a disk attached to another pc, I use a Raspberry Pi with a couple of disks attached.

As Roy said, use a chisel to lever it out. You could clean the key with a file. The better way is to get a piece of key steel of the correct width and height, available in both metric and imperial. cut to length and finish with a file to fit. teh keyway.

You can also sometimes find a pre-made, but key steel never goes astray and lengths as relatively cheap.

303 Stainless is free machining version of 304. 304 is great for cryogenics, BOC used to make its cryogenic plants with 304 SS.

316 is better for Salt water corrosion, 321 for heat.

The early pulleys were aluminium alloy, current ones are cast iron. Not sure where they changed.

If you are not desperate, keep looking. I ran one for years with a piece missing out of the side of the pulley, alloy. Bought a replacement that is iron, but kept the old in the case I ever purchase a 3 phase motor which would be metric and require the pulley to be bored.

RDG periodically have stock. I you contact them they will let you know when they are expecting more.

I have one the same as yours, purchased mid 90's, missing the lever mechanism. Has been sitting in pieces for 20 years due to moving house several times and family issues.

On the list to reassemble over the next year.

Peter

In which case Pocket Mags would be better to admit the issue is theirs rather than blaming the publishers.

Peter:

Just look for Ring Open End spanners from a good brand. A set comprising 2BA and 1/4"BS to 7/16"BS.

The largest 2 Nuts are the Lead Screw Hand wheel nut and the Tail stock nut.

I would recommend the free VMware client. Install is easy, available for most OS's.

Just install DOS in it, once working make a backup and it is easy if you have issues.
