They are starting to question why waste raw material and resources to build something bigger than we would normally use. I really hope this catches on, we need to rethink our houses, cars, planes, office space, and even tools. Do we really need a 25 horse power table saw to build bird houses or bandsaws with 25" wheels and 5 horse motors that have a 2 foot height capacity to saw pen blanks? Sure it is nice to say hey I bought this saw big so it can saw whatever I come up with but if we never use that capacity with some regularity we have really wasted material and resources on it.

My opinion unless you have a particular need that requires a large capacty than the Shopsmith bandsaw, the SS Bandsaw is probably the perfect size for most people. Sure there are times I would like another inch of capacity here or there but 99% time my bandsaw meets my needs and for those other 1% of the times there is usually a work around that solves the problem.

I think the biggest problem with the SS bandsaw is most users try to do everything with one or two blades. Theytry to cut too tight with a 1/2" blade or they get frustrated when they can't rip perfectly straight 5 foot pieces with 1/8" blade. There is a huge number of blades, with varying tooth patterns, teeth set, width, material type so the blade can be matched to the job.
No "highjacking" detected in this post! You ARE flapping about Band Saws not bugs or fish or whales.:)

How does one get a good smooth cut with the bandsaw? I'm thinking that I just need more practice at it. I keep getting gouges along the cut. The blade is a 1/4 14TPI.

The reason in asking is,, I have an arm to cut out soon for a chair.

Please define 'gouges'. Size? Regularity? Type of blade?

A photo would be appreciated much more than a description.

I recently took a class from David Marks at the Woodcraft Store in Boise. Mr. Marks used to have a woodworking program on HGTV. The class was on resawing on an oversized bandsaw. It was a great class and I learned a lot tricks.

The bandsaw manual is great. But, there are times when hands on training is the best way. I would recommend this class to anyone who has the time and money.

Bob,

If you cut a straight or near straight line with that same blade would you have the unwanted gouges?

It sorta looks to me that the 1/4" blade might be just a bit to wide for the arc that you are trying to cut.

Have you tried this same procedure with a narrower (1/8") blade.

PS to previous post.

I attempted to create some sample cuts of what I thought might be happening to you. These pictures are not very good quality but if they were you would see that the only problems are some burning when trying to cut to tight a turn. There is no gouging. As a point of reference, the piece of plywood is 2 5/8" wide.

One point though. The back edges of this blade had been filed round to aid in tight cuts. I was cutting tight enough circle that the blade was twisting.

Sorry - this might not be your problem. Likely is NOT.

Blade Bent(at one point)? Does 'gouging' occur only on one side of blade??? Is a tooth bent(excessive set)?

I am groping here!:confused:

Have you tried another blade with coarser teeth (6TPI)? Also are your tension and blade guides set correctly?
