Thread: Rotary Table Chucks
15/12/2020 19:05:47

Earlier this month, in this thread, I asked the forum for opinions on Zither lathe chucks.

I had no specific replies but nevertheless decided to take the plunge and buy one from Arc.

I chose the 80mm, 4jaw, self centering chuck which Arc currently have on offer at £73.

Have to say I'm pleased with the purchase.

A few grumbles when it came out of the box, sharp corners which need minor fettling and careless number punching around the jaws slots but otherwise initial impressions were good.

I turned the register on the backplate to a precise fit in the chuck recess, drilled and tapped for the front mounting bolts, assembled the two and screwed it back onto the spindle nose.

With a short length of 5/8" silver held in the chuck I was ready for the real test of this chuck. For me to be happy, with the lathe running the bar would have to appear, APPEAR, to be running true. Well it most certainly did visually run true.

I then clocked it with a D.T.I. and it ran out by less than 1/2 thou which for a £70 chuck I would say is very good. Tested it with other diameters with the same result.

Overall at least an 8/10 chuck especially at the price and a big thumbs up for arc again, I have never been disappointed with any purchase from them.

Hi Andrew,

Thanks for your reply.

Just had another look at the chronos "soba" chuck, listed as soba but in the details it is classed as unbranded which would seem to confirm what you said.

Had a look at the Arc chucks. I notice they have an 80mm 4 jaw s.c. which is on offer. It also has the front mounting which is what I need. Looks good value and is probably good enough for my needs. Made by ZITHER?

I have bought a lot of stuff from Arc, never been disappointed yet.

ZITHER chucks anyone, opinions?

I've enjoyed reading this thread. every post has had something of interest.

Just bought the Axminster 110mm table and initial impressions are certainly good.

A few glitches but nothing that couldn't be sorted quickly.

Have spent the day making a sub table and mounting a 4 jaw chuck on it.

I would like a 3 jaw as well for the same sub table.

So a question. I notice that chronos are doing a soba 100mm chuck with front mounting for a penny under £70.

The price is right but what's the quality like?

Has anyone any experience of this chuck or soba chucks generally?

All the tiny bits really do test your patience but glad I made it as I will be using in the near future

If anyone else is planning to make it, do have some valium on hand!!!

Nice work, Kevin,

I like the boiler a lot, I'm currently making one myself.

Are there any details about the boiler you could share i.e. construction methods for both the boiler and stand, type of paint used etc.

Hi All

I have been making the mini bender for 1/16" pipes.

A few more errors I believe!!

Nothing to serious but here we go.....

I think the lever should be 3/16" square stock and not 1/4" as shown. No size given in issue 64 but if you check the fulcrum it has a 3/16" long spigot.

The 0.094" size on the former is wrong, should be 0.0625". the 0.094 is correct in issue 64

There is a size missing for the position of the left hand hand hole in the base, i.e. from the end of the plate to the centre line of the hole. I guessed 1/4" would be ok. Size also missing in issue 64.

Yes Harry that's right issue 297

Do have a look at the Derek brown thread.

There are some issues with the article in 297 which are discussed in the thread

Geoff

Steve there is a thread on here for pipe bender I have made.

Search for Derek browns pipe bender MEW297 and you will find it.

There are numerous drawings in the thread but a read of the article would help if you intend to make it.

No prizes for guessing what it is?

Your wife is not going to be happy with the sink taking 6 hours to drain through such a small u-bend laugh

Oh yes Bazyle!

My wife does complain a lot.

Only yesterday the handle came of a pan lid.

I was charged with fixing it right away, which I did.

Of course she complained, not good enough she said.

I'm really pleased that I made the pipe bender in the last MEW.

Not that difficult to make and gives really neat bends.

Made some 1/8" formers yesterday and then made my first component part.

No prizes for guessing what it is?

Great finish Doc, well done, I love the parade of parts, very regimental not a part out of place.

Well you've set the standard now, no going backlaugh.

I suspect you will have no problem maintaining it.

Thread: fabrication

Hi, J, David

Thanks for the replies.

I considered soft solder David. I have been experimenting on some brass joints with bernz o matic silver bearing lead free solder and templers telux soldering flux and you do get an incredibly strong joint. It may still be a way forward

Jason I was delighted that you concur with my gut feeling about JB weld. I shall proceed with confidence.

Thanks again Geoff

16/10/2020 16:50:56

Hi All,

I was doodling earlier today, planning a fabricated standard for a simple oscillator.

Could I invite comments on the rough sketches below.

I would like use JB weld for all the joints preferably without any other mechanical fixings.

The standard will be around 80-90mm high.

My plan would be to do all machining after it is fully assembled and cured, i.e machining the face and drill/reaming the crankshaft and trunnion holes.

I would add fillets to all the joints with the idea of giving the final appearance of a casting.

I have limited experience of using JB weld, my gut feeling is this would be a strong structure, but I do invite comments, thank you.

"Is there any advantage in spacing the formers off from the base plate?"

Well I have to say I was puzzled as to why there is a spacer under the fixed former.

The "rolling former" has no spacer and is therefore only aligned with the fixed one when there is pipe in between them. In my photo in previous post a piece of silver steel is aligning the two formers.

i can only assume that the rolling former needs to self align and perhaps that is why there is a spacer under the fixed roller to give some clearance?

just my thoughts

11/10/2020 16:50:44

I've had some fun making one of these.

Currently making a small pot boiler and will be using some 3/16" pipe to couple the hand pump to the clack valve.

So I decided to have a go at making one.

I drilled the baseplate with all the holes but so far have only made formers etc. for 3/16" pipe.

Like I said it's been fun, enjoyed making it, came together well.

No pipe at the moment need to order some.

Anyone else "havin a go"

I think you would to cut a channel for the exhaust port. If you try to distort the cladding when you tighten up the exhaust the cladding will just buckle.

Is the cladding aluminium? If yes I am left wondering why the anodising did not crack when you formed the curve. What gauge is it, can you put a Mike on it to find out, I'd be interested to know.

Also can you give more details about how you formed the curve. Was it as simple as you make sound to get such a neat curve, no clamping involved?

Thanks geoff.

Great work doc, once again I admire your attention to detail
