Found a DB chainsaw for sale local. Listed as a 1952 with a 24 inch bar. Unknown if it runs.

I think I want it. Can anybody tell me anything about them? Good,bad or ?????????

Thanks.

Probably has a Power Products engine.  They are neat lookers, and sure do get attention. 

 

I don't know what size chain it uses, anyone here know?  That's where it can get interesting.

At that age, it would be hard to say without knowing the model, my guess would be .404 chain. Anything can be good for the right price, even if it wont run it would make a good shelf piece.

Yes and even after Sears phased out the DB saw.

 

As for the chain it depends on the year and make of the saw, 1/2 inch to 3/8.

Anybody have one?.

Does it cut well?

I plan on using it regularly if I get it and it runs or will run with minimal work and money.

I cant find any reliable specs on it. Anybody found anything before hidden away on the internet?

Does look pretty neat.

Anything other than vague chain facts?

Would this be considered a two man saw?

From what Ive seen on the youtube it looks to be gear drive. Is that right?

Thanks.

I have two, one gear drive, one direct drive they are the later metallic blue ones.

 

All are powered by the Power Products engine.

 

Just about all parts are NLA, the gear drive uses the 1/2 pitch chain, the direct drive is 3/8 pitch chain which i used some, both are very heavy and slow compared to modern ''zip'' saws. The gear drive was very slow but ripped out 1/8 strips/chippings and worked all day on a few tank fills.

 

I would stick to the new saws and save the old monsters for show and tell, with no muffler to call for it will deafen the neighborhood.

 

The model 360 has become the most sough ofter saw.

As with most DB items, you have to have a model number to be able to tell much about them. This goes for tractors, tillers, saws and about 50 other items. One of the greatest thing ever done, was Sears had a data base for telling you by this number what the item was. I have a few saw manuals here, but without the model number, its a hopeless task to figure out which of the zillion products it is.

The U model was made for a long while as the cheaper saw, model did not change much so was seen into the late 60's early 70's under Sears and others, there was a bunch of U made with gear drives, they were very good saws and still are.

 

The tank is a split tank, 3/4 is fuel, 1/4 is bar oil, thumb push manual oiler, carbs were Tilly HL and HT on the early ones, Tech (model # eludes me) carbs on the later ones.

 

Later ones had baffles in the exhaust defector reducing the noise somewhat.

 

Chain is usually 3/8 or smaller, 16 inch bar.
