SRCarr, a member here can rebuild your bar hard face areas or re-make the mount area to fit your saw?

He can straighten and also build up and redress the chain slots.

I can hard face them with stellite and regrind the groove. I can also mill in bar mounts.

Evaluation of a used bar on Ebay.

This used bar was originally marketed for the Mac 10 and 600 series saws. It measures 14" across the radius and is 20" from the end of the slot to the tip of the bar. It is .050" and uses 85 driver links of 3/8" .050" gauge chain. It sold for $150 on Ebay in January 2015. It is a Oregon style D-176 mount with a 8mm wide slot. This bar was intended to be non reversible so the mount pattern is confusing for the oil hole (which is on the other side of the bar) is not seen. This bar is missing the guards. The Stellite is in good shape around the radius and the bar is straight. The label is a warning to read the instructions for proper use. The label has no model number or manufacturer information.

Another point of evaluation is that the seller did not make mention of the missing guard, the condition of the Stellite is shown more or less as a matter of chance(?) Sellers generally seem to fail to show much more than a casual picture of the bar with important factors like the typical wear area condition and straightness of the bar ignored?

The D176 mount also fits the typical 3500/3450/3750 Poulans without modification. I have a bar identical to this one and my mounting slot was widened from 8mm to 9mm (+.040") and the oil hole was moved out to align with the oil grove as on a Oregon D009 (big Husqvarna) .

This is the same model bar as in the previous post. Notice that it has been dolled up. Pretty and like new? You cannot see the condition of the Stellite hard face?

Notice the one sided D-176 mount and this time the seller showed the mounting side of the bar and the oil hole.

8mm=.315"   .3125" = 5/16"

Christmas Tree Bar

Referred to as a brush bar. This one is from a Homelite 4-20 of the late 1950's. The diameter across the radius is 8" and the bar is 24" long from the end of the slot to the tip. At this time there are two of these bars in the Ebay database and neither mentions the gauge however, it's likely .050"? One nice thing about a bow bar is that they are not pitch dependent. You can run whatever pitch common saw chain you desire for there is no tip sprocket.

This would work well on a 3 cube or 50 cc chainsaw? It sold for $36 a couple weeks ago.

Looking at the picture, this old rusty bar has good Stellite around the radius. At first glance it is bent on both sides? But, this is a "belly" to help keep the chain in the slot. Take notice of the brass stop or dog.

Did all bow bars come with a guard, or does that depend on the saw and design of the clutch cover.

AFAIK most at least had the top guard. But you probably noticed the brush bow in the post above was never drilled for a guard?

The seller gave me a top and bottom guard for my bar but I plan on only using one on the top. Or at least try it that way? The bar was drilled for guards top and bottom.

The two guards I have are identical.

The fact that the brush or Christmas tree bar didn't have holes for guards probably has more to do with the fact that the bar was made in the late 1950's instead of the early 1980's like the others?

More Bar Evaluation


This bar is the same brand as the other broad 14" bars bars but is a little older in that the slot is in the middle but is reversible.

One additional thing to take notice of is the Stellite that has been added to the mouth of the bar at the corners. I have seen this on several other bars of this brand whatever it is.


It happened to come from a early Pre-chain brake 61cc Stihl 041 which places it in the late 60's to early 1970's?
The only problem with a middle slot is that a lot of the bar is higher on the mount which means more modification to the chain cover and chain plates.

This seller must be reading this thread? The following are pluses for the buyer's evaluation of the bar?
He didn't refinish the bar
He shows a close up of the saw side of the mount with the oil hole
He shows a close up of the Stellite hard face overlay (The shiny - non rusty rail edges on the radius of the bar) and its condition.



In the description, the seller says exactly which saw it was mounted on when he obtained the bar and his evaluation of the bar's condition. This seller knows exactly what he has and is asking top dollar for it? Though this is a nice bar, there is no mention of gauge. Personally, the gauge wouldn't be so important to me. I'd just use a chain the right gauge to fit the bar.

Well I bought a bow saw and should have it by the end of this week.   I will post a picture of it when it get it and test it out.
This will be the first one of these for me.
