Just picked up Delta DC380 planer. Unable to change feed rate cannot push in or pull out. Not sure if on 16 FPS or 30 FPS. Looking for advice on how to remedy. Can you tell from pic?
Thanks in advance

I believe you are supposed to change feed speeds while the planer is running. Have you tried that?

I had the 13” version of that planer (1982 vintage), and like it very much.

Yes I understand you can only change speed while it is running. Shaft will not move in or out.

+1 can only change speeds while running, but you can sometimes shift into neutral while not running.

Have same planer. My guess is shaft is bent. Has happened to mine.
The speed selector shafts are made from generic soft steel, and are easy to bend. They have a very close tolerance fit into gearbox, using an o-ring to seal shaft. Only takes a hard knee hit to the shaft to tweek it.

If turn on planer and look underneath at feed rollers, you can see if it’s in fast/neutral/slow. Total amount of shaft movement when shifting speeds is small, less than 1 inch total.

Black knob is threaded onto the speed shaft. Can remove knob and use straight edge to see where shaft is bent. Gentle persuasion with block of wood and hammer can straighten it enough to slide in/out. Do not twist the shaft as inside the gearbox there is shift fork attached to end of shaft with screw. If screw gets loose, the fork wobbles making it randomly shift into neutral, you will have to open the gear box and tighten it.

Best Luck.

Thanks for the informative response. I will give a look tonight and check straightness. Curious when looking underneath how I will know if feed rollers are turning at the slower speed or the higher speed?

I feel like an idiot now- I have a 16” machine of similar design and found out the hard way it apparently can go into neutral, I got it into a gear and left it alone, will have to try it while it’s running now! When I first fired mine up the feed rollers weren’t turning, I thought something was bad wrong lol

I am certain that you intended to say 16 or 30 feet per MINUTE, not FPS like it appears in your message. 30 feet per second would be pretty darn fast for a planer!

Why not run a board through and time it?

Yes FPM not FPS… :) Will do the board check.

I have taken apart and believe shaft straighten. Extremely tight, need to persuade with hammer and block to move either direction. Thoughts?

hmm,
Since you cracked open the gear box, have couple of options:
1) remove the shift fork from end, and completely remove the shaft.

-Check the o-ring seal. Might be damaged/dry and causing extra friction. Easy to replace. Can measure the shaft with calipers and find a replacement at any competent bearing shop. I remember finding my new o-ring in HF assortment. HF sells o-ring assortment boxes for $10 that can be cheaper than ordering OEM o-ring.

- If new o-ring doesn’t fix it. Can attempt to straighten the shaft on metal plate with soft faced hammer. I had to do that on mine. Work slow and don’t hit metal on metal or you might elongate shaft and make it worse. Clean off any rust with 400 or finer grit emery. If you find a high spot due a bend/kink that isn’t next to o-ring sealing area, can use a file to remove it.

- Can buy a new one. Renovo parts shows the shaft is still available for ~$7, despite most other parts sources list it as special order with ridiculous long lead time. Renovo bought warehouses of spare parts from Delta when B&D bought them and started selling off old parts inventory to pay down debt. They have a lot of rare Delta stuff.

Best Luck.

PS – be very careful with gear shafts in that case. One of them has gear locked into place with ball bearings and small spring inside the shaft. If you slide the gear off the shaft and are not ready to catch the parts, the spring and ball bearings fly into outer space, never to be seen again. DAMHIK.

I am fairly certain shaft is straight. Worked on moving shaft back and forth many times, cleaned and lubricated shaft. Did not free it up at all. For now I put shaft in position for 16 FPM position and put all back together, and filled with new oil. It is now running on slow speed.

Based on info you gave me I am thinking I will get new shaft and O-rings and have on hand for next time I want to take her apart.

Curious as to how much you use the high speed?

Thanks for the help.

You would be surprised on how little deflection the shaft to hole tolerance allows. Part of challenge is length of casting bore that o-ring uses for sealing. I made couple of short strokes with bastard file to remove a 0.001 high spot on my selector shaft and it started sliding much easier.

- Golfisher

I switch speeds more often than I thought I would. Would guess use each speed about half time? A lot depends on wood type. Always use high speed running stack of lumber through first time to remove as milled surfaces. Straight grain boards will run at high speed and leave decent surface. But figured wood, or lumber with knots or grain changes can experience massive tear out (chunks) at high speed, even if you feed in right direction for most of wood. Use low speed and shallow cuts for less than perfect or special lumber.

Cheers!

I seldom use the high speed on mine. Bear in mind, I’m a hobbyist and never in a hurry but the bigger factor may be that the speed control is on the inboard side of my planer (they way it sits now) and not all the easy to reach; so I just leave it on the slow speed. That said, I doubt I would switch it back and forth much even if I could reach it easily.

Another question, see pic. Went to replace knives on the unit using a Planer Pal magnetic knife setting jig that I purchased. It does not work on this planer as the jig is too wide. Cannot get both sides of jig down to the cutterhead. First I hope I can return the jig. Secondly is anyone aware of a more compact jig that would work on the DC380?
Thanks
Jeff
