I am not convienced you have been screwed by Delta,
If the problem has happened before it may well have been caused by the person who is changing the blades for you on your Delta 37-190 6”

The fact you have to go buy a wrench is also a concern as its part of the equipment schedule and the fact that its missing also indicates that the blades have been incorrectly installed.

Your planer is no different to almost every other 6” planer available and the blade maintenance installation setting and change out will be almost the same regardless of the brand.

As indicated by the other LJs you could use anti seize on the screws, this is very good advice however doesnt help in the current task.

Planer blades should be installed using a torque wrench and this can be a simple as the length of the tool and using your judgement to ensure the bolts are all the same installation torque, or a “crows foot torque wrench if you can buy one.
there is documented evidence showing the effect of overtightening the screws in the head available on the net so if you havent seen the articles already.

There is also a table showing the recommended torque settings for various size bolts indicating both dry and lubricated, of which anti seize is.

I checked your operators manual and Delta do not include these figures in the service info, and thats a oversight by Delta in a big way.

The planer allthough not high volume use tool in the workshop in most cases needs to be ready to serve at a moments notice, so it may be worthwile spraying perserving oil on the cutter head after use to prevent any environmental issues effecting servicing. Dont be concerned about residue comtaminating material as the rotating speed will fling it off before you introduce your stock, if it dosent the cutters will remove it anyway.

A helical or spiral head.
You will not reget installing a new head the adjustment and set up time saved alone and piece of mind knowing that everything is perfectly aligned will impress along with the results of finish and loss of noise.

Conclusion: Torpedo 7 sells a small torque wrench suitable for your task but you will ave to buy a crowsfoot as well.

I hope you get your planer purring away soon let us all know how you go please, as having to take to it with a hack saw is not good!

Additional note: I also checked your profile I see you joined in 2013 but have never posted any projects, meaning you have never made anything to post either completed or as a Blog this usually warrants me deleting the reply but in this case there may be others who could benefit so I will leave it this time, .....get to work!
