Thread: WARNING Scammer

Nothing wrong with putting cash only for collection items

you have to offer paypal you dont have to accept it

it would limit your buyers immensely if you didnt take paypal for postable items

Thread: Blowtorch problems
19/09/2020 20:19:33

I’ve ordered a repair kit @ £29 rather than a new torch at £95

the only bit it doesn’t include is the black body casting by the looks of the kit

19/09/2020 19:23:01

The jet is clear

the air holes are open

if i turn the gas knob down i get a good flame but not a fierce flame like i used to get


19/09/2020 18:54:56

Any ideas why my rothenburger blowtorch has suddenly started refusing to ignite in spite of what looks like a good spark and also the flame is like this


Rather than as before the flame went down to the end of the nozzle

it just started doing this having been fine for well over 6 years

Thread: Ideal Guillotine
18/09/2020 05:23:09


the guillotine in my video actually tried to cut through a steel ruler and it shattered the tungsten blade about 4 inches in length

blades are about £1200 so expensive mistake

ruler survived

never seen any wrong material detectors on any paper cutting guillotines

Thread: Tachometers sensor magnet
17/09/2020 16:30:57

I did the job today just ground a flat on a 20mm silver steel shaft and placed the magnet and it stays there even at 1000rpm

its been running an hour or so now

I had it in my head that a magnet would have need putting in a non ferrous collar to work adequately

thanks for all the help with this

Thread: Ideal Guillotine
17/09/2020 16:26:34

I was at one of my customers and did a short video of a real sized paper cutting guillotine

this is a polar mohr Guillotine with side lifts air tables jogger and palpating attachments

see how easily the operator moves around perhaps 80 kg of paper and the power with which the machine cuts.

this has a 5kw motor spinning up a flywheel weighing 300 kg

the knife in this one is a tungsten tipped blade which lasts about 2 weeks whereas a HSS one would only last a day or so

i don’t know whether i can post links now but search on YouTube for “polar guillotine sheffield”

Can i post links to my video’s?

15/09/2020 21:34:00

Blades easily available but about £150 now

its probably a 1980’s machine that one so not old

Thread: Tachometers sensor magnet
15/09/2020 18:22:14

I need to fit a tachometer on a machine in the morning

how do i fit the small button magnet to a shaft?

if i glue it to a mild steel shaft does the steel sap the magnetism ?

Thread: Ideal Guillotine
15/09/2020 18:19:02

I worked on the electric versions quite a lot in the past

the manual ones don’t really have any safety features as such

the blades are either carbon steel or high speed Steel on ideals so not hardened

anything you need to know ask away

blade sharpening at a couple of places in sheffield

Thread: Mk1 Colchester student clutch
09/09/2020 19:54:14

The clutch if fitted is outboard of the pulleys away from the headstock

dsc02094 (medium).jpgYou can see it out of focus behind my home made brake...if you have a clutch you cant have a brake usually

08/09/2020 16:11:14

You can have a clutch fitted

does your motor run then when you lift the start handle the spindle starts?

or when you lift the handle does the motor start? And the spindle?

if you don’t have a clutch you should have a brake in the pulley area which could be giving problems

but first I’d look at your drive belt/s

The list of prohibited items is all encompassing there’s hardly anything that they will carry

i can imagine if you sent a glass item and it got damaged then that’s ok you lose. But if they lose the item what was in the package is immaterial...they lost it

Thread: Moore & Wright disaster
03/09/2020 12:57:50

Barrie you are right

i misread the listing

03/09/2020 12:12:24

If anyone needs new batteries they are



4.8v 250mah

Edited By Ian Parkin on 03/09/2020 12:12:35

03/09/2020 12:10:38

I just received 2 new batteries today from “all batteries” for my 2 micro 2000’s

these are a direct replacement but lithium ion

cost £20.30 for 2 delivered

anyone any idea how long I should charge for and is it ok to keep plugged in when not using?


Thread: Can anyone supply a lead for grub screws
23/08/2020 13:25:45

For now I’ve punched out some 2mm thick brass pads and the operators will have to drop one of those down the holes before using a normal grub screw

the machine maker wants £12 each for the brass pad ones

23/08/2020 10:51:49


do you mean drill the grub screw and turn up some brass pads?

can I drill a grub screw?

23/08/2020 10:18:20

I need 20 of these?

5/16 unc with the brass pad

Any ideas?

I still have a very space age looking pack (bright orange with fins) that I bought in 1986 and its still working when I need it.
