Bushing for 5913 Apron

[ltlvt]

Does anyone else make their own decorations for the Christmas tree? Just kidding I am making the bushing for the hand wheel on the 5913 Apron. Why Clausing did not bush the hand wheel from the factory is nuts. All the rest of the shafts for the apron gears have replaceable bushings. Even though there is a ball oiler on the hand wheel shaft it seems that nobody too the time to oil it. The shaft itself has already been built up with weld and turned down but it is below the normal .750 diameter and the hole in the casting is above the o/d of a 3/4 " bronze bushing. so here I am making a custom bushing for it. The material I am using is some kind of bronze shaft material that I picked up at a salvage yard 40 years ago. I love re-using things for my projects. I just a little on the Red-neckish side when it comes to throwing things away. Coming from the poor side of life it just comes natural to me to look at junk as inventory. Takes time and creativity to use some of it but I consider it money n the bank when I don't spend money on inflated material prices and then pay inflated shipping cost on top of that. Sometimes I think there should be a thread for "What did you salvage today" ?

Nice job on the bushing and saving the turnings too! Being frugal is something that can
pay off in a big way at times.

I save all my brass turnings and small bits. I do have a Johnson furnace that I can melt
brass or bronze in but havn't fired it for a while. Also I save cartridges discarded at the local
gravel pit. I have two of the five gallon pails almost full now. Most of it seems to be 223 and
look to be fired just once. Also I will casually part an old transformer or electric motor for
copper and pack rat it in a shed for later use. Your salvage idea is a good one and would
likely generate a lot of activity on HM.

A bronze that makes continuous chips would not be considered a bearing bronze. A tin bronze is hard to cast without lots of porosity.

if you look closely at the picture, you can see a lubrication groove in the original surface. I wonder what it was originally. I have 2 pieces of it same length and they both have the lube groove in it. Identification is always an issue when using unknown materials.

I don't know what a Johnson furnace is. I've been wanting to make my own from an old propane hot water heater. I have lots of cast aluminum I could repurpose if I had a way of re-casting it. I've been watching some lost foam casting videos lately. they seem to use charcoal as the fuel. I would prefer propane if it will get hot enough. How hot does it need to be to melt bronze?

It's a crucible furnace that uses propane or natural gas. It has a blower that makes a roaring fire in the chamber.
It's big enough to hold a crucible that would accept at least 20 pounds of brass. Most brasses and bronzes melt
somewhere around 1700-1800 degrees Farenheit.

I had to do the same thing on my MK1.

They went by the "Wears like IRON" slogan and in reality it was a good decision.

I agree it was a good decision the bad decision was when the owner did not oil it regularly. My model 100 is not worn but it has a flip top Gitz oiler. Ball oilers are the most likely to not get the attention they deserve. Many of them get covered with paint.
