Thread: Progress No1 Pillar Drill.

Several places sell multi step pulleys so you should be able to buy something suitable. I think you may have to make the other bits.

Thread: is a belt sander any good for hss tooling

The nice thing for me about using a belt sander is that you get a flat grind.

These look pretty good for the money. There are very similar looking models for a bit less of the folding stuff.

Belt & Disc Sander

27/07/2021 18:58:34

I’ve been using a Record Power Belt & Disc sander for sharpening HSS tools for many years. I normally use 80g Alox for sharpening but you can go to 120g for a more polished edge if you want. Belts last quite a while and aren’t too expensive. Belts for my machine are 6” wide but I sometimes split them into three 2” belts (easily done) for tool sharpening.

Thread: Centre Drill Leaves a “Pip” - Sometimes

Most of my spotting drills are quite long so to increase rigidity for lathe use I cut one of mine down a bit.

If small drills are wandering without centre drilling first then either the drill, or technique, are in need of revision.

Andrew

Pray tell us what is this wonderful technique which guarantees a small drill will not wander on touching the work piece surface.

Thanks,

Tony

yes

Thread: Live Centre Bearings

I need to replace the 6001Z bearings in my Live centre. Options are Dunlop or Nachi and standard or C3 clearance. Any suggestions?

Spotting drills were never mentioned in the old books I used to read on engineering although they were not that old when I read them. Centre drills were the standard method of starting a drill as taught to me in metalwork at school then tech college and the factory training school. As NC and later CNC were quite new when I started work, that is it was barely 20 years old I suspect a lot of tooling has been created to meet the needs of automated machining and so was not on the curriculum when many of us were taught workshop methods. We should not be shy of embracing new things but if your current technique works there is no need to buy new tooling for the sake of it. Being aware of new options can as Andrew mentions save time and money in commercial work although pottering about in our own workshops for fun, time often doesn’t matter too much.

Mike

I was never told about spotting drills either. I started using them about twelve years ago when I was disappointed with the results from using a centre drill. I’ve tried to tell others but some just come out with the old “I’ve always done it this way” remark about centre drills so I let them get on with it.

I’ve watched quite a few programmes involving the movement of very large bits of machinery. In many cases it was done with electric prime movers because of their compact size and tremendous power. Ironically they were fed by Diesel engines. I’m guessing size for size electric motors are far more powerful than ICE?

The sun doesn't always shine.

Howard

I think you’ll find it does. It’s been shining for millions of years and has millions to go before it goes out. wink 2

Storage of all that power is the issue and there are lots of companies addressing it.

Just one

Another solution put forward is a fully connected power network, because as the sun shines all the time it will be providing energy somewhere on our ball. Politics though means this is highly unlikely to ever happen.

I’m sure we can find solutions if those with the imagination work at it.

Thread: Chuck fitting
20/07/2021 21:27:26

All my chucks, 4” 3JSC, 4” FJI, 5” FJI and ER32 collet all have the same bolt hole centres.

Some of the studs arrived today so I tried it out using the existing holes and some flange nuts and it seemed quite secure. Once I can see what clearance I have I may make some top hat washers for the existing holes and see how that goes.

Another Antex user. I have a couple of the small ones for little electronics jobs. A guy I used to work with though liked those huge red pistol types. I couldn’t get on with it but he liked the instant hear feature.

Thread: Chuck fitting

Spacing the new holes like that was my first thought but it doesn’t matter, I’ll still have the choice no matter where the holes are.

18/07/2021 11:15:51

After some thought I think I’d prefer to re-drill three new holes in the flange if I can. I will test it with a new bit soon. One concern for me was bolt spacing with the flange in situ. I do however have a collet Chuck with threaded through holes so I could clamp this in place and use it as a guide with some threaded guides in the holes. I did also think to space the new holes equidistant with the old but I’m not sure there’s any advantage in this. If I can drill the flange I plan on using hi tensile socket set screws and flanged nuts. My thinking with all of this is that provided the threads are kept clean I should be able to spin the nuts on and off most of the way with tools, just resorting to a spanner for final tightening.

Thread: 75mm x 2000mm Belt Linisher Build Thread

I find threading anything over 8mm a bit of a chore Martin. The last thread I cut was M6 and the finish on steel was rubbish so I bought a new Die. Looking good so far, keep going. wink
