struggling with wormdrive

Bought a new bosch wormdrive circ saw (1677md) and I keep going back to my old underpowered standby.

Even on a short cross cut (2x10) it is tailing off badly to the left.

Any suggestions on adjustment/alignment?
Improper use versus a standard circ saw?
Lemon?

BTW - It has not been dropped or mishandled.

I cannot see how the drive mechanism should have any effect of the sawing qualities. I would more expect that the blade is not square to the shaft.

Do you eyeball the blade on your cut line or do you follow the cut line with the guide on the saw?

My worm drive kicks to the right when it starts up so I'd think if it was a torque issue, it would tail to the right. I inherited this saw from my father-in-law but after using it, I'd never buy one. It just feels way too cumbersome to use. As a result, I find myself most using my 1959 model Craftsman.

It may just be that the handling and feel is so much different than a regular circular saw. It may take some getting used to. Having the blade on the left may be an optical difference in using the saw. I prefer worm drives.

I have a Skil worm drive saw, and it performs well. I find there are some applications where it is just way easier to control than a standard circular saw. Try cutting some scraps of wood to get a better feel for the saw. It may be that you are unfamiliar with the operation of this type of saw. They do handle and feel a lot differently that a cs.

Wormdrives are powerful and fast cutting but typically have a narrow base plate. I like having the blade on the left but the handle on worm drives doesnt make them very one hand friendly. Fortunately I don't use a hand held circlesaw that much and prefer a wider, more ergonomically balanced saw with a wide, aluminum base plate. Most of my cross cutting gets done on the sliding compound miter saw anyway. I own a makita worm drive. It's very powerful but I rarely use it. It must weigh 15 pounds. The mag skils are some what lighter but still not a tool I would like to carry around on a roof or drag out to cut two or three boards. If I have stair stringers or acute angles on rafters then a worm drive is the ticket. If I have resizing or cuts to make on rafters and joists it gets done on the compound miter saw. They have a place.

But...back on topic...I can't imagine whats causing his cut to "tail off to the left" unless it would be a terribly dull blade (he didn't mention what blade he was using) or he is trying to guide the cut with the guide plate and it's misaligned (seems to happen more on worm drives because of the abuse they take)

A good thick speed square ( Empire or Craftsman ) works good as a guide if your doing 90 degree or 45 degree cuts.

I have a big old 8" craftsman worm drive. It is gathering dust in my tool shed. It has its purpose in life and I am glad I don't use it much. It cuts like a dream, just heavy to use. As for using mine on a daily basis, Not me. I am 6 foot 235lbs and that saw will wear me out by noon.
