I need a spigot spacer making. I have a bearing which fits the crank tunnel with an internal dimension of 17mm (as best I can measure with a vernier,
Dont have in internal mic)
The input shaft of the box Im usin measures 11.45mm using a micrometer.
The bearing is 10mm thick.
So Im looking for a space to take up the gap. Not sure on the most appropriate material, I guess bronze but steel would also probably be fine.
A slight bevel on the edges would also be handy for pressing it in.
Anyone handy with a lathe and fancy helping me out? Drop me a u2u and let me know!
Cheers
I could, but the problem would be getting the internal 11.45 imo. Thats an odd size even converted to " 0.45.
Are there any numbers on the bearing you're going to use? It'll be a fairly standard bearing & if the number is known then the specs
& size will be available somewhere to confirm your measurement. Chances are it is spot on 17mm, it'll be a metric bearing & they tend to
be made to round figure like 17mm & not 16.85 or 17.1.
I have a lathe but I'm not the most talented of operators & hav'nt anything other than a boring bar to make an accurate internal cut
& non of mine are that small.

its a standard 6003 bearing 35x17x10 so it should be exactly 17mm.
The inside diameter I suspect was 12 bang on (input shaft on a getrag gearbox) but after a little corrosion and a cleanup with emery paper is now a
few thou under.
Id prefer a snug fit in the bearing and loose in the shaft tho so 17 and 12 exactly should do fine 
Here's a good start

I could finish one off to your requirements.
good spot, bid on those!
Right, i won the bushes on ebay so I can arrange postage to someone if they want to do this for me.

dxf available if required.
An interference fit into the bearing would be great, and given its a mass made precision part Id assume its 17 exactly so Im not sure what normal
procedure is? Couple of thou oversize and then freeze it to fit or what?
Cheers
