New T-nut?
Advert

Hello all,

Need help please.

I wish to use my T2 QC on my Warco BH600G, but not sure how to secure it to the top-slide.

Photos of how the original toolpost is secured on my Photobucket site

http://photobucket.com/albums/h322/Geoff_Halstead

in the Warco folder.

Do I use the existing T-nut with a new stud, or make a new one with stud?

As can be seen the existing stud had a flange that fastens down onto the top-slide

The Dixon has a sleeve down the centre with flange at the top, but not sure if I need to keep it in place or not.

Also shown are photos of how I used the space between the stand towers that has worked out perfectly.

Oh, the lathe has been raised 6" as when I had my Emco V10P with stand, I suffered back ache from having to bend over all the time to see what I was doing.

Easy to make a duckboard if needed.

Must say the Warco is a lot beefier compared with the Emco.

I have fitted a Newton Tesla VFD and what a pleasure it now is selecting speed.

All I need now is to fit a rev counter.

All suggestions/advise appreciated.

Cheers,

Geoff – Nearly all the snow melted

Sorry everyone, it should be Dickson not Dixon – Duh

Three score plus nine and a half years is my excuse, today at least.

After after further thought havee decided to make a new T-nut and stud

Hi Geoff

Read your first post, found you photos ( but find them a bit small for my threescore years and nearly nine eyes). I was going to suggest that you made another T-Nut and stud but then I see from your second post that you have already reached that decision. As usual I'm superflous!

Good luck!

Topslide T slot looks a bit on the slender side so it would be advisable to go for full engagement of Tee nut in both slots to reduce the chance of deforming the slide. My Dickson 2T and quality clone posts have a circular recess in the base which would let you use a threaded ring to lock the stud in place rather than simply tensioning up via the nut.

My posts also have a thru' hole for, presumably, an indexing pin. If you have vertical room consider making the aforementioned threaded collar stepped with a lower section diameter the same as the toolpost across flats dimension. This larger diameter could be drilled with suitable indexing holes so the post could be rapidly set back square to the axis for parting off if you need to work with it at an angle for access or other reasons. Thickness of around 6 mm, 1/4" should do fine. That task is on my the "get-a-roundtuit" list for my Smart & Brown 1024VSL. My top-slide normally lives at 25° angle off ready for screw-cutting so three index holes will do me just fine.

Hi Geoff,

OT but do you have any details/photos etc of how you did the conversion on your up and over door, have been thinking about something like that on one of my garage doors.

thanks

A quick look at 2 supplier's T2 QCTP don't show the 'sleeve'. On that 4-way there is a click stop so that you can rotate it on that lower disc and later return to the same tool and have a reasonable chance of getting back to the same position for repeat jobs (though not perhaps super accurate) . The QCTP doesn't need this so much as the block is mostly fixed and the holders change except for set over screwcutting.

I suggest you can get away without that it but think about how often you will spin the block and if returning to the same registration is reliable and necessary.

(BTW do you want to sell that 4-way block?)

Graeme,

I've put more photos up in another folder – Garage Door Conversion

I did the conversion in '07, and memory somewhat vague as to the precise process, but here goes.

BEWARE!

Whilst I was deciding how to go about it, I was in my local Jewsons and happened to mention my plan to one of the guys.

He looked at me, crooked his finger and took me outside to their scrap area where a complete Up&Over spring assembly was.

He pointed to hole through the spring shaft, on the RH side of the assembly, and said I MUST MUST MUST lock the assembly with something through the hole and resting against the swing arm tube – I used an R clip.

He then went on to tell me that one of his customers had just killed himself when he undid the arms that pivot at the spring and attach on the door, without locking the spring down.

Result was the whole spring unit flew apart taking him with it, to be found by his wife some time later!

FIRST THING TO DO!

LOCK the spring unit down!

Photos show where the hole in the shaft is, and the R clip in position. A nail would also work.

Down to the procedure:

I used 4 bolt/screw holed hinges.

I had space to get to the side of the door whilst it still worked as designed.

Measure up to position the top hinge so that the hinge part was clear and drilled the upper hole in the door channel, the hole large enough to pass the head of a wood screw through.

Ditto bottom hinge.

Both hinges then either bolted up to the door channel or to the wood door framework – don't remember.

Now it was time to get my nice neighbour & son involved.

They hung onto the door up as I locked the spring down and removed the two hinged arms and wire rope.

It was then a matter of manhandling the door, lining the hinges up so that all was free and drilling the hinge bottom holes into the channel section, wood frame & bolting/screwing up.

I used washers in the channel section I fixed the hinges to, to give more strength.

After about 9 months, I noticed that the door was sagging at its outer end so fitted a centre hinge and that seemed to stop the sag.

I couldn't believe how much space had been liberated, as now I could put stuff right up against the door where previously it just wasn't possible

SIDE DOOR

After about 6 months the need to keep the area in front of the door clear was nagging at me, so decided to put a door in!

Much thought went into this and eventually this was how I did it:

Mark out – then measure measure measure, then have a cuppa, measure again then call it a day and cogitate what/if I'd measured correctly or was approaching it properly – what can I say three score plus years takes its toll on the old grey matter.

Having decided all was correct, I braced the inside of the door to stop it collapsing when slicing through, but this proved unnecessary.

I also riveted the cross braces to the door skin for extra support, took a deep breath and went for it with ubiquitous angle grinder – how did we manage before?

Angle iron was used to close the ends off, hinges welded on and a jacking bolt added to the bottom of the larger section to stop the sag and to stop it flapping, with top end held to the wood frame by bolt & wing nut.

A suitable method of locking up either from inside or out added, and Bob's your Father's Brother.

Space in front of the door liberated!

What more can a guy want.

I did the same with the new carport door when I replaced the tarpaulin one.

This time, however, I used a plain Up&Over door without the spring mechanism, thanks to my new neighbour telling me that they where available, when I told him that I was measuring up to make a door,

Took me a while to track down a supplier in Brum.

It would have cost me more than £105 just for the material.

just neede a coat of paint.

!You MUST MUST MUST tie that spring down before you do anything!

Go for it!

Geoff,
I suggest you keep the t-nut, make a new post that is a close fit in the sleeve and threaded at he bottom to fit the nut. I don't see that the sleeve is necessary and you could make a thicker post. The current top clamp probably won't fit as it looks a larger thread than will fit the new post.
Not essential but to stop the nut moving when the clamp is released to rotate the block make a couple of grub screw holes in the nut to push it up into the T. It would be better, and not difficult to make a new nut so that you could make it with a shoulder to locate in the slot part.
It might be worth looking carefully to see if the spring detent can be used by making slots in the QCTP block to match the 4-way.

By the way that R clip in the spring looks like a disaster waiting to catch someone after you move/pass away. I would put a twenty foot rope through it and give it a yank from down the street..

Good pointer Bazyle, thanks!

Will attach a red note to the spring assembly with a red streamer ala aircraft practice.

Decided to make a new T nut and not use the sleeve, so that the stud can be thicker as you mentioned.

The QC is hardened, so won't be putting slots in it.

Not too worried about aligning, as I intend milling a new T-slot in the rear of the cross-slide and fitting another QC there, for parting & chamfering etc

Interesting to see that your 2 station toolpost has a flat base and no indexing pin hole. My 3 station ones, both Dickson and Rapid (high quality Italian made clone), have a circular recess around 1/4 inch deep by 1 1/2 inch (ish) diameter in the centre and indexing pin holes. This lack of central support has resulted in slight distortion of the mounting faces on the top-slides of my Smart & Brown 1024 VSL and Pratt & Whitney 12 x 30 model B lathes. The S&B has a plain top and the P&W a tee slot. Both are, ahem, "somewhat robustly made" but still not completely proof against the attentions of "Heave it up tight, real tight!" Harry along with his depressingly numerous fans and imitators.

Pity no one told ol' Harry that a thin card / stiff paper washer or alloy disk betwixt slide and post ensures ample holding power at quite modest tightening torque. Actually I'm somewhat surprised that a suitable alloy disk or three was not supplied as standard with the toolpost. The tool is, inevitably, considerably offset from the central clamping stud. Cutting forces put a twisting action on the toolpost so the greater the separation the greater the mechanical advantage and the more likely things are to shift. One reason why I'm ambivalent about QC systems.

Clive,

Thanks for reminding me about the card trick, something I had completely forgotten about.

My first use of a Dickson was with my V10P and was converted, hence fitting one on the BH600.

Bazyl,

i will be holding on to the 4-way for the time being, but will let you know if I change my mind.

Yes I have Paul, thanks.

Photocopied the whole series from my magazines.

That's where I found out about the extra T-slot.

Was going to do the clutch, but fitted the VFD instead, with absolutely no regret.

Don't know yet what other mods I will do, but one thing I must sort out is the oil weeping from the headstock oil sight glasses.

They loose all the oil over a 10 day period, but the previous owner did warn me about that, but haven't removed them yet to check why.

I will see how I get on with the lathe before making any further changes.

T-nut done!

It's the full length of the topslide T-slot, as suggested by Clive Foster.

The Boxford shaper performed its magic, with smoking chips flying of the work piece, so I will need to make some deflector/s to stop them and get them to fall onto the tray. Must think up a universal design to be able to use the deflector/s on the milling machines, lathe and drilling machine.

I now, however, need more advise please, with regards the Toolpost post/stud.

Do I do as the original and have it screw into the new T-nut, or can I just weld it in?

Plug weld on the underside and maybe chamfer the top and weld there as well, don't know.

I will not use the sleeve that came with the Toolpost, so can make a thicker post/stud.

Welding will save having to use tap and die.

Clive,

I'm struggling to visualize your description for indexing the Dickson, so would appreciate a sketch or whatever please.

Geoff – Burger & chips time.

It's done!

Photos added.

The last time I did anything on a lathe was in the mid 1980s, and oh man has it been an awakening.

Things that have been brought home with a wallop;

1) Everything is taking 3-4 times longer than expected,

2) Silly mistakes due to lack of practice, like me winding the saddle in the wrong direction, as I've posted about,

3) Attempting to use a totally wrong method to put a thread on the Toolpost stud,

4) Having to measure and check 3-5 times before putting cutting tool to metal or wood,

5) It is still, however, so so satisfying to do something useful, and have friends marvel at it (The Toolpost hold down nut in question)

6) I'm not going to finish a quarter of the projects I have planned, and that is a bummer!

7) With luck and perseverance, however, things should improve from now on as my previous experience comes to the fore.

Must admit that the BH600G is so much better at removing metal compared to the Emco V10P I had, and the VFD means that I will no longer make a clutch for it.

These last weeks have brought back memories of me when I first started to use the Emco, and not knowing what I was doing.

Parting off is one thing that has changed dramatically, and now no longer the nightmare it was.

With the QC fitted, I may postpone making a rear Toolpost, and concentrate on getting my drawers organized and labelled [tools drawers that is ].

Right now I have absolutely no idea which one holds what, and I'm sick and tired of having to look through each bl**dy one to find anything.

Geoff – A happy bunny.

Forgot to add that I will be placing a card washer under the QC, and will probably have to take a scrim off of the hold down nut to get the handle into a more convenient position.

8) I drilled and tapped the hold down nut for the handle, even thought I told myself beforehand to wait until it was fitted – DUH!

New handle fitted and a 'key' made.

Setting the QC up, memories came flooding back as to why I soon bought one for my first lathe!

The total ease in setting tool bit height and swapping tool holders the reason.

I soon, however, found that a proper 'key' was preferable to using a combination spanner to swap tool holders.

The correct 3/8th keys on eBay are an eye watering £24.00, so decided I could make one, so hunted for a solution, but not knowing what size of cap head set screw has a 3/8th hex, decided to use a box spanner instead, with suitable handle fitted.

The DIY 'key' works fine as is, but will give it time to see how I get on with it.

I did make an attempt at an indexing base for the QC, but although my first try proved the concept, my lack of precision at machining at present means that it's headed for the 'Re-use' bin. Well it has been 30 odd years since using a lathe and my first using a shaper.

Photos uploaded. Still cannot find a way of including photos with the post using my iPad.

After hefting the 4-jaw chuck on and off of the spindle a few times, some sort of hoist to handle it is now top of my project list, as changing chucks will soon become a chore.

Thinking of using a length of Unistrut channel, with open end facing down, with a trolley running on the leg inturned uprights (if that makes sense), with block and tackle attached, however, I would appreciate any ideas please. Photos will follow.

Geoff – Thoroughly enjoying the warmth and sunshine. At last says I!

If it's the original iPad [now stuck on iOS v5], I don't think you ever will.

Thanks Michael.

iPad 3 with iOS6, so will investigate more.

On the insert photo page, I select one, click the OK button, then after a moment I'm thrown back into the message being typed, without the photo being inserted

Must try the procedure on the MacBook.
