Delta HD shaper question

[Tony Z]

I got a 60's vintage Delta HD shaper in a trade (along with a Holz power feeder). The spindle lock know does not lock the spindle. I tried a spindle lock from my Unisaw and it would not lock the spindle either.

Anyone here ever rebuild the spindle lock on this shaper?

Thanks in advance.

You're likely missing two of these:

Thanks for the info & posting a clear diagram.

Have you taken one apart and if so, what should I watch out for?

[Jonny Rocket]

Its been years since I took mine apart to rebuild it, but I would keep an eye on the fiber washers and where they go. I think if you look at the diagram, you'll see the casting has a notch in it and that's where you should find a collar with a set screw in it. You'll need to get that loose and I think the shaft will slide out the front after you remove the cover (part 60).

Many thanks!

that collar may have a taper pin in it or a roll pin. Mine has a roll pin I mistook for a setscrew.

I'm familiar with each from some amateur gunsmithing I do.

Thanks again.

this is where the plugs are inserted



here are the pins note the wear from use.



sorry for the bad pic but you will notice a black ring on the mounting stand It has two screws in it if you take the wheel off. You DO NOT have to remove this flange to repair the plugs. In fact you do not even have to remove the handscrew or the lock screw I do to clean up the lock screw only



To pull the shaft out remove the nut and washer on the end of the drive gear inside the shaper I did not take a pic that came out but you can tell it by location and in the pic below






shaft pulled out to access the pins



Next remove the plug pins ( I just use pliers to grab the one sticking out the furthest ) and remove them .



The pins after they are pulled :

You do not have to wait for new pins to arrive in your shop. You can still use the old ones for a while; I will order new ones next week for this shaper for replacement. In the mean time just turn the plugs 180° after you clean them up a bit adding a drop of oil to each one as you re install them
push the shaft back into the unit until you feel resistance against the gear then turn the wheel and push inward There is a washer on the inside and the outside of the end shaft so make sure you install the inboard one before seating it all the way. Most likely the bushing and the gear will rotate in place but the shaft will still be not all the way home. I just push until I can get the nut back on then tighten the nut to draw the shaft in place. If you did this without the second washer in place remove the nut and add it in now. tighten the nut securely but not excessively

At this point I put a drop of oil on the gears and from the top the elevation screw ( the vertical shaft) after I blow out any sawdust chips that tend to land in this hole when the shaft is near the top of the travel of the spindle

Run the spindle up and down a time or two to distribute the lube

Lastly I clean the threads on the locking knob add a drop of oil there and reinstall it. When I first feel resistance I move the knob in while spinning the handwheel until it stops. Then release the knob, run the handwheel up or down a ways.

That should do it. Now after you set the elevation and lock the knob the pins should set tight with little more than maybe 1/16 turn past snug . That is how little it takes to make the pins function. the ones in my shaper have not been replaced since I have owned it and my now gone help always seems to believe that tighter is more better. As you will be able to see once you do yours it does not.

Well, I examined the shaper this morning and I suspect the previous owner "tried" to fix the thing, but had two left hands. I don't have time at the moment, but this will turn into a full tear down.

My shaper is the earlier model, than Joe showed in his pictures, with a cast housing around the spindle lock mechanism. The roll pin is easily accessible, but someone previously mangled both sides. Reaching under the drive gear, it appears the nut and washer are missing!

So, I suppose I'll need to get a chum to help me flip the shaper over on its table and remove the cabinet to get at the innards. From studying the diagram from earlier in this thread, repairs should be doable, even if I have to fabricate a few parts. Just one of those situations where it looks like someone tried to fix something before learning how to fix it.

[Jonny Rocket]

I don't think there is a nut and washer on the early model. That collar with the roll pin retains the shaft.
