Thread: Parts for Bantam Lathe
27/09/2011 13:41:54
I had assumed you had tried colchester
my parts were in the region of £ 400
the parts from moores were < £100

Hello Mike
 
I had teh same problem with my colchester student
I bought a length of acme LH thread of the same pitch and diameter and a bronze nut and made one to suit.
I bought it from

Thread: Reaming a pinion, wall thickness?
01/09/2011 19:35:54
Why doesnt the pinion fit the shaft to start with?
Is it a scratch built heli you are making?
if not what do the manufacturers of the pinion want that to fit...5.75 seems a funny size to arrive at when the motor shafts are 6mm or are some motors 5.75?

Thread: what thread is this?
25/03/2011 12:04:55
Well after all you guys fine advice, I decided to buy a chinese die to match my tap so it will be 12mmx1.0 LH and hopefully just run the die down the spindle so it will be reasonably standard then ...just the delivery time from china...it was only £8 in total though.
 
Problem with making a new spindle is thats theres a bearing cup threaded onto the middle of the spindle so making a new one of those starts getting complicated ...so if i just leave the bearing cup on the oversize thread and cut down the exposed thread on each end.

How do you accuratly check the thread angle on such a fine form?
I have lots of pitch gauges and only the 1mm fits perfectly.
what other thread form would correspond to 12.15mm and 25.4 tpi?
22/03/2011 14:32:26
Thanks for your replies guys
the thread is definately 1mm with my pitch gauges 24,25 and 26 tpi dont fit at all
Its just the odd diameter
I do have a lathe and have cut quite some threads but never left hand and so small internal..
Is anyone near sheffield who would be prepared to do the job?
I have ordered a 12mm die from china but delivery is 2 weeks or so

Hi there
I have a motorcyle front wheel spindle that I'm making some nuts for ..
Its a french 1930 terrot
the thread measures 12.15 mm and pitch is 1mm and left hand for good measure. Its in fine condition considering its age.
I bought a LH 12 x 1.0 tap and made a sample nut and no way will it go on.
What do I do? machine the spindle down to 12mm and buy a die (£ 58 eek) or any other ideas? Is it a special thread? or another I'd not considered

Thread: Taper reaming
01/03/2011 16:10:16
Not sure about the process of making one but to use ....you use one by hand turning clockwise with a tap wrench untill your taper pin fits the hole smoothly after drilling a hole to the smaller diameter of your preffered pin
Thread: Micrometers disc/paper
28/02/2011 18:37:28

A paper or film micrometer has discs on the business end of the spindle and on the anvil which stop the spindle being withdrawn through the nut...the disc is what i need to remove...or maybe its not designed to be removed
28/02/2011 16:37:08
Hi there . I have a moore and wright paper micrometer which I would like to dissassemble, has anyone any idea how the disc is held on to the spindle so I can unscrew the spindle to clean and relube...its a bit dry and tight.

Thread: Fitting a Chuck to a Rotary Table
16/07/2010 18:24:26
The way I get it concentric  is place my morse taper test bar in the hole in the RT
then place the chuck over it
clamp the jaws onto the test bar then bolt the chuck down
undo jaws and knock the test bar out

Thread: How big to make a chip tray?
11/04/2010 11:51:39
I made a largeish drip/chip tray to fit on my bench cut away holes for the handles and find that it cuts out a lot of drips and chips on the floor...I made it out of 1.5 mm stainless...perhaps overkill but no probs with rust .
