Thread: Lacquer or light oil?

Renaissance wax polish would protect it.

I agree. This is what the museums use themselves to protect all kinds of things. Even ancient artifacts. It's good stuff. 👍

Thread: Clarke CL251mh Milling Attachment Wiring Help
18/08/2019 09:24:25

I have one of these. I can tell you with 100% confidence it is a DC Motor. I know because it confused me too. The problem is the little sticker on the milling head describes input voltage to the lathe and not the milling head motor. 😒

You will need a DC speed controller to get it running.

Thread: First Lathe
08/08/2019 10:03:23

Personally I would go secondhand. Your budget gets you into Harrison, Colchester, Boxford territory and while you might not get every feature you want the overall quality of the lathe will be superior. I can say that as someone who has owned both British and Chinese lathes.

Thread: Good inserts For (t6 i think) aluminium
02/08/2019 20:17:23

I agree with the above. The CCGT tips work a treat. You can get an almost Glass like finish with these if you take a fine finishing cut at high rpm. 👍

Thread: Searching for an Off-The-Shelf, Light-Duty, Rack & Pinion
02/08/2019 18:40:36

There's a few racks on ebay from old lathes about the size you are after. Might be worth a look. 👍

Thread: smooth cut in brass
01/08/2019 16:30:17

Slow spindle speed and high feed rate in combination with a cutter that has very small radius point can produce a poor finish like you describe.

Thread: What lathes have you had?
24/07/2019 10:13:26

I'm glad to see a lot of love for Raglan machines! I've always considered them to be very good indeed and hugely underrated.

Thread: ARC NCIH Part Off Blade

Thanks Ketan & Jason for your replies.

For the last 7 years I've been using Iscar GFN 3J IC354 inserts in an Iscar holder -

Iscar GFN 3J IC354

Everything is great about them, except for the price (even though they do last for a long time, to buy a whole pack of 10 is $$$). They are around $18+ an insert and I was wanting to move away to something cheaper like the NCIH Part Off Blade.

Many thanks again for the replies, I will do some searching for those MEM articles.

Kind regards,

Jim

Why not just swap the tips? The ones in the link look an awful lot like gtn3 tips. These are readily available and if you are prepared to wait they can be had for as little as 60p a tip from China.

Thread: What mills have you had
21/07/2019 12:57:12

My first and still the one I own today is my VMC knee mill, it was in a state when I bought it. It has no badges on it anywhere so I don't know if it's a Myford, warco or Chester varient but it has served me well.

I've since had several Dore Westbury machines which I restored before selling them on.

In the future I would like to replace the VMC with another but in better condition.

Thread: What lathes have you had?
21/07/2019 12:02:53

This kinda confirms what I suspected. It seems most people own several lathes before they settle on one.

21/07/2019 10:32:34

I was just wondering what lathes you guys have had. What did you start with? what do you have now? Any you regret selling?

Mine in order:

Raglan Loughborough (Excellent but basic)

Myford ML7 (Very good but limited through the headstock)

Boxford AUD (Excellent perfect for my needs my current lathe)

Unimat SL (Surprisingly capable little model makers lathe)

Sieg C1 (Never got on with this one)

Sieg C2/3 (Average in every way)

Thread: Rounded Torx Screw Removal

I had the same problem with a second hand tool. I just hit the carbide tip with a chisel to break it. The screw then just came out by hand.

Good idea! You win the cigar! laugh

I can't take credit for the idea I'm afraid. My Dad worked as a CNC machinist for a while and he told me this is how the workers dealt with carbide tips on damaged milling cutters.

Thread: Yet another "parting off grief" thread ;)
16/07/2019 19:05:38

Maybe there was some work hardening going on? Are you 100% sure it was mild steel?

I've noticed it, it's just one or two know-it-all types who like to dismiss anyone else's ideas and opinions.

I've had it and I've seen others have to put up with these negative people too.

Very good cutting tools, but IMO they never quite matched the quality of presto or dormer. They also made other item such as collet chucks which where up there with the best.

Thread: Milling a T slot - am I doing it right?
09/07/2019 16:39:01

I would cut each side of the slot separately. Using a smaller cutter first, that way you are more than halving the load on the cutter and allowing the chips to fall away.

Thread: A Chinese puzzle!
29/06/2019 17:56:29

Buying from a reputable dealer is no guarantee of quality I'm afraid. You should see the state of the quick change tool holder I bought recently from one of the very well known suppliers.

Thread: Do you use Chinese HSS?
29/06/2019 15:36:56

Cutting tools are the one thing I won't buy from China/India with the exception of Chinese carbide tips.
