My first ever lathe is a Myford

[gerritv]

I copied @McGiver on my note because he is the author of the article you referred to. I copied @gerritv because he has made a simpler knurler. I'm interested in their opinion of how easy it would be for a beginner to make one. I don't think it's a, slam dunk at all but those two guys are infinitely better qualified to assess that than I am.

McGyver's is not a beginner one, have to make or source gears for his Plan B style. The Plan A style in his article is quite attainable with a milling machine, a lathe and some care. And sharp edged wheels, best to get ones specifically for cut knurling.

My design is simpler, requires a real cut knurling wheel, but is really only suited to coining/straight knurls. I also chose to buy the bushing etc, which added to the cost ($98 total I think).

Arbutus also made one afaik, his could do coining as well as 60degree knurls.

All of the above need at minimum air blast, preferably with some liquid spitting, to clear chips. You should be doing this with pressure knurling as well of course.

Using mine on a Sherline wasn't a great experience, but works great on the King KC1022.

Well I finished my first project for the Myf. A tool height gage (for the lathe but done on the mill).
This is a modified Joe Pie method.
I used an old (but good condition) bushing in the 4 jaw, measured the diameter and then selected the approximate gage blocks to = half the bushing diameter. The set-up looked like this:

The horizontal parallel placed on both the top of the blocks and bushing shows that the height gage is still too tall. Nice thing here is that by using a feeler gage you can tell how much more to shorten the height gage.

You can also see the gap (between arrows in next picture) to help zero in on the right gage height.

Here’s Joe Pie’s method - using a DTI to check that top of stacked gage blocks = top of the bushing. (I did both, but prefer the parallel across the top).
Here’s the finished height gage, checked from both sides with a parallel

Nice job Craig glad to see as these guys try and decide what you should do you are happily doing what you want

Fyf’s FIRST CHIPS!
I used the new height gage to set the cutter. I’d previously set this cutter on the center of a 1/16” drill bit (pics were posted above somewhere) but height gage showed that it was off! Off by quite a bit.
First cut was facing a rusty and uneven piece of 1” dia rod of mystery steel (just hot rolled i guess).

Next cut was to clean up the face This was a pretty big cut. Loved it - so very smooth, quiet and finished dead center. Thanks to the height gage.

Here’s using the QCGB to control lateral feed


Final results


BIG HAPPY FACE HERE

Please excuse - but i should have included this pic first.

Congrats on your first cut!

@CWret really nice work on your standard!

We have an Edit deadline now?

Sorry I offended... OK, maybe not all that much... I don't speak in code. Spent almost thirty years working in an environment that sold toad-code as THE answer, when the Franco guys, in reality, were looking at the English side of the Tech Manuals, to figure out what they meant! (which is to say, the translations were a day-glo abortion, and Like the guy said, most of the money spent translating the Tech Manuals to being supposedly Bilingual, was wasted! Mostly because they invented a lot of new words for stuff that even the Franco's did not understand.
True story, they were some pretty decent folks to know. Despite the politics (and their complete ignorance, intended I am sure, of the actual history of this Country!). Most had no idea where the Canadians got their ambition to follow the Commonwealth!

Anyways.

But I note that there is no longer an option to edit any of my prior posts.

Glad your lathe is working well, and equally glad that the height gage you made works! For now! LOL!

Try not to spit when it doesn't, if that time comes!

I believe your premium membership has probably expired. Regular members can only edit posts for a few moments. Premium members can delete and edit their own posts indefinitely.

Regular members can only edit posts for a few moments. Premium members can delete and edit their own posts indefinitely.

I upgrade to Premium shortly after joining - so I never realized that editing privileges came with the upgrade. Similarly the upgrade allows me to add pictures to a PM. Again - I just thought that was available to everyone.
Point being - I suggest that administration should point these advantages out on the ‘membership upgrade page’.

Same, on all counts!

 

[Susquatch]

I will endeavour to put something on the upgrade page.

The premium membership features pre-date me. But it's my understanding that the features were more of a way to say "thank you" than bait to donate.

There are not many.
1. Unlimited ability to edit and delete posts.
2. Ability to attach photos to PMs.
3. Access to a Premium Members Lounge - which isn't used much. (added by edit per CWret comment below)

All levels of upgrades get the same features.

Plus-

3. A very under utilized ‘Premium Members Lounge’

(Thanks! See edit above Susq)
