Thread: Tom Senior M1 Vertical Head Drawing
12/10/2019 08:40:26

If I remember rightly the horizontal drive has bronze or oilite? bearings & the MT shaft has 2 bearings in it. 1 at the bottom which is held in place with the cover & the one at the top is held in place with a split screwed washer (the type you put a screw in so it doesn't come loose I don't know what you call them) there are no shims in there. You have to put the bearings on the shaft first and then slide the whole thing into the head.

your old bearings should have numbers etched onto them so you can identify them like that if all else fails

Hiya John

Yes I am up to issue 4620 but awaiting some cast iron. 60 Dia mm as far as I can see you can't get it out of 50mm.

You can get the cylinder out of 50mm bar, just don't put the hole through the middle like I did in the first one sad

Hi all

I'm wanting to drill 3 holes in a triangular fashion on my mill with the PCD function I've already set up the work piece with the quill in the centre, The centre of the holes are 65mm equally distant apart from each other. Question is how do I calculate the diameter of the circle needed? I could do it on paper with a compass etc but I want it more accurate than that. I've had a look at the machinery's manual but cannot seem to find anything.

thanks in advance for any help

Hiya Ifoggy

yes it's a great book, I borrowed this from the listening library a while ago, not just about engineering though.

well worth a read

peak4 beat me to it, the bedroom work shop is an excellent site, there is drawings for the universal head on there as well as the fingers. You could use the er collet system to hold the drills as I'm planning on doing.

Iv'e never cut a cylinder from bar stock before, but seemingly "the process may look a bit daunting" crying

but "the process is quite simple"surprise not for me!

he goes-



cut a hole


oh dear! port face won't be big enough

start again




port face big enough yes



Ok it's not perfect port face is 0.2mm too wide and if you look close iv'e nicked the inside of the bottom flange, but that will be covered any how. so on the whole to say I've never done this before i'm quite pleased with the results, I'm going to leave the holes for the steam chest till later when I decide weather to make the chest 0.2mm wider or not. the exhaust is drilled but not tapped yet, a bit of fettling, honing and jobs a good un.

cheers Jason yes

Thread: Why does the micrometer have a second knurled segment

Photo finish Paul, let’s call it a draw

nah you win by exactly 60 seconds

The second knurled grip is designed to afford the user better purchase when using the micrometer as a hammer during squaring operations and such like.

well you learn something new every day, I didn't know you could use them as a hammer as well. I just use mine as a G cramp!surprise

Hello Ivan

Iv'e been following this and another post with some interest as I'm considering having a "dabble" myself.

with regards to Fusion 360 I know it's free for hobby users but for how long? Admittedly I have not contacted them but I just get the sneaky feeling it's just for 12 months?

Also you say that drawings are saved in the cloud. which I didn't know, does this mean you cannot save it elsewhere eg usb stick?

Is it possible to load it onto a computer not connected to the internet?

Iv'e been watching Paul McWhorter on the tube and i'm leaning towards Fusion 360 it seems doable to mesurprise

Hope you don't mind me asking

dia of wheel is 22.31mm length is 19.21mm

the boss is 38.5mm wide & 38.13 high

the arm casting is 111.2mm long it is fixed to the vertical via a grub screw to enable adjustment.

a 12.7 mm bar fits into this casting which is a total of 141.18mm long of which the last inch is turned down to 6.63mm for the guide wheel, which in turn is held in place by way of a washer & split pin

The amount of offset is approx 13mm

Hiya Colin

This is my filer although its branded a new wonder it looks the same, interestingly the top support in pic 1 & 3 is different but I have another support in pic 3 which fits as well.

I assume it's this what you require the measurements of? if so let me know and I will take some more pics of the part and some measurements

yes I agree with a lot of what the forum members are saying BUT,

I had nothing when I was a kid.

I know what is right and what is wrong.

I chose which path I traveled down.
