Tom Senior / Maho Vertical Mill Spindle Mod

[rhynardt]

This is the assembly "well rounded off"


Turned over


Fitted to the head with the flange attached

Next up i cut the piece of hollow axle for the horizontal hollowbar . Tough stuff indeed.


Gave the end a snug press fit into the flange it will be welded into


Had a friend weld up the assembly with 316 SS rods as he recommended it



Thats it for today. Tomorrow is another day

Some very nice work there. Definitely thinking outside the box, or as my Dad used to say " That's using your head for something other than a hat rack". Mike

dang, that's some impressive fabrication work!

Now if I grabbed a scrap counter and machined it, about halfway through I'd hit a void that was filled with sand and that's when
things would really start getting interesting...

Thanks Mike. Got to make do with what we have in this part of the world

I was quite astounded by the quality of the cast iron, not a single void in sight! Got a bit further this morning. Cleaned up the welded flange and trued up any warpage from the welding heat. Also bored the two pockets for the driveshaft bearings.



Did a testfit with the head assembly and it all looks good!



Things are going to slow down a bit now as we are moving cross border for a month to have my daughter born. Hopefully we can come back sooner and i can finish off this project

Hi All

Got back home earlier today with a beautifull noisy 2week old babygirl. Guess i should start looking for a shotgun....

Getting back to the Tom Senior-Maho marriage...

A fellow machinist friend decided to give me a surprise and complete the driveshaft and pillowblocks, ready to mount on the machine!
Herewith a couple of pics he took for me

Making of the driveshaft:





Next op the boring of the pillowblocks and the completed project:





Tomorrow morning i will go and fetch it and attempt to mount it. Once that is done i will have to figure out exactly how i will transfer drive to the head. I have a 1,2kw -3 phase motor and vfd already waiting for this job.

Will take plenty more pics tomorrow when setting up

Hi All
Got my Maho milling head mounted!!!

After endless power outages today in this brutal heat we are currently experiencing i threw in the towel as my workshop is like a oven when the ac doesnt run! So i got it mounted and left it there.

I lifted the whole assembly to see how it all fits on the mill body with a engine jack with a rope through the spindle





I then proceded to measure out the mounting holes for the pillowblocks, lay it out on the mill body and drilled the 12mm holes for the allencap bolts. Once that was done i bolted them on lightly so i could bed the horisontal arm straight and in line





Then i bedded the horisontal arm in the pillowblocks, tapped everything straight with my mallet and she seated very well!



Then i fastened the top of the pillowblocks to the bottoms and started to tighten all the bolts holding the assembly to the mill body



It looks like the business!!





Hopefully the power wants to remain stable tomorrow so i can get some work done

First congratulation's on your new baby girl.
Excellent modification very well documented.
We had a Senior M1 in the shop. Very stout machine.When my uncle / teacher passed he left me all the machines in the shop. Unfortunately the estate was in probate for 18 months so she doesn't look her best.
Here is a picture of her {We called her Gertie}
