Hey Ian! Yep.. I've done a few JK bumpers. Don't really have a "production" JK bumper yet but I've got most of the parts in CAD to knock one out on the vehicle in a day or two.
As for the Shackles.. I use 3/4" Shackles from Northern. Rated at 6.5 Tons and have a 7/8" diameter pin. A 7/8" shackle has a 1" diameter pin but they'll bind in the clevis mount hole unless you clearance them with a die grinder. The pins usually have a "forging line" on them that interferes with the fit in the pin hole.
Hand is good. That liquid bandaid really worked well. I just kept it clean and brushed on the liquid bandaid a few times a day. I now keep a bottle of that stuff at the shop for all the little nicks/cuts that we get on our hands (almost daily). Now, I just need something for severe burns..
I mounted four QFs today on my tailgate rack and used the supplied plastic rectangle shaped washer to put the 10-32 screw through and they set up tight but I am wondering if it is strong enough and if anyone else has mounted them different or had any problems with that mount configuration?
The Qfs will be used to hold a shovel and a ax/max using two QFs each.
I probably wouldn't use them for the Baja 1000, but for normal wheeling, I think they're fine. If in doubt, you could run a zip tie around the center to clamp them tight.. not like you'd have to snip it off daily.
'80 CJ5 w/AMC360, T176, D44 w/Detroit 4.56, RE 4" YJ lift and 35s..
1/4" would feel more secure to me too. For now I will crisscross zip tie it. When it is all done, the swing out will close up pretty close to it, so I think they will be contained even if an end cuts loose or something like that.
I did get the rack done today. It is step one of the bumper build. The swing out will have two 5gl cans and a (rubicon) rack over the tire. The tire is a 33" but still adding lots of weight back there. I may have to get some Ground pounder fab 6" ctr boomerang shackles to compensate for the sag in the back!
