Shaper saw

<< < (2/4) > >>

John Hill:
Not all shapers have powered down feed but I guess it would be practical to mount the saw on the clapper box and allow it to pivot up and down with a weight on it to keep it cutting then it would be a mild talk to occasionally advance the down feed manually to keep the saw more-or-less horizontal. :coffee:

There was a little tiny one came with my shaper that I have never set up, it has a spring to encourage the cut instead of weights. :scratch:

First I would like to introduce myself to the forum members.  I just am newly acquainted to MadModder thanks to the link that Darren made to the Practical Machinist.  Photobucket sent me a traffic report which showed that the traffic generated by ModModder viewers was far supperior to the views originating from the PM site. 

First of all  "Thank you Darren".  Perhaps it is serendipity but I think you should have included a post in that thread that would have alerted other Shaper owners that there is a forum here that will be of interest to shaper owners.  I have tried, unsuccessfully, to get the PM site to open a Shaper Forum but the PM owner has preferred to have forums that reflect his personal tastes.

It would really be something if the MadModder would favour us with a Shaper site where we could post tool profiles and modifications that would benefit all owners.

The Power Hacksaw pictured above was made last week.  The downfeed is via the automatic downfeed.  A new post was made to fit snuggly inside the saw's vertical member.   

I do not believe you can rely on the Clapper to act as the downfeed because at the end of the stroke the angle would be very acute forcing the blade up suddenly and most likely breaking something.

The following is the text that was included in the PM site:
Mr. Admin, the Elliott 24" is not an Antique. Please feel free to move the thread to the Shaper Forum.

This is not a new concept but it solved the problem of cutting material that my other saws could not (not the piece shown). It is a compound mitre saw.

In this case there is a 24" band saw blade. The holes in the horizontal bar are for an adapter that holds 15" Hacksaw blades if required. The holes in the end piece should hold a boxing glove.

A return stroke lifter has not been incorporated yet. The saw has to be watched if the feed is aggressive because the blade will not be able to keep up.

Lubricant was sprayed on for demonstration purposes but a dedicated coolant nozzle and coolant tray should be used at faster speeds.

The one that Nevil Shute made is shown here http://www.nevilshute.org/Engineering/ModelEngineer/convertingshaper1.php  I rather like that story as he had a petite little machine like my "Sally Shaper".

Thank you for that link.  Though I have read 1/2 of the books he wrote I was not aware of his shaper interest.  It certainly has not escaped me that he was technically very capable and accomplished. 

Like I said it was not an original idea.  It was meant to encourage others who may not have seen this Shaper adaptation or extension, so to say.  The saw allows me to make use of bigger pieces than I could before.  It is always possible to make a bigger one if need be but I suspect that I would require at least 2" blades to have sufficient stiffness.

John Hill:
Welcome RDL, or as we would say in this part of the world "Yea wull g'day".  I have a small Adept 2 powered shaper, I suppose some shapers are classified as 'bench top', the Adept is more you coffee table size but she (it is only right and proper that such a petite machine should be given a female personality) can get through a useful sized job in quite short order.

Regarding saw attachments you may notice in the Nevil Shute example he got over the acute angle problem by mounting his saw frame on a long arm.

Bernd:
Hi Raymond,

I don't think Eric would open a section just for shapers, we need to let him decide on that.

If you have any shaper related subjects I would post them in the Shop section of Madmodder. I can't see any reason for not putting the related items there. The machine itself can be disscussed, the tooling and so forth. We try not to make any section to specific to subject since we are trying to imcompass all things that can be "modded".

Regards,
Bernd
