How to install blade in very old model of craftsman scroll saw model 110.27500

Each blade thickness requires a different amount of tension on the blade. Your owners manual will give recommendations on how tight each should be. If you dont have a manual look for the model number and you will be able to find the manual online

Before you begin, make sure that the saw is unplugged. This is to ensure that the saw is not inadvertently turned on and helps prevent electrical shock.

Step 2 - Loosen the Screws or Bolts

The manufacturer will likely use two screws, bolts or turnable knobs to keep the blade in place. If you are working with a table scroll saw, one screw may be located at the top and one at the bottom. Handheld saws may have one screw in the front and another at the top. Refer to the saw's instructional manual if you have difficulty locating them. Loosen the screws using the appropriate screwdriver or Allen wrench. In most cases you should not completely remove them.

Step 3 - Remove the Old Scroll Saw Blade

Once the screws have been loosened enough, you are ready to remove the blade. If you are dealing with a table scroll saw, the blade should be pulled up and towards you as you remove it. Hand-held saws may require that you move the blade sideways away from the screw and then down. Others may simply fall out as you loosen the screws. Again, refer to the instructional manual if you have difficulty figuring out how to remove the blade.

Step 4 - Choose and Examine the New Blade

Once the old blade is removed, you should choose the new scroll saw blade you wish to install. Determine if you want a thin blade, thicker blade or a heavy duty blade. The blade should be inserted with the teeth facing downwards, although some blades may have teeth that face both upwards and downwards to achieve a smoother cut. Any questions should be referred to the instructional manual.

Step 5 - Insert the New Scroll Saw Blade

Locate the two holes on the new blade and insert it in the opposite way the old blade was removed. For example, if the old blade was removed by pulling it up and towards you, the new blade should be inserted downwards and away from you. The two holes are for the screws to hold the blade in place.

Step 6 - Tighten the Screws

With the new blade in place, tighten the screws but allow for some adjustment in getting the blade straight. Once the blade is straight, you can proceed in tightening both screws enough so that the blade is no longer loose.

Step 7 - Test It Out

Turn on the saw and test the new blade to make sure that it is not loose and has been installed correctly. If necessary, tighten the screws or adjust the blade so that it is straight and facing the right way.

Once you determine the blade has been installed correctly, you're ready to begin cutting.

the blades will have small pins at each end
fit it in the table end first as this is the end that does the work
then pull the top down to fit the blade in the slot
The top is normally only spring loaded

Which Scroll Saw are you using...there are multiple brands and multiple models. Help us out and tell us which one you have.

Most of the time there is a clamping mechanism that holds the top of the blade in place. Many models have a door or some access point to the lower end of the blade, too, which you'll have to get to as well.

You'll also usually find that there is some type of blade tension device that needs to be released and then reset before you can install and use a new blade. Make sure the new blade is the same length as the old one, also, make sure that it's the same type of blade, some have a small pin top and bottom, some do not.

Finally, check out YouTube and see if anyone has put up a video for your brand of Scroll Saw. May be the answer.

Good luck and be safe.

Loosen the knob at the rear of the top arm - turn it counterclockwise several turns. The blade should now be loose. Push the "blade end" of the top arm down slightly with one hand while you unhook the top of the blade. Lower the blade a little to unhook it from the bottom arm.

Replace the blade. Hook it onto the lower arm first - you can look underneath to see what you're doing. The blade's teeth should point DOWNWARD - it's easy to accidentally install it the wrong way, so check that now. Again push down slightly on the end of the upper arm, then hook the top of the blade into the upper arm's blade holder. It should how stay in place, but loosely.

Now return to that tensioning knob at the top rear. Tighten it slowly until the blade is BARELY tight, not loose. Tighten the knob 1/2-turn to one full turn tighter to tension the blade.

You might be able to find the manual on the Sears site (this can be a frustrating search - but start with the model number). But even without the manual, this is pretty easy on most scroll saws. There is usually a plastic knob (about the size of a ketchup bottle lid) on top of the machine at the back. You loosen this knob a couple of turns (to the left) and the blade will become very loose. The blade is probably the "pin-end" type - it will have a little cylinder about a 1/4 inch long on each end of the blade. You can buy new blades at any home improvement or hardware store. Besides qualtiy, the main differences will be the length of the blade and the size of the teeth (expressed as TPI or Teeth Per Inch). You need more TPI for cutting harder and thinnner materials, less TPI for softer and thicker material. Put the new blade in like the old one was (teeth pointing down) and tighten the plastic knob. It's hard to be sure how tight is should be, since it doesn't suddenly tighten up. About a 1/4 turn past where is starts to get noticeably tighter is a reasonable place to start. If the blade pops off during use, it wasn't tight enough.

Go to www.searspartsdirect.com and search by model number.

If you see a set screw where the blade goes, loosen it a few turns. Then run the saw, it should spit out the broken blade. If it has a manual release for the blade, press the release while tapping the blade holder.
