i have a 15"Hendy shaper that i am having problems with. It was origanly made for a line shaft so it has a brake in between two pullys http://i15.photobucket.com/albums/a371/jasonjoiner/shaper/100_0153.jpg well it will not fully engage the brake when it gets to the end of the stroke http://i15.photobucket.com/albums/a371/jasonjoiner/shaper/012.jpg

I think it has something to do with this piece but im not sure how it works i have adjusted it in both directions http://i15.photobucket.com/albums/a371/jasonjoiner/shaper/011.jpg

then it could be this but i dont know how the piece work as it does not even touch the stops http://i15.photobucket.com/albums/a371/jasonjoiner/shaper/014.jpg

does anyone have any ideas?

Dilligaf, Is it not concievable, your "brake is a clutch for forward & back motion to ram, Maybe your shaper should have one open belt & one crossed belt from line shaft pulley, Some of the guys on Practical machinist.com know old Hendeys inside out.

I think oil mac is on th right track. No experence with your shaper but the one line shaft I saw needed a lot of oil to free up the clutch and get it working right again. Gary P. Hansen

i think oil_mac may be on to the problem. have you ever had this machine running, or did you just get it? the shift mechanism shown in the second and third photos should switch between drive pulleys, and one of the pulleys should run in the opposite direction from the other. this is usually accomplished with a twisted belt. how are you driving the belts?

i know about the belts the problme is it does not fully engage the clutch in the pullys when it hits the stop on the top of the shaper and i can not figure out why. http://i15.photobucket.com/albums/a371/jasonjoiner/shaper/015.jpg

You need to take the belts off to keep from getting oil on them. Then really soak it with WD40 or better and then work it back and forth until it completely frees up. Gary P. Hansen

Take it all apart and clean it up and inspect the workings . That will fix it or you will.

I think everyone is misunderstanding my question it all works great if i manualy move to lever to change directions. If i let the shaper do it it will not fully engage the brake. I need to know how to adjust something so the shaper will engage the brake fully.

Not trying to be a smart a-- .but think something is worn or wore out in the linkage. With out being dissembled adjustment I don`t think will fix it . You need to take apart the mechanism and figure out what is worn to the extent that it will not trip are move far enough. Old machinery like that wears over time probably why some one got rid of it.Not enough since to fix are repair it.

i get ya now. i would operate the lever manually, and make note of just how far you must move it in each direction for the pulleys to work correctly, then run the machine to watch how far the lever moves when the ram moves it. this should show you where you are not getting the proper movement. then you'll need to figure out what to do to get the lever to move correctly on its own.

i apologize if you have already tried this.

Try on the practical machinist forum under the antique/old machinery section.
Some of the guy there have Hendey shapers and might have a parts book. There are also some parts books at the very bottom of the listing.
They probably have had the same problem.

It appears that your drive pulleys are to far apart. My 15" Hende has only approx 1/8 inch clearance between the 2 outer pulleys. The central (of the 3) pulleys needs to engage the outer 2 pulleys equally.

Also, all of the spacer washers are on one side of the shaft attachment (3rd photo). Try centering the attachment point with the washers. On my machine, the total movement of the shaft (in and out) is 3/4" to 1 1/4".

I have not had to disassemble my drive system, judgeing from your photos the above may be part of the problem

Hope this helps
