AMERICAN NO 2 SELF-FEED CIRCULAR RIP SAW


This is an American No 2 Rip Saw. A recent arrival with the band saw behind.

One neat thing about getting this saw to the shop after being separated from its mates is that I have the parts taken off of it years ago that can now be added back. The flat belt drive parts and different feed rolls, the saws, etc. The sale inventory tag from 22 years ago is still on the guard. I don’t think this was ever put to use after 1988.

I will likely put it back by the molders where it was back at White-House Crawford for 90 years ripping blanks for the molders.

It’s not real pretty I know. But I am looking forward to using it.

Gang ripping capable. The arbor spindle is nearly five feet long. Three bearings.

Some of the feed works, outside end of the saw arbor shaft, two table lifting posts shining underneath. This will be an impressive relic to have running.

Three speed feed.

THE CLEAN UP

This thing is in pretty good shape. The guards did a good job keeping the works fairly clean. The top is cleaning up nicely. I will need to lift the top out to clean and adjust the arbor bearings.

The deck is now off. The stick is holding the feed belt idler out of the way. The idler looks like an add on. Seems like I read about it in an old article somewhere. It does give the tiny driver a lot more belt wrap. This central yoke looks like one of those leave it alone assemblies. Bolted and hot leaded. Certainly I don’t need to take it apart for what I’m doing.

The table rests on two pads like this one in the foreground. Part of tandem elevating columns. PS. Undo the counter weight before lifting the deck off.(!) This seems like a good oil arrangement. There is a small access screw in the table that is above the reservoir but this is easier.

Whoa. 58″ saw arbor. Three bearings. I am taking this out to put the line shaft drive pulley back in place of those v-belts. And to clean and tune up the bearings. The outside bearing is a lateral thrust bearing. The middle bearing was run hot. Bummer. The flange end bearing is great. I am kind thinking when they v-belted this thing they took the outside support away and didn’t get it back quite right. I’ll be playing with that some.

The saw arbor. Tiny feed works pulley. The large pulley will go where the v-belt sheave is now. I have had that pulley for 22 years before having the saw. So this is a reunion of parts. Retrograde. Or, un-retrofit. Or something like that.

No all I really wanted to do here was put the flat belt pulley on, shim the caps and be done. But it’s getting a little more involved. I am scraping the bearings. There are three points of bearing so I am doing the two main frame bearings first. The middle bearing wasn’t doing anything. It will now. I think being forklifted by the outside bracket may have altered things, or the v-belt conversion, or both. This is the time to try to get all three on the same page.

The outside bearing is a lateral thrust bearing. I had let this one down by loosening the bracket while I scraped in the other two, thinking I would shim in into position. But we’ll see. I may need to scrape this down too. The bracket was already bottomed. Just a little fussin’ is all. I was figuring I could tweak it around a hair like on my moulders, but no. Not here. Need to get about .004″.

Well I had to scrap this one after all. All done here but wanted to show the scraper for these kind of bearings.

I am so lucky to have this.

I show these views in case there’s a good blacksmith in the house.

Starting to go back together. The saw has two idlers. One on the drive from the saw arbor to an intermediate shaft, and another between a pair of step pulleys that speed the feed drive. These idlers have oil ports in them, but, they have been fitted with grease fittings. The grease fittings may have replaced original grease cups. I don’t know.

Here I am making sure the grease is free to travel though the shaft and into the pulley center. This idler can also be placed closer to the foreground on the idler legs.

This is the step pulley idler. You can see the grease escapes the center of the shaft through a small side hole. Now the idler pulley also has an oil port in it. I think that was the intended oil system because in this instance where the idler needs to follow the belt over the three steps, that would be the only way it would remain oiled. The grease fitting is fine so long as the speed is always in the first position.

The big step pulley also carries oil. It free wheels until the feed is engaged.

Here’s a close up of the manufacturer’s info. The brass tag and Shop No. tag have been removed.

The bearings are scraped. Shimmed. Wicks returned. Reservoirs packed with waste, new to me but that’s how they were. Belts shortened.

The beauty of babbitt bearings. Decades of service and we lose one .012″ shim each side. A ball bearing machine would have cost me hundreds of dollars in bearings. These will cost my time and two small pieces of paper.

Panda? You know what this means. Wanna race?

UP AND RUNNING

The saw is now running off the line shaft next to the molders. Closer to the molders and oriented in the opposite direction as it was at Whitehouse-Crawford Co..

The spur feed roll grabs with certainty. It works rather nicely. It will take some time for me to learn to use it. Not real sure how close to set the feed, how much it should rise, etc..

have yet to make a shipper for the tight loose pulleys on the countershaft.

Here is the belt arrangement. I had considered hanging the counter above but this was easier and will be easier to take care of. There will need to be some guards made in conjunction with an out feed table. This will place the rippings right at hand for feeding through the 8″ molder.
