Thread: Taig Backshaft Project
28/07/2021 09:31:07

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
28/07/2021 09:27:13

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
27/07/2021 13:56:47

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?

Thread: Centre Drill Leaves a “Pip” - Sometimes
23/07/2021 20:45:06

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
21/07/2021 18:24:17

All backplates that I have bought from non genuine suppliers have needed work!!!

Thread: Lumps of aluminium and brass
14/07/2021 21:21:24

Find a local machine shop go with a couple of tenners in your pocket and you go home with headlights pointing skywards.

Photo could be handy.

Thread: Testing the Euro / IOSS
14/07/2021 21:14:50

What’s IOSS.?

Thread: Lathe cover
14/07/2021 21:12:23

No covers use hydraulic oil as cutting oil problem disappears

Thread: Milling on a Lathe with a Vertical Slide
14/07/2021 21:09:08

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
11/07/2021 11:45:00

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
10/07/2021 14:56:31

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?
08/07/2021 21:12:04

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
07/07/2021 09:03:27

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
07/07/2021 08:57:20

You could also mill the bottom inside edge from the toolholder, I believe they used to sell them already modified.

06/07/2021 19:16:20

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.
