MadNick:
Afternoon,

Well I fitted the motor and got the wheels turning around :) I even managed to do a couple of test cuts on some HSS but there is, however, a problem.

All along this build I have discovered crooked and mixed threads, off-centre holes, badly fitting parts - its been a nightmare. I assume the two missing components are the best bits because everything else has been, er accuracy challenged.

I have now found out the spindle is running off-centre which makes the cup grinding wheel run off-balance and with a buckle in it. I could do away with the spindle and revert to the direct method against the Clarkey but I reckon it would take as long to make a new spindle as it would to make the pedastal required to get the Clarkey to the right height.

I need to do something but just havent decided what as yet...

Fergus OMore:
You have a reasonably true spindle in the Clarke. Making a pedestal is only a matter of building up squares of chip board and holding it down with a few long bolts from Wilkinsons!

Once you are making sharp tools, you can concentrate on either re-screwing or re-tapping or making new bits.

I suspect that a tiny sliver removed from some so called mating surfaces will work wonders.
Much of warped stuff is the inability to work accurately up to a shoulder. A removed whisker often transform what looks like a 'Thrupple Nut'

Attention to detail

Morning,

Quick update. Have fitted the Clarke just to get things going. I was spending too much time on the other spindle -

There is still a kick in the grinding face, however. I checked with the other wheel on both ends of the grinder - same issue, will have to manage with it for the meantime.

Amid a fanfare of golden bugles, flags and dusky maidens, I started making my inaugural tool yesterday. You know I mentioned the project had been bedevilled by a curse, well the curse has struck again - the pivot for the toolholder pulled clean out!

Ive had enough for the time being and need to make some progress with the chopper instead.

Enter the 7th Cavalry or whoever to rescue Custard :ddb:

One- I've suggested that his wheel needs dressing( leave the dusky maidens to be viewed)
Suggested that he bought a diamond dresser( not you Moma, sit down) but No, NO :loco:

So Ive told him to use a scrap carbide bit or lathe tool. Could be a crap carbide masonry drill.

Finish off with a bit of crap wheel.

As for the 'pulling out' well it's Titanic time and yet again-- rotten rivets.

Need this deaf old fart say more :coffee:???????????????????????????????????????????????

MadNick:
And this afternoon's efforts featured real achievement :ddb:

First I fixed the stripped thread. You can see the knackered thread in the above photo. Luckily the pivot was cut 1/4" or so too long so I simply cut a thread with a larger diameter on the shank for 1/4" or so, with a corresponding one to screw it into on the top table. I then Loctited it in place.

The grinding wheel was then dressed to get a nice flat, consistent surface and I set up the top table/tool holder parallel to it.

I then ground two 5 degree rake angles on a piece of HSS to make a start on the tool for my fly cutter. Of course there are a lot of small niggles to iron out but now im actually seeing some results there is more motivation to keep going. I certainly need to make some changes to the tilt angle indicator and clamp, fit rubber feet to the wooden base to stop it moving and fab up some kind of guard.

Very pleased :) - thank-you Norman.
