Sorry its in the wrong thread

 

I would like to congratulate Stephen Wessel on his Modern flute making articles. It is most informative and Stephen details many clever techniques.

Thread: Computer very slow?

I have an older xp computer and have found that Auslogics disk defrag is super for it . Free download and run the optimise program , it speeds it up nicely.

Thread: Lathe Chuck Attachment Methods.

I made my own smaller version of a camlock fitting on the stepperhead lathe, which as stated in previous posts is accurate and quick to remove/replace. Plus the benifit of being able to run in reverse safely releases opportunities in machining operations not available with screwed chucks.

Hi Hopper,

Yes I know it was provocative to even mention it and I thought I had got away with it, sort of scraped through so to speak. but anyway it worked for me.

Hi Hopper & Roger,

I have described a Lever Locking topslide in detail in previous MEW magazines numbers 119, 120 & 121 as well as describing the construction & drawings on the Stepperhead lathe, which used a toothed belt drive, in the MEW magazine. The Milling drilling attachment is also somewhat similar to the one I detailed in MEW 223 for the Stepperhead lathe. There are some differences in the Chipmaster lathe photos but in essence they are very similar. I machined the nut from acetal because I tried moulding the threads, but because the fit was so close the friction was too much and it seemed that it was going to take forever to get a nice feel to the operation. Acetal is cheap and very easy to screw thread and slits in the nut can be compressed with the fixing screws for very little backlash. This has been detailed in the mag.

I made a similar vertical parting tool and it worked very well. It was described in Thread: Parting Off MEW225.

I have had some problems with my computer which are now fixed and I have chosen Kaspersky as my virus scanner. However it seems to be very diligent and will not allow me to access www.homeworkshop.org.uk it tells me it is a phishing site. Does anyone else have this problem and how can I get round it?

Well done Michael

[this was probably easier than doing the paperwork for the alternative outcome] If you can laugh like this on 33 rpms what can you possibly do on 78 rpms?

Very Best Regards

How about, I would love to give you a % but I could also say that I thought of it before you did.

Hi Mark

"Alan, very nice and simple ,is the spindle just floating in the steel body ?"

It is not floating the spindle runs on a 10 degree tapered bronze bush at the front and a plain parallel one at the back with adjustment to eliminate end float. As to the mesh with the spur gear, it seems quite good enough and has seen plenty of use but shows little wear.

Hi Mark

Here is my version. made from mild steel and uses a 40 tooth spur gear ( an old lathe change wheel) Has had much use and works well. Centre height is set to suit my lathe centreline when it is mounted on the cross slide. More photos in my album.

Thread: Tool and Cutter Grinders.
27/10/2016 18:26:41

I had a go at this with my Stepperhead lathe, the biggest problem was working out the helix. I guessed the cutting angle by setting the diamond grinding wheel height. It worked but it was a lot of setting up. How would you sharpen say a 2mm end mill flutes, just buy a new one? https://www.youtube.com/watch?v=yMxv1jU-R_A

Hi Blake,

I hope this is not classed as an interference on this thread, but since you ask. I put the original motor inside the column. I cut an oval hole in the back of the column for the motor spindle and brought a new shorter vee belt. It works great, I have run it for long periods and it only gets slightly warm. This then frees up the top surface for the Dore Westbury head You can see more photos in my photos.

Thread: Weird lathe bed
14/09/2016 10:12:16

On my Stepperhead lathe I used the front bed guide as a narrow guide with the gib strip on the outside dovetail and used the inside vertical face of the saddle as the guide face for the full width of the saddle. The rear be dovetail has a dovetail gib strip adjusted to prevent any lift of the saddle. The leadscrew is positioned centrally and as high as possible between the bed guides to minimise the twisting moment from the leadscrew pushing or pulling the saddle. both gib strips are dowelled in position.

What is so wrong with using TurboCNC in a DOS computer even an old laptop with a printer port. It works good enough for me in my Stepperhead lathe? Is it too retro?
