Thread: Adventures with cast iron - a wood plane.

Bob...do you have sketch ...err i mean detailed drawing of that tail stock?

I want to try and copy it...why draw my own if I can pinch some one else's plan

+2. I meant to mention this earlier. I'd like a little tailstock like that for my dividing head.

O.K. I will come up with a drawing or two. Bear in mind that the little tailstock suits the Hercus dividing head. It is adjustable. The angle of the spindle ( or centre ) can be altered along with the height.

This was the most complex piece of milling I have undertaken. I will start a new thread rather than bury it here. I will post photos of the process along with a few of the thing dismantled.

the latter two said they would gladly pay for theirs and mine Bob

AB, still drifting off topic, was the Hercus dividing head you spoke of the genuine article, or did you knock it up yourself. Where can these be obtained?

I reckon I saw somewhere some Hercus dividing heads partly complete. From memory, all the castings were done plus machined components. All that was required was some fasteners etc to finish them off.

Anyone see this, or was I dreaming?

Sounds good to me.


Wait! What?

Sorry Kenneth,
I had not read your last post because I was busy drawing the bloody tailstock
What you saw on Ebay were two Hercus rotary tables, one of which had the 6 inch table and base casting, the worm and it's eccentric spindle and the worm wheel. The other one offered for auction was only the base casting. The near complete table sold for $574. It would be interesting to find out how the new owner deals with the 4 1/2 degrees per rotation of the worm spindle. The gear ratio is 80:1.

I might have answered the dividing head question elsewhere. I'll have a look.

I tackled the job of milling out the recess for the front "bun" handle this afternoon while the rest of you blokes were watching the F1 preamble and sipping alcohol.

Finally found a use for the 4 inch Vertex vise that came with my Hercus mill when I bought it all those years ago. I removed one of the jawplates enabling the block of cast iron to squeeze in. Ridding the vise of the swivel base just gave me enough room for the 1 1/2" endmill, then the 19mm slot drill.

It was the first time I've really used the travel stops that I made and blackened last year. The job would have been nightmarish had I not had them. As it was, I can see why blokes watch football or play with bits of wood on the weekend. 2 horsepower and a big cutter can result in things getting scary real quick. Had 3 scares, thank f.. . it has belt drive.

Still with you

The rear of the plane base is angled at around 27 1/2 degrees. This is required for the alignment of the handle fixing screw. This was an opportunity to use the universal table on the mill tilted to the correct angle.

Everything was going well until I was close to the scribed line on the base and realized it and the cut edge were not parallel. The base and therefore the table, were not horizontal in the X axis. When the table is in the normal horizontal position having it slightly rotated on the vertical axis is no big deal because I set the vise jaws parallel or square to the face of the vertical slideway. I set a DTI on the spindle and realigned the table with a hide mallet. All O.K.

That endmill does a nice job.

Coming along nicely BT. Now stop watching the racing and get back to work

Struth,

I like the way the mill table tilts over. Are all mills like this, and moreover, I wonder if my Arboga will do this? That's a very handy feature, providing it can be reset to perfectly horizontal.

I guess you would have to dial the table back in.

Ken

I cut out the mouth and started work on the 47 1/2 degree frog. I will cut it roughly to 45 degrees then deal with the other 2 1/2 in a more tenderly fashion. The problem of insufficient room came to the fore again. I will have to use progressively longer cutters to finish the frog. The 5/8" slot drill I used, was pushed up hard against the back of the chuck. The first cut was full depth, about 20mm. The table was at the bottom of it's travel. Tight.

The universal table can be moved across the face of the horizontal slide. A handy feature and one which I used today.

As KJ suggests, a lot of time is spent setting up with a dial indicator. It's a prick to set the vise dead on then realize you have to move it to give the cutter a bit of room. Live and learn.

BT

I see your back at it.
At least with the table like that the swarf falls away.
