Thread: Machine Bench on castors
17/11/2016 12:49:50
Posted by Mark Whelan on 16/11/2016 10:43:08:

Hi Guys,

I about to be welding up a new workbench as a home for my new myford/drummond and westbury milling machines, and I was just having a debate with myself about putting the whole table on some castors for flexability in my limited space.

Neither machine is particularly heavy, but it still seems slightly odd in my head.

Anybody else have any horror/success stories?

Mark

I saw a steel bench pictured on here recently, where the person had built it with castors so it could be moved, but next to the castors on each corner he had also fitted a bolt and locknut, which could be screwed down to lift the castors off the ground, in order to locate the bench securely. You could also no doubt use these for machine levelling, if required. Seems like a logical solution.

Noting all this talk about MDF, OSB, chipboard and ply, it will be fascinating to see how the OP gets on with that, given his first post states he is 'welding up a new workbench'! wink

Couldn't find books in their menu, and when I typed in "books" or "engineering books" nothing came up either ?

It is in the right hand side menu, just before half way down, titled 'Engineering books and DVD's'.

So when exactly does a pipe become a tube?

In my interpretation, a tube is normally structural in some way, and not intended to carry any substance.

A pipe carries a substance - liquid, gas, air etc.

They are identical when they are a piece of pipe/tube of identical dimensions before they are put into use, they change definition according to their end use.

So i guess a tube of paint/toothpaste/gel/smarties is just using the term out of context? The word tubular describes a shape, i.e tube-like it doesn't covey a purpose. A pipe can be described to be tubular for example. Therefore they must be one and the same thing.

This is just like asking when a painting becomes a drawing. You're essentially doing the same thing with both, just using different mediums but they could be described as either. E.g surely an ink blot "drawing" has brush strokes painted onto it? Or Lucian Freud's life "drawings" are actually paintings? The only reasonable conclusion is they can be both.

You obviously have far more time on your hands than me, I was fast asleep at 01:10 wink.

This is now way off original topic, let's leave it here smiley.

I can answer 1)

It was probably made in China, and built down to a price, and not up to a quality.

Now I'm totally confused (what's new I hear you say). Do you mean these **LINK** - not normally referred to as "4 way"

Rod

I think the reference to 'Dickson' in the original post makes it clear.

And you will note that RDG (the parent of 'new' Myford) sloppily refers to them as 'Dixon' - grrr!

Possibly deliberate if they are 'Dickson'-style not 'Dickson'-make.

Neil

Good point......but still grates angry 2 !

I would go for rotagrip,I have found them very good & knowledgeable, for over 25 years,have bought items via post and visits

Rotagrip QCTP and holders are of course Bison.

It is said, but I don't know how much fact is behind this, that one make tool holder may not fit another tool post very well, and you should keep like for like.

The Lynam ones are supposed to be good, Bison aren't bad either. You can normally tell Bison by the engraved numbers on the lower face of the holder.

Plenty of hookey 'Dickson' stuff out there (or 'Dixon' even, that makes me cringe).

And to add, if you are going to change the motor, I would get that first, and make the sleeve to fit the new motor shaft/pulley bore. Don't assume if a motor is advertised with a 1/2" shaft, that is exactly what it will have!

This reminds me of a Hilka polisher I bought off the bay a couple of years ago.

It is based on a double ended bench grinder, and you take the grinding wheels of and slip an adaptor on the shaft with stepped tapered ends to take the polishing wheels.

The adaptor is secured with a grub screw, but the adaptor isn't an inteference fit, so the grub screw pushes it to one side. When you have two polishing mops turning at near on 3000rpm, it literally violently throws itself off the bench, it is so out of balance. I'm not suggesting you will have the same problem, but you will get my point, I am sure.

Ironically your nice Fobco cast iron pulleys will exaggerate any out of centre malarkey, as their extra mass over lightweight alloy ones will exacerbate any imbalance.

08/11/2016 18:05:40

As Brian says - with tube, diameter is normally external, bore is internal.

Also as he says, if the sleeve isn't near on an inteference fit (on both pulley and shaft), the grub screw (which should bear on the sleeve, as Brian says again, not through a hole to the shaft) will push the sleeve to one side, and put the pulley out of balance, inevitably causing vibration.

My tidy brain finds reducers like that a bodge anyway (no criticism of you, you bought it that way), why not just swop the pulley for one with the correct bore, such as below?

http://www.ebay.co.uk/itm/172382644885?_trksid=p2055119.m1438.l2649&var=471209915903&ssPageName=STRK%3AMEBIDX%3AIT

 

Note: I know that is 5/8 and you want 1/2", and you may not want the same diameter/number of pulleys, it just happened to be the one I selected, and they will bore you a blank to 1/2" of the size pulley block you choose.

 

In a week of what seems to be posting coincidences on here, I bought a Progress no 12 drill off the bay yesterday, and I have to replace both pulleys on that, so came across that supplier last evening!

Thread: C0 self centraling 3 jaw chuck.

Posted by Neil Wyatt on 07/11/2016 20:20:34:

As I said earlier the trick is "If you can't get them all even swap jaws 2 and 3 over and try again." Always leave No. 1 jaw in place.

Neil

Also noted Neil! smiley

Richard

 

Is no 1 jaw closer to the centre?

You may have just picked up no 2 and 3 jaws a scroll thread later than 1. Undo the chuck slowly whilst pulling on no 3 jaw, until no 3 comes out. Then continue to undo the chuck until no 2 comes out (sorry!). Then do the same until no 1 comes out.

Do the chuck up again whilst pressing no 1 jaw in. As soon as it catches no 1 so you can't pull it out again, insert no 2 whilst pushing on it, and turn the chuck to close it, until it catches no 2. Repeat for no 3 jaw. You should now have all three on the correct part of the scroll.

Funnily enough I was putting a 3 jaw Burnerd back together half an hour ago after cleaning the previous owner's cast iron dust out!

Your jaws should be numbered 1,2,3; as will be their slots in the chuck.

Insert jaw 1 into its slot, wind the chuck key until the scroll thread JUST catches it. Insert jaw 2, carry on rotating the chuck until the scroll catches that one, repeat for 3.

Job done smiley.

David,

Crammed garage? I know that feeling. What worked for me..... a few trips to the tip (recycling centre) and the scrapyard.

What are you going to build - anything exciting?

Phil H

Phil

I completed building my bench this evening, I can cram that with junk too now!

I am in the process of rebuilding some 1950/60's British steel framed racing (push)bikes, plus I do a bit of amateur gunsmithing, so will be threading barrels and things like that. smiley
