To the Beefans and Beekeepers - how about signing this?

Thread: Qualters &Smith QDM750 pillar drill - back gear.
28/03/2015 23:38:38

Might have solved the mystery myself.

I have enlarged the drawings in the manual and can now see that the hex-headed screw is not intended to engage with the spindle.

Since this drill revs to 3000/min, I now think the screw is a mass balance.

My recently acquired specimen of the drill in the title has a lift-pin to engage/release the spindle gear.

Diametrically opposite the lift pin there is a short 3/8BSW hex-headed screw that seems to also engage in the spindle gear.

I have the manual, but there is no mention of the screw.

Can anyone enlighten me as to its purpose and use?

Incidentally, it is an excellent piece of kit.

Thread: Chipmaster question
27/02/2015 19:30:17

I posted this on the Yahoo user group, but no response as yet.

Can anyone define the crossfeed screw for me in terms of diameter, thread form, pitch, hand and length?

The lathe is Imperial.

I want to replace the screw soon but cannot strip the lathe at the moment.

Thanks in advance,

Charles

You mean I could have bought them cheaper?

What about a garage tool trolley / cabinet - storage and shiftability.

Reassembled a Union 1/2" pillar drill that I collected yesterday.

Now I need to source a new drive belt - I don't suppose anyone knows the size?

Is that by any chance a Relum Tornado?

If it is, I may be able to help.

Thread: Base for a new machine shop aka "shed"!
20/02/2014 00:33:39

I laid a 5" concrete floor slab over 50mm of Kingspan. Laid quarry tiles over the concrete and waterproof grouted overall.

Once the machinery was through the door, I welded up a door frame of 75 x 30mm box section and installed it with brackets rawlbolted to the structure (so the machines may be removed to pay for my first 2 days of residential care).

This was in 2004 and the Chipmaster lathe and Boxford mill are happy at home.

Thread: Ring making ideas
25/08/2012 23:59:58

Thanks to all, but I see that my original question has been "lost in space".

I have already tried bending on a former, hot, cold and last Tuesday.

Loved the "back country machines" in the Youtube clips!

There is no time for me to make a ring roller - but the tool illustrated would certainly do the job!

Probably my cheapest, easiest and most repeatable for trials purposes will be to bend semicircles in a pipe bender and then cut & weld to suit.

Again, thanks to all, especially Springbok who suggested I ask about my 250 and 350mm rings on a jewellery forum.

Hippo nose rings perhaps?

If you still need variator mounting feet, try here: **LINK**

For all the oils for my Chippy, I went to: **LINK**

I have found the RDG QC toolpost completely adequate for my requirements.

Thread: Ring making ideas
23/08/2012 15:14:55

Hello all.

I need to make a few 250mm and 350mm rings from 8mm MS round bar as trial material for a project.

I have tried bending forks on the anvil, wrapping a coil round a former but the results are not sufficiently repeatable.

A ring roller is the obvious solution but I cannot make the investment before I know the project is feasible.

Has anyone used a pipe or conduit bender to make complete circles?

Thread: Tearing hair out with disc sander

Thanks to all who replied.
 
Things have moved on and I have decided to mount the disc on a short shaft and provide the motor with a pulley for belt drive.
 
I happen to have a pair of 3-groove V-belt pulleys lying around so limited speed control will be available.
 
Picador rules OK!

Great stuff,
 
A lot to think about.
 
Many thanks - I will revert with more data.

I happened upon a 1/2 hp 240V electric motor and decided it would form the power source for a disc sander.
 
A 12" alloy disc was sourced, a shaft bush was inserted in the boss of the disc and there was .060" runout on the disc surface.
 
On checking on the surface plate, the disc is flat within .008" and the mounting hole is concentric within .008".
 
The motor shaft is 12.5mm (sorry to mix conventions) and runout is less than .001"
 
One issue is that the motor shaft has a 2" overhang from the mounting surface plus a threaded end and I had to make the shaft bush with an internal shoulder to square itself on a step in the shaft. a retaining nut and penny washer was used to retain the disc and tension the shaft in the shaft bush. The bush and the shoulder show no discernable runout.
 
The disc mounting hole is therefore, probably not square to the disc surface.
 
My lathe is a 10" Chipmaster and obviously cannot swing the disc.
 
Other tools are a Boxford mill and a pretty solid pillar drill.
 
Any suggestions how to proceed?
 
Thanks in advance for any thoughts.

Thread: Torx screws

I keep losing the tiny Torx screws from my insert tools.
 
Does anyone have a source for bulk spares?
 
Thanks,

Thread: Safety

My school chemistry teacher was demonstrating distillation or some other process one day (1961) and he left a rubber bung sealing the boiling flask.
 
Predictably it exploded creating a very loud bang and a mass of glass shrapnel.
By some miracle, only the teacher himself was injured (a small cut to his upper lip) and the class quickly recovered from the shock.
 
One week later, the lesson was repeated. Same class, same teacher - and he did it again!
 
Nobody sued, nobody even complained.

I use a Maktec (cheapo Makita) 14" abrasive chop saw. Use it outdoors and with ear defenders!
 
It cost me about £70 4 years ago. Discs can be had for about £3 a pop.
 
There's one on Ebay for £60 but you will need a 110V transformer.

Just to echo Major Disaster's comments on Hallett OIls.
 
They quote alternatives to most if not all of the oils & lubricants needed for our (in my case) elderly machines.

And I too am only a satisfied customer with no axe to grind and nothing to gain from this recommendation.
