Scroll sawing into insanity

[Beave2012]

Any guesses what my weekend activities involve? Hint: although it looks like birdshot, it is not.

BTW I need a 20" throat on the drill press now. Lol had to hand drill the center.

Well I have spent many hours in the shop (ok garage, but at least now its heated!), and got the center of the main backer completed.

However, I must say I have done nothing but curse the spiral blades, not because of mistakes, but because of how fragile they are compared to the regular blades. I am using them however because I don't have to worry about the throat getting in the way during curves. I used the regular skip tooth blades most of the center, until I started hitting the throat, then swapped to spiral.

Additionally, during my scrolling hours I managed to break the spring in the scroll saw itself, and clogged up the air blower. So once the spring broke inside, I had to tear it apart (first time for everything), hope it was the spring I saw on the parts diagram, and then "repair" it and clean out the blower cylinder so that could work. All works fine, but slowed down progress. At least I know for next time how to open up the scroll saw, because this time I removed every bolt I could find, almost gave up, and then checked behind the "Shopsmith" stickers for the last 2 bolts.

Not to mention I went and oiled the headstock before starting, just for good measure. I just hope now that I can finish without having to disassemble any more tools.

I still hope to have the last of the frets done by the end of the week. With any luck, that should happen.

About 18 hours at the scroll Saw for this piece. 20 spiral blades, 2 headstock lubrications, a tear down of the saw, and cramped hands from a lot of blade changes.

I did feel as if I was dancing cutting the boarder without a spiral, so large to rotate without getting a workout.

2 shelves and finishing work left.

It looks great! What needed lubing?

I'm currently up to 451 individual cuts (449 inside cuts), and with the dial being turned to speed for around 400+ of those cuts, I blew out and lubed the sheeves. The motor was on for a long time and I thought lube was once every 5 hours runtime, so I did it to make the dial turn easier and, it was over due to be honest.

I misunderstood! I thought you meant you needed to lube the scroll saw!

Are you saying for every cut you turned the machine to slow., moved to the next cut and turned the machine up to speed? I would leave it set to the proper speed and just turn it off and on. When you are done with the current cutting session then turn it down to slow.

I know what SS says but I have always believed it was a safety/liability issue. By always turning it to slow you won't over speed an SPT and cause damage or injury. My shorty is used primarily as a sanding station. It has the disk on almost all the time. I leave it set on "G" which is the middle of the disk sanding range. "G" is also in the speed range of the belt sander and strip sander that are used on the same machine so no problem. And no it does not blow the circuit breaker at that speed.

Really nice job on the scroll sawing!

LOL, we'll yes I did turn it up and down every cut... I thought it was too keep it running well. If it's a safety issue, I could just buy a peddle for scroll sawing. My SS is on its own dedicated 30a breaker, so that's no issue.

My hands are sore from speed adjustments, wish I had known this earlier.

I have never encountered a problem with NOT turning the speed down in over a half century regardless of the operation. However I have a 230v motor(greatly reduced startup current). It has never been operated in a low house power location either.

At scroll saw speed/load I would not be concerned with lowering the speed between on/off cycles even with a 115v motor.

An indirect reason for the lowering speed at the end of the day(or prior to being moved) is that at high speed settings, the control sheave is open and the motor belt can potentially drop too low into the pulley and cause a belt jam.

And then there is the slow spt installed after a high speed operation 'issue'.
