« Part 2: Cold weather + Tight Bearings = fun Part 3 of Accu-Head Helical Head Replacement series Part 4: Done... finally »

So I managed to get the nut off the end of the old cutter head finally… I realized that my bench vise isn’t here and had to improvise a bit. Thankfully I had a pipe wrench handy and I wasn’t terribly concerned about mucking up the old head so I held it on the ground with the pipe wrench and used a pipe on the end of a ratchet to get the needed leverage.

Thinking I was home free I grabbed the pulley off… put it on the helical head… grabbed the nut that had given me so much trouble… and 1 turn in it bound up on the new head. I’m too tired today to mess with it but it almost looks like they got the thread pitch wrong on the Accu-head cutterhead. I checked a few times and it won’t go back about a half turn once the thread catches. Lovely. So tomorrow I guess I have to take a closer look and see what the heck I’m going to do about it. I’m about 99% sure I wasn’t crossthreading it because I tried it a few times so I’m a little less than pleased. That’s something that should be pretty easy to get right you’d think.

that sucks. are you sure the nut’s thread didn’t get messed up with the whole taking-out-the-cutterhead fiasca? if it did – I wouldn’t try to put it on the new cutterhead as it’ll only transfer the mess to that as well, and it can only go downhill from there.

stop, think, look closer, and find the troublesome part.

good luck.

Yea… definitely had to walk away from it. Truthfully nothing I did to get the nut off would have boogered up the threads I think. I checked and it threaded back on to the original cutterhead with no issues. Who knows…. Tomorrow is another day and I’ll see if I can get to the bottom of it then.

Have your say...
