Check the voltage at the outlet , where it is plugged into, to see if it is too low.

SOURCE: I have a Miller

I found similar problem with few customers and one issue (should I said the standard issue) is the source of air. You need a steady pressure and flow of air into the machine. Check your air compressor you will need at least 6 cubic feet per minute (360 cubic feet per hour) and a 90 psi of pressure. Since there is no way to check the flow (unless you have an online flow meter at you air pipe) check the pressure at your air tank (reservoir), if the pressure drops below the 70 PSI then that's the problem; your compressor can't stand the flow. Other than that check your ground clamp and make sure it's making a good contact.
Good Luck.

SOURCE: Plasma cutter started cutting at an angle even

notice the direction of cut. one edge will be straight and one beveled. the side you need should always be cut in that direction. example: if pulled the the right edge will be straight and if pushed the left edge will be straight.

Looking for new reed valve for Clarke Pioneer Twin Tank air compressor.

When factory reeds are not available, I generally use reed stock. What the heck is that you might ask. Reed stock is any material handy that will substitute for the factory reeds. I have used feeler gage material, reeds from other compressors cut down to size, hacksaw blades with saw edge ground off, rewind spring from various nailers and finally thin stainless steel sheets. You can be creative, all it needs to do is set nicely in the space provided. Another hint: Some reedvalve plates have one reed valve with several fingers acting over several matching ports. You can cut away the broken reedfinger leaving the remaining portion. Now you have an open port. All you need do is thread hole and apply treadlock to a piece of bolt cut to same thickness of plate. Good Luck

Fxing cracked carriers


As you know when a solid piece of material is damages, the structural integrity of the item is damaged, and it doesn't help that ABS is a very unfogiving material. I see Cartop Carriers all over my city with scuffs on them because the things are simply easy to forget that they are even up there!

In my research on your issue I found a material that should fix your cracked carrier and ensure that you will have many more years of enjoyment with it.

To answer your question, Fiberglass is not the proper material to use on ABS. Fiberglass is essentially a "Band-Aid" on ABS because the bond will only last a couple of years.

For this job you will need to use a compound called "Re-Plast" manufactured by the automotive parts company Wurth.

The benefit of Re-Plast is that it hardens into a plastic that bonds well with ABS, and it bonds FAST! So work quickly.

The Re-Plast will give your carrier a "scar" but should patch up your crack and increase your structural integrity. The good thing about Re=-Plast is that if you want to, you can paint over it to match your carrier's coat, to conceal the "scar" even better!

You can order Re-Plast directly from Wurth on their website link that is found below.

If this does not solve your issue, or if you have any more questions, please leave a comment on this thread and I will be more than happy to assist you further!

Happy New Year!

Feedback is appreciated!

When cutting 40mm mild steel with oxy/propane is it recommended to heat the plate before hand,and would a 1/16 nozzle be sufficient?

No heating the plate before cutting is never recommended and a 1/16 nozzle is small for cutting thicker steel, My recomendation is to get the next to largest tip for your torch and use that for most of your cutting needs as for thinner material you just keep the settings turned down and for thicker you have the capabilities to increase you gasses to addiquitly cut the thicker material. Hope This Helps Don

My Bernina 2000D wasn't sewing properly so I took it in for a service. Apparently the plate was cracked & it was replaced with a new one. However, it is still not sewing properly,the material is...

Have it fixed under warranty of the service you had done.

There could be many things... including the timing and using too thick a material. Have the service company show you that it is working using your material.

Sewing thick fabric and machine won't send it through

Sergers are not really meant to sew very thick material. The blades have a maximum amount of range, or thickness that they can reach to cut. If you go outside that range, get ready for a big repair bill! You can break loopers and even the needle plate when you "push" a serger. My advise would be to use you sewing machine for the, "pounding" work. The type of material matters too, A thick Quilt like fabric can be sewn becatuse it's not dense material. A thinner harder denim could max out at 3 layers because of it"s hard finish. If the fabric you're sewing isn't dense like, you could just need new knives.

Top thread breaks at start of stitching and often in the middle with no discernible reason.

check your hook for any burrs on it, if its the style that is a black composit material i would recommend buffing all around it because thread tends to cut into the sides of the hook.

I have a Makita 3901 plate joiner...what is the set plate used for?

It's used for cutting slots in thin workpieces, Look at page 6 of the manual linked here (it's a large manual, be patient while it downloads).

When you set the router at 45 degrees to cut a corner joint slot it raises the router 5/32 of an inch further to the inside corner so the slot doesn't break out of the thin material on the outside or face of the workpiece.

The picture on page 6 is worth a thousand words!
