Back on the job, just. I've decamped to the house 'cause it's too cold in the garage and the reassembly of this secion is just too fiddly with freezing fingers.
First, however, a Drawing change. A mate called round at the weekend and was horrified at my Decimal Dimensions, so he changed nearly all of them to Fractions while I was making him a cup of tea. Fear not, nothing has actually changed, it's just the dimensions. However, it did dawn on me that while I've read many many old Drawings dimensioned in Fractions all machine tool dials I've seen were graduated in Decimals.
First step was to insert the spindle and re-attach the switch blocks. Apart from being extremely fiddley - it has to be done in situ - it was not difficult. I put a touch of Loctite on the threads just to be sure.
The next job was to re-install the Control Panel. The tricky bit here is to get the indent on the end of the Tuning Cap spindle into the pip on the panel. That took several goes, and some swearing, but eventually I got it back and screwed down. The vanes look pretty central so I'm hopeful that will be OK.
Next the knobs were re-installed - the Wavechange one clicks round nicely.
Now for the side panel and the coil box. Actually they were pretty strraightforward, again apart from a couple of very fiddly screws. The switch blocks appear to line up with the fingers. However, I'm still unconvinced about the 7 deg. offset on the square section as it really doesn't look to me as though it makes that much difference.
And that's about it for tonight. I have to re-install the other side panel and solder the wires back. Then it's over to the PSU and Speaker.
