British Standard Conduit.

**Vann** · 9th November 2021, 02:47 PM

Hi.

I have a number of used conduit fittings in 5/8" and 3/4" British Standard Conduit - also a few bits in 1" BS Conduit.

I do not want to dispose of these, rather I would like to make these available to fellow formites to help complete old British and Australian machine restorations. In other words, convince me that you need an elbow to complete at job, and it's yours for the cost of postage.

Fittings include tees, elbows, round junction boxes, and back nuts.

I also have some shortish lengths of 5/8" and 3/4" conduit (and BS Conduit dies). If you need a short length, let me know the exact measurement and I'll cut a piece and thread both ends - again, yours for the cost of postage.

Here is a pikkie taken during the conduit rebuild on my Wadkin LP.

And a few pikkies of the replacement conduit on my Preston bandsaw (and pictures of the ugly modern PVC conduit it came with):

Sometime modern conduit just doesn't look the part.

I still have my 9" buzzer to do and a re-route on my PK saw.

Like I said - I'm not wanting to dispose of these fittings, but if you are wanting to retain/rebuild the original conduit on an older machine, and are thinking "Where the heck do I find the obsolete fittings I need?" - I have some available.

I hope this helps someone.

Cheers, Vann.

Well, I learn something new every day. I did not, until this post, realize that the British maintained their own conduit standard. Living in the United States, I'm familiar with the U.S. standard, and I know there's a metric standard; but now I know there was a British standard.

I dream, idly, of running into a Wadkin MZF bandsaw at some estate sale, at a price I can't turn down (preferably one that had been rebuilt by the previous owner a year or two before the estate sale - hey, if you're going to dream, do it right!):

but I'm too lazy to go out in pursuit of one - that is, I would not drive hundreds of miles to bring one home. Wadkin machines are more common than hen's teeth here in the U.S., but just barely so.

If I did, though, I confess that I would not attempt to track down correct conduit if I needed to rewire it.

By the way, your generosity in offering the fittings even though you're still in progress on machines is so typical of woodworkers worldwide. Good on you.

Hi Bill.

The British had standards for everything. Apart from the obvious BSW (British Standard Whitworth) and BSF (British Standard Fine) there were threads such as British Standard Cycle threads (for bikes); brass threads, gas threads (for gas pipes) and others that I don't recall off the top of my head.

And I like the way you dream...

Cheers, Vann.

I suppose the British Standard conduit was specially rated to retain the smoke from Lucas electrical systems better than other conduits

Digressing a bit: for some reason, lamp fittings in the U.S. still use some thread pitches unused by anyone else anywhere in any U.S. industry. It can get frustrating, if you're doing something that could be made right with a standard nut, except a standard nut won't fit.
