.....How do you get a surface finish like this in the bores ? 

John S.

Tis the special lubricant they have up there - Newc'y Brown !  (even if the finish isn't any better, you can't focus on the fine detail!)

P.S. not casting any aspersions (or nasturtiums!) on Rob's sobriety in the least ....

Priceless but inaccurate.

Judging by his projects, I see no sign of ' clumsy ' ...

Evening Chaps


Had a good couple of afternoons in the shop ,, The welded assemblies  came out of the furnace black and crispy    ,, so they were given a quick blast .

Then they required truing up , as welded a assembly  always moves a tad  skimmed up on the mill/drill

Next onto the HZ mill to machine off the excess material , setting the table to 27.5 deg


Chamfers machined on with a 45 deg HZ cutter


Then onto the shaper to clean up the underside

They look even better in the flesh

Cheers Lads    thanks for looking in 


A bit of tooling required so that i can carry on with the build  ,, i need a box angle plate for a set up on the mill , when i got a new shaper I decided to recycle the old Alba shaper     i kept the table as it would make a cracking box angle plate .



I gave it a bit of a scrub up and checked it for square ,,,,,,,,,, then chopped of the excess material were it would have fitted on the ways.
Set up on the mill and the underside  was mill flat and true and a few slots milled into the bottom .



Next the closed end was milled and slotted

Couple of clamping shots .



Job done all bar some deburing 



I even have a use for the three tapped holes that were for the gib adjust screws ,,,,,,, just the job for fitting a fence 


Another job off the list and a dam handy bit of kit for an afternoons work

Didn't think there was much demand for box angle plates any more? Just weighed three in   

John S.

[Rob.Wilson]

You did what John 

Most of the ones i have seen on Ebay are either to large or go for over  £100 plus P&P .

Edit   Seems the euro is clobbered too unless you got here via 'Recent Posts', in which case it does work.

Far too clever for the likes of me ...

Working on it. Will look into it tomorrow...

BTW... looks OK in the reply box. Lets see how it posts

A wee bit more progress 

The 626 table mounted on the mill using my new box angle plate  so that a can redo the dowels that hold the table ends in position .


I had to use a second angle plate to give me a tad more room for clamping ,, the spring between the clamp and plate is there so that the clamp and packing would stay in position wile i lifted the 626 table into position .


I used a coaxial indicator to pick up the old dowel holes .


Then drilled and reamed for the 10mm dowels



Dowels fitted and i also drilled and tapped the nut fixings , I used a couple of roll pins to lock the nut ,roll pins need a trim .

Bloody magic rob

 

I just love cleaver set ups like that

Bloomin' good set up Rob!

Very clever
Be a handy tool that box angle plate

The 626 table mounted on the mill using my new box angle plate  so that a can redo the dowels that hold the table ends in position .

Oh, that looks familiar....  I couldn't use an extra angle plate for clamping though, I'd run out of table!




PS: Blimey, I just read this whole page, that's some really nice work you're doing there Rob! One day, I shall be at your level of skill (by which time, I'll be too old and infirm to use them doh!)

[arnoldb]

Good going Rob  - and nice setup picture on using that box angle plate 

 , Arnold

[Rob.Wilson]

Thanks lads   


Hi Ade  your job trumped mine ,, my drill was only 5 inches long  ,,,,,not 2 foot 

Managed to get the table ends fitted today , not allot to show .
But the method i used to locate the fixing holes may be of interest to someone 

I made up a couple of screw in transfer punches from a couple of 6mm screws

simply made by cutting the head off and turning a point on the cut end .

then two flats were filed on the end .

Then they are screwed into the holes using pointy nose pliers so the point is just proud .
 
The ends are then mounted on the dowels .

And with a tap from a soft mallet the points will mark the job were the holes require drilling .


I changed the fixings to M8 as M6 was a bit on the small side .
