Re: Reliable Hygrometer Calibration for the Luthier

This is the second one started by, and illustrated by Mario Proulx http://www.mimf.com/phpbb/viewtopic.php?f=12&t=1701&p=15571 It demonstrates a very simple dew point method to calculate the relative humidity.

Re: Respirator Trend Airshield

Yet another question. I currently have a half mask with 2 cartridge filters. I have PP3 filters (what it came with) and PP1 and PP2 are available. The PP3 seems very effective. For example I was doing a bit of french polishing today and I realized that I don't smell the alcohol through the mask so i...

Re: Respirator Trend Airshield

I have been considering that type of mask. Two questions about it. How bothersome is the fan? Obviously if you are using a router of something like that, the machine will be making a racket so the fan is irrelevant but it you are hand sanding for example, how noticeable is it? How do you find the we...

Re: Flamenco build details from the book

As you have close contact with Roy, you can quiz him about the Santos plan in his book. If I recall correctly, I don't have the book (or "the books") to hand, the text mentions both classical and flamenco builds. However, pre-WWII the guitars hadn't really diverged into two genres - there were just ...

Re: Bowed Back board

For the next one, two thoughts. 1) If the wood seems to have any tendency to warp, use that to your advantage. Brace to take advantage of any "natural" tendency. 2) Don't brace either top or back until you are ready to close up the box. I aim to get the box closed within 36 hours and quicker if I ca...

I am going to buy some sort of power respirator system. While enquiring about a 3M system, the supplier mentioned the PureLite Xstream Somewhat similar to the Trend type.

GMC current tools - opinions?

I came across GMC the other day - never heard of them before. A friend has a GMC 710W router/laminate trimmer.

Thanks guys.

The sissor jack is a new concept for me. Had a look at it over on stewmac. I have to admit I would be quite nervous cranking that up inside a lightly build guitar for the first time. I do have stewmac voucher at the moment. Hmmm

Assume you have a guitar with a cracked top due to humidity issues (winter, central heating, icy weather, the white stuff on the ground etc). After humidifying for a few days the crack is almost visible and as tight as a tight thing. Do you have a strategy for getting glue in? Would cleating alone b...
