|Thread: Fiducial lines on a Zeiss Microscope Eyepiece|
surely IR ( infra Red)
|Thread: Ebay site changes for the worst|
Its when the seller gets friends or acquaintances to bid on their auctions to drive the price up
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
Has anyone else noticed that you now cant check other bidders who are bidding on auctions to see if you are being shilled.?
|Thread: Recommendation for Tool and Cutter Grinder|
+1 for me too
|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|
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
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 no...it may have a clutch

|Thread: Is the price of this model boat at all realistic|
Well that’s £30 accounted for....
This popped up on ebay
|Thread: Not Your Modern Lathe Tools|
Hendo’s Was indeed made in the building on upper Hanover until a few years ago
now production has moved to a modern unit just off sheffield parkway
|Thread: Just for fun what’s this stuck in my tyre?|
David i did wonder if someone had done that
but up here in the north the streets are littered with the little blighters
David Davies was right straight away
a NO cylinder
I noticed this the other day stuck in my tyre driven about 50 miles on it...still held air over the bank holiday weekend
what was revealed when the fitter removed the tyre ?
|Thread: Motorcycle General Discussion|
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
Says it tax and mot exempt
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
