Re: Dust collection?

Matthew, if I recall correctly, you're a part-time builder with limited shop space. I think you're ok with what you have if you set it up carefully, since you'll be running one machine at a time. If you look at Bill Pentz's site, you will see that effective dust collection can be achieved with a vac...

Re: LMI Temperature Controller for silicon blanket or DYI alternative?

Hmm, 100 volts? sounds like Japan. But $20 router speed controller should do nicely. Check Harbor Freight:

Re: Vacuum system

Just a couple of items. 1. Gast pumps can be rebuilt with kits that include the seals and reed valves. So if the motor runs and it doesn't look otherwise abused, then you can pick up a good quality pump cheap. 2. For laminating a neck, I think I'd place some small dowels in the interior laminations ...

Re: Vacuum system

also look for Gast pumps - many of these pumps are both vacuum and compression, with both single and double diaphragms. also, you might look for medical aspirator pumps - they come mounted and often with noise suppressors and bottles, and so they can be handy for other jobs

entertaining certainly, and maybe instructive about bending wood

This is far out of the guitarmaking orbit, but I think you'll find this interesting and instructive. You might have a look at making wheels for the borax wagons, too

no biggie: a good inexpensive glue syringe

Hi, Here's an item I picked up at the Kroger supermarket. It's a 30ml turkey injector syringe that has several features to recommend it. The barrel & plunger are made of polycarbonate, The needle & hub are standared stainless steel Luer-Lok fittings (medical style & grade). It can be fully disassemb...

Re: Adding set to a table saw blade

Just a thought - how about a half-circle paper or metal shim between the blade and arbor flange to add a tiny bit of wobble?

Re: Nut vise - another tool gets built

Looks good. Hmm, the handscrew in the background suggests that I might reshape the tips of one and use it for nut vise. It could be clamped in the regular bench vise.

Re: a-hum-won't-start motor with a complication?

There's always a wrinkle. The Grizzly part fit ok, but the motor wouldn't start. Annoyance>disassembly>check>reassembly>annoyance>disassembly>check>reassembly did not bring joy. It turned out the power switch broke (sigh), but I found a direct replacement nearby for $10 (and no shipping costs!). Eve...

Re: Holding device for an OM sound box for cleanup

Bob, I don't know if you saw the 'plumber special' positioner that I posted a year or so ago. I used two pipe flanges, a couple of unions, nipples, and elbows. One pipe flange was screwed to a baseboard, and the other to a platform for the guitar body. The platform was cut in the shape of the body, ...

The tech guy at Grizzly was extremely helpful. He found a switch that will work - $4.25 plus $9,95 shipping.

Re: Pantograph Logo Tool

Thanks. i've been thinking about how to do this and your experience will save time. For other work, i'm going to the technique of inkjet printing onto parchment (baking) or wax paper and transfer by rubbing, being sure to print the logo backwards.

Re: a-hum-won't-start motor with a complication?

Before I forget (again), the plastic collection bags for this 14" machine were unavailable locally, and they seemed a bit pricey anyway (5 per $18+shipping). I found that orangebox trash compactor bags work just fine at 30 bags for $10. I cut off the handle 'ears' and fold the excess neatly undernea...

Re: a-hum-won't-start motor with a complication?

Jet doesn't stock the parts any longer. The repair guy suggested a Grizzly part number for the entire switch, at $5 plus shipping. I'll give Grizzly a jingle to check that it will fit the arbor. I also measured the springs for the wire gauge, length, and number of turns, and then went to the hardwar...

Re: a-hum-won't-start motor with a complication?

The broken spring is the short one on the right shoe, and the fragment is in the jaws of the needlenose pliers. I'm happy it didn't drop into the motor. I spoke with Mr. Lloyd (mentioned above). He told me that finding the spring or brake would likely be very difficult and that Jet would be happy to...

Re: a-hum-won't-start motor with a complication?

After removal from the d/c body, I found that the centrifugal brake mechanism is fully exposed on the rear end of the motor. It was immediately obvious that one of the weights was cockeyed. A closer look revealed that one of the compression springs had broken. Although I was able to reseat the weigh...

Re: a-hum-won't-start motor with a complication?

Thanks much for the advice. Disassembly should provide at least a morning's entertainment. But before that, I suppose that I should separate the starter winding terminals and see if it has zero or infinite resistance, right? That will tell me if the contacts on the starter switch are closed or open....

Re: a-hum-won't-start motor with a complication?

Further testing with an ohmmeter shows that there is no communication between the motor winding's neutral terminal and the chassis/frame ground, and there is very low resistance on the windings. So I conclude that the neutral wire must have been in slight contact with the terminal screw, and when I ...
