Haven't noticed, Do you ever get chapped screws? RJF

Her is one way to keep stain, paint off of areas RJF https://www.amazon.com/Winsor-Newton-Masking-Fluid-75ml/dp/B005P1ROEY/ref=sr_1_1?crid=24Q2UHYBUMMUH&keywords=liquid+masking+for+painting&qid=1552162936&s=gateway&sprefix=liquid+painting+ma%2Caps%2C265&sr=8-1

One adaption I have seen for drill press and table saws are precut base angles with a clamp, then the base is slide around on a flat level surface and the work is angled. Keeps from going back and forth on angling the table. Probably most of the people on the board with complete wood shops have read or heard of this. RJF

Thank you, Noticed I replied to the topic for vibration. Absolutely forgot about the was, cut it came to mind. Now to find where I put my glasses. RJF

Every heard of or experimented with using a candle or canning paraffin and waxing the blade. IE running the blade and pushing a little wax into it to coat as a lubricant? RJF

Called Hawk (3rd Time) Today About The New Saw
teachnlearn replied to kmmcrafts's topic in General Scroll Sawing
Yep, think I'll scroll fretwork on the steel. Anyone want o buy a fretwork bridge? RJF -
Check out wood glues. Many wood magazines have reviewed titebond wood glue. Seen debates on whether titebond III is worth it. Just check out outdoor, waterproof glues. Being waterproof should take washings, but the dishwasher may not handle it. Epoxy will work and then there will be the decision of which for setup time. Epoxy has a lot of strength, generally the more setting time the stronger. For a spoon, it may be overkill, unless an elephant is using it. General outdoor project building uses an outdoor glue. Just double check with manufactures if it can be used for food, ie eating. Many projects are put on walls or display and spoons tend to be carved out of one piece of wood. link for titebond RJFhttps://www.amazon.com/s?k=titebond+wood+glue&ascsubtag=1ba00-01000-a0049-win10-dsk00-nomod-us000-gatwy-feature-SEARC&tag=amz-mkt-fox-us-20

Occurred to me with vibration as a topic coming up. I have had a private pilot lic. Kind of outside of the field of scroll sawing. I'm one of those people that have to know how things work and have a trail of childhood devices pulled apart, though I spent the rest of my life putting everything together for my family after the fact. Hung around airplane hangers watching the mechanics work of the plane to understand the insides. One requirement for planes is all bolts and nuts have holes in them. A bolt and nut is tightened to a spec and the holes line up, then "safety wire" is put through the hole and other bolt holes or anchor the stop the bolt and nut from twisting. For cars, scrollsaws that have bolts that just won't stay some safety wire and a hole drill through will keep it there until you cut the wire. There is the safety wire and a plier that has a spin knob to twist the wire. There is different sizes of wire and even some jigs to drill right through the nut and bolt. I doubt everyone is going to run out and safety wire everything on their scroll saw, though when you have had enough of a bolt coming out this is one way that keeps planes up and is dependable. Utube link to give some an idea if you haven't heard of it. RJF https://www.youtube.com/results?search_query=safetwire+bolts

Using a nut and double locking might work. If there isn't space, putting the nut on the end of a bolt and grind thinner. Loctite has a variety of colors. Offhand I know red is permanent. If you go to an auto parts store they tend to stock a few more colors then the hardware store. Online from Amazon is a line of Loctite, which I suggest a check on the Loctite site to check what you use you eant.. http://www.loctite.com/en/channel-switch/usa.html http://henkeladhesivesna.com/blog/the-difference-between-red-blue-green-and-purple-threadlockers/ Advisor and product listing didn't see some colors though http://www.loctiteproducts.com/adhesive-sealant-products.shtml RJF

Probably not needed all the time. Saw a youtube on a project and he glued the pattern to cardboard before trying it he taped it up to see if that's what he wanted. Good test way for most small shop projects. Matter of fact I would go with a large frig box for a large project with expensive wood. RJF

Scroll saws with little or no vibration at full speed

Haven't had a new machine since my purchase in 1975. My wife has the checkbook and its very tough to convince her. Until this scroll saw dies, I only get to look. RJF -
Scroll saws with little or no vibration at full speed
teachnlearn replied to annis's topic in General Scroll Sawing
One of my backgrounds is electronic engineering which I dealt with very small electronic components. After being in that field for years my college study of physics, mechanics, fluid dynamics is not as keen, though I try to keep a basic grasp. My field was automation so I would pull the books on the specifics. I'm writing on the fly so I could be off. When you mentioned a "stand" I assumed, "ups", that it was a solid triangle base stand used in shop machines. I'm disabled now and the brain still spins, so I approach problems and look for solutions. Your scroll saw may very well be constructed well and need little. I've got a Craftsman contractors model that is heavy, but their design has an arm that rattles away. Horrible noise, but little vibration on the table. Had just posted a note in the introduction on handling scroll saw noise in an apartment and might have had some sound theories still rattling in my brain. I quoted yours to give an example of weight, hopefully not to offend but to continue an example. Designing our vibration and sound is a constant problem while the cost people cheapen the materials. My apologies if my post somehow came across as accusing. RJF -
Scroll saws with little or no vibration at full speed
teachnlearn replied to annis's topic in General Scroll Sawing
Just replied on introduction sound transmission. Vibration is transmitted straight through metal easily. The vibration is a factor of "sound strength", the mass of the substance it's going through and isolation. "Build tolerances and balance" are qualities of any machine which lows the strength of the vibration. When a machine has isolation, such as large rubber .groments at the motor, rubber grommets at all moving parts and rubber feet, this would be "isolation" , US submarines have pipes and decking all strapped with isolation bumpers to isolate the sound. The "mass" or what we call weight is a factor. You mention a stand, which you are adding weight. Construction glue a vibrating cell phone to a large heavy table and see if that baby has the same vibration. It's the additional weight, which is why we are so frustrated with the "junk plastic' We get for so many shop tools. Buy a 15,000 dollar lathe and see what the weight of that beast will be. When you cut the wood on this lathe the weight will keep it rock solid in place, no vibration. Mount a vise on a folding table and clamp rebar in it and hammer it over. Now "an auto garage did this", take a 55-gallon drum fill it with concrete and mount the vise to the concrete. Now you can beat the rebar into a pretzel and the drum and vise will be stable. Again large weight and little vibration. Basic example with extreme figures to demonstrate the principle. Rick RJF -
Blade slippage tip (or a no no?)
teachnlearn replied to savethebeer's topic in General Scroll Sawing
SD Good has a set of videos on this subject. Can't take any credit for his knowledge or generous teaching other than direct you to a set Rick, RJF https://www.youtube.com/results?search_query=sd+good+scroll+saw+blade+slip -
By the way there are also sound products for cars that come as sheets for the floor, roof, trunk, hood, doors. Just check soundproofing automobile or car. RJF An added idea, mix DIY and some pro products. Haven't seen this, but it will be more expensive than DIY, but more noise reduction and less expensive than going total professional products. RJF

Our family has lived in apartments for 20 years. I do have a scroll saw and used it in a corner apartment. Sound travels by conduction via waves. Scroll saws are shop tools are do make quite a bit of noise. One question for the board would be who's brand seems to be quiet. I have an old Craftsman and its a noisy beast. We have lived with neighbors, that are inconsiderate and make as much noise with the kids and stomping on our ceiling. Have researched a lot on noise control, though there are DIY ways they are not as effective as the professional products that are pricey. The first idea is to isolate the noise of the machine which has a vibration through the table to the floor, the other would be the transmission by air. Using a thick rubber padding under the machine will help, another under the cart and table will help more. https://www.amazon.com/s?k=rubber+floor+tiles&ascsubtag=1ba00-01000-a0049-win10-dsk00-nomod-us000-gatwy-feature-SEARC&tag=amz-mkt-fox-us-20 This can be put together flooring mats or professional stuff. The second area is transmission by air. One would be making a booth with plywood and covering with foam or old blankets, quilts. Another would be a PVC booth and hanging blankets, quilts. https://www.instructables.com/id/Simple-Spray-Booth-for-Around-70/ This booth is a DIY project that folks have done in workshops and homes for crafts and spray paint booths using clamps to help hang plastic. Another is to dampen noise transmission through walls by hanging quilts. Ceilings are tougher. The DIY works, but by no means as well as the professional products. These are specially designed foams, and systems to build a second wall and sound insulate it from the main wall and ceiling. https://www.google.com/search?client=firefox-b-1-d&q=soundproofing+store and https://www.soundproofstore.com/ If you go the DIY route you will want to limit your cutting hours to times others are out or will accept a set amount of noise during the day. The professional products will really cut noise but gets expensive. One way to cut that is to build a scroll saw booth with pro products. The sound field is vast enough there are engineers that do just that as a job so this is just a very basic primer. RJF

Which direction do you scroll
teachnlearn replied to scrollingforsanity's topic in General Scroll Sawing
In a digital world, how do you figure out counter-clockwise and clockwise? -
This could be the answer and a Way, WAY, WAY overkill. This is used in the industry for permanent mounting. Few small pieces will hold it forever. Just make sure you place it once, cause it's going to be that way FOREVER! I used this in the industry and at home.

There are various grades of hot glue from a hot glue gun. Had an employer of a restaurant, hot glue a large microwave to a shelf. It stayed for the year I was there. Wouldn't have done that myself, but I was surprised it stayed that length of time. RJF

I ordered 8 of them that had hockey pucks and double stick adhesive mats, Having to do some woodworking in an apartment I have set them down on a parking lot double stacked and broken down 4 x 8 plywood, with a circular saw, worked and held it in place with no slip. RJF

Thank You. RJF

Did Electronic Engineering and consulting. Years ago did scrollsaw work on a 21-inch craftsman. Moved from IL to South Dakota several years ago and living in an apartment. Probably move to a house in the future and get back into scroll sawing. When I did scroll saw it was drawing the patterns, then tracing them with carbon paper onto the wood. Have worked with Computer Assisted Design, "CAD" and got some free image software for drawing. Still, dabble in electronics, but also have sketched and tinkered with carving and printing with Linoleum. Scroll Saw is in off-site storage so I'm designing patterns and reading on the updates of scroll sawing and new tools and techniques. My wife and I are both disabled vets, so I doubt we will ever be able to do any shows other than possibly sell online. Thats about it, just finished getting our car out of a parking lot snow drift.
