|Thread: Mini lathe feed|
If you look at picture 29 it only shows 1 half nut.
If there is a swarf guard over the top of your lead screw there may only 1 half nut fitted.
|Thread: Cross slide adjustment?|
The below quote is from a Wm290 thread on this forum.
It would appear they have gone to a tapered gib to accommodate the DRO fitment.
|Thread: C0 Lathe Blowing Fuses. Control board short?|
The link should show a circuit diagram of a controller board, unfortunately not yours. The guy is John Swift and is on this site but is dated 2010. It may just give you some idea of what you are taking on.
|Thread: What Did You Do Today 2020|
Having a go at making a Psudo G71 Roughing Cycle for Mach3.
Not had the courage to try it on the lathe yet.
Going to wait until I do the corresponding G70 so what ever I make will be finished to size.
Not sure how the tool nose compensation will work out.

|Thread: clarke cl500 improvements|
Great stuff John.
It's a nice feeling when you modify a machine to make it work for you.
I have a Chester Mini Lathe which also get a kicking but you can't beat them for the money.
The mods I have done are to make it more like the machine I want not because there was anything wrong with it.
The Great Sage SOD was saying £20K for a model engineers lathe with all the bells and whistles but who would pay that much money out?
|Thread: BBC Micro Boxford TCL125|
How's your refit going?
Glad you mentioned about the contactor drive being on he stepper board, I hadn't realised.
With that in mind I have bought a 6 axis break out board with 3 relays.
I have got my tool turret mostly fitted just need to fettle M6 to M5 screws. I rejigged the turret driver software from my Denford and it seems to be working.
Does your cable plug into a board like this?
From memory(very dangerous). I removed the board and made my own interface PCB which then plugged into a generic 5 way break out board which then went to mach3 through a parallel cable.

|Thread: strange power socket|
Wish I still had the fork with the bent prong! My mother kept it as a reminder.
I think that is why they eventually went to the shutter type of domestic socket.
On here they call it Darwinism!
|Thread: Dam Solution?|
Using a siphon would only require energy to prime it then it would run for free.
|Thread: Electric Cars|
You answered your own question.
This would be my take on it, unless they are going to program in male aggression and selfishness.
The cars would agree amongst themselves who would be first away from the lights.
|Thread: spindle bearings|
I got chance to fit the bearings today. It's not good.
Spun up the spindle in the lathe so only the ACB's were spinning, you can hear a noise and feel a vibration.
If you let go of the hub the noise and vibration disappear.
So it looks like I will have to dig deep and buy a pair of matched bearings.
The cheapy bearings arrived today. I spoke to Ketan and he gave me some advice on fitting the bearings so will see how it goes. Probably fit them at the weekend.
Have to agree with the bit in bold. Whilst playing I filled up the knackard bearings with grease and couldn't believe the increase in temperature at 3000 RPM, burning hand temp . As expected the bearings were growling. I stripped it back down and washed out the grease and just used a sticky oil and it then ran barely warm.
Hi old mart
Thanks for that.
The bearings in my KX3 are I believe are a cartridge type. The markings on the bearings indicate they are a matched pair (7007C). In the first instant I am going to fit a cheap pair of angular contact bearings and try and find a way to apply a preload. They are back to back bearings so preload is not guaranteed. Thinking of dropping a shim in between the bearings, press it all back together again then do a spin test, tweek the adjuster nut until there is slight drag then lock up the nuts and test. Otherwise its £170+ for a matched precision pair!
How did you get on with your bearing replacement?
I am in a similar position with my KX3, it took a hard dive into the job and took out the bearings.
|Thread: Honing motor cycle small ends|
"I used to fit and ream the pin bushes on victa engines and used an old piston as a guide for the reamer to help keep it square , i used to have a piece of plate that fitted over the cylinder mounting studs and it had a slot cut for the conrod so i could sit the piston skirt on it and line the whole lot up and slide the expanding reamer in".
You should win the John Stevenson Bodger award with that one.
|Thread: The Chocolate Fireguard as designed by Mercedes Benz|
I believe I.A.M's recommend being in gear at the traffic lights so if things go pear shaped there will be some measure of control, I did query that this meant the engine wouldn't switch off and the reply was safety takes precedent over emissions.
