Thread: Junior Hacksaw Blades
15/09/2018 08:12:31

I thought I was buying Eclipse but as the tooth profile was 'rounded' and they could be tied in a knot I doubt they were the genuine article. Beware.
Luckily a neighbour is issued blades at work and he gave me a box full.
No name but excellent blades.

Thread: Is there something wrong with this vice?
14/09/2018 08:23:59

Maybe Hemingway do a set of castings to build a bolt shortener?

Try a different wifi channel?

Thread: Belt Driven Hacksaws -
24/08/2018 08:41:48

Absolutely nothing to do with the OP's problem but...
I once helped 'Old Mo' in renovating Crabble corn mill.
A huge long flat belt was called for, almost the length of the building.
The lads couldn't get the pulleys set right so Mo was called upon (did his time as a mill&engine wright).
He ordered all the windows and doors shut, then rigged a little motor to spin up the driver pulley.
He took his trusty oil can and squirted a dose of oil onto the spinning pulley.
A line of oil shot down the shop along the floor and up the far wall.
"just line up on that lads", and walked out

Brushes need attention maybe?

Thread: MS 3mm x 25mm rivets?
04/08/2018 08:38:17

Thank you people, I shall report back.

04/08/2018 07:45:41

A friend is looking for some 3mm x 25mm MS or soft iron rivets.(or 1/8 x1" )
None of the usual suppliers seem to stock them any more?
Anyone know a source either mainland UK or Eire?

Thread: What did you do Today 2018
31/07/2018 08:35:22

Nice Dob Neil, good size for light grasp and portability.
I use my homebrew 10" F6 more than the refractors.
First light yet?

Thread: Homemade Grinder Advice
19/07/2018 08:33:44

Yes, I use a diamond wheel for tool grinding, mainly carbide tools but most things in my shed get a touch at some time.

Have you looked at the battery powered grinders available..? maybe something could be adapted?


We had a little homemade grinder 'out the back' in our old works, it was rescued from a skip.
It was made from a Picador spindle and a little 1/4 hp motor, only took 4" wheels.
The main problem was keeping grit out of the bearings, the shaft rattled around like a stick in a bucket.

Thread: Any tips for Machining (turning down) a Hardened (60c) shaft on a Myford 7
12/07/2018 08:20:30

60c shaft, was it induction hardened? could it be annealed?
Sounds like you'll be removing the hard case anyway?

Thread: How can I drill a deep, non-standard, small diameter, hole?
09/07/2018 08:46:03

I bow to greater knowledge and experience but I would drill to say, 0.25mm with a commercial bit, then make a finishing drill from a suitable sewing needle?
Failing that, broach it out to a fit ?

Thread: Milling table regrind
06/07/2018 08:22:35

Any engine recon firms near you?
Our local firm shut down after trading for three generations. Very little they couldn't do 'for a drink' - probably why they closed? :-/

Thread: Clock making for the penniless?
03/07/2018 08:55:41

My first foray into clock making was the Dark Lady project covered in the 'Clocks' forum.
Mine was made from scrap mostly with just a few materials bought as I went along.

27/06/2018 09:02:26

I bought a cheap set from Aldi, still going well after 6 years (1 M3 tap replaced)
Not absolute top quality, but only £13 at the time.

Thread: Another bandsaw blade question
25/06/2018 09:19:09

I am sure TuffSaws would have something, I have always found them most helpful.

Thread: Oil for micrometers
23/06/2018 07:12:29

I have used the 'dry' ptfe spray with success. Nothing to oxidise and it gives a good 'feel' for me.
Price varies from £3 to £30 per can, I happened to have some wd40 ptfe in the shed left over from a job.

Thread: Meteor detecting
18/06/2018 07:46:58

Have you tried it on Jupiter yet Neil? or the sun?

Thread: The Workshop Progress thread 2018
13/06/2018 08:36:51

A quick soak with oven cleaner?
Don't leave it on ally too long.
(and don't ask how I know this)

Thread: Governor pulley belt
13/06/2018 08:11:18

You might try a cassette tape recorder (or vhs recorder) drive belt?

They come in all sizes, in square or round section.

I used one on Lady Stephanie for the governor drive.

Nice Crayford Neil, shame John Wall isn't around to see it.
