The saw did a good job cutting the gear wheel teeth.
Around that time I did have some thoughts about purchasing a scroll saw to add to my collection but put that out of my mind after the successful jigsaw project. Anyway…I did end up buying a scroll saw so I’m back playing around with wood gears some more.
Picking up from where I left off we need to sand the gear teeth - in some way?
I don’t want to sand them by hand, the results are likely to be inconsistent…and just to tedious. So I came up with the idea of wrapping a used jigsaw blade with sandpaper. Cut off a piece and smear with a glue stick, also apply same to the blade. Line paper up with back edge of blade and wrap tightly around one and a half times, apply more glue on the overlap and lightly clamp or weight down until dry – then trim off.
BTW: The blade that’s missing from the set is the ‘scroll saw’ jigsaw blade which of course is being used on the jigsaw table.
Moving on we now have the opportunity to use the scroll saw to cut out the spokes.
Mind you…I did do some test cutting after unpacking and setting up the saw.
This takes some patience as the blade obviously needs to be removed for each spoke, poked through the pilot hole and re-tensioned. The cloths peg is a reminder;
I always de-tension the band saws, and now also the scroll saw as well, so I clip the pegs onto the blades to remind me to tension up before use.
Finally I turned the gear wheel on a brill bit to evenly sand down the circumference - the tooth tips.
Cut another a set of ‘demo gears’ to check that all the steps I went through are reproducible and that the gears spin freely – they do.
This has been an interesting exercise and I feel a router lift project coming up.
