Thread: What did you do Today 2018
27/03/2018 20:55:24
Posted by Andrew Johnston on 27/03/2018 13:30:09:

then I can flycut the chimney bases, perch brackets and ultimately the cylinder blocks for my traction engines. The outer diameter of the flycutter is exactly 8" and is concentric with the centre hole, which should help with the tool setting.


George -should have gone to Specsavers wink

Thread: Carborundum (silicon carbide) grinding wheel
26/03/2018 22:09:12

Get another grinder for green grit and mount them like this to save space. (Yes these 2 both have pink wheels, coarse and fine and the lower grinder is a 1400 rpm oldie) These are for woodturning tool sharpening on the front of the wheel.

I've got a pdf of the drawings from the Yahoo Group, plus the parts list. If I've still got your email I'll send it.

There is a file on the D-W Group which is called "Build Instructions", but it's only got the first 3 pages (2 of which are the parts list). The full instructions run to about 28 pages. The rest seem to have got lost.

Thread: Myford lathe headstock wick oiling ystem?

Now you've blown all the oil out of the system, I trust you refilled it and checked the level

Thread: Custom Myford cabinet ?
15/03/2018 09:18:41

Not a standard Myford factory cabinet (they only have one shelf and both ends are octagonal) but no doubt just as good.

So yes, it is a "custom" Myford style cabinet.

Thread: Argos sheds are they any good?
14/03/2018 09:30:07

These sheds are OK for storing garden tools, garden furniture, logs etc but not much else.

Feather edge boards will warp and leave gaps, the floors and roof are flimsy. The framing is the minimum needed to hold it together. Think of it as a big cupboard.

Much better is to go to a shed specialist where you can see sheds that have stood outside for a few years and assess the stability in person. Will cost more, but making the Argos shed into something decent would also cost, and you still end up with an Argos shed.

Thread: "Reforming" VFD Capacitors
13/03/2018 23:38:36

Standard practice for Siemens Micromaster VFDs was to reform the capacitors if they had not been used for specified periods, using a Variac.

The time taken at each step varied with the out of use time, if 1 year or less then no reforming, if 1 - 2 years then full power applied for 1 hour before use, 2 - 3 years then the Variac is used to apply : 25% for 30 mins, 50% for 30 mins, 75% for 30 mins, 100% for 30 mins. Total time 2 hours

If 3 years or more then the Variac is used for the same percentage times, but the intervals are 2 hours. Total time 8 hours.

This advice was contained early on in the user manual, under "Electrical Installation"

This doesn't apply to 400 volt Static Phase Converters, (Transwave type) which use a different capacitor.

Thread: ML7 Top slide T-nuts and screws
12/03/2018 23:12:50


OK, stood down!

12/03/2018 11:59:22


I've had a rootle through my small collection of Myford bits, and found one complete T-bolt and nut of this type. Message me your address in the flatlands and I'll send it. At least you'll have something to copy. Or you could hang it up in your workshop and see if it attracts the missing ones out of hiding !

You might try Mike Thomas at in case he has an odd one, but none advertised.

Happy to recommend Tuffsaws, a real user not just a shop.

I once saw a machine being offered for sale here described as "A drum and lade" !!

Off thread, sorry, but on our Freegle site someone was looking for "a chester draws".

Thread: Myford ML7 Manual Instructions
08/03/2018 16:17:51


If you can access a Super 7 Manual and look at the corresponding pages, the diagrams are much more easily understood, as they do away with this numbering and refer directly to "1st Stud, 2nd Stud, Leadscrew, Driver" etc which directly relates to the tables.

I would scan the page in, but we have recently been attacked by malevolent gremlins (probably the Russians) and the computer is gradually being put back to work, so no scanning just now. It is hugely frustrating!

If you are in the Myford Yahoo Group there is an old S7 manual in the files section, probably in the last file, which is actually a folder with several files in it.

Thread: Help for a simple wood turner in East Kent please
01/03/2018 17:18:55


Here's a pic of a sphere turning jig that was purchased several years ago at a woodworking show. Never used as woodturning ceased due to ill-health.

Might help with the design. Or someone might recognise it. It fits in place of the toolrest in the banjo.


Thread: Any other out of touch members ?

People wonder why youngsters are not joining the model engineering hobby.

They just have to read this thread to find out why!

Thread: Hobby related jokes

I saw an RAC Patrolman parked in his van. He was looking at his SatNav and sobbing uncontrollably.

I thought " he's heading for a breakdown"

You can get the magazines from this ebay shop **LINK**

But a bit pricey!

Thread: Thrust on Super 7 Counter Shaft
19/02/2018 23:15:26

If my memory serves, and with a look at the Super 7 manual –

If you look closely at the motorising assembly drawing in the manual you will see item 98 Part no A3329 “Abutment Washer” which fits between the clutch body and the Swing Head casting.

The bearing bush in the Swing head protrudes slightly from the casting, such that it lines up with the shoulder on the countershaft when this is inserted. The Abutment washer bears on the shoulder and the end of the bush on one side, and its other side bears on the centre of the Thrust bearing (item 99) in the rotating clutch body, so it is mostly hidden inside the centre boss of the clutch. This prevents the rotating clutch fouling the Swing head. The shoulder toward the left end of the countershaft can be clearly seen in the diagram.

The Abutment washer is 1” ext dia and 5/32” thick, so not a small item. Like most Myford bits it is chemically blackened, which helps it to hide from view!

Myford’s exploded diagrams are wonderfully informative, but their big drawback is that unlike a regular drawing you can’t see where each part belongs unless you’ve dismantled a perfect example.

So the simple answer to the original question is there should be a fat washer in there!

Thread: Bandsaw woes
19/02/2018 12:06:34

This looks similar to a Clarke CBS190. 190 refers to the throat size in mm. You can see a manual here **LINK**

If it looks like yours then you can try clarkeservice (or may be clarke-service) for spares.

Otherwise just search for "bandsaw wheel tyre"

Thread: Completing posts
16/02/2018 14:25:16

I have to say that recently I posted answers to two new member's questions, and when I got PMs saying thank you I was both astonished and delighted.

I used to get grumpy on another forum about people not thanking for not only advice but being GIVEN unobtainable spares etc, but have got over that now. All it did was stress me.
