Shaft Treatment

Throw Off Linkage Shafts

Throw Off Linkage Shafts

Yes it has been unbearably cold! So I got done little with working on the cold cast iron. But there are some new pictures of what I have been concentrating on lately: Polishing shafts. Here are the throw off linkage shafts.

And the back shaft with the side arm still to be done.

And this is what the rear of the press looks like right now. On some of the parts I noticed the old ink remaining here and there seeping through the paint. So I will have to go for another coat.

Oh and I was able to pull out the key holding in the pinion for the main gear that I talked about in the last posting. Seems every time I even think about leaving something and then get at it I discover more. This time it was that the key was not the right width, but was too high and had been filed to a taper – and then was driven in only one third of the way! Good thing I got it out, now I have a new proper size gib key on order.

Some Days are Easier than Others

Friend Tom with Press at Rogers Pass

Today was another day of rust removal. Now my order at Acklands came in and I have better emery-cloth and some rust remover to try out. Had bought a new set of wrenches at Home Depot, an open end – close end ratchet combination set in the typical heavy plastic packaging that you need a set of shears to open. When I came to use the 9/16″ wrench I find the ratchet did not work, and looking at it closer it was a used wrench of a sightly different style (still a Husky though). Back to Home Depot for a refund, but that was not so easy. Even though the packaging claims lifetime warranty there was a lot of waffling going on, I felt they were of the opinion that they were letting me get away with something. Frustrating.

Then a slight, could have been bad mishap. I had attached the throw-off lever linkage and left the lever pushed forward. Then I worked on cleaning rust off the platen and the tympan bale areas. I left the top bale folded down while I got busy with something else. As I turned the flywheel cleaning the main rocker shaft I felt a bit of resistance on the flywheel. Hm that’s not right. As it turns out there is just the right amount of extra space left in the throw-off position so that the bale just gets squeezed a bit – without damage.

Note to self:
1. Never leave anything on the platen that could cause damage.
2. Always turn over the press for a full cycle by hand, and check if anything seems to take too much force!
3. Never leave the platen bales open!
