Thread: Electric roller garage door

Consider one with an external override lock if you have no internal access from the house.

Big panels are better.

I have had a Teckentrup (Cartech) door for years, Yale lock hidden behind the makers name plate.

Needs an 8ft clear run I had to attack a brick pillar with the chisel to get clearance.never had any trouble. Fitted myself

L 6 are rare as your ad on Ebay shows, you are it. None are coming up sold either.

You've got 2 bidders, none of which are traders so they might fight it out.

L6 are just too big and heavy for transport and most shed workshops.

The lathes.co seller is a dealer, he has 3 large lathes under his name.

A lot of the cheap start/stop switches are like doorbell push switches and designed to operate a relay, you need a latching type. The number of pins is irrelevant.

Kiwi Bloke - they might be coming to get you, too! There was a report in the UK press recently that a number of UK banks are closing the accounts of ex-pats without a permanent residence in the UK. It may be that this is more relevant for those living in Europe due to the Brexit business which means the banks are no longer able to do business there and NZ operates under different rules.

Yes, Brexit has tripped it, all those expats living in Europe who have been claiming their full index linked Government pensions while still appearing to live in the UK, when they should be only getting a fixed one based on the payment when they left the UK.

Thread: MOT - am I being taken for a ride?
16/09/2022 10:45:25

I had a swelled up carbuncle of rot once which you could bounce the round end of a big ball pein hammer off all day, but one light tap from the pointy end of a welders slag hammer caused total disintegration of thick black rust and a big hole.

I have had an MOT test from a guy who used such a hammer and he showed me how. So not everyone follows the rules, but people could reasonably claim that paint damage from previous tests could have caused the premature rot so hence the rubber hammer and Mk1 calibrated ear to detect the different sound.

Thread: Lathe carbide tool issue

Not entirely related, but kind of.

Back in the mid 50's celluloid was the new wonder plastic and the brush factory where he worked made some plastic hairbrush handles.

Being works voluntary fireman he was given the task of disposing of the drilling swarf by burning.

Knowing it was a 'bit' inflammable he laid a long trail as a fuse to the waist high heap and expecting a 'petrol on the bonfire' like effect he swore it was 20ft long. What he got lighting it was a fast gunpowder effect the flashed with the near perfect air fuel mix which blew him off his feet and took all his hair as well.

The problem with the 'it'll be fine' approach is it normally will be till you miss some on the clean-up and a year later it looks just like steel and so ignore able, then you get the angle grinder or the welder out and up it goes when a spark finds it.

Thread: QCTP for WM290V

Warco sell a "Dickson" style QCTP, but unfortunately they don't seem to be made to the same tolerances as genuine Dickson QCTP's. Despite being sold as "fantastic quality QCTP's".

fan·tas·tic

[fanˈtastɪk]

ADJECTIVE

  1. informal

    extraordinarily good or attractive:

    "they did a fantastic job" ·

    synonyms:

    tremendous · remarkable · great · terrific · enormous · huge · striking ·

    • of an extraordinary size or degree:

      "she had spent a fantastic amount of cash"

  2. imaginative or fanciful; remote from reality:

    "fantastic hybrid creatures"

    synonyms:

    fanciful · extravagant · extraordinary · irrational · wild · mad · absurd ·

    • (of an object) seeming more appropriate to the imagination than to reality; strange or exotic:

So, in this case the 2nd meaning may well apply.

The ABS system is also used by the speedo, Odo and the traction control if you have it.

Intermittent faults sooner or later become permanent. Reluctor rings break for no apparent reason, but these either fail or work OK there is no maybe.

It might the worth (after checking the fuse for the dead screen) checking the cables going to both front hubs for signs of scuffs in the dirt coating which may indicate interfering fingers or someone dropping the wheel on a cable when the tyre was changed.

BTW Don't go back there next year

Thread: How much should I ask for these lathe tools?
12/09/2022 20:56:53

The trouble with lots like this is that most people's old lathes have already amassed collections from previous owners. They do make useful parallels for the mill.

Both of mine came with an ice cream tub half full of 'specials' like those.

Thread: Plant Identification … please [ Horticultural ]

According to Plant net there's an 18% chance it's a plum.

That being true, spot the nearest Plum / Damson tree and dig a trench about a foot deep (a mattock is a wonderful tool for this) as near as you can get to it. The closer you can get the shorter the trench need to be.

The damn things can sucker 40foot away from the parent tree and will keep it up for more years than we have left to us.

You don't say the size or shape of your inserts but one on the **GT inserts for high temperature alloys (not aluminium alloys) is what you need and they will take light cuts, something like this

The above is the way to go, carbide shaped like hss, just don't stall the cut.

Brazed carbide requires power and speed, which gives the heat to cut. OK on steel with big depths of cut, but not so good for a Sherline.

I had that with some from a well-known supplier, fine on EN3 but anything tougher and bang.

The tip was fine, it was the cone that let go.

Google "Braided cable sheathing" Should be what you are looking for.

Off the shelf cable sheathing as such will invariably be a plastic material.

However, the principle is correct. The cable on a domestic iron is braided in a similar material.

Many of the vintage car restorers use fabric-braided wiring harnesses, and the companies supplying the looms have the braiding machines to put any design of sheathing onto a wire (some have mostly black with a coloured stripe, for example). So if the OP can find a material (thread) that mimics the canvas of the full-size hose, they will be able to braid his length of rubber.

Having taken the trouble to look for tubular cotton braid you get this in various sizes. Note the width is the flat measurement and not the radius.

Thread: Sigma Jones / BCA jig borer
07/09/2022 10:08:23
Posted by Rob Gough on 06/09/2022 17:32:42:

Hi,
I'm new to this forum, but hoping someone can help with regard to the history of the BCA jig borer. I'm current restoring one of the Sigma Jones variants and after reading the information on the lathes.co.uk site my initial understanding was that the machines were first made in the UK as Ultra & Excel sometime around the beginning of WWII, then as Sigma Jones from 1947 and finally becoming BCA in the mid/late 50's. However, I've recently seen a Sigma Jones for sales with a stated date of manufacture of 1939. Re-reading the data I can find on-line I'm now confused. Tony describes the 'early' machines as Ultra/Excel, but uses 'also' in reference to the Sigma Jones, implying they were contemporary. But then going on to link them with the Herbert acquiring Sigma Instruments in 1947. Can anyone please clarify the periods when machine was marketed under the various designations?

Hi Rob,

This was simply badge engineering with machines spread over several named makers mostly owned by one parent as mentioned below. So there is very unlikely to be a definite progression of companies. The the same manner the Austin 1100 was also made at the same time as the Wolsley 1100 and Riley 1100.

However, even this is not certain, for it was also stated in contemporary Elliott catalogues that their machines were made: "… at the works of our subsidiary and associated companies whose whole output of machine tools and equipment is solely controlled by us." The clue lies in the word associated, for Elliot had enough buying power to commission, and then re-brand, machines from a several independent UK makers.
