I have an old Delta J-21 six inch jointer. Are there spiral cutterheads that will work in it?

Look at You might be able to find it by model number. Otherwise, contact them to ask. Most likely, the answer is yes.

I searched web for Delta DJ-21 and didn’t find any such machine. DJ-20 was there though.

Also talk to Hermance machinery.

They make custom heads in Pennsylvania and they have specs on many common machines.
I had one made for a 16” jointer and will have another one made for my 24” I’m restoring.

They do a really nice job.

Been selling Byrd heads for longer than anyone and never heard of that model. The 6” that is a similar number is a DJ-15 which is the smaller version of the DJ-20. Most popular old model 6” is the 37-220.

Looking at some info there are J references after serial numbers but that is not the model number. you can check and try to match it up to a picture.

Thanks to all who responded. The Delta 6” model is 37-275X. It is no longer in production. Its manual includes the J-21 number.
