New Old Shaper - Atlas 7b

<< < (3/9) > >>

rockknocker:
Vtsteam, I looked at a couple of the local hardware stores here, but all the wire they carried appeared to be galvanized steel wire. Silly me, I didn't think to look at a music store...

Here's a video showing the play in the ram. Should I be worried about this?

My next step will be to remove the ram and ram lever to get access to the bushing and assess the condition.

Its a loooong time since I used a shaper!

1. Wear in the bearings/ram mechanism is unlikely to make that "clacking" noise

2. Shapers have various bits of linkage to provide auto feed to the various movements of the work table. The noise sounds like it maybe comming from the right hand side of the machine (as seen from the front and in the start of the video) That side seems to have the auto feed bits and pieces!

HTH: Will

Recall that old car mechanics would use a stethascope (i.e. Big screwdriver: Handle in ear, blade on engine to diagnose were the noise was actually comming from.

Still used today by modern diesel engine makers who provide a digital audio signature of big ( like ship's or earth mover diesels ) from new so that diagnostics could be performed to predict wear.

At this size of engine there's no such thing as routine maintenance! You listen, and if you detect a bearing or whatever wearing out then that is replaced, only.

Funny thing, I'm not actually sure if you can get music wire at a music store!     Hobby shops, for sure.

Rocknocker, the back and forth play in the ram is very likely to be wear of the sliding trunnion which runs in the slot in the yoke linkage. There shouldn't be anywhere near the slop that you are demonstrating in the vid.

Play in that area may be as a result of failure by the past owner to adequately lubricate the trunnion and yoke slides.

I had exactly the same problem with my Alba 1A shaper,and also the bushes and shaft which the bull gear runs on were badly worn on mine causing the gear to wiggle about.

My solution was to make a new larger dia housing for the bull gear bearings and upgrade to sealed ball race bearings(fit and forget).

An oversize trunnion block was made from bronze and the yoke sliding faces were remachined on the milling machine to remove all score marks and the new trunnion finished to give 5 thou clearance.....OZ.

Will,
That's interesting, another thing learned, this time about ship's diesel engines!
The feed mechanism does make some noise, but I had it in neutral for the video. I haven't gone through that part of the shaper yet, so it may have issues that could be causing this.
