He needs to be broken down and scrubbed good. Pic #4 is where all the action is. Carter used to make some parts to refit older saws ... might get some ideas there (ball bearings are the way to go). How are the tires? .... look kind of rough in the pic's.

Tires are shot. But they may still keep the belt on. I will replace them with the new urethane tires. I put them on my little Craftsman and it was a lot quieter and seem to run smoother.

That guide system is antiquated compared to the new style but it worked for 90 years.

Isn't so bad if you use cloth or strips. Draw the shape of the "petals' on some cloth, cut out and laminate! Too lazy to wait for conventional resin to dry? Use the UV cure epoxy and a 4ft black light tube. Sets in 5-10 mins.

I've built entire planes out of fiberglass. If I never see it again, it will be too soon. I think I developed a slight reaction to it which is not unusual.

I desided to turn my first horns as 1200hz tractrix out of ash logs. They will crack in time but that can look cool too.

CorrosionX really will clean up rust, and will last far longer than kerosene based lubes. More expensive, but a better value.

It lasts for a long time even in salt air, and is safe on electronics- they used to demonstrate a TV working completely immersed in the stuff.
Really good for eliminating bi-mettallic corrosion.

I need to order more, but have three or four cans of other stuff to use up before I do.

With the tons of pretty iron you have, some CorrosionX would be a good investment.

PEG-1000 soak after turning?

There is an outfit called "Strong Arm Sprays" very very good for metal restoration - on the web.

As far as Ash, not so great for turning, imo. Consider some maple?
Get ur feet wet on simple pine... just to see how stuff works...

You can make up blocks to have the heatstock and tail stock lifted up machined for you (or you can make) and get more swing...

If you want to consider laying up a horn, fiberglass is not the only choice, Martin Seddon reveals all of his methods on his site. FYI...

I'd never use pine. I did that years ago and the tear out drove me nuts. I happen to have Ash logs on hand. My inboard swing is 30" and my outboard swing is 84" so I don't need to change the configurations.

I'll check out the Strong Arm Sprays.....thanks.
