What Did You Do Today (2017)

[HopperParticipant @hopper]

I mounted and tested the 4 jaw chuck I had converted from Hercus to Myford (see above 2 days ago). There was a visible wobble, and TIR on the front face was at least 10 thou, so I'll have to call the project a failure. For comparison, I tested my direct mount (no backplate) 4 jaw on the Hercus: perfect, with undetectable runout on the face. I can always reclaim the chuck by chucking it in my Chinese 8" 4 jaw and bore away my Myford threaded sleeve. I suppose it was a big ask to get a precision result with such a project.

I think you would do better to make up a new sleeve, press it into position, with Loctite and perhaps a dowel pin or two on the join line, then bore the final hole in the sleeve and screw cut it with the chuck held on the faceplate dead true and centred etc. Or you could get a Myford sized backing plate, mount it on your spindle and machine it in position to fit the Hercus chuck.

[Simon CollierParticipant @simoncollier74340]

I reckon you are right, Hopper. That would be the only way to get close to an acceptable result. The problem of measuring a female thread and register remains however, without a male test piece. I suppose I could first make a replica of the spindle nose. You can buy such a thing from RDG too.

Hi All,

This morning I modified the silencer for my aero engine (FIREFLY 46).

I bought the basic silencer from just engines. All it is is just a hollow chamber, no baffle plate.

There website shows you how to make a super quiet silencer, which is quite a simple procedure.

All it involves is is inserting a short length of alloy tube shouldered at one end and recessed at the other to accept a baffle. The baffle I have made is in two parts and joined together with a self tapper. The size of the holes can be adjusted by rotating the upper plate. I also drilled the end of the silencer and inserted a shouldered and threaded bush. The external nut now just acts as a lock nut.

Not tested yet but my guess is it will be ok. geoff

Simon,

Like you said, bore the sleeve back out.

Sell it on and buy yourself the chuck that suits your lathe. It's been stated previously Loctite is used on aircraft. It was used by Nasa, it's used in Formula One and I use it a couple time a week in my day job but there is no way I would stand in front of a chuck spinning at 1400 RPM that's been glued together.

Maybe I'm just old fashioned but I like the way chuck manufacturers design their chucks.

Steve.

[ChrisHParticipant @chrish]

Simon. When I machined up a backplate for a new 4 jaw chuck I first made a dummy spigot test piece of the lathe nose. Luckily, I had a collet chuck which screws on the lathe nose to test the test piece before I called it done. Then I held the new backplate in the old 3 jaw and machined the back of the backplate, bored it and screwed threaded it to suit the test piece. Then I reversed the backplate and screwed it direct onto the lathe nose to machine up the mating flange complete, which ensured concentricity with the lathe nose. I machined up t'other end of the test piece to accept a M2 morse taper arbor, loctited it into the test piece, and used that in the rotary table to set up the backplate to drill the mounting holes. All I can say is the method worked well for me, and it has left me with a handy stub piece for the rotary table so as I can now transfer chucks from the lathe to the mill and back again without disturbing the work or loosing concentricity.

HTPs.

I finished changing all the incandescent lights in he entire house over to LED bulbs. It makes a world of difference; especially in the shop. Now there is no need to turn on additional light to read dials and measurements. In doing so I also replaced the circular fluorescent articulating light over my Speed 10 with an articulating light and 60W LED, WOW! Beautiful crystal clear light. Most bulbs are 60W which I purchased last week when they went on sale in a local store for 40% off.

[modeng2000Participant @modeng2000]

Bill, do you mean 60W equivalent LED?

[MuzzerParticipant @muzzer]

I have 60W LED dual battens. They are 6' long and 6000 lumens. Excellent lighting, although as noted previously, they are very similar to a 58W fluorescent strip in that regard (lumens per W).

I suspect Bill means 60W equivalent, which would be 9-10W consumption and around £3 each.

Hi All

A couple of years ago I bought a Chinese made 3-jaw for my S7b.

The TIR was about 0.005" and I accepted this by putting the chuch

on a shelf and using a Griptru.

Yesterday I took the chinese chuck to pieces and, after cleaning it I

put the back-plate on the spindle and took off 0.002" from the register diam.

Put the chuck together and just nipped the bolts holding th chuck to

the backplate.

Lo and behold – a gentle tap with a small plastic hammer and the

TIR had dropped to 0.020".

I've never done anything like that before and am very proud of

myself.

As I live with a friend who is epileptic we have only LED lighting.

General light in the w/s is a 4' Led Tube with 10W E.S. in reflector

fittings over lathe and bench.

Over mill spindle there are two 21 LED fittings in front of and behind the spindle.

And at 84 I have no problem seeing anything.

The eternal diatribe against Myfords means nothing.

If you want a larger spindle bore then buy a larger lathe;

my lathe has "Made in Britain" on it and it does all I want.

Plus, I lifted the phone today and bought some spares.

So – everyone to their choice and do not knock the other

bloke because he has something different.

You have your lathe – BUT- when the time comes mine

will still be worth quite a few pennies.

And having tried a few other lathes including the chipmaster

(my favourite) I still prefer mine.

The pleasure it gives me is incredible and that is all that matters.

So, into the shop make the necessary adaptors and put a diamond

disc onto my bench grinder; then mill a piece of

cast iron to make a rear tool holder to take a QCTP.

Best wishes everyone and enjoy whatever lathe you use.

Richard.

[Neil WyattModerator @neilwyatt]

Very happy with these from Toolstation (typing by the light of one now) two for £3.48!

http://www.toolstation.com/shop/Lighting/d220/LED+GLS+Lamps/sd3382/LED+GLS+Lamp/p22449

Gradually replacing CFLs as they fail in three-lamp luminaires with LED candle lamps at about £2.50 the pair!

Oh, Richard. Tir 0.005" going to 0.020" And you were happy? I hope it was a typo.

[richard 2Participant @richard2]

Hi BobH

Yes, typo it is and I thought I had checked!

0.002" it is.

Do you think that is acceptable?

Thanks.

Richard.

My visit to the metal monger, found a depth mic and a rare oil can

Very nice too.

Brian

[Speedy Builder5Participant @speedybuilder5]

Richard. I would check the runout over the range of the capacity of the chuck, say 3/8 " diameter, 1.5", and 3". If runout is about the same, I would accept it, but I bet others would disagree.

Nice oiler, we get quite a lot of Valvespout cans but usually the finish is very poor. Did have 3 brand new conical ones recently which are more common, all went to the USA. Sometimes one finds the top spouts on other cans as they are so good but of no value then.

Cheers, Martin

[Neil WyattModerator @neilwyatt]

I had a conical one for dabbing the moving bits of Southam, but I left it at the Derby track

Given the lifespan of the LEDs, the superb quality of the emitted light and the reduced electric consumption I believe it was money well spent. I am now tempted to follow your example and consider the cost of replacing the 6 X 4 ft fluorescent ceiling fixtures remaining in the house.

You are bang on with the price of the 60 W Equiv bulbs. The sale price was $4.99 CAD which at today's rate equates to 3.03 pounds sterling.

Abandoned workshop and put together (I don’t like “build” ) my new PC. It’s a bit OTT but should do the job for the conceivable future.

Full tower case.

Gigabyte Z170 Gaming K3 EU main board

AeroCool 750W bronze PSU

Intel Skylake Core i7 6700k CPU

Samsung 850 EVO 1TB M.2 SSD

Corsair Vengeance 32GB RAM 3000MHz

Blu-Ray DVD RW

AMD FirePro 7000 Graphics card

BenQ Zowie XL 2730 hi-res monitor

2TB HDD from my old PC.

 

Windows 10 with all files and apps ported over to new SSD drive even though the eggspurts say it can’t be done.

Together with a new BT Smart Hub 6 and a pair of TP-Link 1200Mbps Homeplugs the whole shebang goes like stink. Google Earth is always a good test providing broadband speed is good (ours is approx 52 Mbps) – dropping down to street view and jogging down a road I am getting instant refresh. Youtube HD vids run like a dream.

Well pleased with today’s efforts but I will not pretend that the jiggery pockery getting Windows 10 from the HDD to the M.2 SSD was without problems. Never mind, all seems to be jogging along nicely at the mo! Back in the workshop tomorrow!

Rik

Today I bodged up an M44 spanner for a mate (60.6mm AF).
I stamped it '44' in case he gets it mixed up with any similar spanners in his box

Not wanting to start a Mac/ pc war, machines like this are dinosaurs, plenty of laptops or macbooks/iMacs that will do the job these days and for gaming PlayStation or Xbox for £200.

I also went through this pc building process many years ago before I saw the light……..

[Cornish JackParticipant @cornishjack]

Rik – fascinating spec. and while Howi is correct in the availability of high power machines, there is great satisfaction in 'rolling your own'. What did strike me was the difference in your machine and my first – a TIKO (remember them?) 386 (basic, no co-pro), with a 40Mb(note the 'M&#39 hard drive and 4 Mbs RAM. Dos 3.2 (still got the floppies somewhere) and Windows 3. Dual floppy drive 3.5 and 5.25 and it cost …£1240.00!!! I well remember the sweaty, nervous session of upgrading with a co-pro and, later, new RAM!! Many self-builds later and nowadays it's much simpler to buy old office cast-offs.
