Thread: kerry super 8 bench drill
26/05/2019 09:47:31

Hi John,

I have a Mk1 but I have never had the guts to remove the spring cover. The old adage "don't fix what ain't broke" and the thought of that spring laying in wait like a coiled viper put me off. If you have any details of how to adjust it I don't mind taking it apart, it is well over due for a spring clean, sorry I could just not resit that one.

Thread: Restoring a Myford ML1
25/05/2019 16:37:56

Hi Peter,

I agree with Stew, that is not a restore for the faint of heart. I have my late fathers ML2. The chuck end cap broke just like that. He cut the whole top section of the bearing housing off and hand made a brass 1/2 cap. Sounds great till you consider there is no way to adjust the spindle to bed alignment. I still have not tested the alignment on Dad's lathe.

The tailstock is meant to have two halves like that. My one has 3 screws in each half. Not sure if it is original. On my Drummond B, the segments have over lapping halving joints and only two screws. So each half holds the other half in place.

I would advise getting another lathe and keeping that as a one day project.

Thread: Harrison wiring
25/05/2019 08:05:00

Ha, great minds, Gray found the same diagram while I was typing my reply

25/05/2019 08:02:49

I had a quick google, it looks like some Harrison 300 lathe uses a 110V transformer to power all the switch gear. If so not connecting the transformer means it will never run.

**LINK**

If this is the same lathe as yours, the transformer should be connected to terminal block Z1 terminals 4 and 5.

The question will be why is the blue wire loose? has the wiring been bodged or was it just accidentally pulled out when the mains cable was removed.

Dont worry about the neutral. With 3 phase there are two ways to use it called star and delta. This link has a reasonable explanation **LINK**

Thread: Electronic switch forward/reverse/stop help
25/05/2019 07:41:17

Hi John,

Did you get it working?

I have reassembled that type of switch several times, very fiddly. Have you checked each contact is working when it should with a multimeter?

It looks like your switch is by Kraus & Naimer somewhere on the black lump should be a part number.

On page 58, Power Failure Release is what you need.

I also searched "kraus & naimer distributors uk" lots come up and they have a UK office too.

Thread: Getting rid of the garage door...........

Advantage of leaving the garage door in place and walling behind is no one knows it is a workshop. Not having a window gives you better security and more space.

Hi Pete,

Welcome, I found retirement the perfect tonic for an erratic pump, hope it is suitable for you too.

Thread: What are these change gears for?
24/05/2019 15:05:51

Ahha, that is exactly what I have This site has a picture

12 years ago I helped my wife clear her step fathers workshops. Most had already been sold off, the bulk of the remainder was red rust thanks to a leaky roof and a break in. Heart breaking seeing the slip gauges over the floor in a rusty puddle. Now seeing that Sabel I realise that was the rusty mound in the corner. I did look at it and wanted it, but at the time did not have the space. Oh for a time machine.

Thread: HSS or CS taps and dies
24/05/2019 14:50:59

I just moved some more things from my old house to here. I found that I have a brand new set of Halfords taps and dies. Havnt a clue where it came from, but along with the Sherwood STP I just bought they cut the threads almost as easy as screwing a bolt in.

I also discovered that my old place was 1 mile from Cromwell tools. It must be the last bastion of storemen. Dont get me wrong they were totally polite and helpful. Just I got that feeling that I was only allowed in if I did not touch anything.

I asked for a 500g tub of Rocol RTD. He did glance at the terminal but did not touch it. I could see the contempt in his eye for automated stock systems. Of he stalks into the depths of the racking, a while later he returns with a bottle of Rocol RTD oil. I stick to my guns, and say "no the one in a tub". Of he goes again, a bit longer this time. He returns empty handed. Well I am prepared for this, I have the power of the Internet and have already looked up what they sell. What about Trefolex I say, and of he goes again. Even longer this time, more muffled thuds and scrapes and he returns with Sherwood STP and says what about this? I decided tweaking the tail of sleeping tigers is a bad hobby and agreed, yes that is perfect. I even got a smile which rapidly turned to a scowl as he aproached the terminal to make the sale.

Thread: What are these change gears for?
24/05/2019 14:27:09

While digging trough more boxes I found 49t change wheel of similar dimensions that meshes fine. In the casting it has an embossed diamond with S&B. Could that be Smart & Brown?

24/05/2019 11:40:48

I have a 127/100 combination gear that I am trying to identify what lathe it is for.

DP 18

PA 14.5

Shaft 5/8"

127t thickness 3/8"

100t thickness 7/16"

Overall thickness 13/16" ie same as 3/8" gears with 1/16" clearance.

Any one know what lathe would use this?

Or rig up the garden hose so it simulates heavy rain on the house. Then you will be safe in the shed, bad weather is always a good casual visitor deterrent.

Thread: HSS or CS taps and dies
22/05/2019 07:40:51

I dont have a specific tapping guide, but I do have a selection of Eclipse tap holders. They have a centre hole in the top, and I have made a centre to go in the drill chuck. I have a spring loaded plunger centre on the todo list, but that might just get replaced by a length of bunge tied to the drill handle.

21/05/2019 19:37:30

Hmm tapping compound, when I was at school we had a pot of tallow, and happily my father had a similar card board pot too. I have used lard in the past, but since my move all I have is neat oil.

I have seen people mention Trefolex and Rocal any other suggestions?

Regarding tapping drill size. For M6 I have two books, one says 5.6mm the other 5.3mm. I am tapping a 19mm deep hole so chose the 5.6mm to reduce the thread percentage and make tapping easier. For relatively deep holes what percentage thread would you use?

I dont know what they are like but I came across them in a back issue of MEW the other day. Fenland Castings

Thread: HSS or CS taps and dies
20/05/2019 17:56:02

Thanks for the advise. I have always bought reasonably priced tools, then if I use them enough to break/wear them out think about buying a better quality ones. It sounds like CS will be fine for me at the moment, I will only work on brass, mild steel and CI.

I have never looked at the tap and die company, I will give it the once over. The reasons I picked TT were I have used them before and they offer a loose set of taps/dies. I have a draw full of tap and die holders, don't need any more.

20/05/2019 12:58:48

Up to now I have used inherited imperial taps and dies, all of which just work perfectly.

Having just wasted £15 on a set of metric cheesium which went blunt after 3 turns in mild steel. (I know I should not have bought them but i wanted to make some T nuts to get started on my mill)

I am now looking at getting some reasonable metric taps and dies, and recently have been reading Tubal Cain's book about hardening and tempering. In that he says that Carbon steel can be harder than HSS if kept cool. Hand cutting a thread at most will only get warm, so what would be better, CS or HSS?

Looking at Tracy Tools I can get a loose set of CS taps for £20 or £40 for the HSS, any thoughts?

Thread: oil for lubricating lathe
19/05/2019 20:31:55

My lathe specifies SAE 20 ISO 68 I bought Morris Liquimatic No 6 ISO 68 Hydraulic Oil

What you need to avoid is any oil containing zinc (ZDDP) or sulphur as they attack copper based alloys.

Also avoid engine oils, they contain detergents that keep the muck in suspension so the filter can remove it. On a lathe you dont have a pumped filter so you want the muck to settle out.

My late mother had the opposite problem of very swollen feet. She had some shoes made for her. I think she found the person thorough the local health care.

I guess she would not like to do Internet shopping. Google turned up **LINK**

Thread: Rust removal methods safe for cutting tools / precision parts?
19/05/2019 18:07:27

I have just tried citric acid to clean up some rusty tool makers clamps, very impressed with the result. Actually it was Ecover toilet cleaner 1:4 with hot water.

I after scrubbing I soaked them in a solution of sodium bicarbonate to neutralise any remaining acid and then a light oil.
