|Thread: Taig Backshaft Project|
Just wondering what you are doing to warrant 50 rpm? I spent my time on the bearings etc to get it to 9800rpm, fantastic for 1mm shafts!
|Thread: Running needle roller bearings|
If it’s for a hot air engine where friction is your enemy would you be better to use ball races, much less contact area than needle rollers. And you can buy them with different clearances.
|Thread: AA batteries|
I thought it was more that the battery boxes in stuff made in you know where are a bit scant on dims. American stuff that takes batts is ok, or mine is!!
|Thread: Are these Flexispeed accessories?|
Blimey Neil that was a long time ago, I’m a norwich boy and have a hard job remembering that!

|Thread: Centre Drill Leaves a “Pip” - Sometimes|
I’ve taken to using 3 mm carbide drill shanks with 3 facets ground at 45deg leaving a sharp point at the end, it gives you a lovely small divet for the drill bit. Cancer machines use this method for small holes and you should see the price of the bit or not.
|Thread: New Chuck won’t screw on|
All backplates that I have bought from non genuine suppliers have needed work!!!
|Thread: Lumps of aluminium and brass|
Find a local machine shop go with a couple of tenners in your pocket and you go home with headlights pointing skywards.
|Thread: Rotaform spin fixture collet ID competition|
Photo could be handy.
|Thread: Testing the Euro / IOSS|
|Thread: Lathe cover|
No covers use hydraulic oil as cutting oil problem disappears
|Thread: Milling on a Lathe with a Vertical Slide|
I’ve found that if you have to use through punches do not hold them at the end hold next to the material.
|Thread: Mystery micrometer|
The second photo looks like it could be set in tube Mike configuration.
|Thread: Bearing Location - Pulley or mounting block|
As a Peatol user I am interested to know the use of this. Personally I would have the pulley fixed to the shaft and the bearings fitted to the block with retaining caps/plates/screwed rings. If the block is bored with a hole clearance size for the shaft and a stepped bore for the bearing minus 5 thou screwed cover plates would do the job and make for ease of maintenance.
|Thread: Powder coating quality of finish|
Apparently it’s the time taken to heat (slowly) that has a big bearing on finish, a company round my way I use gets a finish like glass!
|Thread: Drill sharpening?|
After you have done your 4 facets put a secondary point angle in and your drills will last even longer!!
|Thread: Randa lathe missing back gear|
Out of interest flat drive belts are still made, they are made from a modern oil proof material and usually coloured green. Try transmission suppliers/ bearing suppliers like Hayley’s etc.
|Thread: Tool post height|
You could also mill the bottom inside edge from the toolholder, I believe they used to sell them already modified.
Why would you weaken the tip holder?
|Thread: advice old British motorcycle|
Best of luck by the way you can't beat the grin factor.
