  • Felting a Hippopotamus

    What a wonderful piece. Congratulations.I may start a little more modestly but I have been wondering how to do large 3D shapes with needlefelt.Thanks for posting the instructions.

    I doubt that the stroke would be long-enough. You might try hand felting, limiting your stroke to that of the tattoo gun before modifying it.

  • You can make it safer by applying a sheet of adhesive plastic film that holds the shards together if it is broken.

    My experience with laminating paper is that you can dilute the glue a lot with water. It is not certain that the product will be stronger with full-strength glue because the excess will be harder to squeeze out as you roll the log. Dilution may also allow dipping of the pieces in glue, rather than painting the glue on, and this is sometimes more convenient..Ideally you want the paper, not the glue, providing the strength. Not only does the paper have more tensile strength than the glue, it is the paper we are trying to reuse, not the glue. I usually use PVA now although have used gelatin and starch glues in the past. PVA is more resistant to fungal and bacterial attack but the others are easier to make from reused material.If you have smaller pieces of paper you can glue a few layers of t…

Generally easier than layering the little pieces around the log directly.

    Great idea. We've been running repair workshops in fixed locations but having everything mobile would be helpful.Depending how much you need to carry, a bigger or smaller vehicle might be more suitable. Our stuff could fit easily onto a pedal-powered load carrier: a longbike or a trike because we mostly use handtools. Give it electric assist if necessary but there is no need to pine for a tuk-tuk.As Coby points out, the tuk-tuk is familiar and iconic in Mumbai but that is not the case in places outside of southern and southeast Asia. Other vehicles may have that status in your community. (VW Kombis used to be that in the US, for instance, although most are too old to be driven regularly now)

  • If they are identical gearhubs, that would give you a maximum of just five gears. Sad but so. There would be nine gear alternatives but four of them would be identical to other combinations. If you want to multiply gears, the ratio gaps on each need to be different.The bike is interesting but how rideable is it? How much under 50 Kg (a hundredweight/112 lbs or so) does it weigh?
