Looks a nice example!

Thread: Annealing stainless steel
30/06/2019 21:22:44

Thanks for your replies.

I have attempted to drill (slowly) and it would appear to work harden very quickly.

The existing holes present would appear to have been punched, shall have another attempt with a shorter drill this time as I broke the first!.

If it isn't austenitic s/s and I heated it to those high temperatures followed by a quench could that turn it harder/more brittle?

I need to drill some 1mm holes in a stainless steel watch bracelet clasp, exact grade unknown but of Russian origin.

Didn't get very far with the first hole and wondered if it can be annealed? and thought I'd ask before turning it all black! (although it could be cleaned up)

Thread: Odd sized strong bar
19/06/2019 21:54:47

I've got one exactly the same!

It wouldn't fit anything, but it does now as I have made it fit! Just take a suitable amount off two faces.

Thread: Silver soldering cast iron?
19/06/2019 09:38:48

Thanks Hacksaw! The cast one I have is quite a nicely made lump and should suit my purpose well.

Thanks, I though it could be a problem as there appears to be so much carbon? I think in view of this pieces shape, quite a large 'cup' shaped casting I might be better off making a mechanical fixing to the alternator.

I am modifying a Suffolk centrifugal clutch assembly to drive an alternator which would ideally involve silver soldering my assembly to the cast iron clutch outer.

Never tried silver soldering of cast iron - is it likely?

Poetry in motion! Cracking looking engine, and my favourite, a nice slow Rickover.

Great job.

Thread: Need to drill a hole digital caliper
07/06/2019 13:18:10

I've encountered similar material although not a caliper and managed to drill through with a masonry drill.

Thread: Ebay 'photos'
06/06/2019 17:58:55

Quite agree, not just lathes - most items, even most smartphones to a pretty good job these days.

Thread: Myford ML7 - Size of Mandrel Through Drilling?
11/05/2019 16:02:28

I've got 0.594 on a ML7 s/n K16170 and seems pretty parallel.

Thread: 1959 Nsu quickly

I think if you have an image it could probably be printed onto vinyl wrapping type material - self adhesive, very durable, worth contacting some vinyl/sign companies.

Thread: Painting 5" gauge wheels.
16/04/2019 12:07:39

Not a loco wheel but a flywheel, although similar!

Painted my Centaur flywheel (about 7 in dia) with a spray can of satin black, I think it looks great. Casting surface prepared by filing and Emery cloth with any imperfections filled with JB Weld all sanded back then 2 or 3 coats (by brush) of Bonda Primer which has good solids content.

Rubbed down carefully with 400 wet & dry (wet) masked up the 3 coats spray black.

Thread: Notre Dame

We were there only a couple of years ago, wonderful building, such a shame.

Thread: Using a propane cylinder for partable compressed air.
04/04/2019 21:41:32

My first compressor was home made using an ex gas cylinder.

Cut a 4 inch hole in the end and welded on a heavy ring to take a bolted on flange for all the fittings.

Welded a frame on top to take large motor and pump and a frame underneath for wheels.

Hydraulic tested it to 300psi and used it for years - did me proud!

Thread: Have your fathers habits rubbed off on you. Just for fun
29/03/2019 17:16:11

Reminded me of my Dad over riding the strimmer safety switch (didn't work) replacing it with a round, brown domestic light switch!

Favourite saying when tidying something up was 'take the dairy off it' , use it myself and people wonder what I'm talking about!

(Not sure where it came from)

Thread: Home made disc sander
28/03/2019 19:07:36

It's got that headstock look about it, wood turning origin?

Looks useful!

Thread: Any Recent Progress in Induction Heating ?
27/03/2019 10:17:01

I recently saw on the tube induction heating of tyres for locomotive wheels where a loose coil was wrapped round the tyre which was fed with hundreds of amps, the tyre went blue and fitted nicely!
