Hogging out on a shaper

Agree with Ady1's last remark about power hacksaw.

Used one for cutting full lengths into 2-3ft for the shop, it was slow, BUT so much easier on the muscles.

I did cut the frames for Mona using muscle power, but when done, immediately bought a vertical bandsaw as all that muscle exercise just not my scene.

Wish I had that bandsaw now, as it had the blade welder on it.

Those generic H/V bandsaws hadn't been invented then, it being the '70-'80s.

Don't know how I would manage without the H/V now, as muscles would go on strike if I even think about sawing through anything thicker than 1/4", and even then they need forcing.

Geoff - Call me namby pamby, but I'm past caring

The origional 6 x 4 HV band saw was designed in USA in the late 1940s/early 50s for Sears (I think), the design was passed on to Taiwan late 50s/ earl 60s. Atlas Clausing produce a similar machine.

Ah thanks Ian, forgot about that.

Wheren't available in SA at the time to my knowledge, hence my comment.

I would have bought one pronto if they where.

Where they universally available as today I wonder.

Geoff - Carport cleanup and re-organising after yesterday.

Well I had to get this billet chopped up and I wasn't going to work my shaper for 9 days again just for a slice of steel, so I returned to my old original lathe system

In the absence of a dedicated machine this is by far the least wear and tear on my equipment

The cut got nice and deep before any adjusting was needed and a slice dropped off after the third cut

Accuracy/straightness was medium

Then came the facing off on the lathe, to save me using the shaper

5% cobalt- failed

Cleveland mo-max M42- failed

WKE 45 cobalt (tuff stuff and hard to grind)- failed

They all flattened like cheap chinese HSS

It's kinda strange because it can be drilled quite easily with cheapo hss drills

Anyway, King Carbide came to my rescue, yet again, and is doing the necessary intermittent facing off on this job. Just got to watch the chips, oh boy are they hot

Oh and only one blade needed, this time it survived no problem

Eclipse hacksaw blades are fab-u-lous

The job took 9 days again, about 4 hours a day with minimal intervention on my part

btw The original hogging out job has been done, now got a 2nd big vice and made a little brother for mounting into the big vice for teeny bits

Shaping this steel with 5% cobalt was a doddle

No chance of facing it with 5% cobalt on the lathe though, not even close

Cracked it!

And here we have WKE45 hss cruising through this stuff down to the finishing skim phase, not a piece of carbide in sight and only one pre-job tool sharpening required

ooh I'm a happy bunny

Anyone care to guess how I did it?

Fed straight into the chuck.

I must have put the answer into another thread, twit

I put it on the backgear and the tuff HSS did a great job at slow speed, much better than high speed and no chipping issues that you can get with carbide

My first reaction was - he must have hell of a surface speed at that diameter...
