Kennet Tool and Cutter grinder
« on: March 07, 2012, 11:02:59 AM »
Afternoon,

Im really pleased to post this up as my new thread - ive been looking for a cutter/grinder solution for a while now.

I picked this lot up yesterday after winning the auction on eBay.

Its an incomplete Kennet. I have yet to sit down properly and work out what is needed - thanks to Norman's help the task should be a bit easier. I also found a website where one was built from scratch so im not without support on this.

I cant see rapid progress being made but Ill keep you updated nonetheless.

Castings -



Other bits -



Motor (I bought this out of the local paper for £15 - 1/4hp, 1440 rpm)

Thanks Nick- pleased to help!

The next question is a bit  odd- does anyone in the Newcastle upon Tyne area got the facility to copy my full size blue prints of this 'beastie'?

I simply cannot get my own plans onto my little scanner.

There are- or should be near enough 100 items. Nick has got a lot of the bits and it should be money for old rope -if full size drawings are there.

I'm ***edited to remove email address***  if you can help him.

Thanks

Norman

Just a quick off-topic note. I've edited Norman's message to remove his email address from public view, or rather, from the view of any spam-bots, to prevent him recieving a deluge of spam emails as a result.

Any member wishing to email another member can do so easily by clicking on the little "envelope" symbol below their avatar/picture on the left of the screen.(only registered members can thus see your email address) If you post up your email address (or worse still, your real address/phone number/ bank details) you are opening yourself up to a lot of spam and other nasty things, this is why you see Mod's editing messages to remove such details when they see them.



OK, back on topic now,

Bless you Norman - theres really no hurry though as I have plenty to get on with.

100 parts? Thats amazing - So far I believe I am missing 3 castings, amongst other items - Ill give laddo at MES a buzz tomorrow and see how much they are going to cost me.

I intend to get it put together and working before remaking some of the components, they are a bit ropey in places.

Thank you Rob but I'll await instructions from Nick!
Really, I was aiming at supplying Nick with  a 100% full scale check list. He could mark off what he's got and see what is left to either fabricate or simply machine. Most of the parts which had to come from castings are there but quite a lot could come from stock steel or cast iron.

Whatever it is- or whatever is going to be is interesting because some years ago I was talking to Arnold Throp at a Harrogate Show about Quorns and Kennets. He, like me, had made both. He was part or well connected with Model Engineering Services and was the Dore- In Dore-Westbury  milling machines. He used his Kennet every day whilst his Quorn lurked under the bench!

Regards

Norman

Nick,

I've had a look- sort of at your 'goodies'

Somehow, I guess that only a couple of important  bits 'might be missing'

Why not give me an e-mail with each bit on a separate photo. I'll identify each part and complete the Meccano set.

Whilst you are on-- get rid of that bloody awful electric motor. Chuck it at the neighbour's cat or the vicar-- but not anywhere near that machine.

( Hint, I'd have the bugger working by Sunday)

Norman you are so demanding!! Ill get some photos together tomorrow.

I know what you mean about the motor, it would be nice to get something more compact and svelte - I need to consider the options as the cutter base is the short version, there isnt enough room for that motor.

All you need is a 1/6th HP motor capable of 2880 rpm (or even 1440 rpm)

As the late Prof Chaddock said- a Cut of a thous is a BIG cut.

OK, use a 1/4 hp to 'rough out' lathe tools but if you want to see your dirty finger nails in the reflexion of a lathe tool---- well, you know the rest!

Despite what it looks like and probably what you paid, it is a delicate bit of kit.

I've downloaded a few bits from the main sheet- you now need shares in a sticky tape factory  :ddb:

Morning!

Yes, you have quadrupled my normal inbox content this morning!

Much appreciated and prefect for finding out what is needed.

re The motor your notes said a 1/4hp 1440rpm motor would suffice instead of a 1/6 and this one came up so...

Ill have a little look for something a bit more, 'delicate' (like me).

As you have a 'short wheel base' Kennet and mentioned getting it on the the smaller base, I sort of thought- 'ooh, err?'
Again, it isn't very protected from gr-gr- grit, is it?

OK,  change the pulley. Face East and - you know what to look for :clap:

You are getting there :beer:

Afternoon,

I made a quick start on the kennet. Thanks to Norman we were able to identify one of the table supports was missing.

I decided to have a crack at making one.

I hacked a chunk of this piece of old steel -



And spent the afternoon getting things square and clean -



Not much to report but its all progress :0

Oh dear, you are behind schedule!  :hammer:

OK, one bit of plate as a base- bore a hole in  the pillar thingy and away we go- laughin' and scratchin'   :beer:


This way you have a tool and cutter grinder working

Cheers

Morning!

I was busy last night, working on the missing table support. Thanks to Norman I was able to get an idea of the dimensions.

I turned my square block into -



To give you some idea -



Next I need to cut two slots into this piece, one to fix the pivot you see above, the other in which the pivot will slide.

Most impressed on how you have got on with only a bit of sketchy report in an e-mail etc to go on.

I am looking forward to it when it is 'all singing, all dancing' and doing the  things which it is capable of doing. :beer:

Afternoon,

Well so far so good. I milled the top slot out and then chain drilled the inner slot and cleaned it up with an end mill to produce -



Exude baby exude!



I tack welded the table support square to its base and balanced the whole thing together to give me encouragement to the project -



The table support base is located by way of pins and a clamp, I believe. These will be my next step.

By now, Nick should(  :doh:) have the drawing of the locating peg.

I'm going to need a Sabbatical after this  :bow:

Hi Nick, I hadn't realised that you had the spindle casting- hence my note about getting a 6"DE grinder.

Couple up that damned motor with a bit of round belting and let's see it- perform.

All that seems to be bugging the issue is the casting for the end mills etc- which I have-- and the odds and ends to do the saw sharpening.

Now for some smaller disks- eh?

Cheers

Afternoon,

Ive been busy.

The first thing to make was the sliding clamp for the table support. I came up with this -



And to give an idea of where it goes -



And then with the table support pillar that I made previously -



After that I made the lower part of the clamp thus -



Interesting I found the handle for this clamp was thread to an M6 whilst it should be a BSF as should all the other threads - more of that later.

With the sliding clamp fitted -



And then with the pillar put in place temporarily -



So, once young Fergus can tell me what the height of the original casting is I can fix mine to the slide.

Back to the threads. This collection of castings was the remnants of a Kennet someone had made previously. Needless to say there is plenty of room for improvement. Having nipped down to the toolshop and purchased some BSW taps and dies especially for this to clean up some of the threads I find out they dont match - when will I ever stop making assumptions. I whipped the thread gauge out which tells me that at least one of these is are a Whitworth 22G and the one on the sliding clamp handle is M6.

For the meantime Ill work with what I have as I want to get up and running plus there are more important things to make - holder for sharpening milling cutters.

I hope this post is of interest.

Nick

Ok,

Onto another piece of the jigsaw and another opportunity to turn rust into shiny steel.

I need to fab up a holder for collets so I can sharpen endmills. Thanks to Norman I have a good idea of what is needed. This attachment is similar to the holder for lathe tools so, just to get an idea of sizing, I turned this -



Into this -



I have to say the flycutter on the vertical mill is really good at this. It does need constant sharpening but really can level quite a large area in a short amount of time. Obviously once the grinder is up and running Ill be able to grind my own tool to the correct angles for the flycutter.

I just need to start sketching out some lines on the unformed block of steel and then putting some shape into it.
