Thread: GHT Rear Toolpost 8deg milling cutter
31/12/2020 22:29:36

Have to say that John and Clive’s are just the same as mine and it worked very well and as they say not difficult to make.

Thread: Obtaining Serifed steel punches

Bill, Mine are 1/4sq punches and they are held in a George Thomas holder

I have recently bought 1 mm sets from Pryor and use them in a jig and they are all perfectly aligned. When I bought them I asked about alignment and they assured me they were perfect and they were.

Phil have look at ever hardware.com they have chart with blank sizes

Thread: Toolpost grinder for ML7
11/12/2020 22:53:30

Martin, you admit it will be the odd job so why would you buy a commercial tool post grinder for £xxx when as people have said before it can be done another way. Myself I use a circular mag chuck and a dremel or my tool post miller with a wheel attached. I use it for grinding gear blanks and washers and with the measuring gear that I have I cannot find any runout on thickness. just make sure to protect your lathe. Also see mew article on grinding chuck jaws, informative and it works!

Good job they don't come to the county where I live!!

Thread: Drilling then Tapping in Drill Press
11/12/2020 11:23:33

Sorry Andrew but if you are using a 5.3 mm drill for m6 tapping I would hate to see your percentage of engagement figures!

Thread: edm machines

Mark, From my original request for info in April 2019 I decided to go the Ben Fleming route but have to admit that I have not achieved very much, just collected a few components and done a little on the hardware so perhaps I’d better join that club!

Google spring tap guide you will be spoilt for choice

Thread: co-axial indicators
30/11/2020 21:44:40

6dbf7fcb-cf00-40ff-a368-f4334e879ac6.jpegb9906cbc-1406-4979-9b6f-c532f5aa3709.jpegAs I have a small mill (raglan) commercial coax indicators are far too long so made my own. The first one is my own design and the second is from an image from the net. Both work really well and making them fit close to the machine spindle saving even more space

Thread: Electric vehicles
19/11/2020 13:25:54

Sorry Jason but the ‘e’ tat is/was a farce as it was only a two lap race and you needed two bikes to do that. The last race only had about 4 entrants which led to it being scrapped for the foreseeable future. It’s fairly obvious to me that bike manufacturers are not embracing electric except for commuters especially as the tt races were usually won by private innovators.

Thread: Testing Models
18/11/2020 13:02:26

Evan , I think the o rings you are looking for are made from Viton. Just a word of warning, back in the day while still working we received a memo about not touching viton rings that had reached a high enough temp to have changed colour as they were thought to have carsonegenic properties. Not saying don’t use them just be careful.

Thread: Source of 1/2" Diameter Delrin
18/11/2020 12:54:14

With nogginend having 15 mm at £4.20 a foot why would you bother looking for 1/2 inch?. I use a fair amount of acetal and machine it with pcd tips and the finish is amazing and dead on size, personally I would prefer to start with a larger blank to give a fine turned finish to your major dia.

Thread: Evolution of a Boring and Facing Head

Projects for your workshop vol 1 from tee publishing

14/11/2020 21:48:58

i originally made the screw cutting dog clutch from grahams book about five years ago, works faultlessly. with recent lockdown the book came out again and the boring and facing head was made, a beautiful thing. Out of interest grahams drawings are the only ones I have used which so far have had no mistakes this is in itself a pleasure

Thread: Silver Soldering for the Clockmaker
13/11/2020 13:11:41

If using easy flo fluxes (not tenacity) it is only necessary to put in boiling water after making the joint.

Thread: Tri-Leva decal artwork?
13/11/2020 11:33:54

I have asked Myford in the past for this label as it is the only one they don’t supply and they said they have no plans to supply it n the future, looks like an opening for some enterprising chap £ £ £

Thread: Silver Soldering for the Clockmaker
13/11/2020 11:30:09

Don’t understand you would have to wait 12 hours to silver solder a joint, perhaps you need to talk to Keith Hale (CUP) the man has over 40 years experience in silver soldering. Went to one of his lectures and dispelled lots of old wives recipes for success and since then my silver soldering has got better and better.

Thread: Help & Guidance. , Please ! .

I made the Wilding Turret Clock and made the cutter for the wheels it turned out to be fairly easy, the pinions are lanterns which personally I think look more interesting but good for a turret as there is plenty of room for the dirt to go! I also cast the brass for the wheels which was interesting.will put some pictures in my album.

Thread: "Gearing of Lathes for Screwcutting"

You are obviously cutting metric threads if you have the 34 tooth gear fitted so why the 21 tooth. By the way they are not that elusive.
