No problem, if you want more pictures of anything in particular or dimensions, just let me know. Its right close in town- so its easy for me to get to.

If I was building one, I think I would cut a square notch in the drum and a key way in the chain sprocket that goes on the drum, and put a key in that clamped on sprocket.
That way it couldn't spin on the drum. If you cut a shallow squared off groove for the key in the drum, I don't think it would hurt the drum or effect how the cable spools.

I don't know that you would need a key. The clamping force will create quite a bit of friction. That can be easily fabricated as sprocket blanks of all sizes are readily available

I think mine needs a 30 tooth sprocket 160 pitch. On mine there are holes in the sides of the drum to both clamp and bolt to the flange(by the brake band) so it shouldn't need a key

Working at Laguna Beach/ aka. sewerage lagoons. We drove some piles for a small bridge. 16" pipe that was supposed to stop at 80' but barely stopped at 80'

You need to find a set of leads and hammer for your home cranes,im sure you could drive some pilings for something in your sand box .Heres some i drove at home with my 15B ,10" pipe leftovers ,H pile cap with exposed ag pre cast slabs for the deck. It seemed easier than poured coloms , but it was still a pile of work.

That's definitely quite the deck. If one the size I need shows up one day I'll definitely pick it up

Working on the p&h 430. All 4 bearings on the boom drum were shot. Chunks of bearing went though the planetary gear and chewed everything up. After I get the boom all put back together I'm installing power down on both drums

Be sure the boom hoist shaft isnt bent, I had a 325 tc with similar problems . We found a slight bend in the shaft ,most likely from the drum dog being thrown on at the wrong time.
