Simple reducer

[Braeden P]

Hello would any one be able to make me a simple reducer
2.5 inches across can be 5 thouthands under size but only a few over preferably under size.
0.125 inches thick can be from 1/8 inch thick to 3/16 inch thick.
1/2 inch hole in the center can be drilled or reamed if you like to over do
I can supply 3/16 of an inch thick aluminum plate that I can supply but I would have to use a hacksaw to cut it or you could cut it if you have a band saw. This is to reduce the size of bore In a gear so that I can use it on my power hacksaw build.
It is for the big aluminum gear that I will use in thes project.

Homemade power hacksaw

I want a bandsaw but no space want a power hacksaw but no money but with metal I was given along with some gears I’m starting to build a power hack saw . I have no u channel but some 2.5in by 3in angle that I will use. I have some more metal but it is 3in by 3in by 72in by 1/4in hot rolled each...

Draw a picture on a piece of paper, photograph the hand drawn diagram. From your description, I am confused.

Are you talking about sleeving a bore?

I drew it up but now I can’t find it I will keep searching for it

It is just like a huge washer to go in the counter bore of the gear so I can put it on a 1/2 inch shaft.

I'd suggest making it stepped so that the finished reducer is the full width of the gear. That's a big gear to be sitting on a 1/2" shaft with 3/16" support. How's the insert going to be attached to the gear and the shaft?

The gear is 1/4 inch thick alum and about 14inches across so not to big for half inch in my opinion and there is a bolt pattern that is the tap size for 1/4 20 and I tapped two 180 degrees apart before I broke the on 1/4 20 tap I have. This is to replace the bent winky dinky thing in the center and I have a bushing that I will put in the center for it to spin freely I had it on a 3/16 shaft no problem at all the gear is really light and not getting lots of load so it will be fine.

This part is to do what the brass piece is doing to make it easy to get the teeth to mesh and make it work a lot better there will be barely any load on it so it is over constructed for the job.
