I'm not complaining. The beer and popcorn were free. I never get tired of watching Sally Shaper do her thing. :D :D
Cheers :beer:

It is a pretty machine John... Should we really be saying that? :borg:
Was that on your phone? Pity we couldn't see it doing it's thing a little better :(
I'm sure at some point you'll get a better vid of it making something special :thumbup:

Video was way too short John :poke: :lol: :lol: :)
Did you make the tool holder ? i must get round to making one :dremel:
Do you generally have the tool holder mounted in reverse or just for cutting a slot ,, meaning less dig in / better finish :med:

Didn't see this until now. Busy weekend and not much time on. That's a nice looking machine.
I really want a shaper now!

Yea, my little camera is really unsuitable for this job and Flickr seems to have cut the video down to about half its length..
Maybe I can paint a piece of scrap as it is impossible to get any image of that shiny stuff!
The tool holder came with Sally and I usually use it that way around, I think the previous owner made it, it is a neat job.
To be frank, this little shaper has so little capacity that I found it impossible to cut a slot using the manual down feed, just a tiny bit of extra bite and it was all over. The ratchet and flexible cable is a quite simple modification and I cannot understand why all shapers do not have them.

Nope. It didn't show aluminium chewing bit showed me all the cable driven down feed. Briliant. I was drolling over one shaper a year ago and then I was thinkking a stepper motor, cables, drivers and works. I know - I have degree in ee. There was easier way!

Might I respectfully suggest that you access the Ian Bradley book as I suggested elsewhere?
There is not a lot of difference between his Atlas mechanical downfeed which should be applicable to other small shapers.
What you have to know is Bradley wrote vast and authoritive articles both as himself and as Duplex in collaboration with Dr Norman F Hallows.
With very little up dating, the information in all their articles is just as valid today as it was then.

For those who don't want to Google it, here's a link. http://www.neme-s.org/Shaper%20Books/The%20Shaping%20Machine/ (http://www.neme-s.org/Shaper%20Books/The%20Shaping%20Machine/)
Thanks for the suggestion.

Ian Bradley made a really nice job of that downfeed and so much more of a 'project' than what I did, but I think I will stick with the simple system I fitted to my little shaper.

John,
I really like that cable driven down feed! Have you ever done a posting with some more details as to design and construction? I know Fergus likes the Bradley solution but I think your design lends itself to easier tilting of the downfeed. I'm thinking about adding something similar to my 7" Aamco. I have some car manual transmission shifter cables laying around....
:dremel:
I did a search but was unable to track down any detailed posts.
Thanks,
Chrispy

Hi Crispy, no I never did any drawings and the way it worked out is not very elegant, it would not be very difficult to figure out. The idea is pretty simple really, a ratchet wheel is mounted under the downfeed handle and a cable operated pawl can be engaged with the ratchet or swung out of the way when manual feeding is required.
The cable is attatched to a convenient reciprocating part of the mechanism, I found a place of the drive to the cross feed to attach mine. The cable is arranged so that the cable outer is moving and the inner passes through a fixed, adjustable anchor. Adjusting this anchor allows more or less cable movement which in turn adjusts the number of ratchet teeth to advance each return stroke of the ram.
