Hardtip vers rollertip

[jhellwig]

If you are using a roller tip with a big enough roller it will roll any pitch. I only have a few actual roller tips and most of them will roll over 3/8. The same applies to hard tips, as long as the tip has enough radius to accommodate the drive links they will work. Sprocket tips are pitch specific.

Woah there! I thought there was only 2 types of bars. Someone educate me please!

eh

I was speaking mainly of greasable tips, but I'm sure you knew that.

Actually I didn't know there were greasable tips... that something outdated or something??? I always thought the only maint was cleaning out the groove and getting it dressed every several hundred cord of firewood... opcorn:

I take advantage of any cheap bars I can get in usable condition and end up with several hardnose bars. They are easier for me to dress the rails and I like them on saws that have plenty of torque to pull them.Right now I run my ms660 with one in 25" and my 041av wears one 20".My 026 I use a 20" sprocket nose and the 044 has a 25" sprocket nose.

Roller tip has a "wheel","roller", or "toothless sprocket" riveted to the end of a bar in a similar fashion as a normal sprocket tip. You can run many different pitch sizes. They tend to be hard to find as the attachment point and roller bearings tend to fail on the older ones and new one can be hard to order/find and expensive.

Hard tip has no moving part on the end but usually a different grade of steel attached to the tip.

Sprocket tip has a sprocket suspended by bearings(hopefully) built into or non-permenantly attached to the end of a bar.

Bow bars are large hooped rails on which the chain rides designed to allow for ground cutting with less tip pinching, operator bending and improved bar wear.

Brush bars are smaller height but as long if not longer bow bars used to cut small brush and small trees down. Similar to a bow bar in appearances but the two should be used for their own purposes.

"Rescue" bars or vent bars are angled downward from the saw and used to cut holes in floors, roofs, walls , etc. Pricey.

There are also the wide variety of saw chain "bars" used for mounting chain up to various sizes of angle grinders, circular saws, weed wackers(oops, brush cutters) and other non traditional chainsaws. These usually amount to two circular metal discs with the chain placed between them held together by the tools traditional mount. Sometimes with some additional bolts through the discs to prevent slippage.

Some two man bars have to have a !itch handle with a sprocket built in.

There are also bars for mounting a saw at each end.

I feel educated now. Thankyou.
