Thread: Could I try an IC engine?
11/02/2021 16:51:05

Hi Paul,

Have a look at Andrew Whale's "hit & miss" engine. It might not be exactly what you're looking for, but an interesting IC project non the less.

I think Jason's right. Shop around or be patient seems to be the name of the game.

As Ramon says. If using Super Glue, use a "non-fogging" one. To be honest, I didn't know such a variant existed. Just goes to show.

Thread: Cutting on return traverse?
07/02/2021 16:42:19

Thanks everyone for the comments and suggestions. I had no idea the issue was so common. Yes, the WM250 lathe may not be as robust as some, but it did take me a bit by surprise. I can see a few trials coming up to see which method works best.

Good afternoon,

I've searched the forum and the internet, but to no avail. Maybe I'm not using the right search words.

Irrespective of the material, when cylindrical turning, the tool cuts slightly when returning the carriage for the next cut. Power feed or manual. Even with a relatively small 0.12mm depth of cut. 30mm stock protrusion, 12mm dia. Tried various spindle speeds and feed rates without success.

Cross slide and compound gibs are adjusted and headstock bearings feel OK. Lathe is a Warco WM250.

Envious? Just a bit!

Thread: How to align a fixed steady?

DC31k mentions the use of small rollers instead of fingers. While this sounds like a good idea, I'd be concerned about small shavings being crushed into the workpiece. Fingers will simply brush the shavings aside. I have the same concern with roller blade guides on a wood bandsaw squashing resin onto the blade.

Novel idea, and clearly only suited for light cuts. Not sure why it needs such a large overhang though? A smaller overhang would increase rigidity.

Thread: Dasqua DTI.

Decided eventually, well in for a penny. The initial breakaway torque was very high, but once on the move it feels about as I'd expect.

Thanks for your comments.

Thanks old mart, I'd love to provide a close up, but my phone still has buttons and I love my 35mm OM4Ti. Seems a simple question for Chronos to ask their supplier, but so far, to no avail.

Thanks Derek, I'd be surprised if it didn't move, if only to protect the movement, after all, 0.8mm of working travel isn't very much.

02/02/2021 11:44:45

Yes John, that looks like the same one, except mine has a plain white face.

Good morning,

I have a Dasqua DTI which I assume would have a friction pivot/clutch. However, the lever stylus does not want to move (other than operational travel) and I don't want to force it. I've asked Chronos, but they don't know and can't get an answer from their supplier.

Can any of you knowledgeable folk help please? It carries the number 5221-1001 if that helps.

Thread: Machine corrosion protection
31/01/2021 15:58:07

Three suggestions:

Proprietary rust preventative fluid. Solent and Ambersil products work well.

Dehumidifier. "Desiccant" type rather than "refrigerant" as they perform better at lower ambient temperatures.

Machine cover to reduce the amount of airborne moisture falling on the machine.

Thread: Die query?

Thank you Howard.

Another vote for these guys.

Thread: Die query?
29/01/2021 10:38:36

Thank you,

Any idea what sort of things would they have been used for?

29/01/2021 09:46:06

Good morning,

I've been sorting through some acquired taps and dies and came across a die with the engraving "3/8 x 26 BRASS", made by LAL ltd England. It's a conventional round split steel die.

Too fine for BSF or UNF. Any suggestions what it's for?

The REAL moan is how they make it so hard to contact them when things go wrong.

Why does that not surprise me. Just like our local authority, the reporting process is so contrived and non-intuitive that you just give up and don't bother. Job done, no cost to put things right!

My WM250's motor is brushless and has a mag pick-up on the lathe spindle.
