Title: topslide setting
Post by: wheeltapper on September 28, 2016, 11:36:06 AM
Hi
Chester Comet lathe.
The numbers on my angle graduation strip wore away years ago and setting angles has been a pain.

I just started making some pullys to convert my minimill to belt drive ( dont ask :doh:.

I came up with this quick way of doing it.

this is the plate the topslide mounts on to,

I drilled two m4 holes on each side and at the front.

now I can quickly fix a steel strip on the side and use a perspex gauge to set the angle.

here's one for the pulley,

and one on the front for screwcutting.

I works a treat and it's quick.
the angles might not be accurate to 30 seconds but they are consistent.

hope this is of interest to someone.


Oh, in case you did ask, I trashed the low speed gear in the housing. :Doh: :Doh:

cheers Roy.

Hi Roy  :thumbup:


Thats a canny solution to the graduation problem , at times I am squinting to see if things are at the angle I require when setting the Myford compound over   :palm:

It seems that you were the only one who thought it was interesting, ho hum. :bang:

It's always interesting, we just don't always pipe up....   I know what you mean though, sometimes you wonder if people are interested.   Don't forget we get lots of lurker's.

As today is the 29th September, I don't think you have done too badly for interest.

Don't get disheartened if people are slow responding.

Wheeltapper (and all),

OK, this has been a pretty busy month for me with 4 "concurrent" design projects on the table.  This is the first that this thread garnered my attention.  [The Tralfalmagorians have been holding me captive.]

I often have to make cuts that are within .001 runout to a given angle.  The attached PDF shows the approach I came up with many years ago.  Hopefully, this will give you some ideas to improve your set-up.

Don't get me wrong, I'm not going to sit in a corner and sulk  :lol:
I just thought it had died.

I've only just seen it  :scratch: and I like it  :thumbup: removes any error  :thumbup: well as long as the angle plates are made correctly  :lol:

And that Roy, is precisely the reason I too changed to belt drive - and love it. In my case it was a quill drop whilst beginning to fly-cut. You aint alone my friend. Plastic confetti gears don't drive the quill at all well do they?

You're not wrong there  :bugeye:
It was flycutting that did mine as well, I was trying to clean up a chunk of angle iron that was apparently made from the core of a dwarf star.
Said chunk now resides at the bottom of the garden. :D

cheers

Hi Roy

I often feel like I am posting talking to myself   :lol:   

On the subject of angle things Arceuro  do a few sets of angle blocks that may be just the ticket for setups like yours .

I may have myself a set , a geeza can never have enough tools  :)

Well I document my rebuild projects so that I can refer back to them later on to confirm details - often years later. If others are joining me for the journey and enjoying it, then that's a bonus  :thumbup:

I think a lot of people read these threads but refrain from comment, but never the less benefit enormously in that they learn new 'tips and tricks', and the use of your angled pieces is a prime example of a good 'tip or trick'

Hi Rob
That's not a bad price for those angle blocks, if I ever have £30 lying around .

If I went that accurate I'd have to make sure the side of the plate was truly at a right angle to the bed of the lathe.

cheers
Roy.

ArcEuro ... Christmas is coming, the geese are getting fat... I think  :scratch: so maybe a subtle hint... or two  :headbang:
