I have started on the bearings and after drilling the holes they will be sawn off and turned to width in the Unit lathe using the SC4 jaw chuck ...I will make the other jig to clean up the profile make the look more the part although they are nit split bearings as per the instructions

making the jig for profiling the bearings and 12 of these to make ..also I need to make a jig to hold them in place to drill and tap 10BA to join them to the  yokes / forks .....................

I have made the jig for attaching the bearings to the forks and have tried it out but it needs a few adjustments ...so..im waiting for more metal and nuts and bolts ....

I have now made the first pair and I have got a different lamp to get better photos ...

Those look great!

Hi Willy, that looks really good. And when I think about how much work it would be to build the bearings in sections as well.

[steam guy willy]

Hi Chris and Michael , thanks for the comments and yes lots of work that helps with all the jigs that we spend time making ..I was at the Norwich model engineers today with some of the elder members of the crew from 20 years ago. the people sitting on the bogies combined ages were 849 ??? I am :the 3rd chap from the left. and the 5th person was born in 1925 ?!!

More work and I am using the new  LED lamp. I am using a small PROXON cross and topside to drill the holes in  these small components ..they are made from aluminium so I don't use it for milling !! just to position the parts.  I have been turning the parts  putting on the  curved potions  I use these two stops for the tool positions  one is a jubilee clip and the other side is a block of steel......I have also modified the digital calliper to use in the confines of the Unimatt lathe.

Interesting modification to the calipers - lots of times when that would be handy, getting in between parts and such. Did you use a grinder on that edge of the jaws?

[steam guy willy]

Hi Chris ...yes  I did use
an angle grinder and I do have quite a few of these to modify. and it dosn't ruin the electronics !! I have used them on other equipment by drilling holes in them
cheers

All the eccentric rods are done and the 30 10 BA bolt holes were tapped successfully ..I use this large handled tap holder for these and I push the tap when turning it. I hold both parts in my hands...
