Thread: All hail the shaper gods!!

Hi Ewan,
it sounds to me like the outrigger journal bearing has a tapered bore and the sleeve is tapered to match. The nut pulls the two tapers together. The sleeve should have a split in it along its length. Loosen the nut and knock the sleeve back or the bearing forward towards the end of the shaft (preferred) and that should loosen the sleeve and bearing from the shaft.
Thats what it sounds like. Of course I could be wrong.

Phil

Thanks Phil,
Yes the sleeve is split, i'll have to knock the sleeve back as i can't get to the other side of the bearing. I'll try that and see how i go.

Ewan

Thanks again Phil,
You where right, the bearing ID is tapered. Next problem is i need a new bearing as the outer race was either already cracked or got cracked in the process of removal. Its a FAG bearing, tandem ball, the races are just slightly concave. It has inner and outer race numbers (like P208 and P507 or similar) but no other numbers. I hope i can find a replacement without going to the cost of replacing the sleeve etc.
Now for the pulley....

Ewan

Well done Ewan,
the fun part is putting the new one back on. They can be a little tricky. With regard to availability, the hard part will be putting up with the looks when you ask for an imperial bearing size (assuming it's imperial). I get them all the time for line shafting at work. I find it better to get a new sleeve as well. The square headed bolt you mention is called a 'Hard Point' and I have seen grubscrews under these as well so "check check and double check". Also make sure there are no other hard points or grub screws at different points on the pulley. It's amazing how much pressure one small grub screw will hold, that is of course until you start running the pulley and for some reason they just come loose, hence the second grubscrew as a lock nut.
Remember, "check check and double check"
Good luck.

The bearing is metric! I don't know when the box was put on the machine, whether it was run off a line shaft for some time then changed over, or it came with the box, and the journal was replaced later. The box has imperial gears and shafts. I did finds this stamping on the box, seems to me like a date, but i would have thought it too early for a box like this, but i don't really know, anyone like to take a guess? If it is a date, it would seem i have a rough build date for the machine.

Hi,
I pulled everything else apart today, ready for one last dirty session with the angle grinder and wire wheel. I found a few more fixes, some babit bearings poured for the knee rise and fall shafts and a pretty nasty break in the casting that moves the crank end of the feed ratchet arm (does that make sense?) It has been repaired pretty well already.

I also found these strange diagonal scratch marks on some of the bearing surfaces...... i managed to get them to show up in a few pics

I am lucky to not have to and i pray to the shaper gods that i never have to replace the cross feed screw or nut. It is a twin lead square, not ACME 1/2" pitch......

Ewan

They might be the from the milling or scraping of the ways.

Yeah, they are scrape marks......it put a nice smile on my face when i found them
I don't know if they are original. By the looks of how much work she seems to have done i'd say not, but who knows......

The rise and fall screw is also telescopic like the one on your "new" horizontal mill

Ewan

I would say it was rebuilt a time or 2 in it's life.

That mill is not new, I bought it a few years back but only found a few photos of it when I was looking for something else, so thought I would ask here what brand it was. I have another one as well that I have had for around 15 20 years, but it's only a little one.

You have got yourself in deep with this one.

Dave

I'm sure the shaper Gods will be smiling , seeing how it's coming along Ueee

Forward ho, carry on and all that, eh what

Cheers.

I'm getting there......this evening was pretty productive.

I found another 3 taper pins that needed replacing, so they are now done. I left the lathe as it was but gave myself more tool overhang and was able to use the tailstock for most of the cut. Next time i will cut them small end at the chuck though.

I have also painted the knee, inside the table and the table support.

Then i cut some oil grooves in the two bearings i made with the dremel and a cut off wheel.

I also pinched Blondies lead and tested the motor....two thumbs up from me

Hopefully i'll get the rest of the parts stripped tomorrow....without destroying another angle grinder!

a pin that needed replaced...not sure how that happened, its out of the cross feed shaft



mmmmm grey paint.....smell those fumes.....



bearings...

Ueee I'd like to lock you in my shed for a few weeks, maybe my shaper would see some progress then

Done deal, now if you could explain to SWMBO......

Just a pic of the knee rise and fall i got together tonight. The gears seem to be cast iron, and the large one even has the machines serial # stamped in it, not the small one though, could be a remake, they both look like i'm not the first one to file them. I'll need to make a guard to stop any chips from getting into them, the gears were completely jammed with chips when i got her.

It really makes you wonder why they never cover the gears, I think just about every shaper cops chips in the knee gears.
