For anyone using the Speed Changer the belt sizes are 4L220 and 4L250 or 22" and 25". The original belts for the Speed Changer were 22.5" and 25.5" but those 1/2" size belts (4L225 & 4L255) are no longer found.

I believe I found some

Did you look at the specs?

The Gates 4L255 is listed as 25" length and the Browning 4L225 is listed as 21.5" length.

I did read the specs but was hoping the 21.5 “pitch length” was possibly for inside circumference. I’m not a belt expert though I have some.

Both are from MRO

Gates 4L255 4L Section Truflex V-Belt

Cross Section: 4L

Outside Circumference: 25.5 Inch

Material ID: 84002255

But you may have me on the other one. I’m gonna call on Tuesday to find out what the deal is on the number 4L225, it’s representing what?

Why Not???

Once upon a time the 4L was a standard 1/2" belt.

But then also the 225 referenced a 22 1/2 inch belt.

So what gives???

Yeah it doesn’t make a lot of sense but not much does these days. I’ll try to find out the meaning of life in the V-belt world tomorrow.

JPG- per 2 separate sources you are correct.

Part number designation for wedge belts is shown in belt top width followed by the nominal outside length in inches. The numerical prefix indicates the belt top width in one-eighth of an inch. For example, the 5V500 part number indicates a 5/8” top width with a 50.0” outside length.

General cross-sectional dimensions that are used in the US are shown below.

Fractional Horsepower Belt:

FHP light-duty V-belts are often used as single belts on drives of 1 horsepower or less. Its design is for relatively light loads. The most common applications for this V-belt type are domestic washing machines, small fans, refrigerators, and garage equipment. Light V-belts should never be used on any heavy-duty industrial applications, even if they seem to fit the classical or narrow V-belt pulley grooves.

Part number designation for FHP belts is similar to wedge. They are identified with a 2L, 3L, 4L, or 5L prefix. The numerical prefix indicates the belt top width in one-eighth of an inch, followed by the nominal outside length in inches. For example, the 3L300 part number indicates a 3/8” top width with a 30.0” outer length.

Checked with manufacturer and the Browning 4L225 is in fact 22.5 inches in circumference. All is right now in the World of V-Belts.

Re the length 'discrepancy', the 4lxxx specifies the outer od. The smaller 'length' likely refers to pitch diameter which is the effective 'running' length.

How many things designed for the Mark V are compatible with the 10ER?

eBay has items listed for the Mark V and I heard somewhere some attachments could be used on the 10ER.

Thoughts?

Pretty much anything that mounts on the spindle or tailstock will work. With the proper adapter hardware, SPT’s (Special Purpose Tools) such as the bandsaw, jointer, etc. can be used as well. Original adapter hardware is hard to find, but you can buy high-quality aftermarket adapters at mkctools.com.

CaptainKirk,

Welcome to the Shopsmith Forum.

The link below is to a topic I started titled Shopsmith Model 10's What When and Where in the Community section. It has a lot of information on the Model 10E and 10ER plus accessories.

https://forum.shopsmith.com/viewtopic.php?t=23647

Both the Model 10's and the Mark Series tools have the same size Spindle and Quill Diameter. Many of the Mark accessories can be used on a Model 10E or 10ER. A lot of the Spindle/Quill Accessories still in use today originally came from the Model 10's. Not all Mark accessories can be use on a Model 10 though.

Below is a link to a similar topic I started titled Shopsmith Mark 5 What When and Where found in the Community section.

https://forum.shopsmith.com/viewtopic.php?t=24963

The link below is for the topic I did titled SPT's What When and Where in the Community section.

https://forum.shopsmith.com/viewtopic.php?t=26072

You may find helpful information in all three of these topics.

Something I like to suggest to new members is to start your own topic where you can have the information you seek in one location as opposed to being spread out in several places. A great way to refer back to questions and answers you have had.

How tight should the upper saw guard be on the splitter? I have my dad’s old 10ER and the guard is extremely tight, which makes it difficult to move and it stays exactly where you put it. I was under the impression that it should more or less float on the splitter. I’ve cleaned up the splitter with no significant improvement. The slot in the guard doesn’t look bent either, and is clear.

chapmanruss

I recommend installing the screw by putting it in the threaded side first. The end of the screw will sit inside the unthreaded side of the Upper Saw Guard. This helps lock the screw in place without binding the Splitter between the two sides of the Guard. The screw is simply a pivot point.

The OEM screw is a standard Round Head Machine Screw 1/4" - 20 x 3/4".

Akela9

Thank you. That’s good information. I’m actually already putting the screw in that way, as it’s the way my dad had it assembled. I’m fairly sure it’s the original screw as it fits the threads perfectly and is not hard to screw in. But I have no gauge to measure it at home.

The fit is tight even with the screw removed, but only in the part of the slot forward of the screw hole. Perhaps I should file out that part of the slot. The area of the slot behind the screw is plenty loose and is visibly a wider gap.

Try GENTLY prying the slot wider.

chapmanruss

If the Upper Saw Blade Guard has been re-painted, paint could be "clogging" up the slot causing more friction for the Splitter. You could try folding a piece of sandpaper in half and working it into the Splitter Slot and sand down the surfaces. Emery Boards can be used too.

JPG's suggestion of GENTLY prying the slot wider can work but it is easy to break the Guard that way. Don't ask me how I know. :o

Akela9

Thank you JPG and Russ. I promise I won’t ask any prying questions. ;)
