Not only that, but she asked me to make a shrinkking machine to compact fourniture down to aircraft allowance limits :lol:
Build two different benches today. Still have to design a chair for me or :coffee:

Just about got sorted out with the garage conversion; got my 'toys' set up on their stands & levelled off as best as could, not having access to an engineers level used my magnetic DIY version & if I say so mesel' not too bad for my tired auld peepers.
Had to get a set of adjustable feet for the mill as my attempt to level of the floor was not 100% successful(first attempt at this sort of thing) & chinese stand fabrication left a lot to be desired,had sent one set of the lathe stands back with the lathe for an exchange as the lathe had a very poor manufacturing / Quality control problem, anyhow got it sorted.
A selection of photos for your perusal:

.. Will have to close off for now as photobucket new version is freezing up my pc :bang: will continue later.

Reverted back to original Photobucket..anyone else had similar probs with new version?..
Picked up a bargain from my local rag a few weeks back.. bargain at £35..mint condition apart from surface rust on table, soon cleaned off
New tools
Started tramming mill: ..
Level from front to back: taking into account my elderly eyesight.+ varifocal glasses, & allowing for paralax error..well! got to look for some excuse :) not done too bad methinks :thumbup:
New tools
..and from left to right
New tools
Set up centering device with 150mm finger on 3mm float glass after cleaninig table.. & glass. Dial calibrated in 0.01mm increments..zero at right of table
New tools
+ 0.005mm high at left of table..total swing 300mm.. looks good!
New tools
Zero at front of table.. with 50mm finger
New tools
..zero at rear
New tools
Double checked with DTI.. zero at right..
New tools
+0.001" high at left..could well be slight discrepancy on glass ?
New tools
Zero'd at front..
New tools
- 0.0005" at rear..close enough for me I don't think I need to tram it in any closer..if it aint b*****ed don't fix it I always say.
New tools.
video shot of indcator ..instructions tell you to run it at less than 500 rpm to give an overall view of any deviation:

Looking forward to creating swarf.. :clap:
Cheers

Very nicely/ painstakingly done George! :clap: :clap:
I love to see a virgin workshop. All ready to be swarfed........ :thumbup:
Showing great potential. What will you be making?

George,
Just couple of observations on the tramming shots using the Blake / co-axial centring indicator, especially for anyone who doesn't follow on with a conventional indicator sweep as you did.
The Blake indicator will certainly give a qualitative indication, but it may not be the best tool to use.
Tramming a mill using either a single plunger indicator on a displaced-centreline arm, or using a tramming rig (as Bogstandard's design) has the plunger operating in its designed axis, so, if desired, absolute readings can be taken.
With the Blake indicator, its great at showing qualitative differences, and centring by minimising the needle's oscillation, but I don't believe you can easily take absolute readings from it. At its heart, the centring indicator does use a graduated indicator mechanism, but the indicator arm has variable geometry, so the graduations are really only relative as you creep towards the centre 'it was +/- 20, now its +/- 1'.
Also .... when tramming, to get the maximum sensitivity, you want to measure at as great a radius from the spindle as you can. With a conventional spindle-mounted holder, this positions the indicator out at the extremity of the sweep. Using a long arm on the Blake, the longer the arm, the longer the lever outboard of the pivot and the greater the reduction in sensitivity, so you won't get the same benefit from taking a wide sweep.
