Actually, the device is already out there in another field. Pinging is listening for a specific frequency or tone. In music, there are meters to tune instruments and visually watch when you hit that musical note. Nothing more than having someone use a tuning meter and find the frequency that the blade pings at. Then anyone could use a meter to tune their own blade at the same frequency. Coming from Electronics design field a microprocessor could be programmed with that frequency and 3 lights with high, low and on tone light, or a digital meter to bring to a mark. In engineering its to design to the easiest first. Tuning meters are sold nationwide. The only secret to be discovered is the frequency of a tuned scrollsaw blade, maybe for each brand machine. RJF

My wife and I use manual wheelchairs. It's rare to see someone else in one other than the hospital. With a picture like that, I see a pattern coming! RJF One wheelchair note, Our family lived on the big island HI for several years. The town we lived in had old buildings with steps. We couldn't get into one store. Another odd thing there is not one store had a public washroom and posted employees only washrooms. Was an odd outing as we tried to figure out were to go to the bathroom away from our place. RJF

Got to remember wood is a natural product. Trees don't know we all want perfect boards. RJF

One shop home tool I got years ago has been a great home, workshop, craft tool. That's a Dremel. Between drilling fine holes, 'A given on circuit boards to put in electronics', sanding, grinding, etching, even cutting. They have a paper cutting wheel that shreds easily, I got an aftermarket disk cutter. We have a car top case for groceries, cause our wheelchairs to fill the back. Some idiot filled the mini padlock keyholes. Strung an electric cord outside and cut the mini padlock off in seconds. Used it for buffins small metal, jewelry and grinding a car part to fit. Have a mount for it, so I can hold the work like fretwork and sand in small spots. Been a great tool. Another tool is an oscillating cutter. Rockler makes one that is universal, so any other brand fits. Fast smooth cutting and sanding in spots. RJF

The one thing most people don't do on finishes is sanding well before and in between coats. The brush marks would be sanded out. As far as how high to go on grit is an internet forum topic. Some cut off at 220, 400 and there are those that feel they haven't gotten a good finish till they reach 6000. Brush marks are also dependant on the brush. Artist and house painters wouldn't buy a cheap brush cause it shows in the work. I became interested in drawing, sketch from the days when we had to use drafting boards, or sketch out an idea. I have studied and dabbled in sketching, watercolors, and airbrush. I've also been one of those kids that took everything apart to see how it works, watch home show and subscribed to Popular Mechanics from a young age, then woodworking mag. When I returned to doing scrollsaw patterns, I have had to start studying and playing with Inkscape and Gimp. Since woodworking is a craft and trade, the ideas and information is vast and goes back years. The above ideas are from my own work, mixed with working in the trades and extensive reading, tv, and internet. Brush marks in the finish is a constant topic I've seen from forums and magazines and even tv wood shows. No one wants their finish ruined on a new dining table or cabinet. The viscosity of the finish or 'thickness' is even debated since a thicker finish will spread less leaving brush marks. Thin the finish, don't thin it? Use a throwaway brush, use a good brush, use a foam brush. Most pro recommendations will work for what finish the pro works with.RJF

So that's why they are always out of it when I go... They see you coming. RJF

Use my posted method of a double boiler and you can't get too hot. Just find a pan/ metal bowl that fits on top of a pan. Use hot pads, gloves, plyers to remove to top bowl/ pan. The thermometer can lay in the top pan since it won't touch the heat. Can disregard keeping the thermometer from touching the pan. I'm converting a cargo trailer to an RV and looked at cooking the main electric cooking everyone is using is an inductive cooktop. Cheap works by plugging in, the heat goes directly to the pan with no heat loss. RJF Changed the bottom link, cheaper/ more popular.

Cataloging your recipe and looked up cutting board oil and beeswax. The listing shows the granules. They are white and yellow granules. I think you got the one with a yellow dye, Don't know what that will do on the finish. This IS a white one too.

Look at essential oils. Since this is an oil based recipe, the oils will mix. There are water based also. RJF https://www.amazon.com/s?k=essential+oils&crid=3SK7FRDVMKPNT&sprefix=essentail+%2Caps%2C354&ref=nb_sb_ss_sc_1_10

Create a 'double boiler'. Put water in a pan and put another pan, metal bowl over that pan. The heated water will heat the pan. Don't have to boil the water, just simmer. You can control the heat by putting the bowl on and off the pan. This cooking technique is used for melting chocolate, cooking eggs, and other recipes that more heat control is needed. You will separate the mixture from the flame and have more control over it. Beeswax; Beeswax has a relatively low melting point range of 62 to 64 °C (144 to 147 °F). If beeswax is heated above 85 °C (185 °F) discoloration occurs. The flash point of beeswax is 204.4 °C (400 °F). Your safe in the 150 F range, since beeswax will flash/ burn at 204, so you have another 50-degree range for it to burn. Looking at the melting point, it's just melting at 147, so you have to get close to 150 to get it to melt. Watch the flame, if you do it often, get a hotplate, which can be cheap and won't have a flame to ignite the mixture. https://www.amazon.com/Techwood-Portable-Single-Burner-Infrared/dp/B07H9PTSW8/ref=sr_1_4?ascsubtag=1ba00-01000-org00-win10-dsk00-nomod-us000-gatwy-feature-SEARC&keywords=electric+hotplate&qid=1555114160&s=gateway&sr=8-4 Nice first video.

Make a PVC divider and cover it with a piece of cheap fabric. Weight it down with concrete blocks stand bags, sand in gym socks tied off. A couple of these can cut the wind. If you use a tent, put fabric between the legs and weight the legs. RJF PVC-stage-backdrop-or-room-divider.pdf

Try laying masking tape on both sides then put the pattern. Works for a circular saw. RJF

Aren't you suppose to scrollsaw the banner? RJF

I'm traditional and don't use power. I use an abacus to print patterns. RJF

I don't use computers, lasers or cnc to cut any of my work. Little elves come in at night and do all the work! RJF

I lived there so far back both the aircraft carrier and submarine I served have been sunk. Folks that serve on subs generally don't serve on the surface. Strange trade, but they needed a tech to troubleshoot problems. I was traded in a bar conversation. RJF

I don't know if the Navy still uses the Bremerton Ship Yard. In the Puget Sound Bay west of Seattle. Everything rusted and it constantly rained holding up projects. I could never figure out why the site was ever picked. RJF

OH NO! We had to all get air grinders, THEN when the entire deck was ground down and checked by an Officer we were to go get the grit coating. If you can imagine the size of the top of an aircraft carrier, we worked with a hand grinder on our knees, about 10 enlisted. I think my back and knees are shot from weeks of kneeling on a steel deck. RJF

Took a few cut and pastes to find it in the US. Will put it on a future list. RJF https://www.amazon.com/gp/product/handle-buy-box/ref=dp_start-bbf_1_glance

You mention auto body several times, I'm surprised you don't detail cars every once in a while. RJF

The autobody and car stuff could probably be found locally. I come from a world of science labs and industrial labs. The article works on reference to compounds for the material and reference to type wheel. I buffed a collection of pennies dated from the first year of marriage to 50th Anniversary with their wedding picture in the middle. All the pennies were in date order mounted in fostner holes then clear coated. Gave it to inlaws. RJF
