Hello Lee, good afternoon.
Lee: – Has anyone Built one of Dave's Gingerly shaping machines without having to any of the casting, by building up the frame from steel plate and nuts n bolts instead?
DC: I started building a Dave Gingery's shaping machine and just missing me build a base and apply an engine. In the construction of the shaping machine I did not use any cast element. Basically I used aluminium plate from where I carved and cold rolled steel. And, yes, many nuts and bolts as you can see in my album…
Lee: – I have been thinking of buying the book dave gingery shaper for the plans / dimensions
DC: – Dave Gingery's book was my starting point and my guide. However I made some modifications.
Following is the list of the most important:
1 – I did not use bicycle chain and sprocket-wheel for movement and instead use synchronized wheel and belt in mechanical conversion of rotary motion to reciprocating motion.
2 – I did not used bronze bearings on the main shaft. Instead used a double needle bearing.
3 – In each of the remaining bearings, for lubrication, I built a hole and a small cavity where a piece of felt fits dipped in oil.
4 – The ram does not move on aluminium tabs. They move on a bar cold rolled steel (in each side) and I intend to use UHMWPE tape (see, please, http://www.theptfeshop.com/product.php/28/uhmw-tape—0-25mm-thick/8b342268fcfea1fbcf234c54629ebc51. This alternative was recommended to me by Mr. Rick Sparber, who used it in its shaper and also helped me with valuable opinions in building the shaping machine.
5 – Also the automatic horizontal advance, at least temporarily, will be automatic in one direction only. I only need to build a new "ratchet pawl".
6 – Instead of building an aluminium work table, I will apply an angle plate bought from Chronos (see, please, http://www.chronos.ltd.uk/acatalog/info%5f110710%2ehtml).
If I can help you with any thoughts or information, I will do it with pleasure.
P.S.: I'm sorry I couldn't get rid of the white background. Don't know how it appeared in the post…
Best regards
Dias Costa
