    Default Workday - Tuesday 1/10 @ 6pm


    Not enough people on hand today to get a beam glued together but we finished all prep work needed before glue application. Scheduling a work day for Tuesday (1/10) @ 6:00 pm to do the glue up. We'll need 6 or more people to get it done; expect it to take 1.5-2 hours. Please let me know if you plan on coming!

    Also, planning on stretching more boards with the Illiniwek park staff this Thursday and will be ready for the final beam layup next weekend. Tentatively scheduling another work day Sunday 1/15 @ 12pm noon for the final beam.

    The next workday will be on Monday Jan. 16th at 6pm. Meeting at the Illiniwek workshop again to glue up the final beam (will need 6 people). Decided to move it to Monday since Sunday is prime riding time.

    Default Workday - Monday 1/16 @ 6pm




    On Tuesday we finished glue up of beam #2 (photos above).

    This morning the Illiniwek park staff and I stretched the last batch of boards for beam #3 and also removed beam #2 from the form. We still need to get these boards prepped/sanded for glue up. If anyone has a couple hours Sunday morning/afternoon let me know and we can work on it (only need 1-2 extra people for this). Planning to glue up the final beam on Monday 1/16 @ 6pm at the workshop and will again need at least 6 people to get it done. Please let me know if you will be there.

    By the end of next week we'll start milling the beams to final size and applying preservative (this may take a 1-2 weeks for all beams).

    We ran out of a key component of our epoxy system last week (can't do glue up without it) and the replacement batch was supposed to be delivered today. It didn't show up so I'll have to delay the glue up portion until it arrives. This may be Tues. or Wed. this week but I'm not sure yet. Will update when known.

    I still plan on being at the workshop at 6pm tonight to get boards prepped and do minor repairs to the glue up form. Won't need as many people as before; 2-3 more should be plenty.

    Finished glue up of the final beam Wed. Check out a timelapse of the process here: Beam Glue-up Timelapse

    Will be puling it off the form tomorrow with the Illiniwek staff and then tearing down the form to make room for final milling of the beams. May start applying preservative over the weekend if milling goes as planned... Once that is done, they will be ready to move to Dorrance. The ground will have to re-freeze before we can take them off road though.

    The beams are finished! Completed them over the weekend and will be ready to haul them to the park once we source a trailer. Currently checking into a couple leads on trailers but if you have a connection let me know. A low deck height for easy unloading would be great and a length of 30 feet would be necessary to comply with IL trailer overhang rules. The beams are 34'-8" long and total weight will be ~2100 lbs.

    Once on site, we'll have to wait until the ground refreezes to move them to the final resting place and it may be a while before that window opens. A wheeled dolly (like shown above) will be used to roll the beams down to the creek from a ridge line access road. This is a 700' distance through a gentle sloping valley with 60' of elevation drop (about 8% grade). Once at the site they will need to be lifted across a 30' ravine that is +10 feet deep. Come-alongs, ropes, and pulleys will get the job done here.

    Thanks to a local farmer with a huge trailer and skid steer we were able to get the beams moved to Dorrance last Saturday. Next step will be transporting them to the bridge site when the ground refreezes. The beams need to cross a swampy area on the dolly which is fully thawed and really soft right now. They're also green now from applying a wood preservative (copper naphthenate); it should fade to brown over time.

    Looks like the ground isn't going to freeze anytime soon so I'm planning a trial move of the beams this weekend to see if it's possible with the thawed ground. Goal is to get them staged near the bridge site and ready to move across the ravine on Feb. 25-26th.

    Meeting this Saturday (2/18) at 11:00 am at Dorrance. We'll be working from the clearing at the top of the fire road just north of the ball diamonds (see map below). If you arrive late, the main gate will be closed but unlocked. Please close it behind you if you drive up.

    The first task will be to clear a path (sawing out deadfall & removing brush) to haul the beams in. Then, loading a beam on the dolly and rolling it downhill into the ravine. We may also need to construct a temporary log causeway over a swampy area to get the dolly through.

    Tools/equipment that would be helpful:
    • Cable/Chain Hoist (we have one, could use another, needs to lift/lower 700lbs)
    • Tow Straps & Rope (working load of >700lbs)
    • Chainsaw with PPE (chaps, gloves, & eye protection at minimum per Ranger's orders)

    I'll also have a few rogue hoes & pruning saws available for clearing. A group of 5-6 people would be ideal. Let me know if you're coming.
