Equipment

We have one of the most well-equipped laboratories for dendrochronological research anywhere in the world. We have over 100 high-quality (and working) increment borers of all sizes (some reserved for teaching), a high-tech WinDendro measuring system, 6 chain saws, 4 Velmex measuring systems, 15 Pentium PCs, 26 stereozoom microscopes, wireless access to our in-lab laser printers, shop tools, GPS units, belt sanders, and digital cameras, along with all necessary field and laboratory equipment. With this arsenal of equipment, we can guarantee that no student, faculty member, or researcher will ever have to pay for any expensive equipment out of pocket! Throughout our lab, students have plenty of storage space for files and wood (via 15 file cabinets) and plenty of shelves and wall-based wood cabinets for wood being processed and measured, equipment storage, and document archival.

Measuring Workstation 1
WinDendro Scanner-based Measurement System

Former LTRS member Grant Harley demonstrates the WinDendro system.

We're very proud of our dedicated state-of-the-art WinDendro scanner-based measuring and crossdating system. This system has significantly improved our ability to rapidly measure tree-ring widths (earlywood width, latewood width, and total ring width) on multiple cores (at once) and cross sections. The software is coupled with distortion-free Epson 10000 XL flatbed scanner (which can accommodate very large cross sections), dual 19" screens, and a PC with 6 Gb of memory and a 3 Terabyte hard drive (needed for the very large files generated by the system), backed up by an external 3 Terabyte hard drive.

Measuring Workstations 2 and 3
Velmex Measurement Systems

Former LTRS member Mark Spond demonstrates the video-based measuring system.

We're also very proud of our dedicated video-based Velmex measuring system, which continues to be a workhorse in our lab. This system helps significantly reduce eye strain and improves our ability to conduct research and teaching about tree rings. The system features a Fisher trinocular stereozoom boom-arm microscope with 7-35X continuous zoom, Sony high-resolution color video camera, 24" Velmex measuring stage (0.001 mm resolution), Measure J2X Java-based measurement software, a fiber optic dual gooseneck illuminator, and a 21" Toshiba high-resolution color monitor, all coupled with a Dell Optiplex PC. Just to make sure there's never a bottleneck for measuring (and we have a lot of projects underway at any one time), we haveone more 36" Velmex measuring system workstation.

Field Equipment

We're proud to say (and we're being serious) that our list of field equipment rivals that of any tree-ring lab in the world. We have over 100 increment borers ranging in size from 6" to 28", and this includes many workable Djos borers (thank you, eBay). Our workhorse borers are the 16" and 20" 3-thread 4.3 mm diameter Haglof borers, and we have many spare parts (again, thank you eBay) including extra handles, extractors, and borer shafts. We also have (in case you need them) two 16" borers with 10 mm diameters for extracting large cores for isotope analysis (yes, these were special order and very expensive). We also have several specially-built 10 mm archaeological drill bits 10" in length for coring timbers from historical structures!

If coring trees isn't needed for your intended research, no fear -- we have six chain saws, including the older and more reliable Stihl 044s and a more modern Stihl 410 (all with 24" bars), two Stihl 250s with 20 inch bars, and even a Ryobi 18V battery-powered chain saw. We have a large number of chaps (in various sizes), many helmets (with ear protectors and face shields), plenty of extra chains, files, air filters, gas and oil containers, even an Oregon chain sharpener so we can sharpen chains in-house.

But it doesn't stop there! We also have several Garmin GPS units, a 20 ft diameter base camp tent, twenty 30 m and 50 m ground tapes, enough paper straws to last for 20 years, Coleman stoves, dbh tapes, Suunto compasses and clinometers, two-person crosscut saws, and plenty of map tubes (for carrying straw), aluminum clipboards, commercial plastic wrap (for wrapping cross sections in the field), several cruiser frame packs, borer sharpening kits and gun cleaning kits, and tons of biodegradable flagging in various colors! Once in the lab, we have several thousand feet of wooden core mounts (for both increment cores and archaeological cores), plenty of 0.25" thick mounting boards for cross sections, about 20 gallons of Elmer's glue and wood glue and masking tape, all for mounting cores and preparing cross sections. Note: any student who wishes to work in my lab will never have to worry about purchasing any equipment or supplies. Ever. That's my promise.

Finally... Wood Shop Equipment!

Our wood shop is one of the best! We have a Delta 20" floor-standing industrial band saw (14" height with 24" depth), a Delta 8" table-mounted drill press, four Makita 4" X 24" belt sanders and two Porter-Cable orbital hand sanders, a 6" X 36" table-mounted Porter-Cable belt sander, DeWalt and Makita variable speed power drills, two DeWalt 18-volt cordless drills (and chargers), a Delta 24" X 24" sanding table and vacuum system, Shop-Vac heavy-duty vacuuming system, a Fisher fireproof cabinet (requred by the university for storing all chain saws, gas cans, and chemicals), a Craftsman roll-away tool box (with Craftsman wrench, Allen wrench, socket, and screwdriver sets), Craftsman air compressor, Delta 6" bench grinder, Craftsman shop vise, tons of 4" X 24" and 6" X 36" sanding belts (all sizes from 24 grit up to 400 grit), lots of belt cleaners, finishing film (800, 1200, 1600 grit, for fine sanding), Delta floor-mounted industrial dust collection system coupled with a Delta ceiling-mounted dust microfiltration system, and 8 ft and 10 ft step ladders!
