What are you machining?

[Rannsachair]

^^^ now you need to make a new screw, that one lets the job down

I cheated

What no button heads

What no button heads

It is M4, never had a stainless button head that small on the shelf.

@Rannsachair probably a trick of the light but the first two pictures make your lead screw look well mullered.

Do not fear, just the light from the LED battens I think.

Reground the two chipped ones and a test cut on aluminium, finish as good as a new one, After cutting the hard stuff had bright orange sparks flying off, did not seem to wear the inserts at all.

I noticed that too. Lol

As a hang-up from the olden days of religious zealotry, there was recently a 4-day weekend which I thought I'd occupy with a few odd jobs on the car and bike (that are probably not going to see much use this year ). Among them was a leaking thermostat housing on the Rover V8 in the TVR.

After another fruitless search for a suitable replacement I decided it was time to stop dithering and just bloody well make one. Owing to data restrictions I won't upload a string of photos, apart from a taster, but you can see the whole saga on my website at

It looks a bit like this:

 

[Wedg1e]

You need one of these......

What are you wearing?
It's my new ruff, my Lord.
You look ridiculous.
Really? I think it makes me look rather sexy.
It makes you look like a bird who's swallowed a plate. What do you think, Baldrick?
Four!
What?
Some beans and some beans is four.
Baldrick, we've moved on from elementary arithmetic to basic dressmaking. What do you think of Percy's new ruff?
I think it makes him look like a bird who's swallowed a plate, my Lord.
No, no, that's what I think. What do you think? Try and have a thought of your own, thinking is so important, what do YOU think?
I think thinking is so important, my Lord.

etc.

First attempt at brazing a trepanning tool on some tube. Insert moved while brazing, so may have a lot less external clearance than I wanted. May need to reheat and move it over.

Trepanning... isn't that the ancient art of boring a hole in the skull to relieve internal pressure?
As opposed to trephining, which I believe is the delicate art of sticking a red-hot needle through a black fingernail to learn new swear words

Indeed it is. He must have one helluva headache to consider resorting to that.

Almost done Im going to bolt it to the 35mm bar after turning it down to 16mm for a holder.
I did try reheating and pushing the insert over, no chance. Diamond wheel ground the insert down on inside.

Mrs Grim wanted a dumbbell.

5.3kg, ends are threaded M12 so can screw on extra weight if required.

That finish is straight from the tool.

I wanted a 50mm radius on some bar, this felt quite scetchy.

The tape to stop parallel jumping free, it tried!

Almost fits

Soppy apprentice did that trick, trouble was the Burke decided to use a pillar drill.
Leave outcome to the imagination

I drilled straight though my mates thumb with 1/8" drill while holding a frame together. I did ask him if it was clear. He retorted with’ just get it f’in drilled. Sure enough 20secs later choice words from him, could hardly blame me

Took 5mm off the bottom of the Posh Grooving Tool I bought a couple of years ago at a carboot - Chinese EvilBay inserted carbide face mill did a good job on the Horn tool holder, a few sparks flew... Holder was through-hard, the burrs left defeated a cheap file, had to bring out the posh branded ones!
Then followed up with trying it putting a circlip groove in a bearing outer race to see whether I can get around the Unobtainium bearings in the Holbrook QCGB - some nice glowing ribbons, impressed by the Horn tool!
