Hav'nt posted for a long time so thought I would add my latest project. I bought a floor standing meddings drill some time ago with great intentions to repair, I don't even know what I will do with it when sorted as it's too fast an rpm (500rpm slowest) and too light duty for me anyway. Anyway, made a start yesterday. The head was frozen with rust where it is in the pic. The post is cast iron so it cleaned up not so badly
A good wire brushing and spray of Aldi's best GT85, then a few whacks on a piece of timber with a very FBH moved it, cleaned the rest of the post and removed the head.
Quill feed was also stuck solid, thought it was from rust and idleness but discovered that the shaft with the gear on it was bent, drill musta had a severe fall in it's time. So, didn't try heating as the gear might be a shrunk interference fit on the shaft, used the help of the press instead. Spin in the lathe chuck to check and it appears not bad, better anyway.
I would also have expected it to be steel too Seadog, but it's a grey like cast iron and sanding the top of the post with angle grinder produced dull red sparks, it strongly reminds me of cast iron.
I was thinking about fitting a bigger dia shaft with a no2 morse female taper but going to be too much trouble, so will just stick the drill back together when it's all freed up.
Thought I could remove the post from the base if I prised the lugs apart a little bit with a wedge, ohh lord!! Too much prising for cast iron. Don't think I would be allowed to print the words I called myself here. So.... Brazing a bit porous for some reason, it will be strong enough, I still couldn't move the post out of the base even after the heat etc.
Although the fella that sold me the drill showed me it running the motor wouldn't start for me, tripped the mcb. So a look at the wiring, ohh hell. Tidied it up a bit and added a washing machine cable.. Tried it and it tripped the mcb again. Will have a look inside.. The rotor was quite stiff to take out due to rusting, lot of corrosion on casings. Maybe going to need another motor. Cleaned and greased anyway, will reassemble and try it again tomorrow.
Plenty of electrical cleaner and elbowgerase then slow roast in an oven for a day or two, new bearings and she'll be good as new
Cleaned and now runs fine Reassembled and bit of paint here and there Just waiting for a new belt to come.
