Emotional support machine. MVM 850

One day the boss storms up to me waving another sharpening invoice. He is very upset. How could I justify this cost ?
My answer. 
" How much did you say productivity has improved since I became foreman ? Over 100 % ? That's what it costs"
End of heated discussion. 

When I was an apprentice in the UK, most shops had their own straight knife grinder, especially the bigger joinery/ mill shops.
It was understood that quality control and accuracy relied on sharpening tooling regularly. Carbide saw blades were sent out of course. 
My uncle had his own favourite knife sharpener at his shop. " He's the only one who does it right". Very true.
Many sharpening services push the schedule on knife grinding and don't spark out the knives and hone them in pair's. 
Result ? Knives that aren't straight !
Very annoying. 
This machine took me ages to find. 24 years to be precise. Good grinders are very hard to find in Oz. The few that do become available are worn out. Beyond repair.
This beauty was a trade in. The dealer had tried to fix it and as usual he gave the job to someone who had no clue. So I got it for a song, stripped it down and fixed the carriage drive sprocket that had been reinstalled back to front. The bearings on the carriage needed adjusting to get rid of the rocking.
That's why the guy traded it in. It no longer worked properly on his insert knives etc.
Anyway.
Good as new now and big plus, it has a VFD for the feed carriage. 
Finally I can grind my own knives and be happy with the result every time. 
It came with a CBN cup grinder and diamond grinder for carbide. Plus a magnetic bed for insert knives. 
In the UK these machines are easily available used and reconditioned. 
Well worth the money if the price is right.
No more pushing the knives that bit longer.
No more tolerating inaccuracy creep.
Blunt knives are hard on machinery and operator. 
There is a chronic lack of know how in the wood trade. Dealers want to sell new machines only. End users often don't look after their gear and flog it until the lease expires I guess. The tax laws encourage this.
But their "loss" can be your gain.
