Thread: Older/cheaper lathes

Page 2, and still no mention of the most important bit of the age old question of 'what lathe to buy' - you still haven't stated your budget.

I use a Parweld XR935H.

Once you have gone to an auto darkening helmet, you will never go back to a manual flip one, and your eyes will thank you!

Without drawing it up in CAD your adapter sound awfully close to #13 Jarno taper.

There are three different bush sizes referred to in this thread, which one are you referring to? wink

Here's a Teasmade on Amazon UK, genuine Swan and a lot cheaper then 300E - buy it before the channel becomes and impassable barrier!

Isn't that straying into politics? wink

Thread: "Vintage" CNC

And in turn, I started my apprenticeship with Marconi at New Street in Chelmsford in 1969, I remember the black magic of the CNC machines there.

Strange how small things can steer your entire life.

So my late entry into Model Engineering after retiring was due to the Kaiser invading France via Belgium in 1914 in order to defeat the French Army before turning on his real target, the slow moving Russians, who were supporting fellow Slavs seeking independence from Germany's ally, the Austro-Hungarian empire. Actually, the real reason for Germany starting a war was internal: the ruling class wished to undermine the Socialists who were challenging their authority. As Belgium's independence was guaranteed by Britain in a Treaty signed in 1839, it triggered a chain of events such that I now own a Chinese lathe ...

Welcome back Ketan, and sorry you have brought an unwelcome stowaway back with you!

Is that supply of just chucks, or other interesting stuff? wink

Thread: Get on yer bike

For £60, you aren't going to get much.

It probably feels horrible to pedal, won't be stable, and won't be good for you ergonomically.

This is probably one of the best half decent budget exercise bikes to go for, that isn't crap:

It is totally impossible to put any sort of meaningful value on the machines, without clear photographs.

One man's 'as new' Myford is another man's boat anchor.

The only odd thing about it was the material source - there's no reason why that couldn't have been made from roundstock.

He made it from two nuts, because that was what he was asked to do, per the messaging in the 'WHY' bit at the end of the video.

Beautiful workmanship, particularly considering the humble source materials, which I expect was the whole raison d'etre.

Thread: Progress No2 GS Pillar Drill
24/01/2019 18:14:10

First thing I would do with that chuck, bearing in mind it is on a MT, is to set it up appropriately to alleviate damage to the quill, so the chuck is facing upwards, jaws fully retracted, and using a brass packing piece in between, take the aforementioned 4lb lump hammer, and give it one full force crack with the hammer to drive the chuck home in the quill.

I kid you not, that may apply enough force to just crack the taper free, so you can use a MT extractor.

I would also try a taper extractor, and as suggested above, machine it so it has a shallower taper.

If that doesn't work, what I would try then is to make two identical wedges, and machine them thin enough so you can apply one from either side, grease them well, and if you have a big enough vice, don't hit the wedges, but squeeze them in the vice, so you apply pressure rather than force, and it is evenly from either side.

I have got some MT shanks apart that have also been together for years, you just have to work out non destructive ways to do it, whilst applying the most effective force.

Are you using the tool slide or carriage wheel to advance the cuts?

I note you have been playing with the gib strips wink

Try locking down whichever axis you aren't using to see what effect that has - if you are advancing with the tool slide, lock the carriage, if you can, and vice versa.

Also try winding on your next depth of cut, and then locking the cross slide before advancing the cut.

Just takes some of the variables out of the equation.

Thread: Quick change tool holders

You probably can get 16mm tools in and achieve work centre (although I don't think that is what Boxford ever intended), but you will need the deepest tool holders.

The deeper the holder, the further you can lower the bottom of the cutting tool.

The Rotagrip/Bison ones are 35 or 44mm height.

The OEM ones are 38 or 44mm height.

I have probably around 40 tool holders, a mixture of all four types.

The platform the cutting tool sits on is around 5mm lower on the 44mm height tool holders than on the 38mm ones.

What are the RDG ones? Dunno, and there is no helpful information on their website.

Unless you can persuade someone at RDG to measure the overall height of their two types of toolholder, and the height of the tool platform off the base, I would not take a chance on them.

Don't get sidetracked by metric or imperial, as far as I know all the Dickson type QCTP and holders are metric.

I suspect your toolholders are TO/SO, which ties in with the markings on the toolpost.

Is yours a 'Rapid' marked toolpost? Boxford fitted these to many of their X10 lathes.

Can you measure the thickness under the part of the toolholder beneath where the cutting tool sits?

I suspect it is 10mm, +/- a bit.

Last question, and the most important one, do the toolholders you have sit the cutting tool tip at the correct centre height?

Hi guys, this may have been answered, but my tool post (on my Boxford 10-20sts) is stamped Boxford S0/B PD My tool holders have an opening of 19mm, 3 are metric, my parting holder is definitely imperial, (all the bolts are and it is taller than the metric holders) I'm not sure what size holders to buy. I contacted RDG, sadly the sales guy sounded uninterested/ bored
and told me he'd send me an email of their T51 holder. Email almost instantly arrived, with a "high quality CAD" attachment, which turned out to be a top elevation hand drawn (what we used to refer to as "fag packet drawing" of a tool holder, no height supplied that almost, but did not match mine. The CAD reference at least gave me my laugh for the day. I read with eager interest in this thread that T00 is the same as S00, and wondered where to get them, and what if anything /B PD referred to?
Apologies if this has been answered in another thread, best regards to all, Mark.

If you have an SO fitting, which should be correct for an X10 series Boxford, your toolholders should be 73mm long.

And to edit and add a couple of things, firstly the Rotagrip/Bison equivalent of SO fit is TO.

You will also see there are TO and T1 holders, plus TIX.

The only difference is the height of the tool holder, and that dictates the tool height, since the floor of the TO and T1 holders is a different thickness.

For SO/TO, your toolpost should be 73x73x51mm high.

If your holders are 73mm wide and 35mm high, they are TO/SO holders.

If they are 73mm long and 44mm high, they are T1/S1 (or T1X) holders.

The two different in height holders have a different holder tool slot base height, and thus dictate the centre height of the cutting tool.

If you are really lucky and have Bison tool holders, that is easy, standard tool holders should be engraved 4494-62 or 4494-62N on the front.

4494-62 are 44mm high holders, 4494-62N are 35mm high.

 

Once you get your head round the way these are dimensioned, it is easy, honest!

I bet the C130 had a bit of time amended on its fatigue life!

Fairly soft landing for a Fat Albert, that's what they are built for! A hook would have probably stressed the airframe more.
