surely IR ( infra Red)

Thread: Ebay site changes for the worst
18/09/2019 18:04:45

Its when the seller gets friends or acquaintances to bid on their auctions to drive the price up

17/09/2019 20:29:10

Not done it yet

its only changed in the last few days

you used to be able to click on bidders in an auction and see what categories and sellers they had been bidding with therefore knowing that perhaps shilling was going on

I think you are meaning that bidders full names have been hidden that was a few years ago

17/09/2019 15:51:47

Has anyone else noticed that you now cant check other bidders who are bidding on auctions to see if you are being shilled.?

Thread: Any one used a digital microscope for micro turning on a lathe

Well as i said it stays where its put

its sprung and counterbalanced if you knock it it moves but it swings every which way and lifts up or down and stays where you want it

I think this one was Very expensive new designed for a large heavy monitor on a desk

This my scope mounted on a monitor stand clamped to the ceiling joists its easily moved to wherever i need it

as i recall this was <£20 on eBay and stays where its put

This scope has a working distance of 7 inches from the ring light and fills the frame with my fingernail

I use a Zeiss operating theatre stereo microscope in my workshop mounted on a boom for the small things i do

it works great

I think that using a digital device means looking at a screen rather than live at your work /tool interface and there always seems to be latency problems with electronics

Thread: Repair required for Milling Knee
05/09/2019 12:55:11

Well i would clamp it together and assuming that the parts fit well together drill and bolt it with about 4 m8 or m10 bolts if you can get them in

use it and look for another machine to use for parts

i weld cast iron regualrly but thats a difficult one would need machining the dovetail after welding

Thread: Colchester student feed issue

Yes when the chuck is turning

if the forward /reverse traverse lever is set

if the gearbox is set the lift up handle one

if the abcd levers are set

then the feed shaft should turn

set the imperial/metric lever and the lead screw should also turn


Do you have a gearbox for screwcutting?

Edited By Ian Parkin on 03/09/2019 11:53:43

03/09/2019 09:08:32

The feed shaft will only rotate if the gearbox is set

the only one that doesn’t matter is the metric/imperial selector

and forward /reverse lever needs to be set to one or the other

but the feed shaft will /should always rotate if the above is done

Sorry just reread your post it will only run when the main spindle is turning

motor turning may have a clutch

Thread: Just for fun what’s this stuck in my tyre?
28/08/2019 10:18:07

David i did wonder if someone had done that

but up here in the north the streets are littered with the little blighters

28/08/2019 09:23:55

Yes he was quite rude when i pointed out his rear brake linkage wasnt much good.

This is whats wrong with not having to have a mot for over 40 year old vehicles

people change things with no real idea of the consequences of their actions

17/08/2019 15:04:10


Says it tax and mot exempt 

professional job

always passed mot’s

He’s asking 8K for it

Just seen this bike advertised on a local forum

have a look at the rear brake actuating rod..

wouldn’t want to be relying on that in a panic stop
