Made a start on the spindle . I'm not going down the thick wall pipe/tube route . I laid my hands on a chunk of stainless steel of some sort (looks like it was an old roller ) because it has a 1" bore (handy) so I turned it down to press fit inside the the 3" pipe I'm using plus epoxy glue .

I have a question ,I have two tapered roller bearings . One's a Timken slightly smaller 56 mm od but a better quality bearing than the other one which is 62 mm od .Will it matter if I put the Timken on the bottom ..

I'm so glad I'm not the only one ,I'm terrible for overthinking things then I confuse myself

Sean

Rainbows no probs ....

Hi John ,

I've enough material to make another two which as you suggested will be a pair .

Sean

Thanks Trevor ,

That was my next move along with a slitting saw cut along the bottom of the vee .

Sean

Made myself a wee vee block and I'm planning a couple more out of the same piece of material . I also learned how important setting up a work piece up before machining . Also used a carbide end mill for the first time today (very impressive ) . I cut the square channel on the side using a 4 flute ,is this good practice or should I have used a 2/3 flute . Overall I'm happy with the end result . The Centec2 keeps on impressing ,I was taking what I thought were big cuts for this small mill ,the only thing stopping taking bigger cuts was the operator .

Getting a tad impatient now to get the vertical up and running .

Don't know why my photos are always like this on here ....

Thanks Rainbows ,I have quality bearings ,the biggest has an od of 62mm and the smaller has an od of 55mm I think .I don't think 4mm is enough meat I'd rather a bit more . I can't remember off hand what the capacity of 4 jaw is ,but the max capacity of 4 jaw will dictate how long my spindle will be .

This is what I'm planning ,hopefully with adjustment on the vertical axis .The collets I'll be using will be ER32 and MT2

I'm attempting to build a vertical head for my Centec2 horizontal mill . My thoughts are ,seeing as I'm going to all this trouble I might as well try and use beefy materials because for it's size the Centec 2 is a beefy little machine . For the spindle I'm planning 80mm od steel .I need to bore this out for the spindle bearings and draw bar . My question is , The round bar I'm using will be 80mm x 250mm long is this too much for a 6" 4 jaw ,I don't have any kind of steady rest . The through bore hole isn't critical ,but the seats for the bearings are and need to be bang on .

Sean

Result there Murray

Sean

Could you mill out the rectangular hole a bit wider on the narrowest side perhaps . Nice mill .

Sean

Thanks everyone ,most helpful information given . Just need to get going with this vertical head I'm in the middle of making . Dovetails cut today so some headway made .
