Outdoor glue for deck railings

Resorcinol is no longer available in consumer quantities (I can still get enough to build an airplane). I need to glue some cedar 2x4s into longer pieces to repair my deck railing (the longest cedar 2x4 I could get was 8’). So, I’m going to do a scarf joint or something like it with a couple of step...

Re: Downdraft table - suction?

The vacuum won’t pull much volume. It’s suction will be unnoticeable if your table is more than a few inches square. You are right about the noise. Bigger fan, wider ducts means less noise. Have you considered a simple box fan? It pulls a lot of air. for illustration only: https://www.homedepot.com/...

Re: Doing fret board and head stock binding -questions

The one I use is homemade and about 18” long. Make another. Or, use two blocks that you already have. To make the clamping work on the neck, make a second tapered board that matches the fingerboard. Two straight boards on either side with the fingerboard on the neck on the bottom, a space, and then ...

Re: Doing fret board and head stock binding -questions

I glue the fretboard to the neck after it is slotted and radiused. I use the radius sanding block as a caul. It's easy that way and everything fits. I can't speak to the binding because I've never bound a fretboard (too much trouble to refret). I use the side of my preshaped fretboard as a guide for...

Re: Particle counters?

I have the Dylos DC-1100 Pro. It does .5 micron particles. When the count gets up, I put on a mask and turn on the air filter. I’m not sure you need exceptional accuracy (how would you calibrate?). But, you do need to know when there’s enough dust in the air to harm you. The count shows particles pe...

Re: Planning a workbench, any tips?

Make sure it’s really the right height for you. I work standing up and 38” is the right height for me (I used to be 6’ 2” before shrinking set in with age). The wrong height hurts your arms and your back.

Re: Shipping guitars safely

And one other relevant thing: I buy insurance from UPS because it’s pretty cheap and there’s no question on who has to pay, but my theft and damage policy for my business also covers (with a deductible) my instruments when they’re being shipped.

Re: Shipping guitars safely

I have used the StewMac system several times. So far, no problems. But, I never had any problems before I started using it either. Who told you that UPS and FEDEX required packing themselves? That may be true at the retail storefronts which are usually franchise businesses—packing is their business....

Re: Spanish style building repair?

Max, If you do want to avoid removing the back, I understand the old school way to reset a neck with a Spanish foot is to release the glue at the foot and for a couple inches on either side of the heel block, slip the block in until the neck angle is correct, and reglue it. Of course, this will requ...

Re: Advice Needed - When should I install frets onto my neck?

In the quest for a perfect fretboard, I’ve found that gluing the fretboard (I use hot hide glue) to the neck makes the perfect less perfect. After I glue the fretboard, I let the neck sit for 10 days or so to allow the moisture in the glue to work its way out. I attach the neck (mine are bolt-ons) t...

Re: Advice Needed - When should I install frets onto my neck?

I do it like Andy, frets before shaping. It’s easier. I do put the unshaped neck on the guitar and level the fretboard before I take it off and install the frets.

Re: water based finish over linseed oil

I don’t know the answer to EM6000 over linseed oil, but I wouldn’t do it because the linseed oil never really dries. I would expect adhesion problems. I use two coats of dewaxed shellac as a sealer and base coat before the EM6000. But, I do know the answer to brushing EM6000. I’ve done it many times...

Re: spray EM6000 in hot/humid condition?

I use EM6000 (and have since it was called PSL). My shop is kept at 40-42% humidity year round. I don’t like to set up the spray booth (which exhausts to the outside), so I spray outside whenever possible ( not raining and above 50 F outside) and immediately bring the guitar parts back into the humi...

Re: oscillating multi-tool saw...

Years ago, I bought the Harbor Freight one for about $30 figuring “how could they screw this up?” It worked just fine, but the handle vibration made it painful to use after a while. I replaced it with a Fein. Big difference in ease of use. The Fein was not without its problems—just out of warranty, ...

Re: Practice Wood - Archtop Tops and Backs

How about a spruce 2x8 or 2x10? Although it won’t be quartersawn, you can pick though the pile and find one with two 21” knot free sections.
