Had a quick attack on a lump of CRS and I still need to get a handle on adjusting the position and length of the stroke to get it where it needs to be.
I also have to do some beating on the belt guard, as I think the PO made it and the feed mechanism catches on it. Also it is a little cumbersome in how it fits and no matter how tight I do up the mounting bolts it is quite loose.
I'm hoping to borrow a friends pressure washer to give it a clean on the weekend.
Thanks Dave - it was the electric motor I was interested in and I think I can see the problem with mine. The junction box hits the back of the column, preventing full tension being applied to the drive belts. I'll have to move the motor back a little.
Today I stripped it down and hit it with the pressure washer. As is often the case with old machinery, someone has repainted it at some point and not done a good job in their preparation. As a result, the degreaser caused some areas to crinkle and the pressure lifted paint in others. There are still some areas than need a second go but there is a big difference already.
I took off the clapper head and box and put them in the electrolysis bath for 15 minutes and the results speak for themselves. I need to do the actual head assembly but couldn't see how it comes off the ram. I ran out of time today, as I had to be home early, so this will have to wait for another day.
After its bath:
The ram, box, table, gibbs, leadscrew etc in the parts cleaner ready for a good clean:
back out the bolt that you tighten up to hold the head in position you will have to back it out probably all the way, there should be a wedge pin under it.

I did try that but it seems to be a cam as it is loose in the centre and tightens up when turned either CW or CCW. Now that I think about it, I should have a look under the ram now that I have it off the shaper. Didn't think of it at the time!
Turn the square head cam bolt until it loose, then pull it out. You can then pull the head off and if it needs adjusting when you put it back together it has a fine thread to adjust it so the cam works just right.

I continued with some cleaning over the weekend. I placed the head into my electrolysis bucket and flicked the switch and then went back to scrubbing bits in the parts washer.
The head came out nicely and the pictures don't really do it justice. The metal is certainly not shiny and bright, but not a dark as some of the pics show. Essentially all the rust has gone and I can now see the divisions on the protractor.

Straight out of the bucket:
Back on the shaper:
I did give the handle a quick brighten on the wire wheel but I think I'll leave the head as is (with a coat of light machine oil).
Whilst putting the shaper back together, I decided to make up a hand crank, as to set the stroke you have to mess about with the hand wheel on the opposite side. Nothing too exciting - an old crank handle I had found, a chunk of 1018 and part of a broken punch. Some turning, drilling, welding and grinding!
Darren, that first photo looks amazingly like the crankshaft pulley from an old Allis-Chalmers Model B tractor, many were crank start and magneto magneto equipped.

Hi Dave,
I've got a PK Douglas Shaper which may have been manufactured before the conical arrangement became an option or perhaps the option was declined. It's my intention add a clutch to the Douglas for the convenience it will provide.
May i ask, do you currently have a Douglas with clutch and are you able to share any additional photos and possibly measurements of the clutch components and linkages to assist a replication of the clutch for my machine?
with thanks for your consideration of this request, John aka castellated nut
