@dramdani @mikesc Just a few posts above, is this post! And by the way, this is not the same bag as in the video linked above. Its source is https://www.etsy.com/ca/listing/582183857/bag-pattern-leather-diy-pdf-download?ref=shop_home_active_28&pro=1 Tom

@archerydude If you type the at '@' symbol followed by a username, click on their username from the popup list and type, they will normally get a email depending on their settings, for the post you are making. Just like I did here. Tom

When you click quote, this (above) is what happens! If you highlight a piece of text a box pops up "Quote Selection". If you click on it, it places that selection in the reply box after the last post in the topic thread. Just like this: There is an envelop icon just to the left of your username at the top of the current window. Click it and see what happens. To contact a particular person you need to start typing the username of that person and pick (click) on the list that pops up. You can also hover the mouse over the username in a post and a box pops up. One of the items at the bottom left of the box is "Message" which takes you directly to the PM System. If you go to the main page https://leatherworker.net/forum/ You can see a list of all the different forums with descriptions here on LW. You will find one that is called "Computer Help". It has "sticky" posts that stay at the top of the forum for common items that people often have questions about. The top 4 threads are 1. How to post pictures on LW, 2. Inserting link into topic, 3. Picture resizing, 4. Tips on backing up your data. All good topics to review. Tom

go to the top right of the screen to your username and click on it. You should get a drop down box with selections for profile, settings, etc. Tom

@chouinardragon You should update your profile with your location so people have a better idea of where you may be able to buy a machine, that might even be more local to you. Or so they and you know that here will be overseas shipping from USA. It appears from your IP address that your are in Taiwan. Tom

That's a good solution as long as your work space fits. I have MCS (Multiple Chemical Sensitivity) so am more concerned about keeping the vapours out of my space. "Comfort" Tom

@Scarolamade Moved your post to "leather sewing machines". You'll get more comments and action here. Have you searched this forum for replacing timing belts? Tom

I'd pick either one of the larger bathroom exhaust fans (with a low sound level) or a range hood. Need to keep all we have! Tom

I would cross post this under leather sewing machines since most guys that would have some ideas for you frequent that forum. Tom

Really great piece of work, should say really great piece of art! Tom

The head page says Resources: Links, periodicals, books, Guilds and other professional organizations, trade show and demonstration announcements go here. So I believe you are in the right place. Fire away, full steam ahead! Tom

Another dumb story! I had a wet distributor cap after washing down my car's engine. So I took the cap off, rinsed it with methyl hydrate (alcohol) wiped it out, plugged all the spark plug wires and coil wire back in and put the cap back in place. Climbed in the car and hit the starter. BANG! Didn't start! Checked under the hood. It had blown the distributor cap off. So had just enough fumes, plus a spark, and off she went! Haven't tried that since and that's over 40 years ago. Tom

Myth or no myth? Let's get the information relative to whether solvent vapours are explosive or not. For an explosion to happen, there needs to be a high enough concentration of the flammable vapours exceeding the lower explosive limit (LEL). It is different for various vapours and gases. If you keep enough air moving through the space, no problem with explosions. Hydrogen is one of the worst with the widest explosive range. Lower Explosive Limit (LEL) 4% in air, Upper Explosive Limit (UEL) 75% in air. See the following for more information on other vapours and gases: http://www.wermac.org/safety/safety_what_is_lel_and_uel.html I know of a house (next door to my MIL) that blew up. They were installing carpet in the basement, using a glue with a very volatile solvent. They were just about finished when the vapours hit the gas fired hot water heater and ignited. Lost the whole house (insurance built them a really nice replacement). Most of these solvent's vapours are heavier than air, so sink to the lowest area. Thus the basement without adequate air exchange became a disaster. If we assume that toluene is the solvent, its LEL is 1.2% and UEL is 7.1%. So if the concentration by volume in air is in the range of 1.2 to 7.1%, and there is a source of ignition, there will be an explosion. Toluene is a common strong solvent. One weekend many years ago, I was working as Shift Supervisor in the Utilities Plant just across a service lane from the Gas Compressor House. The Refinery produced hydrogen and used it in a hydrogenation process to remove sulfur from the hydrocarbon streams used in the manufacture of diesel and gasoline. The two hydrogen compressors (1200 hp 3 stages each) were located along with other compressors in the compressor house. They raise the hydrogen pressure to 1200 psig for the Unifiners. I get a phone call from the Process Shift Supervisor. They have a hydrogen leak and have 95% hydrogen atmosphere in the Compressor House. Of course it was safe from causing an explosion since the atmosphere was well above the UEL. How to get from there back to hydrogen free, while passing through the explosive zone? No one can enter it without a Scot Air Pack (no oxygen to breath), no one can shut off the electric drives or switch anything for fear of creating a spark even though all the wiring is in sealed explosion proof conduit and boxes. Can't take the risk. They bring in the plant fire crew with some new fans they had purchased recently that ran on water pressure and placed them in the doorways to ventilate the building without doing anything inside the building, and to avoid adding any risk of generating a spark. Even outside the building, gas was above the LEL. We monitored the % LEL in the Utilities Plant 50 feet from the Compressor House. The drift and seepage of the hydrogen into the Utilities Plant raised the % LEL in the building to 2%. We had 3 large boilers that were potential sources of ignition if the hydrogen level got too high. Anyhow, to make a long story short, they were able to ventilate the Compressor House successfully with no fire or explosion. Funny thing was that they couldn't find the source of the hydrogen leak. Must have blown an oil seal and had it reform by itself. Tom

You are really getting the hang of it. I like your work! Tom

@jbennion Moved your post to leather sewing machines. You are more likely to get answers here. You might like to add your location to your profile since you are interested in visiting a shop. You might get invitations from Mars or Venus otherwise! This is a worldwide forum. Have you done any internet searches for Singer 97-10? there are manuals available on some sites. Welcome to the forum. The best all around leather working site available. Tom

I suppose you could run an engine driven compressor for compressed air. Also need power for the solenoids, though it may be only 24 v. So if I was going to setup for work "in the deep woods" I would just use a standard machine and hook up to an gasoline or diesel engine driven electric generator. I know some people use propane fueled engines on their generators. For more permanent locations with natural gas available (no electric utility) I would install a Generac 20 kW generator set. I helped install one for backup power in an area subject to frequent power outages during summer rains and floods. Can run on nat gas or propane. Certainly allows one to sleep better and have peace of mind knowing you can keep two 1 hp sump pumps running! Tom

Moved this from "wanted" to "sewing machines" since you have posted similar in used. Wanted requires moderator approval for every post. Tom

OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker's time weighted average over an 8 hour day. With noise, OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. The OSHA standard uses a 5 dBA exchange rate. Other jurisdictions may use 85dBA as the limit. That is fairly loud in comparison to tooling leather. Comparison chart https://www.noisehelp.com/noise-level-chart.html Safe noise levels https://www.noisehelp.com/noise-dose.html Tom

Also pull the thread out of the needle or you'll likely have a big birds nest to deal with. Tom

Users can't delete. Just mark as sold, and we take care of it. It gets locked and moved to old/sold. Tom

Definitely! I should have mentioned that! Tom

It's the solvent that is used in spirit based dyes that is the problem in California. Whether it is regular or Pro dye, same problem. Tom

@Blueboost Add a picture or two ... add some specs so people don't have to go look it up, maybe that will help generate some interest for you. Tom
