I understand some of these "not sure" reactions ... but from practical experience Matthew has loaned out Workshop Heaven supplies to great effect ... I know he may have a "commercial interest" in this ... but on his "pass-around's" I've had bits of kit to play with that have been through half-a-dozen or a dozen others before me and have clearly been used, looked after and treated with respect by each and everyone.
Equally, I have experience of lending a bit of kit to another forum user who I've never met in person ... not a cheap item either ... put it in the post on trust ... it came back a while later clearly having been looked after in their workshop and in packing for posting back, the blade I had was used and shorter after proper re-sharpening, but it now had a new alternative blade as well ... thanks!
So ... clearly some bit's of heavy machinery need to stay in their workshops, and perhaps someone can turn something for a member without a lathe, or someone else can planer/thickness, scroll/band-saw or rout/spindle-mould an occasional piece ...
But equally, I wonder if more "specialised" things could be safely lent out ... an occasionally-used travisher or convex spokeshave for someone making something like a one-off chair seat, a locked mitre-joint or a decorative profile router bit for an occasional job, a toothed, high-angle (or otherwise unconventional profile) plane blade for a horrendously-grained piece of wood, a specialised jig for a particular task (commercial or shop-made), etc?
I, for instance, might find it incredibly valuable to borrow a vacuum pump and bag for a one-off laminating or veneering job ... if it worked out well I might go on to buy the proper kit for myself ... or might decide it wasn't some thing I wanted to do regularly and would avoid both the initial outlay and then the wasted dust-gathering or e-bay-flogging options ... and say if I damaged the bag through mishandling (say) I wouldn't dream of returning it without a new replacement ...
"Lending", "Passing-Around" or whatever ... I know (as a user) ... could be a "NO-NO" for many ... but actually, when you relax and think about it, could be just fine ... not for "treasures" or "everyday" items ... but for occasional, specialised, specific or the like ... take a chance maybe? And be rewarded in kind?
