Thread: Is This Waldown Worth Buying?

Sounds good I will use the new motor.


jhovel the motor itself is fully encased, there are no holes that lead to the inside of the motor.

I contacted Powtran in China and they have recommend a VFD for this motor Model: PI9130A 0R7G3 it will cost me $185 Australian including postage. They seem very helpful and responsive to my questions.

Jimb0b thanks for the tip the wire wheel worked ok but was unable to remove the paint that and rust that was really dug in.

BobL - Thanks for the info about Tannic Acid looks to be a better alternative to critic acid.

Motor looks OK, a bit more power would be nice otherwise it complements the machine nicely in terms of "vintagness:

I have now disassembled the whole drill press.

I am now I working on polishing the smaller components.

This is the first piece that I have restored to my basic satisfaction.

Originally it had a few dings and pitting. The I left some of the pitting on the surface with the numbers as I did not want to abrade off the markings.

I removed the dings using a lapping plate and same wet and dry from 80 grit to 600 grit, then I polished with Autosol Metal Polish. Its not perfect in that there are some errant scratches so I am thinking of giving it a light buff with a buffing wheel using the bench grinder. There are a few minor dings on the very edge were the knurling starts, again I left them as I did not want to damage the knurling.

It took about 3 hours.

I used some kerosene to strip the grease off the spindle, I also removed the surface rust from the morse taper. However it would require a huge amount of abrasives to fully restore, however since the morse taper is broken I will need to replace it.

Jhovel was right, 2nd Morse Taper is broken that is why the nuts were inserted to hold the chuck. The problem is that the c-clip is broken, I had a look online on how to remove the C-clip and the methods are rather drastic involving grinding into the c-clip with an angle grinder, does anyone have a less dramatic solution? It looks like I will need to replace the morse taper and the chuck.

There is some damage to this component I do not know the name. One of the teeth has been badly chipped, others have minor chips, will this be bad enough to hinder my machine. Can this be replaced?

Last night I placed my order for the Powtran VFD, it should arrive end of this week I am told.

I also notice this, is this normal or bad? The tenons are not parallel. This holds one end of the quill spring.

Does anyone have any suggestions to my problems and questions from my previous post.

Here are photos of the disassembled drill press major components on the floor, with the smaller pieces on a makeshift table. I used kerosene to strip most of the grease off the parts however the cast iron head of the drill press is caked on with 50 years of grease I will need to get a proper degreaser and a wire brush to scrub the inside clean. The grease is mixed with metal shavings and I do not what them working there way into something critical.

I made progress on a few small components they are cleaning up nicely over the next few days I will have them finished. I have ordered a few Poly Strip Disk from Smith & Arrow to use with an angle grinder I am hoping that they will help me strip the paint and rust of the major components. I will also getting a few soft wheels and wire brush wheel for cleaning up the smaller components.
