Thread: Diametric Pitch

Posted by richardandtracy on 19/06/2017 16:03:22:

I have BS 436: Part 1:1967 on my desk at the moment. It's 'Specification for Spur and Helical Gears... (diametral pitch series)'

So I can confirm it's been 'diametral' since at least 1967...



Since at least 1955, according to my earliest Machinery's Handbook.

Google "Stargazers Lounge", which is great site for amateur Astronomers; you will find a lot of good information about equipment there and advice from experienced observers.

Wow, what a jewel !

I remember seeing a Rolls similar to that for sale for ten thousand dollars at the Rose Bowl swap meet in California back in 1970. There was also a gull wing Mercedes for sale for fourteen thousand at the car show held on my High School's football field the same year. If one could only have speculated their future value and desirability in todays world.

+ 1 for a longer list. It would be nice if "all" the advertising was on the Home page, with a bypass on the Toolbar to click onto to get to the meat of the forum.

Thanks for posting, I wasn't aware of the event; not too far away either.

Use Lacquer Thinner to tap aluminium. Learned this 40 some years ago from an old machinist at Lockheed Aircraft.

And here is a view of crank and slider mechanism. It would be interesting to see an internal photo of Tractor Man's filer for comparison.

Here is a photo of the filer's guide wheel & track.

I had a look today and was able to see the elongated slot in the flywheel where the connecting rod is attached. There doesn't appear to be any index marks to designate stroke length, so I guess you just adjust it by trial & error. Here is a photo.Opus 120 Die Filer

Rozalex Barrier Cream,

- if you can find it, Mole Valley sell it, or did, always used to be good. They do wet and dry versions. Used it for years when I was at sea in the MN in the engine room.


Thanks, I'll look for it ! yes

Mike E.:

As a barrier cream for dry (ie not involving water) work I have found nothing to beat PR88; certainly not cheap but very economical used correctly.

Thank you. yes

At present I am using barrier cream; mainly as I'm working with cast iron on the Stuarts kit S50 & as we all know the cast iron gets into the pores & creases in your skin so it makes for easier clean up afterwards, I also use disposable latex gloves as first line protection with cast too.


What is a good economical barrier cream to purchase ?

Cheers, Mike

Very nice miniature models William, Well done !

I don't have game consoles either, never have. If my Dad were still with us today, he would say....... Live a real life, not a virtual one.

Hi MikeE, to adjust the stroke you open the long narrow door at the upper left hand side, inside you'll see a flywheel with a 19mm spanner size nut with a bearing & a tee slot just like a shaping machine which you slide nearer the centre for a shorter stroke & outer for a longer stroke.


H Graham,

When the filer was delivered I noticed the narrow cover on the left side. I popped it open for a look, but couldn't see much as I didn't have a torch at the time; I'll check it out.


Thread: A Filing Machine with motor drive

If it's of any help, the stroke rates for an old industrial filing machine I have are 70, 110, 150, & 280 strokes per minute.

Hi daveb, The pulley system only controls file speeds, and the hand wheel operates the pulleys by a long vertical screw. I just don't see any adjustment device on the surface of the machine to vary the stroke length. I have a shaper, so I understand what you mean about the sliding block, which makes sense. I now think the adjustment is likely to be inside the main casting, which I'll check it out next time I'm at my storage unit; thanks for the tip.

Opus 120 Die Filer

The 120 model of the Opus filer is capable of table adjustments of up to a 10 degree angle, but no elevation adjustment like the larger 140 model. According to the information on the site, this filer is supposed to have a stroke adjustment range of  0 > 4 3/4" but I can't see how to do it ?  The only control beside the on/off switch is the hand wheel for pulley tension & selection. Opus 120 Die Filer

The tailstock seems to be reversed, and by the addition of a belt drive on it, it looks similar to a glass blowing lathe.

Thread: Centec 2 drop arm dimensions or for sale

Have a look on the used tools site, and scroll down to the very bottom of the page. Currently they show a pallet load of Centec parts which includes an overarm with an arbor support. You might want to give them a call to see if its compatible with your needs.
